Abstract
This invention relates to an apparatus for mixing bone cement in vacuum, in which mixing takes place in a container (11) from which ready-mixed bone cement (4) is adapted to be ejected by means of a piston (2) in the mixing container (1) for supplying the bone cement (4) to a hollow in the bone wherein a prosthesis is to be fixed by means of the bone cement (4), and the mixing container (1) is connectable to a vacuum device which is adapted to generate vacuum in the mixing container (1) during mixing. With a view to providing an apparatus of simple and compact design, which permits efficient retention of the mixing container during mixing, the vacuum device comprises a vacuum container (9) in which the mixing container (1) is adapted to be disposed in such a way that the mixing container spaces (3, 6) on both sides (5, 7) of the piston (2) communicate with the interior (10) of the vacuum container (9) whereby the same vacuum is obtained on both sides of the piston (2).
