Abstract

The machine has a sample holder fixed on top of a vertical, motor-driven rotary shaft. The sample holder is a flat plat carried on top of a flexible coupling, e.g. a rubber sandwich, on top of the shaft. The coupling will rotate the platebut is not strong enough to support its wt. which is carried on three rollers at different heights. The rollers are carried on a rotor coaxial with the shaft. The rotor is gear-driven from the shaft. Intensive mixing results from the vertical oscillations, combined with rotation and change in inclination.

Description

Agitateur de sang à plateau basculeur dans tous les sens. Blood shaker with tilting plate in all directions.

La présente invention concerne les appareils du type Agitateur " permettant de mélanger ensemble le sang avec le liquide anti-coagulant contenu dans le récipient. The present invention relates to devices of the Agitator type "making it possible to mix the blood together with the anti-coagulant liquid contained in the container.

Dans les dispositifs connus de ce genre, le plateau agitateur est actionné par un mouvement de rotation excentré ce qui est plus propice à la centrifugation qu'à un mélange rigoureux. Un autre procédé consiste à agiter le plateau en un mouvement de bascule suivant un seul axe ce qui crée un mouvement de circulation restreint et toujours identique suivant ce seul axe. In known devices of this kind, the agitator plate is actuated by an eccentric rotational movement which is more conducive to centrifugation than to a rigorous mixing. Another method consists in agitating the plate in a rocking movement along a single axis, which creates a restricted and always identical movement of circulation along this single axis.

Le dispositif de cette invention permet d'éviter ces inconvénients. Dans celui-ci en effet les flacons sont agités dans tous les sens puisque le plateau porte flacons bascule au fur et à mesure de la rotation des bras porte galets de longueurs inégales. The device of this invention avoids these drawbacks. In this one, in fact, the bottles are agitated in all directions since the bottle-carrying tray switches over as the roller-bearing arms of unequal length rotate.

Le dispositif objet de l'invention comporte une alimentation électrique distribuée par un interrupteur à un moteur, celui-ci entraîne un réducteur de vitesses dont la sortie comporte un pignon engrenant sur une couronne dentée; Selon une réalisation de l'invention cette couronne dentée solidaire d'un plateau fait tourner celui-ci. Sur ce plateau sont fixés trois galets par l'intermédiaire de bras disposés en triangle autour de l'axe du plateau et étant chacun de longueur différente. Selon une autre réalisation de l'invention ces trois galets en tournant sous le plateau porte flacons font basculer celui-ci selon des angles autorisés par la position de chacun des trois galets. Le plateau porte flacons selon une autre réalisation de l'invention peut basculer mais est retenu en rotation par un axe souple fixé à la platine porte moteur-réducteur et elle meme fixée au boîtier. The device which is the subject of the invention comprises an electrical supply distributed by a switch to a motor, the latter driving a speed reducer, the output of which comprises a pinion meshing on a ring gear; According to one embodiment of the invention, this toothed ring secured to a plate rotates the latter. On this plate are fixed three rollers by means of arms arranged in a triangle around the axis of the plate and each being of different length. According to another embodiment of the invention, these three rollers by turning under the bottle holder plate tilt the latter at angles authorized by the position of each of the three rollers. The bottle-holder tray according to another embodiment of the invention can tilt but is held in rotation by a flexible pin fixed to the motor-reduction gear holder plate and it itself fixed to the housing.

Le dessin annexe illustre à titre d'exemple un mode de réalisation du dispositif conforme à la présente invention. The accompanying drawing illustrates by way of example an embodiment of the device according to the present invention.

Tel qu'il est représenté le dispositif comporte une eli- mentation 1, un interrupteur 2 alimentant le moteur 3. Le moteur entraîne le réducteur de vitesse 4 dont la sortie comporte un pignon 5 qui engrène sur une couronne dentée 6 solidaire du plateau tournant 7. Trois bras porte galets 8 sont fixés sur le plateau tournant et supportent le plateau porte flacons 9. Au centre du plateau porte flacons un axe caoutchouc 10 permet le basculement tout en interdisant la rotation de celui-ci grâce au fait que l'axe est fixé sur la platine porte réducteur 11. L'ensemble est fixé par la platine 11 au boitier 12. As shown, the device comprises an element 1, a switch 2 supplying the motor 3. The motor drives the speed reducer 4, the output of which comprises a pinion 5 which meshes on a ring gear 6 integral with the turntable 7 Three roller support arms 8 are fixed on the turntable and support the bottle holder tray 9. In the center of the bottle holder tray a rubber pin 10 allows tilting while preventing rotation thereof thanks to the fact that the axis is fixed on the gearbox holder plate 11. The assembly is fixed by the plate 11 to the housing 12.

Le dispositif, objet de l'invention, peut etre utilisé dans tous les cas où une transfusion sanguine est nécessaire et tout particulièrement dans les cas où le mélange parfait entre sang et anti-coagulant est absolument indispensable tels que laboratoires, chirurgie. The device, object of the invention, can be used in all cases where a blood transfusion is necessary and especially in cases where the perfect mixture between blood and anticoagulant is absolutely essential such as laboratories, surgery.

Des applications particulièrement intéressantes peuvent être les transfusions dans des installations de secours ou des cantres de collectes mobiles.  Particularly interesting applications can be transfusions in emergency facilities or mobile collection baskets.
