Shopping For an Electric Powered Wheelchair
Electric powered wheelchairs can be an excellent help to people with limited mobility. These chairs are available at specialist mobility equipment suppliers and some major retailers. Medicare and private insurance could cover the cost of an electrical wheelchair if a physician deems it medically necessary.
Most power wheelchairs come with a joystick, which the user can use to control the motors. The controller, which functions as the brain of the wheelchair converts these movements into electrical signals.
Battery Life
When looking for a power wheelchair one of the most important factors to consider is the battery's life. A high-quality battery will last for two years with regular use and proper maintenance. The type of battery also affects how far the wheelchair can be able to travel on one charge.
Deep cycle batteries are utilized in a majority of power wheelchairs. They provide a long lasting energy source. They can handle numerous recharges and discharges without harming the battery cells. It is essential to follow the manufacturer's recommended charging practices, which typically include overnight charging of the battery and avoiding allowing it to run completely empty.
The surface on which the wheelchair operates also influences the battery's lifespan. Smooth, level surfaces require less energy to propel the chair, which results in longer battery life. If a wheelchair is driven on rocky or bumpy surfaces motors will have to perform harder to maintain speed and stability which means that they consume more energy and drains the battery faster.
The age of a battery and the way it is used can influence its lifespan. If a battery is old and losing its ability to hold an charge, it could be time for a replacement. A newer battery will decrease the time it takes to charge a wheelchair and will likely to have more capacity.
Wheelchair batteries are available in various sizes including Group 22NF and Group 24 being the most sought-after choices. Group 22NF batteries are smaller and lighter than Group 24 batteries, which help to decrease the overall weight and size of a power wheelchair. They have a smaller power reserve or "juice" than Group 24 batteries.
It is recommended to avoid charging or undercharging the battery since this could result in the battery's lifespan. It is important to keep the battery in a dry, cool place, as extreme temperatures can affect its functionality.
Capacity of Weight
Weight capacity is a key aspect to take into account when selecting the best power wheelchair. If the chair is going to be used for long journeys the chair must be able to support the user's weight. Excessive weight can lead to structural issues, a decrease in battery life and a greater chance of causing accidents.
The weight of a power chair is different from model to model and is affected by the type of batteries it is powered by. It also is affected by the variety and types of additional accessories it has such as oxygen tank holders and various seating systems. However, most of its weight comes from the batteries. One battery can weigh as much as 50 pounds on its own and a powerchair typically has two batteries!
Whether the power chair has either a four-pole or two-pole motor could influence its weight. A four-pole power wheelchair is more efficient and can carry more weight capacity. However, it will require more energy and drain batteries faster than a motor that has two poles.
Power wheelchairs may also come with different drive bases such as mid-wheel or rear-wheel. The location of the wheels can affect its maneuverability and handling under various conditions. The base of the drive can offer a range of options, like the swing-away control, which helps with side-transfers, or sip-and-puff controls that operate by blowing on a sensor.
Another aspect to consider is the environment where the power wheelchair will be used. It is essential that the chair be able to travel across different terrains and be able to be able to fit in hallways and rooms. It is crucial to measure the doorways and ensure that the chair is able to maneuver through them, including those with hinged doors.
A physical therapist or mobility specialist can assist you in choosing the right wheelchair for your needs. In addition to evaluating the wheelchair's weight, speed and driving range They can also provide advice on other factors such as comfort, accessibility modifications and seat size. They also take into consideration the frequency and duration of use as well as whether the chair will be transported regularly.
Seating
Electric wheelchairs are powered by motors to move them, in contrast to manual wheelchairs. This allows you to move more and greater mobility than a manual one, but it comes with some limitations and additional factors that you should consider.
First, you'll need to determine the weight capacity of your chair. It is important to never exceed the weight limit of your power chair's recommended limit, regardless of whether it's you or any other equipment or items that you're carrying.
Then, ensure that your chosen power chair has a comfortable seat and a footplate you can fit comfortably into. If your feet do not fit on the footplate of the chair, your center gravity can be reversed and the chair will slouch.
Then, you should look for a wheelchair that has tilt and recline functions to reduce the risk of pressure sores. This feature is especially important for those who are older, as their skin may be thin and easily bruise. Leg rests with power are an excellent way to raise your legs, which could reduce swelling.
As with any mechanical device the wheelchair will require regular maintenance to ensure that it performs well and safely. You'll have to check the battery as well as the brakes, tire pressure, and other parts of your wheelchair regularly. Also, attendant electric wheelchair should inspect the seating for wear and tear and make any necessary adjustments.
It is important to keep your electric chair in a space that is not exposed to extreme weather conditions. The frame may be damaged by high temperatures, while low temperatures can cause damage to electrical components and the battery.
Unless you're buying the wheelchair out of pocket the wheelchair will not be insured and you won't be able return it if it's not meeting 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. Check with your supplier for their return policies before you purchase an electric wheelchair. The most important thing to do is read the manual thoroughly and follow the guidelines for maintenance and use.
Operation
The motor of a power wheelchair is located in the power base. It is situated beneath the seat of the user. The motor is powered by rechargeable batteries that are 12 volts connected in series, for a total voltage of 24 volts. LITH-TECH offers lithium batteries, that are much more efficient than lead acid batteries and can be used for longer periods of time.
There are a variety of options to modify the controller, electronics, and power base to meet the specific needs of every user. For example, some chairs have adjustable seating to ensure a comfortable fit and allow the user to find the most suitable position to support postural stability. A lot of chairs have adjustable features, such as the height of the seat, leg rest and recline positions, as well as the power tilt feature.
Electric powered wheelchairs can be fitted with a wide range of additional features. These include oxygen tank holders, elevating chairs and an array of power accessories. Certain powerchairs are customized to allow the user to control them by using brainwaves or nerve signal.
Some powerchairs can also have the capability to adjust their speed to suit the user's preference or to match the speed of other vehicles on the road, for instance when going up hills. Some powerchairs have sensors that warn them of obstacles or other potential hazards nearby, and will automatically slow down and turn when necessary.
The positioning of the drive wheels - whether rear-wheel, mid-wheel or front-wheel drive - has a significant impact on how the chair performs under different situations. This is a huge subject, so we'll save it for a future Clinical Corner.
Check that your brand new electric chair is fully charged and the tires are inflating to the correct pressure before you take it for an excursion. To get ready for your first time it's best to make some adjustments to your chair, armrests, and footrests. Remember that it's important to adhere to the instructions in the manual for operating your wheelchair, especially when driving on and down slopes. This will reduce the risk of injury, damage and discomfort.
