[0030] In addition, the meaning of the term "a plurality of" should be two and more than two.

[0031] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0032] Embodiment one:

[0033] As shown in Figures 1-2 A hemostatic patch, comprising a hemostatic patch body, a hemostatic cotton block fixedly arranged in the inner side of the middle part of the hemostatic patch body, a sticky segment arranged on both sides of the hemostatic cotton block respectively, and an isolation film matched with the sticky segment, a pressing protrusion is arranged between the hemostatic cotton block and the hemostatic patch body, the pressing protrusion has a pressing inclined surface, and the pressing inclined surface is inclined and extended from both ends of the hemostatic patch towards the hemostatic cotton block.

[0034] In order to reduce infection, the pressing protrusion is made of one of medical rubber, medical silicone and medical plastic, at least one of the above-mentioned materials is adopted, and has a certain elasticity, which can slow down the discomfort of the patient during pressing.

[0035] In the embodiment, the pressing protrusion is in a cylindrical shape, the pressing protrusion is fixedly connected with the hemostatic patch body, and the thickness of the part of the hemostatic cotton block opposite to the pressing protrusion is greater than that of the remaining part.

[0036] In order to have better pressing effect, only the two sides or only the two ends of the hemostatic cotton block are fixedly connected with the hemostatic patch body, when the pressing protrusion and the hemostatic cotton block are both fixed, pressing is only performed on the end part opposite to the pressing protrusion, and when the above-mentioned structure is adopted, the position of the pressing protrusion relative to the hemostatic cotton block can be fine-tuned, that is, the pressing protrusion and the hemostatic cotton block are not fixedly connected, and the flexibility of the material itself can be utilized to deviate from the position, thereby being more flexible in use.

[0037] Since the pressing protrusion is in a cylindrical shape, the pressing inclined surface is arranged at the end part of the cylindrical shape, under the double action of the pressing protrusion and the pressing inclined surface during the pasting of the hemostatic patch, the pressing effect is greatly improved. It should be noted that the length of the pressing protrusion should be avoided to be too long, otherwise the hemostatic patch does not have enough adhesive force to be pasted on the human skin. Therefore, by arranging the pressing inclined surface, the pressing force can be improved while avoiding the length of the pressing protrusion to be too long.

[0038] Embodiment Two

[0039] As shown in Figure 3 , Figure 4 , the difference between this embodiment and Embodiment One is that the pressing protrusion is in the shape of a triangular pyramid. In comparison with the cylindrical structure, the pressing surface of the triangular pyramid is larger. When the pressing protrusion is not aligned with the bleeding port, the pressing effect is not ideal when the cylindrical structure is used. However, the triangular pyramid structure can avoid the above situation and make the use of the hemostatic patch more convenient.

[0040] Embodiment Three

[0041] As shown in Figure 5 , Figure 6 , the difference between this embodiment and Embodiment Two is that the pressing protrusion is in the shape of a trapezoid. The trapezoidal structure, especially the isosceles trapezoidal structure, is more convenient to use. The hemostatic patch with the structure of Embodiment Two can only be fixed on the skin with the thinner side of the pressing protrusion first and then pasted on the skin with the other end. However, this embodiment does not have such a limitation and is more convenient to use.

[0042] Embodiment Four

[0043] As shown in Figure 7 , the difference between this embodiment and Embodiment Three is that the surface of the hemostatic cotton block is fixedly connected with a hemostatic cotton net, the length of the hemostatic cotton net is greater than the length of the hemostatic cotton block, and the two ends of the hemostatic cotton net are fixedly connected with the hemostatic patch body.

[0044] By fixing the hemostatic cotton net on the surface of the hemostatic cotton block, the hemostatic effect is improved. At the same time, the hemostatic cotton block is fixed on the hemostatic patch body by the hemostatic cotton net. Thus, when the hemostatic patch is pasted, especially when it is tightened, the displacement of the hemostatic cotton block can be avoided. The pressing position of the pressing protrusion can also be adjusted slightly, so it is not necessary to align it with the bleeding port completely.

[0045] Embodiment Five

[0046] As shown in Figure 8 , the difference between this embodiment and Embodiment Four is that the hemostatic patch body comprises a first body segment, a second body segment, and an elastic segment connected between the first body segment and the second body segment, the pressing protrusion is fixedly arranged on the inner surface of the elastic segment, the two ends of the hemostatic cotton net are fixedly connected with the first body segment and the second body segment respectively, and the adhesive segments are arranged on the first body segment and the second body segment respectively.

[0047] By setting the elastic section in the middle of the hemostatic patch body and fixing the pressing protrusions on the elastic section, when the hemostatic patch is used and finally pasted on the human skin, displacement of the pressing protrusions caused by pulling can be avoided, and the pressing protrusions can not be separated from the wound and cause discomfort to the patient.

[0048] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Various modifications and changes can be made by those skilled in the art based on the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
