Description

Adjustable restraint chair of psychiatric department

Technical Field

The invention relates to the technical field of medical instruments, in particular to an adjustable constraint chair for a psychiatric department.

Background

The restrictive protection means a medical protection measure which is applied by medical staff to the specific condition of the patient's condition in the psychiatric medical process and forcibly limits the behavior and activity of the patient to the maximum extent, and is one of the methods for treating and nursing the specific patient in the psychiatric medical process, and aims to reduce the harm of other unexpected factors to the patient to the maximum extent.

Most of the existing restraint chairs simply fix the hands and feet of the patient on the handles and the chair legs of the restraint chair, and then fix the chest part of the patient by using the transverse plate, but because the psychiatric patient basically has no independent consciousness, when the restraint chair is used for restraining the action of the patient, most of the restraint chairs fix a universal wheel at the bottom, because the contact area of the universal wheel and the ground is small, and the amplitude of the shaking generated by the patient per se is easy to make the restraint chair unstable and even topple over, thereby causing the injury of the patient, and most of the restraint chairs are only simple wood, after the patient sits on the restraint chair for a long time, the hands and feet of the patient are easy to tingle, even the blood is not circulated, thereby causing the injury of the body of the patient, and the existing restraint chairs are the conventional wooden chair reconstruction, which can damage the spine and the hip bone of the patient when sitting for a long time, a psychiatric adjustable restraint chair is therefore proposed to address the above mentioned problems.
