Background technique

In recent years, the medical device market has developed extremely rapidly, especially household medical devices have become one of the fastest-growing industries in the next ten years. Compared with foreign medical industry and medical products, the level of medical products in my country is far behind developed countries. With the progress of society and the development of economy, people's self-care awareness is getting stronger and stronger, and the demand for medical equipment is gradually increasing. More medical device products are gradually coming into our family. The users of traditional medical device products are mainly medical staff, not ordinary patients. Such medical devices are not well used by patients. At present, due to the accelerated pace of life and increasing competitive pressure, the incidence of cervical and lumbar diseases is getting higher and higher. For this disease, the most effective treatment method is traction therapy. Most traction devices are limited to use in hospitals and other medical units due to their professionalism, and they need to be treated under the guidance of doctors. This is a must for severe patients; However, for mild patients, they feel that going back and forth between home and the hospital not only wastes a lot of time but also pays a certain amount of medical expenses. They often ignore treatment, and over time, minor illnesses will accumulate into serious illnesses and endanger their health.

In the treatment of cervical and lumbar diseases, there are mainly various traction devices, one part is mainly a traction therapy device loaded on the neck; the other part can stretch the cervical and lumbar spine at the same time, such as the utility model patent with application number 201120288951. Lumbar traction chair, which integrates the functions of cervical and lumbar traction, makes the patient sit and stand on the traction chair by hand (mechanical) or button (electric) to achieve not only cervical traction, but also lumbar traction. When lumbar traction You can sit and stand on the traction chair, or you can lay the back of the chair flat and lie flat on the traction chair for lumbar traction. Another example is the utility model patent with the application number of 201020603098.7: a foldable cervical and lumbar manual traction chair, which is simple in structure and easy to operate, which is convenient for patients to manually apply force and can stretch and maintain the patient's entire spine. It can be folded and retracted, occupying little indoor space. However, the treatment effect of the first type of device is not obvious for the user, and it can only treat the cervical spine, and cannot take into account the lumbar spine, so the overall treatment effect cannot be achieved; although the second type of device can stretch the cervical and lumbar spine at the same time, the traditional head The internal traction device is an occipital-mandibular traction belt, which is not conducive to fixing the position of the head and cervical spine. At the same time, the traditional backrest is a whole piece, which is not conducive to reducing the pressure on the spine.

There is an urgent need in the market for a cervical and lumbar traction chair that not only helps to fix the position of the head and the cervical spine, but also reduces the pressure on the spine.
