Summary of the Invention

[0004] The present invention provides a severe neurology restraint device, aiming to solve the problem that when the existing severe neurology restraint device is in use, the patient is bound and fixed by three groups of fixing straps, but the head, hands and feet of the patient can still move, and there is still a certain degree of danger.

[0005] An embodiment of the present invention provides a severe neurology restraint device, including a movable bottom plate, two pairs of support columns are fixedly connected to the upper end of the movable bottom plate, a bed body is fixedly connected to the upper end of the support columns, a pair of cross bars are symmetrically arranged on the bed body, longitudinal adjustment components are arranged at both ends of the cross bars, four groups of transverse adjustment components are arranged on the cross bars, a chest restraint component, a hand restraint component, a leg restraint component and a foot restraint component are respectively arranged on the four groups of transverse adjustment components, and a head restraint component is arranged on the bed body and on the side where the chest restraint component is far from the hand restraint component.

[0006] By adopting the above technical solution, through the chest restraint component, hand restraint component, leg restraint component, foot restraint component and head restraint component, the device can restrain the patient at multiple positions, greatly improving the safety during use. And through the setting of the longitudinal adjustment component and the transverse adjustment component, the device can meet different patients, greatly reducing the limitations of the device in use.

[0007] Further, the longitudinal adjustment component includes two groups of slideways opened at both ends of the bed body and several supports one fixed on one side of the bed body. A lead screw is rotatably connected in each group of slideways. The thread directions at both ends of the lead screw are opposite. A slider is threadedly connected to the lead screw. The side walls of two laterally opposite sliders are respectively connected to both ends of the corresponding cross bar. One end of the lead screw extends out of the bed body and is fixed with a bevel gear one. A rotating shaft is rotatably connected to the support one. Bevel gears two are fixed at both ends of the rotating shaft. The bevel gear one is meshed and connected with the bevel gear two. One end of the rotating shaft is fixed with a handle.

[0008] By adopting the above technical solution, when adjusting the longitudinal distance, shake the handle by hand. The handle drives the rotating shaft to rotate. The rotating shaft drives the lead screw to rotate through the bevel gear two and the bevel gear one. The lead screw drives the slider to slide in the slideway, thereby adjusting the longitudinal distance, facilitating the hand restraint component and the foot restraint component to restrain the arm and the foot.

[0009] Further, the transverse adjustment component includes a sliding sleeve slidably connected to the cross bar. A positioning pin is movably connected to the sliding sleeve. One end of the positioning pin penetrates through the sliding sleeve and is engaged in a positioning hole on the cross bar. The other end of the positioning pin is fixed with a pulling block. A first spring is sleeved outside the positioning pin. Both ends of the first spring are respectively on the positioning pin and the side wall of the sliding sleeve.

[0010] By adopting the above technical solution, when adjusting the positions of the chest restraint component, hand restraint component, leg restraint component and foot restraint component, pull the pulling block outwards, so that the positioning pin disengages from the positioning hole. Slide the sliding sleeve to the required position and release the pulling block. Under the cooperation of the first spring, the positioning pin is engaged in the corresponding positioning hole, thereby ensuring the use of the chest restraint component, hand restraint component, leg restraint component and foot restraint component.

[0011] Further, the structures of the chest restraint component and the leg restraint component are the same. The chest restraint component includes two restraint belts one fixed on two longitudinally opposite sliding sleeves. The other ends of the two restraint belts one are detachably connected through a buckle one.

[0012] By adopting the above technical solution, when restraining the chest or the leg, connect the movable ends of the two restraint belts one with the buckle one, and restrain the chest or the leg of the patient through the two restraint belts one.

[0013] Furthermore, the hand restraint assembly has the same structure as the foot restraint assembly. The hand restraint assembly includes a pair of second restraint straps fixedly connected to a sliding sleeve, and the other ends of the two second restraint straps are detachably connected via a second buckle.

[0014] By adopting the above technical solution, when restraining the arm or foot, the movable ends of the two second restraint straps are connected by the second buckle, and the patient's arm or foot is restrained by the two second restraint straps.

