Description

A kind of solvent adapter without multiple puncture bottle stopper

technical field

The invention belongs to the technical field of medical devices, and in particular relates to a solvent adapter that avoids multiple puncture bottle stoppers.

Background technique

At present, my country's pharmaceutical industry is developing rapidly, but many hospitals still use the traditional syringe dosing method in clinical practice. When preparing intravenous liquid, the liquid is drawn from the small vial into the syringe, and then added to the solvent bottle. If it is a powder injection, it must be It must be dissolved first, and a syringe must be used in the process of dissolving the powder and dosing. Every time the solvent is drawn, the needle must be pierced into the solvent bottle to repeatedly suck and puncture the stopper, which may cause needle or hand damage. Contamination, especially repeated puncturing of the rubber stopper, is more likely to cause contamination of the medicinal solution and carry insoluble particles such as rubber shavings into the medicinal solution, causing droplets to enter the bloodstream and form thrombus, leading to cardiovascular and cerebrovascular embolism, threatening the life of the patient. At the same time, during the configuration process, if the infusion bag is relatively soft, it is easy to contaminate the infusion port and the operating surface due to contact. The needle often punctures the medical staff during the use process, resulting in medical and nursing exposure, and the used steel needle is difficult to handle. ; Some of the existing liquid dispensing devices solve the problem of contact pollution between the soft infusion bag and the work surface, but less treatment of insoluble particles, and some devices have complex structures, high material requirements, and high prices, making it difficult to mass produce.
