The same figure marks in the drawings represent the same components. It should be noted that the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0019] Reference Figure 1 An embodiment of the present invention provides a restraint device for patients with postoperative delirium, comprising a bed 1, on which four groups of adjustment components 2 are arranged in mirror image, a limb restraint component 3 is arranged on the upper end of the adjustment component 2, a headrest 4 is arranged in the middle of one side of the bed 1, and two restraint belts 5 are arranged in the middle of the upper end of the bed 1, and the other ends of the two restraint belts 5 are connected by a strap buckle.

[0020] By installing the limb restraint component 3 and the restraint belt 5, the patient's limbs and torso can be restrained, ensuring that the patient can be fully restrained, which greatly improves the practicality of the device.

[0021] Reference Figure 2 The adjustment component 2 includes a T-shaped slide 21 reserved on the bed 1, a screw 22 is screwed into the T-shaped slide 21, and a T-shaped slider 23 is screwed onto the screw 22. The T-shaped slider 23 is movably installed in the T-shaped slide 21, and the upper end of the T-shaped slider 23 is fixedly connected to the support block 24, and the support block 24 is connected to the limb restraint component 3. One side of the screw 22 passes through the bed 1 and is fixedly connected to the handle 25.

[0022] When restraining a patient, first place the patient on the bed 1, rotate the handle 25, and the handle 25 pulls the screw 22 to rotate. The screw 22 causes the T-shaped slider 23 to slide in the T-shaped slot 21, and then adjusts the orientation of the limb restraint component 3 to ensure that the limb restraint component 3 can restrain the corresponding limb, reducing the limitations of the use of the device.

[0023] Reference Figure 3-10 The limb restraint assembly 3 includes a pair of mirror-image arch blocks 31, each of which is provided with an arch pad 32. The patient's hands or legs are restrained via the arch pad 32. The arch pad 32 is fixed to a plurality of rubber strips on the side farther from the arch block 31. The rubber strips are arranged parallel to the arch block 31 to enhance the obstruction between the arch pad 32 and the restraint part, thereby enhancing the reliability of the arch pad 32 in fastening the restraint part. The two sides are respectively fixedly connected to a protrusion A33 and a protrusion B34. The protrusion A33 is provided with an engaging post 35. The protrusion B34 is fixedly connected to an engaging platform 36 for constraining the engaging post 35 to engage. The engaging posts 35 on the pair of protrusions A33 are respectively engaged with the engaging platforms 36 on the pair of protrusions B34, completing the initial fastening of the pair of arched blocks 31. The device also includes an adjusting unit for adjusting the pair of arched pads 32 together. The adjusting unit is assembled inside the arched block 31.

[0024] The control unit includes an arch frame 37 screwed into the arch block 31. The circumference of the arch block 31 is smaller than that of the arch frame 37. When the pair of arch blocks 31 are close to each other, the two sides of the pair of arch frames 37 can be pressed against each other. When the user rotates one of the arch frames 37, the other arch frame 37 can be pressed along the inside of the arch block 31 through the arch frame 37. Both sides of the arch frames 37 are fixed with magnets 330 so that the two sides of the pair of arch frames 37 are attracted to each other. The inside of the arch block 31 is hollow so that the arch frame 37 can rotate along the inside of the arch block 31. A pair of mirror-image arched platforms 38 are fixedly connected to the inside of the arch frame 37. A pair of mirror-image movable columns 39 are fixedly connected to the inside between the arch pad 32 and the arch block 31. The movable columns 39 include an outer tube, an inner rod and a spiral beryllium copper wire D. One side of the outer tube is clamped to the inner rod. The outer sides of the outer tube and the inner rod are clamped with the beryllium copper wire D. The two sides of the beryllium copper wire D are respectively fixed to one side of the outer tube and the inner rod. The arch pad 32 is assembled inside the arch block 31 through a pair of movable columns 39. The side of the arch pad 32 close to the movable column 39 is fixedly connected to the arch seat 310. The two sides of the arch seat 310 are skewed, so that when the arch frame 37 rotates in the arch block 31, the arch platform 38 can be pulled to move together, so that the arch platform 38 can press the arch seat 310 along the skewed wall of the arch seat 310 to move, and the arch seat 310 can pull the arch pad 32 to stick to the surface of the restraint part, so as to achieve the restraint part. The arched seat 310 is located inside the arched frame 37. The outer surface of the arched frame 37 is fixedly connected to the adjusting platform 311. A groove is reserved on the outer surface of the arched block 31 for the adjusting platform 311 to constrain the movement. The side of the adjusting platform 311 farther from the arched frame 37 is fixedly connected to the toggle ring 312. The user can use the toggle ring 312 to pull the adjusting platform 311 to move along the groove on the outer surface of the arched block 31, and let the adjusting platform 311 pull the arched frame 37 to move along the inside of the arched block 31.

