MIXING DEVICE FOR MULTI-COMPONENT SYSTEMS The invention relates to a mixing device for producing a multi-component mixture, in particular for medical applications, comprising at least one first component and one second component (16), whereby the first component is a fluid mass, in particular a pasty mass, whereby the mixing device comprises a housing (2) having at least one first opening (4) and a hollow body (12), whereby the hollow body (12) comprises an internal space that contains the second component (16), and the mixing device comprises a feed plunger (20) for expelling the second component (16) from the internal space of the hollow body (12), whereby the hollow body (12) comprises a thread (18) and the feed plunger (20) comprises a counter-thread (22) that engages the thread (18) of the hollow body (12), and the mixing device comprises a propulsion element (24) that is arranged inside the housing (2), whereby the propulsion element (24) converts a flow of the first component through the housing (2) into a rotary motion, whereby the rotary motion of the propulsion element (24) screws the feed plunger (20) into the internal space of the hollow body (12), and whereby the second component (16) can thus be extruded from the hollow space into the fluid flow of the first component. The invention also relates to a cartridge system having a mixing device of this type and to an applicator having a cartridge system of this type. And lastly, the invention also relates to a method for producing a multi-component mixture, in particular using a mixing device of this type, in which a first component is being pressed into a housing (2) and generates a fluid flow therein, whereby the fluid flow drives a propulsion element (24) and makes it rotate, and whereby the rotating propulsion element (24) screws a feed plunger (20) into an internal space of a hollow body (12), whereby a second component (16) is thus extruded from the inside of the hollow body (12) into the fluid flow of the first component and mixes with the first component therein and the mixture is being extruded from the housing (2). 22 A - - - - - - - -- - - - - - - -A 12 Figure 3 |
