Description

Technical Field

[0001] This utility model relates to the field of medical technology, and in particular to a compression hemostasis device for intravenous puncture. Background Technology

[0002] In medical practice, venipuncture is a common procedure, typically used for blood collection, intravenous infusion, and catheter insertion. However, post-puncture bleeding is a concern, especially in patients with abnormal coagulation function or when hemostasis at the puncture site is difficult. Therefore, venipuncture compression hemostatic devices have emerged as essential tools for healthcare professionals in managing post-puncture bleeding.

[0003] Current puncture site compression techniques typically involve applying pressure to stop bleeding, covering the area with sterile gauze, and then securing it with a figure-eight bandage. This is achieved by crossing two bandages of different lengths around the thigh, with the crossing point above the puncture site, and then applying pressure with a ball bearing pressure. However, in daily use, the following problems still exist:

[0004] (a) Traditional bandage pressure bandaging is inconvenient to operate. During use, cotton swabs or gauze are easily displaced due to patient movement, affecting the hemostatic effect. Moreover, it often cannot adapt well to puncture points of different shapes and sizes, as well as the skin curvature of different parts.

[0005] (ii) Although tourniquets can provide a certain amount of pressure, traditional methods such as cotton swabs and gauze are difficult to ensure continuous and uniform pressure, which may lead to poor hemostasis. Utility Model Content

The advantages and features of this utility model will become clearer from the following description. It should be noted that the accompanying drawings are in a very simplified form and use non-precise proportions, used only to facilitate and clearly illustrate the purpose of the embodiments of this utility model. Please refer to the accompanying drawings to make the objectives, features, and advantages of this utility model more apparent and understandable. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are only for illustrative purposes to aid those skilled in the art and are not intended to limit the implementation conditions of this utility model. Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by this utility model, should still fall within the scope of the technical content disclosed in this utility model.

[0030] Please see Figures 1 to 7The intravenous puncture compression hemostasis device of this embodiment includes a fixation component 1, which includes a fixation strap 11 and a compression member 12. One end of the fixation strap 11 is connected to the compression member 12. The surface of the compression member 12 is provided with a first recess 121, and one end of the fixation strap 11 is provided with a first hole 111. The fixation strap 11 is rotatably fitted to the compression member 12 through the first hole 111 and the first recess 121. The surface of the fixation strap 11 is also provided with ventilation holes 112, thereby improving patient comfort and reducing skin discomfort caused by prolonged compression. Preferably, in this embodiment, six fixation straps 11 are provided. The fixation straps 11 are preferably low-sensitivity self-adhesive elastic bandages, which can adjust their direction and length relative to the compression member 12 to adapt to patients of different body types or different parts of the same patient's body, and can also increase patient skin comfort and reduce the risk of skin allergies. The portion of the compression member 12 that is in contact with the human skin is preferably made of an elastically expandable material, such as medical-grade silicone or polyurethane foam, and may be coated with benzalkonium chloride. This allows it to fit tightly around the puncture point, providing uniform pressure and preventing infection at the puncture site.

[0031] Furthermore, the device also includes an adjustment component 2, which cooperates with the pressure member 12 to increase or decrease the pressure on the pressure member 12.

[0032] Specifically, the surface of the aforementioned pressing member 12 is further provided with a second hole 122, and an inner wall 123 is formed along the second hole 122 into the pressing member 12. A second recess 124 is provided on the inner wall 123. The adjusting assembly 2 includes a pressure regulator 21, which is provided with a protrusion 211 that fits into the inner wall 123. A third recess 212 is provided on the surface of the protrusion 211. The device also includes a sealing ring 3, which is disposed in the third recess 212, and a portion of the sealing ring 3 also fits into the second recess 124. Through the provision of the protrusion 211, the inner wall 123, and the sealing ring 3, the pressure regulator 21 and the pressing member 12 are tightly connected, ensuring a sealing effect.

[0033] Furthermore, the adjustment component 2 also includes a knob 22, which is rotatably coupled to the pressure regulator 21. The knob 22 is connected to a pointer 221, and the surface of the pressure regulator 21 is also configured with a scale area 213 that mates with the pointer 221, to achieve precise pressure adjustment and help medical personnel control the hemostatic pressure more accurately. An openable and closable valve plate 214 is provided within the protrusion 211. When it is necessary to inflate or depressurize the compression member 12, the valve plate 214 is opened using known chip technology. After inflating or depressurizing the compression member 12, the valve plate 214 closes to ensure a constant pressure in the compression member 12. The knob 22 can be set to increase pressure by rotating clockwise and decrease pressure by rotating counterclockwise, i.e., to inflate or depressurize the compression member 12 via the pressure regulator 21. This allows medical personnel to adjust the pressure of the compression member 12 according to the patient's specific condition, achieving a personalized hemostatic effect.

[0034] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0035] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