[0025] Reference Figure 4-10The folding unit includes a shell 313 fixedly connected to the outer wall of the protrusion A33, and a rotating disk A314 is screwed in the shell 313. One side of the rotating disk A314 is connected to the embedded column 35, so that when the rotating disk A314 rotates, the embedded column 35 can be pulled to rotate together. The inside of the shell 313 is screwed to the rotating disk B315. The outer circumferences of the rotating disk B315 and the rotating disk A314 are reserved with teeth and engage with each other through the teeth. The rotating disk B315 can pull the rotating disk A314 to rotate. The inside of the shell 313 is fixedly connected to a stop plate 316. The inside of the shell 313 is movably provided with a linkage bar 317. A plurality of teeth are reserved on one side of the linkage bar 317. The linkage bar 317 is connected to the rotating disk B31 The linkage bar 317 and the rotating disk B 315 cooperate with each other through the teeth, so that when the linkage bar 317 changes, the rotating disk B 315 can be pulled to rotate. The radius of the rotating disk A 314 is smaller than the radius of the rotating disk B 315, so as to prevent the linkage bar 317 and the rotating disk A 314 from touching each other. One side of the linkage bar 317 is fixedly connected to the linkage piece 318, and the linkage piece 318 can be moved and extended into the inside of the arch block 31. The inside of the arch frame 37 is fixedly connected to the arch piece 319. One side of the arch piece 319 is in contact with one side of the linkage piece 318, and the contacting walls of the arch piece 319 and the linkage piece 318 are both arched structures. When the arch frame 37 pulls the arch piece 319 to change, it can press the linkage piece 318 to change. When the linkage piece 318 moves, the linkage bar 317 can be pressed to change, thereby allowing the splicing column 35 to rotate. A spiral beryllium copper wire A320 is fixed between the linkage piece 318 and the stop piece 316. When the arch piece 319 is pulled back, the linkage piece 318 can be returned to its original position through the deformation of the beryllium copper wire A320. The side of the linkage piece 318 close to the beryllium copper wire A320 is fixed to the guide post 332. The guide post 332 can move through the stop piece 316. The linkage piece 318 can pull the guide post 332 to change along the inside of the stop piece 316, thereby enhancing the stability of the linkage piece 318. The side of the splicing column 35 farther from the rotating disk A314 is fixed to the constraint piece 321, and a space is reserved on the splicing table 36 for the constraint piece 321 to move. The through-hole passed through the plate 321 allows the through-holes on the constraint plate 321 and the embedding platform 36 to be staggered when the embedding column 35 rotates, completing the folding and locking of a pair of arch blocks 31. The rod on the other side of the rotating disk A314 extends outside the shell 313, and the side of the rod farther from the embedding column 35 is fixedly connected to the support platform 331, and the wall surface of the support platform 331 is in contact with the outer surface of the shell 313. The embedding column 35 is fixedly connected to the support tube 333 on the side close to the rotating disk A314, and the wall surface of the support tube 333 is in contact with the wall surface of the protrusion A33, allowing the support platform 331 and the support tube 333 to support the rotating disk A314 and the embedding column 35, thereby enhancing the stability of the embedding column 35 and the embedding platform 36 after connection.

