Patent

CA 2040487

Male and female members for contact lenses are disclosed. Either member is able to hold the contact lens as it moves from station to station during the hydration process. The female member fits together with the male member forming a chamber. Each of the members contains a line centrally located so that both surfaces of the contact lens are flushed during the hydration process, and drainage takes place radially on the outside of the mated male and female chamber members. These members may be produced on a frame with a plurality of members, usually eight to a frame, to allow ease of processing. Full automation is possible, and complete and positive lens control during any step of the process through the packaging step is achieved.

Cette invention concerne des éléments mâles et des éléments femelles conçus pour recevoir des lentilles de contact. L'un et l'autre sont adaptés pour retenir une lentille de contact pendant son passage d'un poste à l'autre d'une installation d'hydratation. Les éléments femelles s'ajustent aux éléments mâles pour former une enceinte, chacun des deux éléments ayant une fente centrée pour que les deux faces de la lentille de contact puissent être rincés durant le procédé d'hydratation. L'évacuation de liquide d'hydratation se fait radialement par l'extérieur des éléments mâles et femelles assemblés. Plusieurs de ces membres, en général huit, peuvent être réunis dans un cadre pour faciliter le traitement. L'invention permet une automatisation intégrale, ainsi qu'un contrôle intégral des lentilles à chacune des étapes du procédé, y compris l'étape de conditionnement.
