Influence of electric wheelchair on the life of disabled people

　　The continuous progress and popularization of electric wheelchairs have brought an independent way of moving, which has brought great changes to the lives of disabled people, making it easier for disabled people to participate in social activities, work and study, go out freely without being restricted by their actions, roam in parks, go shopping and participate in community activities freely. For the elderly, it is not only a means of transportation, but also a support for independent living. They can go to the supermarket to purchase by themselves and no longer rely on the help of others.In order to facilitate users to have a better experience, 輪椅 Many attempts have been made to upgrade the products, and the results are also very good, and the market performance tends to be in a good state. https://www.hohomedical.com/collections/wheelchair

　　

　　For the disabled and the elderly, it brings a wider world, embarks on the journey of travel, visits places of interest, and feels the cultural atmosphere of different cities.

　　

　　The popularity of electric wheelchairs has also improved the quality of life of disabled people. Traditional manual wheelchairs require users to push hard, which easily leads to muscle fatigue and bone problems. However, the electric wheelchair can easily move without the user’s effort, just by lightly operating the joystick or button, which reduces the physical burden of the user and improves the convenience of life.

　　

　　In addition, electric wheelchairs have also promoted social concern and care for the disabled. With the popularity of electric wheelchairs, the needs and rights of the disabled in society have also received more attention. Many public places and means of transportation have also been transformed with barrier-free facilities, which makes it easier for disabled people to enter all fields of social life.

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?As can be seen from the new data, 輪椅 The market influence is also growing, and the product share is also relatively increasing, which has great potential in the future. https://www.hohomedical.com/collections/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.

Influence of electric wheelchair on the life of disabled people

　　The continuous progress and popularization of electric wheelchairs have brought an independent way of moving, which has brought great changes to the lives of disabled people, making it easier for disabled people to participate in social activities, work and study, go out freely without being restricted by their actions, roam in parks, go shopping and participate in community activities freely. For the elderly, it is not only a means of transportation, but also a support for independent living. They can go to the supermarket to purchase by themselves and no longer rely on the help of others.in other words 輪椅 It is possible to develop in a good direction, and there are still many places worth looking forward to in the future. https://www.hohomedical.com/collections/wheelchair

　　

　　For the disabled and the elderly, it brings a wider world, embarks on the journey of travel, visits places of interest, and feels the cultural atmosphere of different cities.

　　

　　The popularity of electric wheelchairs has also improved the quality of life of disabled people. Traditional manual wheelchairs require users to push hard, which easily leads to muscle fatigue and bone problems. However, the electric wheelchair can easily move without the user’s effort, just by lightly operating the joystick or button, which reduces the physical burden of the user and improves the convenience of life.

Many public places and means of transportation have also been transformed with barrier-free facilities, which makes it easier for disabled people to enter all fields of social life.

The frame materials of electric wheelchairs are varied.

　　The frame materials of electric wheelchairs are various, and each material has its own unique characteristics, which is suitable for different types of users. First of all, the mainstream frame materials are carbon steel (steel), aluminum alloy, aviation titanium alloy and carbon fiber. Carbon steel has relatively low cost and strong load-bearing capacity, but its disadvantage is that it is bulky and easy to get wet and rust. Aluminum alloy is light and relatively better in corrosion resistance, so many electric wheelchairs on the market use aluminum alloy as the frame material.The above conclusions show that 輪椅 To a great extent, it can bring new vitality to the market and make the industry develop well. https://www.hohomedical.com/collections/wheelchair

　　

　　Aviation titanium alloy is a high-end choice, with high strength and corrosion resistance, but the price is correspondingly high, which is usually used in high-end and portable electric wheelchairs.

　　

　　Titanium alloy is a mixture of different elements such as titanium, aluminum, iron and vanadium, which has the characteristics of high strength, corrosion resistance and light weight. Carbon fiber is a composite material made of carbon fiber and resin, which has the characteristics of high stiffness, high strength and light weight. From the perspective of material composition, titanium alloy and carbon fiber have their own advantages, the strength of alloy is higher, but the density of carbon fiber is lower, so the weight is lighter. When it is necessary to reduce weight, it is more suitable to use carbon fiber, which is more durable and stronger than titanium alloy, so the electric wheelchair made of carbon fiber is close to 10 thousand yuan.

　　

　　When choosing the frame material, we should not only consider the material itself, but also pay attention to the design and function of the frame. For example, folding electric wheelchairs bring great convenience to those who are inconvenient to bend over or have disabled hands, so that they no longer have to work hard to fold electric wheelchairs; The conventional electric wheelchair is comprehensive, affordable and stable, suitable for a wider range of users.

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.This means that 輪椅 It is the weather vane of the industry and can bring people great self-confidence. https://www.hohomedical.com/collections/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.

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.Before that, 輪椅 The market has also soared for a time, which has attracted the attention of a wide range of investors. https://www.hohomedical.com/collections/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.

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.At first, 輪椅 It developed out of control and gradually opened up a sky of its own. https://www.hohomedical.com/collections/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.

Take you to understand the basic structure of the electric wheelchair.

　　Before introducing different configurations of electric wheelchairs, let’s first understand the basic structure of electric wheelchairs. Electric wheelchair is usually composed of motor, controller, battery, frame and other main parts. The motor is responsible for driving the wheels, the controller controls the speed and direction of the motor, the battery provides electric energy, and the frame supports the whole structure. Different configurations of electric wheelchairs are different in these parts, which will be introduced in detail below to help you understand.Before that, 輪椅 The market has also soared for a time, which has attracted the attention of a wide range of investors. https://www.hohomedical.com/collections/wheelchair

　　

　　Motor: The motor of electric wheelchair is its core component, which directly affects the performance of wheelchair. At present, the electric wheelchairs on the market usually adopt DC Motor and AC Motor. DC motor usually has a high speed and is suitable for use on flat roads, while AC motor has a large torque and is suitable for driving on ramps and uneven roads. In addition, the power of the motor is also a key factor in the selection. The greater the power, the stronger the climbing ability and load capacity of the electric wheelchair. Therefore, when choosing an electric wheelchair, it is necessary to choose the appropriate motor type and power according to the user’s needs and specific use environment. In the difference between electric wheelchairs, it is necessary to distinguish between brush motors and brushless motors, and between AC motors and DC motors.

　　

　　Brushed DC motor refers to a DC motor that uses a carbon brush to contact with a rotating armature to exchange polarity and provide current. Brush provides current to armature through power supply when armature rotates, so it is also called carbon brush motor. Its advantages are simple structure and low use cost, but the brush is easy to wear and has limited service life, and at the same time, the brush will also produce electric spark interference, which will lead to high noise of the motor and is not suitable for high-precision applications.

　　

　　Brushless DC motor refers to a DC motor that uses an electronic commutator to control the phase sequence of the motor, without using a brush to contact the armature. Its advantages are long life, high efficiency, low noise, stable operation and fast response, so it is widely used in high-precision application fields such as high-performance power tools and electric vehicles. Disadvantages are complex structure and high cost.

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.However, in other words, we should know more about it. 輪椅 The law of development has brought new vitality to the whole industry and revitalized the market. https://www.hohomedical.com/collections/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.
