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.In the eyes of industry experts, 電動輪椅價錢 Indeed, it has great development potential, which makes many investors more interested. 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.

　　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 order to facilitate users to have a better experience, 電動輪椅 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/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.

　　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.The data shows that, 電動輪椅價錢 Its development potential should not be underestimated, and it is also the inevitability of its existence. https://www.hohomedical.com/collections/light-weight-wheelchair

　　Front wheel and rear wheel: The design of front wheel and rear wheel of electric wheelchair directly affects its flexibility and shock absorption. Usually, an electric wheelchair has four wheels, two of which are front wheels (universal wheels) and the other two are rear wheels (driving wheels). The smaller the front wheel, the more flexible the wheelchair is, which is suitable for turning flexibly in a narrow space. However, the smaller front wheels are easy to fall into ditches or ground cracks when facing them, which affects the driving experience. In addition, the size of the front wheel also affects the climbing ability of the electric wheelchair. The larger front wheel makes it easier for the wheelchair to climb the stairs, which makes it more convenient for users in their daily lives.

　　Shock absorption: the choice of tires is also very important in shock absorption. The tires of electric wheelchairs are usually divided into pneumatic tires and solid tires. Pneumatic tires have good shock absorption, and it is not easy to feel bumpy when passing through ditches and ridges, while solid tires will feel strong shock when facing uneven roads. In addition, some electric wheelchairs are equipped with special shock absorbers, which makes the driving more stable. These designs not only improve the comfort of wheelchairs, but also make users safer when they are outdoors.

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

Moscow, July 15 (Reporter Jiang Youlin) According to information from the Russian Ministry of Defense on the 15th, Russia’s spring conscription work has ended this year. A total of 150,000 people have been recruited and sent to the Russian armed forces and other military formations.

The Russian Ministry of Defense posted a message on social media that day that Russia’s various conscription committees started work on April 1, and the dispatch of conscripts began on April 15.

In order to ensure military transportation, 15 Russian armed forces aircraft flights, 14 military echelons, 172 civil aviation flights, multiple passenger trains and military road transport vehicles participated in this conscription work.

As a rule, Russia recruits soldiers once every year in spring and autumn. About 1.47 million people will be recruited into the army in the spring of 2023, and 130,000 people will be recruited into the army in the fall of 2023.

　　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.Today, people are interested in 電動輪椅 There are also many dependencies, and the expectations for products are getting higher and higher. 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.

So we can draw a preliminary conclusion, My WordPress It is helpful to the needs of the industry market and social development. https://gjsign.com

According to a BBC report on the 20th, researchers at the University of Amsterdam in the Netherlands said at a medical conference held on the 18th that they successfully removed the HIV virus (HIV) from infected cells using CRISPR gene editing technology.

Screenshots of related reports

It is reported that although existing drugs can prevent the HIV virus from further penetrating into the human body, they cannot clear the existing virus in the patient’s body. Even if patients receive effective treatment and the HIV virus in their bodies enters a dormant or latent state, they still carry HIV DNA or genetic material.

According to the BBC, the CRISPR gene editing technology used by the researchers is similar in principle to scissors, which can remove or inactivate HIV-infected cells by cutting DNA. This gene editing technology won the 2020 Nobel Prize in Chemistry.

At present, the scientific research process at the University of Amsterdam is still in the proof-of-concept stage, and it will take a long time for it to be truly applied to AIDS treatment.

Scientists believe that if this new technology can be further developed, it will be expected to eliminate all HIV in the human body, thereby curing AIDS. However, some virologists also said that the possible off-target effects and long-term side effects of this technology are worrying.

　　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.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

　　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.
