　　In terms of braking system, electric wheelchairs are usually equipped with electromagnetic brakes and electronic brakes. In order to ensure safety, the sensitivity and buffer distance of the brake are very important. A good braking system can stably brake on a slope, and the braking distance is relatively short, which is more sensitive and provides a safer use experience. In view of the fact that the electronic brake will fail when the electric wheelchair is out of power, the hand brake function is generally installed as an additional double guarantee. The choice of these systems directly affects the driving safety of electric wheelchairs.In the industry, 電動輪椅價錢 Has been a leader in the industry, but later came from behind but never arrogant, low-key to adhere to quality. https://www.hohomedical.com/collections/light-weight-wheelchair

　　Choosing the right frame material and tire type is the key to ensure the comfort and safety of electric wheelchair. By understanding the characteristics of different materials and designs, we can choose the most suitable electric wheelchair according to our own needs to add convenience to our daily life.

　　Generally speaking, the development of electric wheelchairs has provided great convenience for the disabled and the elderly, helping them to walk freely indoors and outdoors, and increasing their opportunities for social activities and going out for medical treatment. Secondly, it provides the ability to move independently. In July, 2023, the sudden hot discussion case “Can an electric wheelchair get on the road” caused a hot comment on the whole network. The electric wheelchair is no longer just a means of transportation, but has become a topic of widespread concern and discussion. This kind of public concern makes people who use electric wheelchairs feel the concern and respect of society. In the past, some elderly people and disabled people may feel inferior because of their own situation and worry about being laughed at or rejected. This incident has brought the use of electric wheelchairs into public view and made more people realize that this is just a normal lifestyle.

　　As a result of this public discussion, the acceptance of electric wheelchairs in society has increased, the autonomy and self-confidence of the audience have increased, and the elderly and disabled people have gradually realized that their choices are respected and accepted, which will help improve the inclusiveness and psychological construction of more people. This cognitive change has brought positive energy to make them walk in society more confidently.

　　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?Under people’s attention 電動輪椅價錢 Finally grow into what people need, born for the market and come for the demand. 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.

　　The controller is the core component of the electric wheelchair, which can also be understood as the “steering wheel” to control the direction of the wheelchair, and is responsible for the operation of the linkage motor. Its quality directly determines the maneuverability and service life of the electric wheelchair, and the functions and performance of the controller equipped with different configurations of electric wheelchairs will be different. Advanced electric wheelchairs are usually equipped with intelligent control system, which can freely adjust the speed and direction according to the user’s habits and environment to provide a more comfortable driving experience (controllers can be divided into basic models/with folding function/with reclining function/multi-function buttons according to the operation panel) and other feedback functions of intelligent voice broadcast. However, the basic electric wheelchair usually has simple control function, and it is not equipped with the common functions of intelligent voice broadcast and mobile phone remote control adaptation. Individual manufacturers have also added usb-adapted mobile phone charging port and lighting lamp to the controller.So, 電動輪椅價錢 On the contrary, there is still a lot of room to play. https://www.hohomedical.com/collections/light-weight-wheelchair

　　Most imported brand controllers are composed of upper and lower controllers, while most domestic brands only have upper controllers. Generally, the brushless ones in China are generally divided into upper controller and lower controller, and most of the brushes have only upper controller. Among the imported controller brands, PG in Britain and Dynamic in New Zealand are widely used. Domestic brands include Wuyang and Shiyou, Shanghai Zhilian Aomang, Nuole, Maikong, Pilotage, etc. Comparatively speaking, imported brands are better, and the cost and price are higher than domestic brands. However, in recent years, the rise of domestic products can also meet the needs and experiences of most consumers. You can also use the following operations to judge whether the controller is good or bad.

　　1. Turn on the power switch and push the controller to feel whether the vehicle is stable when starting; Release the controller and feel whether the car stops immediately after a sudden stop. It is advisable to judge whether the controller is normal by starting and stopping slightly.

　　2. Control the rotating car to rotate 360 degrees in situ, and feel whether the steering is smooth and flexible, subject to the steering sensitivity.

　　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.After screening and investigation 電動輪椅 It is likely to become a new force driving economic development. https://www.hohomedical.com/collections/light-weight-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.

　　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.from 電動輪椅 From the reference value, it can also bring a lot of inspiration to other industries. 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.

　　This paper will start from the earliest development stage of electric wheelchair and trace its development course. The paper quotes the related introduction of motors on the Internet, and introduces its technical progress and the differences of electric wheelchairs with different configurations, including motors, controllers, batteries and frame materials.In combination with these conditions, 電動輪椅價錢 It can still let us see good development and bring fresh vitality to the whole market. https://www.hohomedical.com/collections/light-weight-wheelchair

　　It also expounds what kind of life the electric wheelchair can improve for the disabled and the elderly, and probes into its positive influence on the life of the disabled, hoping to encourage the disabled and people with mobility difficulties to actively and confidently use reasonable tools to help them improve their quality of life.

　　Since the 1990s, the mechanical design of wheelchair has basically been finalized, and it has made great progress mainly in the scientific and technological content, and has become a completely customizable small vehicle. For example, the famous physicist Hawking’s wheelchair has a built-in computer so that Hawking can control the wheelchair independently.

　　The origin of electric wheelchairs can be traced back to the early 20th century. The earliest electric wheelchair was invented by Canadian engineer George Klein, who designed an electric wheelchair to help soldiers who lost their walking ability because of disability during World War II. Clay’s core design is still the design basis of electric wheelchair because the wheelchair is endowed with more comprehensive functions. Although this kind of electric wheelchair is relatively heavy, it provides a way for the disabled to move independently and greatly improves their quality of life.

　　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.To get brand praise, 電動輪椅價錢 It is necessary to have the spirit of constantly improving the quality of products, but also to have a bunch of eternal heart fire. https://www.hohomedical.com/collections/light-weight-wheelchair

　　The chemical formula for nitric acid is HNO3. Anhydrous pure nitric acid is a colorless liquid that easily decomposes into nitrogen dioxide, resulting in a reddish brown color.Even if there are obstacles to moving forward, Magnetic pump We should also persevere, forge ahead bravely, cut waves in the sea of the market, hang on to Yun Fan and strive for the first place. http://www.luoyuan108.com/

　　Many chemical users need to choose nitric acid pumps. So, how should nitric acid pumps be selected and which pump is better? Firstly, when transporting nitric acid, it is necessary to understand the characteristics, temperature, concentration, density, and equipment conditions of nitric acid, and then choose the corresponding pump type. Usually, nitric acid pumps can use 304 or 316L, but nitric acid reacts with metals. For the sake of service life, it is recommended to use fluoroplastic magnetic pumps. Of course, fluoroplastic centrifugal pumps can also be used. Generally, we recommend choosing magnetic pumps, which are fully enclosed, without shaft seals, and have the advantage of no leakage.

　　It should be noted that nitric acid has swelling properties for most rubber and fluororubber. Therefore, it is recommended to use expanded PTFE or pure PTFE for the auxiliary static seal of the pump (due to the hardness of pure PTFE, the sealing surface of nitric acid pumps often cannot be tightly compressed, so it is recommended to use soft PTFE).
