Shopping For an Electric Powered Wheelchair
A wheelchair powered by electricity can be very beneficial for individuals with mobility issues. These chairs are available at specialty mobility equipment suppliers and some major retailers. Medicare and private insurance may pay for an electric wheelchair if considered medically necessary by a doctor.
The majority of power wheelchairs come with a joystick, which users can use to control the motors. These movements are converted to electrical signals by a controller that functions as a brain for the chair.
Battery Life
When looking for a power wheelchair one of the most important factors to take into consideration is the battery's lifespan. A high-quality battery will last for up to two years with regular usage and proper maintenance. The type of battery can also influence the distance a wheelchair can travel on one charge.
The majority of power wheelchairs have deep cycle batteries, which are designed to provide a long-lasting power supply. They can handle numerous recharges and discharges without causing damage to the battery cells. It is important to follow the recommendations of the manufacturer for charging which usually include charging the battery overnight 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 power to propel the wheelchair, which results in a longer battery life than rough terrains. If a wheelchair is driven on rocky or bumpy surfaces motors will have to be more efficient in order to maintain stability and speed and this consumes more energy and drains the battery more quickly.
The lifespan of batteries is impacted by its age and usage patterns. electric wheelchair for handicapped could be time to replace batteries if they are getting old and is losing its ability to keep charge. A newer battery will cut down on the time it takes to charge a wheelchair and will likely to be more powerful.
Wheelchair batteries are available in various sizes, with Group 22NF and Group 24 being the most popular options. The Group 22NF batteries weigh less and are smaller than the Group 24 batteries. This helps to reduce the weight and size of a wheelchair. However, they have a lower power or "juice" reserve than Group 24 batteries.
Avoid charging or subcharging the battery, as this can reduce its life. It is crucial to keep the battery in a cool, dry place, as extreme temperatures can alter the battery's performance.
Capacity for Weight
The weight capacity is an important aspect to consider when choosing a power wheelchair. If the chair will be used on long trips and long trips, then it should be able to support the user's weight. Weight issues can be caused by excessive weight, which can also cause battery life issues and accidents.
The weight of a power wheelchair differs from one model to another and is affected by the batteries it uses. It is also impacted by the amount and type of accessories it comes with, such as oxygen tank holders and various seating systems. The batteries are responsible for the majority of the weight. One battery can weigh up to 50 lbs by itself and a powerchair typically has two batteries!
The weight of a power wheelchair can be affected by the type of engine it is an engine with four poles or two. A four-pole motor is more efficient and can support greater capacity for weight. It will however require more energy and drain the batteries more quickly than a motor with just two poles.
Power wheelchairs may also have different drive bases, such as rear-wheel or mid-wheel. The position of the wheels can affect the maneuverability and handling of the wheelchair in different conditions. The base of the drive can include a variety of options, such as a swing-away control that helps with side-transfers and sip-and-puff controls that operate by blowing air on the sensor.
The environment where a power chair is used is another consideration. It's essential that the chair is able to move across a variety of terrains and fit into hallways and rooms. It is important to measure the doorways and ensure that the chair can pass through them. This includes hinged doors.
A physical therapist or mobility specialist can help you choose the right wheelchair for your needs. They can advise on factors like comfort, accessibility changes, seat size, and the weight of the wheelchair. They will also take into consideration the frequency and duration of use and whether the chair will be transported frequently.
Seating
Unlike manual wheelchairs, electric powered ones have motors that move them. This lets you move more freely and farther than a manual wheelchair however, there are some limitations.
In the beginning, you'll need know the capacity for weight of your new wheelchair. Whether it's your personal weight or the weight of any equipment or other items that you're carrying, it is important to never exceed the manufacturer's recommended weight limit to prevent overtaxing the power chair and damaging it.
Next, make sure your power chair has a comfortable seat and an appropriate footplate that you are able to fit into. If your feet aren't able to fit on the footplate of the chair, your center of gravity could be moved backwards, and the wheelchair may swivel.
Then, you should look for a power wheelchair that has tilt and recline functions to help reduce the risk of getting pressure sores. This feature is crucial for seniors whose skin can be thin and prone to bruises. Additionally, leg rests with power can help raise your legs and decrease swelling.
Like any other mechanical device, your wheelchair will require maintenance to ensure that it operates efficiently and safely. You'll need to inspect the battery as well as the tire pressure, brakes and other parts of your wheelchair frequently. You should also examine the seat for wear and make any necessary adjustments.
It is crucial to place your electric chair in a place which isn't exposed to extreme weather conditions. The exposure to high temperatures can degrade the frame, while exposure to low temperatures could cause damage to the battery and other electrical components.
If you don't buy your wheelchair from the your pocket, you won't be able to get insurance coverage, and you won't be able to return it if you discover that it doesn't meet your requirements. Manufacturer warranties typically last one to two years and cover the motors, electronics, joysticks and frames, but not the cushions on the back, seats or tires. Ask your supplier about their return policies prior to you purchase an electric wheelchair. Most importantly, go through the user's manual and follow the instructions for using and maintaining the device.
Operation
Power wheelchairs are driven by a motor inside the power base that sits under the seat of the user. The motor is powered by one or two rechargeable 12-volt batteries in series, for a total of 24 volts. LITH-TECH offers lithium batteries that are more energy efficient than lead acids and can be used for an extended period of time.
The controller as well as the electronics and power base can be modified to meet the needs of various users, with a variety of options available. For example, some chairs have adjustable seating to help ensure a comfortable fit and let the user find a position that best supports postural stability. Many chairs come with adjustable features, such as leg rest, seat height and recline positions, as well as the power tilt feature.
There are a variety of additional features available for electric powered wheelchairs, including oxygen tank holders elevating seats, and a variety of power accessories. Certain powerchairs are customized to allow the user to control them by using brainwaves or nerve signals.
Some 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. They can also be fitted with sensors that can warn of dangers or obstacles within the vicinity, and will automatically slow down or stop if necessary.
The position of the drive wheels, regardless of whether they're rear-wheels, mid-wheels or front-wheel drives has an enormous impact on the performance of a chair under different conditions. This is a huge topic, so we'll leave it for a future Clinical Corner.
Before taking your new electric wheelchair for a spin, check that it's fully charged, and that the tires have enough air pressure. It's also recommended to adjust the seat, armrests footrests (if applicable) and joystick, to prepare it for its first time use. Make sure you adhere to the instructions in the manual for operating your wheelchair, especially when driving up and down slopes. This will reduce the risk of injury and discomfort.
