Abstract: The present invention relates to a connector device suitable for connecting an enteral administration set to a laminated paper packaging system comprising enterally administrable medical or nutritional food.

Abstract: A withdrawal device for the secure withdrawal of a puncture needle from a catheter, in particular from a catheter with a flexible catheter tube following the puncture. The device including a connection section for connecting the withdrawal device with the catheter in a starting position of use and a return-motion lever linearly movable in the guide element, whereby linear toothing is affixed to one of the elements, guide element and return-motion lever, which meshes with the peripheral toothing of a pivoted gearwheel on the other element (return-motion lever, guide element), and whereby the puncture needle is attached with the end protruding from the catheter such that upon rotation of the gearwheel, the puncture needle is wound up on a takeup part fixedly attached thereto.

Abstract: A coupling mechanism for connecting a catheter to a medical infusion line includes a catheter hub arranged on the catheter and a coupling piece arranged at an end of the medical infusion line for connecting with the catheter hub. A pin is axially aligned in the insertion direction of the coupling piece or a sleeve configured for receiving the pin and a locking wedge aligned parallel with the axial extension of the pin or a wedge receptacle for a form-fitting connection of the locking wedge. The wedge receptacle is defined by hinged positive locking elements which are able to move apart from each other. Lever arms are arranged at a distance from each other on the catheter hub or the coupling piece. They interact with the positive locking elements when the coupling mechanism is coupled such that the positive locking elements are spread and the locking wedge is consequently released when the lever arms are actuated.

Abstract: A puncture device with a flexible catheter tube for connecting to a medical infusion line, wherein the device includes a catheter connecting piece or hub attachable at the puncture site on the skin surface of a patient, wherein the catheter hub has a connector for connecting the infusion line and an outlet for the flexible catheter tube; and a needle holder having a puncture needle (stylet), wherein the flexible catheter tube is arranged in the interior of the catheter hub and extends out of the outlet with an output end. The end of the flexible catheter tube opposing the output end is located in the interior of the catheter hub in the area of the connector and is separated from the surrounding area by a septum, wherein the needle holder securely fastens the puncture needle insertable into a passage channel of the catheter tube at the end opposing the pointed or sharp puncture tip.
