Patent number: 9089880Abstract: Apparatus and methods for processing an item, such as a lumened instrument, secured in a connectorless fashion in a push/pull reprocessor. The push/pull reprocessor includes a container having a first chamber and a second chamber and a pressure sensor in each chamber such that the method includes the step of generating a flow of a liquid, such as ozonated water, back-and-forth upon the item or additionally through a lumen in the case of a lumened instrument.Type: GrantFiled: June 16, 2014Date of Patent: July 28, 2015Assignee: Langford IC Systems, Inc.Inventor: Terrence R. Langford

Patent number: 9023277Abstract: Methods and apparatus for liquid, gas, and gas plasma sterilization of items. The apparatus includes two chambers and a holder to connectorlessly secure a lumened instrument such that a first portion of the lumened instrument lies in the first chamber and a second portion of the instrument lies in the second chamber, a liquid medium contained within the two chambers, and pumping means for simultaneously increasing fluid pressure within the first chamber of said container while decreasing fluid pressure within the second chamber of the container in a reciprocating fashion. The pumping means displaces at least a total internal volume of the liquid medium through the lumen for a given highest volume of a lumened instrument during a stroke.Type: GrantFiled: January 10, 2014Date of Patent: May 5, 2015Assignee: Langford IC Systems, Inc.Inventor: Terrence R. Langford

Publication number: 20080066782Abstract: Methods and apparatus utilizing turbulent fluid flow to wash soiled items. A washing chamber (2) is connected to a pump (10) and contains a baffle (5) that divides or partially divides the chamber (2). The baffle (5) contains one or more openings (12) through which fluid surges in response to pressure generated by the pump (10). By using a reciprocating piston or diaphragm-type pump, back-and-forth fluid flow is generated. The fluid turbulence created by the fluid surging through the baffle openings creates a “scrubbing action” upon the surface of the items being washed.Type: ApplicationFiled: October 6, 2004Publication date: March 20, 2008Applicant: LANGFORD IC SYSTEMS, INC.Inventor: Terrence Langford
