Device for measuring the urine flow (Uroflow) of patient
First Claim
1. A device for measuring urine flow of a patient, comprising:
- a measuring head with a funnel, the measuring head defining a vertical intake chamber communicating with said funnel, an outflow chamber provided with a drain pipe connection, said drain pipe connection including a slotted tube with vertical slot providing communication between said outflow chamber and said drain pipe connection, a pressure measuring chamber and a distribution chamber connecting each of said intake chamber, said outflow chamber and said pressure measuring chamber;
pressure sensing means connected to said pressure-measuring chamber for measuring a dynamic pressure; and
, evaluating means connected to said pressure sensing means for determining a flow value based on the dynamic pressure, that is proportional to the flow, sensed by said pressure sensing means.

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.
