The problem of blood loss is still the most urgent problem to be solved in the current war wound treatment, and according to related data, a large number of cases which can not be controlled account for 90% of death cases.
At present, the tourniquet used in battlefield has the defects of incomplete hemostasis, inconvenient operation, incapability of using by one hand, difficult control and observation of pressure and the like, and is easy to cause serious pain or tissue damage. After the tourniquet which is currently arranged in an army is used, the tissue at the far end is easy to be damaged by ischemia, so that the tissue necrosis is caused, and the amputation and even the life endangering are caused by anaerobic infection. The use of tourniquets on the battlefield is discouraged due to the fear of causing limb necrosis.
From the above, it can be seen that the control of blood loss at the junction of trunk and limbs on the battlefield is still the focus of current research, especially when major arteriovenous trauma in the groin area or armpit is ruptured, and the means that can be taken on the battlefield is extremely limited.
Often the wound surface of a gunshot wound is irregular, especially the wound surface caused by a rifle. If the gunshot injuries at the groin area or the armpit are combined with main arteriovenous rupture bleeding, the existing local pressurization hemostasis or tourniquet bandaging hemostasis mode cannot achieve ideal hemostasis effect.
Therefore, it is desirable to provide a hemostatic device and a syringe for pushing the hemostatic device, which are especially suitable for large-area gunshot wounds, are easy and convenient to operate, can rapidly fill and seal wounds to stop bleeding, can effectively prevent the wound from falling out of the wound during use, are convenient to operate, and prevent wound infection caused by hemostatic operation.

The hemostasis device of this application adopts the design of hemostasis chain, can have the wounded who has received the bullet wound by oneself put into the wound with it fast. After the hemostasis unit absorbs blood or tissue fluid and expands, the wound is closed, and meanwhile, appropriate sealing and fixing are carried out on the surface of the wound, for example, the bandage is simply bound, the surface of the wound is pasted by medical adhesive plaster, and the like, so that the hemostasis effect is achieved.
