Title (EN) METHOD AND DEVICE FOR FEEDING COMPONENTS FOR BONE CEMENT INTO A MIXING VESSEL FOR THESE
(FR) PROCEDE ET DISPOSITIF D'AMENEE DE COMPOSANTS DANS UN VASE DE MELANGE POUR LA PREPARATION D'UN CIMENT OSSEUX
Abstract:
(EN) A method and an arrangement for successively feeding batches into a mixing vessel (2) under partial vacuum for the preparation of bone cement. The mixing vessel is pre-filled with a powder component (B) of said bone cement. A container containing a liquid bone cement (A) is connectable to the tubular rod (6b) of an agitator for mixing components (A, B) so that component (A) can be introduced into the mixing vessel by means of the vacuum present in said vessel. During mixing the agitator rod (6b) is sealed by a removable tightening rod. When mixing is completed tightening rod is removed from said tubular rod (6b) which now will serve as a spout for the bone cement. The bottom of the mixing vessel is movable and serves as a piston for emptying the mixing vessel through the spout.
(FR) Procédé et agencement permettant d'amener successivement des doses dans un vase de mélange (2) sous vide partiel en vue de préparer un ciment osseux. Le vase de mélange est pré-rempli d'un composant en poudre (B) du ciment osseux. Un réceptacle contenant un ciment liquide osseux (A) peut être raccordé à la tige tubulaire (6b) d'un agitateur mélangeant les composants (A, B) de façon à ce que le composant (A) puisse être introduit dans le vase de mélange grâce au vide présent dans celui-ci. Au cours du mélange, la tige (6b) de l'agitateur est fermée de façon étanche par une tige d'étanchéité amovible. Lorsque le mélange est achevé, la tige d'étanchéité est retirée de la tige tubulaire (6b) qui sert alors de tuyau d'évacuation du ciment osseux. Le fond du vase est amovible et sert de piston pour vider le vase par ledit tuyau d'évacuation.