[0015] Furthermore, the head restraint assembly includes a head restraint structure. The head restraint structure includes two movable slots and two insertion slots formed in the bed body. The two movable slots are inside the two insertion slots. One side of the movable slot is fixedly connected to a second spring, and the other end of the second spring is fixedly connected to a side splint. The bumps on both side walls of the side splint are fitted into the grooves on both side walls of the movable slot, and the side splint is slidably connected to the movable slot. An arc-shaped cushion plate is arranged between the two side splints, and the arc-shaped cushion plate is fixedly connected to the bed body. An upper arc-shaped splint is arranged above the arc-shaped cushion plate. The two ends of the upper arc-shaped splint are fixedly connected with insertion plates, and the insertion plates are inserted into the corresponding insertion slots. The lower arc-shaped surface of the upper arc-shaped splint contacts the upper ends of the side splints, and the upper ends of the side splints are arc-shaped.

[0016] By adopting the above technical solution, when restraining the patient's head, the patient's head is first placed on the arc-shaped cushion plate, and the insertion plates are inserted into the corresponding insertion slots. When inserting the insertion plates, the upper arc-shaped splint presses the side splints, and under the action of the arc-shaped surface, the two side splints move towards both sides of the patient's head at the same time, thereby realizing the restraint of the patient's head.

[0017] Furthermore, soft pads are fixedly connected to the inner sides of the side splints, the upper wall surface of the arc-shaped cushion plate, and the lower arc-shaped surface of the upper arc-shaped splint.

[0018] By adopting the above technical solution, it is avoided to cause damage to the patient's head during the restraint process of the patient, and at the same time, the comfort during use is ensured.

[0019] Further, the head restraint assembly further includes a positioning structure. The positioning structure includes a plurality of wedge-shaped blocks fixedly connected to the outer wall surface of the insertion plate and an installation groove opened on the lower wall surface of the bed body. The upper wall surface of the wedge-shaped block is a horizontal plane, and the lower wall surface of the wedge-shaped block is an inclined plane slanting upward. An activity plate is slidably arranged in the installation groove. Protrusions on both side walls of the activity plate are fitted into grooves on both side walls of the installation groove. One wall surface of the activity plate is fixedly connected to the bottom wall of the installation groove through a third spring. A positioning block is fixedly connected to the other wall surface of the activity plate. The other end of the positioning block passes through the installation groove and extends between two wedge-shaped blocks in the insertion slot. The upper end of the other end of the positioning block is an inclined plane slanting downward, and the lower end of the other end of the positioning block is a horizontal plane. The horizontal plane of the positioning block is in contact with the horizontal plane of the corresponding wedge-shaped block, and the inclined plane of the positioning block is in contact with the inclined plane of the corresponding wedge-shaped block.

[0020] By adopting the above technical solution, during the process of inserting the insertion plate downward into the insertion slot, the inclined plane of the wedge-shaped block contacts the inclined plane of the positioning block and pushes the positioning block to both sides. The third spring contracts. When the insertion plate moves to the required position, the positioning block is placed between the two wedge-shaped blocks. The third spring makes the positioning block firmly inserted between the two wedge-shaped blocks to position the insertion plate, and further realizes the positioning of the side splint and the upper arc-shaped splint, ensuring the stable positioning of the patient's head.

[0021] Further, the head restraint assembly further includes a disassembly structure. The disassembly structure includes a second support fixedly connected to the lower end of the activity plate and a rotating shaft rotatably connected to the lower wall surface of the bed body. A rotating disk is fixedly connected to the lower end of the rotating shaft. A torsion spring is sleeved on the outer surface of the rotating shaft. Two ends of the torsion spring are respectively fixedly connected to the lower wall surface of the bed body and the upper wall surface of the rotating disk. Two pin shafts are fixedly connected to the side of the upper wall surface of the rotating disk. One end of a linkage rod is rotatably connected to each pin shaft. The other ends of the two linkage rods are respectively rotatably connected to the two second supports.

