[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1-5 , a restraint device, comprising: a bed board 1 and a body restraint component 2. The body restraint component 2 includes a chest restraint band 21 fixed on the bed board 1, a shoulder restraint band 23, a connecting buckle 22 for connecting the chest restraint band 21 and the shoulder restraint band 23, a connecting band 27 fixed on the bed board 1, a wrist restraint band 25 woven and connected to the connecting band 27 through a braided wire, and a soft pad cover 24 sleeved on the shoulder restraint band 23; a waist restraint band 3 and an ankle restraint band 31 are respectively arranged on the bed board 1. The ankle restraint band 31 is also fixedly connected to the bed board 1 through the connecting band 27. One end of the wrist restraint band 25 is provided with a hook surface part of a magic tape, and the other end is provided with a magic tape surface part matching the hook surface part. The structural design of the ankle restraint band 31 is the same as that of the wrist restraint band 25, that is, one end of the ankle restraint band 31 is also provided with a hook surface part of a magic tape, and the other end is also provided with a magic tape surface part matching the hook surface part, so that both ends of the ankle restraint band 31 and the wrist restraint band 25 can be connected to each other through the provided magic tape parts, thereby realizing the function of fastening the two ends together, and thus forming an adjustable-size annular structure to meet the actual restraint requirements. The side of the soft pad cover 24 adjacent to the patient is provided with a buffer pad 26, which is used to reduce the pressure on the patient's skin and provide additional comfort. Moreover, the edge of the buffer pad 26 is smoothly wrapped with cloth to reduce the irritation and friction to the patient's skin and improve the safety and comfort of use.

[0023] An adjustment assembly 4 is further provided on the bed board 1. The adjustment assembly 4 includes a winding roller 43 fixedly connected to the end of the shoulder restraint strap 23, a connecting shaft 44 rotatably arranged inside the bed board 1 and fixedly connected to the winding roller 43, a turntable 41 fixedly installed on the end face of the bed board 1 through which the connecting shaft 44 passes, and a crank 42 slidably arranged on the turntable 41. The adjustment assembly 4 further includes a friction plate 45, a connecting rod 46, a first ball head rod 47, a connecting seat 48, a first spring 49, a second ball head rod 410, a slider 411 and a second spring 412. The friction plate 45 is fixedly connected to the first ball head rod 47 through the connecting rod 46. The first ball head rod 47 is slidably arranged inside the connecting shaft 44. The connecting seat 48 is fixedly installed on the first ball head rod 47. The two ends of the first spring 49 are respectively fixedly connected to the connecting seat 48 and the connecting shaft 44. The second ball head rod 410 is fixedly installed on the crank 42. The slider 411 is also fixedly connected to the crank 42. The two ends of the second spring 412 are respectively fixedly connected to the slider 411 and the turntable 41. A chute for passing through the connecting rod 46 is formed on the connecting shaft 44, and the matching relationship between the connecting rod 46 and the chute is clearance fit. The shape and size of the chute are designed to allow the connecting rod 46 to pass through and slide along it in a clearance fit manner. Specifically, there is a certain gap between the inner wall of the chute and the outer surface of the connecting rod 46. This gap not only ensures that the connecting rod 46 can slide smoothly in the chute but also avoids problems such as jamming or wear caused by too tight a fit. In the initial state, the crank 42 is located at the center of the turntable 41, and the ball head end of the second ball head rod 410 contacts the ball head end of the first ball head rod 47.

[0024] When adjusting the length of the shoulder restraint strap 23 according to the working principle, the crank 42 is pushed to slide on the turntable 41, so that the crank 42 is located on the side of the center of the turntable 41. The second ball head rod 410 fixed on the crank 42 no longer contacts the first ball head rod 47, and the first ball head rod 47 loses its restriction. Also, since the connecting seat 48 fixed on the first ball head rod 47 is further connected to the connecting shaft 44 through the first spring 49, the entire first ball head rod 47 will slide towards the crank 42 under the action of the first spring 49. The friction plate 45 fixedly connected to the first ball head rod 47 through the connecting rod 46 rotates synchronously. At this time, the friction plate 45 no longer contacts the bed board 1, and the turntable 41 and the connecting shaft 44 are fixedly connected. After driving the turntable 41 to rotate through the crank 42, the connecting shaft 44 rotates synchronously. The winding roller 43 fixed on the connecting shaft 44 is also fixedly connected to the end of the shoulder restraint strap 23. Therefore, after the connecting shaft 44 drives the connecting shaft 44 to rotate together, the shoulder restraint strap 23 will be wound on the winding roller 43, thereby changing the length of the part of the shoulder restraint strap 23 extending out of the bed board 1, so as to be suitable for patients of different body types. Then, when the crank 42 is released, the slider 411 fixed on the crank 42 is further connected to the turntable 41 through the second spring 412. Then, under the action of the second spring 412, the crank 42 is pushed back to the center position of the turntable 41, and the second ball head rod 410 will squeeze the first ball head rod 47 through its ball head end, so that the first ball head rod 47 slides towards the bed board 1 until the friction plate 45 contacts the bed board 1 again. At this time, under the action of the friction lines on the surface of the friction plate 45, a certain frictional force can be generated between the friction plate 45 and the bed board 1, thereby restricting the rotation of the friction plate 45, and further restricting the rotation of structures such as the connecting shaft 44 to lock the length of the shoulder restraint strap 23.

[0025] During actual restraint, both chest restraint straps 21 are fixedly connected to the bed board 1, and the two chest restraint straps 21 are also connected by Velcro. Therefore, the two chest restraint straps 21 can be overlapped with each other, and their states can be fixed through Velcro, thereby restraining the patient's chest. The female seat of the connecting buckle 22 is fixed on the chest restraint strap 21, and the male seat of the connecting buckle 22 is fixed on the shoulder restraint strap 23. Inserting the male seat on the shoulder restraint strap 23 into the female seat inside the chest restraint strap 21 can restrain the patient's shoulder area. The connection principle of the two waist restraint straps 3 is similar to that of the two chest restraint straps 21. The two waist restraint straps 3 are overlapped with each other, and their states are fixed through Velcro, thereby restraining the patient's waist. The ankle restraint strap 31 and the wrist restraint strap 25 have the same structure, and are also band-shaped designs, and Velcro is provided on their surfaces to form a circular structure to respectively restrict the patient's ankles and wrists. And both the ankle restraint strap 31 and the wrist restraint strap 25 are connected to the connecting strap 27 through braided lines, and the connecting strap 27 is fixed on the bed board 1. Therefore, the restraint effects of the ankle restraint strap 31 and the wrist restraint strap 25 are achieved.

[0026] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
