Measuring and/or detecting analytes in urine, and associated systems, devices, and methods

A flow cartridge for analyzing urine, the flow cartridge comprising:

• a first housing portion comprising—
• a urine inlet configured to receive urine from a patient;
• a urine outlet;
• a first channel fluidly coupled to and extending between the urine inlet and the urine outlet, wherein the first channel includes first sensing zones positioned between the urine inlet and the urine outlet;
• and
• a second channel fluidly coupled to the urine inlet, wherein the second channel includes second sensing zones positioned downstream from the urine inlet, and wherein the first channel is arranged in parallel to the second channel;
• a second housing portion releasably coupled to the first housing portion;
• and
• a sensing subassembly positioned at least partially between the first housing portion and
• the second housing portion, the sensing subassembly comprising:
• a body;
• a plurality of primary sensors comprising—
• a first sensor coupled to the body and positioned downstream from the urine inlet,
• a second sensor coupled to the body and positioned downstream from the first sensor, and
• a third sensor coupled to the body and positioned downstream from the second sensor,
• wherein each of the first, second, and third sensors is aligned with a corresponding one of the sensing zones and operable to generate sensor data based on urine flow through the corresponding sensing zone, and wherein the first sensor, the second sensor, and/or the third sensor are positioned at least partially within the channel;
• and
• a plurality of secondary sensors downstream of the urine inlet and fluidly coupled to the second channel, wherein each of the plurality of secondary sensors are aligned with a corresponding one of the plurality of secondary sensing zones and operable to generate secondary sensor data based on urine flow through the corresponding secondary sensing zones.

A flow cartridge for analyzing urine, the flow cartridge comprising:

• a first housing portion comprising—
• a urine inlet configured to receive a flow of urine;
• and
• a flow channel in fluid communication with the urine inlet and comprising a plurality of sensing zones, wherein the sensing zones are positioned in series relative to one another along a length of the flow channel;
• and
• a second housing portion releasably coupled to the first housing portion;
• a sensing subassembly positioned at least partially between the first housing portion and the second housing portion, the sensing subassembly comprising:
• a body;
• and
• a plurality of sensors coupled to the body and in fluid communication with the flow channel, wherein each of the sensors is aligned with a corresponding one of the sensing zones, wherein the sensors are each configured to measure a chemical parameter and/or a physical parameter of the urine, and wherein at least one of the plurality of sensors is positioned at least partially within the flow channel;
• and
• a processor operably associated with the sensing subassembly and a pump of a fluid therapy system, wherein the processor is configured to,
• obtain the chemical parameter and/or the physical parameter of the urine measured by one or more of the plurality of sensors;
• and
• cause the pump to administer, to a patient and based at least partially on the obtained chemical and/or physical parameter, a hydration fluid at a hydration fluid rate or a diuretic at a diuretic dosage rate.
