Abstract

Abstract A method for cleaning a prosthesis in a microwave oven. The inventive method preferably uses a container having an opening at the top thereof, a cover which is removably positionable over the opening, and a holding assembly removably positionable in the container, for holding the prosthesis. Since most prostheses contain at least somes metallic parts, the container and cover are each composed of a microwave insulating material. The inventive method provides for the quick and efficient cleaning of prostheses and facilitates the removal of dangerous fungal and bacterial deposits therefrom.

Claims Analysis

Total Claims: 4
Claim 1
Independent Claim 53 words
A method of cleaning a prosthesis, said prosthesis comprising a metallic portion, comprising the steps of: (a) placing said prosthesis, water, and an effective amount of a denture cleanser for cleansing said prosthesis in a microwave insulating device; and (b) then heating the contents of said microwave insulating device in a microwave oven.
Claim 2
Independent Claim 53 words
A method of cleaning a prosthesis, said prosthesis comprising a metallic portion, comprising the steps of: (a) placing said prosthesis, water, and an effective amount of a denture cleanser for cleansing said prosthesis in a microwave insulating device; and (b) then heating the contents of said microwave insulating device in a microwave oven.
Claim 3
Dependent Claim 219 words
The method of claim 1 wherein said microwave insulating device comprises: a container having an opening at the top thereof, said container comprising a microwave insulating material; a cover removably positionable over said opening, said cover comprising a microwave insulating material; and a holding means, removably positionable in said container, for holding said prosthesis and for facilitating fluid circulation through and under said prosthesis, said prosthesis being removably held in said holding means in step (b), said holding means comprising: a first upwardly extending elongate member, a second upwardly extending elongate member spaced apart from said first upwardly extending elongate member, a first support member connected between said upwardly extending elongate members and having a sloping upper surface such that said elongate members and said sloping upper surface form a restriction for gravitationally holding said prosthesis on said sloping upper surface and against said upwardly extending elongate members, and an upwardly extending second support member connected to said first support member and having an arcuate upper edge which is positionable beneath said prosthesis for retaining said prosthesis in said restriction and for at least partially holding said prosthesis above said sloping upper surface, wherein said container and said cover are operable for substantially completely enclosing said prosthesis such that said prosthesis can be safely microwaved in said microwave oven.
Claim 4
Dependent Claim 76 words
The method of claim 2 wherein: said microwave insulating device further comprises standing means, positioned at the lower end of said holding means, for standing said holding means on a substantially horizontal surface and said method further comprises the steps of: (c) removing said holding means, and said prosthesis being held therein, from said container; (d) rinsing said prosthesis; and (e) standing said holding means, and said prosthesis being held therein, on a substantially horizontal surface.