[0026] Reference Figure 4-Figure 7The quick-release unit includes a pair of mirror-image arched columns 322 installed inside the arched block 31. The two sides of the arched columns 322 are fixedly connected to the stop platform 323. The stop platform 323 is fixedly connected to the inside of the arched block 31. An arched tube 324 is movably installed on the outer circumference of the arched column 322. The arched tube 324 is fixedly connected to the outside of the arched frame 37. When the arched frame 37 moves along the inside of the arched block 31, the arched tube 324 can be pulled to move along the outer circumference of the arched column 322. The outer circumference of the arched column 322 is connected to a spiral hoop. The beryllium copper wire B325 is fixedly connected between the arched tube 324 and the adjacent stop platform 323, so that when the arched tube 324 changes, the beryllium copper wire B325 is shortened. A wedge-shaped platform 326 is installed on the outer surface of the arched tube 324. The side of the wedge-shaped platform 326 farther from the beryllium copper wire B325 is tilted. A restraining opening for the wedge-shaped platform 326 to be restrained and engaged is reserved on the outer surface of the arched tube 324. When the arched tube 324 changes, the wedge-shaped platform 326 can be pressed from the restraining opening on the arched tube 324. The concave frame 327 is fixedly connected between the pair of wedge-shaped platforms 326. The concave frames 327 extend behind the arch block 31 and are movably connected to each other so that the user can pull the concave frames 327. Both sides of the concave frames 327 are fixedly connected to the movable plates 328. A channel is provided inside the arch block 31 to allow the concave frames 327 and the movable plates 328 to constrain the movement. When the wedge-shaped platforms 326 are moved, the movable plates 328 can be pulled along the channel of the arch block 31 through the concave frames 327. The spiral beryllium copper wire C329 is fixedly connected, so that the movable plate 328 can press the beryllium copper wire C329 when it moves. When the edge of the arch tube 324 and the outer surface of the wedge-shaped platform 326 are aligned, the deformation of the beryllium copper wire C329 allows the wedge-shaped platform 326 to press on the outer surface of the arch tube 324, completing the stop of the arch frame 37. When the concave frame 327 is pulled to change, the constraint on the arch tube 324 can be released, and the deformation of the beryllium copper wire B325 allows the arch tube 324 to return to its original position.

[0027] The specific implementation method is as follows: when in use, when restraining a patient, first place the patient on the bed 1, rotate the handle 25, the handle 25 pulls the screw 22 to rotate, the screw 22 makes the T-shaped slider 23 slide in the T-shaped slot 21, and then adjust the orientation of the limb restraint component 3 to ensure that the limb restraint component 3 can restrain the corresponding limb, place the restraint part between a pair of arch blocks 31, let the embedding columns 35 on a pair of protrusions A33 respectively embed into the embedding platforms 36 on a pair of protrusions B34, completing the first locking of the pair of arch blocks 31, then the user pulls the dial ring 312 on the outside of one of the arch blocks 31, and let the dial ring 312 pull the changing platform 311 to change along the groove outside the arch block 31, and the changing platform 311 pulls the arch block 31. The frame 37 moves along the inside of the arch block 31. This arch frame 37 can compress another arch frame 37 to rotate along the inside of the other arch block 31. The arch frame 37 pulls the arch tube 324 to move along the outer surface of the arch column 322. The restraining opening on the arch tube 324 compresses the tilted wall of the wedge-shaped platform 326 to change, so that the wedge-shaped platform 326 compresses the concave frame 327 to change. The concave frame 327 pulls the changing piece 328 to move along the channel of the arch block 31, compressing the beryllium copper wire C329, so that the wedge-shaped platform 326 is pressed on the surface of the arch tube 324, and the arch tube 324 compresses the beryllium copper wire B325. In addition, the arch frame 37 pulls the arch piece 319 to move together, so that the arch piece 319 compresses the linkage piece 318 to change. The linkage piece 318 is pressed by the arch frame 37. The linkage bar 317 is pulled along the inside of the shell 313 to move, so that the linkage bar 317 pulls the rotating disk B315 to rotate, and the rotating disk B315 pulls the rotating disk A314 to rotate, so that the rotating disk A314 pulls the splicing column 35 to rotate along the through-hole of the splicing platform 36, and the restraining piece 321 on the splicing column 35 can be staggered with the through-hole, so that the restraining piece 321 is pressed on the outer surface of the splicing platform 36, completing the locking of the pair of arch blocks 31, and then the arch frame 37 pulls the arch platform 38 to fit the skewed wall of the arch seat 310, and with the change of the arch frame 37, the arch platform 38 presses the arch seat 310 to change, and the arch seat 310 pulls the arch pad 32 to change together, so that the pair of arch pads 32 move together toward the surface of the restraint part, achieving the purpose of restraining the patient. The edge of the arched tube 324 and the outer surface of the wedge-shaped platform 326 are then aligned, and the deformation of the beryllium copper wire C329 allows the variable piece 328 to pull the wedge-shaped platform 326 along the edge of the arched tube 324 through the concave frame 327, and assists the beryllium copper wire B325 to press the arched tube 324, so that the wedge-shaped platform 326 can be pressed tightly against the edge of the arched tube 324, completing the restraint and support of the arched tube 324, and the arched platform 38 can lock the restraint part. During this period, the user only needs to use one hand to toggle one of the toggle rings 312 to complete the locking of the restraint part, thereby enhancing the convenience of use and ensuring that the restraint part of the patient can be quickly locked and restrained. Then, the restraint belt 5 is used to restrain the patient's body to ensure that the patient is fully restrained.Greatly improve the practicality of the device.
