URINE MEASURING DEVICE

摘要

The urine measuring device comprises at the lower end of a drip chamber (15) an antireflux valve which prevents liquid from a measuring chamber (11) from refluxing into the drip chamber (15). A valve plate (30) capable of closing the valve opening (26) comprises a loose part which is loosely arranged in the valve chamber (34) and rests on a bracket (28) when the urine measuring device is in upright position. If the urine measuring device is tilted, the urine contained in the measuring chamber (11) presses the valve plate (30) against the valve seat (27) so that reflux into the drip chamber (15) is prevented.
