Mixing device and method for manufacturing polymethylmethacrylate bone cement pastes

摘要

The device has a tubular hollow body (10) provided with an input side opening (30) and an output side opening (20). A rotary mounted shaft (40) is arranged in axial direction in the tubular hollow body. Threads (50) are axially arranged along an outer side of the shaft. The shaft has a section with threads. An agitator blade (60) is arranged on the shaft, where rigid mixing elements (70) at arranged at an inner side of the tubular hollow body. An independent claim is also included for a method for producing polymethyl metacrylate bone cement paste from a powdered cement component and a liquid monomer component.
