Shopping For an Electric Powered Wheelchair
A wheelchair powered by electricity can be very beneficial for individuals who have a limited mobility. These chairs are available at specialty mobility equipment suppliers and a few major retailers. Medicare and private insurance can cover the cost of an electrical wheelchair if a physician deems it medically essential.
Most power wheelchairs come with a joystick that users can use to control the motors. These movements are converted to electrical signals by a controller that acts like the brain of the chair.
Battery Life
When shopping for a power wheelchair one of the most important aspects to consider is battery life. A good battery can last for two years with regular use and proper maintenance. The battery type also influences the distance that wheelchairs can travel on one charge.
The majority of power wheelchairs utilize deep cycle batteries that are designed to last for a long time and provide a steady energy supply. They can handle a variety of recharges and discharges without causing damage battery cells. It is important to follow the recommendations of the manufacturer for charging, which typically include overnight charging of the battery and avoiding allowing it to run completely empty.
The battery life is also affected by the surface of the wheelchair. Smooth, level surfaces require less energy to propel the chair, leading to longer battery life. If a wheelchair is driven over rough or bumpy terrain, the motors need to work harder in order to maintain speed and balance which takes energy and drains batteries faster.
The condition of a battery and its usage pattern can also affect its longevity. If a battery is getting old and is losing its capacity to keep the charge, it might be time for a replacement. A newer battery will cut down on the time it takes to charge a wheelchair and is likely to be more powerful.
Wheelchair batteries are available in several sizes including Group 22NF and Group 24 being the most popular options. Group 22NF batteries are lighter and smaller than Group 24 batteries, helping to decrease the overall weight and size of a power wheelchair. These batteries have a smaller power reserve or "juice" than Group 24 batteries.
Avoid charging or subcharging the battery, as this can reduce its life. The battery should be kept in a dry, cool place is also important since exposure to extreme temperatures could affect the battery's performance.
Capacity for Weight
Weight capacity is a key aspect to take into account when selecting the best power wheelchair. If the chair is used on long trips the chair must be able to support the user's weight. Weight issues can result from excessive weight, which can also lead to accidents and battery life issues.
The weight of a power chair varies between models and is affected by the batteries it uses. It also affects the variety and types of accessories it has such as oxygen tank holders and various seating systems. The batteries account for the bulk of its weight. One battery can weigh up to 50 lbs alone, and a power chair typically has two batteries!
Whether the power wheelchair has two-pole or four-pole motor can also affect the weight of the wheelchair. A four-pole power chair is more efficient and has more weight capacity. However, it requires more energy and drain batteries faster than a motor with just two poles.
Power wheelchairs can also have different drive bases, such as mid-wheel or rear-wheel. The position of the drive wheels may affect the maneuverability and handling of the wheelchair in a variety of conditions. The drive base can also contain a variety of options, including an adjustable swing-away control that assists with side-transfers or sip-and puff controls that work by blowing air on the sensor.
Another consideration is the environment that the power wheelchair is employed. It's essential that the chair can travel across a variety of terrains and be able to fit into rooms and hallways. It is crucial to measure the doorways, and make sure that the chair will pass through them. This includes hinged doors.
A physical therapist and/or mobility specialist can assist in selecting the appropriate power wheelchair for your needs. They can offer advice on aspects like comfort, accessibility changes as well as the size of the seat and the weight of the wheelchair. They will also look at the frequency and duration, and whether the chair will be moved frequently.
Seating
Electric wheelchairs come with motors that move them, in contrast to manual wheelchairs. This allows you to move more easily and farther than a manual one, however, there are a few limitations.
First, you'll need to be aware of the weight capacity of your new power chair. You should never exceed the recommended weight limit, regardless of whether it's you or any other equipment or items that you're carrying.
Then, ensure that your power chair has a comfortable seat and an appropriate footplate that you are able to fit into. If you don't have enough space for your feet to rest on the footplate, it may shift your center of gravity backward and cause the wheelchair to slouch.
Also, consider a power wheelchair with tilt and recline capabilities to help reduce the chance of developing pressure sores. This feature is essential for those who are elderly and whose skin may be thin and bruises easily. Power leg rests are also an excellent way to raise your legs, which will reduce swelling.
Like any other mechanical device it will require maintenance to ensure that it performs well and safely. You'll need to inspect the battery, tire pressure, brakes, and other parts of your device regularly. You should also check the seating for wear, and make any adjustments that are needed.
It is essential to keep your electric chair in a location that will not expose it to extreme weather conditions. Exposed to extreme temperatures could degrade the frame, while exposure to low temperatures could damage the battery and other electrical components.
Unless you're buying the wheelchair out of pocket it isn't insured and you won't be able return it if it doesn't satisfy your needs. Manufacturer warranties typically last one to two years and cover motors, electronics, joysticks and frames, but not the seats, back cushions or tires. Before purchasing an electric wheelchair, you should inquire with your dealer about their return policy. In the first place, review the user's manual thoroughly and follow all the directions for using and maintaining the device.
Operation
Power wheelchairs are driven by a motor in the power base, which sits beneath the seat of the user. The motor is powered by two 12-volt rechargeable batteries connected in series to produce a total voltage of 24 volts. LITH-TECH provides lithium batteries that are more efficient in energy than lead acids and can be used over a longer period of time.
The controller, electronics and power base can be modified to meet the needs of various users, with numerous options available. Certain chairs offer adjustable seating, which will ensure a comfortable fit. compact electric wheelchair uk allows the user to choose the ideal position that allows them to maintain their postural stability. Many models also include adjustable heights for the seat as well as recline and leg rest positions as well as power tilt functionality.
Electric powered wheelchairs can be equipped with a range of accessories. These include oxygen tank holders, elevating chairs and a wide range of power accessories. Some powerchairs are customised to allow the user to control them with their brainwaves or nerve signals.
Certain powerchairs are able to alter the speed according to the preferences of the user or to be synchronized with other vehicles on the road. For instance when driving uphill. Certain powerchairs come with sensors that warn them of dangers or obstacles close by, and they automatically slow down and stop when necessary.
The position of the drive wheels, whether they are rear-wheels, mid-wheels or front-wheel drives has significant impact on the performance of a chair under different conditions. This is a massive issue, so we'll leave it for a later Clinical Corner.
Check that your new electric chair is fully charged and the tires are at the correct pressure prior to taking it for a spin. In preparation for your first time, it's a good idea make some adjustments to your chair, armrests and footrests. Be sure to adhere to the instructions in the manual for operating your wheelchair, especially when driving down and up slopes. This will lower the risk of discomfort and injuries.
