Abstract: An adapter (14) for transferring a substance from a first container (10) into a second container, having a circumferential wall (47) suitable for housing the first container, along which a cannula body (64) extends and by which said cannula body is coaxially surrounded at least in part, said adapter also comprising a hollow cylindrical section (26) connected to the cannula body and connectable to the second container. The cannula body extends with the longitudinal axis thereof perpendicular to one side of a wall (24) running transversely with respect to the circumferential wall and the hollow cylindrical section extends with the longitudinal axis perpendicular to the other side of the wall. The adapter (14) has a cup-shaped outer body (18) having an outer circumferential wall (32) and the wall (24), running transversely to the longitudinal axis of the outer body, which has an insert (46) having the circumferential wall (47).

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 device for mixing a first substance and a second substance, or for transferring at least one of the substances, which are present in a first or second receptacle, the device including a first adapter with a circumferential wall, along which extends a cannula body, and a hollow-cylindrical section that is connected to the cannula body; a second adapter with a circumferential wall, along which extends a cannula body; and a hollow-cylindrical section that is connected to the cannula body; when the first and the second adapter are assembled, the hollow-cylindrical sections inter-engage in a liquid-tight manner, and the first and the second adapter are connected to each other in a detachably screwed manner.
