ABSTRACT:
A mixing device for mixing at least two substances, preferably a liquid monomer and a pulverulent polymer, for manufacturing bone cement. The two substances (16, 17) are mixed in a mixing space (9) in a mixing container (1), preferably in partial vacuum. The substances are provided separated from each other in a container (1, 18, respectively) for each substance. A mixing device (6) is provided in the mixing space (9) for mixing the two substances (16,17) therein. An opener (26), defined preferably by the mixing device (6), is provided for establishing at least one connection (27) between the separately provided substances (16, 17) and for bringing the substances in contact with each other for mixing. During opening of the connection (27) between the substances (16, 17) in the mixing space (9), the vacuum sucks one of the substances (16), preferably the liquid monomer, through the connection (27) to the other substance (17), preferably the pulverulent polymer.
