[0002] A fully implantable venous access port (IVAP) is a method of intravenous infusion that is completely implanted in the human body. It is a safe and reliable intravenous infusion channel that can safely infuse various hyperosmotic drugs, highly stimulating drugs, etc. into the human body, reducing the pain caused by repeated punctures. A fully implantable infusion port can be left in the human body for a long time and has been accepted by more and more children. A fully implantable infusion port consists of a venous catheter system and a port seat for puncture. A butterfly-shaped non-destructive needle is used to puncture the silicone diaphragm of the port seat to establish an intravenous medication route. After puncture, the butterfly-shaped needle wing and the infusion port base must be properly fixed to ensure the patency of the pipeline.

[0003] Due to the activeness of sick children, improper or loose fixation of the infusion catheter, or other treatment needs (such as bone puncture, lumbar puncture, etc.), the butterfly wing intact needle often falls off the infusion port seat, and the infusion catheter shifts, resulting in the need to replace the butterfly wing intact needle or even re-set the infusion port. Even if it is not completely dislocated, fluid extravasation is prone to occur. Therefore, the infusion port base and butterfly wings should be effectively fixed during the use of the infusion port to ensure smooth infusion. Moreover, during use, the implanted intravenous infusion port may have related complications, such as fluid extravasation, catheter-related bloodstream infection, thrombosis, catheter blockage, catheter displacement, damage or breakage, etc., so the situation around the infusion port and the safety needle should be closely observed.
