Abstract

A self-closing catheter valve having a housing with an oval cross section and a conical hose attachment connector which can be inserted into a catheter hose. A valve hose piece partially extends through the housing. A V-shaped spring element deforms and constricts the valve hose piece by pressing the valve hose piece against a wall of the housing. An actuation member is positioned within the housing for bringing the self-closing catheter valve into an open position.
