Description

Technical Field

[0001] This invention belongs to the field of medical device technology, and specifically discloses a tourniquet wrapping device for operating room nursing. Background Technology

[0002] When operating room nurses care for patients' wounds, they need to wrap tourniquets around the wounds. Currently, the tourniquet wrapping method is usually based on the nurses' own experience, which makes the wound care of patients very uncertain. According to the existing tourniquet manufacturing process, the tourniquet must be made longer than the actual required length. The advantage of this design is that it allows tourniquets to be used by people of different body types and prevents the tourniquet from separating from the patient's wound when dealing with a sudden clinical situation. Although a tourniquet longer than the actual required length can effectively prevent the tourniquet from separating from the patient's wound, an excessively long tourniquet can also cause a lot of inconvenience to the patient. In this case, medical staff need to cut the excessively long tourniquet. To enable healthcare professionals to select the appropriate tourniquet length based on the patient's body size when applying a tourniquet to the wound, a tourniquet wrapping device has emerged on the market. This device includes a tourniquet storage structure and a tourniquet cutting structure. In actual use, healthcare professionals pre-place the tourniquet inside the device and then cut it to the appropriate length to apply to the patient's wound, thus making tourniquet application to the patient's wound convenient. The aforementioned tourniquet wrapping device can indeed increase the portability of wound care for patients. However, it requires the tourniquet to be pre-inserted into the device during use, which makes it inconvenient for medical staff to observe the length of the tourniquet inside the device and thus cannot determine whether the tourniquet inside the device meets the requirements for wound care. Meanwhile, the excessively long tourniquet is pre-inserted into the wrapping device, and then the wrapping device pulls the tourniquet to wrap around the patient's wound. After the tourniquet is separated from the wrapping device, it reduces the portability of medical staff in caring for the patient's wound and also leads to the patient's wound being exposed for too long, thereby increasing the risk of secondary infection of the patient's wound. Summary of the Invention

[0003] In view of this, the object of the present invention is to provide a tourniquet wrapping device for operating room care, so as to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention provides a tourniquet wrapping device for operating room care, including a gripping piece and side plates snapped onto both sides of the gripping piece. A tourniquet body is penetrated inside the cavity formed by the gripping piece and the side plates. A first compression rod and a second compression rod slide through the gripping piece. The second compression rod is used to compress the tourniquet body, so that the tourniquet body has appropriate tension when wrapped around the patient's wound. A cutter is fixed to the inner wall of the gripping piece on one side of the first compression rod. When the first compression rod compresses the tourniquet body, the cutter cuts the tourniquet body. At the same time, the inner wall of the gripping piece is provided with a locking structure to fix the first compression rod. When the first compression rod drives the tourniquet body to cut on the cutter, the locking structure fixes the first compression rod, thereby realizing the compression and fixation of the tourniquet body by the first compression rod, and thus allowing the gripping piece to fix the tourniquet body at the patient's wound care site.

[0005] In the above technical solution, a cotton sleeve is further fitted onto the outside of the cavity formed by the two side plates and the gripping piece. The cotton sleeve is elastic, and the outer wall of the side plate is rough.

[0006] In the above technical solution, the second squeezing rod and the first squeezing rod are further provided with a pressing block at the end opposite to the gripping piece, and the second squeezing rod and the first squeezing rod are provided with an inclined surface at the end inserted into the gripping piece, the inclined surface being inclined towards the tourniquet body and penetrating through one end of the gripping piece.

[0007] In the above technical solution, further, two rotating rollers rotate on the inner wall of the gripping piece opposite to the second compression rod. The rotating rollers abut against the tourniquet body, and the length of the rotating rollers is greater than the width of the tourniquet body.

[0008] In the above technical solution, a mounting plate is further fixed on the second extrusion rod, and a first sliding groove is provided on the side wall of the gripping piece. The mounting plate slides inside the first sliding groove, and a connecting spring is fixed between the mounting plate and the gripping piece.

[0009] In the above technical solution, the side wall of the gripping piece is provided with a second sliding groove, the engaging structure includes a snap-fit ​​block that slides inside the second sliding groove, a plug-in rod is fixed on the gripping piece, a limiting rubber ball is fixed on the plug-in rod, and the limiting rubber ball and the plug-in rod pass through the snap-fit ​​block.

[0010] In the above technical solution, the limiting rubber ball is elastic, the diameter of the limiting rubber ball is larger than the hole through which the plug rod passes through the snap-fit ​​block, and the limiting rubber ball abuts against the snap-fit ​​block.

[0011] In the above technical solution, the gripping piece is further provided with a squeezing notch, the first squeezing rod is inserted into the inside of the squeezing notch, and the inner wall of the squeezing notch is rough.

