Description

Infusion coupling mechanism

Technical Field

The utility model relates to a medical instrument, in particular to an infusion connection mechanism.

Background

Targeted therapy has become a relatively efficient treatment for diseases such as tumors and cancers, and related treatments such as chemotherapy, nutritional support, aspiration drainage of body fluid, pain management, blood sampling, and repeated infusions or aspiration in clinic are often performed by using an implantable drug delivery device as an infusion device to be left in a human body for a long period of time, wherein the implantable drug delivery device is also called an infusion port.

The existing transfusion port system is of a split type structural design, namely, a transfusion port body and a transfusion tube are separated, the port body and the transfusion tube are easy to fall off in the clinical use process, once the transfusion port body and the transfusion tube fall off, an operator needs to perform incision operation on a patient again, and the patient is easy to be influenced.
