[0035] Embodiment one

[0036] Please refer to Figures 1-3 . Figure 1 It is a first side view of the pressing tourniquet disclosed by the utility model embodiment. Figure 2 It is a top view of the pressing tourniquet disclosed by the utility model embodiment. Figure 3 It is a second side view of the pressing tourniquet disclosed by the utility model embodiment

[0037] The pressing tourniquet comprises a belt body 1, a pressing block 2 and a hemostatic patch 3.

[0038] The belt body 1 is flat and long strip-shaped, and the top of the two long edges of the belt body is respectively provided with a parallel first bag and a second bag.

[0039] The first bag 4 and the second bag 5 are both sealed long strip-shaped bag structures, and the length is the same as the long edge of the belt body 1.

[0040] The first bag 4 and the second bag 5 are both provided with a long strip-shaped memory stick 6; the long strip-shaped memory stick 6 is made of memory metal material and is flat structure.

[0041] It should be noted that the memory metal material has bistable characteristics, and after a specific plastic deformation, residual stress is generated inside, so that it has two stable forms of flat expansion and curling.

[0042] The pressing block 2 is fixed to the middle of the bottom of the belt body 1; the width of the pressing block 2 is the same as that of the belt body 1.

[0043] The hemostatic patch 3 is a sterile cotton sheet, which is fixedly attached to the middle of the bottom of the pressing block 2; the area of the hemostatic patch 3 is less than or equal to the area of the bottom of the pressing block 2.

[0044] In use, the hemostatic patch 3 is attached to the needle hole position, and then an external force is applied to the belt body 1, so that the long strip-shaped memory stick 6 in it rapidly changes from a flat state to a curled state, thereby tightly wrapping on the arm, providing pressure to the pressing block 2, and pressing the hemostatic patch 3, thereby achieving hemostasis effect.

[0045] Preferably, the belt 1 is made of non-woven fabric to improve air permeability and reduce cost.

[0046] Preferably, the pressing block 2 is made of elastic material to better fit the shape of arms of different types of people and improve comfort.

[0047] Embodiment Two

[0048] The difference between this embodiment and Embodiment One is that the pressing block 2 is fixed to the belt 1 by magic tape, so that the pressing block 2 and the belt 1 can be separated after each use, thereby allowing the belt 1 to be reused and improving economy.

[0049] Embodiment Three

[0050] The difference between this embodiment and Embodiment One is that, as shown in Figure 2 and Figure 3 , the top of the belt 1 is further provided with a plurality of reinforcing pockets 7; the reinforcing pockets 7 are each provided with the long strip-shaped memory stick 6; the reinforcing pockets 7 are arranged between the first pocket 4 and the second pocket 5 in parallel with the first pocket 4.

[0051] It can be seen that the reinforcing pockets 7 provided with the long strip-shaped memory stick 6 can increase the pressure of the pressing block 2 and better achieve the hemostatic effect.

[0052] Embodiment Four

[0053] Please refer to Figure 4 . Figure 4 is a bottom view of the pressing hemostatic bandage according to an embodiment of the utility model.

[0054] The difference between this embodiment and Embodiment One is that the bottom edge of the hemostatic patch 3 is provided with an adhesive tape 31, and the adhesive tape 31 is coated with adhesive tape, which is used to paste the hemostatic patch 3 on the skin surface around the needle hole in a manner similar to an adhesive plaster, to prevent the hemostatic patch 3 from being separated from the skin when the hemostatic bandage rotates and slides.

[0055] Embodiment Five

[0056] Please refer to Figure 5 . Figure 5 is a first side view of another pressing hemostatic bandage according to an embodiment of the utility model.

[0057] The difference between this embodiment and Embodiment One is that, as shown in Figure 5 , the bottom of the pressing block 2 is provided with an arc-shaped groove; and the hemostatic patch 3 is fixed to the surface of the groove, thereby further fitting the shape of the arm.

[0058] Embodiment Six

[0059] The difference between the embodiment and the embodiment one is that, as shown in Figure 1 , Figure 4 and Figure 5 , the bottom of the band 1 is fixed with several anti-skid strips 8 away from the two ends of the pressing block 2; the anti-skid strips 8 are parallel to the narrow edge direction of the band 1; the bottom of the anti-skid strips 8 is provided with several protrusions 81.

[0060] With the anti-skid strips 8, the band 1 can be prevented from rotating and sliding along the arm direction due to external force during use.

[0061] Optionally, the anti-skid strips 8 are made of silica gel material. Since silica gel has the characteristics of skin-friendly and high friction coefficient, the resistance between the band 1 and the skin can be further improved, and the wearing comfort can be improved.

[0062] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims should be included in the present application. Any reference signs in the claims should not be regarded as limiting the claims.

[0063] In addition, it should be understood that although the present specification is described in terms of embodiments, not every embodiment contains only one independent technical solution, and the description of the specification is only for the sake of clarity, and those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that those skilled in the art can understand.
