Disposable fully enclosed filtration drug dissolving device

Abstract

The invention belongs to the medical product technical field, and specifically refers to a disposable fully enclosed filtration drug dissolving device; in clinical applications, an injector is normally used for drug adding operation in venous infusion; injector piston pollution in drug adding, outer air particle and microbial pollution of a needle frequently piercing drug bottle and sucking soup, and unfiltered soup directly added in the liquid bottle can all increase drug pollution possibility. The disposable fully enclosed filtration drug dissolving device comprises a drug dissolve needle A, a drug dissolve pot, a filter, and a drug dissolve needle B; the drug dissolve needle A is connected with the drug bottle, then connected with a drug dissolve pot through a soft pipe, and connected with a solvent bottle through the soft pipe filter and the drug dissolve needle B in sequence. When drug adding is completed, one end, connected with the drug dissolve needle A, of the drug dissolve pot is folded, thus extruding the drug dissolve pot to form positive pressure, and the drug dissolve pot rebounds to form negative pressure, so the liquid enters the drug dissolve pot; one end, connected with the drug dissolve needle B, of the drug dissolve pot is folded, so the liquid in the drug dissolve pot can be pushed to enter the drug bottle; after dissolving process, the soup is added in the solvent bottle in a same method, thus completing the drug adding operations. The drug is filtered, and the whole drug adding process is completed in a sealing state.

Description

1. Technical field [0001] The patent of the present invention relates to a medical device, specifically a disposable fully-sealed filter drug dissolving device. 2. Background technology [0002] In clinical practice, in order to reduce the contamination of drugs during intravenous infusion treatment, fully enclosed infusion is adopted, and the drug dosing operation of intravenous infusion usually uses syringes to add drugs, which is still an open method. Contamination of the syringe plunger during dosing, multiple punctures of the drug bottle by the needle, particles in the outside air when the drug solution is drawn, microbial contamination, and unfiltered drug solution directly added to the liquid bottle, all of which increase the probability of drug contamination . Exposure of the needle to the air, pollution of the rubber stopper after the needle pierces the cork of the medicine bottle and liquid bottle many times, and the contamination of particles and microorganisms i...

Problems solved by technology

[0003] The purpose of the patent of the present invention is to provide a one-time use fully-sealed filter drug dissolving device, which solves the pollution of the syringe piston when the intravenous infusion is added, the needle is exposed to the air, and the needle pierces the medicine bottle and liquid for many times. The pollution of the rubber stopper behind the cork of the bottle, the pollution of particles and microorganisms in the outside air when the liquid medicine is pumped, the pollution of the particles in the liquid bottle without filtering the liquid medicine, etc.
