Preferably, the notch is an arc-shaped gap, and the notch is set to be arc-shaped, so that the insertion of the infusion apparatus pipe orifice is more convenient.

Specifically, the blocking piece is made of an elastic material, preferably a polyurethane material with good elasticity.

Specifically, a detachable end cover A is sleeved outside a medicine outlet joint of the infusion bag; a detachable end cover B is sleeved outside the medicine inlet joint of the infusion apparatus, a medicine outlet joint of an infusion bag and the medicine inlet joint of the infusion apparatus are protected through the end cover A and the end cover B before infusion, pollution is avoided, and the end cover A and the end cover B can be removed during infusion; more specifically, end cover A, end cover B are polyvinyl chloride material (PVC), thermoplastic elastomer material (TPE) or latex material.

The utility model has the advantages that:

the utility model provides an infusion set connects through setting up the stifled piece and seals infusion bag's play medicine joint, inserts with the mouth of pipe that supplies the infusion ware through the incision that sets up the slope on the stifled piece, and threaded connection through going out liquid joint and income liquid joint guarantees that infusion in-process transfusion system follows the infusion bag landing.
