Abstract

Uroflowmeters and methods for processing data generated therefrom are disclosed. In one aspect, the uroflowmeter is a handheld device. The uroflowmeter includes a handle, a flow chamber coupled to the handle, and a sensor associated with the flow chamber that detects a parameter of urine received in the flow chamber. The uroflowmeter may include both reusable and disposable components. As a uroflowmeter it can identify and record data corresponding to the rate of flow over the measured duration of a void of urine, but may also timestamp the voiding act and communicate the data to an external data collection center for additional analysis and incorporation into a comprehensive voiding report or voiding diary.

Claims17

Dependent claims

A method of using a uroflowmeter, the method comprising:

receiving a urine stream through an inlet of a flow chamber;
measuring a fluid level of urine in the flow chamber via a sensor;
and
flowing the urine out of the flow chamber via an outlet of the flow chamber,
wherein the flow chamber comprises a magnet coupled to a float, and the magnet is positionable according to the fluid level of urine in the flow chamber,
wherein the magnet is coupled to the float via an arm,
wherein the sensor detects a change in an angular position of the magnet, and
wherein the uroflowmeter comprises electronics that include the sensor, and the electronics determine a rate of flow of the urine stream using the change in the angular position of the magnet and a predetermined rate of the urine evacuated from the flow chamber via the outlet.
