Abstract: A bone cement mixer (1) includes at least one mixing space (5) for mixing powder and liquid components (2, 4) to make bone cement. The powder component (2) is placed in the mixing space (5) and the liquid component (4) in a liquid container (3). The liquid component (4) is sucked out from the liquid container (3) to the mixing space (5) by means of a vacuum generated in the mixing space. The liquid container (3) is a tube (15) that has a connecting element (16) for connecting it to the bone cement mixer (1). The connecting element (16) is adapted to be opened when it is connected to a corresponding connecting element (17) on the bone cement mixer (1). The metal material of the tube has a thickness such that the volume of its liquid containing space (18) is brought to decrease when the vacuum in the mixing space (5) is brought to prevail therein.

Abstract: A bone cement mixer includes one mixing space (5) for mixing powder and liquid components (2, 4) to make bone cement. The powder component (2) is placed in the mixing space (5) and the liquid component (4) in a liquid container (3). The liquid container (3) may be an aerosol container (15) and contains, in addition to the liquid component (4), a propellant gas for pushing the liquid component (4) out from the aerosol container (15) into the mixing space (5). The aerosol container (15) has a connecting element (16) for connecting it to the bone cement mixer (1), and it is closed and adapted to being opened when it is connected to a corresponding connecting element (17) on the bone cement mixer (1), so that the liquid component (4) is pushed out from the aerosol container (15) into the mixing space (5) by the propellant gas.

Abstract: The present invention relates to a device at a bone cement mixer, wherein the bone cement mixer (1) comprises at least one mixing space (5) for mixing powder and liquid components (2, 4), preferably a polymer and a monomer respectively, to make bone cement, the powder component (2) is placed in the mixing space (5) and the liquid component (4) in a liquid container (3), and the liquid component (4) can be transferred from the liquid container (3) to the mixing space (5) and the powder component (2) placed therein.
