Shopping For an Electric Powered Wheelchair
Electric powered wheelchairs can be a huge aid to those with limited mobility. You can find these chairs at specialty mobility equipment suppliers and a few major retailers. Medicare and private insurance may cover the cost of an electrical wheelchair if a doctor deems it medically necessary.
Most power wheelchairs have a joystick that users use to direct the motors. The controller, which functions as the brain of the wheelchair converts these movements into electrical signals.
Battery Life
Battery life is an important aspect to take into consideration when buying wheelchairs. A high-quality battery can last for up to two years if it is used regularly and maintained properly. The type of battery also affects the distance a wheelchair can travel on a single charge.
Deep cycle batteries are found in the majority of power wheelchairs. They provide a long lasting energy supply. These batteries can handle multiple discharges and recharges without harming the battery cells. It is important to follow the recommendations of the manufacturer for charging, which typically include charging the battery over the course of a night and avoiding letting it run completely empty.
The battery life is affected by the surface of the wheelchair. Smooth, level surfaces require less energy to propel the chair, resulting in longer battery life. If the wheelchair is driven on rocky or bumpy terrain, the motors need to work harder to maintain balance and speed, which consumes energy and drains batteries faster.
The life expectancy of batteries is affected by its age and use patterns. If a battery is old and is losing its capacity to hold the charge, it might be time for a replacement. A newer battery will decrease the time needed to charge a wheelchair and will likely to have more capacity.
Wheelchair batteries are available in several sizes including Group 22NF and Group 24 being the most well-known choices. Group 22NF batteries are smaller and lighter than Group 24 batteries, helping to reduce the weight and width of the power wheelchair. These batteries have a lower power reserve or "juice" than Group 24 batteries.
Avoid charging or subcharging the battery as it will reduce its lifespan. It is essential to keep the battery in a cool, dry place, as extreme temperatures can impact its functionality.
Capacity for Weight
The capacity to carry the weight of a chair is a crucial aspect to take into consideration. If the chair is intended to be used for long trips the chair must be capable of supporting the weight of the user's body. Excessive weight can lead to structural problems, reduced battery life, and an increased risk of accidents.
The weight of a power wheelchair varies from one model to the next and is influenced by the batteries it uses. The weight of a wheelchair is also affected by the amount of accessories and the kind of accessories, such as oxygen tanks holders and various seating systems. The batteries make up the majority of the weight. A single battery can weigh as much as 50 lbs, and most power chairs come with two batteries!
The weight of the power wheelchair can also be affected by whether it has an engine with four poles or two. A four-pole power wheelchair is more efficient and can carry the weight of a larger capacity. However, it will need more energy from the batteries and may drain faster than a two-pole.
Power wheelchairs also have different drive bases, like rear-wheel drive or mid-wheel drive. The position of the drive wheels can affect its maneuverability and handling in a variety of conditions. The base of the drive may include a range of options, like a swing-away controller that aids in side-transfers and sip-and-puff controls which work by blowing on the sensor.
The setting in which a power wheelchair is used is a different consideration. It's essential that the chair is able to move over varying terrain and be able to fit in hallways and rooms. It is crucial to measure the doors and ensure that the chair can navigate through them, even doors with hinges.
A physical therapist or mobility specialist can help select the best power wheelchair for the person. In addition to assessing the weight of the chair, its speed and driving range, they can also advise on other factors such as accessibility, comfort and seat size. They will also take into account the frequency and duration of use as well as if the chair will be transported regularly.
Seating
affordable electric wheelchairs have motors to move them, in contrast to manual wheelchairs. This lets you move more easily and farther than a manual wheelchair, but there are some limitations.
You'll first need to know 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.
Make sure that the power chair you choose has a comfortable footplate and a seat that you can comfortably fit in. If you don't have enough space for your feet to rest on the footplate, it can shift your center of gravity forward and cause the wheelchair to lunge.
Look for a power chair that has reclining and tilt functions to lower the chance of developing pressure sores. This feature is crucial for seniors whose skin can be thin and bruises easily. Leg rests that are powered are a great way to elevate your legs, which can reduce swelling.
Your wheelchair, like any mechanical device, will need regular maintenance to function properly and safely. You'll have to inspect the battery condition and tire pressure, brakes and other components of the device regularly. You should also inspect the seating for wear and tear and make any necessary adjustments.
It is crucial to keep your electric chair in a location which isn't exposed to extreme weather conditions. The frame could be damaged by high temperatures, and low temperatures can harm the battery and its electrical components.
Unless you're buying the wheelchair out of pocket, it won't be insured and you won't have the option to return it if it doesn't satisfy your requirements. Manufacturer warranties typically last between one and two years. They cover motors, joysticks, frames, and electronic components, but not back cushions, seats or tires. Ask your provider about their return policies prior to you purchase an electric wheelchair. Most importantly, read the user manual and follow all instructions on how to use and maintain the device.
Operation
The motor of a power wheelchair is located in the power base. It is located under the user's seat. The motor is powered by one or two rechargeable 12-volt batteries that are connected in series, giving 24 volts total. LITH-TECH provides lithium batteries, which are more efficient than lead acid batteries and can be used for longer durations of time.
Many options are available for customizing the controller, electronics and power base to meet the specific needs of each user. Some chairs allow for customizable seating, which will ensure a comfortable fit. It also allows the user to determine the best position that will help their posture. Many chairs come with adjustable features like leg rest, seat height and recline positions, in addition to the power tilt feature.
Electric powered wheelchairs can be equipped with a range of accessories. They include oxygen tank holders, elevating chairs and an array of accessories for power. Certain powerchairs are customized to allow users to control them using their brainwaves or nerve signals.
Some powerchairs also be adjusted in their speed according to the user's preference or to match the speed of other vehicles on the road, such as when climbing hills. They can also be fitted with sensors that warn of dangers and obstacles in the area and will then automatically slow down or swerve when necessary.
The positioning of the drive wheels - whether front-wheel, mid-wheel or rear-wheel drive - has a big impact on the way the chair performs under different conditions. This is a vast topic, so we'll leave it for a later Clinical Corner.
Before you take your new electric wheelchair out for an outing, make sure it's fully charged and that the tires have enough air pressure in them. To prepare for the first time, it's a good idea make some adjustments to your chair, armrests, and footrests. Be sure to follow the manual's instructions for operating your wheelchair, especially when driving on and down slopes. This reduces the chance of injury and discomfort.
