Abstract
The urine measuring device comprises at the lower end of a drip chamber ( ) an antireflux valve which prevents liquid from a measuring chamber ( ) from refluxing into the drip chamber ( ). A valve plate ( ) capable of closing the valve opening ( ) comprises a loose part which is loosely arranged in the valve chamber ( ) and rests on a bracket ( ) when the urine measuring device is in upright position. If the urine measuring device is tilted, the urine contained in the measuring chamber ( ) presses the valve plate ( ) against the valve seat ( ) so that reflux into the drip chamber ( ) is prevented.
