Method for liquid disinfecting and sterile rinsing
First Claim
1. A method for disinfecting articles and the exterior and interior surfaces of the vessel in which the articles are disposed in an apparatus for use with a conventional supply of fluid, where the apparatus has an outer vessel and an inner vessel so disposed within the outer vessel that an outer chamber is defined therebetween, the method comprising:
- placing the articles in the inner vessel of an apparatus having an inner vessel so disposed within an outer vessel that an outer chamber is defined therebetween;
washing the articles;
draining the inner vessel;
so applying a disinfectant to the articles that the disinfectant fills the inner vessel and flows through an interface between the inner vessel and a cover on the inner vessel to so fill the outer chamber that the inner vessel is submerged for a period of time sufficient to disinfect the articles, the inner vessel and the cover;
draining the inner vessel and the outer chamber;
spraying sterile fluid onto the articles;
so filling the inner vessel with sterile fluid that the articles are substantially submerged and the sterile fluid flows through the interface and over the exterior surface of the cover, establishing a direction of flow for preventing the entrance of contaminants into the inner vessel and rinsing the exterior surfaces of the cover, for a period of time sufficient to soak the articles;
agitating the sterile fluid within the inner vessel; and
draining the inner vessel and the outer chamber.

Abstract
A method for disinfecting articles placed within an apparatus for use with a conventional supply of fluid. The apparatus includes an outer vessel, an inner vessel so disposed within the outer vessel that an outer chamber is defined therebetween, means for covering the inner vessel, means of introducing fluid into the inner vessel, and means for selectively draining the inner and outer vessels. There may also be means for agitating the fluid in the inner vessel. The method includes the step of washing the articles, rinsing with fluid, so applying disinfectant to the articles that the disinfectant fills the inner vessel and flows through an interface between the inner vessel and a cover on the inner vessel to so fill the outer chamber that the inner vessel is submerged, draining the inner and outer vessel, spraying sterile fluid onto the articles, so filling the inner vessel with the sterile fluid that the articles are submerged and the sterile fluid overflows through the interface and over the exterior surface of the cover to establish a direction of flow which prevents the entrance of contaminants into the inner vessel, but does not fill the outer chamber so that the exterior of the inner vessel is not submerged. The sterile fluid flows over the exterior of the inner vessel. The sterile fluid is agitated in the inner vessel, then drained from the inner and outer vessels.
