Injectable hemostatic sponge device, injector and suite part

Abstract

Disclosed is an injectable hemostatic suite part for sinus tract wounds, duct wounds, and penetrating wounds. The injectable hemostatic suite part comprises an injectable hemostatic sponge device and an injector. The injectable hemostatic sponge device comprises hemostatic sponge blocks and connecting threads, the hemostatic sponge blocks are polyvinyl alcohol-chitosan composite sponges and are in a cylindrical shape, and cross-shaped X-ray developing threads are sewed on the surfaces. The injector comprises an injector push rod, an injector rotary plug, a push rod clamping base, an injector cylinder and an injector cap; the hemostatic sponges for manufacturing the hemostatic sponge blocks are prepared from foaming of polyvinyl alcohol and chitosan, each hemostatic sponge is of a three-layer structure, the middle layer is polyvinyl alcohol, the upper layer and the lower layer are the compound of polyvinyl alcohol and chitosan, and the proportion of chitosan is 3-10%; when storage is conducted, the injector cylinder is filled with the hemostatic sponge device, during use, firstly the injector cap is plucked off, then the injector is placed in the wound, and the injector push rod is driven to make the wound filled with the hemostatic sponge device.

Description

technical field [0001] The invention relates to the field of medical devices, and relates to an injectable hemostatic sponge device, a syringe and a kit, and also relates to a hemostatic sponge and a preparation method thereof. Background technique [0002] First aid and hemostasis is an important part of first aid for war wound bleeding. Research data show that the main cause of war wound death is that 50% of the wounded are bleeding before they are sent to the treatment institution; The most important cause of various complications. Commonly used hemostasis methods are mostly finger pressure hemostasis, dressing, bandage or triangular towel pressurized to stop hemorrhage, autologous compression hemostasis, tourniquet hemostasis, tamponade and so on. Most of the bleeding from war wounds is hole wounds caused by bullets and shrapnel, sinus tract wounds, and similar types of bleeding. For such wounds, gauze filling is generally used to stop bleeding, but there are problems s...

Problems solved by technology

Most of the bleeding from war wounds is hole wounds caused by bullets and shrapnel, sinus tract wounds, and similar types of bleeding. For such wounds, gauze filling is generally used to stop bleeding, but there are long time to stop bleeding, inconvenient application, and adhesions. Disadvantages such as wounds
