Abstract
Abstract A urine drainage bag having an outlet tube housing a microcidal tube is disclosed. The microcidal tube is manufactured from polymeric materials capable of absorbing and releasing antimicrobial substances in a controllable sustained time release mechanism, activated upon contact with droplets of urine, thereby preventing the retrograde migration of infectious organisms into the drainage bag.
