However, this method is mostly suitable for the bleeding of small arteries, veins or capillaries, and cannot be used for large wounds, blood vessels, deep bleeding, etc.
The wounded have a high incidence of casualties within one hour after the injury, but due to conditions and equipment limitations, they can only be sent to the hospital for definitive hemostasis. However, a considerable number of wounded suffer from shock and death due to uncontrollable bleeding during the transfer

Abstract
The invention discloses a composite hemostatic syringe, and relates to the field of medical apparatuses. The composite hemostatic syringe comprises an outer drum and an inner drum, wherein an outer drum base is arranged at the back end of the outer drum and an outer front cover is connected to the front end of the outer drum; a crack is formed in the outer front cover; an outer piston is arranged in the outer drum and an outer fastener is fixedly arranged inside the outer piston; an inner cuff is connected to the back end of the inner drum; an inner front cover is connected to the front end of the inner drum; a through hole is formed in the inner front cover; a first hemostatic substance is arranged between the inner drum and the outer drum; an inner piston and a second hemostatic substance are arranged in the inner drum; an inner fastener is fixedly arranged in the inner piston; a hollow core rod is penetrated in the inner drum; a core rod is penetrated in the hollow core rod; one end of the core rod is connected to a handle; the core rod and the outer piston are clamped by virtue of the outer fastener as the core rod is pulled out; the inner cuff and the outer drum are clamped by virtue of a drum fastener as the inner drum extends out of the interior of the outer drum; and the hollow core rod and the inner piston are clamped by virtue of the inner fastener as the hollow core rod is pulled out. With the application of the composite hemostatic syringe provided by the invention, internal hemorrhage can be controlled.
Description
technical field [0001] The invention relates to the field of medical instruments, in particular to a hemostatic device. Background technique [0002] People sometimes suffer from wounds caused by steel bars, knife stabs, or earthquakes, etc., causing trauma to joint junctions, chest, abdomen, and deep tissues, resulting in massive bleeding, or internal blood vessel rupture and bleeding despite trauma. Routine hemostasis can only be used for superficial first aid. Usually, a tourniquet is used to stop bleeding, or gauze, cotton, towel, clothes, etc. are folded into pads of corresponding size, placed on the surface of the wound, and then tightly wrapped with bandages, triangular towels, etc. to stop bleeding . However, this method is mostly suitable for bleeding from small arteries, veins or capillaries, and cannot be used for large wounds, blood vessels, and deep bleeding. The wounded had a high incidence of casualties within one hour after the injury, but due to conditions...
