Respiratory Equipment & Products
Bi-Level - Bi-Level system makes
breathing easier and more natural for adult patients
with Obstructive Sleep Apnea (OSA) who are having
difficulty complying with continuous positive airway
pressure therapy.
Continuous Positive Airway Pressure (CPAP)
– One of the most common sleep disorders is sleep
apnea - a disorder that causes a person's airway to
close several times during one night's sleep. For
those with sleep apnea, relief usually comes with
continuous positive airway pressure (CPAP).
Continuous Positive Airway Pressure (CPAP) devices
deliver a prescribed level of positive pressure
non-invasively to the upper airway for the treatment
of sleep apnea. Extremely easy to use, CPAPs come
with different features such as ramping to allow
comfortable adjustment to the pressure; software to
capture specific usage and breathing events; and
automated altitude adjustment. Accessories, such as
nasal interface applications and humidification
devices are provided to afford maximum comfort to
ensure patient compliance.
Cylinders - are available in
various sizes. Carrying cases or carts are used for
the different size tanks.
M2 - Weighs less than 2 pounds and only 7.9 inches
in length, this extremely lightweight, compact
medical oxygen cylinder is the perfect solution for
anyone who needs a convenient, easily transportable
medical oxygen supply for a short amount of time.
This cylinder is the smallest aluminum oxygen
cylinder in the world yet can supply up to 2 hours
of oxygen.
M4 - medical oxygen cylinder is a great solution for
anyone who needs a convenient, easily transportable
medical oxygen supply for a short amount of time.
This cylinder weighs under 3 pounds and is only 12
inches in length. This cylinder can supply up to 7
hours of oxygen.
M6 – extremely popular medical oxygen cylinder is
the perfect balance between portability and oxygen
supply duration. The M6 cylinder is less than 15
inches in length and weighs only 3 pounds and can
supply up to 10 hours of oxygen.
ML6 - Similar to the M6 cylinder, the ML6 is a great
balance between portability and oxygen supply
duration. This cylinder weighs under 4 pounds and is
shorter and wider than the M6 cylinder. This
cylinder can provide up to 10 hours of oxygen.
M9 – a popular cylinder is a great balance between
portability and oxygen supply duration. The M9 is
less than 16 inches in length and weighs only 4.5
pounds yet can supply up to 14 hours of oxygen.
Portable E Tanks - Portable smaller
units called E tanks are used for transport. A key
is required to turn the tank on and off. The
portable tanks must be replaced when empty.
Therefore, the family must plan ahead for trips
outside of the home. Portable E tanks may be used
for backup in case of power failure.
Nebulizer - is a type of inhaler
that provides a fine mist of medication to the
lungs. This is performed by breathing the medicated
mist through a mouthpiece or mask attached to the
nebulizer device, which is driven via a plastic
tubing, attached to the compressor unit. The
medications used in nebulizers help you by loosening
the mucus in the lungs so it can be coughed out more
easily, and by relaxing the airways so that more air
can move in and out of the lungs. Nebulizer
treatments take approximately 15 minutes to deliver
the medication and are prescribed by your physician.
Pediatric Nebulizer - A special
breathing device usually used 3 or 4 times daily as
needed; or as directed by your doctor. It works in
the lungs by opening breathing passages to make
breathing easier. This device is intended for use in
children but may also be used for adults requiring
smaller doses.
Oxygen Concentrators -
electronically powered device with a series of
filters that extract oxygen from room air. Also, a
backup system, usually a stationary compressed gas
system. Must always accompany a concentrator in case
of power failure or other emergency. Regular
household current is sufficient for its use. In
limited cases, a humidifier bottle may be necessary
to increase moisture to the oxygen as it passes
through the tubing to the mask or cannula.
Common Diagnoses:
- Chronic Obstructive pulmonary diseases (COPD)
- Emphysema
- Asthma
- Chronic Bronchitis
- Lung Cancer
- Acute Myocardial Infarction
- Acute Pulmonary Heart Disease
- Congestive Heart Failure
- Viral Pneumonia
- Bacterial Pneumonia
- Bronchlectasis
Oxygen Conservers - are types of
regulators, which conserve the amount of gaseous
oxygen in portable cylinders. Oximetry testing is
required to ensure proper oxygen saturation during
use of a conserver.
Portable Oxygen Systems -
incorporate either the electronic conserving device,
the pneumatic conserving device, or standard flow
regulators. These systems provide individuals with a
convenient, lightweight supply of oxygen. Systems
are available with one or multiple M4, M6, M9, MD,
or ME cylinders, fiber-wrapped cylinders, shoulder,
horizontal, backpack, or fanny pack style carrying
bags, cart, regulator, cannula, and supply tubing.
All systems are also available with a straight post
valve, handtight or a toggle CGA870 valve.
Mobility Products
Canes – adjustable height canes can
improve balance and reduce fatigue. Travel canes can
fold up and be carried in a travel case. Standard
crook canes are lightweight and durable to help
improve balance and reduce fatigue . Quad canes are
used when there is a need for additional stability.
