ABSTRACT:
The present invention pertains to a device for measuring the urine flow (Uroflow) of a patient, consisting of a measuring head provided with a funnel and an outflow port, and of an electronic evaluating unit.
In a prior-art measuring device of this class, the measuring head is mounted oscillatingly in a housing. This has disadvantages in terms of the mechanical design of the measuring device and the accuracy of measurement.
To simplify the mechanical design and to increase the accuracy of measurement, the measuring head 1 is provided, according to the present invention, with a slotted pitot tube 4 forming the outflow port 30 and with a pressure sensor 18 measuring the dynamic pressure, and the electronic evaluating unit 9 calculates the flow values from the flow-proportional dynamic pressure measured.
