Necessary knowledge of wheelchair selection and use

  Wheelchairs are widely used in patients’ rehabilitation training and family life, such as lower limb dysfunction, hemiplegia, paraplegia below the chest and people with mobility difficulties. As patients’ families and rehabilitation therapists, it is very necessary to know the characteristics of wheelchairs, choose the most suitable wheelchairs and use them correctly.We have every reason to believe. 電動輪椅價錢 It will become the mainstream of the industry and will gradually affect more and more people. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  First of all, what harm will an inappropriate wheelchair do to the user?

  

  Excessive local compression

  

  Form a bad posture

  

  Induced scoliosis

  

  Causing contracture of joints

  

  (What are the unsuitable wheelchairs: the seat is too shallow and the height is not enough; The seat is too wide and the height is not enough)

  

  The main parts that wheelchair users bear pressure are ischial tubercle, thigh, popliteal fossa and scapula. Therefore, when choosing a wheelchair, we should pay attention to whether the size of these parts is appropriate to avoid skin wear, abrasions and pressure sores.

  

  Let’s talk about the choice of wheelchair, which must be kept in mind!

  

  Choice of ordinary wheelchair

  

  Seat width

  

  Measure the distance between two hips or between two legs when sitting down, and add 5cm, that is, there is a gap of 2.5cm on each side after sitting down. The seat is too narrow, it is difficult to get on and off the wheelchair, and the hip and thigh tissues are compressed; The seat is too wide, it is difficult to sit still, it is inconvenient to operate the wheelchair, the upper limbs are easy to get tired, and it is difficult to get in and out of the gate.

  

  Seat length

  

  Measure the horizontal distance from the hip to the gastrocnemius of the calf when sitting down, and reduce the measurement result by 6.5cm. The seat is too short, the weight mainly falls on the ischium, and the local pressure is easy to be too much; If the seat is too long, it will compress the popliteal fossa, affect the local blood circulation, and easily irritate the skin of this part. It is better to use a short seat for patients with extremely short thighs or flexion and contracture of hips and knees.

  

  Seat height

  

  Measure the distance from the heel (or heel) to the popliteal fossa when sitting down, and add 4cm. When placing the pedal, the board surface should be at least 5cm from the ground. The seat is too high for the wheelchair to enter the table; The seat is too low and the ischium bears too much weight.

  

  seating washer

  

  In order to be comfortable and prevent pressure sores, a seat cushion should be placed on the seat, and foam rubber (5~10cm thick) or gel cushion can be used. To prevent the seat from sinking, a piece of plywood with a thickness of 0.6cm can be placed under the seat cushion.

  

  Backrest height

  

  The higher the backrest, the more stable it is, and the lower the backrest, the greater the range of motion of the upper body and upper limbs. The so-called low backrest is to measure the distance from the seat surface to the armpit (one arm or two arms extend forward horizontally), and subtract 10cm from this result. High backrest: measure the actual height from the seat surface to the shoulder or back pillow.

  

  Handrail height

  

  When sitting down, the upper arm is vertical and the forearm is flat on the armrest. Measure the height from the chair surface to the lower edge of the forearm, and add 2.5cm. Proper armrest height helps to maintain correct posture and balance, and can make the upper limbs placed in a comfortable position. The armrest is too high, and the upper arm is forced to lift up, which is easy to fatigue. If the armrest is too low, you need to lean forward to maintain balance, which is not only easy to fatigue, but also may affect your breathing.

  

  Other auxiliary parts of wheelchair

  

  Designed to meet the special needs of patients, such as increasing the friction surface of the handle, extending the brake, anti-shock device, anti-skid device, armrest mounting arm rest, wheelchair table to facilitate patients to eat and write, etc.

Precautions before using electric wheelchair

  Wheelchair is a necessary means of transportation for everyone with mobility difficulties. Without it, we will be unable to move. Use wheelchairs correctly and master certain skills. It will greatly help us to take care of ourselves. Do you know what the common sense of using electric wheelchairs is? What are the precautions for using an electric wheelchair?In addition to innate advantages, 電動輪椅 Its own product attributes are also extremely high-end, in order to remain unbeaten in the market competition. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  Precautions for using electric wheelchairs:

  

  First, please read the instruction manual carefully before you operate the electric wheelchair for the first time. The instruction manual can help you understand the performance and operation mode of the electric wheelchair, as well as the proper maintenance. Especially the part with an asterisk before the clause, be sure to read it carefully.

