DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the 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.

[0032] See also Figure 1-5 The present invention provides a technical solution: a limb fixation device for clinical peritoneal dialysis in the Department of Nephrology, comprising a bed 5, and also comprising:

[0033] The supporting and fixing mechanism 1 comprises a fixing plate 101 and an extrusion push plate 102. The extrusion push plate 102 is slidably mounted on the fixing plate 101. A connecting frame 103 is fixedly connected to the fixing plate 101. A plug-in through hole 104 is provided in the connecting frame 103. A connecting rod 2 is plugged into the plug-in through hole 104. An L-shaped connecting piece 110 is connected to the bottom of the fixing plate 101.

[0034] The waist clamping mechanism 3 includes an arc plate 301 and a close-fitting airbag 302. The close-fitting airbag 302 is fixedly connected to the inner wall of the arc plate 301. A plurality of convex points 303 are fixedly connected to the close-fitting airbag 302. The waist clamping mechanism 3 is connected to one end of the connecting rod 2.

[0035] The tensioning mechanism 4 includes two tensioning plates 401 . A protrusion is provided on the tensioning plate 401 . A clamping groove 405 is provided on one side of the protrusion. The clamping groove 405 cooperates with the L-shaped connector 110 .

[0036] In this embodiment, when in use, the tensioning mechanism 4 needs to be passed under the hospital bed 5 to gradually reduce the distance between the two tensioning plates 401, and the clamping groove 405 cooperates with the fixing plate 101 to clamp the tensioning plate 401 and the L-shaped connecting piece 110 together. At this time, the length of the tensioning mechanism 4 is reduced, which will drive the two supporting and fixing mechanisms 1 to be clamped on both sides of the hospital bed 5, and then the supporting and fixing mechanisms 1 are fixed on the hospital bed 5, and the connecting rod 2 is inserted into the plug-in through hole 104. The connecting rod 2 is used to connect the supporting and fixing mechanisms 1 and the waist clamping mechanism 3, and the extrusion push plate 102 is slidably installed on the fixing plate 101, and the extrusion push plate 102 is used to resist one end of the connecting rod 2. The extrusion push plate 102 is moved to drive the connecting rod 2 to move, and the connecting rod 2 moves It will drive the waist clamping mechanism 3 to move, and then use the two waist clamping mechanisms 3 to squeeze and clamp the positions of the patient's waist on both sides, so as to fix and limit the patient's limbs. The close-fitting airbag 302 arranged in the arc plate 301 will be in direct contact with the patient, and a certain amount of air will be filled into the close-fitting airbag 302. At this time, the close-fitting airbag 302 will expand and gradually fill the gap between the arc plate 301 and the patient's waist, so that the waist clamping mechanism 3 can fit the waist of patients with different body shapes. At the same time, when the patient turns over to adjust his position, the waist clamping mechanism 3 will be squeezed to push the supporting and fixing mechanism 1 outward. Since the supporting and fixing mechanism 1 is connected by two tightening mechanisms 4, it can provide sufficient clamping force to avoid the problem of slipping and displacement of the supporting and fixing mechanism 1 after being subjected to force.

[0037] In order to avoid the interference between the tensioning mechanism 4 and the bed 5, the device is implemented by the following technical solutions: a T-shaped slide groove 108 is provided on the fixing plate 101, a T-shaped slider 106 is fixedly connected to the bottom of the extrusion push plate 102, the T-shaped slider 106 is slidably matched with the T-shaped slide groove 108, a first threaded through hole 107 is provided in the T-shaped slider 106, an adjusting screw rod 109 is rotatably installed in the T-shaped slide groove 108, and the adjusting screw rod 109 is rotatably connected with the first threaded through hole 107. 07 threaded match, a limit rod 111 is fixedly connected to the bottom of the fixed plate 101, a limit plug hole 115 is provided on the L-shaped connecting piece 110, the limit plug hole 115 is slidably matched with the limit rod 111, a threaded adjustment column 112 is rotatably installed on the bottom of the fixed plate 101, a knob 113 is fixedly connected to the threaded adjustment column 112, a first threaded sleeve 114 is embedded and installed on the L-shaped connecting piece 110, and the first threaded sleeve 114 is threadedly matched with the threaded adjustment column 112.

