[0015] (III) Beneficial effects
[0016] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0017] 1. For this pressure tourniquet, by setting the inflation structure and the airbag pad, by repeatedly pressing the elastic airbag, the elastic airbag intakes air through the one-way valve and presses the gas into the airbag pad, so that the airbag pad inflates and expands to press on the affected area, thereby enabling pressure hemostasis treatment on the affected area. And by inflating the elastic airbag, the inflation degree of the airbag pad can be adjusted, so as to facilitate the adjustment of the pressure degree. Moreover, the airbag pad has deformability after inflation, which can avoid over-compressing the swollen affected area and causing harm.
[0018] 2. For this pressure tourniquet, by setting the overpressure elastic structure and the exhaust port, when the affected area is severely swollen, the airbag pad is squeezed and deformed, and the gas inside the airbag pad enters the housing through the pipeline, causing the air pressure to control the piston to compress the spring and move, so that the gas flows into the housing, which can avoid the problem that the gas inside the airbag pad cannot be discharged and cause over-compression of the affected area. Moreover, when the swelling is severe, the piston moves to expose the exhaust port, and at this time the gas exhausts from the exhaust port, thereby greatly reducing the harm to the affected area.
[0019] 3. This pressure hemostatic bandage adjusts the movement of the push spring of the adjusting plate through the elastic adjustment structure, causing the piston to move and fit against the side wall of the housing. At this time, by continuing to apply pressure to the spring, the spring accumulates elastic force, so that the degree of compression of the spring force increases compared to the original state, and thus the pressure state can be adjusted according to the condition of the affected area.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0025] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments.
[0026] As Figures 1-4As shown in the figure, the present utility model provides a technical solution: a pressure hemostatic bandage, which includes a pressing piece 1. Both sides of the pressing piece 1 are fixedly connected with a covering structure 2. The covering structure 2 includes a cloth strip 21. One end of the cloth strip 21 is fixedly connected to the pressing piece 1, and the other end of the cloth strip 21 is fixedly connected with a magic tape 22. By wrapping the cloth strip 21 around the patient's body, since one of the two magic tapes 22 is a fuzzy surface and the other is a prickly surface, the two magic tapes 22 are adhered to each other to fix the position of the pressing piece 1. The bottom of the pressing piece 1 is fixedly connected with an airbag pad 9. An exhaust valve 4 is provided above the airbag pad 9. The internal gas of the airbag pad 9 can be discharged by operating the exhaust valve 4, and the exhaust valve 4 penetrates through the pressing piece 1. One end of the airbag pad 9 penetrates upward through the pressing piece 1 and is communicated with an inflation structure 3. The end of the airbag pad 9 connected to the elastic airbag 31 is a one-way tube, and the one-way tube can maintain one-way air intake to prevent gas from flowing back into the elastic airbag 31. The inflation structure 3 includes an elastic airbag 31. The elastic airbag 31 is fixedly connected to the top of the pressing piece 1. The bottom of the elastic airbag 31 is communicated with the airbag pad 9. By repeatedly pressing the elastic airbag 31, the elastic airbag 31 intakes air through a one-way valve 32 and presses the gas into the airbag pad 9, so that the airbag pad 9 inflates and expands and can press on the affected area, thereby enabling pressure hemostasis treatment on the affected area. Moreover, by inflating the elastic airbag 31, the degree of inflation of the airbag pad 9 can be adjusted, so as to facilitate the adjustment of the pressure level. And the airbag pad 9 has deformability after inflation, thus avoiding excessive compression of the swollen affected area and causing harm;
[0027] A one-way valve 32 is provided at the top of the elastic airbag 31. The one-way valve 32 can maintain one-way air intake, enabling gas to enter the elastic airbag 31 unidirectionally and preventing gas from being discharged. The inside of the elastic airbag 31 is filled with a spring 81 piece. The spring 81 piece can not only play a role in supporting and shaping the elastic airbag 31, but also endow the elastic airbag 31 with good elastic recovery, thus facilitating the inflation operation. The inflation structure 3 is fixedly connected to the top of the pressing piece 1. A housing 10 is fixedly connected above the pressing piece 1. A scale window 7 is provided above the housing 10. Through the scale window 7, it is convenient for personnel to observe the position of the piston 82, and there are scales on the scale window 7, so that the degree of compression adjustment of the spring 81 can be accurately known. One end of the housing 10 is communicated with the airbag pad 9 through a pipeline passing through the pressing piece 1. An overpressure elastic structure 8 is provided inside the housing 10. The overpressure elastic structure 8 includes a piston 82. The piston 82 is arranged in the housing 10. One side of the piston 82 is fixedly connected with a spring 81. When the swelling of the affected area is relatively serious, the airbag pad 9 is squeezed and deformed. The internal gas of the airbag pad 9 enters the housing 10 through the pipeline, causing the air pressure to control the piston 82 to compress the spring 81 and move, so that the gas flows into the housing 10, which can avoid the problem of excessive compression of the affected area caused by the inability to discharge the internal gas of the airbag pad 9. Moreover, when the swelling is relatively serious, the piston 82 moves to expose the exhaust port 5, and at this time the gas is exhausted from the exhaust port 5, thereby greatly reducing the harm to the affected area;
[0028] One end of the overpressure elastic structure 8 is fixedly connected with an elastic adjustment structure 6. The elastic adjustment structure 6 includes a housing 62. The housing 62 can guide the adjustment plate 61 so that the adjustment plate 61 can slide smoothly. The housing 62 is embedded in the housing 10. An adjustment plate 61 is slidably connected inside the housing 62. One side of the adjustment plate 61 is fixedly connected with a spring 81. The adjustment plate 61 is locked in the housing 62 by bolts. By rotating the bolts, the bolts are tightened on the adjustment plate 61, so that the position of the adjustment plate 61 can be locked. The elastic adjustment structure 6 passes through the housing 10. Exhaust ports 5 are provided in the middle of both sides of the housing 10. By pushing the spring 81 to move through the adjustment plate 61, the piston 82 moves to fit against the side wall of the housing 10. At this time, by continuing to apply pressure to the spring 81, the spring 81 accumulates elastic force, so that the compression degree of the spring 81 under force increases compared with the original state, and thus the compression state can be adjusted according to the condition of the affected area.
[0029] The working principle of the present utility model is as follows:
[0030] When applying pressure to stop bleeding on the affected area, the airbag pad 9 is applied to the affected area, and the cloth belt 21 is wound around the patient's body, and then the pressing plate 1 is adhesively fixed through two magic tapes 22. Then, the elastic airbag 31 is reciprocally pressed, so that the elastic airbag 31 intakes air through the one-way valve 32 and presses the gas into the airbag pad 9, so that the airbag pad 9 expands to apply pressure to stop bleeding on the affected area. When the affected area of the patient swells, the airbag pad 9 is squeezed and deformed, and the gas enters the housing 10 through the pipeline, so that the piston 82 is pressed to squeeze the spring 81 to deform, so that the pressure on the affected area is reduced. And when the piston 82 moves to expose the exhaust port 5, the exhaust can be carried out through the exhaust port 5 at this time, avoiding the problem of serious compression caused by excessive swelling of the affected area.

For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.
[0032] The above has made a detailed description of the preferred embodiment of the present patent, but the present patent is not limited to the above embodiment. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the purpose of the present patent.
