Description

Technical Field

[0001] The invention belongs to the technical field of rehabilitation medical equipment, and in particular relates to a device for assisting patients in turning over and transferring. Background Art

[0002] At present, more than 13% of the population in my country has reached the age of 60 and the number is still increasing. With the increase of age, the risk of many diseases is also increasing. At an advanced age, many elderly people have varying degrees of disability. According to relevant statistics, there are more than 30 million patients in my country with varying degrees of disability. The most common disability is the inability to move autonomously and turn over in bed. Long-term bed rest can cause damage to some other physiological functions. Since the patient cannot move autonomously, the continuous pressure on the same part of the body will cause poor blood circulation and nerve damage, which will cause local necrosis of the part and form bedsores. Therefore, it is particularly important to help patients turn over frequently.

[0003] Compared with the huge number of patients, my country's medical resources are stretched. Moreover, helping patients turn over places a great physical burden on nursing staff. Most of the existing medical beds in my country are low-priced, low-tech and single-function bed products. They do not have automatic and efficient patient care functions. Summary of the invention

[0004] The purpose of the present invention is to overcome the defects of the existing hospital beds in the prior art that the existing beds have a single function and require the patient to turn over the body manually, and to provide a device installed on the left and right sides of the hospital bed that can assist the patient in turning over and transferring.
