Patent number: 7780910Abstract: 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.Type: GrantFiled: February 6, 2008Date of Patent: August 24, 2010Assignee: Steris IncInventors: Eric Halstead, Serge Coulombe

Patent number: 7670565Abstract: When microbial contamination is introduced into a room (20*) of an enclosure, such as a building, an HVAC system including supply ductwork (16) and a return ductwork (34) is decontaminated with hydrogen peroxide vapor. A decontamination controller (46) operates controllable baffles (22) at outlet registers (20), temporary controllable baffles (44) at inlet registers (30), and a blower system (10) to circulate hydrogen peroxide vapor from hydrogen peroxide vapor generators (42) through the ductwork in both forward and reverse directions. Further, at least portions of the baffles are closed to create dwell times in which the hydrogen peroxide vapor resides in the ductwork with minimal or turbulent flow.Type: GrantFiled: March 3, 2008Date of Patent: March 2, 2010Assignee: Steris IncInventors: Iain F.
