Patent Images
1. A method of aseptic management in and urine collecting reservoir, which method consists of substantially inhibiting the multiplication and precluding the survival of unwanted organisms in the reservoir, the method comprising:
- (1) admitting into the reservoir a polymeric body formed of a material that substantially maintains its physical and chemical integrity in the presence of fluid admitted into the reservoir, and contains a biocide effective member selected from the group consisting of methenamine mandelate, methenamine camphorate, methenamine iodoform, methenamine salicylate, methenamine sulfosalicylate, methenamine tetraiodide, methenamine anhydromethylene citrate, methenamine sulfamate, and polyoxymethylene ester for inhibiting the multiplication and precluding the survival of the organisms, and contains an acid for producing an acidic pH within the polymer; and
(2) releasing the biocide from the polymeric body at a controlled rate in a biocidal effective amount into the reservoir over a prolonged period of time for obtaining the desired results.
