For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this patent according to the specific circumstances.

[0023] Please see Figures 1-3 and Figure 6 As an example, a convenient hemostatic device includes gauze 11 covering the arm 1 and medical tape 12 for fixing the gauze 11; a pressing mechanism 2 for pressing the gauze 11 is provided on the side of the gauze 11, the pressing mechanism 2 includes an outer shell 23, a locking block 24 and an inner rod 25, the cross-sectional shape of the outer shell 23 is arc-shaped, and a sliding cavity is opened inside it, in which the arc-shaped inner rod 25 is slidably connected, the outer shell 23 has a sliding opening on the side near the arm 1, and a sliding block 28 is slidably connected in the sliding opening, the upper end of the sliding block 28 is fixedly connected to the locking block 24, and the locking block 24 is elastically connected to the inner wall of the outer shell 23; there are two inner rods 25, and the two inner rods 25 are symmetrically arranged about the sliding block 28, with the opposite ends of the two inner rods 25 All are elastically connected to the outer shell 23 via a second spring 27. Both ends of the locking block 24 are fixedly connected with hooks. Both ends of the inner rod 25 that are close to each other are provided with slots that engage with the hooks. Magnetic sheets 29 that attract each other are glued to the ends of the two outer shells 23 that are far apart from each other. A first spring sheet 10 is also connected to one side of the outer shell 23 via a telescopic plate 9. The first spring sheet 10 is V-shaped with the opening facing downwards. A sliding groove is also provided on the outer side of the outer shell 23 and the inner rod 25. A vertical rod 3 is slidably connected in the sliding groove. A handle 4 is rotatably connected to the side of the vertical rod 3 that is far away from the outer shell 23. The handle 4 is rotatably connected to the medical tape 12 via a rotating shaft 8. The medical tape 12 is spaced above the gauze 11. A hemostatic mechanism 6 is also provided on the side of the medical tape 12.

[0024] A connecting post 30 is fixedly connected to the side of the rotating shaft 8 near the medical tape 12. A fourth spring piece 31 is fixedly connected to the periphery of the end of the connecting post 30 away from the rotating shaft 8. The plane of the fourth spring piece 31 is inclined to the end face of the rotating shaft 8.

[0025] A pressing roller 7 is also provided above the rotating shaft 8. The pressing roller 7 is rotatably connected to the connecting rod 5 through the second spring piece 13. The pressing roller 7 is located directly above the medical tape 12.

[0026] When the user places gauze 11 on the wound of the injured person's arm 1 and places the pressing mechanism 2 on the arm 1, the inner rod 25 is still inside the outer shell 23. When the sliding block 28 at the lower end of the outer shell 23 comes into contact with the arm 1, the sliding block 28 is squeezed and moves upward, thereby triggering the locking block 24 to move upward, causing the locking hook and the locking slot to move away from each other. Without the restraining force from the locking block 24, the inner rod 25 will be pushed out of the outer shell 23 under the deformation of the second spring 27, so that the two inner rods 25 are connected by the mutually attracting magnetic pieces 29, thereby making The inner rod 25 and the outer shell 23 form a closed loop surrounding the arm 1. At this time, a complete sliding groove is formed at one end. When the user turns the handle 4, the handle 4 rotates around the pressing mechanism 2, which in turn causes the medical tape 12 to wrap the arm 1. Since the side of the pressing mechanism 2 is also connected to the first spring 10 through the telescopic plate 9, and the first spring 10 is located above the gauze 11, when the pressing mechanism 2 is placed on the arm 1, the gauze 11 is pressed tightly. At this time, the user can free up his hand to turn the handle 4, which causes the medical tape 12 to stick the gauze 11 to the arm 1.

[0027] In summary, by using the pressing mechanism 2 to press the first spring 10 against the gauze 11, the user can free up their hand to operate the handle 4, which rotates around the outer side of the outer shell 23 and the inner rod 25. At the same time, the medical tape 12 moves around the gauze 11 and adheres it. This allows the user to calmly and easily stop the bleeding of the injured person's wound without being overwhelmed by too many parts to support, thus improving the ease of use of this design.

