The invention provides a disposable nasal cleaning drug delivery device, which comprises a conical body, which is hollow inside and has an open top end, and at least one notch guiding groove is provided on the lower end part of the side wall; At the opening, the other end protrudes from the bottom end of the conical body and is provided with a syringe interface; the spray administration conduit, one end is installed at the center of the top opening of the conical body, and the other end protrudes from the bottom end of the conical body and is provided with a spray Bootstrap interface. In the rescue scene such as disaster, war-wound first aid, etc., the device of the invention can safely realize the continuous action of nasal cavity cleaning and nasal administration. Sedative drugs can effectively avoid the impact of foreign bodies such as dust on the surface of the nasal mucosa on the adhesion and absorption of drugs. The drug delivery effect is more reliable, and complex and dangerous steps such as disinfection and venous blood vessels are not required. It is more practical and feasible in out-of-hospital rescue places.

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 discloses a marine biomedical material for repairing skin wounds and a preparation method and application thereof. From many marine biological actives, the preferred marine fish skin collagen, carboxymethyl chitosan, alginate with good biocompatibility, easy processing and degradation, and the platelet-derived growth factor PDGF-BB are scientifically combined and optimized for preparation made. The material has the advantages of high porosity, high swelling ratio, good mechanical properties, controlled release of PDGF-BB, and no cytotoxicity. It can significantly promote cell adhesion, proliferation, migration and angiogenesis, effectively reduce inflammation and reduce scarring. . The biomedical material has a wide range of applications, is easy to use, can prevent bacterial infection without frequent replacement, and is effective in promoting burns, scalds, cuts, traffic injuries, surgical injuries, war injuries, firearm injuries combined with seawater immersion injuries, diabetic ulcers, inflammation The regeneration and repair effect of chronic ulcers, pressure ulcers and chronic refractory wounds is remarkable.

The present invention relates to a large-scale combat aviation materials demand prediction and reserve decision-making method, comprising the following steps: S1, according to the acquired number N of aircraft battle injuries s and the number of aircraft battle damage N k Build a prediction model for the number of available aircraft in combat, and obtain the number of aircraft available during combat N′ Y ; S2. Constructing a combat aviation material demand prediction model, predicting the combat aviation material demand n″ according to the combat aviation material demand prediction model; S3, constructing a combat aviation material reserve decision model according to the combat aviation material demand n″, The decision-making model determines the reserve limit of combat aviation materials. The invention can ensure the accuracy of the measurement and calculation of the aviation material demand, and enhance the aviation material supply guarantee capability.

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.

A skin knife for war wound treatment according to the present invention comprises a handle and a hollow shaft, and is characterized in that: a first blade seat cooperates with the left part of the hollow shaft, a second blade seat cooperates with the The right part cooperates, and the two ends of a blade supporting plate are matched with the first blade seat and the second blade seat respectively, and a blade is overlapped on the top of the blade supporting plate and positioned and matched with it, and a blade pressing plate is matched with the hollow The middle part of the shaft fits and overlaps the blade to lock the blade on the blade holder; it also includes a first eccentric knob sleeve and a second eccentric knob sleeve fitted on the hollow shaft, and a rolling shaft, One end of the rolling shaft passes through the other end of the connecting plate and is mated with the second nut, and one side of the rolling shaft corresponds to the cutting edge of the blade. The inclination angle of the blade of the present invention can be adjusted as required, and the thickness of cut skin can be effectively controlled; the blade is easy and quick to install and disassemble, and meets the requirements of war wound treatment.
