Description

Technical Field

[0001] The utility model relates to the technical field of restraint belts, in particular to an inflatable wheelchair restraint belt with an alarm function to prevent it from falling off. Background Art

[0002] Restraint protection, also known as protective restraint, refers to a mandatory medical protection measure that is urgently implemented by medical staff in the process of psychiatric treatment to maximize the restriction of the patient's behavior and activities according to the special circumstances of the patient's condition. It is one of the methods of psychiatric treatment and care for such special patients, and the purpose is to minimize the harm to patients caused by other unexpected factors. Some patients in wheelchairs need to use restraint belts for restraint protection. The existing patent, patent announcement number CN212089891U, discloses a wheelchair restraint belt, including a waist guard belt, a first strap, a second strap, a strap buckle, a hollow hole, a buckle mounting part, a first buckle, a nylon rope, a crotch guard belt, a second buckle, a heating lining, a cotton cloth layer, a first reinforcement layer, a heating plate and a second reinforcement layer. The utility model comprises an anti-falling mechanism. When some people with severe behavioral disabilities such as those with lower limb paralysis sit in a wheelchair, the first buckle of the anti-falling mechanism is buckled on the buckle mounting part of the waist guard belt, and the second buckle is buckled on the wheelchair under the patient's legs. At this time, under the action of the crotch guard belt, the patient can be effectively prevented from falling downward, which is beneficial to the fixation of people with severe behavioral disabilities such as those with lower limb paralysis. The device has a simple structure and is relatively convenient to use. The waist tightening mechanism of the utility model comprises a heating lining. When the heating lining is working, the stomach of the patient using the wheelchair can be kept warm, which is beneficial to relieving the gastrointestinal discomfort of the patient.

[0003] Regarding the above-mentioned related technologies, the inventors believe that the following defects exist: in actual application, since the restraint belt will loosen during use, subsequent nursing staff need to check it frequently and cannot promptly know the looseness of the restraint belt, which will cause unsafety during the nursing process and the movement of the wheelchair, thereby reducing the convenience of using the restraint belt. Therefore, we propose an inflatable anti-slip wheelchair restraint belt with an alarm function to solve the above-mentioned problems. Utility Model Content
