[0032] Reference Figure 1-Figure 14 A tourniquet auxiliary winding device for operating room nursing comprises an upper support frame 1 and a lower support frame 2. The upper support frame 1 and the lower support frame 2 are both semicircular ring structures. The installation directions of the upper support frame 1 and the lower support frame 2 are arranged to face each other. One end of the upper support frame 1 and the lower support frame 2 are hinged to each other. When in use, the upper support frame 1 and the lower support frame 2 are sleeved on the patient's limbs. At this time, the lower support frame 2 will be pressed and fixed under the pressure of the patient's limbs. At this time, the upper support frame 1 and the lower support frame 2 are rotated to close. The closed upper support frame 1 and the lower support frame 2 are in a circular ring structure and are sleeved on the outside of the patient's limbs.

[0033] The side walls of the upper support frame 1 and the lower support frame 2 are both provided with a driving slide groove 3 with a semicircular arc structure, and the driving slide groove 3 on the upper support frame 1 and the driving slide groove 3 on the lower support frame 2 are connected to each other, and a driving slider 301 with a circular arc structure is slidably installed in the driving slide groove 3 on the upper support frame 1, and a plug interface 302 is provided on one side of the driving slider 3, and a winding module 4 with a circular arc structure is provided on the side of the upper support frame 1 where the driving slide groove 3 is provided, and a plug-in rod 401 is fixedly installed on the side of the winding module 4 close to the driving slide groove 3, and the plug-in rod 401 is plugged into the plug interface 302. After closing, the two driving slide grooves 3 on the upper support frame 1 and the lower support frame 2 are connected to each other to form a circular ring structure, and the connected driving slide groove 3 can realize the reciprocating sliding of the driving slider 301, and the driving slider 301 is connected to the winding module 4 through the plug interface 302 and the plug-in rod 401. Driven by the driving slider 301, the winding module 4 can move along the patient's limbs to realize the winding of the tourniquet.

[0034] A mounting groove 402 is provided in the winding module 4, and a plurality of spring grooves 403 with arc-shaped structures are provided on both sides of the inner wall of the mounting groove 402, and a return spring 404 is inserted in the spring groove 403. The plurality of spring grooves 403 on both sides of the inner wall of the mounting groove 402 correspond to each other one by one, and a support shaft 405 is slidably installed between the corresponding spring grooves 403, and the support shaft 405 is fixedly connected to one end of the corresponding return spring 404, and a fixed shaft is fixedly installed on the inner wall of the mounting groove 402 and above the plurality of spring grooves 403, and a plurality of auxiliary shafts 406 are rotatably installed on the inner wall of the mounting groove 402 and below the fixed shaft, and the installation positions of the plurality of auxiliary shafts 406 are respectively located between the plurality of spring grooves 403, and a through groove 407 is provided at one end of the winding module 4, and the through groove 407 is connected with the mounting groove 402, and a tourniquet is fixedly installed on the fixed shaft, and the tourniquet is wound around the plurality of support shafts 405 and the plurality of auxiliary shafts 406 and extends through the through slot 407 to the outside of the winding module 4. When the tourniquet is being wound, one end of the tourniquet is fixed on the patient's limb, and the remaining tourniquet is wound along the patient's limb under the drive of the winding module 4. The tourniquet in the mounting slot 402 will be tightened by the plurality of support shafts 405 and the auxiliary shaft 406 in the initial state, and is arranged in the mounting slot 402 in a folded state. When the tourniquet is pulled, the plurality of support shafts 405 will be driven to slide along the corresponding spring slot 403 and squeeze the reset spring 404. When the tourniquet is pulled to the specified position, the plurality of support shafts 405 and the plurality of auxiliary shafts 406 will be driven to approach each other. When the tourniquet is released, the elastic force of the reset spring 404 will cause the support shaft 405 to tighten the tourniquet again and fold it, thereby realizing the retraction of the tourniquet. The end of the winding module 4 away from the through slot 407 is in an arc-shaped structure, which can improve the smoothness of the winding module 4 when moving.

[0035] Two symmetrically arranged limit rollers 409 are rotatably installed on the inner wall of the through groove 407. The two limit rollers 409 are respectively arranged at the top and bottom of the tourniquet and are in contact with the tourniquet. A number of evenly distributed limit teeth 410 are fixedly installed on the outer wall of the limit roller 409. A limit groove 411 is provided on the outer wall of the limit roller 409. A limit slide groove 412 is provided on the inner wall of the through groove 407. A limit rod 413 is slidably installed in the limit slide groove 412. The installation position of the limit rod 413 corresponds to the opening position of the limit groove 411. The limit roller 409 is used to release the tourniquet. The limit groove 412 plays a guiding role in the extension and retraction. An electric telescopic rod is fixedly installed in the limit slide groove 412, and the telescopic tube of the electric telescopic rod is fixedly installed on the limit rod 413. The limit rod 413 can be pushed close to the limit roller 409 by extending the electric telescopic rod. When the limit groove 411 on the limit roller 409 is plugged into the limit rod 413, the two limit rollers 409 will be stuck and cannot continue to rotate under the resistance of the limit rod 413. At this time, the tourniquet can be clamped by the limit teeth 410 on the outer wall of the limit roller 409, so that the tourniquet is fixed and cannot be pulled further.