Quad canes have a base with four legs affording
greater stability than straight canes. Quad canes
can be ordered with narrow or wide bases.
Crutches – Standard adjustable
crutches are lightweight and easily adjust to size.
Forearm crutches have contoured arm cuffs for extra
comfort and stability.
Lifts/Seating Systems - Power lift
chairs gently moves the person to a standing,
seating, or reclined position.
Patient Lifts – (power or
hydraulic) for assistance with patient transferring.
Lift/commode is a FDA registered medical device,
ideal for people with musculo-skeletal or
neuromuscular limitations. It is motorized and
designed to operate as a lift system and as an
adjustable height commode. It can be used as a
bedside commode (helps reduce bedpan use) or as a
transfer system to move a person from a bed to a
seated or standing position.
Ramps - portable ramps for
wheelchairs and scooters roll up for easy carrying
with storage bag. Scooter ramps have side rails and
center panels that slide easily into place, locking
securely to provide a solid drive surface. Suitcase
ramps are convenient and compact, fold up easily and
have a built-in carrying handle. Telescopic channel
ramps each extend to be used on steps, vans, or
curbs. For storage, simply pick up each rail and
depress the guide buttons to collapse. Chair lifts
allow you to lift and carry your power chair fully
assembled.
Walkers – are available in a
variety of styles to meet individual needs. Folding,
adjustable walkers can be easily transported in
vehicles. Hemi-walkers allow for one-hand
utilization. Wheeled walkers minimize lifting. Many
accessories, such as walker trays, baskets or
pouches are available.
Disease States:
Hypertension: Blood pressure
greater than or equal to 140/90 mmHg.
COPD: Chronic obstructive pulmonary
disease (COPD) is a catch-all term for a number of
respiratory diseases. The diseases of COPD include
chronic bronchitis, pulmonary emphysema, asthma and
bronchiectasis (a chronic inflammatory or
degenerative condition of one or more bronchi or
bronchioles marked by dilatation and loss of
elasticity of the walls).
Asthma: Hyper-responsive airways
manifested by a narrowing of the airway.
Sleep Apnea: a breathing disorder
characterized by brief interruptions of breathing
during sleep.
-
Central Sleep Apnea: Occurs when the
brain fails to send the appropriate signals
to the breathing muscles to initiate
respirations.
-
Obstructive Sleep Apnea: Occurs when
air cannot flow into or out of the person’s
nose or mouth, although efforts to breath
continue.
Diabetes: Disease in which blood
glucose levels are above normal
-
Type 1 diabetes: diabetes of a form
that usually develops during childhood or
adolescence and is characterized by a severe
deficiency of insulin secretion resulting
from atrophy of the islets of Langerhans and
causing hyperglycemia and a marked tendency
toward ketoacidosis -- called also
insulin-dependent diabetes,
insulin-dependent diabetes mellitus,
juvenile diabetes, juvenile-onset diabetes,
type 1 diabetes mellitus
-
Type 2 diabetes: a common form that
develops especially in adults and most often
in obese individuals and that is
characterized by hyperglycemia resulting
from impaired insulin utilization coupled
with the body's inability to compensate with
increased insulin production -- called
also adult-onset diabetes, late-onset
diabetes, maturity-onset diabetes,
non-insulin-dependent diabetes,
non-insulin-dependent diabetes mellitus,
type 2 diabetes mellitus
CHF: heart failure in which the
heart is unable to maintain adequate circulation of
blood in the tissues of the body or to pump out the
venous blood returned to it by the venous
circulation
Urinary Incontinence: Incontinence
is the inability to control the passage of urine.
This can range from an occasional leakage of urine,
to a complete inability to hold any urine. Urinary
incontinence affects approximately 13 million people
in the United States and is more common in women
than in men. It occurs in 10 percent to 25 percent
of women younger than age 65 and in 15 percent to 30
percent of women older than age 60 who do not live
in nursing homes. Among nursing home residents,
incontinence is even more common, affecting more
than 50 percent of female patients.
Cystic Fibrosis (CF): a
life-threatening disorder that causes severe lung
damage and nutritional deficiencies. CF is an
inherited (genetic) condition affecting the cells
that produce mucus, sweat, saliva and digestive
juices. Normally, these secretions are thin and
slippery, but in CF, a defective gene causes the
secretions to become thick and sticky. Instead of
acting as a lubricant, the secretions plug up tubes,
ducts and passageways, especially in the pancreas
and lungs. Respiratory failure is the most dangerous
consequence of CF. Each year approximately 3,200
white babies are born in the United States with CF.
The disease is much less common among black and
Asian-American children. Most babies born with CF
are diagnosed by age 3, although mild forms of the
disease may not be detected until the third, fourth
or fifth decade of life. In all, about 30,000
American adults and children are living with the
disorder. Although there's still no cure, the
emerging field of gene therapy may someday help
correct lung problems in people with CF.
