1. A uroflowmetry system, comprising:
a wearable uroflowmeter including:
a funnel portion having an end configured to secure the funnel portion against a person, an outlet opposite the end, and a funnel, wherein the funnel is configured to (i) capture urine excreted by the person when the end is secured against the person, and (ii) direct the captured urine into the outlet;
a fluid passage portion having an opening configured to receive the captured urine from the outlet of the funnel portion, and a fluid channel to pass the received urine along a length of the fluid passage portion, wherein the fluid passage portion includes a plurality of vanes that (i) are arranged radially around a longitudinal axis of the fluid channel, and (ii) extend inward from a wall of the fluid channel, such that the captured urine passes the plurality of vanes; and
a measuring portion having a sensor in the fluid channel configured to collect one or more measurements of the captured urine as the captured urine passes the sensor, wherein the measurements are representative of at least one of a property of the captured urine, or a flow characteristic of the captured urine.
