  • Publication number: 20240024528
    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. 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 a fluid circulation pump which can be configured to supply the flow control systems with fluid and 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.

  • Publication number: 20220249720
    Abstract: A decontamination system suitable for cleaning a medical device having lumens of varying diameters that join together may include a variable-orifice devices (e.g., air proportional valves). A control system may be configured to adjust the variable-orifice devices based on flow characteristics, e.g., flow rates, such that the flow rates in the medical-device lumens are similar.