Hepatitis C HCV (Hepatitis C Virus):
is an inflammation of the liver causing soreness and
swelling. It is the most common chronic blood borne
infection in the United States. The hepatitis C
virus usually is transmitted through contact with
infected blood, most commonly by sharing needles
during intravenous drug use, or getting a blood
transfusion before 1992. Hepatitis C also may be
spread through unprotected sexual intercourse, but
this is uncommon. Most people don't feel sick when
they are first infected with hepatitis C. Instead,
the virus stays in their liver and causes chronic
liver inflammation.
Multiple Sclerosis: is a chronic,
potentially debilitating disease that affects your
brain and spinal cord (central nervous system). The
illness is probably an autoimmune disease, which
means your immune system responds as if part of your
body is a foreign substance.In MS, your body directs
antibodies and white blood cells against proteins in
the myelin sheath surrounding nerves in your brain
and spinal cord. This causes inflammation and injury
to the sheath and ultimately to your nerves. The
result may be multiple areas of scarring
(sclerosis). The damage slows or blocks muscle
coordination, visual sensation and other nerve
signals.The disease varies in severity, ranging from
a mild illness to one that results in permanent
disability. Treatments can modify the course of the
disease and relieve symptoms.An estimated 400,000
Americans have MS. It generally first occurs in
people between the ages of 20 and 50. The disease is
twice as common in women as in men.
Muscular Dystrophy: is a group of
rare inherited muscle diseases in which muscle
fibers are unusually susceptible to damage. Muscles,
primarily your voluntary muscles, become
progressively weaker. In the late stages of muscular
dystrophy, fat and connective tissue often replace
muscle fibers. In some types of muscular dystrophy,
heart muscles, other involuntary muscles and other
organs are affected. There are many forms of
muscular dystrophy, some noticeable at birth
(congenital muscular dystrophy), others in
adolescence (Becker MD), but the 3 most common types
are Duchenne, facioscapulohumeral, and myotonic. The
various types of the disease affect more than 50,000
Americans. There's no cure, but medications and
therapy can slow the course of the disease.
Osteoporosis: is a disease in which
the density and quality of bone are reduced, leading
to weakness of the skeleton and increased risk of
fracture, particularly of the spine, wrist, hip,
pelvis and upper arm. Osteoporosis and associated
fractures are an important cause of mortality and
morbidity.
In many affected people, bone loss is gradual and
without warning signs until the disease is advanced.
Osteoporosis is also known as "the silent crippler"
because a person usually doesn't know they have it
until it's too late. Unfortunately, in many cases,
the first real "symptom" is a broken bone. Loss of
height – with gradual curvature of the back (caused
by vertebral compression fractures) may be the only
physical sign of osteoporosis.
In the United States, osteoporosis causes more than
1.5 million fractures every year — most of them in
the spine, hip or wrist. And although it's often
thought of as a women's disease, osteoporosis
affects many men as well. About 8 million American
women and 2 million American men have osteoporosis,
and nearly 18 million more Americans may have low
bone density. Even children aren't immune.
Parkinson's Disease: Parkinson's
disease belongs to a group of conditions called
movement disorders. It is both chronic, meaning it
persists over a long period of time, and
progressive, meaning its symptoms grow worse over
time.
Parkinson's disease occurs when a group of cells, in
an area of the brain called the substantia nigra,
that produce a chemical called dopamine begin to
malfunction and eventually die. Dopamine is a
neurotransmitter, or chemical messenger, that
transports signals to the parts of the brain that
control movement initiation and coordination. When
Parkinson's disease occurs, for unexplained reasons,
these cells begin to die at a faster rate and the
amount of dopamine produced in the brain decreases.
The four primary symptoms are:
-
tremor of the hands, arms, legs, jaw, and face;
-
rigidity or stiffness of the limbs and trunk;
-
bradykinesia or slowness of movement, and
-
postural instability or impaired balance and
coordination.
Wheelchairs and Components:
Manual Wheelchairs
Lightweight/Sports Chairs - The
most popular type of wheelchair for everyday use for
a person with good upper body mobility is the
lightweight manual wheelchair. Lightweight chairs
provide maximum independence of movement with a
minimum of effort. Many active wheelchair users also
prefer the sportier look of the lightweights
compared with the more standard looking everyday
chair. It should be noted, however, that heavy or
obese persons may be unable to use these types of
chairs because the lighter weight of the frame
results in a reduced user capacity as compared to
standard everyday chairs. Once used primarily by
wheelchair athletes, the lightweight chair today is
used by people in virtually all walks of life as a
preferred mode of assisted mobility. Three-wheeled
chairs, also developed for such sports as tennis and
basketball, are also an everyday chair alternative.
Standard/Everyday Chairs - Some
wheelchair users still prefer or require a standard
wheelchair, which is characterized by a cross-brace
frame, built-in or removable arm rests, swing-away
footrests, a mid- to high-level back, and push
handles to allow non-occupants to propel the chair.
Child/Junior Chairs - Children and
young adults need chairs that can accommodate their
changing needs as they grow. In addition, it is
important that wheelchairs for children or teens be
adaptable to classroom environments and be "friendly
looking" to help the user fit more readily into
social situations. Manufacturers today are becoming
increasingly sensitive to these market demands and
are attempting to address them with innovative chair
designs and a variety of "kid-oriented" colors and
styles.