[0022] By adopting the above technical solution, when releasing the head restraint, twist the rotating disk to drive the pin shaft to rotate. The rotating pin shaft drives the two linkage rods to extend to both sides, thereby pushing the activity plate to move outward. The activity plate then drives the positioning block to move toward the inside of the installation groove. The positioning block moves away from the wedge-shaped block to release the positioning of the insertion plate. Pull up the upper arc-shaped splint, and the insertion plate can be removed from the insertion slot. Then loosen the rotating disk, and under the action of the torsion spring, the rotating disk resets.

[0023] The beneficial effects of the present invention are as follows: Through the chest restraint assembly, hand restraint assembly, leg restraint assembly, foot restraint assembly and head restraint assembly of the present invention, the device can restrain the patient at multiple positions, greatly improving the safety during use. And through the setting of the longitudinal adjustment assembly and the transverse adjustment assembly, the device can meet different patients, greatly reducing the limitations of the device in use.

[0029] When adjusting the longitudinal distance, turn the handle 58 by hand. The handle 58 drives the rotating shaft 56 to rotate. The rotating shaft 56 drives the lead screw 52 to rotate through the bevel gear 57 and the bevel gear 54. The lead screw 52 drives the slider 53 to slide in the slideway 51, thereby adjusting the longitudinal distance, facilitating the hand restraint component 9 and the foot restraint component 10 to restrain the arm and the foot.

[0030] Refer to Figure 1 And Figure 2 , the transverse adjustment component 6 includes a sliding sleeve 61 slidably connected to the cross bar 4. A positioning pin 62 is movably connected to the sliding sleeve 61. One end of the positioning pin 62 penetrates through the sliding sleeve 61 and is engaged in a positioning hole on the cross bar 4. The other end of the positioning pin 62 is fixedly connected to a pulling block 63. A first spring 64 is sleeved outside the positioning pin 62. Both ends of the first spring 64 are respectively on the positioning pin 62 and the side wall of the sliding sleeve 61.

[0031] When adjusting the positions of the chest restraint assembly 7, the hand restraint assembly 9, the leg restraint assembly 8, and the foot restraint assembly 10, pull the pull block 63 outward so that the positioning pin 62 disengages from the positioning hole, slide the sliding sleeve 61 to the desired position, release the pull block 63, and with the cooperation of the first spring 64, the positioning pin 62 snaps into the corresponding positioning hole to ensure the use of the chest restraint assembly 7, the hand restraint assembly 9, the leg restraint assembly 8, and the foot restraint assembly 10.

[0032] Embodiment 2 The difference from Embodiment 1 is that, referring to Figure 1 , the chest restraint assembly 7, the hand restraint assembly 9, the leg restraint assembly 8, and the foot restraint assembly 10 are respectively arranged on the four groups of lateral adjustment assemblies 6. The structures of the chest restraint assembly 7 and the leg restraint assembly 8 are the same. Here, the chest restraint assembly 7 is taken as an example for description. The chest restraint assembly 7 includes two first restraint bands 71 fixedly connected to two sliding sleeves 61 opposite to each other longitudinally. The other ends of the two first restraint bands 71 are detachably connected via a first buckle 72.

[0033] When restraining the chest or legs, use the first buckle 72 to connect the movable ends of the two first restraint bands 71, and restrain the patient's chest or legs through the two first restraint bands 71.

[0034] The structures of the hand restraint assembly 9 and the foot restraint assembly 10 are the same. Here, the hand restraint assembly 9 is taken as an example for description. The hand restraint assembly 9 includes a pair of second restraint bands 91 fixedly connected to a sliding sleeve 61. The other ends of the two second restraint bands 91 are detachably connected via a second buckle 92.

[0035] When restraining the arm or foot, use the second buckle 92 to connect the movable ends of the two second restraint bands 91, and restrain the patient's arm or foot through the two second restraint bands 91.

