Abstract:
1. A device for preventing free flow through a catheter for connecting an administering device to an administering needle comprising: the catheter comprising a catheter wall, and a flow region defined by the catheter wall, the catheter having a number of linear sections and intermediate sections connecting a distal end of one linear section with a proximal end of the next linear section; and a clip comprising an upper part and a lower part, the catheter arranged in the clip so that adjacent linear sections of the catheter are parallel to each other, and the intermediate section connecting one linear section to the next linear section is sharply bent, and wherein in the sharply bent intermediate sections, at least one partial piece of an inner wall abuts at least one other partial piece of the inner wall to block a flow of a medium through the catheter, wherein the partial pieces are separated when the medium exhibits a pressure above a predetermined blocking pressure, thereby permitting the flow.
