Abstract
An antimicrobial urine collection system comprising a urine collection bag and tubing each made from a polymer, wherein the polymer comprises therein from about 0.1 to 20 phr of an antimicrobial agent. The antimicrobial agent is preferably a phosphoric acid metal salt, preferably one in which zinc is the metal. The agent can be compounded into the polymer material for forming the system components.
Claims21
