Patent number: 7459028Abstract: A method and apparatus for removing soil from an inner surface of a lumen wall of a medical instrument are disclosed. A carrier gas entrains particles capable of sublimation at room temperature and transports the particles into and through the lumen. As the particles collide with the soil attached to the inner surface of the lumen wall, and as the particles sublime, the soil is removed from the inner surface of the lumen wall and transported out an exit of the lumen.Type: GrantFiled: July 13, 2005Date of Patent: December 2, 2008Assignee: American Sterilizer CompanyInventors: Jude A. Kral, Michael A. Centanni

Publication number: 20080283096Abstract: A method for operating a cleaning device or a cleaning system is proposed. In this case, the cleaning device is set up for carrying out a process for cleaning an article with a germicidal action. The method includes the following steps: information on a target germ with which the article could be contaminated is received; at least one process parameter of the cleaning process is selected according to the target germ in such a way that the target germ is killed with a high degree of probability during the cleaning process; and the cleaning process is carried out with the process parameter.Type: ApplicationFiled: May 7, 2008Publication date: November 20, 2008Inventors: Stefan Scheringer, Thomas Peukert, Markus Braun

Patent number: 7435380Abstract: A pseudo-plastic or thixotropic carrier having anti-malodorous components dissolved or suspended therein is sprayed on the internal surfaces of an ostomy bag or pouch. The viscoelastic properties of the carrier allow the composition to be conveniently dispensed from a spray bottle into the ostomy bag and retained on the inner walls thereof without being displaced therefrom by incoming waste during use of the ostomy bag. This allows the composition to continue to deodorize the ostomy bag headspace even after waste material begins to fill the bag.Type: GrantFiled: September 30, 2002Date of Patent: October 14, 2008Assignee: Church & Dwight Co., Inc.Inventor: Anthony E. Winston

Publication number: 20080240978Abstract: The present invention relates to the field of sterilization of items that are sensitive to e.g. temperature, pH, positive or negative pressure, radiation or oxidation. More particularly, the invention concerns a method, the use of this method and an apparatus for sterilization or disinfection, comprising the steps of contacting one or more item or part of an item with (a) a water-based fluid containing at least one enzyme, and (b) a substantially water-free environment with a gas having oxidative properties, where said step (a) precedes said step (b). According to the invention, items can be sterilized that are otherwise impaired by conventional sterilization procedures, such as laboratory items, medical items, dental items, military items, biological items, and food processing-related items.Type: ApplicationFiled: November 8, 2007Publication date: October 2, 2008Inventors: Jan Sorensen, Carl F. Simony, Bo Hansen

Patent number: RE49474Abstract: A free radical sterilization system having a chamber defining a region, and a generator for generating free radical reach effluent from a free radical electric generator and/or a vaporizer. A closed loop circulating system without a free-radical destroyer is provided for supplying the mixture of free radicals from the electric generator mixed with the hydrogen peroxide solution in the form of the effluent to the chamber. The free-radical sterilization system is used in sterilizing items in the chamber and, with an open-bottomed wound chamber, in treating wounds on a body.Type: GrantFiled: August 15, 2019Date of Patent: March 28, 2023Assignee: Sterifre Medical, Inc.Inventor: Czeslaw Golkowski
