Abstract
Abstract A tube valve for use in a catheter tube, the valve having two bodies inserted in the tube, the bodies filling the cross-sectional area of the tube. Each of the bodies is provided with at least one through opening which, in the closed position of the valve in which the two bodies are in coaxial alignment with one another, is closed by the tube or by the other body but can be exposed by elastic deformation of the tube while simultaneously displacing the bodies out of coaxial alignment.
