  • Publication number: 20040226898
    Abstract: A system capable of cleaning and disinfecting a filter. A filter element is flushed with a disinfectant solution in a direction opposite to fluid filtration. A filter integrity test checks the integrity of the filter by pressurizing the filter.

  • Publication number: 20030190256
    Abstract: An automated endoscope reprocessor (10) includes a removable rack (12) for receiving a container (16, 16′). The container has a clamshell housing (20) having two mating portions (24, 26). The portions together define an internal pressurizable chamber (56) for receiving an endoscope head (22). The endoscope's connector cord (82) is carried through an outlet (80) to the chamber. The outlet is defined by channels (88, 90), one in each of the two housing portions (24, 26). A gasket assembly in the outlet provides a restricted fluid passage which allows a small portion of fluid to flow through the outlet when the connector cord is positioned therein. The gasket assembly (120) includes a number of resiliently flexible fins (126, 128, 130) positioned in each channel, each fin having a U-shaped slot (144, 146, 148). Pairs of fins overlap such that the slots together define openings (150) of diminishing size.

  • Publication number: 20030190257
    Abstract: A cartridge holder (30) for an automated endoscope reprocessor (10) is mounted on a movable rack (14). As the rack is wheeled into the chamber, a connector (164) on the cartridge holder (164) automatically makes a fluid connection with a connection port (158) within the chamber. The cartridge holder includes a base (42) and a lid (44), which is pivotally connected to the base by a hinge (110). A cartridge (40) holding a dose of a disinfectant concentrate or reagents is positioned in a well (50) defined by the base and the lid closed. Water flows through the cartridge holder via a fluid passageway (A) defined in part by the lid and in part by the hinge. The water mixes with the concentrate or reagents and the resulting disinfectant solution passes out of a lower end (205) of the cartridge into the well. The solution flows upwardly, around the cartridge, through an annular space (232) between the cartridge and the well, disinfecting the well in the process.

  • Patent number: 6510858
    Abstract: A washing device (10) includes a chamber (12) with a front door (24). The door is pivotable between a vertical closed position and a horizontal open position. An article carrying assembly (34) is moveable from inside the washing device to an upper surface (26) of the open door. A lifting system (72) moves the front door between lower and upper positions (74, 76). The lifting system includes a follower (154) to which the front door is pivotally mounted. A motor (80) transmits power to a pair of chains (110, 116), which drive the follower along a guide (156) to move the door up and down. Alternatively, the lifting system includes a cable (182) coupled to a fluid cylinder (180). When the door is in the upper position, an operator can move the rack to a transfer cart or load and unload the article carrying assembly, all while in a substantially erect position.
