Shopping For an Electric Powered Wheelchair
An electric powered wheelchair can be very beneficial for individuals with limited mobility. These chairs are available at specialized mobility equipment providers and a few major retailers. Medicare and private insurance may cover the cost of an electric wheelchair when it's determined to be medically necessary by a physician.
The majority of power wheelchairs come with an instrument that the user uses to direct the motors. These movements are converted to electrical signals by a controller which acts like the brain of the chair.
Battery Life
Battery life is a crucial factor to consider when buying wheelchair. A quality battery can last up to two years if it is regularly used and maintained. The type of battery also affects how far the wheelchair can travel on a single charge.
The majority of power wheelchairs have deep cycle batteries that are designed to provide a long-lasting power supply. These batteries can handle multiple recharges and discharges without damaging the cells of the battery. It is important to adhere to the guidelines of the manufacturer for charging. This includes overnight charging of the battery and avoiding leaving it running at a complete loss.
The battery life is also affected by the surface of the wheelchair. Smooth, level surfaces require less power to propel the chair, leading to longer battery life. If a wheelchair is used on bumpy or rocky surfaces motors will have to perform harder to maintain speed and stability, which consumes more energy and drains the battery faster.
The age of a battery as well as the way it is used can impact its longevity. It is possible to replace the battery if it's becoming old and is losing its ability to hold charge. A newer battery can help reduce the time a wheelchair must be charged, and is more likely to have more capacity than older batteries.
Wheelchair batteries are available in several sizes that include Group 22NF and Group 24 being the most well-known choices. The Group 22NF batteries weigh less and are smaller than Group 24 batteries. This reduces the overall weight and size of a wheelchair. However, they have less power or "juice" reserve than Group 24 batteries.
It is important to avoid charging too much or undercharging your battery, as this can cause it to shorten its lifespan. Keeping the battery in a dry, cool place is also important since exposure to extreme temperatures could affect the battery's performance.
Capacity for Weight
The weight capacity is an important aspect to consider when choosing the best power wheelchair. If the chair is to be used for long trips it must be able to support the weight of the person. Weight issues are often caused by excess weight, which could cause accidents and battery life issues.
The weight of a power chair varies from one model to another and is affected by the batteries it uses. The weight of a power wheelchair is also affected by the number of accessories and the kind of accessories, like oxygen tanks holders and various seating systems. However, the majority of its weight comes from the batteries. One battery can weigh up to 50 lbs alone and a powerchair usually has two of them!
Whether the power chair has either a four-pole or two-pole motor could influence the weight of the wheelchair. A four-pole power wheelchair is more efficient, and has the weight of a larger capacity. It will however require more energy and drain batteries more quickly than a motor with just two poles.
Power wheelchairs could also come with different drive bases such as mid-wheel or rear-wheel. The position of the wheels can affect its handling and maneuverability in various conditions. The drive base may offer a range of options, such as an adjustable swing-away control that assists with side-transfers, or sip-and-puff controls that work by blowing air on the sensor.
The setting where a power chair is used is another factor to take into consideration. It is essential that the chair be used on different surfaces and be able to fit into hallways and rooms. It's important to measure 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 assist in selecting the appropriate power wheelchair for the individual. 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 consider the frequency and duration of use as well as whether the chair is transported frequently.
Seating
Electric wheelchairs are powered by motors to move them, unlike manual wheelchairs. This allows you to move more easily and farther than a manual wheelchair however, there are some limitations.
First, you'll need to be aware of the capacity for weight of your new wheelchair. You should never exceed the recommended weight limit, whether it's you or any equipment or other items that you're carrying.
Then, ensure that your power chair has a comfortable seat and a footplate you can fit comfortably into. If your feet don't fit into the footplate of the chair, your center of gravity could be moved backwards, and the wheelchair will lunge.
Find a power chair that has reclining and tilt functions to lower the chance of developing pressure sores. This feature is essential for seniors whose skin can be thin and prone to bruises. Additionally, leg rests with power can help elevate your legs and decrease swelling.
Like any other mechanical device, requires regular maintenance to perform well and safely. You'll have to check the battery and tire pressure, brakes and other parts of your device regularly. It is also recommended to check the seating for wear and tear, and make any adjustments that are needed.
It is important to store your electric chair in a space that will not expose it to extreme weather conditions. The frame could be damaged by high temperatures, while low temperatures can damage the battery and its electrical components.
If you don't purchase your wheelchair from a private source it won't be insured and you won't have the option to return it if it's not meeting your needs. Warranty warranties from manufacturers usually last between one and two years and cover motors, electronics, joysticks and frames, but not the back cushions, seats or tires. Ask ultra lightweight electric wheelchair about their return policy before you purchase an electric wheelchair. Most importantly, go through the user's manual and follow all instructions regarding the use and maintenance of the device.
Operation
The motor of a power wheelchair is found in the power base. This is beneath the seat of the user. The motor is powered by two 12-volt rechargeable batteries connected in series for an overall voltage of 24 volts. LITH-TECH has lithium batteries that are much more energy efficient than lead acid batteries and can be used for longer durations of time.
The controller electronics, power base and controller can be modified to meet the needs of various users, with many options available. For instance, some chairs have adjustable seating to ensure a comfortable fit and let the user choose 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, in addition to the ability to tilt with power.
Electric powered wheelchairs can come with a variety of extras. These include oxygen tank holders, elevating chairs and many other power accessories. Certain powerchairs are customized so that the user can control them with their brainwaves or nerve signal.
Some powerchairs have the ability to alter the speed according 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 warn of obstacles and other potential hazards within the vicinity, and will automatically slow down or swerve when necessary.
The location of the drive wheels - whether front-wheel, rear-wheel, or mid-wheel drive - has a big impact on the way a chair performs in different situations. But, it's a huge issue that we'll keep for the next Clinical Corner article.
Before you take your new electric wheelchair for an outing, make sure it's fully charged and the tires have enough air pressure in them. To get ready for your first time it's recommended to make some adjustments to your chair, armrests and footrests. It's essential to follow the instructions in your manual prior to operating your wheelchair. This is especially important when driving up and down hills. This reduces the chance of injury, damage or discomfort.
