Abstract

The device for processing bone cement includes a mixing station with a stirrer for mixing the components of the bone cement under vacuum. The device also includes a resting station in which the mixed ingredients may be stationed for a resting period, processing period and curing period. The temperature-dependent reaction time on the polarmarization reaction can be taken into account in determining the discrete time intervals by means of a temperature sensor for sensing ambient temperature. Acoustic and visual signal generating devices are also provided to indicate the end of each time intervals.
