(FR) INJECTEUR POUR L'INJECTION D'UN FLUIDE AUXILIAIRE DE CHIRURGIE DANS UN ŒIL AINSI QUE PROCÉDÉS DE PRODUCTION D'UN FLUIDE AUXILIAIRE DE CHIRURGIE
Abstract
(DE) Die Erfindung betrifft einen Injektor (1) zur Injektion eines Operations-Hilfsfluids (20) in ein Auge, welcher einen Aufnahmebereich zur Aufnahme zumindest eines Fluidbestandteils des Hilfsfluids (20) aufweist, wobei der Injektor (1) eine Mischungseinrichtung zur Erzeugung des Hilfsfluids (20) mit einem ersten Aufnahmebereich (13) mit einem einen ersten Fluidbestandteil des Hilfsfluids (20) bildenden viskoelastischen Fluid (11) aufweist und einen davon separierten zweiten Aufnahmebereich (9) mit einem einen zweiten Fluidbestandteil des Hilfsfluids (20) bildenden Farbstoff (10) aufweist, und die Mischungseinrichtung derart ausgebildet ist, dass in dem Injektor (1) selbst ein Mischen des viskoelastischen Fluids (13) und des Farbstoffs (10) zum Hilfsfluid durchführbar ist. Die Erfindung betrifft auch ein Verfahren zum Erzeugen eines Operations-Hilfsfluid (20).
(EN) The invention relates to an injector (1) for the injection of a surgical auxiliary fluid (20) into an eye, which injector has a receiving region for receiving at least one fluid component of the auxiliary fluid (20), wherein the injector (1) has a mixing device for generating the auxiliary fluid (20) comprising a first receiving region (13) with a viscoelastic fluid (11) forming a first fluid component of the auxiliary fluid (20) and a second receiving region (9) separated from the first receiving region and with a dye (10) forming a second fluid component of the auxiliary fluid (20), and the mixing device is configured in such a way that a mixing of the viscoelastic fluid (13) and the dye (10) into the auxiliary fluid can be carried out in the injector (1) itself. The invention also relates to a method for generating a surgical auxiliary fluid (20).
(FR) L'invention concerne un injecteur (1) pour l'injection d'un fluide auxiliaire de chirurgie (20) dans un œil, qui présente une zone de réception pour la réception d'au moins un composant de fluide du fluide auxiliaire (20). L'injecteur (1) comporte un système de mélange pour la production du fluide auxiliaire (20), comprenant une première zone de réception (13) présentant un fluide viscoélastique (11) formant un premier composant de fluide du fluide auxiliaire (20) et un colorant (10) formant une deuxième zone de réception (9) séparée de la première présentant un deuxième composant de fluide du fluide auxiliaire (20). Le système de mélange est réalisé de manière qu'un mélange du fluide viscoélastique (13) et du colorant (10) pour donner le fluide auxiliaire se fasse de lui-même dans l'injecteur. L'invention concerne également un procédé de production d'un fluide auxiliaire de chirurgie (20).
