Abstract

A reprocessor for microbially deactivating items. The reprocessor has a circulation system for circulating a microbial deactivation fluid through a deactivation chamber that forms part of the circulation system. A container is provided for insertion into the deactivation chamber for holding items to be microbially deactivated. The container includes a tray and a lid. The tray and lid have interlocking, integrally formed, rigid seal elements formed thereon to form a seal between the tray and the lid.

Claims (13)

1. A reprocessor for microbially deactivating items, said reprocessor comprised of:

a deactivation chamber;

a container for insertion into said deactivation chamber for holding items to be microbially deactivated, said container comprised of:

a generally cup-shaped tray having a bottom wall and a continuous side wall extending to one side from the periphery of said bottom wall, said side wall having a free edge, said bottom wall and said side wall defining a portion of said cavity for receiving instruments and items to be microbially deactivated;

a lid operable to cover said tray, said lid and tray defining a cavity to hold said items to be deactivated;

interacting seal means on said tray and said lid forming a seal between said tray and said lid, said seal means defining a convoluted path between said cavity and the exterior of said container; and

a fluid passage extending through a portion of said side wall of said container and fluidly communicating with said convoluted path; and

a circulation system for circulating a microbial deactivation fluid having a first path fluidly communicating with said cavity in said container, and a second path fluidly communicating with said fluid passage in said container and said convoluted path.

2. A reprocessor as defined in claim 1 , wherein said continuous channel is U-shaped.

3. A reprocessor as defined in claim 1 , wherein said seal means is comprised of:

a rigid first seal element formed along said free edge of said side wall, said first seal element having two, spaced-apart, rail-like projections that extend continuously around said free edge of said side wall; and

a rigid second seal element on said lid, said second seal element having continuous, spaced-apart, rail-like projections, said second seal element being dimensioned to matingly engage said first seal element on said tray, said rail-like projections on said lid being disposed between and spaced-apart from two of said rail-like projections on said tray when said lid is attached to said tray.

4. A reprocessor as defined in claim 1 , wherein said circulation system is essentially closed-loop and said microbial deactivation fluid is circulated through said closed-loop.
