[0025] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0026] Depend on Figures 1 to 8 The present invention relates to a tourniquet pressurizing device, comprising a base 1, wherein the upper surface of the base 1 is provided with a placement groove 3 for accommodating the tourniquet body 2, and a locking component is provided at one end of the placement groove 3 for fixing the fixed end 4 of the tourniquet body 2.

[0027] The base 1 has a sliding groove 5 inside the corresponding placement slot 3. An arc rod 6 is slidably installed in the sliding groove 5. The arc rod 6 can extend out of or into the base 1 through the sliding groove 5. A fastening component is provided at one end of the arc rod 6. The fastening component is used to fix the movable end 7 of the tourniquet body 2.

[0028] In these embodiments, the base 1 is a U-shaped base, which can stably place the patient's limb. The placement groove 3 allows the tourniquet body 2 to be pre-positioned under the affected limb, facilitating the fixation and application of the tourniquet body 2 after the affected limb is positioned. A locking assembly securely fixes the fixed end 4 of the tourniquet body 2 to the base 1, and the placement groove 3 allows the tourniquet body 2 to wrap around the affected limb at an appropriate position. Then, a fastening assembly fixes the movable end 7 of the tourniquet body 2 to the arc rod 6. Figure 6 As shown, the tourniquet body 2 wraps around the affected limb to form a pressure ring for applying pressure. Then, the movement of the arc rod 6 in the groove 5 causes the fastening component to extend into the groove 5, thereby causing the movable end 7 to extend into the groove 5. This tightens the tourniquet body 2 around the affected limb, achieving stable pressure. Through the cooperation of the locking component, fastening component, and arc rod 6, the tourniquet body 2 is firmly fixed, preventing loosening due to the smoothness of the tourniquet body 2, ensuring the reliability and effectiveness of pressure fixation, effectively improving safety, and enabling rapid and stable pressure application to the affected limb. The pressure level is also easier to control, ensuring the stability and comfort of pressure application to the affected limb. The operation is convenient and efficient, greatly reducing the workload of medical personnel, improving hemostasis, and offering greater flexibility, adaptability, and practicality.

[0029] In some embodiments of a tourniquet pressure device, the locking component includes a positioning seat 8, which is fixedly connected to one end of the placement groove 3. The positioning seat 8 has a positioning hole 9 that communicates with the placement groove 3, and the fixed end 4 is detachably installed in the positioning hole 9.

[0030] In these embodiments, the positioning seat 8 has an arc-shaped curved surface on one side relative to the placement groove 3 to facilitate conforming to the affected limb and thus ensure comprehensive pressure application. The positioning hole 9 is curved and passes through the positioning seat 8 and communicates with the placement groove 3, allowing the fixed end 4 of the tourniquet body 2 to be stably installed in the positioning hole 9, thereby ensuring that the rest of the tourniquet body 2 can be stably placed in the placement groove 3. In addition, since the tourniquet body 2 needs to be wrapped around the affected limb, that is, the part of the tourniquet body 2 near the movable end 7 extends out of the placement groove 3, in actual use, it can be temporarily placed on the base 1, the affected limb is placed on the base 1, and then the movable end 7 of the tourniquet body 2 is wrapped around the affected limb and fixed to the fastening component. This not only better meets the actual use requirements but also makes it easier for medical personnel to operate and use.

[0031] In some embodiments of a tourniquet pressure device, a locking seat 10 is formed on one side of the positioning seat 8, and a locking rod 11 passes through the locking seat 10. The locking rod 11 can extend into the positioning hole 9 and is used to restrict the fixed end 4 in the positioning hole 9. The locking rod 11 and the locking seat 10 are threaded together.

[0032] In these embodiments, by means of the threaded engagement between the locking rod 11 and the locking seat 10, the locking rod 11 is rotated to extend into or out of the positioning hole 9, thereby fixing the fixed end 4 in the positioning hole 9, or releasing the fixing end 4 from the positioning hole 9, making installation and removal simpler and more flexible, while also ensuring a firm and reliable installation of the fixed end 4 of the tourniquet body 2, thereby ensuring the stability of the pressure.

[0033] In some embodiments of a tourniquet pressure device, a relief groove 12 is formed on the outer surface of the positioning seat 8. The relief groove 12 is connected to the sliding groove 5, and the tourniquet body 2 can slide through the relief groove 12.

[0034] In these embodiments, the relief groove 12 is an arc-shaped curved groove. The relief groove 12 can stably support the tourniquet body 2 and ensure that it can smoothly extend into the sliding groove 5, thereby improving the stability when pressurized. In addition, the relief groove 12 is also connected to the positioning hole 9, which makes it easier to load and unload the tourniquet body 2.

[0035] In some embodiments of a tourniquet pressure device, the fastening assembly includes a fixing seat 13, which is fixedly connected to one end of the arc rod 6. A fixing cavity 14 is formed in the middle of the fixing seat 13, and the movable end 7 is detachably installed in the fixing cavity 14.

[0036] In some embodiments of a tourniquet pressure device, a fixing rod 15 extends through the top of the fixing seat 13. The fixing rod 15 can extend into the fixing cavity 14 and is used to restrict the movable end 7 in the fixing cavity 14. The fixing rod 15 and the fixing seat 13 are threaded together.

