Description

Medical electric diagnosis and treatment bed with multiple body positions

Technical Field

The invention belongs to the field of medical auxiliary instruments, and particularly relates to a multi-position medical electric diagnosis and treatment bed.

Background

The medical electric diagnosis and treatment bed is a device for lying a patient and can also be used for health care treatment such as common massage, so that the medical electric diagnosis and treatment bed belongs to common diagnosis and treatment instruments in places such as hospitals, diagnosis and treatment hospitals and beauty parlors.

At present, doctors and therapists need to perform functions of multi-angle traction, deflection (or steering), vibration and the like on a medical electric diagnosis and treatment bed in order to conveniently diagnose and treat patients.

However, during the adjustment process of the arm, it mainly involves the rotary up-and-down movement and the rotation around the vertical direction (outward opening and inward closing) to meet the diagnosis and treatment needs of the patient, but most of the up-and-down movement is set in different steps, and different heights are presented at different steps, so that the steps of the fixed setting are not necessarily suitable for each patient, and therefore, the universality is poor.

In the process of head rotation, the head does not only need to swing left and right in the horizontal direction, but also needs to move horizontally, tilt upwards and turn downwards, so that the diagnosis and treatment needs can be met, and therefore, the common adjusting mechanism is difficult to have the function at the same time.

In the process of rotation of the leg support, the leg support can be turned up and down or swung left and right in general, but the motion relationship between the leg support and the leg support is relatively independent and is not related to each other, so that the rotation adjustment of the leg support is difficult to realize.
