Abstract: A safety needle is disclosed having a puncture needle with a needle lumen and a ground tip; a holding device that, during use, bears on the skin of a patient and holds the puncture needle; and a safety mechanism with a protection element that has a first, opened state and a second, closed state. When the holding device is taken away from the skin and/or when the holding device is moved with respect to the defined position, the safety mechanism automatically moves the protection element from a first position, in which the tip of the needle is exposed, to a second position, in which the tip of the needle is covered as the protection element at the same time transfers automatically from the first, opened state to the second, closed state.

Abstract: A syringe for the injection of an active substance and for the secondary injection of a medium, the syringe having a cylindrical syringe body with a limiting wall provided in the distal region, which transitions into a neck, two mechanically connected plungers that are axially displaceable in the syringe body, and a first actuating element for mutual displacement of the plungers, wherein, prior to the injection of the active substance, the distal plunger and the limiting wall delimit a first volume that is filled with the active substance, and mutually facing inner surfaces of the plungers delimit a second volume that is filled with the medium, wherein the plungers are displaced as a mechanically coupled unit by the application of force of the first actuating element in the direction of the limiting wall until the distal plunger comes to rest against the limiting wall or a stop.

Abstract: A withdrawal port (10) for withdrawing a liquid, in particular blood, from a tubing comprises a first tube connection (12), a second tube connection (13), and a fluid connection (15) between the first and second tube connections (12, 13).
