Technical Field
[0001] This utility model relates to the field of restraint chair technology, specifically a restraint chair for psychiatric use. Background Technology
[0002] The diseases handled by psychiatry are mainly mental illnesses, a group of neurological disorders characterized by disturbances in behavior and psychological activity. Current research suggests that these disorders are primarily caused by the interaction of external factors such as family and social environment, and internal factors such as the patient's own physiological and genetic factors and neurobiochemical factors, resulting in disturbances in psychological activity, behavior, and nervous system function. Some patients with mental illnesses are often uncooperative during treatment, which affects their treatment. To meet medical needs and prevent accidents such as injuries, scratches, or tube removal, restraint measures are used on these patients. Restraint measures are both a form of compulsory nursing care and a protective nursing behavior. Currently, traditional hospitals restrain patients with severe mental illnesses to beds or chairs during treatment.
[0003] For example, a psychiatric restraint chair with authorization announcement number CN220608478U uses Velcro straps to restrain patients, making it suitable for patients of different heights and body types. It is highly adjustable and equipped with cushions such as pads and seat cushions to improve patient comfort. However, during use, the armrests on both sides of the restraint chair are usually fixed to the chair frame, resulting in a relatively fixed distance between the armrests. This makes it difficult to adjust the distance between the armrests when restraining patients with wider bodies, resulting in a smaller space in the restraint chair when the patient is sitting, thus affecting the patient's comfort.