[0012] In the above technical solution, further, a separation groove is provided on the inner wall of the holding piece on the side of the cutter away from the first extrusion rod. The separation groove is trapezoidal in shape, and the cutter is in contact with the first extrusion rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. When the pressing block in this wrapping device drives the second extrusion rod to extrude the tourniquet body on the rotating roller, it can adjust the tourniquet body to the patient's wound site by the gripping plate. This ensures that the tourniquet body wrapped around the patient's wound site has appropriate tension, while preventing the tourniquet body from penetrating the medical staff's hands and scratching their hands when wrapped around the patient's wound. This conforms to the medical staff's habit of wrapping the tourniquet body around the patient's wound site, making it easier for medical staff to quickly become familiar with the use of the device and improving the portability of the device for the medical staff to care for the patient's wound site.

[0014] 2. The side plate of the wrapping device can be made of transparent material, which allows medical staff to intuitively understand the length of the tourniquet body reserved in the grip. At the same time, the little finger of the medical staff can use the pressing block to drive the first compression rod to squeeze the tourniquet body. At this time, the cutter can cut the right end of the tourniquet body, which makes it easier for medical staff to cut the tourniquet body to the appropriate length according to the patient's body size, and thus facilitates the medical staff to wrap the patient's wound.

[0017] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0019] Please see Figures 1-8 As shown, the present invention provides a technical solution: This invention is a tourniquet wrapping device for operating room care, including a gripping piece 2 and side plates 21 snapped onto both sides of the gripping piece 2. The tourniquet body 1 passes through the cavity formed by the gripping piece 2 and the side plates 21. A first compression rod 22 and a second compression rod 24 slide through the gripping piece 2. The second compression rod 24 and the first compression rod 22 are located on the top and bottom surfaces of the left and right ends of the gripping piece 2, respectively. The second compression rod 24 is used to compress the tourniquet body 1, so that the tourniquet body 1 has appropriate tension when wrapped around the patient's wound. The tourniquet body 1 is a disposable elastic bandage commonly used in operating rooms. A cutter 28 is fixed to the inner wall of the gripping piece 2 on one side of the first compression rod 22. When the first compression rod 22 compresses the tourniquet body 1, the cutter 28 cuts the tourniquet body 1. At the same time, the inner wall of the gripping piece 2 is provided with a locking structure to fix the first compression rod 22. When the first compression rod 22 drives the tourniquet body 1 to cut on the cutter 28, the locking structure fixes the first compression rod 22, thereby squeezing and fixing the tourniquet body 1 with the first compression rod 22, and thus fixing the tourniquet body 1 with the gripping piece 2 at the patient's wound care site.

[0020] The cavity formed by the two side plates 21 and the grip piece 2 is fitted with a cotton sleeve 25. The cotton sleeve 25 is elastic, and the outer wall of the side plate 21 is rough.

[0021] The second squeezing rod 24 and the first squeezing rod 22 are fixed with a pressing block 23 at the ends opposite to the gripping piece 2. The ends of the second squeezing rod 24 and the first squeezing rod 22 that are inserted into the gripping piece 2 are provided with inclined surfaces. The inclined surfaces are inclined in the direction of the tourniquet body 1 and penetrate through one end of the gripping piece 2.

[0022] Two rotating rollers 31 rotate on the inner wall of the gripping piece 2 opposite to the second compression rod 24. The rotating rollers 31 abut against the tourniquet body 1, and the length of the rotating rollers 31 is greater than the width of the tourniquet body 1.

[0023] A mounting plate 32 is fixed on the second extrusion rod 24. A first groove 33 is provided on the side wall of the gripping piece 2. The mounting plate 32 slides inside the first groove 33. At the same time, a connecting spring 3 is fixed between the mounting plate 32 and the gripping piece 2.

[0024] Please refer to the instruction manual attached. Figure 2 In actual use, medical personnel should first insert the tourniquet body 1 through the right end of the grip piece 2. When the tourniquet body 1 is relatively soft, medical personnel can remove the side plate 21 on one side of the grip piece 2, then insert the tourniquet body 1 through the grip piece 2, and then fix the side plate 21 to the grip piece 2. Please refer to the instruction manual. Figure 1 The length of the tourniquet body 1 penetrating the gripping piece 2 is set according to the actual situation; When the tourniquet body 1 passes through the gripping piece 2, the medical staff holds the end of the tourniquet body 1 with one hand and the cotton sleeve 25 with the other hand. Then, the medical staff's thumb presses the left-side pressing block 23 to drive the second squeezing rod 24 to squeeze the tourniquet body 1 on the rotating roller 31. When the second squeezing rod 24 squeezes the tourniquet body 1 on the rotating roller 31, the connecting spring 3 on the mounting plate 32 stores power. When the medical staff's thumb does not drive the second squeezing rod 24 to squeeze the tourniquet body 1 on the rotating roller 31 through the pressing block 23, the connecting spring 3 can drive the second squeezing rod 24 to separate from the tourniquet body 1 under its own restoring force. By pressing the first squeezing rod 22 and cooperating with the locking structure, the end of the tourniquet body 1 is squeezed and fixed. Then, the medical staff's hand drives the tourniquet body 1 to wrap around the patient's wound through the gripping piece 2, so that the tourniquet body 1 can be stably wrapped around the patient's wound. When the medical staff's thumb drives the second squeezing rod 24 to squeeze the tourniquet body 1 on the rotating roller 31 through the left pressing block 23, the gripping piece 2 can adjust the tourniquet body 1 to the patient's wound site, so that the tourniquet body 1 wrapped around the patient's wound site has appropriate tension. At the same time, it avoids the tourniquet body 1 from scratching the medical staff's hand when it is wrapped around the patient's wound. Therefore, when the medical staff wraps the tourniquet body 1 around the patient's wound site through this device, it conforms to the medical staff's habit of wrapping the tourniquet body 1 around the patient's wound site, and makes it easy for the medical staff to quickly become familiar with the use of the device. When medical staff wrap the tourniquet body 1 around the patient's wound using the device, the tourniquet body 1 can completely penetrate through the inside of the grip piece 2. Then, the medical staff can place the device in a suitable position for subsequent reuse. Then, the medical staff can hold the end of the tourniquet body 1 with their hand to tie the end of the tourniquet body 1 to the beginning of the tourniquet body 1, thereby completing the tourniquet body 1 being tied to the patient's wound.

