Abstract
Abstract A medical instruments sterilization container (10) which includes a housing (12) and a removable lid (14). A removable tray (16) is adapted to hold various medical instruments to be sterilized. The container is formed of a polymer of relatively low thermal conductivity, with a material having a relatively high thermal conductivity being added thereto in order to substantially increase the overall thermal conductivity of the container to absorb radiant heat and rapidly conduct that heat throughout the container to reduce condensate within the container.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
121 words
A medical instrument sterilization container comprising: an apertured housing having generally rigid sides dimensioned for receiving medical instruments for sterilization by gas or steam passing through said aperture; a removable lid for said housing for enabling access into said housing, for enabling insertion of medical instruments in said housing, and for sealing with said housing to maintain the sterility of the interior of said housing; said housing formed from a polymer of relatively low thermal conductivity material and mixed with a relatively high thermal conductivity material distributed substantially evenly and throughout the majority of said housing in order that said housing absorbs radiant heat and rapidly conducts the heat throughout the container to reduce the formation of condensate within said container.
Claim 2
Dependent Claim
121 words
A medical instrument sterilization container comprising: an apertured housing having generally rigid sides dimensioned for receiving medical instruments for sterilization by gas or steam passing through said aperture; a removable lid for said housing for enabling access into said housing, for enabling insertion of medical instruments in said housing, and for sealing with said housing to maintain the sterility of the interior of said housing; said housing formed from a polymer of relatively low thermal conductivity material and mixed with a relatively high thermal conductivity material distributed substantially evenly and throughout the majority of said housing in order that said housing absorbs radiant heat and rapidly conducts the heat throughout the container to reduce the formation of condensate within said container.
Claim 3
Dependent Claim
14 words
The sterilization container in claim 1 wherein material with high thermal conductivity comprises carbon.
Claim 4
Dependent Claim
11 words
The sterilization container in claim 2 wherein said polymer comprises polysulfone.
Claim 5
Dependent Claim
16 words
The sterilization container in claim 1 wherein said material with high thermal conductivity comprises a metal.
Claim 6
Dependent Claim
11 words
The sterilization container in claim 4 wherein said metal comprises aluminum.
Claim 7
Dependent Claim
11 words
The sterilization container in claim 5 wherein said polymer comprises polypropylene.
Claim 8
Dependent Claim
11 words
The sterilization container in claim 5 wherein said polymer comprises polysulfone.
Claim 9
Dependent Claim
128 words
A medical instrument sterilization container comprising: an apertured housing having generally rigid sides dimensioned for receiving medical instruments for sterilization by gas or stream passing through said aperture; a removable lid for said housing for enabling access into said housing, for enabling insertion of medical instruments in said housing, and for sealing with said housing to maintain the sterility of the interior of said housing; said housing formed from a polymer of relatively low thermal conductivity material and coated at least on the inside surface thereof with a relatively high thermal conductivity material distributed substantially evenly and throughout the majority of said housing in order that said housing absorbs radiant heat and rapidly conducts the heat throughout the container to reduce the formation of condensate within said container.
Claim 10
Dependent Claim
