When puncturing, it will lead to the inability to accurately find the center of the punctured septum. In addition, because of the material, the nursing staff cannot observe and evaluate the situation of the infusion port well during puncture; it will affect the success rate of puncture and cannot adapt to clinical operations. Puncture requirements for different models.

At the same time, the fixation technique and range of the fixer are similar to manual operation, and there is still a risk of needle stick injury for the nursing staff during the puncture.
