Patent number: 6656423Abstract: A sterile water generator (B) generates a stream of sterile water on demand. A water heater (130) heats incoming, unsterile water to a sufficient temperature to achieve sterilization of the water. The sterile water is then passed through a heat exchanger (110) which transfers excess heat from the sterile water to the incoming water. This reduces the energy consumption of the water heater and reduces the temperature of the sterile water ready for use. The sterile water is delivered to a site (A), at which the water is to be used, through a sterile water delivery pathway (C) to avoid recontamination of the water. A first portion (162) of the pathway is pre-sterilized by flowing steam or hot water, generated by the water heater, along the pathway (C). A second portion (212) of the pathway is sterilized with a liquid antimicrobial from the site. The first and second portions of the pathway have at least one common leg (164).Type: GrantFiled: February 7, 2000Date of Patent: December 2, 2003Assignee: Steris Inc.Inventor: Larry J. Joslyn

Patent number: 6632290Abstract: A cleaning composition includes a detectable substance which is relatively stable in the cleaning composition, for indicating whether the cleaning composition has been thoroughly removed from a vessel following a cleaning process. For pharmaceutical applications, the detectable substance is preferably a low-foaming surfactant that is detectable by high performance liquid chromatography at concentrations of around 10 ppm, or less. The surfactant is thus detectable in the same analytical procedure as are traces of pharmaceutical residues which have not been removed from the vessel. The analytical procedure is used to develop a cleaning protocol for future cleaning processes by determining the number of rinses needed for reducing the surfactant, and hence the cleaning product, and also the pharmaceutical residues, in the rinse water to predetermined acceptable levels.Type: GrantFiled: September 8, 2000Date of Patent: October 14, 2003Assignee: Steris Inc.Inventors: Sayed Sadiq Shah, Herb J.

Publication number: 20030161159Abstract: A joint (52) for connecting arm portions (40, 42) of a ceiling or wall mounted support system includes housing members (60,62) with an annular bearing (64) interposed between opposed surfaces (82,84) thereof. The housing members are clamped together on an axle (98) such that a braking force generated between the bearing and the housing member surfaces opposes rotation of one arm portion relative to the other. A variable braking force is generated between the bearing and surfaces (206) of the housing members which are generally perpendicular to the opposed surfaces (82,84). The variable braking force is generated by a spring (182) and is greatest when the arm supporting a piece of equipment (24, 26, 28, 56) is at its lowest point, relative to the horizontal. This overcomes the increased forces in the spring which otherwise tend to cause the arm portion (42) to drift upward.Type: ApplicationFiled: February 25, 2003Publication date: August 28, 2003Applicant: STERIS INC. & Ondal Industrietechnik GmbHInventor: Stefan Kupfer
