Description

Technical Field

[0001] The invention relates to the technical field of medical restraint chairs, in particular to a restraint chair for mentally ill patients. Background Art

[0002] The diseases involved in psychiatry are mainly mental illnesses, which are a group of neurological diseases characterized by disorders in behavior and psychological activities. Under the control of pathological psychology, there are actions such as suicide, aggression, and harming others. Generally, hospitals need to restrain and control the actions of such patients during the onset of the disease.

[0003] The restraint chairs currently used in the market can have the patient's feet all touching the ground, which can leverage the force to make the restraint chair shake as a whole, resulting in instability. In addition, the time of the patient's onset is random. When the patient has an onset, the patient needs to be restrained and transferred to a ward or treatment room. During this process, traditional restraint chairs are not convenient to transfer. Even if some restraint chairs are equipped with universal wheels, during the transfer process, the patient's large-scale struggle will cause the restraint chair to shake continuously, which is easy to tip over and cause harm to the patient. For this reason, we propose a restraint chair for mentally ill patients. Summary of the Invention

[0004] One of the technical problems to be solved by the present application is that the traditional restraint chair is inconvenient to transfer and is easy to fall over when the patient struggles.

[0005] To solve the above technical problems, the present invention provides a restraint chair for mentally ill patients, comprising a restraint chair body and a restraint belt mounted on the restraint chair body.
