Title
(DE) OPHTHALMOCHIRURGISCHE KASSETTE
(EN) OPHTHALMIC SURGICAL CASSETTE
(FR) CASSETTE DE CHIRURGIE OPHTALMOLOGIQUE
Abstract
(DE) Ophthalmochirurgische Kassette, aufweisend: - einen Kassettenkörper, welcher an einer Schmalseite eine erste Aussparung aufweist, welche im Querschnitt in Form eines Kreissegmentes mit einem Kreisbogen ausgebildet ist, wobei die Aussparung so ausgebildet ist, dass ein Umfang eines Rades einer Peristaltikpumpe in die erste Aussparung eingreifen kann, - eine Aspirationsleitung für den Transport eines mittels der Peristaltikpumpe aspirierten Fluides, - wobei entlang des Kreisbogens des Kreissegmentes in radialer Richtung eine zweite Aussparung im Kassettenkörper vorgesehen ist, deren Wandung einen Fluidkanal bildet, - wobei der Fluidkanal an einem ersten Ende mit der Aspirationsleitung verbunden ist und an einem zweiten Ende mit einer Sammelbehälterzuleitung verbunden ist, - wobei die Kassette eine Haltevorrichtung zum Halten eines elastischen Abdeckelementes aufweist, mit dem der Fluidkanal abdeckbar ist, wobei die Haltevorrichtung einen konstanten Abstand des Abdeckelementes zur zweiten Aussparung sicherstellt, so dass mittels des auf das Abdeckelement einwirkenden Rades der Peristaltikpumpe Fluid von der Aspirationsleitung durch den abgedeckten Fluidkanal zur Sammelbehälterzuleitung transportierbar ist.
(EN) The invention relates to an ophthalmic surgical cassette comprising: a cassette body which comprises: a first recess on a narrow side, which is designed, in the cross-section in the form of a circle segment having an arc, said recess being designed such that a periphery of the wheel of a peristaltic pump can engage in the first recess; an aspiration line for transporting a fluid aspirated by means of the peristaltic pump; a second recess which is arranged in the cassette body and which forms a fluid channel with the walls thereof is provided along the arc of the circle segment, in the radial direction; said fluid channel is connected to a first end by means of the aspiration line and is connected to a second end by means of a collecting container supply line; the cassette comprises a holding device for holding an elastic cover element which can cover the fluid channel, said holding device guaranteeing a constant distance between the cover element and the second recess such that fluid from the aspiration line can be transported through the covered fluid channel to the collection container supply line by means of the wheel of the peristaltic pump acting upon the cover element.
(FR) L'invention concerne un cassette de chirurgie ophtalmologique comprenant un corps de cassette comportant sur une de ses faces étroites une découpe qui en section transversale présente une forme de segment de cercle avec un arc de cercle, ladite découpe étant conçue de manière que la périphérie de la roue d'une pompe péristaltique puisse s'y insérer, une conduite d'aspiration pour le transfert d'un fluide aspiré au moyen de la pompe péristaltique, une seconde découpe étant formée dans le corps de la cassette, dans la direction radiale, le long de l'arc de cercle du segment de cercle, la paroi de cette seconde découpe formant un canal pour fluide dont une première extrémité est reliée à la conduite d'aspiration et une seconde extrémité est reliée à une conduite d'acheminement vers un contenant de collecte. La cassette présente un dispositif de retenue servant à retenir un élément de couverture élastique qui peut venir recouvrir le canal pour fluide, ledit dispositif de retenue assurant un écart constant entre l'élément de couverture et la seconde découpe, de telle sorte que sous l'action de la roue péristaltique sur l'élément de couverture le fluide est transféré de la conduite d'aspiration à la conduite d'acheminement vers le contenant de collecte, à travers le canal pour fluide recouvert.
