Abstract: In automated reprocessing system (B), a leak detection system (10) evaluates the integrity of an endoscope (A), having an internal passage (66). The leak detection system includes an interior chamber (42) which is connected to the internal passage by quick connects (18, 20). A source of compressed air (22) pressurizes the chamber and internal passage to a suitable test pressure. A pressure sensor (50) and a temperature sensor (54) detect the pressure and temperature within the chamber and hence in the endoscope passage. Pressure and temperature measurements made over time are used to determine changes in the gas volume, indicative of whether leaks are present in the endoscope. If the endoscope is determined to be free of leaks, the endoscope is washed and microbially decontaminated in the reprocessing system. During the decontamination process, the pressure within the internal passage is maintained in a range at which ingress of fluid is avoided yet the endoscope is not subjected to a potentially damaging pressure.

Abstract: Rotational speed of a spray arm is regulated based on centrifugal force and a liquid jet to create a variable angle corner spray nozzle. The regulator includes a weight on a pivot and a fluid jet, the weight having a curved surface to produce a variable angle corner spray nozzle depending on the weight angle. Centrifugal force created during rotation pushes the weight outward, which increases as the spray arm rotation speed increases. The liquid jet is located out from a pivot point and tends to push the weight inward. The pushing force of the liquid jet is maximum when the weight is most inward and minimum when the weight is most outward. The regulator stabilizes the arm speed at a specific speed independent from center pivot friction and the spray arm nozzle's orientation tolerance. Speed stabilizes when centrifugal force on the weight is equal to the pushing force of the fluid jet.

Abstract: A fluid collection and disposal device for a transfer cart used for transporting wet articles is comprised of a tray disposed below articles to be transported on a transfer cart. The tray has a drain opening. A conduit extends from the drain opening to an exterior side of the transfer cart. A valve assembly is connected to the conduit for controlling fluid flow through the conduit. The valve assembly is comprised of a valve element moveable between a closed, first position restricting flow of fluid through the conduit and an opened, second position allowing flow of fluid through the conduit. An actuator is provided for moving the valve element from the closed position to the open position. The actuator is moveable by physical engagement with an external stop.

Abstract: A method for optical detection of residual soil on articles (such as medical instruments and equipment), after completion of a washing or a rinsing operation by a washer. A soil detection system provides an indication of soil on the articles by detecting luminescent radiation emanating from the soil in the presence of ambient light.

Abstract: A system is provided for transporting a movable rack assembly and transferring the movable rack assembly between a transfer cart assembly and a station. The system includes a rack support assembly, a rack locking assembly, a docking enabling assembly, and an anti-return mechanism. The rack support assembly is configured to securely and movably support the movable rack assembly thereon. The rack locking assembly is configured to lock the movable rack assembly to the rack support assembly. The docking enabling assembly is configured to enable temporary docking of the transfer cart assembly with the station for the transfer of the movable rack assembly to the station or the receipt of the movable rack assembly from the station. The anti-return mechanism is configured to actively inhibit removal of the movable rack assembly from the station when the transfer cart assembly is not secured to the station by a cart locking assembly.

Abstract: A method for decontaminating articles having porous outer surfaces. The method includes providing a decontamination chamber; conveying the articles through the decontamination chamber at a predetermined speed wherein the speed is selected such that the articles are disposed in the decontamination chamber for a predetermined period of time; providing a source of sterliant vapor, the source providing the sterilant vapor at a temperature within a predetermined acceptable temperature range and at a concentration within a predetermined acceptable concentration range; conveying a sterilant vapor from the source of sterilant vapor to the decontamination chamber; and exposing the articles to the sterilant vapor. The predetermined period of time and the predetermined acceptable concentration range of the sterilant vapor are selected such that the sterilant vapor does not penetrate the porous outer surfaces of the articles.

Abstract: A method for optical detection of residual soil in lumens of lumened or cannulated devices such as surgical endoscopes, after undergoing a decontamination process (e.g., a washing or rinsing operation). A soil detection system provides an indication of the presence of residual soil within a lumen by detecting luminescent radiation emanating from the soil on the interior of the lumen in response to excitation light.
