The air inlet valve 23 is arranged in the styptic seat. The air inlet valve 23 is used to connect to an external air source. A convex strip 11 is provided on the outside of the tourniquet 1. The tightening piece 3 is arranged on one side of the tourniquet 1. end, and the other end of the tourniquet 1 passes through the tightening piece 3, which is used to tighten the tourniquet 1; the tightening piece 3 includes a fixing seat 31 and a guide wheel component, and the guide wheel component is arranged in the fixing seat 31; the guide wheel component includes a first extrusion guide wheel 32 and a second extrusion guide wheel 33 arranged on the left and right, the inner sides of the first extrusion guide wheel 32 and the second extrusion guide wheel 33 are both against the convex strip 11, and the lower end surfaces of the first extrusion guide wheel 32 and the second extrusion guide wheel 33 are in contact with the tourniquet 1.

[0019] By providing a tightening piece 3 and utilizing the tightening piece 3 to tighten the tourniquet 1, the hemostatic device can be quickly fixed to the hemostatic site of the human body, thereby achieving convenient and rapid hemostasis; after the hemostatic device is fixed, the tourniquet 1 is pressurized by inflating the compression airbag 22, thereby achieving the effect of compression hemostasis; the provision of the air inlet valve 23 allows the hemostatic device to be connected to an external inflation device, thereby facilitating the inflation of the compression airbag 22.

[0020] By setting a convex strip 11 on the tourniquet 1, the cross section of the convex strip 11 is T-shaped, and the first extrusion guide wheel 32 and the second extrusion guide wheel 33 of the tightening member 3 are respectively in contact with the two sides of the convex strip 11, the upper edge of the convex strip can contact the upper surface of the first extrusion guide wheel 32 and the second extrusion guide wheel 33, and the other end of the tourniquet 1 can be relatively moved by the rotation of the first extrusion guide wheel 32 or the second extrusion guide wheel 33, so as to realize the tightening or loosening of the tourniquet 1, so that the tourniquet 1 can be more tightly tightened on the bleeding part of the human body and avoid the operation of hemostasis. The tourniquet 1 is made of elastic material, which makes the hemostatic device more comfortable and fits the skin.

[0021] Preferably, the hemostatic block 2 further comprises a pressing film 24, which is arranged at the bottom of the hemostatic seat, the airbag 22 is in contact with one surface of the pressing film 24, and the other surface of the pressing film 24 is used to be in contact with human skin.

[0022] In this embodiment, the hemostatic block 2 includes a hemostatic seat, an air bag 22 and a pressing film 24. The pressing film 24 is arranged at the bottom of the hemostatic seat. Since the air bag 22 is confined in the hemostatic seat and the pressing film 24 is located at the bottom of the hemostatic seat, when the air bag 22 is inflated, the air bag 22 expands and exerts pressure on the human skin through the pressing film 24, thereby realizing the principle of compression hemostasis to compress the bleeding site. The pressing film 24 is arranged at the bottom of the hemostatic seat to fit with the human skin. Since the pressing film 24 is made of a flexible or elastic material, the patient's comfort in contact is improved and the fitting effect is better.

[0025] The air inlet end of the pneumatic motor 34 is connected to the output end of the air inlet valve 23 through the vent pipe 26. When the air source is connected and the air inlet valve 23 is opened, the compressed gas provided by the external air source can enter the pneumatic motor 34 through the vent pipe 26 to drive the rotating shaft end of the pneumatic motor 34 to rotate, thereby driving the first extrusion guide wheel 32 to rotate, so that the first extrusion guide wheel 32 and the second extrusion guide wheel 33 jointly drive the other end of the tourniquet 1 to tighten or loosen, thereby adjusting the tightening degree of the tourniquet 1, achieving an automatic fixing effect of the tourniquet 1, and making it more convenient to use.

[0026] Furthermore, the tightening member 3 further includes a speed regulating valve 35, which is disposed in the hemostatic seat, the input end of the speed regulating valve 35 being connected to the output end of the air inlet valve 23, and the output end of the speed regulating valve 35 being connected to the air inlet end of the pneumatic motor 34 through the vent pipe 26. The speed regulating valve 35 is provided to control the amount of air entering the air inlet end of the pneumatic motor 34, thereby preventing the pneumatic motor 34 from rotating too fast and causing harm to the human body, thereby ensuring safe use.

[0027] Preferably, the outer side of the vent tube 26 is fixed to one side of the tourniquet 1. The specific fixing method is to stick the vent tube 26 to one side of the tourniquet 1; or to set a sleeve on one side of the tourniquet 1, the sleeve is integrally formed with the tourniquet 1, and the vent tube 26 is placed in the sleeve. In this way, the vent tube 26 is fixed and protected.
