Title
(EN) REUSABLE CARTRIDGE ASSEMBLY FOR A PHACO-EMULSIFICATION MACHINE
(FR) ENSEMBLE CARTOUCHE REUTILISABLE D'UNE MACHINE UTILISEE EN PHACOEMULSIFICATION
Abstract
(EN)
A reusable cartridge assembly (10) for a phaco machine includes a first plate (48) with a plurality of flow channels (50) therein and a sealing gasket (58) with a sheet for sealing against the first plate (48) to prevent fluid from leaving the flow channels (50). In addition, a tube (74) is provided, fixed to the sealing gasket (58) and protruding therefrom, for enabling engagement between the tube (74) and a pump head (14) for circulation of fluid through flow channels (50). A second plate (62) is provided for applying a sealing pressure between the sheet (60) and the first plate (48). In addition, the sealing gasket (58) may include a sensing element (104) for determining pressure with the flow channels (50).
(FR)
Un ensemble cartouche réutilisable d'une machine utilisée en phacoémulsification comprend une première plaque pourvue d'une pluralité de canaux d'écoulement, et un joint d'étanchéité comportant une feuille qui sert à étanchéifier la première plaque afin que le fluide ne s'échappe pas des canaux. Un tube, fixé au joint d'étanchéité et faisant saillie de celui-ci, peut également être engagé entre la tête de la pompe pour faire circuler le fluide dans les canaux. Une seconde plaque permet d'appliquer une pression d'étanchéité entre la feuille et la première plaque. De plus, le joint d'étanchéité peut comporter un élément de détection déterminant la pression à l'intérieur des canaux d'écoulement.