Specialty Chairs - Because of the
diverse needs of wheelchair users, wheelchairs have
been designed to accommodate many lifestyles and
user needs. Hemi chairs, which are lower to the
floor than standard chairs, allow the user to propel
the chair using leg strength. Chairs that can be
propelled by one hand are available for people who
have paralysis on one side. Oversized chairs and
chairs designed to accommodate the weight of obese
people are also offered. Rugged, specially equipped
chairs are available for outdoor activities.
Aerodynamic three-wheeled racing chairs are used in
marathons and other racing events. Manual chairs
that raise the user to a standing position are
available for people who need to be able to stand at
their jobs, or who want to stand as part of their
physical conditioning routine. These and other
specialized chair designs generally are manufactured
by independent wheelchair manufacturers who are
trying to meet the needs of specific target markets.
Institutional/Nursing Home/Depot Chair -
The least expensive type of chair
available, an institutional chair, is designed for
institutional usage only, such as transporting
patients in hospitals or nursing homes. It is not an
appropriate alternative for anyone who requires
independent movement, as the institutional chair is
not fitted for a specific individual. These types of
chairs are now also used as rental chairs and by
commercial enterprises (such as grocery stores and
airports) for temporary use.
Manual Wheelchair Components
Frame - The two most common types
of frames currently available are rigid frame chairs
(where the frame remains in one piece and the wheels
are released for storage or travel), and the
standard cross-brace frame (which enables the frame
to fold for transport or storage).
Upholstery - must withstand daily
use in all kinds of weather. Consequently,
manufacturers provide a variety of options to users,
ranging from cloth to new synthetic fabrics to
leather. Many manufacturers also offer a selection
of upholstery colors, ranging from black to neon, to
allow for individual selection and differing tastes
among consumers.
Seating System - are sold
separately from the wheelchairs themselves, as
seating must be chosen on an individual basis. It is
important when selecting a wheelchair or a seating
system to ensure that the two components are
compatible.
Brakes – or wheel locks are
available in several different designs, and can be
mounted at various heights to maximize convenience
to the user.
Wheels/Tire - Most wheelchairs use
four wheels, with two large wheels at the back and
two smaller ones (casters) at the front. The
standard tire used for the rear wheels on most
wheelchairs is a pneumatic tire, for which the
standard size is 24 inches. Smaller and larger
sizes, however, also are available. Many
manufacturers now also offer other types of
tires--such as solid tires, semi-pneumatic, or
radial tires--at extra cost. Mag wheels and off road
wheels also are options on some chairs. Casters,
too, vary in size (ranging from six to eight inches
in diameter) and composition (pneumatic, solid
rubber, plastic, or a combination of these).
Footrests - usually are
incorporated into the frame of the chair as part of
the design. Cross-brace folding chairs often have
footrests which swivel, flip up, and/or can be
removed.
Armrests - Many lightweight manual
chairs are designed to be used without armrests.
The absence of armrests makes it easier for the user
to roll up to a desk or table, and many active
wheelchair users prefer the streamlined look of a
chair with no armrests. However, armrests are
helpful if the user has difficulty with upper body
balance while seated. Armrests come in a variety of
styles including desk length (to allow the user
closer access to desks and tables) or full length
and both types may be flip-up, fixed, or detachable.
Powered Wheelchairs
A
powered wheelchair must be selected carefully in
order to ensure it not only meets the needs of the
individual who will use it but also represents good
value for the money being invested in it. Physical
considerations include posture, strength, sensation,
visual acuity and perception, and the ability to
learn how to use the wheelchair safely. A functional
evaluation should include actual use of the
wheelchair in everyday settings; an evaluation of
the individual's ability to get in and out of the
wheelchair; and the ability to perform needed
activities from the wheelchair. Transportation to
and from various settings also is an important
consideration: Is a van available to transport the
individual in the chair, or is it necessary for the
chair to fold or disassemble in order to be carried
in an automobile trunk?
Powered Wheelchair Components
Frames - Many traditional-style
models utilize the traditional cross-brace frame
which allows the chair to be folded or collapsed for
storage and transport once the batteries have been
removed. Other traditional models and some power
base chairs disassemble for transport. A number of
chairs, however, are designed to be transported
while carrying the user; consequently, they do not
fold or disassemble.
Upholstery - for wheelchairs must
withstand daily use in all kinds of weather.
Consequently, manufacturers provide a variety of
options to users, ranging from cloth to new
synthetic fabrics to leather. Many manufacturers
also offer a selection of upholstery colors, ranging
from black to neon, to allow for individual
selection and differing tastes among consumers.
Seating System - are sold
separately from the wheelchairs themselves, as
seating must be chosen on an individual basis. It is
important when selecting a wheelchair or a seating
system to ensure that the two components are
compatible. Power base chairs, because of their more
modular construction, frequently feature customized
chair-style seating systems.
