Description

Technical Field

[0001] This invention belongs to the field of medical device technology, specifically relating to a restraint device for postoperative delirium patients. Background Technology

[0002] Postoperative delirium is a common complication in elderly patients after surgery, characterized by disturbances in consciousness, attention deficit, and cognitive impairment. Its pathogenesis involves multiple contributing factors, including anesthetic drugs, surgical stress, and inadequate pain management. Advanced age, preoperative cognitive impairment, and decreased physiological function significantly increase the risk. Clinical intervention emphasizes multidisciplinary collaboration, using medication adjustments, environmental optimization, and psychological support to improve symptoms. Preventive measures include preoperative high-risk screening and optimized intraoperative management. Patients with postoperative delirium may exhibit abnormal emotions and behaviors, such as restlessness, irritability, and aggression; therefore, restraint devices are necessary to control postoperative delirium.

[0003] Existing technology CN222444502U discloses a neurological intensive care restraint device, which includes a base, a mounting frame, and a hanger. The base has casters at its four bottom corners and uprights at its four top corners, with a bed frame on top of each upright. The mounting frame is located on both sides of the bed frame, with a sliding rod between the mounting frames. A slider is mounted on the sliding rod, with a fixing screw on one side of each slider. A support plate is located on top of the slider, and a fixing strap is located on top of the support plate. One end of each fixing strap has a locking sleeve and a locking pin.

[0038] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0039] Reference Figure 1 This invention provides a restraint device for postoperative delirium patients, comprising a bed 1, four sets of adjustment components 2 mirror-mounted on the bed 1, limb restraint components 3 mounted on the upper end of the adjustment components 2, a headrest 4 mounted in the center of one side of the bed 1, and two restraint straps 5 mounted in the center of the upper end of the bed 1, with the other ends of the two restraint straps 5 connected by a back strap buckle.

[0040] By installing the limb restraint component 3 and the restraint strap 5, the patient's limbs and torso can be restrained, ensuring that the patient can be adequately restrained, which greatly improves the practicality of the device.

[0041] Reference Figure 2 The adjustment component 2 includes a T-shaped slide groove 21 pre-reserved on the bed frame 1. A lead screw 22 is screwed into the T-shaped slide groove 21. A T-shaped slider 23 is screwed onto the lead screw 22. The T-shaped slider 23 is movably installed in the T-shaped slide groove 21. A support block 24 is fixedly connected to the upper end of the T-shaped slider 23. The support block 24 is connected to the limb restraint component 3. One side of the lead screw 22 extends out of the bed frame 1 and is fixedly connected to the handle 25.

[0042] When restraining a patient, first place the patient on the bed 1, rotate the handle 25, the handle 25 pulls the lead screw 22 to rotate, the lead screw 22 causes the T-shaped slider 23 to slide in the T-shaped groove 21, and then adjust the position of the limb restraint component 3 to ensure that the limb restraint component 3 can restrain the corresponding limb, reducing the limitations of the device's use.

[0043] Reference Figures 3-10 The limb restraint component 3 includes a pair of mirror-shaped arched blocks 31, each containing an arched pad 32. The patient's hands or legs are restrained via these arched pads 32. Several rubber strips are fixed to the side of the arched pad 32 furthest from the arched blocks 31, parallel to the arched blocks 31. These rubber strips enhance the resistance between the arched pad 32 and the restrained area, thus increasing the firmness of the restraint. 1. Each side is fixedly connected to a protrusion A33 and a protrusion B34. A fitting post 35 is installed on the protrusion A33, and a fitting platform 36 is fixedly connected to the protrusion B34 to constrain the fitting of the fitting post 35. The fitting posts 35 on a pair of protrusions A33 are each fitted into the fitting platforms 36 on a pair of protrusions B34, completing the initial fastening of a pair of arched blocks 31; it also includes: an adjustment unit, used to adjust a pair of arched pads 32 together, the adjustment unit is assembled inside the arched blocks 31.

