Abstract
Abstract Disclosed is 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.

Total Claims: 7
Claim 1
Independent Claim
132 words
A medical instrument sterilization container comprising: a housing having a bottom and sidewalls for receiving medical instruments for sterilization; a removable lid sealingly fitted over said housing, said lid having a centrally located aperture therethrough; a filter disposed in said aperture to allow the passage of condensible sterilizing gases therethrough while inhibiting the passage of contaminants; said housing bottom having two openings therethrough to drain condensate from said housing, said openings being spaced apart from one another and being laterally spaced from said aperture in said lid when said lid is fitted over said housing such that the axis of said aperture is located between said openings; and a filter disposed in each said opening in said housing bottom, said filters passing air therethrough but preventing passage of contaminants into said housing.