Brakes - Most powered chairs
utilize a dynamic braking system in which the motor
and brakes work together to slow and stop the chair
when the joystick or other controller is released,
and which automatically engages the brakes when the
power is off or when the chair is not being powered
in a forward or reverse motion with the controller.
Wheels/Tires - Power base chairs
typically use four wheels of the same size, usually
8 to 10 inches in diameter. These chairs may have
pneumatic, semi-pneumatic, or solid tires.
Footrests - A variety of footrest
assemblies are available on both types of
wheelchairs. They may be a rigid single unit, 90
degree-90 degree platforms, folding, flip-up,
detachable, adjustable length, hemi- height, or have
a combination of features.
Armrests - Armrests also come in
several styles or with a combination of features.
They may be full- or desk-length, or wraparound, and
they may be fixed, removable, pivoting, and/or
adjustable height.
Controls - Powered chairs generally
include as a standard feature a manually controlled
joystick to regulate the chair's speed and
direction. However, most manufacturers offer
customized control options to accommodate the varied
abilities of the user, including sip-n-puff systems,
head and chin switches, push-button controls,
trackballs, and tillers. Many chairs also have
programmable control features which allow the user
or a dealer to adjust or set the chair's speed and
control limits as the user's abilities change.
Drive System - the means by which
power is delivered to the chair's wheels. Standard
drive systems include gear drive, direct drive, and
belt drive. The type of drive system affects the
power available to propel the chair and the amount
and type of maintenance the chair requires.
Batteries - are a determining
factor in the range and power of a powered chair.
Generally, the larger the chair's batteries, the
greater the power and the longer the chair's range
between charges. Many chairs require two
rechargeable 12-volt batteries. Most wheelchairs
utilize U1, group 22 or 24 batteries, although other
batteries are also used. More manufacturers are
designing chairs around the group 24 battery because
it affords a longer range. The type of battery
required is also an important consideration in terms
of safety, maintenance, and transport. Powered
chairs may utilize lead acid, gel cell, or sealed
wet batteries. Gel cell batteries require the least
maintenance and have less danger of leaking than do
the other battery types. Gel cell batteries are also
required by a number of airlines when transporting
powered
chairs.
Special Powered Features - Powered
chairs may offer specialized powered features to
meet the user's needs, either as customization or
options on a standard chair or as a chair designed
specifically for a particular purpose. Among the
available features are elevating and lowering seats,
and reclining and/or tilt-in-space seats.
Specialized chairs have the capacity to raise the
user to a standing position, to negotiate stairs, or
to be used as a lift or in transferring.
Scooters
Typically, scooter users have some ability to walk,
but are limited in distance or stamina--people with
milder forms of cerebral palsy, multiple sclerosis,
post-polio syndrome, stroke survivors, arthritis,
and cardiac conditions, among others. Scooters are
used to increase and extend the range of personal
mobility and help conserve energy. Scooter users
often have difficulty propelling manual wheelchairs,
but do not require the sophisticated electronic
controls and seating systems common in powered
wheelchairs.
A
number of other physical factors must also be
evaluated when determining whether a scooter is an
appropriate mobility aid. A scooter user generally
must be able to sit upright for extended periods and
have sufficient seated balance to maintain an erect
posture. Further, sufficient upper body and arm
strength to master the controls and steer and
maneuver the unit is required. In addition,
uncorrected vision disabilities, or conditions which
may cause confusion or memory loss or which inhibit
proper safety awareness may render a scooter an
unsatisfactory mobility aid.
Scooter Configurations and Components
Base Unit - is basically the body
of the scooter. Generally it consists of a steel,
aluminum, or composite frame with a fiberglass or
composite floor to support the feet and batteries.
Some scooter bases also include a shroud over the
front wheel and drive head, creating a dashboard for
the unit. The base also includes the wheels and the
drive train. In some scooters, the seat post is also
part of the base. The base unit is the primary
determinant of whether the scooter is designed for
indoor or outdoor use, the vehicle's
maneuverability, the size of its wheelbase, its
ground clearance, its turning radius, and its
overall dimensions.
A
scooter should not tip easily during sharp turns or
on inclines such as curb cuts (if the scooter is
designed for outdoor use). Anti-tip wheels should
be included as part of the frame to help support and
stabilize the scooter. On front-wheel drive units,
anti- tips are often located laterally just behind
the front wheel because they generally lack the
power for steep inclines. Because most rear-wheel
drive scooters are intended to negotiate more rugged
terrain, they are usually equipped with rear
anti-tips to support the scooter on hills. Side
anti-tip wheels are sometimes offered as options. It
should be noted that lateral anti-tippers may cause
difficulties on curb cuts and ramps.
On some scooters, the base unit may be comprised of
modular units or may otherwise be disassembled for
transport and storage. These same features may also
allow the scooter to be converted from three- to
four-wheeled models and/or from indoor to outdoor
use.
