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.
L'invention concerne un dispositif d'un bac à agitation (1) destiné à la préparation de ciment osseux et comprenant un bol mélangeur (3) pourvu d'un couvercle (2) hermétique. Au moins un élément de mélange (4, 4', 4''), monté rotatif dans le couvercle (2), balaie sensiblement la totalité de l'espace interne du bol mélangeur (3) afin de mélanger délicatement les deux constituants de ciment osseux. De plus, un raccordement à une source de vide permet de créer un vide à l'intérieur du bol (3) en liaison avec la préparation. L'espace interne peut contenir un constituant du ciment osseux avant la préparation, l'autre constituant étant cédé à l'espace interne par un orifice du couvercle (2) à l'aide du vide régnant dans l'espace interne. Le dispositif comprend également un organe de commande relié opérationnellement à l'élément de mélange.
