US 4,721,124 A · Optometric soft and rigid contact lens cleaning and storage system

Abstract

A system for storing, cleaning, and sterilizing soft and rigid contact lens. The system utilizes the circulation of cleaning fluid to clean lens which are suspended. The system consists of a container for housing a pair of off-set lens carriers and for functioning as a chamber for cleaning and sterilizing; a cap with apertures for providing a generally water-tight seal for the container and for supporting the lens carriers, and a base/pump housing connected to the bottom of the container for retaining the cleaning fluid and providing a pump mechanism for propelling the cleaning fluid into the cleaning chamber. The container has a floor with a plurality of angled apertures for providing a helically shaped spray of cleaning fluid onto the lens carriers upon manipulation of the base and pump housing. The base/pump housing attached to the bottom of the container is a flexible housing for storing the cleaning fluid and for providing a pump mechanism upon compression for forcing the cleaning fluid through the angled apertures into the cleaning chamber. An interior vessel is provided for water-tight attachment with the cover within the cleaning chamber to retain the two lens carriers side by side during storage. The lens carriers consist of two generally parallel mesh concave surfaces for retaining the contact lens. The mesh surface has a plurality of openings for allowing impact of cleaning fluid onto the retained contact lens. An electrically driven pump actuator may be utilized to cyclically compress the base and pump housing for irrigating the retained lens for a specified period of time.

Dependent claims

A system for storing, cleaning and sterilizing soft and rigid contact lenses, comprising:

a container having an internal cavity, a floor with apertures, and an upper opening;
a cover connectable over said upper opening having a generally water-tight connection, said cover having means for releasing air from said internal cavity;
one or more carriers connected to said cover and rotatably suspended above said floor within said cavity, said carrier having at least one pair of generally parallel concave surfaces hinged together, and said pair of surfaces connectable forming a concave cavity generally curved to the shape of the contact lens, the contact lens retainable within said concave cavity;
a pump/base housing having a compressible and resiliently expandable outer surface and a storage capacity, said housing having a connectable, generally water-tight attachment to a bottom portion of said container, said cavity in fluid communication with said internal cavity of said container through said aperture in said floor, said apertures being formed such that fluid directed therethrough into said internal cavity will impact on said contact lens to cause said contact lens and said carrier to rotate.
