[0002] Self-hemostasis has always been a major problem in sudden trauma. The external trauma wound is small but the internal bleeding is large. Deep trauma bleeding that cannot be effectively reached by conventional hemostatic dressings or pressure hemostasis is one of the thorny problems in emergency hemostasis. During the first aid process, the hemostatic agent is quickly delivered to the hemostatic site, which can not only stop bleeding quickly and reduce large-scale blood transfusions, but also reduce hemorrhagic shock injuries and strive for the best rescue time.

[0003] At present, a Chinese invention with the announcement number of CN115721363A discloses a device for introducing hemostatic materials for deep trauma. The invention discloses a device for introducing hemostatic materials for deep trauma, including a tube body, a piston is arranged in the tube body, the piston is gas-sealed with the inner wall of the tube body, a piston positioning column is fixed in the piston, a push rod is inserted in the piston and the piston positioning column, the push rod can move relative to the piston and the piston positioning column, the head of the push rod is located in the tube body, the tail of the push rod is located outside the tube body, a baffle is arranged at the tail of the push rod, the head end of the tube body is detachably connected with a sealing sleeve, the tail of the tube body is provided with a convex piece, a sealed cavity is formed between the tube body, the piston and the sealing sleeve, and the cavity is filled with hemostatic drugs; the head of the push rod is provided with an elastic self-locking head, the piston positioning column is provided with a self-locking chamber, after the push rod is pulled out, the elastic self-locking head is embedded in the self-locking chamber to form self-locking, this invention solves the problems of small drug storage space and large space occupied by the device in the prior art.

[0004] According to the above patent, the existing deep trauma hemostatic material introduction device pulls the push rod so that the elastic self-locking head at its head enters the self-locking chamber in the piston positioning column to form a self-locking state, and the index finger and middle finger are used to hold the convex piece of the tube body, the sealing sleeve at the head of the tube body is removed, the head of the tube body is aimed at the wound, and the baffle at the tail of the push rod is pushed down with the thumb to inject the hemostatic drug in the tube body into the wound. However, when the user pulls the push rod to make the elastic self-locking head enter the self-locking chamber, there is no structure on the surface of the push rod and in the self-locking chamber that can be used to position the elastic self-locking head when the push rod is driven to move into the self-locking chamber, which makes it easy for the user to pull the push rod excessively, so that the elastic self-locking head and the push rod are pulled out of the interior of the tube body, so that the elastic self-locking head cannot be placed in the self-locking chamber, and then cannot be used normally. Therefore, the above patent is improved according to the problems raised. Utility Model Content
