Shopping For an Electric Powered Wheelchair
Electric powered wheelchairs can be a huge aid to those who have a limited mobility. These chairs are sold at major retailers as well as specialist mobility equipment suppliers. Medicare and private insurance will pay for an electric wheelchair if considered medically necessary by a physician.
Most power wheelchairs come with a joystick that the user can use to control the motors. These movements are converted into electrical signals by a control unit that acts as the brain of the chair.
Battery Life
When looking for a power wheelchair one of the most important factors to consider is battery life. A high-quality battery will last for up to two years if used regularly and maintained properly. The type of battery also determines how far a wheelchair will be able to travel on one charge.
The majority of power wheelchairs have 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 to battery cells. It is important to adhere to the manufacturer's recommended charge practices. This includes overnight charging of the battery, and avoiding letting it run completely empty.
The battery's life is also affected by the surface of the wheelchair. Smooth, level surfaces require less power to propel the chair, which results in longer battery life. If the wheelchair is driven on rocky or bumpy terrain, the motors need to work harder in order to maintain balance and speed which takes energy and drains battery faster.
The age of a battery as well as its usage patterns can affect its longevity. It is possible to replace a battery if it is getting old and losing its ability to hold charge. A newer battery will cut down on the time required to charge a wheelchair and is likely to have more capacity.
Wheelchair batteries are available in a variety of sizes that include Group 22NF and Group 24 being the most popular options. Group 22NF batteries are smaller and lighter than Group 24 batteries, helping to decrease the overall weight and width of the power wheelchair. However, they have lower power or "juice" reserve than Group 24 batteries.
Beware of overcharging or subcharging your battery, as this can reduce its lifespan. Keeping the battery in a cool, dry area is also crucial, as exposure to extreme temperatures could adversely affect the battery's function.
Capacity of Weight
Weight capacity is an important factor to consider when choosing the best power wheelchair. If agree with this is intended to be used for long-distance trips, it will need to be able to support the user's body weight. Problems with weight can be caused by excessive weight, which can result in problems with battery life and accidents.
The weight of a power wheelchair differs between models and is affected by its batteries. It also affects the variety and types of accessories it has like oxygen tank holders and various seating systems. However, most of its weight is derived from the batteries. One battery can weigh as much as 50 lbs by itself and a powerchair typically has two batteries!
The power wheelchair's a two-pole motor or four-pole motor could affect its weight. A four-pole motor is more efficient and can provide a higher weight capacity. However, it requires more energy and drain batteries more quickly than a motor that has two poles.
Power wheelchairs may also have different drive bases, such as rear-wheel or mid-wheel. The location of the drive wheels can make a difference in the maneuverability and handling of the wheelchair in various conditions. The base of the drive can include a variety of options, including a swing-away control that helps with side-transfers, or sip-and-puff controls that operate by blowing air on a sensor.
The environment where a power chair is used is another consideration. It is essential that the chair is able to move across different terrains and be able to be able to fit into rooms and hallways. It is crucial to measure the doorways and ensure that the chair is able to move through them, including those with hinged doors.
A physical therapist and/or mobility specialist can help select the appropriate power wheelchair for the person. In addition to evaluating the weight of the chair, its speed and driving range, they can also advise on other aspects such as comfort, accessibility modifications and seat size. They also take into consideration the frequency and duration of use and whether the chair will be moved frequently.
Seating
Electric wheelchairs come with motors that move them, unlike manual wheelchairs. This lets you move more freely and further than a manual wheelchair however, there are some limitations.
You'll first need to know the weight capacity of your wheelchair. You should never exceed the recommended weight limit, regardless of whether it's your own or any equipment or other items that you're carrying.
Then, ensure that your chosen power chair is comfortable and has an appropriate footplate that you are able to fit into. If you don't have enough room for your feet to rest on the footplate, it could shift your center of gravity forward and cause the chair to slouch.
Then, you should look for a wheelchair that has tilt and recline functions to help reduce the risk of pressure sores. This feature is especially important for those who are older, as their skin is thin and can easily bruise. Power leg rests are also a great way to elevate your legs, which could reduce swelling.
Like all mechanical devices, your wheelchair will require maintenance to ensure that it performs safely and efficiently. You'll have to check the battery as well as the tire pressure, brakes and other parts of your wheelchair frequently. You should also check the seating for wear and make any necessary adjustments.
It is essential to keep your electric chair in a location that is not exposed to extreme weather conditions. The frame could be damaged by high temperatures, while low temperatures can damage batteries and electrical components.
If you don't purchase your wheelchair from a private source it isn't covered by insurance and you won't be able return it if it's not meeting your requirements. Manufacturer warranties typically last between one and two years and cover motors electronic, joysticks, and electronics frames but not the cushions on the back, seats or tires. Before purchasing an electric wheelchair, inquire with your dealer about their return policy. Most importantly, review the user's manual thoroughly and follow all instructions regarding the use and maintenance of the device.
Operation
The motor of the power wheelchair is situated in the power base. This is under the user's seat. The motor is powered by one or two rechargeable 12-volt batteries that are connected in series, resulting in a total of 24 volts. LITH-TECH offers lithium batteries that are more efficient in energy than lead acids and can be used for an extended period of time.
The controller electronics, power base and controller can be modified to meet the needs of different users, with many options available. Some chairs allow for individual seating that will ensure a comfortable fit. It also allows the user to find the position that best supports their postural stability. Many chairs come with adjustable features such as leg rest, seat height and recline positions, as well as the ability to tilt with power.
Electric powered wheelchairs can come with a range of accessories. They include oxygen tank holders, elevating chairs and an array of accessories for power. Some powerchairs can also be customized to allow the user to control them using their own brainwaves or nerve signals.
Some powerchairs have the ability to adjust the speed to the preferences of the user, or to match other vehicles on the road. For example, when driving uphill. They are also equipped with sensors that can warn of obstacles and other potential hazards in the vicinity and automatically slow down or swerve in the event of a need.
The position of the drive wheels - whether they are rear-wheel, mid-wheel or front-wheel drive - has a significant impact on how the chair performs under various conditions. This is a massive topic, so we'll leave it for a future Clinical Corner.
Before you take your brand new electric wheelchair for a spin, check that it's fully charged and the tires have enough air pressure in them. To prepare for the first time it's best to make some adjustments to your chair, armrests, and footrests. It's important to read the directions in your manual when operating your wheelchair. This is especially true when driving on and down hills. This reduces the chance of discomfort and injuries.
