Abstract

A process for the preparation of bone cement for subsequent introduction into the cavity of a bone serving to receive a prosthesis. The components serving for the production of the bone cement are introduced into a cartridge and mixed together during a mixing phase and subsequently undergo a further resting phase. The mixing phase and the resting phase are under automatic program control.
