Technical Field

[0001] This utility model relates to a chair for assistive medical treatment, specifically a psychiatric restraint device. Background Technology

[0002] The diseases covered by psychiatry are mainly mental illnesses, which are a group of neurological diseases characterized by disorders of behavior and psychological activity. Current research results suggest that these diseases are mainly caused by the interaction of external factors such as family and social environment and internal factors such as the patient's own physiological genetic factors and neurobiochemical factors, resulting in disorders of psychological activity, behavior and nervous system function.

[0003] A search of Chinese utility model patent (publication number CN220608478U) reveals a restraint chair for psychiatric use, which includes a support component, a fixing component, a handle frame, a crossbar, a backrest component, a connecting rod, a connecting rod, and a restraint strap. It uses Velcro straps to restrain the patient and is suitable for patients of different heights and body types, with good adjustability.

[0004] However, practical application has revealed that this technical solution still has at least the following drawbacks:

[0005] When Velcro straps are used repeatedly, the adhesive part can easily become contaminated with dust, hair, and other debris. This reduces the adhesive performance of the Velcro. When mentally ill patients are emotionally agitated or restless, they may try to break free of the straps, which could threaten the safety of the patient and those around them. Utility Model Content

[0014] (1) The technical scheme can accurately adjust the length of the second restraint belt by setting the pawl, the ratchet groove, the spring and the push piece, ensure that the patient's limbs are not excessively compressed while being effectively restrained, and thus provide a more personalized restraint experience. The tooth-shaped structure of the ratchet groove and the pawl cooperate with each other to effectively prevent the second restraint belt from sliding in reverse when subjected to tension, ensuring the stability of the second restraint belt, and can withstand the relatively large force generated by the patient during struggle, ensuring that the restraint device does not fail, thereby improving the reliability of the entire restraint system and preventing the patient from harming himself or others.

[0015] (2) By setting the electric push rod, the height of the seat plate can be adjusted, so that patients of different heights can find a comfortable sitting position. And the appropriate seat plate height can make the patient in a position convenient for medical staff to operate.

[0016] (3) By setting the mounting plate and the mounting block, the mounting plate can be fixed to the ground by passing the bolts through the mounting holes, avoiding the seat from falling due to the patient's struggle and twisting. At the same time, the fixed seat is also a stable operation platform, which can provide a reliable operation basis for medical staff, so that they can focus more and complete various work more accurately.

[0017] (4) By setting the handrail, the second restraint belt assembly and the second adjusting assembly, a lateral support point is provided for the patient, and the second restraint belt assembly fixes the patient's hands, and the two work together to help the patient maintain a relatively stable sitting position, which can effectively reduce the risk of falling even when the patient struggles.

[0018] (5) By setting the foot support, the third restraint belt assembly and the third adjusting assembly, a support and fixed basis is provided for the patient's feet, and further constraints are provided for the lower limb parts such as the lower leg and ankle of the patient, preventing the patient from frequently kicking, kicking and other actions due to unstable mental state, avoiding the patient from being injured due to leg activities, and also reducing the accidental injury to the surrounding medical staff, equipment or other patients caused by the out-of-control leg of the patient, ensuring the safety and order of the entire medical environment.

[0019] (6) By setting the seat cushion, the back cushion and the back pillow, the pressure on each part of the patient's body can be relieved in all directions, and the pressure points are reduced to help promote blood circulation and prevent problems such as poor blood circulation and skin tissue damage caused by long-term local pressure. A warm and comfortable medical environment is created for the patient, which can alleviate their anxiety to some extent, and make the patient feel relaxed and at ease. BRIEF DESCRIPTION OF DRAWINGS
