Abstract: A discharge arrangement includes a fluid conducting component having an outlet part, an accessory having an inlet part, and a locking ring, the inlet part of the accessory being releasably attachable to the outlet part of the fluid conducting component. The outlet part includes two or more outlets surrounded by a collar, with an outer surface of the collar having a first rotation constraining member. The inlet part includes two inlets surrounded by a sleeve, the two inlets being complementary to the two outlets of the fluid conducting component to couple the outlets to the inlets to enable a fluid communication between one of the outlets with one of the inlets.

Abstract: A mixing and dispensing system for a two-component material, such as a bone cement, the mixing and dispensing system including a handle connected to the mixer via a mixing shaft. The mixing shaft extends through the piston from the piston driving end in the direction of the outlet end in order to move the mixer in dependence on movements initiated via the handle, and with the handle being detachable, in particular in a non-destructive manner, from the mixing shaft via a connector.

Abstract: A separator element (300) is designed to prevent the passage of granulate along an axial direction (L) but to allow the passage of liquid along the axial direction (L). The separator element (300) has an internal thread (310) open towards its proximal end, and an external thread (320) open towards the distal end. At its proximal end, the separator element additionally has at least one resilient locking arm (330) which is arranged on the outer circumference and winch extends with its free end in the proximal direction. In this way, the separator element can be mounted on the discharge opening of a container (100) and, by means of a closure piece (400), can be fixed on the container in such a way that the separator element remains on the container when the closure piece is removed.

Abstract: A mixing device which can be connected to a discharge unit and is provided to mix one or more substances together as they are discharged from the discharge unit. The mixing device has a base element with a circumferential side wall and an insert which can be inserted into the base element in such a manner that at least one circumferential zone of said insert lies against the side wall of the base element in a sealing manner. A mixing structure with mixing channels is formed on the insert, through which mixing structure the substances can be discharged from the discharge unit.

Abstract: A mixing apparatus for mixing at least two components comprises a mixing chamber having a first component and at least one component chamber having a further component. The component chamber is connected to the mixing chamber by a feed line. A negative pressure device generates a negative pressure in the mixing chamber in the starting position. By activating the negative pressure device, the pressure is equalized, whereby the further component is transferred into the mixing chamber. A display apparatus is provided at the component chamber to display a pressure change in the component chamber. The display apparatus is preferably formed by elastic bellows provided at one end of the component chamber, which is disposed opposite of the end of the component chamber following the feed line.