Drive Train, Brakes, and Power System -
The drive train is an integral part of the base unit
and provides either front- or rear- wheel drive for
the scooter. Front-wheel drive is usually found on
smaller scooters designed primarily to be used
indoors or outdoors on flat, paved surfaces. The
motor of the front-wheel drive scooter is located
over the front wheel and drives only that wheel.
Because of the motor and wheel configuration,
front-wheel drive scooters are usually direct-drive
units, eliminating chains and belts. However, this
also means that the front wheel pulls the weight of
the unit and the rider. Consequently, these types of
scooters have a lesser capacity to move their load
than do rear-wheel drive models, and are therefore
less capable of handling hills, curb cuts, and other
outdoor terrain. This is compounded by the fact that
front-wheel drive models generally have smaller
motors, causing them to have a shorter range, less
speed and power, and a smaller rider weight
capacity.
Rear-wheel drive scooters are powered by motors
connected to the rear axle, either via a chain, a
belt, a transaxle unit, or some combination.
Because the scooter is driven by the rear wheels,
they push the combined weight of the unit and the
rider, rather than pull it. The combined weight of
the rider, the motor, and the batteries over the
rear wheels, generally create better traction than
that usually provided by front-wheel drive models.
The increased traction combined with the more
powerful motors used on rear-wheel drive scooters
results in better climbing ability. The units also
have a greater maximum speed, a longer travelling
range between battery charges, and a larger rider
weight capacity. These scooters have a wider wheel
base and a greater overall length, making them less
maneuverable and rendering some models unsuitable
for indoor use. They may also be too large for van
or bus lifts.
Brakes - most rear-wheel drive
scooters utilize an electronic or elctro-mechanical
dynamic, regenerative braking system. This type of
braking system works in tandem with the motor, first
to slow and then stop the vehicle when the pressure
is released on the thumb levers or the controls are
otherwise disengaged. When the scooter is not being
powered forward or in reverse, the brakes are
engaged, thus preventing the scooter from moving.
During the application of the brakes, excess power
from the motor is channeled to the batteries,
providing recharging. Because the brakes are engaged
when the scooter is being actively powered, most
scooters with this braking system are equipped with
a clutch on the motor or another release lever to
manually disengage the brakes to allow the scooter
to be pushed in case of emergency.
Some scooters also use disc brakes or disc brakes in
combination with the braking system discussed above.
Some scooters--usually front-wheel drive models--are
not equipped with electronic or electro-mechanical
brakes. In the absence of a brake system, a manual
parking brake applied by lever to a rear wheel is
provided. Manual parking brakes may also be offered
either as optional or standard features on other
scooters to provide extra braking on hills and
inclines.
Batteries - most scooters utilize
12- or 24-volt motors and electrical systems
generally with one or two 12-volt batteries to power
the drive train and controls. Twelve-volt systems
are most frequently found on front-wheel drive
scooters, and usually require one 12-volt battery,
although two six-volt batteries are sometime used.
Some manufacturers offer add-on units for 12-volt
systems which allow them to utilize two batteries to
extend the scooter's range between charges, although
speed and power are not affected. Rear-wheel drive
systems generally require two twelve-volt batteries
to power 24-volt systems.
These batteries are "deep cycle" batteries intended
for wheelchairs and scooters and generally last
between 12 and 18 months, although with conservation
and regular charging, longer life may be achieved.
Deep cycle batteries are designed to provide a
steady supply of power and be discharged and
recharged on a regular basis. Automotive and marine
batteries, on the other hand, are designed to be
starter batteries, providing short bursts of power
only. Consequently, marine and automotive batteries
should never be substituted for deep cycle
batteries.
There are three basic types available for use with
scooters: Lead acid (or wet cell) batteries, sealed
lead-acid batteries, and gel cell batteries. Lead
acid batteries are the least expensive of the three
types, but they also require the most maintenance.
In addition to regular charging, electrolyte and
water levels must be checked regularly, with water
added frequently to maintain appropriate levels.
Because these batteries are not sealed, there is
danger of acid spillage and explosion if the
batteries are not handled properly. Despite these
potential problems, lead-acid batteries provide the
benefits of a two- to six-month longer battery life
and up to a ten percent greater running time than
other battery types. Sealed lead acid batteries
are maintenance-free versions of these batteries.
Because they are sealed in cases, it is unnecessary
to add water and the danger of acid spillage is
reduced or eliminated. The cases are vented to
prevent gas build-up that can lead to an explosion.
Finally, gel cell batteries are the most commonly
used battery type on scooters. They are sealed in
their cases and require no maintenance other than
regular charging. Gel cells are the safest of the
battery types, with no danger of spillage and
limited risk of explosion. However, gel cells are
more expensive, and may have a somewhat shorter life
than other battery types.
Wheels and Tires - The size of the
wheels and tires on a scooter have a direct affect
on the scooter's ability to surmount obstacles and
its stability. Scooters are generally equipped with
six-, eight-, or ten-inch wheels, although other
sizes may also be used. Some models use the same
size wheels both front and rear, while others may
have smaller wheels in front and larger rear wheels.
