Description

Transfusion system

Technical Field

The utility model relates to the field of medical infusion apparatuses, in particular to an infusion apparatus.

Background

Infusion sets are a common medical consumable used for intravenous infusion by establishing a passageway between a vein and a medical fluid. The syringe is generally formed by connecting a bottle stopper puncture outfit (puncture needle), a perfusion tube, a flow rate regulator, a dropping funnel (Murphy dropper) and the like, and is also commonly provided with a perfusion needle (scalp needle). The scalp needle is used for puncturing veins and exhausting air in the infusion set. At present, a plurality of patients use the indwelling intravenous needle clinically, and the indwelling intravenous needle only needs to puncture once during transfusion, repeated needle insertion is not needed, and only the disposable puncture scalp needle attached to the transfusion device can be discarded, so that waste is caused, and unnecessary medical waste treatment cost is generated; in addition, infusion sets with scalp needles also increase the risk of clinical puncture injuries. Thus, it is necessary to design an infusion set that does not carry a scalp needle and that retains the venting function.
