The invention relates to the field of medical devices, in particular to an intelligent automatic war injury splanchnocoel drainage tube. The tube comprises a drainage tube part, a sleeve cover, a subcutaneous fixing component and an epidermal fixing component, wherein the front end of the drainage tube part is sleeved with the sleeve cover; an external wall of the drainage tube is sequentially sleeved with a first fixing ring, a first movable ring, a second fixing ring and a second movable ring from the top down; the first fixing ring and the second fixing ring are fixed on the external wall of the drainage tube part; the first movable ring and the second movable ring can slide up and down on the external wall of the drainage tube part; the first fixing ring, the first movable ring and a spring jointly form the epidermal fixing component; the second fixing ring, the second movable ring, linkage components and a movable clamp ring jointly form the subcutaneous fixing component; the surfaces of the drainage tube part, the subcutaneous fixing component and the epidermal fixing component are covered with biogel; the surface of the biogel is covered with a film; and the biogel wrapped with the film is arranged in a tube cavity of the sleeve cover. The tube has the advantages of simplicity in operation, quickness in use and strong applicability.

The invention provides a method for preparing bleeding stopping oxidized celluloses in ramie oxidation degumming procedures. The method includes smashing raw ramie to obtain short fibers and soaking the short fibers to sufficiently moisten the short fibers and allow the short fibers to sufficiently swell; mixing the pretreated raw ramie short fibers and degumming solution with one another to obtain mixtures, heating the mixtures, then preserving heat, sufficiently removing colloid in the raw ramie by the aid of oxidability of specific oxidizing agents and simultaneously oxidizing celluloses with active hydroxyl to obtain oxidized celluloses with a large quantity of carboxyl; soaking oxidized and treated fibers by the aid of organic solvent aqueous solution and removing the unreacted oxidizing agents; separating the oxidized celluloses from water and carrying out drying treatment on the oxidized celluloses to ultimately obtain the powdery bleeding stopping oxidized celluloses. The method has the advantages that processes are simple, the original two working procedures are combined into a single working procedure, accordingly, the total reaction time can be shortened, medicines and the cost can be saved, and the efficiency can be greatly improved; the bleeding stopping oxidized celluloses which are products prepared by the aid of the method are high in bleeding stopping speed and bleeding stopping efficiency and can be widely applied to quickly stopping bleeding under conditions of war wound, trauma and the like, and stable effects can be realized.