Smaller wheels are generally found on front-wheel
drive scooters intended for indoor use. As a rule,
the intended use of the scooter should dictate the
size of the wheels and tires. The larger the wheels,
the more stable the unit. Similarly the larger and
wider the tires, the greater the unit's traction and
capacity to manage such obstacles as curb cuts and
uneven outdoor terrain.
Several types of tires are available for scooters.
Manufacturers generally offer a specific tire as
standard equipment, with others available as
extra-cost options. Pneumatic tires include
air-filled tubes and are similar to those found on
automobiles. Air pressure should be checked
regularly to maintain proper levels, and tires may
need to be replaced if punctured. The addition of an
anti-flat compound before inflation reduces the risk
of tires going flat. They provide good shock
absorption when properly inflated. Foam filled tires
are similar to pneumatic tires, but include foam
inserts rather than air-filled tubes. These tires
cannot be deflated and, therefore, require less
maintenance. They may be more expensive than
pneumatic tires and may not offer a consistently
comfortable ride. The least expensive tire option is
the solid rubber tire. These tires require the least
maintenance, but provide minimal shock absorption
and are intended primarily for indoor use.
Seating - The most common seat
found on scooters is a chair-style seat similar to
those found on boats. The basic seat is molded hard
plastic or fiberglass, but most manufacturers offer
a padded-seat option, usually with a choice of vinyl
or fabric upholstery. Vinyl upholstery is frequently
less expensive, but because it is a slipperier
surface, it may not be the best choice for those
whose disability makes it difficult to maintain
position or balance.
Armrests - are another
consideration in seating. Some scooters offer
armrests only as an option; others offer fixed
armrests as standard with flip-up armrests
available.
Tiller - The control and steering
mechanism for the scooter, usually containing the
controls to drive the scooter forward or in reverse,
as well as steering the front wheel or wheels. Most
scooters offer one type of standard tiller with
other controllers available as options.
Possibilities include thumb levers, loop handles,
joysticks, and others. Thumb levers are the most
common controls, allowing the user to keep both
hands on the handle bars while using the left thumb
to power the scooter in reverse and the right to
power the scooter forward. The amount of pressure
applied to the lever will determine the speed of the
vehicle (unless it is equipped with a proportional
speed control). Consequently, a fair amount of hand
control is necessary for safe operation. Finger
control levers or a joystick may be alternatives.
Some manufacturers may also be able to adapt
controls to user requirements at extra cost.
The tiller itself is often an upright post attached
to the front wheel. However, it is also becoming
common to find flexible, accordion-style tillers
which can be adjusted for height and/or position.
This not only enables the user to place the tiller
in the most comfortable position while driving, but
also allows it to be moved up and out of the way
during transfers. In the absence of a dashboard or
shroud over the front wheel, a control box with the
key lock, battery level indicator, speed controller,
and other features may be
affixed to the tiller handlebars.
Since a joystick controls both speed and direction,
scooters equipped with them generally do not have
the post-and-handlebar tiller; the joystick is
usually attached to an armrest or to an armrest
extension, with a choice of right or left mounting.
While this frees the space in front of the user and
may accommodate easier transitions for some, the
lack of handlebars may make transfers more difficult
for others.
Other Accessories - In addition to
the standard features common to all scooters
discussed above, manufacturers offer a variety of
standard features and optional accessories. Most
scooters are equipped with a key lock for turning
the scooter on and off, thus conserving battery life
and preventing unauthorized use; a battery-level
indicator and a proportional speed controller to
limit maximum speed.
A
wide range of accessories also are offered on most
scooters, such as crutch and cane holders, oxygen
carriers, front and rear baskets, trailers,
headlights, tail lights, horns, canopies, and
others. Some manufacturers even offer sidecars to
allow an additional passenger. As when purchasing a
car, options and additional features increase the
base cost of the unit, but accessories should be
evaluated in light of their capacity to create a
mobility aid which provides maximum user
independence. At the same time, it should be kept in
mind that some options may decrease battery life,
maneuverability, and/or travel range.
Other Home Medical Equipment
Bariatric products are designed to
have a weight capacity of 300 pounds (or more) for
those who need that extra support. Bariatric chairs
maximize the patient's ability to sit and stand with
reduced effort, and lessens the chance of lifting
injury to the caregiver.
Bariatric beds have extra bracing integrated into
the home care bed frame, along with a wider surface
and truss assembly, in order to provide maximum
support.
Portable lifting cushions -
provide that extra lift needed to help you get in
and out of any armchair on your own by shifting your
weight forward and pushing off gently with your arms
and/or legs. The pneumatic lift will help to gently
raise you up to an almost standing position. The
cushion is portable and weighs approximately 9
pounds and flattens quickly for easy transport.
Commodes - 3 in 1 Commodes are
adjustable and include back, pail w/lid, toilet seat
and cover. Some can be used as a free standing
commode or a raised toilet seat. Lift/commode is a
FDA registered medical device, ideal for people with
musculo-skeletal or neuromuscular limitations. It is
motorized and designed to operate as a lift system
and as an adjustable height commode. It can be used
as a bedside commode (helps reduce bedpan use) or as
a transfer system to move a person from a bed to a
seated or standing position.
