ABSTRACT:
A valve device for a catheter with a catheter hub. A tubular housing has one end provided with an outer cone for fitting into an inner cone of the catheter hub and has a valve body within acting as a locking member of an axial channel for the passage of an elongate object. The housing is provided with an axially directed protrusion forming a radial space together with the outer surface of the outer cone and has a locking member cooperating with a complementary member at the catheter hub projecting into the space so as to act as a disconnection lock. Thus, a valve device is provided that is suitable for use with a catheter system destined for venous applications according to the Seldinger method, and which ensures a reliable sealing of the extracorporal end of the catheter.
