Abstract
Contact lenses are purified by contact with ozone in a compact system that includes an ozone generator, a purifying liquid in a lens chamber, and a pumping system for flowing liquid and gas in a way that brings ozone dissolved in a purifying liquid into contact with the lenses. In some embodiments, undissolved ozone can also contact the lenses. Several preferred arrangements are shown for accomplishing the lens purification with such an ozone disinfection system.
Claims56
A contact lens purification system comprising:
- a. a chamber containing a contact lens submerged in a liquid configured and arranged for purification system;
- b. a generator arranged for producing an ozone containing gas;
- c. a liquid circulation passageway arranged for leading said liquid from said chamber to a junction;
- d. an output gas passageway leading said ozone containing gas from said generator to said junction;
- e. said liquid circulation passageway being arranged for leading said liquid from said junction back to said chamber;
- f. a pumping system arranged for causing said liquid to flow through said liquid circulation passageway and causing said ozone containing gas to contact said liquid at said junction for dissolving ozone in said liquid in regions downstream of said junction;
- and
- g. said liquid and gas passageways and said pumping system being sized to determine the flows of said liquid and said ozone containing gas.

A contact lens purification system comprising:
- a. a chamber configured and arranged for containing a contact lens submerged beneath a surface of a liquid;
- b. a generator arranged for producing an ozone containing gas;
- c. a pump arranged for pumping said ozone containing gas from said generator into said liquid in said chamber;
- and
- d. a porous hydrophobic diffuser arranged beneath the surface of said liquid in said chamber to cover an inlet for said ozone containing gas flowing into said chamber so that said ozone containing gas passes through said diffuser into said liquid in said chamber, and liquid in said chamber cannot pass through said diffuser toward said generator.
