Abstract

The article to which this design relates is, for example, a puncture needle for administering a medicinal solution to a subcutaneous port of a central venous catheter. A subcutaneous port is implanted under the skin for the long-term administration of a medicinal solution. This article can be safely handled with the needle retracted after puncture.
