[0024] Refer to Figures 1-4 , an inflatable emergency hemostatic belt, including an airbag body 1, a lower valve body seat 2 is arranged on one side of the outside of the airbag body 1, an upper valve body seat 4 is arranged above the lower valve body seat 2, and a valve body 3 is arranged above the upper valve body seat 4. Intake assemblies 7 are symmetrically arranged at both ends on one side of the valve body 3, and a button assembly 6 is arranged between the two intake assemblies 7 on one side of the valve body 3;

[0025] Auxiliary intake assemblies 5 are symmetrically arranged at both ends on the other side of the valve body 3, and an air release valve body assembly 8 is arranged inside the other side of the valve body 3 and between the two auxiliary intake assemblies 5.

[0026] Moreover, the button assembly 6 includes a button body. The button body is located outside the valve body 3. A push rod is installed on one side of the button body, and a push extension convex block is installed on one side of the push rod.

[0027] Moreover, a first spring is sleeved outside the push rod. One side of the first spring is connected to the push extension convex block, and the other side of the first spring is connected to the inside of the valve body 3. A button through-hole is opened at the position of the button body inside the valve body 3.

[0028] At the same time, the intake assembly 7 includes a one-way intake valve. A second spring is installed on one side of the one-way intake valve, and an intake through-hole 31 is opened at the position of the one-way intake valve inside the valve body 3.

[0029] At the same time, the auxiliary intake assembly 5 includes a push rod and a pull ring 51. The push rod is located inside the valve body 3, and a third spring is sleeved on the outer wall of the push rod. The other side of the third spring is connected to the valve body 3.

[0030] Moreover, the pull ring 51 is located outside the valve body 3, and one side of the pull ring 51 extends into the valve body 3 and is connected to the push rod. A pull ring through-hole is opened at the position of the pull ring 51 inside the valve body 3.

[0031] Furthermore, the air release valve body assembly 8 includes an air release valve body 81. A groove is opened on one side of the air release valve body 81 close to the button assembly 6. A steel ball is arranged in the groove. One side of the steel ball is connected to a fixed rod. A fourth spring is sleeved on the outer wall of the fixed rod. The other side of the fourth spring is connected to the groove.

[0032] Furthermore, a connecting rod is installed on one side of the steel ball, and a limiting ring is installed on one side of the connecting rod. A clamping groove is provided in the air release valve body 81 at the position of the limiting ring. A sliding cavity is provided in the air release valve body 81 between the clamping groove and the groove. The diameter of the sliding cavity is larger than the diameter of the connecting rod, and an air release through hole is provided in the valve body 3 at the position of the air release valve body assembly 8.

[0033] It should be noted that two air inlet holes are equidistantly provided at the bottom inside the valve body 3.

[0035] And when there is too much gas in the airbag body 1, the button assembly 6 is pressed. The top protrusion of the button assembly 6 presses the steel ball, and the steel ball drives the limiting ring away from the clamping groove, so that the air in the valve body 3 can be discharged outward, reducing the gas in the airbag body 1. When no air release treatment is required, the button body is released, and the button body is reset under the action of the first spring, and the steel ball is reset under the action of the fourth spring. After the steel ball is reset, its limiting ring is still located in the clamping groove.

[0036] In the present utility model, the inflation tool is externally connected to the air inlet assembly 7 for inflation. During the inflation process, the pull ring 51 is continuously pulled, so that the air entering the valve body 3 can quickly enter the airbag body 1, accelerating the rate of air entering the airbag body 1. And when there is too much gas in the airbag body 1, the button assembly 6 is pressed. The top protrusion of the button assembly 6 presses the steel ball, and the steel ball drives the limiting ring away from the clamping groove, so that the air in the valve body 3 can be discharged outward, reducing the gas in the airbag body 1.
