Drug-mixing connector for plastic infusion soft bag

Abstract

The invention discloses a drug-mixing connector, in particular relates to a drug-mixing connector for a plastic infusion soft bag, belonging to the technical field of medical device manufacturing. The drug-mixing connector is characterized in that, during the drug mixing process, when an easy-to-break handle is broken, the infusion soft bag is not damaged, and the broken handle segment of the easy-to-break handle does not drop into a plastic infusion soft bag. The drug-mixing connector comprises the easy-to-break handle, the infusion soft bag and a hard dual connector which is connected with the infusion soft bag and comprises a drug-mixing channel and an infusion channel; the drug-mixing channel is connected with a drug-mixing mouth which comprises a drug-mixing clamping body and a needle cylinder body; the drug-mixing connector further comprises a sealed rubber hose, and the drug-mixing mouth is connected with the drug-mixing channel through the needle cylinder body and the sealed rubber hose; and the easy-to-break handle is sheathed at the tail end of the needle cylinder body in the sealed rubber hose.

Description

technical field [0001] The invention relates to a drug mixing interface, in particular to a drug mixing interface for plastic infusion soft bags, and belongs to the technical field of medical device manufacturing. Background technique [0002] When using the powder injection, freeze-dried powder injection or water injection contained in the vial, it is necessary to draw out the liquid medicine or water for injection in the infusion soft bag and inject it into the vial through the syringe, and repeat the above work until there is enough liquid medicine in the vial Then the vial is shaken repeatedly until the medicament in the bottle is evenly mixed, and then the medicinal liquid in the vial is extracted and injected into the soft infusion bag with a syringe, and so on, until the medicinal liquid in the bottle is exhausted. The above-mentioned drug mixing operation process is time-consuming, laborious, and consumes consumable materials such as syringes, and it is very easy to ...

Problems solved by technology

But this drug mixing interface also has many deficiencies, and its disadvantages mainly contain the following points: the easy-fold handle of the drug-mix interface is located in the infusion soft bag, and when in use, after breaking the easy-break handle, the handle section is extremely It is easy to fall into the soft infusion bag, and at the same time, when the easy-break handle is broken, plastic particles will be produced to pollute the drug solution in the infusion soft bag, and in the process of breaking, due to the toughness of the PP plastic used in the easy-break handle, the breaking force will be reduced. Larger, it is very easy to puncture the soft infusion bag during the breaking operation, making the soft infusion bag unusable

And because the syringe body of this technology is made of polypropylene material, it is difficult to achieve th
