Chitosan-iodine composite biological medical film and preparation method thereof

A chitosan-iodine composite biological medical film and a preparation method thereof are disclosed. The chitosan-iodine composite biological medical film is formed by compounding a chitosan-iodine polyvinyl-alcohol layer, a polyvinyl alcohol layer, a chitosan polyvinyl-alcohol foam layer and a hydrophilic polyglutamic acid net-shaped gel layer , and the chitosan polyvinyl-alcohol foam layer is compounded between the polyvinyl alcohol layer and the hydrophilic polyglutamic acid net-shaped gel layer . The four layers have different effects: the chitosan-iodine polyvinyl-alcohol layer has the effects of killing bacteria, moisturizing and promoting healing; the polyvinyl alcohol layer has the effects of moisturizing and promoting healing; the chitosan polyvinyl-alcohol foam layer has the effects of dewatering, absorbing seepage and moisturizing; and the hydrophilic polyglutamic acid net-shaped gel layer has the effects of stopping bleeding, adsorbing the wound and converting the adsorbed seepage to the chitosan polyvinyl-alcohol foam layer. According to the chitosan-iodine composite biological medical film, the chitosan-iodine polyvinyl-alcohol layer and the polyvinyl alcohol layer are heated in a microwave mode, so that a polar medium can be rapidly heated, the reaction temperature is rapidly reached, and the reaction time is shortened; and the chitosan polyvinyl-alcohol foam layer is dried by a vacuum freeze-drying method.

Facial mask capable of being quickly gelatinized and preparation and use method thereof

The invention discloses a facial mask capable of being quickly gelatinized as well as a preparation method and a use method of the facial mask, according to the invention, a cross-linked product of high molecular weight hyaluronic acid or salt thereof and ectoin is used as a facial mask matrix, and the facial mask matrix contains functional components. According to the facial mask, the cross-linked high-molecular-weight hyaluronic acid or salt thereof and the ectoin are used as the facial mask matrix, other skin-care functional components are embedded, physical support is not required to be provided by traditional non-woven fabrics and the like, the facial mask matrix is directly prepared from the functional components, the facial mask is a dry paper-like film, the system is stable, and noextra preservative is required to be added. The facial mask is good in flexibility and good in skin fitness, the facial mask can be rapidly converted into gel essence at an application part, the spray use amount is relatively small, and the gelation conversion time of the facial mask is short. In the degradation process, the high-molecular hyaluronic acid maintains the wet environment of the skinand plays a role in physical protection and slow release, the small-molecular ectoin is gradually released and continuously takes effect, and the functional components embedded in the mask matrix aredegraded and released along with the mask, so that multiple skin care effects are achieved.

Fruit tree cultivation irrigation device

PendingCN113826540APrecision irrigation effectImprove the effect of irrigation and water replenishmentRoot feedersGeneral water supply conservationFruit treeWater flow
The invention provides a fruit tree cultivation irrigation device, and relates to the technical field of tree cultivation management. The fruit tree cultivation irrigation device comprises a main body; the interior of the main body is hollow, and a hoop is fixedly arranged on the outer side of the main body in a sleeving mode through a fastening bolt; a sealing insertion rod is vertically inserted into the main body, two net plates are mounted at the top of the main body, the net plates communicate with the interior of the main body, and a clamping bolt is connected to the top of the main body; a rainwater collecting arc plate is connected to the periphery of the top of the body in a surrounding mode; a water supply pipe is connected to the bottom of the body, and a buried insertion pipe is connected with the bottom of the water supply pipe. Water flow is directly irrigated into deep soil through the buried insertion pipe, so that water evaporation of surface soil is avoided, water flow waste is reduced, and the fruit tree irrigation and water supplementing effects are improved. The problems that according to traditional fruit tree water supplementing irrigation, part of water is located in surface soil and is prone to evaporation due to the influence of illumination, the irrigated water is difficult to be completely absorbed by fruit tree roots, and the fruit tree water supplementing irrigation effect is affected are solved.

Application of polyethylene glycol as active component in preparing psoriasis treating drug and drug thereof

The invention relates to an application of polyethylene glycol as an active component in preparing psoriasis treating a drug and the drug thereof. The inventor finds that polyethylene glycol has an obvious treatment effect to psoriasis and can alleviate splenauxea and increase of MDSCs cell populations effectively through tests. The treatment effect of polyethylene glycol is superior to that of afirst-tier drug calcipotriol for clinically treating psoriasis externally according to skin damage area of psoriasis and score of Psoriasis Area and Severity Index (PASI), and polyethylene glycol is free of toxic and side effects, does not lead to skin allergy, is stable and hard to deteriorate, and meanwhile, fixes water molecules through a lot of hydrogen bonds, so that water is kept in keratoderma or corium layer to increase the inventory of skin moisture, enhance the ventilating property of skin to play a moisturizing role, ensure curative effect continuously, and is free of influence to pH value. The pharmaceutical cost is far lower than clinical drugs such as calcipotriol, the economical burden of a patient can be reduced obviously, and the polyethylene glycol has an extremely wide market prospect.
