As a device to assist people with mobility problems and disabled people in their movement, electric wheelchairs are an essential means of transportation for people with disabilities. They have a wide range of applications and can be used in hospitals and homes. Therefore, its electrical performance, safety performance and electromagnetic compatibility. Very important. With the improvement of electronic integration, there are many types of wheelchairs, even if they have electronic speed governors, electronic differential steering, electric power steering and manual brake control.
According to the usage scenario, it can be divided into indoor type, indoor and outdoor universal type and outdoor type.
According to the "Medical Device Classification Catalog", electric wheelchairs belong to the second category of medical devices, and China has introduced relevant policies to promote the development of the industry. In 2021, policies related to rehabilitation medicine will be intensified again. To further expand the scope of rehabilitation medicine, the "Opinions on Accelerating the Development of Rehabilitation Medical Work" and the "Notice on Conducting Pilot Work on Rehabilitation Medical Services" were issued. pilots and improve the rehabilitation medical services system.
Electric wheelchairs are modified and upgraded based on traditional manual wheelchairs by superimposing high-performance electric drive devices, intelligent control devices, batteries and other components. Equipped with artificially controlled smart controllers, they can propel the wheelchair forward, backward and turn. The generation of smart wheelchairs with multiple functions such as standing, lying down, etc. It is a high-tech product that combines modern precision machinery, intelligent CNC, engineering mechanics and other fields. Upstream raw materials for electric wheelchairs include steel, electronic components, integrated circuits, hardware, wires and cables, etc. The downstream raw materials are mainly middle-aged and elderly people and people with leg disabilities.
The electric wheelchair was invented at the beginning of the 20th century. The United States issued the first patent certificate for an electric wheelchair in 1940. Because early products were bulky, expensive, inefficient, and unreliable, they received little attention. With the advancement of technology, the design of electric wheelchairs is becoming more sophisticated. Power wheelchair designs are becoming lighter and have small wheels. They are suitable for indoor activities, can be used in public places, and can also handle unstable and bumpy roads. In the foreign electric wheelchair market, the United States and Japan have the greatest advantages, their scientific research and technology are quite mature, and the purchase volume in the market has also shown a relatively stable state. Common manual wheelchairs are slowly being removed from the scene. Data shows that the global electric wheelchair market size was $1,812 million in 2015 and will increase to $3,588 million by 2022.
Currently, Topmedi electric wheelchairs can be used on slopes, curbs, steps, potholes and other road conditions.
