Abstract

A system for microbially deactivating items. The system includes a circulation system for circulating a microbial decontamination fluid through a deactivation chamber that forms a part of the circulation system. A container for holding items to be deactivated is provided. The container has a sealable cavity in which the items to be deactivated may be placed, and at least one valve element that is movable between an open and a closed position to regulate fluid flow into the cavity. An actuator in the deactivation chamber is operable to move the valve element to an open position when the container is disposed within the deactivation chamber, wherein the cavity within the container is in fluid communication with the circulation system when the valve element is in the open position.

Claims (12)

1. A container for holding items to be microbially deactivated in a reprocessor, 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 bottom wall and said side wall defining a cavity for receiving instruments and items to be microbially deactivated,

said side wall having an upper edge and a channel formed in said upper edge, said channel extending continuously about said upper edge of said side wall;

a lid attachable to said tray, said lid dimensioned to cover said cavity;

a fluid inlet in said tray communicating with said cavity;

a fluid outlet in said tray communicating with said cavity, said fluid inlet and said fluid outlet each having a one-piece, flexible valve element, said flexible valve element being movable by a mechanical actuator on said reprocessor between an open position to allow fluid flow through said container during a deactivation cycle and a closed position sealing said cavity;

wherein each of said valve elements includes a first portion movable relative to said tray and a second portion fixed relative to said tray, said first portion being connected to said second portion by a plurality of radially extending arms; and

a second fluid inlet having a flexible valve element that is movable between an open position and a closed position through contact with a mechanical actuator on a reprocessor, wherein one of said fluid inlets is in fluid communication with said channel formed in said upper edge of said side wall.

2. A container as defined in claim 1 , wherein each of said flexible valve elements has a normally closed position.

3. A container as defined in claim 1 , wherein each of said flexible valve elements is formed of a resilient flexible material.

4. A container as defined in claim 1 , wherein said fluid inlet is in fluid communication with a nozzle within said container.

5. A container as defined in claim 1 , wherein said fluid inlet is in fluid communication with fluid connectors connectable with medical instruments in said container.
