Abstract
A liquid collection system for collecting and discharging urine from a catheterized patient. A collection bag receives urine through the catheter, and has a drain system therein, which comprises a valve having a bactericide element over which the urine must flow as it is being drained from the bag. The bactericide element is held in an openable cage, so as to permit replacement of the bactericide element as an "as needed" basis. The bactericide disposed within the valve helps prevent retrograde contamination of the liquid collection system.