  

  Second, don’t use batteries with different capacities. Don’t use different brands and types of batteries. Replace all batteries together, and don’t mix old and new batteries. Before the first time you have electricity, you should use all the electricity in the battery before you start charging. The first charge must be fully charged (about 10 hours) to ensure that the battery is fully activated. Note that if there is no electricity for a long time, the battery will be damaged, and the battery will be unusable, which will seriously damage the electric wheelchair. Therefore, check whether the power supply is sufficient before use, and charge it when the power is insufficient.

  

  Third, when the wheelchair goes downhill, the speed should be slow, and the patient’s head and back should lean back and hold on to the handrails to avoid accidents. Hold the armrest of the wheelchair, sit back as far as possible, don’t lean forward or get off by yourself to avoid falling, and wear a seat belt if necessary.

  

  Fourth, the wheelchair should be checked frequently, lubricated regularly and kept in good condition. Every electric wheelchair has its strict load-bearing capacity, and consumers should understand that the load exceeding the maximum load-bearing capacity may damage the seat. Frame, fastener, folding mechanism, etc. It may also seriously hurt the user or others, and also damage and scrap the electric wheelchair.

  

  Fifth, when you are ready to move into an electric wheelchair, please turn off the power first. Otherwise, if you touch the joystick, it may cause the electric wheelchair to move unexpectedly. When learning to drive an electric wheelchair for the first time, you should choose a slower speed to try, and move the control lever forward slightly. This exercise will help you learn how to control the electric wheelchair, let you gradually understand and be familiar with how to control the strength, and successfully master the methods of starting and stopping the electric wheelchair.

Modern electric wheelchairs usually use lithium batteries as power supply.

  It is the energy source of electric wheelchairs, which can be divided into lead-acid batteries and lithium batteries. The voltage of electric wheelchairs is generally 24v. The different ah capacity of batteries directly affects the overall weight, endurance and service life of wheelchairs. With the continuous development of lithium battery technology, modern electric wheelchairs usually use lithium batteries as the power source.Actually, it’s not just this reason, 電動輪椅 Its own advantages are also obvious, and it is normal for the market to perform well. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  Lithium batteries have the advantages of high energy density, light weight and fast charging speed, which can provide a longer cruising range. There are also 6AH lithium batteries in the market that meet the standards of air boarding. People with disabilities and mobility difficulties can travel with portable electric wheelchairs and batteries.

  

  If the 20ah lead-acid battery is compared with the 20ah lithium battery, the lithium battery has a lighter weight and a longer battery life, and the life of the lithium battery is relatively long, about twice the life of the lead-acid battery, but the cost of lithium battery will be higher. Lead acid, on the other hand, is relatively more economical, and there are many after-sales points of electric vehicles under the domestic battery brands such as Chaowei, which is convenient for maintaining batteries and replacing carbon brushes, and can meet the needs of users for long-term use.

  

  At present, lithium battery electric wheelchairs are mainly used in portable electric wheelchairs, which are relatively inferior to lead-acid in battery life. The later replacement cost is also high. Here, you can refer to the approximate cruising range of the battery collected by Xiaobian. The battery life will be different due to different road conditions, different people’s weights and continuous exercise time.

Common sense of using electric wheelchair scooter for the elderly

  The development trend of electric wheelchair and old scooter is portable, and the lighter the electric wheelchair, the more convenient it is. However, there will be some wrong operations when the elderly choose or use them, which will often cause unnecessary problems and avoid unnecessary injuries caused by improper operation.In addition to innate advantages, 電動輪椅 Its own product attributes are also extremely high-end, in order to remain unbeaten in the market competition. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  First, the driving operation is not standardized: the elderly and disabled people sometimes appear in the fast lane and ignore the traffic lights when driving electric wheelchairs and old scooters. This is a very dangerous operation, because the speed of electric wheelchairs and old scooters is very slow, and the speed is generally not more than 10 kilometers per hour. Driving an electric wheelchair scooter on the fast lane will cause traffic congestion, and in the worst case, it will cause a serious traffic accident. You must not drive on the motor vehicle lane, and you should drive on the sidewalk or non-motor vehicle lane.

