Description

Medical bed jacking part

Technical Field

The utility model relates to the field of medical equipment, concretely relates to medical bed.

Background

In the process of patient treatment, the transportation of the patient is an essential link in the examination, diagnosis and treatment processes, and comprises the step of moving the patient from a sickbed to a stretcher or from an operating room and an examination room to the sickbed. The requirement of not changing the posture of the patient is very common. However, in the traditional transfer process, the body parts of the patient can be changed by the actions of holding, lifting and the like of the carrying personnel, such as bending, stretching, side position and the like, and a series of passive actions can affect the patient, so that the pose of the patient is changed, the pain is aggravated, the operation is careless, the secondary damage is more easily caused, and the life is threatened. Especially, the side injury is caused to patients who are not suitable for excessive change of body postures such as early cerebral hemorrhage, spine fracture, postoperation and the like. In addition, in the traditional transfer process, due to the fact that people are disorderly and disorderly, if force is unbalanced in the transfer process, actions are not coordinated, or the hands are not enough to injure the patient again.
