Contact lens cleaning systems

摘要

A cleaning system configured to use a hydrogen peroxide solution to clean contact lenses. The cleaning system includes a reservoir to hold the cleaning solution and a complex base coupled to the reservoir to insure a hermetically closed reservoir environment. The complex base is separated into at least a first and a second segment. A lens holder assembly holds the lenses within the solution and is coupled to the complex base in the first segment. A motor is located in the second segment of the complex base to selectively introduce a catalyst to the cleaning solution. The cleaning system has additional features that permit the system to allow for the storage of the contact lenses by converting a neutralized cleaning solution into a storage solution to prevent recontamination.

1. An automated two-step cleaning system for the disinfection of contact lenses, the system comprising:
a single reservoir for holding a cleaning solution, said reservoir having a lens side and a disc side; a complex base comprising a lens segment, a disc segment and a bridge segment, wherein the lens segment is vertically aligned with the lens side of the reservoir, wherein the disc segment is vertically aligned with the disc side of the reservoir, and wherein the bridge segment connects the lens segment with the disc segment; the complex base being coupled to the reservoir to insure a hermetically closed reservoir environment; and a lens holder assembly configured to locate and releasably couple lenses within the reservoir, the lens holder being coupled to the lens segment of the complex base; wherein the disc segment houses a mechanism chamber having a drive mechanism configured to automatically introduce a catalyst into the cleaning solution after a predetermined disinfection time and to remove the catalyst from the cleaning solution after a predetermined neutralization time while the cleaning solution remains in the reservoir wherein the catalyst is solid and reusable.
