  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.precisely because 電動輪椅 The rapid development of, so also brought new opportunities to the industry. 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.

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.In addition to these aspects, 電動輪椅價錢 The performance in other aspects is also relatively good, which has attracted everyone’s attention and research. https://www.hohomedical.com/collections/light-weight-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.

Controller is the core component of 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.In addition to domestic, 電動輪椅 It has also emerged in the international field and gradually gained the favor of more foreign friends. 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.

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.On the other hand, 電動輪椅 It also brings tangible benefits to everyone and feels useful. It is a model of the industry. https://www.hohomedical.com/collections/light-weight-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.

Armed conflict in southern Mexico kills 11 people_ prosecutors open investigation

At first, My WordPress It developed out of control and gradually opened up a sky of its own. https://gjsign.com

Mexico City, May 14 (Reporter H Wu Hao) Prosecutors in the southern Mexican state of Chiapas issued an announcement on social media platforms on the 14th that an armed conflict occurred in the city of Chico Musello that day, killing at least 11 people.

The announcement said that prosecutors had launched an investigation into the parties to the conflict and confirmed the identity of the deceased through an autopsy. At the same time, relevant parties patrolled the area to maintain security and order.

According to local media reports, the armed conflict occurred because drug cartels in the Mexican states of Naloa and Jalisco seized control of the border area of Chiapas. The conflict also caused damage to local power facilities and caused power outages in many communities.

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.This means that 電動輪椅價錢 It is the weather vane of the industry and can bring people great self-confidence. 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.

There are 61 women victims of South Korea_s second _Room N_ incident. The two main offenders graduated from Seoul National University

More importantly, put My WordPress It is imperative for us to make thorough analysis and maximize its social function. https://gjsign.com

The second Room N incident broke out at Seoul National University in South Korea. According to South Korean media reports on May 22, as of now, as many as 61 female victims have been confirmed, including 12 students at Seoul National University.

The Seoul Police Department has so far arrested five gang suspects, two of whom are graduates of Seoul National University. They are suspected of making and privately spreading them on the instant messaging software T from July 2021 to April this year. Pornographic photos or videos synthesized using deep counterfeiting technology.

According to the police, in the process of arresting the main offender Park, the private reporting group Tracking Group Sparks, which first reported the incident in Room N five years ago, provided decisive assistance. Yuan Enzhi, who was in the pursuit team, disguised himself as a male, entered the private live broadcast room to lurk for two years, and contacted Park. This year, he lured Park to meet offline to help the police successfully capture him.
