[0016] 1. The utility model is an automatic induction inflatable medical restraint belt, which can ensure the scientific rationality of the tightness of the restraint. It can effectively restrain patients, help nurses accurately adjust the tightness of the restraint within an appropriate range, and directly put it on the wrist for restraint, avoiding secondary damage to the patient's skin caused by damage to the indwelling needles and other treatment items on the back of the hand and foot;

[0017] 2. The utility model is an automatic induction inflatable medical restraint belt, which can facilitate the operation of medical staff. After the restraint belt is put on, it can be restrained by automatically contracting, without the need for two hands to operate the binding. The fixing belt part adopts a connecting buckle method, which is convenient for medical staff to directly fix the restraint belt to fixed objects such as bed handles, and the distance between the restraint part and the fixed object can be controlled by adjusting the length of the fixing belt;

The restraint belt contains an airbag part in the middle. After the airbag is deflated, there is a certain gap between the wrist and the patient, which is convenient for blood circulation in the patient's wrist. At the same time, the gas in the slightly deflated airbag after deflation forms a wider contact surface, avoiding direct contact between the patient's wrist and the bed unit. By increasing the contact area and reducing the pressure, pressure injuries on the patient's wrist can be prevented.

[0019] 4. The utility model is an automatic induction inflatable medical restraint belt, which can increase the patient's comfort and reduce the cost of use. The strap and the airbag are both covered with skin-friendly outer covers to increase the patient's comfort. At the same time, the outer covers can be disassembled, cleaned, disinfected and reused repeatedly, reducing the cost of clinical use. BRIEF DESCRIPTION OF THE DRAWINGS

After the power is activated, the display screen 17 shows the constraint tightness value, and the value range is 2cm-3.5cm (refer to the average width of the index finger and middle finger of Chinese adult men and women). Each time the interval "+" or "-" sign on the display screen is pressed, the constraint tightness value increases or decreases by 0.1cm. Medical staff can set the specific constraint tightness value within the numerical range according to the actual situation of the patient, and start the constraint belt after the setting is completed.

[0042] The utility model sets the minimum tightness range of the restraint, activates the inductive airbag, and automatically identifies the wrist circumference by inflating the airbag, and then controls the deflation of the airbag to maintain the tightness range of the restraint. It solves the problems of inconvenience of single-person operation by nurses in clinical restraint, complex installation of restraint tools, and difficulty in controlling the accuracy of restraint tightness. The restraint belt adopts a soft, detachable, reusable and skin-friendly outer material, which increases comfort while reducing the cost of use.