[0036] Embodiment 3 The difference from Embodiment 2 is that, referring to Figure 1 , Figures 3 - 6, on the bed body 3 and on the side of the chest restraint assembly 7 away from the hand restraint assembly 9, a head restraint assembly 11 is provided. The head restraint assembly 11 includes a head restraint structure. The head restraint structure includes two movable slots 111 and two insertion slots 112 opened on the bed body 3. The two movable slots 111 are inside the two insertion slots 112. One side of the movable slot 111 is fixedly connected to a second spring 113. The other end of the second spring 113 is fixedly connected to a side clamping plate 114. The bumps on the two side walls of the side clamping plate 114 are fitted into the grooves on the two side walls of the movable slot 111. The side clamping plate 114 is slidably connected to the movable slot 111. An arc-shaped cushion plate 115 is provided between the two side clamping plates 114. The arc-shaped cushion plate 115 is fixedly connected to the bed body 3. Above the arc-shaped cushion plate 115, an upper arc-shaped clamping plate 116 is provided. The two ends of the upper arc-shaped clamping plate 116 are fixedly connected with insertion plates 117. The insertion plates 117 are inserted into the corresponding insertion slots 112. The lower arc-shaped surface of the upper arc-shaped clamping plate 116 contacts the upper ends of the side clamping plates 114. The upper ends of the side clamping plates 114 are arc-shaped.

[0037] When restraining the patient's head, the patient's head is first placed on the arc-shaped cushion plate 115, and the insertion plates 117 are inserted into the corresponding insertion slots 112. When inserting the insertion plates 117, the upper arc-shaped clamping plate 116 squeezes the side clamping plates 114. Under the action of the arc-shaped surface, the two side clamping plates 114 move towards both sides of the patient's head at the same time, so as to realize the restraint of the patient's head.

[0038] Soft pads are fixedly connected to the inner sides of the side clamping plates 114, the upper wall surface of the arc-shaped cushion plate 115 and the lower arc-shaped surface of the upper arc-shaped clamping plate 116, so as to avoid damaging the patient's head during the restraint process of the patient, and at the same time ensure the comfort during use.

[0039] Refer to Figure 6 , the head restraint assembly 11 further includes a positioning structure. The positioning structure includes a plurality of wedge-shaped blocks 118 fixedly connected to the outer wall surface of the insertion plate 117 and an installation groove 119 opened on the lower wall surface of the bed body 3. The upper wall surface of the wedge-shaped block 118 is a horizontal plane, and the lower wall surface of the wedge-shaped block 118 is an inclined plane slanting upwards. A movable plate 1110 is slidably arranged in the installation groove 119. The bumps on the two side walls of the movable plate 1110 are fitted into the grooves on the two side walls of the installation groove 119. One wall surface of the movable plate 1110 is fixedly connected to the bottom wall of the installation groove 119 through a third spring 1111. A positioning block 1112 is fixedly connected to the other wall surface of the movable plate 1110. The other end of the positioning block 1112 passes through the installation groove 119 and extends between the two wedge-shaped blocks 118 in the insertion slot 112. The upper end of the other end of the positioning block 1112 is an inclined plane slanting downwards, and the lower end of the other end of the positioning block 1112 is a horizontal plane. The horizontal plane of the positioning block 1112 is in contact with the horizontal plane of the corresponding wedge-shaped block 118, and the inclined plane of the positioning block 1112 is in contact with the inclined plane of the corresponding wedge-shaped block 118.

[0040] During the process of inserting the plug board 117 downward into the slot 112, the inclined surface of the wedge block 118 contacts the inclined surface of the positioning block 1112 and pushes the positioning block 1112 to both sides. The third spring 1111 contracts. When the plug board 117 moves to the required position, the positioning block 1112 is placed between the two wedge blocks 118. The third spring 1111 makes the positioning block 1112 firmly inserted between the two wedge blocks 118 to position the plug board 117, thereby realizing the positioning of the side clamping plate 114 and the upper arc-shaped clamping plate 116, and ensuring the stable positioning of the patient's head.

