Abstract
Abstract A medical instruments sterilization container (10) 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: 8
Claim 1
Independent Claim
134 words
A medical instrument sterilization container, comprising: a housing having a bottom and sidewalls for containing medical instruments for sterilization, and means defining an opening for transferring medical instruments into said container; a removable lid for sealing to said means defining an opening; said housing bottom sloping to at least one location to drain condensate, said at least one location having means for removal of condensate from said container; said means for removal comprising filter means, said filter means constructed so as to pass sterilizing gas therethrough and into said container but prevent passage of particulate condensate contaminants out of said container; and means for positioning medical instruments out of contact with said filter means to prevent particulate condensate contaminants in contact with said filter means to transfer to medical instruments contained within said housing.
Claim 2
Dependent Claim
134 words
A medical instrument sterilization container, comprising: a housing having a bottom and sidewalls for containing medical instruments for sterilization, and means defining an opening for transferring medical instruments into said container; a removable lid for sealing to said means defining an opening; said housing bottom sloping to at least one location to drain condensate, said at least one location having means for removal of condensate from said container; said means for removal comprising filter means, said filter means constructed so as to pass sterilizing gas therethrough and into said container but prevent passage of particulate condensate contaminants out of said container; and means for positioning medical instruments out of contact with said filter means to prevent particulate condensate contaminants in contact with said filter means to transfer to medical instruments contained within said housing.
Claim 3
Dependent Claim
27 words
The sterilization container in claim 1 wherein said filter means comprises plural filters positioned in said housing bottom, said housing bottom sloping toward each of said filters.
Claim 4
Dependent Claim
41 words
The sterilization container of claim 1 and wherein said means for positioning medical instruments comprises a removable tray for receiving medical instruments, the bottom of said tray including apertures therethrough, said bottom of said tray sloping toward each of said apertures.
Claim 5
Dependent Claim
19 words
The sterilization container of claim 1 wherein said housing constructed of a material which has a high thermal conductivity.
Claim 6
Dependent Claim
31 words
The sterilization container of claim 1 further including a filter means removably fixed in said lid so that sterilizing gas can pass through said housing via both of said filter means.
Claim 7
Dependent Claim
26 words
The sterilization container of claim 1 wherein said filter means comprises a disposable filter element and means removably sealing said filter element in said housing bottom.
Claim 8
Dependent Claim
26 words
The sterilization container of claim 6 wherein said means removably sealing said filter means is a cap positionable against said filter element in said housing bottom.