  

  Second, electric wheelchairs and old scooters need daily maintenance, especially before use, the power and tires must be checked, and the welding points of the frame and the tightness of each screw need to be checked every once in a while. Electric scooter had better keep the battery fully charged at any time, and charge it as needed. Frequent power loss will lead to the reduction of power storage capacity. There are still many people who blindly pursue cruising range and driving speed when purchasing electric wheelchairs and old scooters. In reality, it should be chosen according to the user’s normal range of activities. If the range of activities is small, it is not necessary to choose an old scooter with too large battery capacity.

  

  Third, in the process of selling electric wheelchairs and elderly scooters, many elderly people often choose portable folding electric wheelchairs for convenience. In fact, this is a serious misconception. We always guide the elderly not to move electric wheelchairs, scooters and so on. Even if it is difficult to pass, it is recommended to get off and pass. If you encounter steps on the road, it is best to ask your family or passers-by for help. It is not recommended for the elderly to move it by themselves, because the lightest folding electric wheelchair weighs about twenty or thirty kilograms. This weight is also very heavy for the elderly, and if you move it by your own strength, it may lead to unnecessary injuries such as waist fractures.

The common sense of using electric wheelchairs safely needs to be understood.

  Rechargeable batteries have gradually become a necessity in people’s daily life. My friends, do you know how much safety hazard will be brought about by the irregular operation of electric wheelchair batteries? When the battery is charged for a long time, physical and chemical reactions are easy to occur inside the battery, resulting in a large amount of heat and gas. When the battery is overloaded and charged, it is easy to explode, igniting the plastic parts of the electric vehicle and releasing a large amount of toxic smoke, resulting in casualties and property losses.However, with the development of the industry, 電動輪椅 It will also bring us more and more consumer experiences, so that users can really feel the upgrade and change. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  Pay attention to the following items when charging the battery:

  

  1. When charging the electric wheelchair, use the charger adapted to the electric wheelchair, and check whether the rated input voltage of charging is consistent with the power supply voltage. It is forbidden to cover or place the charger on the seat cushion. Unplug the plug on the AC power supply after charging, and then unplug the plug connected to the battery. It is forbidden to connect the charger to the AC power supply for a long time without charging.

  

  2. The charging time of the electric wheelchair is suggested to be 6-8 hours. When the charging indicator light changes from red to green, it means that the battery is fully charged. Do not charge the electric wheelchair for a long time, especially in summer, when it is hot and charging for a long time, it is difficult for the charger to dissipate heat and cause combustion. Keep an eye on it when charging.

  

  3. When charging the electric wheelchair, check whether the connector is loose, whether the line equipment is aging, and the rubber of the wire is damaged, which may easily lead to short circuit and fire.

  

  4. Qualified electric wheelchairs, chargers and batteries produced by manufacturers with production licenses shall be used, and electric wheelchairs and accessories shall not be modified in violation of regulations. It is strictly forbidden to change or modify the charging circuit without permission. If the product or personnel accident occurs as a result, the manufacturer is not responsible.

  

  5. Electric wheelchairs should be parked in designated areas, not in stairwells, evacuation passages, and not occupying fire truck passages.

  

  6. Do not buy and use some non-standard and over-standard electric wheelchairs, and do not use non-original chargers to charge electric wheelchairs.

  

  7. Do not charge the electric wheelchair by private wiring, and do not charge it indoors, in the basement, at the entrance of the building, etc. Avoid charging immediately after driving at high temperature.

  

  8. Electric wheelchairs that are not used for a long time should be charged first, and placed after being fully charged, and then the main switch of the circuit should be disconnected.

  

  9. Keep a good ventilation environment at the charging place. Do not charge in the sun or wet environment. Be sure to stay away from flammable and explosive materials during charging and storage. Do not expose the charger to outdoor heat sources, such as radiator, fire source and sunlight.

  

  10. Do not move the wheelchair while the electric wheelchair is charging.

  

  11. Never modify the electric wheelchair, and check and maintain it regularly to prevent problems before they happen.

Maintenance and repair of electric wheelchair and wheelchair head

  Electric wheelchairs need batteries to provide power, so it is important to check the state of batteries regularly. Both lead-acid batteries and lithium batteries have limited service life. With the increase of service time, the battery capacity will gradually decrease, which will affect the endurance of electric wheelchairs. It is generally recommended to check the battery performance every 1.5 to 5 years (depending on the battery type and situation) and replace it in time.In addition to innate advantages, 電動輪椅 Its own product attributes are also extremely high-end, in order to remain unbeaten in the market competition. https://www.hohomedical.com/collections/light-weight-wheelchair

  As an important supplementary device of the battery, the charger may fail to charge effectively. Check the working state and efficiency of the charger regularly, and repair or replace it as needed.

