Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
87 words
An apparatus for disinfecting contact lenses using microwave energy comprising: an outer chamber for holding a disinfecting fluid, an inner compartment containing contact lenses positioned within said outer chamber and capable of being affixed thereto and enclosed therein, wherein said inner compartment has means for substantially restricting microwave energy form contacting said contact lenses; and means for transferring disinfecting fluid, held within said disinfecting outer chamber, from said outer chamber to said inner compartment when the temperature and pressure of said fluid is elevated by microwave energy.
Claim 2
Independent Claim
87 words
An apparatus for disinfecting contact lenses using microwave energy comprising: an outer chamber for holding a disinfecting fluid, an inner compartment containing contact lenses positioned within said outer chamber and capable of being affixed thereto and enclosed therein, wherein said inner compartment has means for substantially restricting microwave energy form contacting said contact lenses; and means for transferring disinfecting fluid, held within said disinfecting outer chamber, from said outer chamber to said inner compartment when the temperature and pressure of said fluid is elevated by microwave energy.
Claim 3
Dependent Claim
38 words
The apparatus set forth in claim 1 wherein said means for substantially restricting microwave energy comprises a microwave deflecting substance effectively applied to said inner compartment so as to prevent said microwave energy from penetrating said inner compartment.
Claim 4
Dependent Claim
27 words
The apparatus as set forth in claim 1 wherein said transfer means comprises a passageway formed in said inner compartment and in communication with said outer chamber.
Claim 5
Dependent Claim
20 words
The apparatus as set forth in claim 1 wherein said outer chamber and said inner compartment are detachably joined together.
Claim 6
Independent Claim
94 words
An apparatus for disinfecting contact lenses using microwave energy comprising: an outer chamber capable of holding a disinfecting fluid; an inner compartment, capable of housing contact lenses positioned within the outer chamber and detachably affixed thereto; means for enclosing said inner compartment and said outer chamber and for directly restricting disinfecting fluid in said outer chamber from flowing into the environment; and means for transferring disinfecting fluid, held within said outer chamber, from said outer chamber to said inner compartment when the temperature and pressure of said disinfecting fluid is elevated by microwave energy.
Claim 7
Independent Claim
94 words
An apparatus for disinfecting contact lenses using microwave energy comprising: an outer chamber capable of holding a disinfecting fluid; an inner compartment, capable of housing contact lenses positioned within the outer chamber and detachably affixed thereto; means for enclosing said inner compartment and said outer chamber and for directly restricting disinfecting fluid in said outer chamber from flowing into the environment; and means for transferring disinfecting fluid, held within said outer chamber, from said outer chamber to said inner compartment when the temperature and pressure of said disinfecting fluid is elevated by microwave energy.
Claim 8
Dependent Claim
23 words
The apparatus as set forth in claim 5, wherein said enclosing means includes a cap which is detachably secured to said inner compartment.
Claim 9
Dependent Claim
23 words
The apparatus as set forth in claim 6, wherein said cap includes means thereon for suspending said contact lenses within said inner compartment.
Claim 10
Dependent Claim
31 words
The apparatus as set forth in claim 5, wherein said inner compartment comprises first and second inner cylinders coaxially joined together with means for deflecting microwave energy being mounted there between.
Claim 11
Dependent Claim
34 words
The apparatus as set forth in claim 8, wherein said disinfecting fluid transfer means comprises a passageway formed in said second inner cylinder and communicating through said first inner cylinder to said outer chamber.
Claim 12
Dependent Claim
35 words
The apparatus as set forth in claim 5 wherein said outer chamber is formed of a clear material for visually determining when the disinfecting fluid has transferred from said outer chamber to said inner compartment.
