Connector set for medical use and indwelling catheter set using such connector set

摘要

A connector set for medical use includes: (a) a cannula housing; and (b) an infusion hub to be detachably connected to the cannula housing from its proximal end. The cannula housing includes: (a) a catheter hub, a proximal end of which is formed into a connecting port; and (b) a plug of resilient material for sealing the connecting port and inserted into the connecting port. The infusion hub includes: (a) an infusion needle formed into a hollow body opened at its distal and proximal ends, and being detachably inserted into the plug from its proximal end when connecting the infusion hub and the cannula housing; and (b) an infusion tubing hub provided at a proximal end of the infusion needle, the infusion tubing hub being detachably connected to the catheter hub from its proximal end when connecting the infusion hub and the cannula housing.