[0028] Furthermore, since the first spring piece 10 is elastic, it is inevitable that a large area of ​​gauze 11 needs to be pressed down when pressing the gauze 11 smoothly. At this time, it is not a problem to stick the first spring piece 10 onto the gauze 11 with the medical tape 12 during the bandaging process. Just remove the pressing mechanism 2, thereby driving the first spring piece 10 to slide off the gauze 11. At this time, the medical tape 12 in the space where the first spring piece 10 is removed can still be firmly stuck to the gauze 11, which improves the fault tolerance of this design.

[0029] Furthermore, in order to improve the stability after the medical tape 12 is installed, multiple fourth springs 31 are provided. Through the expansion of the fourth springs 31, the medical tape 12 can be firmly fixed on the rotating shaft 8.

[0030] Furthermore, the design of the second spring 13 and the pressing roller 7 is such that, during use, the volume of the medical tape 12 will become smaller and smaller. Therefore, when the user turns the handle 4, the pressing roller 7 can be driven by pressing the second spring 13 to squeeze the medical tape 12 downward. Within the elastic range allowed by the fourth spring 31, the bonding gap between the medical tape 12 and the gauze 11 is reduced, avoiding the entry of a large amount of dust due to excessively long gaps between the medical tape 12 and the gauze 11, thus preventing the wound from being contaminated by dust.

[0031] Please see Figure 1 , Figure 4 and Figure 5 In a preferred embodiment, the hemostasis mechanism 6 includes an elastic housing 14, an air bladder 15, and an air source cylinder 16. The air bladder 15 is fixedly connected to the inner side of the elastic housing 14, and an air cavity is opened inside the elastic housing 14. The air source cylinder 16 is arranged above the elastic housing 14, and a valve 17 is installed on the air source cylinder 16. The air source cylinder 16 is connected to the air cavity, and the elastic housing 14 is connected to the air bladder 15.

[0032] The elastic shell 14 has a fixing groove in the middle, and a support piece 20 is horizontally installed in the fixing groove. The support piece 20 is elastically connected to the elastic shell 14 by a first spring 21. An elastic band 18 is provided on the outside of the fixing groove. One end of the elastic band 18 is rotatably connected to the elastic shell 14 and a first hook and loop fastener 19 is fixed on the other end. A second hook and loop fastener 22 is fixedly connected to the side of the elastic shell 14 away from the elastic band 18. The second hook and loop fastener 22 is located on the side of the fixing groove. The first hook and loop fastener 19 and the second hook and loop fastener 22 are adhesively fitted together.

[0033] The elastic shell 14 is U-shaped, and the U-shaped elastic shell 14 includes an engaging section and a supporting section. The engaging section is located at the upper end of the supporting section. The engaging section includes a pair of trumpet-shaped engaging side plates, with the small opening of the trumpet facing upward.

[0034] Both of the two engaging side plates have an arc-shaped flap fixedly connected to their upper ends.

[0035] In use, the hemostasis mechanism 6 is used to simulate the function of the most common rubber tourniquet in bandaging. However, the hemostasis mechanism 6 in this design is simple to operate and easy to use compared to the rubber tourniquet, making it more suitable for bandaging novices and also saving time during bandaging.

[0036] Specifically, the elastic shell 14 is fitted onto the arm 1, and the elasticity of the elastic shell 14 itself clamps the injured person's arm, slowing down the flow of blood. Then, by opening the valve 17, the gas inside the valve 17 is introduced into the airbag 15. By inflating the airbag 15, the blood flow in the injured person's arm is further controlled. Then, the elastic band 18 is pulled, and by the limiting of the elastic band 18 in the fixing groove, the injured person's arm is tightened in a closed loop, thereby achieving the purpose of restricting the blood flow of the injured person.

[0037] Furthermore, the shape of the elastic shell 14 and the design of the arc-shaped flap can further improve the convenience of putting the elastic shell 14 on the outside of the arm, thus improving the efficiency of this design.

[0038] The preferred embodiments of this patent have been described in detail above. However, this patent is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this patent.