[0044] The control unit includes an arched frame 37 screwed inside the arched block 31. The circumference of the arched block 31 is smaller than the circumference of the arched frame 37. When a pair of arched blocks 31 are brought close together, the two sides of the pair of arched frames 37 can be pressed together. When the user rotates one of the arched frames 37, the other arched frame 37 can be pressed against the inside of the arched block 31 and moved. Magnets 330 are fixed to both sides of the arched frame 37 so that the two sides of the pair of arched frames 37 can attract each other. The inside of the arched block 31 is hollow, so that the arched frame 37 can rotate along the inside of the arched block 31. A pair of mirror-image arched platforms 38 are fixed inside the arched frame 37. A pair of mirror-image movable columns 39 are fixed between the arched pad 32 and the inside of the arched block 31. The movable column 39 includes an outer cylinder, an inner rod, and a spiral beryllium copper wire D. One side of the outer cylinder is engaged with the inner rod, and the outer sides of the outer cylinder and the inner rod are clamped with the beryllium copper wire D. Both sides of the beryllium copper wire D are fixed to one side of the outer cylinder and the inner rod, respectively. An arched pad 32 is assembled inside an arched block 31 via a pair of movable columns 39. The side of the arched pad 32 closest to the movable columns 39 is fixed to an arched seat 310. The arched seat 310 is tilted on both sides. When the arched frame 37 rotates within the arched block 31, it can pull the arched platform 38 to move together. The arched platform 38 presses against the tilted wall of the arched seat 310, causing it to move. This allows the arched seat 310 to pull the arched pad 32 into contact with the surface of the restrained part, achieving restraint on the restrained part. The arched seat 310 is located inside the arched frame 37. The movable platform 311 is fixedly connected to the outer surface of the arched frame 37. The outer surface of the arched block 31 has grooves reserved to constrain the movement of the movable platform 311. The side of the movable platform 311 that is farther away from the arched frame 37 is fixedly connected to the actuating ring 312. The user can pull the movable platform 311 along the grooves on the outer surface of the arched block 31 through the actuating ring 312, so that the movable platform 311 can pull the arched frame 37 along the inside of the arched block 31.

[0045] Reference Figures 4-10The retractable unit includes a housing 313 fixed to the outer wall of the protrusion A33. A rotating disk A314 is screwed into the housing 313. One side of the rotating disk A314 is connected to a locking post 35, allowing the locking post 35 to rotate along with the rotating disk A314. A rotating disk B315 is screwed into the inside of the housing 313. Both the rotating disk B315 and the rotating disk A314 have pre-drilled teeth on their outer peripheral surfaces, which mesh with each other. The rotating disk B315 can pull the rotating disk A314 to rotate. A stop piece 316 is fixed inside the housing 313. A linkage bar 317 is movably installed inside the housing 313. One side of the linkage bar 317 has several pre-drilled teeth. The linkage bar 317 and the rotating disk B314 are connected to each other. 5. Through interlocking teeth, the linkage bar 317 and the rotating disk B315 cooperate to rotate, so that when the linkage bar 317 moves, it can pull the rotating disk B315 to rotate. The radius of the rotating disk A314 is smaller than the radius of the rotating disk B315 to avoid the linkage bar 317 and the rotating disk A314 from touching. One side of the linkage bar 317 is fixedly connected to the linkage piece 318, which can move and extend into the inside of the arched block 31. The inside of the arched frame 37 is fixedly connected to the arched piece 319, one side of the arched piece 319 is in contact with one side of the linkage piece 318, and the walls of the arched piece 319 and the linkage piece 318 that are in contact are both arched structures, so that when the arched frame 37 pulls the arched piece 319 to move, it can compress the linkage piece 318 to change. When the linkage plate 318 moves, it can compress the linkage bar 317 to move, thereby causing the interlocking post 35 to rotate. A spiral beryllium copper wire A320 is fixed between the linkage plate 318 and the stop plate 316. When the arched plate 319 is pulled back, the deformation of the beryllium copper wire A320 can cause the linkage plate 318 to return to its original position. The side of the linkage plate 318 closest to the beryllium copper wire A320 is fixed to the guide post 332. The guide post 332 can move through the stop plate 316. The linkage plate 318 can pull the guide post 332 to move along the inside of the stop plate 316, enhancing the stability of the movement of the linkage plate 318. The side of the interlocking post 35 furthest from the rotating disk A314 is fixed to the constraint plate 321. The interlocking platform 36 is reserved for the constraint plate 321. The through-hole of plate 321 allows the through-holes on the restraint plate 321 and the interlocking platform 36 to be misaligned when the interlocking post 35 rotates, thus completing the closing and locking of a pair of arched blocks 31. The rod on the other side of the rotating disk A314 extends beyond the outer shell 313, and the side of the rod farther from the interlocking post 35 is fixed to the support platform 331. The wall of the support platform 331 is in contact with the outer surface of the outer shell 313. The side of the interlocking post 35 closest to the rotating disk A314 is fixed to the support tube 333. The wall of the support tube 333 is in contact with the wall of the protrusion A33, allowing the support platform 331 and the support tube 333 to provide support for the rotating disk A314 and the interlocking post 35, thereby enhancing the stability of the interlocking post 35 and the interlocking platform 36 after connection.

