Method of chemical deodorization of articles and solutions used in medical and biological procedures
Patent number: 4681575Abstract: A method of deodorizing articles, devices, and solutions involved in or used in medical and biological procedures including endoscopic procedures and associated solutions and materials. The method is to treat the materials and solutions to be deodorized with 2,4-pentanedione as a chemical deodorant. In a preferred treating composition the 2,4-pentanedione is used as an aqueous solution containing a small amount of an essential oil-type masking agent and an oil solubilizing surfactant.Type: GrantFiled: January 23, 1984Date of Patent: July 21, 1987Inventor: Lewis Knox -
Patent number: 4675014Abstract: A method for absorbing bodily secretions while hindering the generation of odors and growth of microbes comprising applying a fibrous mass having copper cations bound through selected anions, preferably carboxymethyl, the amount of chemically bound copper being between 0.1 and 3% by weight. The fibrous mass can be in the form of a catamenial device, bandage, diaper, shoe liner, or the like.Type: GrantFiled: March 4, 1985Date of Patent: June 23, 1987Assignee: Henkel Kommanditgesellschaft auf AktienInventors: Scarlet Sustmann, Ingo G.
