Problems solved by technology

[0004] In the existing technology of dispensing medicine with prefilled syringes, there is a very large risk during use. Repeated punctures will cause the cork to fall off, resulting in particles in the liquid medicine; in addition, repeated punctures and replacement of the dispenser will increase the crossover risk of contamination

Abstract

The invention discloses a prefilled injector for medicine dissolution and a dispensing device. The prefilled injector comprises a push rod, a piston, a needle tube and a protective cap, wherein the needle tube is provided with a medicine dissolution joint, the medicine dissolution joint is in matched connection with an external cone joint of a prefilled injector for injection, and the protective cap is in sealed connection to an opening of the medicine dissolution joint. During medicine dispensing, the protective cap of the prefilled injector for the medicine dissolution and a protective cap of the prefilled injector for injection are taken off, then, the medicine dissolution joint is directly in matched connection with the external cone joint of the prefilled injector for injection, pushrods of the two injectors are pushed repeatedly for medicine dispensing, after medicines are sufficiently dissolved, the prefilled injector for medicine dissolution is directly taken down, finally, the needle is mounted at the external cone joint of the prefilled injector for injection for injection. The scheme simplifies the dispensing process, the workload of a medical worker is reduced, and puncture scrap falling and cross pollution can be avoided. The invention also discloses the prefilled injector for injection and the dispensing device for the prefilled injector for medicine dissolution.

Description

Technical field [0001] The invention relates to the technical field of medicine packaging, in particular to a prefilled syringe for dissolving medicine and a medicine dispenser. Background technique [0002] Pre-filled syringes have both functions of storing medicines and ordinary injections, bringing many advantages to pharmaceutical companies and clinical use. With the development of prefilled syringe technology, prefilled syringes have become the main packaging method for high-end drugs such as biological agents and chemical drugs due to their convenience and excellent safety. [0003] For drugs that need to be dissolved or formulated before clinical injection, dispensing is a very important process. The existing dispensing process is generally that the powder or freeze-dried powder type medicine is packed in a vial, and the solvent for dissolving the medicine is packed in a prefilled syringe. When dissolving, install the dispenser or dissolving needle on the prefilled syringe...