[0036] An adjusting slot 201 is provided on the inner ring wall of the lower support frame 2, and an adjusting plate 202 with an arc-shaped structure is slidably installed in the adjusting slot 201. A placement slot 203 is provided on the top of the adjusting plate 202, and a pressure plate 204 is inserted in the placement slot 203. One end of the pressure plate 204 extends out of the placement slot 203, and one end of the tourniquet extending out of the winding module 4 is inserted on the pressure plate 204. A pressure sensing unit is fixedly installed on the outer wall of the pressure plate 204, and a winding shaft 205 is rotatably installed in the adjusting plate 202, and a winding rope 206 is fixedly installed on the winding shaft 205, and the winding rope 206 is away from the winding shaft 20 One end of the adjusting plate 202 extends into the placement slot 203 and is fixedly mounted on the pressure plate 204. An electric slider is slidably mounted in the adjusting slot 201. The electric slider is fixedly connected to the bottom of the adjusting plate 202. Driven by the electric slider, the adjusting plate 202 can slide back and forth in the adjusting slot 201. The reel 205 is electrically driven. When the tourniquet is driven by the winding module 4 to wrap around the outside of the pressure plate 204, the pressure plate 204 will be pressed against the patient's limbs. When the pressure plate 204 is compressed by the tourniquet, the reel 205 is operated to release the reel rope 206, so that the pressure plate 204 is smoothly pressed. The pressure plate 204 is pressed on the patient's limbs, and the pressure sensing unit on the outer wall of the pressure plate 204 can monitor the winding pressure of the tourniquet to avoid damage to the patient's limbs caused by excessively tight winding of the tourniquet, and to avoid the tourniquet being too loose and unable to achieve the hemostatic effect. After the tourniquet is wound, the winding shaft 205 is operated to stop rotating so that the released winding rope 206 maintains a specified length. At this time, the adjustment plate 202 is operated to move in a specified direction to drive the inner end of the tourniquet after winding to move. In conjunction with the continued movement of the winding module 4, the inner and outer ends of the tourniquet after winding can be tightened to improve the winding effect of the tourniquet. When releasing the tourniquet, the winding module 4 is operated to move in the reverse direction to release the tourniquet. At the same time, the adjustment plate 202 is operated to be reset, so that the tourniquet can be released from both ends after being wound, thereby improving the release speed of the tourniquet and solving the problem that conventional tourniquets need medical staff to manually untie and release the tourniquet, which is slow in efficiency. At the same time, while the adjustment plate 202 is reset, the reeling rope 206 is operated to reel in the reeling rope 206, and the pressure plate 204 is pulled to be reinserted into the placement slot 203. The reverse resistance of the pressure plate 204 can further improve the release speed of the tourniquet.

[0037] A number of evenly distributed auxiliary rollers 207 are rotatably installed on the top of the adjustment plate 202, and a circular arc-shaped positioning spring piece 101 is fixedly installed on the inner ring wall of the upper support frame 1. The outer walls of the positioning spring piece 101 and the auxiliary roller 207 are wrapped with a buffer layer. The auxiliary roller 207 on the top of the adjustment plate 202 can improve the smoothness of the movement of the adjustment plate 202 to prevent the patient's limbs from pressing on the adjustment plate 202 and affecting the movement of the adjustment plate 202. The positioning spring piece 101 can fix the patient's limbs after the upper support frame 1 and the lower support frame 2 are closed to prevent the patient's limbs from moving when the tourniquet is wrapped.

[0038] The inner wall of the driving slide groove 3 is provided with driving tooth grooves 303 evenly distributed along its circumference, and the bottom of the driving slider 301 is respectively provided with a driving groove 304 and a locking groove 305, a driving module 306 is inserted in the driving groove 304, and a locking module 307 is inserted in the locking groove 305. A telescopic groove 308 is provided in the driving slider 301, and both ends of the telescopic groove 308 are respectively connected with the driving groove 304 and the locking groove 305, and an arc-shaped extrusion rod 309 is slidably installed in the telescopic groove 308, and both ends of the extrusion rod 309 are provided with inclined surfaces, and the extrusion rod 309 is slidably connected in the telescopic groove 308 through electric drive.

