Description
Technical Field
[0001] This utility model relates to a tourniquet wrapping device, specifically, a tourniquet wrapping device for operating room care. Background Technology
[0002] Tourniquets have wide applications in the medical field, including internal medicine, surgery, obstetrics and gynecology, and pediatrics. They are primarily used for emergency treatment of severe bleeding in the limbs, and are also used in routine medical procedures such as intravenous infusions, blood draws, and transfusions to temporarily block venous return. Furthermore, tourniquets are indispensable first-aid equipment in wilderness survival and military medical settings.
[0003] Existing tourniquets are usually in roll form, which are bulky and not easy to use quickly, especially in the operating room or emergency care stage. Due to time constraints, tourniquets are prone to knotting, increasing the complexity and time cost of the operation. In addition, when using tourniquets, medical staff often need to use scissors to cut them to the appropriate length, which not only affects the efficiency of use, but also increases the risk of contamination due to improper operation. Even if a winding device is used to organize tourniquets, the existing design often has shortcomings. Specifically, when these devices are used to store tourniquets, the protruding end of the tourniquet is easily wound into the device, making it difficult to quickly find and pull out the protruding end when used again, further delaying emergency treatment.
[0004] Therefore, there is an urgent need to provide a tourniquet wrapping device for operating room care to solve the above problems. Utility Model Content

[0006] The winding cylinder has a hollow structure, a winding cover is rotatably mounted on one side of the winding cylinder, an extension opening is provided on the outer periphery of the winding cylinder, an extension plate is provided on the outer periphery of the winding cylinder at the tangential position of the extension opening, a support rod is provided at the center of the winding cylinder, a one-way rotating component is provided on the support rod, a rotating sleeve is fitted on the support rod, the rotating sleeve is connected to the support rod through the one-way rotating component, and the tourniquet is rolled onto the rotating sleeve;
[0007] A limiting component is provided on the winding cylinder at the protrusion position to limit the tourniquet, and a blade is provided on the end of the extension plate away from the winding cylinder to cut the tourniquet.
[0008] As a further improvement to this technical solution, a control groove is provided on the extension plate, and the limiting component includes a squeezing roller, which is rotatably connected in the control groove. A rotating roller is rotatably connected to the winding cylinder at the protrusion. The squeezing roller has a cam structure, and the protrusion of the squeezing roller is in contact with the rotating roller.
[0009] As a further improvement to this technical solution, the support rod is rotatably connected inside the winding cylinder, and the top end of the support rod is adapted to the height of the winding cylinder. The bottom end of the support rod extends to the outside of the bottom of the winding cylinder, and a rotating disk is fixedly connected to one end of the support rod located outside the bottom of the winding cylinder. A handle is fixedly provided on the rotating disk.
[0010] As a further improvement to this technical solution, an installation groove is provided inside the rotating sleeve, and a clamping spring is fixed on the installation groove. The length of the clamping spring is adapted to the height of the winding cylinder and is used to clamp the tourniquet.
[0011] As a further improvement to this technical solution, the unidirectional rotation assembly includes a ratchet, which is fixedly connected inside the rotating sleeve. The ratchet has several teeth fixedly arranged inside it. A sliding cavity is formed inside the support rod at the position of the ratchet. A telescopic pawl is slidably connected inside the sliding cavity. One end of the telescopic pawl away from the center of the support rod has a wedge-shaped structure. A spring is provided inside the sliding cavity. One end of the spring is fixedly connected to the inner wall of the sliding cavity, and the other end is fixedly connected to the telescopic pawl. The wedge-shaped structure of the telescopic pawl is adapted to the distance between two adjacent teeth in the ratchet.

[0033] Please see Figures 1-7As shown, the purpose of this embodiment is to provide a tourniquet wrapping device for operating room care, including a wrapping cylinder 1, which has a hollow structure. A wrapping cover 2 is rotatably provided on one side of the wrapping cylinder 1. An extension port 4 is provided on the outer periphery of the wrapping cylinder 1. An extension plate 3 is provided on the outer periphery of the wrapping cylinder 1 at the tangential position of the extension port 4. A support rod 8 is provided at the center of the wrapping cylinder 1. The support rod 8 is rotatably connected inside the wrapping cylinder 1, and the top end of the support rod 8 is adapted to the height of the wrapping cylinder 1. The bottom end of the support rod 8 extends to the outside of the bottom of the wrapping cylinder 1. A rotating disk 13 is fixedly connected to the end of the support rod 8 located outside the bottom of the wrapping cylinder 1. A handle is fixedly provided on the rotating disk 13.
