AI Technical Summary

Technical Problem

Conventional contact lens cleaning methods fail to effectively remove lipids, large deposits, and grease from rigid contact lenses, often requiring manual rubbing which can cause scratches and are inconvenient, while existing devices lack automatic liquid injection and discharge, leading to splash risks.

Method used

An automatic contact lens maintenance device incorporating a flexible brush module for mechanical scrubbing and electrophoretic dissociation, with integrated storage devices for automatic liquid handling and a chloride ion-containing electrolyte solution for simultaneous protein removal and sterilization.

Benefits of technology

The device effectively removes contaminants like lipids and proteins without manual rubbing, reduces cleaning time, prevents lens damage, and enhances user convenience with automatic liquid management and enhanced cleaning efficacy.

Abstract

The present invention relates to an automatic contact lens maintenance device. [Solution] The automatic contact lens maintenance device includes a cover, a base, a brush module, a drive mechanism, and at least one storage device. The base has an internal chamber and an opening communicating with the internal chamber, and the cover is attached to the opening side of the base. The brush module includes a first brush and a second brush, the first brush attached to one side of the cover facing the base, and the second brush attached to the internal chamber, the first brush and the second brush being made of a flexible material. The first brush and the second brush of the brush module are correspondingly arranged, and a contact lens is inserted between the first brush and the second brush, and the first brush and the second brush are rotated relative to each other by the drive mechanism. The storage device is attached to communicate with the internal chamber of the base. The brush module is attached to the cleaning chamber of the present invention, and the present invention can significantly improve the cleaning effect of contact lenses by simultaneously using electrophoretic dissociation technology and mechanical rubbing technology. Furthermore, the present invention is equipped with a storage device filled with a predetermined liquid, which can automatically inject or discharge liquid into or from the cleaning chamber, thereby improving convenience and user experience.