[0041] Referring to Figures 3 - 5 , the head restraint assembly 11 further includes a disassembly structure. The disassembly structure includes a second support 1113 fixedly connected to the lower end of the movable plate 1110 and a rotating shaft 1114 rotatably connected to the lower wall surface of the bed body 3. The lower end of the rotating shaft 1114 is fixedly connected with a rotating disk 1116. A torsion spring 1115 is sleeved on the outer surface of the rotating shaft 1114. The two ends of the torsion spring 1115 are respectively fixedly connected with the lower wall surface of the bed body 3 and the upper wall surface of the rotating disk 1116. Two pin shafts 1117 are fixedly connected to the side of the upper wall surface of the rotating disk 1116. One end of a linkage rod 1118 is rotatably connected to each pin shaft 1117. The other ends of the two linkage rods 1118 are respectively rotatably connected to the two second supports 1113.

[0042] When releasing the head restraint, twist the rotating disk 1116 to drive the pin shaft 1117 to rotate. The rotating pin shaft 1117 drives the two linkage rods 1118 to extend to both sides, thereby pushing the movable plate 1110 to move outward. The movable plate 1110 then drives the positioning block 1112 to move toward the inside of the installation groove 119. The positioning block 1112 moves away from the wedge block 118 to release the positioning of the plug board 117. Pull up the upper arc-shaped clamping plate 116, and the plug board 117 can be removed from the slot 112. Then release the rotating disk 1116. Under the action of the torsion spring 1115, the rotating disk 1116 returns to its original position.

[0043] The implementation method is specifically as follows: When in use, adjust the device according to the patient's body type so that the device meets the patient's usage requirements. Adjust the longitudinal position by manually rotating the handle 58. The handle 58 drives the rotation of the rotating shaft 56. The rotating shaft 56 drives the rotation of the lead screw 52 through the second bevel gear 57 and the first bevel gear 54. The lead screw 52 drives the slider 53 to slide in the slideway 51, thereby adjusting the longitudinal distance. Then, adjust the lateral position. Pull the pull block 63 outwards so that the positioning pin 62 disengages from the positioning hole. Slide the sliding sleeve 61 to the desired position and release the pull block 63. Under the cooperation of the first spring 64, the positioning pin 62 engages with the corresponding positioning hole to ensure the use of the chest restraint assembly 7, the hand restraint assembly 9, the leg restraint assembly 8, and the foot restraint assembly 10. Then, use the hand restraint assembly 9 and the foot restraint assembly 10 to restrain the arm and the foot respectively. Connect the movable ends of the two second restraint straps 91 with the second buckle 92, and restrain the patient's arm or foot through the two second restraint straps 91. Then, use the chest restraint assembly 7 and the leg restraint assembly 8 to restrain the patient's chest and leg respectively. Connect the movable ends of the two first restraint straps 71 with the first buckle 72, and restrain the patient's chest or leg through the two first restraint straps 71. Finally, fix the head. First, place the patient's head on the arc-shaped backing plate 115, and insert the insertion plate 117 into the corresponding slot 112. When inserting the insertion plate 117, the upper arc-shaped clamping plate 116 presses the side clamping plates 114. Under the action of the arc surface, the two side clamping plates 114 move towards both sides of the patient's head simultaneously. When the insertion plate 117 is inserted downward into the slot 112, the inclined surface of the wedge block 118 contacts the inclined surface of the positioning block 1112 and pushes the positioning block 1112 towards both sides. The third spring 1111 contracts. When the insertion plate 117 reaches the desired position, the positioning block 1112 is placed between the two wedge blocks 118. The third spring 1111 makes the positioning block 1112 firmly inserted between the two wedge blocks 118 to position the insertion plate 117, thereby realizing the positioning of the side clamping plates 114 and the upper arc-shaped clamping plate 116 and ensuring the stable positioning of the patient's head. After use, when it is necessary to release the restraint on the patient, twist the rotating disk 1116 to drive the rotation of the pin shaft 1117. The rotating pin shaft 1117 drives the two linkage rods 1118 to extend towards both sides, thereby pushing the movable plate 1110 to move outwards. The movable plate 1110 then drives the positioning block 1112 to move towards the inside of the installation groove 119. The positioning block 1112 moves away from the wedge block 118 to release the positioning of the insertion plate 117. Pull up the upper arc-shaped clamping plate 116, and the insertion plate 117 moves out of the slot 112 to release the restraint on the head. Then, unfasten the first buckle 72 and the second buckle 92 in sequence to release the restraint on the patient.