[0034] Furthermore, a one-way rotating component 10 is provided on the support rod 8, and a rotating sleeve 9 is fitted on the support rod 8. The rotating sleeve 9 is connected to the support rod 8 through the one-way rotating component 10, and the tourniquet is rolled onto the rotating sleeve 9.
[0035] Specifically, the unidirectional rotation assembly 10 includes a ratchet 101, which is fixedly connected inside the rotating sleeve 9. The ratchet 101 has a number of teeth fixed inside. A sliding cavity 102 is provided inside the support rod 8 at the position of the ratchet 101. A telescopic pawl 103 is slidably connected inside the sliding cavity 102. The end of the telescopic pawl 103 away from the center of the support rod 8 has a wedge-shaped structure. A spring 104 is provided inside the sliding cavity 102. One end of the spring 104 is fixedly connected to the inner wall of the sliding cavity 102, and the other end is fixedly connected to the telescopic pawl 103. The wedge-shaped structure of the telescopic pawl 103 is adapted to the distance between two adjacent teeth inside the ratchet 101. The telescopic pawl 103 is used to limit the unidirectional rotation of the ratchet 101.
[0036] The rotating sleeve 9 has an installation groove 11, and a clamping spring 12 is fixed on the installation groove 11. The length of the clamping spring 12 is adapted to the height of the winding cylinder 1 and is used to clamp the tourniquet.
[0037] Furthermore, a limiting component 6 is provided on the winding cylinder 1 at the protrusion 4 position to limit the tourniquet. A control groove 5 is provided on the extension plate 3. The limiting component 6 includes a squeezing roller 61, which is rotatably connected in the control groove 5. A rotating roller 62 is rotatably connected on the winding cylinder 1 at the protrusion 4 position. The squeezing roller 61 has a cam structure, and the protrusion of the squeezing roller 61 is in contact with the rotating roller 62.
[0038] In addition, a blade 7 is provided on the end of the extension plate 3 away from the winding cylinder 1 for cutting the tourniquet.
[0039] The specific working principle is as follows:
[0040] In practice, one end of the tourniquet is passed between the compression roller 61 and the rotating roller 62, that is, through the protrusion 4. Then, one end of the tourniquet is placed on the rotating sleeve 9, and the clamping spring 12 is lifted to clamp one end of the tourniquet onto the rotating sleeve 9. Then, the handle on the rotating disk 13 can be rotated. The rotation of the rotating disk 13 drives the support rod 8 to rotate. Due to the presence of the ratchet 101 and the telescopic pawl 103, the rotation of the support rod 8 drives the rotation of the rotating sleeve 9, thus causing the tourniquet to gradually wrap around the rotating sleeve 9. The rotating disk 13 makes wrapping the tourniquet easier and more convenient. The clamping spring 12 is designed so that its end can be removed from the rotating sleeve 9 when storing or using the tourniquet. Furthermore, whether storing or using the tourniquet, the cooperation of the compression roller 61 and the rotating roller 62 provides a stable path for the tourniquet, allowing it to begin wrapping smoothly. Finally, the tourniquet passes between the compression roller 61 and the rotating roller 62 to prevent it from tangling. After the tourniquet is properly stored, that is, after it has been unwound from the rotating sleeve 9, the wrapping cap 2 can be closed. This makes it easy to carry during use and prevents the tourniquet from getting dirty or unraveling if it falls. It should be noted that after the tourniquet is wrapped, it can be cut with the blade 7. That is, by holding the wrapping sleeve 1 and then slicing the tourniquet across the blade 7, it can be easily cut. After the tourniquet is cut, there will be an end. At this time, the end needs to be located on the side of the compression roller 61 and the rotating roller 62 away from the center. At the same time, rotate the compression roller 61 so that the protrusion of the compression roller 61 is in contact with the rotating roller 62. In this way, the end of the tourniquet is limited between the compression roller 61 and the rotating roller 62, and the end, that is, the protruding end of the tourniquet, will not be retracted into the wrapping sleeve 1 and become difficult to pull out.
[0041] Furthermore, if a tourniquet is needed, the squeeze roller 61 is rotated by rotating one side of the exposed squeeze roller 61 on the extension plate 3, causing the protrusion of the squeeze roller 61 to disengage from the rotating roller 62. This releases the tourniquet from its restraint, allowing it to be easily pulled out. After pulling it out to the required length, the tourniquet is cut by passing it across the blade 7. This is convenient and quick. After use, the squeeze roller 61 is rotated again to make the protrusion of the squeeze roller 61 engage with the rotating roller 62, thus maintaining the restraint on the extended end of the tourniquet. This effectively solves the problems of existing tourniquets being prone to knotting during use, requiring additional scissors for acute cutting of the tourniquet, and the winding device causing the extended end to get caught inside the device, affecting the efficiency of subsequent use.
[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
