step two: medical personnel control the miniature electric telescopic rod, utilize it to retrieve the extension rod, pull the end picture peg away from the notch, and then the ejecting spring pushes out the locking inserted block out of the receiver, medical personnel can pass the patient's shank or bottom side of shoulder with the one end that the restraint strap body connects with the locking inserted block, and insert the locking inserted block into fixed block again, utilize the clamping mechanism to fix one end of the restraint strap body;

step three: medical personnel place an air cavity cushion with one side connected with an external high-pressure air bag on the inner side of the restraint belt body, and control the servo motor to rotate reversely to tighten the restraint belt body and realize restraint treatment on common patients by matching with a rubber abutting block on one side of the storage box; when a patient struggles violently, on one hand, the constraint belt body can be tensioned, and then the stress of the torque sensor is increased, on the other hand, the patient struggles, and the sickbed can shake back and forth, so that the storage box shakes, and the magnetic metal hanging ball at the bottom end of the hanging rope breaks away from the constraint of the magnetic block, so that the magnetic metal hanging ball swings back and forth, and further the touch switch is triggered, meanwhile, under the condition that the stress of the torque sensor is increased, the servo motor is controlled to be started to further rotate, the constraint belt body is tightened, and meanwhile, the electric control air valve is controlled to be opened, so that the external high-pressure air bag is utilized to blow air into the air cavity cushion, and the air cavity cushion is expanded, so that the constraint;

step four: the utilization sets up in the dry granule of receipts area chamber roller inner wall, utilizes the cavity of receiving area chamber roller surface convex arc board and the restraint area body and constituting, and the cooperation sets up opening one, opening two guarantee that the restraint area body is in dry environment all the time, avoid weing to breed mould.
