Description

Technical Field

[0001] The invention relates to the technical field of liquid bag puncturing, in particular to an automatic liquid bag puncturing machine. Background Art

[0002] In the field of medicine and biology, plasma is generally transported and stored in sterile liquid bags. The mouth of the sterile liquid bag needs to be connected to the puncture needle assembly. In the prior art, the puncture needle assembly is generally inserted into the sterile liquid bag manually. In the process of connecting the puncture needle assembly, due to the good toughness of the plasma bag puncture braid, the needle needs a lot of force to penetrate at the beginning. Once penetrated, the needle will move forward quickly. Since the puncture needle has a bevel, lateral force will be generated during the forward movement, or due to the poor control of the puncture angle, the needle will be deviated and pierce the plasma bag, stabbing the operator's fingers.