Compression Stockings -
Problems with the veins of the leg occur in both men
and women of all ages but certain factors increase
the risk of venous problems. Health conditions,
lifestyle habits, heredity, injury, surgery, age,
and pregnancy all play a role. A broad range of
compression hosiery from knee, thigh high, waist
chaps, open and closed toe are manufactured to meet
your needs. For more information:

Continuous Passive Motion (CPM) -
devices are available for synovial joints (hip,
knee, ankle, shoulder, elbow, wrist, and TMJ)
following surgery or trauma (including fracture,
infection, etc). The device moves the affected joint
continuously on a 24-hour basis, without patient
assistance. The device is held in place across the
affected joint by Velcro straps. An electrical power
unit is used to set the variable range of motion and
speed. The speed and range of motion can be adjusted
depending on joint stability, patient comfort level,
and other factors assessed intraoperatively.
Diabetic Supplies – Blood glucose
monitoring – there are a variety of systems
available that allow testing on arms, fingers or
thighs, with fast and accurate results and minimal
cleaning required.
Environmental Control Units -
permits remote
control of electronic devices in the immediate
surroundings. A person can independently turn
lights, radio, and television on and off, answer or
initiate phone calls, and unlock a door. Essentially
any aspect of the environment can be controlled
depending upon the system's complexity. For more
information and products:

Hospital Beds - allow for
positioning and safety, not possible with standard
beds. There are basically three (3) types of
hospital beds available for home use: Semi-Electric
Beds – allows for raising and lowering the head and
the knee break through the use of an automatic
hand-held control. Raising the entire bed height is
accomplished through use of a manual crank. Manual
Beds – allows for raising and lowering the head of
the bed and the knee break, through the use of a
manual crank. Full or half-side rails are available.
Full-Electric Beds – allows for the raising and
lowering functions of the head and knee break, along
with the entire bed height adjustment is operated by
a hand-held control.
T.E.N.S. dual channel units – a
transcutaneous electro-nerve stimulator; pain
control that goes where you do. A small medical
device slightly larger than a beeper, attaches to
your pants or belt and helps alleviate pain while
you wear it.
T.E.N.S. units have been dispensed
by doctors to their patients for home use. They
operate on a 9v. transistor battery and have small
wires and pads that adhere to a painful area and
alleviate pain. Tiny free nerve endings secrete a
chemical called "substance P" that transmits pain
signals to our brain. T.E.N.S. units artificially
stimulate free nerve endings, thereby depleting them
of substance P, literally stopping the pain signal
in its tracks.
Wound V.A.C Therapy -
or negative pressure wound therapy uses negative
pressure through a controlled suction device to
close large wounds and promote faster healing. This
patented, FDA-approved device is composed of a
sophisticated pump, hoses and monitoring system held
within a portable compact case weighing less than 20
pounds. It is recognized as an advanced line therapy
alternative for patients where traditional dressing
changes are not effective. It is a method that is
considered among recovering patients in hospitals,
nursing homes and other home health care settings.
It meets the needs of most cost-effective modalities
and an estimated 5 million American patients
suffering from chronic or acute wounds.

Ostomy Supplies – Pouching system
s- may include a one-piece or two-piece system. Both
kinds include a faceplate/flange (barrier or wafer)
and a collection pouch. The pouch (one-piece or
two-piece) attaches to the abdomen by the
faceplate/flange and is fitted over and around the
stoma to collect the diverted output, either stool
or urine. The barrier is designed to protect the
skin from the stoma output and to be as neutral to
the skin as possible
-
One-piece pouching system - the ostomy pouch and
skin barrier are joined together permanently. The
pouch and skin barrier are applied and removed
together—in one piece. Easy to apply and remove and
more flexible than a two-piece pouching system.
-
Two-piece pouching system, the ostomy pouch and skin
barrier are separate . The pouch can be removed
without removing the skin barrier. Because it is
separate from the pouch, the skin barrier can be
more easily positioned around the stoma.
Pediatric pouching systems are available as either
one-piece products or two-piece products and are
designed for premature babies, infants, and
children. These systems can also be used to manage
adult conditions such as small wounds, drain sites,
and fistulas. Irrigation systems - Some colostomates
can "irrigate," using a procedure analogous to an
enema. This is done to clean stool directly out of
the colon through the stoma. This requires a special
irrigation system, consisting of an irrigation bag
with a connecting tube (or catheter), a stoma cone
and an irrigation sleeve. A special lubricant is
sometimes used on the stoma in preparation for
irrigation. Following irrigation, some colostomates
can use a stoma cap, a one- or two-piece system
which simply covers and protects the stoma. This
procedure is usually done to avoid the need to wear
a pouch.
Urinary pouching systems -
urostomates can use either one or two piece systems.
However, these systems also contain a special valve
or spout which adapts to either a leg bag or to a
night drain tube connecting to a special drainable
bag or bottle.
