Abstract
An indwelling catheter including: a hollow catheter base having a tip and a back end, the back end being able to receive and connect a male connector; a tube provided at the tip of the catheter base; a flexible hemostasis valve installed inside the catheter base; a pusher installed at a back of the hemostasis valve; and a pusher guide installed between the pusher and the catheter base. The pusher has a hollow constitution whose taper reduces in diameter facing its tip. The pusher guide is able to restrict a position of the pusher at a first position where the pusher does not push open the hemostasis valve and a second position where the taper of the pusher is positioned inside the hemostasis valve and pushes open the hemostasis valve.
