Abstract: A method of cleaning an endoscope in a computer-controlled washer/disinfector comprising the steps of connecting each lumen of an endoscope to a fluid distribution system for selectively conveying pressurized air or pressurized fluids through lumens in an endoscope; identifying the type of endoscope to be cleaned in said washer/disinfector; determining a blockage threshold flow coefficient for each lumen for said endoscope to be cleaned; pressurizing each lumen in said endoscope individually and determining an actual flow coefficient through said lumen; determining whether said endoscope is suitable for cleaning by comparing said actual flow coefficients for a lumen in said endoscope to said blockage threshold flow coefficient for said lumen; and determining whether a connection to a lumen in said endoscope is properly connected based upon said flow coefficient through said lumen.

Abstract: A washer having a plurality of water inlet diffusers, each diffuser connected to a water inlet line for directing the flow of fluid into the washing chamber. The water is directed, i.e., sprayed against the surfaces of the washing chamber to modify (adjust) the temperature of the washing chamber gradually prior to the start of a particular phase of a washing cycle.

Abstract: A tunnel washer that includes fluid exhaust paths that are optimized to minimize fluid transfer between chambers of the washer and minimize heat loss from each chamber of the washer. The fluid exhaust paths also facilitate uniform vapor evacuation from each chamber of the washer. The tunnel washer also includes spaced-apart double wall curtains for isolating chambers of the tunnel washer to prevent fluid and heat transfer therebetween, and to the exterior of the tunnel washer. The double wall curtains include surfaces that inhibit the curtains from sticking together during operation of the tunnel washer. The tunnel washer also includes an air manifold that provides uniform drying efficiency for articles of varying dimensions.

Abstract: A method of drying articles within a washer comprising: creating an airflow from an upper compartment of a chamber to a lower compartment of the chamber through a gap such that a curtain of air is formed along side walls of the chamber; creating an air flow from the lower compartment to the upper compartment through an opening therebetween wherein a portion of the curtain of air is drawn in a first direction over articles in the lower compartment and a portion of the curtain of air continues along the side walls and is redirected in a second direction over the articles in the lower compartment; heating the air in the upper compartment to a temperature sufficient to vaporize fluid in the chamber; venting a portion of the air in the lower compartment; and introducing clean filtered air into the upper compartment.

Abstract: A method of drying articles within a washer by creating an airflow from an upper compartment to a lower compartment within the washer.

Abstract: The present invention provides a washer for washing articles. A housing of the washer defines a chamber. A partition divides the chamber into an upper compartment and a lower compartment. An outer peripheral edge of the partition generally conforms to side walls of the housing such that a gap is formed between the edge of the partition and the side walls of the housing. A blower assembly disposed in the upper compartment has a first air inlet, a second air inlet and an air outlet. The first air inlet fluidly communicates with the lower compartment. The second air inlet fluidly communicates with an external air inlet line. The air outlet fluidly communicates with the upper compartment. An impeller is provided to circulate air from the lower compartment and from the air inlet line into the upper compartment. A heating means heats the air in the upper compartment.
