Shopping For an Electric Powered Wheelchair Electric powered wheelchairs can be a huge help to people with mobility issues. These chairs are available at major retailers and specialty mobility equipment suppliers. Medicare and private insurance may cover the cost of an electric wheelchair if a doctor deems it medically necessary. The majority of power wheelchairs feature an electronic joystick that the user uses to direct the motors. The controller, which functions as the brain of the wheelchair, converts these movements into electrical signals. Battery Life When shopping for a power wheelchair one of the most important factors to consider is battery life. A quality battery can last up to two years if it is used regularly and maintained properly. The type of battery also affects the distance that wheelchairs can travel on one charge. Deep cycle batteries are utilized in most power wheelchairs. They provide a long lasting energy supply. They can handle numerous discharges and recharges without harming the cells in the battery. 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 surface on which the wheelchair operates can affect the battery's life. Smooth smooth, level surfaces require less power to propel the wheelchair, leading to a longer battery longevity than rough terrains. If a wheelchair is driven on bumpy or rocky surfaces the motors will need to be more efficient in order to maintain stability and speed which means that they consume more energy and drains the battery quicker. The lifespan of batteries is affected by the age of the battery and its usage. It is possible to replace the battery if it's getting old and losing its ability to hold charge. A newer battery could help reduce the amount of time that a wheelchair has to be charged, and is more likely to have a greater capacity than older batteries. Wheelchair batteries are available in several sizes, with Group 22NF and Group 24 being the most sought-after choices. The Group 22NF batteries weigh less and are smaller than Group 24 batteries. This reduces the overall weight and size of the wheelchair. However, they have lower power or “juice” reserve than Group 24 batteries. It is important to avoid charging or undercharging the battery, because this can cause it to shorten its life span. It is crucial to keep the battery in a cool, dry area, since extreme temperatures can affect its functionality. Capacity of Weight The capacity to carry the weight of a chair is a key factor to take into account. If the chair is intended to be used for long journeys the chair must be capable of supporting the weight of the person. A heavy weight can cause structural problems, decreased battery life, and an increased chance of causing accidents. The weight of a power wheelchair differs from model to and is affected by the type of batteries it is powered by. electric wheelchair for adults of a power chair is also affected by the number of accessories and the type of accessories, including oxygen tanks holders as well as different seating systems. However, most of its weight is derived from the batteries. One battery can weigh up to 50 lbs by itself, and a power chair typically has two batteries! Whether the power wheelchair has either a four-pole or two-pole motor will also affect its weight. A four-pole power wheelchair is more efficient, and it can support the weight of a larger capacity. It will however require more energy and drain the batteries faster than a motor with two poles. Power wheelchairs can also come with various drive bases, such as rear-wheel drive or mid-wheel drive. The location of the drive wheels may make a difference in the maneuverability and handling of the wheelchair under various conditions. The drive base may contain a variety of options, including a swing-away control that helps with side-transfers or sip-and puff controls that operate by blowing on the sensor. Another consideration is the environment where the power wheelchair will be employed. It is important that the chair is able to be used on different terrains and can be fitted into rooms and hallways. It is essential to measure the doorways and ensure that the chair will fit through them. This includes hinged doors. A physical therapist or mobility specialist can help select the right power wheelchair for the person. They can offer advice on aspects such as comfort, accessibility adjustments, seat size, and weight of the wheelchair. They also take into consideration the frequency and duration, and whether the chair is likely to be moved frequently. Seating Electric wheelchairs are powered by motors to move them, unlike manual wheelchairs. This gives you more mobility and a greater range than a manual chair, however, it has some limitations and additional factors that you need to take into consideration. In the beginning, you'll need be aware of the capacity of your new chair. Whether it's your personal weight or the weight of any equipment or supplies you're carrying, you should not exceed the manufacturer's recommended weight limit in order to avoid overloading the power chair and causing damage. Make sure that the chair you select has a comfortable footplate and a seat that you can fit in. If there isn't enough space for your feet to rest on the footplate, it can shift your center of gravity backward and cause the wheelchair to slouch. Finally, look for a power wheelchair that has tilt and recline capabilities to decrease the chance of developing pressure sores. This feature is essential for seniors whose skin can be thin and prone to bruises. Moreover, power leg rests can help raise your legs and decrease swelling. Like any other mechanical device, requires regular maintenance to perform well and safely. You'll need to check the battery condition, tire pressure, brakes and other parts of the device regularly. Also, you should check the seating for wear and make any adjustments that are needed. It is crucial to store your electric chair in a place that will not expose it to extreme weather conditions. Exposed to extreme temperatures could affect the frame's condition, while exposure to low temperatures can harm the battery as well as other electrical components. Unless you're buying your wheelchair out-of-pocket it isn't covered by insurance and you won't be able return it if it doesn't meet your requirements. Manufacturers' warranties usually last between one and two years. They include joysticks, motors frames, and electronic components but not back cushions, 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 all the directions regarding the use and maintenance of the device. Operation The motor of the power wheelchair is situated in the power base. It is situated beneath the seat of the user. The motor is powered by two or one rechargeable 12-volt batteries in series, giving 24 volts total. LITH-TECH offers lithium batteries, which are much more efficient than lead acid batteries and can be used for longer periods of time. Many options are available to customize the controller, electronics, and power base to meet the requirements of every user. Certain chairs offer customizable seating, which can help to ensure the most comfortable fit. It can also help the user choose the ideal position that will help their posture. Many models include adjustable features such as the height of the seat, leg rest and recline positions, as well as power tilt functionality. There are many additional extras offered for electric powered wheelchairs, such as oxygen tank holders, elevating seats, and a variety of power accessories. Certain powerchairs are customized so that the user can control them using their brainwaves or nerve signal. Certain powerchairs have the capability to adjust their speed to accommodate the user's preference or to match the speed of other vehicles on the road, for example when driving up hills. They can also be fitted with sensors that alert you to dangers and obstacles in the vicinity, and will automatically slow down or swerve when necessary. The position of the drive wheels – whether they're front-wheel, mid-wheel or rear-wheel drive – can have a huge impact on how a chair performs in different conditions. This is a vast topic, so we'll leave it for a future Clinical Corner. Check that your new electric chair is fully charged and the tires are at the right pressure prior to taking it for an excursion. It's also recommended to make a few adjustments to the seat, armrests footrests (if applicable) and joystick, to prepare it for first time use. Be sure to follow the manual's instructions for operating your wheelchair, especially when driving up and down slopes. This reduces the chance of injury, damage and discomfort.
