This utility model discloses a metering and spraying device for chlorhexidine acetate solution. The metering spraying mechanism includes a cavity located on one side of the inner wall of the housing. A first connecting rod is rotatably connected to one side of the cavity. Both ends of the outer wall of the first connecting rod are fixedly connected to rings. Two fixed seats are fixedly connected to the top of each ring. A first connecting rod is rotatably connected to one side of each of the two fixed seats. A second connecting rod is rotatably connected to the other side of the cavity. A cam is fixedly connected to the middle of the outer wall of the second connecting rod. In this utility model, when spraying chlorhexidine acetate solution, the metering cavity is first filled with chlorhexidine acetate solution. When the pressing rod is pressed, the pressure generated by the push plate will squeeze out the chlorhexidine acetate solution inside. Then, it will be re-fed through the feeding mechanism, so that the same amount of chlorhexidine acetate solution will be sprayed out each time, thereby achieving the purpose of metering and spraying, thus improving the efficiency of using chlorhexidine acetate solution.

This invention discloses a long-acting antipruritic and antibacterial topical skin preparation, comprising N-ethyl-γ-L-glutamine, 1-1-palmitoyl-2-oleoyl-sn-glycerol-3-phosphate-N-(L-γ-glutamyl-N-ethyl)-ethanolamine (POPE-N-Et-Gln-α), chlorhexidine acetate, and saffron extract as active ingredients, formulated into a hydrogel or cream with a pharmaceutically acceptable matrix. POPE-N-Et-Gln-α provides rapid transdermal action, while N-ethyl-γ-L-glutamine offers sustained-release and long-lasting effects; saffron extract provides anti-inflammatory and antioxidant effects, and chlorhexidine acetate provides antibacterial and antifungal effects. This invention is hormone-free and non-addictive, achieving both rapid and long-lasting antipruritic effects, and is suitable for eczema, urticaria, dry skin, neurodermatitis, psoriasis, microbial infections, and skin itching caused by insect bites.

The invention discloses a composition of a medical catheter lubricating hydrophilic coating and a preparation method of the composition, belongs to the technical field of medical materials, and aims to solve the problems of excessive swelling, poor combination stability, short service time, low cost and the like caused by uniform water absorption of a coating formed by curing a medical catheter hydrophilic lubricating coating composition in the prior art. In order to overcome the defects that an existing improvement scheme depends on a complex process, is high in cost and is easy to layer, the invention relates to the technical field of medical instruments, and comprises the following components in percentage by mass: 7-10% of polyvinylpyrrolidone; 1.5 to 2.5 percent of polyethylene glycol diacrylate; 0.8 to 1.2 percent of a silane coupling agent KH-570; the content of the medical grade 2-hydroxy-4-methoxyacetophenone is 0.1 to 0.2 percent; 62-68% of absolute ethyl alcohol; 14 to 18% of deionized water; 0.1 to 0.3 percent of chlorhexidine acetate; and 0.2 to 0.5 percent of citric acid. The composition has the property of spontaneously forming a gradient cross-linked structure, the gradient water absorption characteristic can be achieved under the conditions of conventional coating and single-condition curing, extra precise process control is not needed, the industrialization difficulty and cost are reduced, and meanwhile the problem that the binding force between multiple coatings is poor is solved.
