Title:
URINE FLOW METER
Document Type and Number:
WIPO Patent Application WO/2016/152847
Kind Code:
A1
Abstract:
The objective of the present invention is to provide a compact urine flow meter capable of easily and accurately measuring an amount or speed of urine flow. In this urine flow meter, a water wheel 7 which is caused to rotate by means of a flow of urine from a urine flow pipe 20 is provided at a lower end side of the urine flow pipe 20, through which urine collected by a urine collecting unit 2 flows. The shape of a distal end portion of the urine flow pipe 20 that causes urine to impinge on the water wheel constitutes a nozzle portion 22 in which the distal end side is machined at an acute angle, and an opening portion 21 is formed in a sidewall surface of the distal end side. A guide 23 which is elongated in the longitudinal direction of the nozzle portion 22 is provided in a urine flow path between the opening portion 21 of the nozzle portion 22 and a sidewall surface on the opposite side thereto, and is disposed in such a way that a distal end of the guide 23 is elongated as far as a distal end side region of the urine flow pipe 20. The distal end of the guide 23 is formed obliquely, the configuration being such that urine flowing through the urine flow pipe 20 is introduced into the nozzle portion 22 and is guided by the guide 23, and after having been led to the distal end of the guide 23, the urine is collected at the distal end side of the guide 23 and impinges upon distal end sides of blades of the water wheel 7. The water wheel 7 is caused to rotate by means of the flow of urine, and the amount of urine flow can be detected on the basis of detected rotation information.