[0038] The extrusion push plate 102 is slidably mounted on the fixed plate 101 through the sliding cooperation of the T-shaped slide groove 108 and the T-shaped slider 106. At the same time, the adjusting screw rod 109 is threadedly cooperated with the first threaded through hole 107. The rotating adjusting screw rod 109 can drive the T-shaped slider 106 to move. The movement of the T-shaped slider 106 can drive the extrusion push plate 102 to move, thereby adjusting the position of the extrusion push plate 102. The fixed threaded shaft rod 105 is threadedly cooperated with the first threaded connection hole 202. The limiting rod 111 is slidably cooperated with the limiting plug hole 115, which can limit the L-shaped connector 110 It can only move up and down, and the knob 113 can be used to drive the threaded adjustment column 112 to rotate. The threaded adjustment column 112 is threadedly matched with the first threaded sleeve 114, and then the rotation of the threaded adjustment column 112 can drive the L-shaped connector 110 to move, and adjust the distance between the L-shaped connector 110 and the fixed plate 101. Since the thickness of different specifications of the hospital beds 5 is also different, adjusting the distance between the L-shaped connector 110 and the fixed plate 101 can avoid the tensioning mechanism 4 and the hospital bed 5 When the bed 5 is thick, the interference, the L-shaped connector 110 cannot be connected with the tensioning mechanism 4

[0039] Among them, in order to achieve the purpose of adjusting the position of the waist clamping mechanism 3 to clamp it on the patient's waist, the present device is implemented by the following technical solutions: the connecting rod 2 includes a plurality of connecting columns 201, one end of the connecting column 201 is fixedly connected with a threaded connector 203, and the other end of the connecting column 201 is provided with a first threaded connection hole 202, the connecting column 201 is threadedly matched with the first threaded connection hole 202, a fixed threaded shaft 105 is rotatably installed in the extrusion push plate 102 through a bearing, the fixed threaded shaft 105 is threadedly matched with the first threaded connection hole 202, a connecting boss 305 is fixedly connected to the outer wall of the arc plate 301, a valve core 304 is fixedly connected to the close-fitting airbag 302, a second threaded connection hole 306 is threadedly matched with the threaded connector 203 at the other end of the connecting boss 305.

[0040] The connecting rod 2 is composed of a plurality of connecting columns 201 connected end to end. The number of connecting columns 201 can be appropriately increased or decreased according to the patient's body shape and the width of the bed 5, and the length of the connecting rod 2 can be adjusted. After the connecting rod 2 is inserted into the plug-in through hole 104, the fixed threaded shaft 105 is rotated and screwed into the first threaded connecting hole 202, so that the extrusion push plate 102 can be connected to the connecting rod 2 together. By adjusting the position of the extrusion push plate 102, the connecting rod 2 can be fine-tuned so that the waist clamping mechanism 3 fits the patient's waist as closely as possible. The second threaded connecting hole 306 is threadedly matched with the threaded connector 203, so that the connecting rod 2 can be connected to the waist clamping mechanism 3 together. The multiple protrusions 303 arranged on the surface of the close-fitting airbag 302 leave a certain gap between the close-fitting airbag 302 and the patient's waist. In the process of the close-fitting airbag 302 fitting the patient's waist, the patient's skin can sweat, effectively increasing the patient's comfort.

[0041] Among them, in order to achieve the purpose of changing the overall length of the tensioning mechanism 4, the present device adopts the following technical solution: a connecting screw 402 is rotatably installed under one of the tensioning plates 401 through a bearing seat, and a rotating disk 404 is fixedly connected to one end of the connecting screw 402; a second threaded sleeve 403 is fixedly connected to the other tensioning plate 401, and the second threaded sleeve 403 is threadedly matched with the connecting screw 402.

[0042] The connecting screw 402 can be driven to rotate through the rotating disk 404, and the connecting screw 402 is threadedly matched with the second threaded sleeve block 403, so that the rotation of the connecting screw 402 can drive the tensioning plate 401 to move, adjust the distance between the two tensioning plates 401, and then change the overall length of the tensioning mechanism 4, so that the tensioning mechanism 4 can drive the supporting and fixing mechanism 1 to clamp on both sides of the bed 5.

[0043] The working principle and use process of the present invention are as follows: when in use, the tensioning mechanism 4 needs to be passed under the hospital bed 5, and the two sides of the two supporting and fixing mechanisms 1 need to be placed on both sides of the hospital bed 5, and the L-shaped connecting piece 110 needs to be aligned with the clamping groove 405, and the rotating disk 404 needs to be rotated to drive the connecting screw 402 to rotate, and the length of the tensioning mechanism 4 needs to be gradually reduced. At this time, the L-shaped connecting piece 110 will be clamped into the inside of the clamping groove 405, and drive the supporting and fixing mechanism 1 to be clamped on both sides of the hospital bed 5, and the connecting rod 2 connected with the waist clamping mechanism 3 needs to be inserted into the inside of the plug-in through hole 104, and the fixed threaded shaft 105 needs to be rotated to fix the waist clamping mechanism 3. It is screwed into the first threaded connection hole 202 to connect the extrusion push plate 102 and the connecting rod 2 together. The rotating adjustment screw 109 drives the extrusion push plate 102 to move. The movement of the extrusion push plate 102 will drive the connecting rod 2 to move, and then drive the waist clamping mechanism 3 to squeeze and clamp on both sides of the patient's waist. The valve core 304 is used to fill a certain amount of air into the close-fitting airbag 302. The close-fitting airbag 302 will expand and gradually fill the gap between the arc plate 301 and the patient's waist, so that the waist clamping mechanism 3 can fit the patient's waist and effectively fix and position the patient's limbs.
