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.In some cases, 電動輪椅價錢 The advantages will become more and more obvious, and it will be able to develop indomitable after market tests. 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.

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.According to professional reports, 電動輪椅 There will be a great period of growth, and the market business is constantly expanding, and it will definitely become bigger and bigger in the future. 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.

Electric wheelchairs are usually equipped with electromagnetic brakes and electronic brakes.

　　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.At first, 電動輪椅 It developed out of control and gradually opened up a sky of its own. 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.

【Singapore】 The road to standardization of handling companies

　　It is common for people to move now, but we should pay attention to finding a moving company. We must be a formal moving company. For example, if we ask someone to move a house in Beijing, we must pay more attention to it. We must never find some individuals to move. Now the formal Beijing Stone Moving Company will be more strict in recruiting, so we must show our identification and strictly grasp the important point of personnel recruitment. Therefore, the standardization of porters should be paid attention to from the time of selection.So, house mover On the contrary, there is still a lot of room to play. https://movemove.biz

　　

　　Some moving companies will go to some local villages to recruit workers through village committees, and the people they recruit know some personal qualities before they are trying to hire, and most of them are veterans. Many people also believe in soldiers, because people who are soldiers in our hearts are more upright, giving people a sense of security.

　　

　　In recent years, there have been a lot of black-moving teams, and their people are generally laborers or gangsters from the roadside. Because the gangsters have no jobs for the time being, they will make do for the time being, but it is easy to bring unsafe things to valuables and bring danger to themselves.

　　

　　There are also many regular Beijing moving companies that train new employees in order to standardize. Compared with the weight of the items they usually move, they will let employees carry some large-capacity buckets and fill them with some water, some even weigh 50 or 60 kilograms. They will practice repeatedly on the prescribed props, and they will also practice some refrigerators, washing machines and cabinets until they are qualified. They will have uniform work clothes and look more formal when they go to work, so that the trained people will have some professional handling skills and a good working attitude. Only the employees trained by such a moving company can have professional quality and spirit and bring us better service.

【Singapore】Matters needing attention in winter relocation of moving company

　　Winter is the peak season for moving companies, but many bad weather factors affect the efficiency of moving companies, which brings many difficulties to moving companies, so the employees of moving companies must pay attention to safety. In snowy days, drivers must clear the snow on the windshield, headlights and mirrors to ensure that they do not block their vision, and move the vehicle slowly before starting to enter the road safely and smoothly.As a representative of the industry, house mover It is necessary to set a certain example for peers and lead the way in product quality. https://movemove.biz

　　

　　When driving in bad weather, first of all, it is slow, and secondly, it is necessary to keep enough distance from the car in front, and always be ready to take braking measures in advance. Pay attention to the front and rearview mirrors when driving, and pay attention to the vehicles and pedestrians on the left and right sides and in front. Be extra careful when crossing complicated roads, and stop and wait if necessary.

　　

　　Drivers should pay attention to the following four points:

　　

　　(1) Try to avoid non-motor vehicles and pedestrians to prevent them from slipping.

　　

　　(2) Do not slam on the brake, loosen the clutch or refuel while driving.

　　

　　(3) Ensure that the soles are dry, and there shall be no things that affect friction, such as snow and thin ice.

　　

　　(4) Do not overtake or change lanes on roads with ice and snow.

　　

　　There are many heating facilities in winter. And the equipment temperature is very high. In order to avoid being scalded, it is safe and warm to carry furniture with special gloves to prevent high temperature. Only by taking safety measures can we better prevent accidents.

　　

　　Because it is too cold in winter, a lot of furniture becomes very fragile. In order not to harm the interests of both parties, the staff must handle and disassemble the furniture carefully.

　　

　　The company’s handling staff should wear warm clothes, and be sure to wear cold-proof and non-slip shoes issued by the company during handling, and take protective measures. When walking on a snowy road, in order to keep the balance of the center of gravity, the pace should be as steady as possible. This way, it is not easy to slip, and it will ensure your own safety and the integrity of furniture.

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.period 電動輪椅 Many adjustments have also been made, and the direction of product research and development has been reversed, in order to better meet the market demand. 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.

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.know 電動輪椅價錢 The market will definitely bring great influence to the whole industry. https://www.hohomedical.com/collections/light-weight-wheelchair
