Among all traumatic injuries, massive bleeding is the most life-threatening, accounting for over 95% of deaths from traumatic injuries. This demonstrates the importance of hemostasis in first aid for traumatic injuries. Timely and effective hemostasis is the key to saving lives.

[0003] There are many types of hemostatic devices available, mainly including the following categories:

[0004] 1. Hemostatic bandages, tourniquets, stirrer-type or pressure-type hemostatic dressings, etc., which are mainly used to stop bleeding in the limbs and are basically ineffective in other parts of the body;

[0005] 2. Hemostatic powder, mostly suitable for small blood vessel bleeding and closed internal bleeding;

[0006] 3. Hemostatic forceps, mostly used in professional surgical operations;

[0007] 4. Hemostatic drugs, mostly used for autologous hemolytic diseases and coagulation disorders.

[0008] The applicant has discovered that the prior art has at least the following technical problems:

[0009] Although there are many types of hemostatic devices currently available, the hemostatic sites or indications of these devices are relatively single. In particular, bleeding at the junction of sites is a global problem in hemostasis for emergency treatment of traumatic injuries. The hemostatic devices and drugs used also have defects to varying degrees, and after hemostasis, the tissues below the hemostatic site completely lose blood supply.

[0010] Therefore, there is an urgent need for an emergency airbag hemostatic device and a hemostatic pack to solve the above technical problems. Utility Model Content

[0088] The airbags of the blunt needle hemostatic airbag 1 , the sharp needle hemostatic airbag 2 and the hemostatic bridge airbag 3 can all be inflated by the inflation gas component 4 to apply pressure to the damaged tissue in the victim's body to stop bleeding.

[0089] This first-aid airbag hemostatic pack includes three hemostatic devices: a blunt needle hemostatic airbag 1, a sharp needle hemostatic airbag 2, and a hemostatic bridge bag 3. The pack is compact, lightweight, and highly portable. Each hemostatic device utilizes an inflatable airbag as a medium, using the body's own skin, bones, muscles, and connective tissue as a carrier. By inflating the airbag, blood vessels are compressed, applying pressure from within the victim's body to stop bleeding. Exhausting the airbag relieves the pressure, thus breaking through the external pressure application method of traditional hemostatic devices. This pack effectively targets the compressed blood vessels, preventing the entire local tissue or organ from being compressed, thus avoiding impacting collateral blood vessels. This significantly enhances the body's compensatory capacity and prevents excessive accumulation of metabolic waste. Furthermore, by providing a terminal connected to the airbag and capable of driving the airbag from outside the victim's body to the damaged tissue, use is similar to a puncture during regular infusion, resulting in negligible damage to the body and minimal side effects. The pack is ideal for first aid for traumatic injuries and severe bleeding. This first aid airbag hemostatic pack can be used to stop massive bleeding in all parts of the human body except the intracranial and mediastinal parts of the heart cavity, especially for massive bleeding in the junction parts. It has an outstanding effect on stopping bleeding and can absolutely replace and improve the shortcomings and defects of all existing trauma first aid hemostatic equipment.