[0025] To ensure effective pressure and hemostasis of the patient's wound, existing tourniquets are typically elastic. This elasticity allows the tourniquet to conform well to the wound. However, some highly elastic tourniquets, when knotted, may compromise the tightness of the seal due to their own elasticity. To avoid this, please refer to [the relevant documentation / reference needed]. Figures 1-8 As shown, the present invention provides another technical solution: The tourniquet wrapping device for operating room nursing includes a gripping piece 2, the side wall of which has a second groove 42. The engaging structure includes a snap-fit ​​block 26 that slides inside the second groove 42. The snap-fit ​​block 26 is fixedly connected to the side wall of the first compression rod 22. A plug-in rod 4 is fixed on the gripping piece 2. A limiting rubber ball 41 is fixed on the plug-in rod 4. The limiting rubber ball 41 and the plug-in rod 4 pass through the snap-fit ​​block 26.

[0026] The limiting rubber ball 41 is elastic, and the diameter of the limiting rubber ball 41 is larger than the hole through which the plug rod 4 passes through the snap-fit ​​block 26. The limiting rubber ball 41 abuts against the snap-fit ​​block 26.

[0027] The gripping piece 2 has a compression notch 27, and the first compression rod 22 is inserted into the inside of the compression notch 27. The inner wall of the compression notch 27 is rough.

[0028] The inner wall of the gripping piece 2 is provided with a separation groove 29 on the side of the cutter 28 away from the first extrusion rod 22. The separation groove 29 is trapezoidal in shape, and the cutter 28 is in contact with the first extrusion rod 22. Please refer to the instruction manual attached. Figure 2 When medical staff use the grip 2 to wrap the tourniquet body 1 around the patient's wound, the length reserved inside the grip 2 for the tourniquet body 1 needs to be greater than the length between the left end of the grip 2 and the cutter 28. The side plate 21 can be made of transparent material so that medical staff can intuitively understand the length of the tourniquet body 1 reserved in the grip 2 through the side plate 21. When the medical staff's hand holds the cotton sleeve 25, the medical staff's little finger can use the pressing block 23 to drive the first squeezing rod 22 to squeeze the tourniquet body 1. At this time, the cutter 28 can cut the right end of the tourniquet body 1. Because the side plate 21 of the wrapping device is made of transparent material, medical staff can easily see the length of the tourniquet body 1 reserved inside the grip 2 through the side plate 21. Then, by cutting the right end of the tourniquet body 1 with the cutter 28, medical staff can easily cut the tourniquet body 1 to the appropriate length for use according to the different body types of patients. Simultaneously, the part of the tourniquet body 1 near the right end will enter the compression notch 27 under the action of the first compression rod 22. The limiting rubber ball 41 will puncture the tourniquet body 1 due to its own elasticity. At the same time, the limiting rubber ball 41 is fixed to the snap-fit ​​block 26. Because the tourniquet body 1 is elastic, when the limiting rubber ball 41 and the insertion rod 4 penetrate the snap-fit ​​block 26, the tourniquet body 1 can be punctured by the limiting rubber ball 41 under its own tension, thereby fixing the limiting rubber ball 41 to the snap-fit ​​block. Regarding point 26, it should be noted that when the limiting rubber ball 41 punctures the tourniquet body 1 locally, the puncture holes distributed on the tourniquet body 1 are only distributed at the fixed end of the tourniquet body 1 and will not affect the normal care of the patient's wound site by the tourniquet body 1. When the insertion rod 4 penetrates the locking block 26, the limiting rubber ball 41 can abut against the locking block 26, thereby enabling the first compression rod 22 to drive the end of the tourniquet body 1 to be fixed in the compression notch 27, thereby fixing the tourniquet body 1 to the device.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
