Problems solved by technology

[0016] One advantage of all known systems is that the system has two cartridges and therefore may not be easy to operate with compressed air
Furthermore, the cartridge containing the accelerator occupies an unnecessarily large volume, since otherwise a homogeneous distribution and thus a homogeneous mixing cannot be achieved

Embodiment Construction

[0111] figure 1A schematic sectional view of a mixing device according to the invention is shown. The mixing device comprises a rotationally symmetrical housing 2 made of thermoplastic material. The housing 2 is produced as a cylindrical tube which tapers obliquely in the upward direction by means of a conical section and is then cylindrical again. Openings 4 , 6 are provided at both ends of the housing 2 . The multicomponent mixture (not shown) to be produced can be extruded through the upper opening 4, while the first component (not shown) is pressed into the housing 2 through the lower opening.

[0112] External threads 8 , 10 are provided on both ends of the housing 2 . A distribution tube (not shown) with a static mixer can be screwed / screwed onto the upper thread 8 . A cartridge (not shown) containing the first component is fastened to the lower thread 10 . The cartridge includes a plunger operable to force the first component into the housing. The cartridge and di...

Abstract

A mixing device produces a multi-component mixture, in particular for medical applications, and has at least one first component and one second component, whereby the first component is a pasty fluid mass, whereby the mixing device has a housing having at least one first opening and a hollow body, whereby the hollow body has an internal space that contains the second component, and the mixing device has a feed plunger for expelling the second component from the internal space of the hollow body, whereby the hollow body has a thread and the feed plunger has a counter-thread that engages the thread of the hollow body, and the mixing device has a propulsion element that is arranged inside the housing, whereby the propulsion element converts a flow of the first component through the housing into a rotary motion, whereby the rotary motion of the propulsion element screws the feed plunger into the internal space of the hollow body, and whereby the second component can thus be extruded from the hollow space into the fluid flow of the first component.

Description

technical field [0001] The invention relates to a mixing device for producing a multicomponent mixture, in particular for medical applications, comprising at least one first component and one second component, whereby the first component is of fluid quality, in particular Ground is pasty quality, thus mixing device comprises a kind of shell with at least one first opening and a kind of hollow body, and wherein hollow body comprises the inner space that contains second component, and mixing device comprises a kind of feeding plunger for expelling the second component from the interior space of the hollow body. [0002] The invention also relates to a cartridge system with a mixing device of this type and an applicator with a cartridge system of this type. And finally, the invention also relates to a method for producing multi-component mixtures, in particular using a mixing device of this type. [0003] The mixing equipment used for mixing and, if applicable, for applying the...
