[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1-3 As shown, a hemostatic device with adjustable tightness includes a hemostatic seat 1 and two wristbands 2 that can be glued together to form a tourniquet. The two wristbands 2 are respectively fixedly connected to both sides of the hemostatic seat 1. An air bladder 4 is embedded in the surface of the hemostatic seat 1. An inflation component 5 is provided on the side of the hemostatic seat 1 away from the air bladder 4. The air guide end of the inflation component 5 is connected to the air bladder 4 to adjust the expansion degree of the air bladder, thereby adjusting the pressure applied by the hemostatic seat 1.

[0023] Among them, the hemostatic seat 1 located around the airbag 4 is surrounded by an annular airbag 3. One end of the annular airbag 3 is embedded in the hemostatic seat 1 and communicates with the airbag 4 to compress the skin around the airbag 4 and assist in hemostasis.

[0024] This device adjusts the pressure of the tourniquet on the bleeding point by inflating and deflating the air bladder through the inflation component. During the adjustment process, the air bladder can always move directly in front of the hemostatic cotton ball without causing the cotton ball to be pulled or moved. There is no need to loosen the entire tourniquet during the adjustment process, making the operation simple and convenient.

[0025] At the same time, the circular airbag squeezes the skin around the bleeding point, slowing down the blood flow around the bleeding point. The circular airbag and the airbag can inflate synchronously. When the blood flow around the bleeding point is slow, the inflated airbag can support the hemostatic cotton ball and press it to block the bleeding point. Under the dual action, rapid hemostasis is achieved and the hemostatic effect is improved.

[0026] The two wristbands 2 can be connected by adhesive tabs or buckles.

[0027] Specifically, such as Figures 1-2As shown, the inflation assembly 5 comprises a balloon 51 and a gas guide pipe 52, the balloon 51 is connected with an air inlet pipe 53, the end of the balloon 51 away from the air inlet pipe 53 is communicated with the gas guide pipe 52, and the end of the gas guide pipe 52 away from the balloon 51 is communicated with the air bag 4;

[0028] The gas guide pipe 52 between the balloon 51 and the hemostat base 1 is provided with an air outlet pipe 54, and the air outlet end of the air outlet pipe 54 is provided with a pull-out pipe plug 55.

[0029] In order to avoid the gas in the gas guide pipe 52 flowing back to the balloon 51, because once the gas flows back, the inflation degree of the entire air bag 4 and the annular air bag 3 will be smaller, therefore, a corresponding anti-backflow assembly needs to be arranged in the gas guide pipe.

[0030] The inner cavity of the gas guide pipe 52 between the air outlet pipe 54 and the balloon 51 is provided with a one-way valve.

[0031] Specifically, as shown in the figure, Figures 1-3 The air bag 4 is arranged in a spherical shape, so that the air bag 4 can be directly pressed against the bleeding point.

[0032] Since the annular air bag 3 surrounds the circumferential side of the air bag 4, and the air bag 4 can be inflated into the annular air bag 3, and the annular air bag 3 needs to be uniformly forced when it is inflated and pressed, therefore, the speed and amount of air inflow of each part of the annular air bag 3 need to be ensured to be the same when it is inflated.

[0033] Specifically, as shown in the figure, Figures 1-3 The equal-interval gas pipes 6 at the same height of the air bag 4 are arranged, and the end of each gas pipe 6 away from the air bag 4 is communicated with the annular air bag 3.

[0034] Since the air bag 4 in a spherical shape has the same pressure at the same height, therefore, each equal-interval gas pipe 6 can equally and at the same speed transport the gas in the air bag 4.

[0035] The above embodiments are only exemplary embodiments of the present application, and are not used to limit the present application, the protection scope of the present application is defined by the claims. Those skilled in the art can make various modifications or equivalent replacements to the present application within the spirit and protection scope of the present application, and such modifications or equivalent replacements shall also be considered to fall within the protection scope of the present application.
