Abstract: Coupling arrangements and connectors for establishing a substantially fluid-tight removable connection between a fluid port in a medical device such as an endoscope. Various embodiments of the connectors may be coupled to a fluid conduit that may be attached to a decontamination or reprocessing device used to flow fluid through corresponding channels in the medical device during the decontamination process.

Abstract: A method for attaching a test fixture to a surgical instrument comprising removing a valve member from a valve chamber of a surgical instrument and removing another valve member from another valve chamber of the surgical instrument. The method further comprises inserting a valve member analogue extending from a frame of a test figure into the valve chamber, wherein the valve member analogue comprises a first seal and a second seal, and wherein the first and second seals are configured to seal at least a portion of the valve chamber of the surgical instrument. The method further comprises inserting another valve member analogue extending from the frame, wherein the valve member analogue and the another valve member analogue define a longitudinal axis extending substantially therebetween. The method further comprises securing the test fixture to the surgical instrument by moving the housing substantially perpendicular to the longitudinal axis into a locked position.

Abstract: A decontamination system including a test fixture configured to engage an endoscope in order to retain the test fixture thereto, wherein the endoscope can comprise a valve chamber and a valve removable from the valve chamber such that the test fixture can be inserted therein. The test fixture can comprise, first, a frame having a first gripping portion and a valve member analog extending from the frame, and, second, a housing having a second gripping portion movable relative to the frame between a locked position and an unlocked position, wherein the second gripping portion is configured to be moved toward the first gripping portion to position the housing in its unlocked position. The second gripping portion can be configured to be moved away from the first gripping portion to position the housing in its locked position such that the housing can engage a locking feature on the endoscope.

Abstract: Coupling arrangements and connectors for establishing a substantially fluid-tight removable connection between a plurality of fluid ports or channels in a medical device such as, an endoscope. Various embodiments of the connectors may be coupled to a plurality of fluid conduits that may be attached to a decontamination or reprocessing device used to flow fluid through corresponding channels in the medical device during the decontamination process.

Abstract: An instrument reprocessor for cleaning, disinfecting, and/or sterilizing a medical instrument is disclosed. To reprocess instruments having one or more channels defined therein, the reprocessor can include one or more flow control systems configured to control a flow of fluid through each channel. In various embodiments, a flow control system can include a differential pressure sensor and a proportional valve for controlling the fluid flow in a channel. The reprocessor can also include, one, a fluid circulation pump which can be configured to supply the flow control systems with fluid and, two, a system for controlling the pressure of the fluid supplied to the flow control systems. The reprocessor can also include a system for supplying a metered amount of fluid to the fluid circulation system. The system can include a reservoir having a fluid height sensor to monitor the amount of fluid therein and a pump configured to supply the reservoir with fluid.

Abstract: A method measures a property of a solution spectroscopically by placing a quantity of the solution into a cuvette and passing a light therethrough. A reservoir receives a quantity of the solution and bubbles are driven off prior to putting a sample therefrom into the cuvette for measuring.

Abstract: A valve is provided which includes a valve body, a first valve member, and a second valve member. The valve body has a first flow passage formed therethrough and a second flow passage formed therein. The second flow passage has a smaller cross-sectional area than the first flow passage so that the valve can be used interchangeable between systems requiring different flow rates through the valve, and so that flow through the valve can be more accurately controlled than through the first flow passage alone.

Abstract: A vaporizer provides enhanced removal of non-vaporizable components from a liquid to be vaporized. Flow of vaporizing fluid through the vaporizer follows a circuitous path to allow the non-vaporizable components to adhere to surfaces in the vaporizer rather than leave in the vaporized flow.