[0037] In these embodiments, the movable end 7 of the tourniquet body 2 can be securely installed on the fixed seat 13 through the cooperation of the fixed cavity 14 and the fixed rod 15. Then, as the arc rod 6 extends into the slide groove 5, the movable end 7 is driven into the slide groove 5 by the fixed seat 13, thereby tightening and pressurizing the tourniquet body 2. Through the threaded engagement between the fixed rod 15 and the fixed seat 13, the fixed rod 15 can be rotated to extend into or out of the fixed cavity 14, thereby fixing or removing the movable end 7. The operation is simpler and more flexible, ensuring that the movable end 7 of the tourniquet body 2 is securely installed and that the pressure level can be flexibly adjusted. It should be understood that both the fixed end 4 and the movable end 7 are fixed by pressing, which can effectively prevent the tourniquet body 2 from loosening due to smoothness, thus improving the safety of pressurization.

[0038] In some embodiments of a tourniquet pressure device, a guide groove 16 is formed on the inner sidewall of the slide groove 5, and a guide rod 17 is formed on the outer surface of the arc rod 6. The guide rod 17 is slidably installed in the guide groove 16, and a scale line is formed on the outer surface of the guide rod 17.

[0039] In these embodiments, the arc rod 6 can move stably in the slide groove 5 through the cooperation of the guide rod 17 and the guide groove 16, ensuring that the arc rod 6 can flexibly extend into or out of the two openings of the slide groove 5, better meeting the needs of flexible adjustment. Furthermore, the scale lines are preferably set on the outer surface of the end away from the fixed seat 13 (not shown in the figure). During the tightening and pressurization process, as the arc rod 6 extends out of the slide groove 5, the degree of tightening of the tourniquet body 2 can be observed in a timely manner through the scale lines on the guide rod 17, providing convenience for medical personnel to adjust the pressure level.

[0040] In some embodiments of a tourniquet pressure device, a mounting groove 18 communicating with a sliding groove 5 is formed in the base 1. A rotating rod 19 is rotatably mounted in the mounting groove 18. A driving gear 20 is fixedly mounted on the outer ring surface of the rotating rod 19. A driven gear 21 is formed on the outer surface of the arc rod 6. The driven gear 21 and the driving gear 20 are meshed. An adjustment component is connected to the rotating rod 19.

[0041] In these embodiments, the rotating rod 19 is rotated by the adjusting component, and then the driven gear 21 is rotated by the driving gear 20, thereby driving the arc rod 6 to move in the slide groove 5, ensuring that the arc rod 6 can slide stably.

[0042] In some embodiments of a tourniquet pressure device, the adjusting component includes a worm gear 22, which is fixedly installed on the outer ring surface of the rotating rod 19. A worm 23 is rotatably installed in the mounting groove 18. The worm gear 22 and the worm 23 are meshed together. One end of the worm 23 extends out of the base 1 and is fixedly installed with a rotating wheel 24.

[0043] In these embodiments, the rotation of the rotating rod 19 can be flexibly controlled through the cooperation of the worm gear 22 and the worm 23, thereby ensuring that the arc rod 6 slides stably in the groove 5. By rotating the wheel 24 to drive the worm 23, and then through the worm gear 22 to drive the rotating rod 19, the operation is more convenient. At the same time, the cooperation of the worm gear 22 and the worm 23 also has a self-locking effect, which allows the rotating wheel 24 to fix the arc rod 6 in a proper position, thereby ensuring the pressurization effect.

[0044] It should be understood that the tourniquet body 2 in the prior art is usually reusable, that is, a tourniquet body 2 is repeatedly loaded and unloaded. In order to further improve the convenience of use by medical staff, a disposable tourniquet body 2 can also be used. Specifically, in some embodiments of a tourniquet pressurization device, a storage box 25 is fixedly connected to one side of the base 1. A wheel 26 is rotatably installed in the storage box 25. The tourniquet body 2 is wound on the wheel 26. A limiting seat 27 is fixedly connected to the upper surface of the base 1. The tourniquet body 2 extends out of the storage box 25 and passes through the limiting seat 27. The tourniquet body 2 can be placed into the placement slot 3 through the locking component.

[0045] In these implementations, such as Figure 7-8 As shown, the disposable tourniquet body 2 is installed in the storage box 25 via the wheel 26. One end extends from the storage box 25, and pulling the tourniquet body 2 causes the wheel 26 to gradually release the tourniquet body 2, which then passes through the limiting seat 27 on the base 1, then through the positioning seat 8 in the locking assembly, and finally into the placement slot 3 through the positioning hole 9. During use, the tourniquet body 2 is pulled out to an appropriate length according to the needs, fixed to the base 1 by the locking assembly, then wrapped around the affected limb, and finally fixed to the arc rod 6 by the fastening assembly. Tightening and pressurization are completed as the arc rod 6 moves. After use, the tourniquet body 2 near the positioning seat 8 is cut off, thus disposing of the used tourniquet body 2. For the next use, simply pull out the tourniquet body 2 to an appropriate length again, and then fix and pressurize it in the same way as described above. This improves the convenience of use, greatly reduces the workload and difficulty for medical staff, and helps improve work efficiency.

[0046] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
