[0010] Currently, in the existing technology, although hemostatic devices can achieve the hemostatic function of patient trauma, traditional hemostatic devices do not take into account the changes in the patient's body temperature and environmental temperature. Some injured people may have a drop in body temperature due to massive bleeding when they are sent to the emergency department. When the core body temperature is less than 36°C, the platelet adhesion function decreases, the aggregation ability weakens, the coagulation factor activity decreases, the PT and APTT are prolonged, the fibrinogen synthesis is blocked, and the fibrinolytic activity is enhanced. Studies have shown that a low temperature of 34°C can increase blood loss by 20%. In this case, the traditional hemostatic device reduces the hemostatic effect. Summary of the Invention

[0042] Working principle:
[0043] When performing hemostatic treatment on the wound of the injured person, first place the hemostatic gauze strip 3 close to the constant temperature film bag 2, let the third magic tape 8 and the fourth magic tape stick together to complete the fixation of the hemostatic gauze strip 3, and then fit the hemostatic gauze strip 3 to the wound of the injured person, and fix the inflatable hemostatic airbag 1 and the hemostatic gauze strip 3 to the wound by the first fixing belt 4 and the second fixing belt 6.

[0044] The water temperature is heated to 40-60°C (adjusted according to the patient's body temperature and the ambient temperature) by the heating device in the constant temperature water storage tank 19, and is kept in a constant temperature state by the thermostat and the temperature sensor. The second water valve 24 on the second liquid extraction pipe 22 and the fourth water valve 27 on the fourth liquid extraction pipe 26 are opened, and the second liquid extraction pump 21 is started. The second liquid extraction pump 21 extracts water from the constant temperature water storage tank 19 through the second liquid extraction pipe 22, and the water enters the constant temperature film bag 2 through the fourth liquid extraction pipe 26 to ensure the temperature of the wound. At the same time, the first liquid extraction pump 16 is started, the first water valve 18 on the first liquid extraction pipe 17 is opened, and the water from the constant temperature film bag 2 is extracted through the first liquid extraction pipe 17. Finally, the water enters the constant temperature water storage tank 19, so that the water inside the constant temperature film bag 2 is always in a constant temperature state;
[0045] By continuously squeezing and pressing the airbag 10, the air inside the compressed airbag 10 enters the interior of the inflatable hemostatic airbag 1 through the first air supply pipe 9, causing the inflatable hemostatic airbag 1 to inflate, thereby squeezing the wound of the injured person and allowing the hemostatic gauze strip 3 to fit tightly against the wound. By opening the exhaust valve 15, the air inside the inflatable hemostatic airbag 1 can be discharged through the exhaust pipe 14, thereby changing the pressure of the inflatable hemostatic airbag 1 on the wound.
[0046] In some cases, warm saline gauze is needed for compression hemostasis. The water temperature is heated to 50-60°C (adjusted according to the patient's body temperature and ambient temperature) through the heating device in the saline tank 20. Warm saline gauze of 50-60°C is the best choice for compression hemostasis. This temperature is close to the optimal point of thrombin reaction (about 37°C). It is kept in a constant temperature state by the thermostat and the temperature sensor. The third water valve 25 on the third liquid extraction pipe 23 and the fourth water valve 27 on the fourth liquid extraction pipe 26 are opened, and the second liquid extraction pump 21 is started. The second liquid extraction pump 21 draws warm saline from the saline tank 20 through the third liquid extraction pipe 23, and the warm saline enters the interior of the constant temperature film bag 2 through the fourth liquid extraction pipe 26. At the same time, the solenoid valve 30 is opened, and the warm saline inside the constant temperature film bag 2 flows through the water outlet pipe 29 to the hemostatic gauze strip 3, compressing the wound of the injured person to stop bleeding. The hemostatic gauze strip 3 is replaced according to the water seepage on the hemostatic gauze strip 3.
