Description
Technical field
The present invention relates to the field of medical instrument technology, specifically a kind of injection device.
Background technique
Bleeding, asphyxia and pressure pneumothorax are the big invertibity causes of death in battlefield three, and wherein bleeding is to influence fight to subtract
The most important factor of member's quantity, necessary and exact hemostasis have extension sick and wounded's life and preservation combat effectiveness of the troops important
Effect.
Hemostasis device is common a kind of survival kit under field environment, and having in field operation medical rescue and rescue can not
The effect of substitution.Hemostasis device used in existing field first aid technology only utilizes a kind of hemostatic material of state, example mostly
Such as stopped blooding by neat liquid or pure powder material, hemostasis flexibility it is smaller, the condition of the injury of some conditions can not be accomplished and
When and exact hemostasis.Pulvis is difficult to and fills out completely for relatively narrow shell hole wound and Hemorrhage in Deep since mobility is poor
Plug, and mostly white powder, are difficult to judge deep hemostasis effect after use；Gel preparation is difficult to fastly extensive bleeding of skin
Speed coating, extends the bleeding time, influences the rescue and treatment of the wounded.Since under condition of battlefield, wounded's condition of the injury is complicated various, homogenous material
Hemostasis device be difficult to handle all problems, therefore, a variety of hemostatic materials to often be used for the different conditions of the injury, this causes
It is very complicated when being handled under battlefield surroundings, it will cause the increase of wounded's amount of bleeding, extend the bleeding time, the rescue for the sick and wounded
Increase certain difficulty.
Application No. is " 201120423090.7 ", Authorization Notice No. be " 202314714 U of CN ", entitled " one kind is included
