The invention relates to a device in a mixing vessel ( 1 ) intended for the preparation of bone cement and comprising a mixing bowl ( 3 ) provided with tightly sealing lid ( 2 ). Rotatably supported in the lid ( 2 ) is at least one mixing element ( 4, 4', 4 ''), which is designed to sweep over substantially the whole internal chamber of the mixing bowl ( 3 ) in order to carefully mix the two constituents of the bone cement with one another. There is, furthermore, a connection to a vacuum source in order to create a vacuum in the chamber of the bowl ( 3 ) in connection with the preparation. One of the constituents of the bone cement may be situated in the internal chamber prior to preparation and the other may be delivered to the said chamber via an aperture in the lid ( 2 ) by means of the vacuum prevailing in the internal chamber. The device further comprises a drive member operatively connected to the mixing element.
