Embodiment Construction

[0155] For simplicity, identical and similar components of different embodiments in the figures are partly designated by the same reference numerals.

[0156] figure 1 A schematic perspective cross-sectional view of a storage and mixing system according to the invention is shown. The storage and mixing system comprises a cylindrical cartridge 1 as a central component, wherein a divider 2 connects two opposite inner sides of the inner wall of the cylindrical cartridge 1 . Cartridge 1 and partition 2 are designed as one integral piece joining the injection molded part, and the edges of partition 2 are each connected to the The cylindrical inner wall of the barrel 1. Its limitation can also be that the partition 2 rests against the inner wall of the cartridge 1 and is therefore not connected to the cartridge 1 in one piece. In the latter case, however, care must be taken to ensure a hermetic seal of the edge of the partition 2 with respect to the inner wall of the cartridge 1 ...

Abstract

This application relates to storage and mixing systems and methods for pasty cement components. In particular, the present invention relates to storage and mixing systems for pasty two-component polymethylmethacrylate bone cements. The invention also relates to a method for mixing the pasty cement components of the pasty polymethylmethacrylate bone cement using the storage and mixing system.

Description

technical field [0001] The present invention relates to a storage and mixing system for pasty two-component polymethylmethacrylate bone cement comprising a tubular cartridge with a cylindrical internal chamber. [0002] The present invention also relates to a method for mixing a cement mass, and in particular a paste cement component of a paste polymethylmethacrylate bone cement, using this storage and mixing system. [0003] Therefore, the subject matter of the present invention is a simple storage and mixing system for pasty two-component polymethylmethacrylate bone cement that is cost-effective to produce and can be used for mixing and mixing using manually operable dispensing devices. Polymethylmethacrylate bone cement that dispenses a highly viscous paste cement component. Background technique [0004] Conventional polymethylmethacrylate bone cement (PMMA bone cement) consists of a powder component and a liquid monomer component (K.-D.
