Abstract

Abstract Translated from German Der Druckinfusionsapparat weist ein rotierendes Antriebsorgan (12) auf, das mit einer Profilierung (21) der Kolbenstange (16) oder des Spritzenzylinders (15) einer Spritze (18) zusammenwirkt, wodurch die Drehbewegung des Antriebsorgans in eine Linearbewegung der Kolbenstange (16) in bezug auf den Spritzenzylinder (15) umgesetzt wird. Die Linearbewegung wird erst unmittelbar an der Spritze erzeugt, so daß entsprechende Umsetzeinrichtungen im Innern der Haltevorrichtungen (10) entbehrlich sind. The pressure infusion apparatus has a rotating drive element (12) which interacts with a profile (21) of the piston rod (16) or the syringe cylinder (15) of a syringe (18), as a result of which the rotary movement of the drive element converts into a linear movement of the piston rod (16) with respect to the syringe barrel (15) is implemented. The linear movement is only generated directly on the syringe, so that corresponding transfer devices inside the holding devices (10) are unnecessary.