[0046] Reference Figures 4-7The quick-release unit includes a pair of arched columns 322 mirror-mounted inside the arched block 31. The arched columns 322 are fixed to stop platforms 323 on both sides, which are fixed inside the arched block 31. An arched tube 324 is movably mounted on the outer circumferential surface of the arched columns 322. The arched tube 324 is fixed to the outside of the arched frame 37, allowing the arched frame 37 to move along the inside of the arched block 31, thereby pulling the arched tube 324 along the outer circumferential surface of the arched columns 322. A spiral is wound around the outer circumferential surface of the arched columns 322. A beryllium copper wire B325 is fixed between the arched tube 324 and the adjacent stop platform 323. When the arched tube 324 moves, the beryllium copper wire B325 shortens. A wedge-shaped platform 326 is installed on the outer surface of the arched tube 324. The side of the wedge-shaped platform 326 furthest from the beryllium copper wire B325 is skewed. A constraint opening is provided on the outer surface of the arched tube 324 to allow the wedge-shaped platform 326 to be restrained and fitted, so that when the arched tube 324 moves, it can compress the wedge-shaped platform 326 through the constraint opening on the arched tube 324. The wedge-shaped platforms 326 are fixedly connected to a concave frame 327. The concave frame 327 extends behind the arched block 31 and is movably connected to each other, allowing the user to pull the concave frame 327. Movable pieces 328 are fixedly connected to both sides of the concave frame 327. A channel is installed inside the arched block 31 to constrain the movement of the concave frame 327 and the movable pieces 328. When the wedge-shaped platforms 326 move, the movable pieces 328 can be pulled along the channel of the arched block 31 via the concave frame 327. The movable pieces 328 and the channel... A spiral beryllium copper wire C329 is fixedly connected, allowing the movable piece 328 to press the beryllium copper wire C329 when it moves. When the edge of the arched tube 324 is aligned with the outer surface of the wedge-shaped platform 326, the deformation of the beryllium copper wire C329 causes the wedge-shaped platform 326 to press against the outer surface of the arched tube 324, thus stopping the arched frame 37. When the concave frame 327 is pulled to move, the constraint on the arched tube 324 is released, and the deformation of the beryllium copper wire B325 allows the arched tube 324 to return to its original position by itself.

[0047] The specific implementation method is as follows: When using the device to restrain a patient, first place the patient on the bed 1, rotate the handle 25, the handle 25 pulls the lead screw 22 to rotate, the lead screw 22 causes the T-shaped slider 23 to slide in the T-shaped groove 21, then adjust the position 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 arched blocks 31, so that the interlocking posts 35 on a pair of protrusions A33 are respectively interlocked into the interlocking platforms 36 on a pair of protrusions B34, completing the initial locking of the pair of arched blocks 31. Then, the user pulls the actuating ring 312 on the outside of one of the arched blocks 31, so that the actuating ring 312 pulls the moving platform 311 along the groove on the outside of the arched block 31, and the moving platform 311 pulls the arched block 31. The frame 37 moves along the inside of the arched block 31. This arched frame 37 can press another arched frame 37 to rotate together along the inside of another arched block 31. The arched frame 37 pulls the arched tube 324 to move along the outer surface of the arched column 322. The constraint port on the arched tube 324 presses the inclined wall of the wedge-shaped platform 326 to move, so that the wedge-shaped platform 326 presses the concave frame 327 to move. The concave frame 327 pulls the moving piece 328 to move along the channel of the arched block 31, pressing the beryllium copper wire C329, so that the wedge-shaped platform 326 presses against the surface of the arched tube 324, and the arched tube 324 presses the beryllium copper wire B325. The arched frame 37 pulls the arched piece 319 to move together, so that the arched piece 319 presses the linkage piece 318 to move. 18. The traction linkage bar 317 moves along the inside of the outer shell 313, causing the linkage bar 317 to pull the rotating disk B315 to rotate. The rotating disk B315 pulls the rotating disk A314 to rotate, causing the rotating disk A314 to pull the interlocking post 35 to rotate along the through-hole of the interlocking platform 36. The constraint piece 321 on the interlocking post 35 can then be misaligned with the through-hole, allowing the constraint piece 321 to press against the outer surface of the interlocking platform 36, thus locking the pair of arched blocks 31. Then, the arched frame 37 pulls the arched platform 38 and the arched seat 310 to fit together. With the movement of the arched frame 37, the arched platform 38 presses against the arched seat 310 to move. The arched seat 310 pulls the arched pad 32 to move together, causing the pair of arched pads 32 to move towards the surface of the restrained area, achieving the effect of restraining the patient. The arched tube 324 is then aligned with the outer surface of the wedge-shaped platform 326. Through the deformation of the beryllium copper wire C329, the moving piece 328, via the concave frame 327, pulls the wedge-shaped platform 326 along the edge of the arched tube 324, assisting the beryllium copper wire B325 in pressing against the arched tube 324. This allows the wedge-shaped platform 326 to press firmly against the edge of the arched tube 324, completing the restraint and support of the arched tube 324. The arched platform 38 can then lock the restrained area. During this process, the user can lock the restrained area by simply moving one of the lever rings 312 with one hand, enhancing ease of use and ensuring rapid locking and restraint of the patient's restrained area. Then, the restraint strap 5 is used to restrain the patient's body, ensuring adequate restraint.This greatly improves the practicality of the device.
