Wearable uroflowmetry systems having wearable uroflowmeters, and methods of operating the same are disclosed. A disclosed example uroflowmetry system comprises 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 configured to capture urine excreted by the person when the end is secured against the person, and to direct the captured urine into the outlet; a fluid passage portion having an opening configured to receive the 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; and a measuring portion having a sensor in the fluid channel configured to collect one or more measurements of the urine as the urine passes the sensor, the measurements representative of at least one of a property of the urine, or a flow characteristic of the urine.

Absorbent articles with biodegradable and/or biocompostable elements are disclosed, wherein the absorbent articles include sensors. The sensors detect and determine variables associated with collected fluids, solids, and gases, including a presence of fluids, solids, and gases, a volume of fluids, solids, and gases, and/or a distribution of fluids, solids, and gases. In one embodiment, the sensors and/or connected computing systems are calibrated to capacities and other properties of elements within the articles, including superabsorbent polymers, and are operable to trigger an alert based on detected or determined conditions.

A method for collecting and analyzing urine at the time it is released uses a urine collecting tube joined with a canister. Suction is produced in the collecting tube to join the tube with a penis or to the exterior surface of a female urethra orifice. Once suction is achieved the collecting tube stays in place by suction action. When urine flows into the urine collecting tube a sensor triggers a vacuum pump to produce a higher level of suction to flush the urine into the canister where a level sensor determines the quantity of urine received. Various sensors in the canister determine levels of non-urine partials such as occult blood, drugs, salt, and other substances. When urine is no longer detected within the urine tube, the vacuum pump is turned off and a low-level vacuum remains to assure interconnection with the urine tube.

A portable urination weight measurement device comprising: a holding unit for releasably holding a container, and a handle comprising a weight measurement unit coupled to the holding unit so as to allow the measure of a weight exerted on the holding unit; and a toilet flushable container having: a rim having a fold at a front side of the opening and a fold at a back side of the opening, each fold forming at rest an angle of less than 20, and a collar secured to the rim and comprising at least one fold at the front side of the opening forming at rest an angle of less than 20, the collar being of a rigidity such that increasing the angle of the collar fold to 180 increases the angle of the rim fold at the back of the opening to from 50 to 90.

A ureteral catheter is provided, including a drainage lumen including a proximal portion and a distal portion configured to be positioned in a patient's kidney, renal pelvis, and/or in the ureter adjacent to the renal pelvis, the distal portion including a retention portion for maintaining positioning of the distal portion of the drainage lumen, the retention portion including at least two openings on a sidewall of the retention portion for permitting fluid flow into the drainage lumen wherein a total area of a proximal most opening of the at least two openings is less than a total area of more distal opening(s) nearer to the distal end of the drainage lumen, and wherein when negative pressure is applied through the ureteral catheter, fluid is drawn into the ureteral catheter through the at least two openings.

A device for collecting urine discharged from a body of a user includes a fluid collection assembly having at least one layer for drawing urine discharged from the body into an interior cavity, an external covering that covers a portion of the at least one layer, and at least one fenestration for receiving urine, wherein the fenestration is a portion of the fluid collection assembly that is uncovered by the external covering. The device further includes a cap enclosing a first end of the assembly, a tube having a first end in fluid communication with the cap, and a shape retaining element configured to conform the assembly to a curved configuration and maintain the curved configuration until the configuration is adjusted. The assembly is configured to be disposed against the body of the user, with the at least one fenestration in operative relation with a urethral opening of the user.

A sensor is provided for measuring a flow of a fluid in a physiological environment, such as within a vessel of a human or animal subject. The sensor comprises an interrogation light guide extending from a proximal end to a distal end of the sensor. The interrogation light guide is configured to transmit interrogation light to, and receive reflected interrogation light from, the distal end of the sensor. The sensor further comprises an excitation light guide configured to transmit excitation light to the distal end of the sensor. The excitation light is provided for heating the fluid (directly or indirectly). The sensor further comprises a sensing element located at the distal end of the sensor. The sensing element comprises at least two etalons for reflecting interrogation light back along the interrogation light guide towards the proximal end of the sensor. Each etalon has a respective optical path length and further has at least one reflective surface external to the interrogation light guide. The sensing element is configured to be in thermal contact with the fluid such that the optical path length of at least one etalon is dependent on a temperature of the fluid. The reflected interrogation light forms an interferogram which is dependent on the optical path lengths of the respective etalons.

A smart patch including multi-component strands integrated into clothing or other textiles where the strands of the smart patch include sensory elements that can simultaneously measure tactile forces, moisture/wetness, and other signals, such as biopotentials. A sensing system comprising: a first set of strands including a plurality of first multi-component strands, each of the first multi-component strands including a conductive portion and a non-conductive portion; and a second set of strands including a plurality of second multi-component strands, each of the second multicomponent strands including a conductive portion and a non-conductive portion, and a plurality of third multi-component strands, each of the third multicomponent strands including a conductive portion and a non-conductive portion, the third multi-component strands being different than the first multi-component strands and the second multi-component strands.

A patient monitoring system is disclosed comprising at least one processor programmed to process medical data derived from a patient or medical records repository and to compose interconnected cascades of sepsis by linking or grouping four fundamental elements which comprise; a perturbation, at least one perturbation force which is capable of inducing and may have induced the perturbation, a recovery, and at least one recovery force which is capable of inducing and may have induced the perturbation. The four elements are linked or grouped by the processor to generate a quaternary which may be characterized as solved or unsolved.

Devices, systems, and methods herein relate to predicting infection of a patient. These systems and methods may comprise illuminating a patient fluid in a fluid conduit from a plurality of illumination directions, measuring an optical characteristic of the illuminated patient fluid using one or more sensors, and predicting an infection state of the patient based at least in part on the measured optical characteristic.
