Filed:
Jun 26, 2001
Appl. No.:
09/891810
Inventors:
David Levell - Las Vegas NV, US
International Classification:
A61M001/00
US Classification:

Abstract:
A valve assembly apparatus includes a main body portion which includes a top main body portion and a bottom main body portion. The bottom main body portion includes a container connector portion. A one-way vent valve is in air way communication with the bottom main body portion. A one-way liquid flow valve is supported by the main body portion. A tubing adaptor is connected to the top main body portion. The valve assembly apparatus can be used to direct urine from a urinary drainage tube into a urine reception container. The one-way liquid flow valve prevents urine from flowing backward up into the urinary drainage tube, and the one-way vent valve prevents urine from leaking from the urine reception container if the container is tipped over.