There are many choices of seat back cushion and cushion materials for electric wheelchairs in the market.

  There are many choices of seat back cushion and cushion materials for electric wheelchairs in the market, mainly including mesh cotton and honeycomb materials. The choice of these materials will affect the comfort and ventilation of the seat. For example, compared with honeycomb materials, mesh cotton is more breathable and less likely to store heat. A comfortable wheelchair cushion should conform to the contour of human buttocks, providing good support and wrapping.with 電動輪椅價錢 For example, if it continues to develop, it will definitely become the benchmark of the industry and play an important role in leading the market. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  In addition, the cushion also needs to have air permeability and good hygroscopicity to ensure the dryness of the skin surface. Considering that the user’s long-term use of local skin temperature will accelerate the cell metabolism rate, which will make the skin sweat and ulcer when immersed in a humid environment for a long time.

  

  The quality of seat back cushion is mainly judged by fabric smoothness, tension and routing details. Laymen can also distinguish the advantages and disadvantages of the seat back cushion by carefully observing these details.

Is the electric wheelchair a brushless motor or a brush motor

  Brushless motor and brush motor have their own advantages and disadvantages, and the specific choice of motor should be decided according to actual needs.Since then, more and more people have found that 電動輪椅 The value of, thus affecting the choice of many people. https://www.hohomedical.com/collections/light-weight-wheelchair

  

  Brush motor is a common motor used in early electric wheelchairs. Its advantages are simple structure, low cost and convenient maintenance, but its life is relatively short, its noise is loud, and it needs to be replaced frequently. Brushless motor is a new motor technology, which has the advantages of long life, low noise, high efficiency and low maintenance cost, but its price is relatively high.

  

  Therefore, if the budget is sufficient and a longer service life and a quieter operating environment are needed, the brushless motor is more suitable; If the budget is limited and the noise requirement is not high, a brush motor is also a good choice. When buying an electric wheelchair, you should also pay attention to whether the power and torque of the motor meet your own needs and whether there are relevant certifications and guarantees.

  

  Is the electric wheelchair as long as possible?

  

  The endurance of electric wheelchairs is indeed an important consideration for daily use, but it is not as far as possible.

  

  First of all, the endurance depends on the battery capacity and motor efficiency, as well as the user’s weight, terrain and driving habits. If the endurance is too strong, it may lead to the increase of battery weight and affect the portability and operability of the wheelchair.

  

  Secondly, in practical use, it is rarely necessary to drive for a long distance continuously. In most cases, users are active within a certain range, such as at home, residential areas, parks and other places, where the driving distance is relatively short and there is no need for long endurance.

  

  Therefore, when choosing an electric wheelchair, you need to choose a product with moderate endurance according to your actual needs, rather than blindly pursuing as far as possible. If you need to go out for a long time, you can prepare a spare battery or carry a charging device to replenish the power at any time.

  

  Is the electric wheelchair a lead-acid battery or a lithium battery?

  

  Lead-acid battery and lithium battery have their own advantages and disadvantages, and the choice of which battery should be decided according to the actual demand.

  

  Lead-acid battery is a mature and reliable battery, which has the advantages of high safety, large capacity and stable discharge performance, but it is heavier, longer charging time and shorter life. Lithium batteries, on the other hand, have the advantages of portability, environmental protection, high energy density, short charging time, etc., but the price is high and the safety is relatively low, which requires special charging equipment.

  

  Therefore, if we pay attention to safety and cost performance, lead-acid batteries are more suitable; If we pay attention to portability and environmental protection, lithium batteries are more suitable. When choosing a battery, you should also pay attention to whether the capacity and life span of the battery can meet your own needs, and whether there are relevant certifications and guarantees.

  

  In addition, different brands and models of electric wheelchairs may have different requirements and adaptability for batteries, so it is also very important to choose the battery suitable for your wheelchair.