[0039] The driving module 306 has an arc-shaped structure. An inclined surface is provided on the top of the driving module 306 and corresponds to the inclined surface provided on the end of the squeezing rod 309. A plurality of driving gears 310 are rotatably installed on the bottom of the driving module 306. The driving gears 310 mesh with the driving tooth grooves 303. A spring rod 1 is fixedly installed between the top of the driving module 306 and the inner wall of the driving groove 304. When the squeezing rod 309 moves to a specified position in the direction of the driving groove 304, it will squeeze the driving module 306. The squeezed driving module 306 will move downward. The driving gear 310 on the moved driving module 306 will mesh with the driving tooth grooves 303. At this time, the driving gear 310 rotates under the drive of a driving motor with forward and reverse rotation functions, and can drive the driving slider 301 to move back and forth in the driving slide groove 3.

[0040] The locking module 307 is an arc-shaped structure. The top of the locking module 307 is provided with an inclined surface corresponding to the inclined surface provided at the end of the squeezing rod 309. The bottom of the locking module 307 is fixedly installed with a plurality of locking teeth 311 evenly distributed along its circumference. The installation position of the locking teeth 311 corresponds to the driving tooth groove 303. A spring rod 2 is fixedly installed between the top of the locking module 307 and the inner wall of the locking groove 305. When the tourniquet is wound, the squeezing rod 309 is operated to move toward the direction of the locking groove 305. At this time, , the squeezing rod 309 disengages from the driving module 306, and the driving module 306 automatically resets under the drive of the spring rod 1 and causes the driving gear 310 to disengage from the driving tooth groove 303. At this time, the squeezing rod 309 will contact the locking module 307 and squeeze it. The squeezed locking module 307 will extend downward and drive the locking tooth 311 to be inserted into the driving tooth groove 303 at the corresponding position. At this time, the driving slider 301 can remain in a fixed state under the positioning effect of the locking tooth 311, so that the tourniquet is tightened.

[0041] The specific working principle and method of use of the present invention are explained in detail below: when in use, first, the upper support frame 1 and the lower support frame 2 are sleeved on the patient's limbs. At this time, the lower support frame 2 will be pressed and fixed under the pressure of the patient's limbs. At this time, the upper support frame 1 and the lower support frame 2 are rotated to close. The closed upper support frame 1 and the lower support frame 2 are in a circular ring structure and sleeved on the outside of the patient's limbs. Handles are fixedly installed on the outer walls of the ends of the upper support frame 1 and the lower support frame 2 away from the hinged end. When in use, the medical staff can hold and hold them tightly for operation, or they can fix the two handles on the upper support frame 1 and the lower support frame 2 together by bundling, so that the upper support frame 1 and the lower support frame 2 are fitted and fixed to each other;

[0042] The electric slider is operated to drive the adjustment plate 202 to move in the adjustment slide groove 201 in the specified direction. When the tourniquet is wound to the outside of the pressure plate 204 under the drive of the winding module 4, the pressure plate 204 will be pressed against the patient's limbs. While the pressure plate 204 is pressed by the tourniquet, the reel 205 is operated to release the reel rope 206, so that the pressure plate 204 is smoothly pressed against the patient's limbs. The pressure sensing unit on the outer wall of the pressure plate 204 can monitor the winding pressure of the tourniquet to avoid damage to the patient's limbs caused by excessive tightness of the tourniquet, and to avoid the tourniquet being wound too loosely and failing to achieve the hemostatic effect. After the tourniquet is wound, the reel 205 is operated to stop rotating, so that the released reel rope 206 maintains the specified length. At this time, operating the adjustment plate 202 to move in the specified direction can drive the inner end of the tourniquet after being wrapped to move, and cooperating with the continued movement of the winding module 4, the inner and outer ends of the tourniquet after being wrapped can be tightened to improve the winding effect of the tourniquet. At the same time, when releasing the tourniquet, operating the winding module 4 to move in the opposite direction can release the tourniquet. At the same time, operating the adjustment plate 202 to reset can release the tourniquet from both ends after the tourniquet is wrapped, thereby increasing the release speed of the tourniquet. At the same time, while the adjustment plate 202 is reset, operating the reeling rope 206 to reel in the reeling rope 206, pull the pressure plate 204 to reinsert it into the placement slot 203, and the release speed of the tourniquet can be further increased through the reverse resistance of the pressure plate 204.

[0043] Through the reciprocating movement of the winding module 4 and the adjustment plate 202, and the reciprocating contraction and release of the pressure plate 204, the binding and release of the tourniquet can be automatically achieved. At the same time, in conjunction with the pressure sensing unit, adaptive adjustment can be made according to the patient's limb size and muscle firmness.

[0044] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
