Title: Instrument et procede de mesure de l'aberration d'un oeil humain
Inventor: HE JI CANG
IPC: A61B3/103
Filed: 1999-10-10
Abstract: L'invention concerne un instrument et procédé de mesure de l'aberration d'un oeil humain. Selon la théorie du lancer de rayon subjectif et une fois que l'oeil soumis au test fixe un objet test, on enregistre la distance entre les rayons incidents traversant les différents sites de la pupille et un point idéal sur le fond de l'oeil, on modifie ensuite l'angle incident de manière que les rayons incidents coïncident avec le point idéal. Le procédé consiste à calculer les moindres carrés de la modification des rayons incidents, après quoi on obtient la valeur d'aberration de la courbe bidimensionnelle et différentes valeurs d'aberration. L'invention concerne trois chemins optiques, à savoir un de mesure, un de référence et un de contrôle de la pupille. L'instrument comprend, quant à lui, un ordinateur de contrôle, un chemin optique de mesure et un réseau de diodes électroluminescentes. Selon l'invention, l'objet test se trouvant sur un afficheur à cristaux liquides est déplacé le long d'une souris d'ordinateur de manière à faire varier l'angle d'incidence pour que la lumière traverse la pupille.

Title: Implantatspritze
Inventor: KNEER ROLAND
IPC: A61B17/00
Filed: 2000-12-05
Abstract: Die Implantatspritze hat eine Führungshülse, in der eine Spritzennadelanordnung sitzt, die aus einer Spritzennadel, einer Nadelhalterung, einem Griffstück und einem Präparataufnahmeteil zusammengesetzt ist. Diese Spritzennadelanordnung ist in einem Ausgangszustand durch zwei Federarme blockiert, die aus der Führungshülse freigeschnitten sind und derart schräg nach innen ragen, dass sie an einer Rückwand der Spritzennadelanordnung anliegen. Wenn der Kolben der Implantatspritze vorgeschoben wird, um das Präparat bis zum Kopfende der Spritze vorzuschieben, läuft eine mit dem Kolben verbundene Hülse auf die Federarme auf und biegt diese nach aussen, wodurch die Spritzennadelanordnung zurückziehbar ist. Diese beiden Vorgänge werden mit einer einzigen Griffhaltung durchgeführt, wodurch die Handhabung der Implantatspritze vereinfacht ist.
