A measurement apparatus comprises optical components arranged to provide parallel measurements of a biological sample. The parallel sample measurements provide improved accuracy with lower detection limit thresholds. The parallel measurements may comprise one or more of Raman spectroscopy measurements or infrared spectroscopy measurements. The parallel measurements can be combined with a light source. In many embodiments, the light source comprises one or more wavelengths corresponding to resonance frequencies of one or more molecules of the sample, such as wavelengths of ultraviolet light. The wavelengths of light corresponding to resonance frequencies can provide an increased signal to noise ratio. The parallel array optical configuration can be combined with wavelengths of light corresponding to resonance frequencies in order to provide increased measurement accuracy and detection of metabolites.

Systems, devices and methods for draining and analyzing bodily fluids are disclosed in which a drainage assembly is configured to prevent negative pressure build-up. The drainage assembly generally includes a catheter which may include a drainage lumen, a reservoir, a venting mechanism in fluid communication with the drainage lumen and a positive pressure lumen, and a controller. The venting mechanism may further include a valve which is configured to maintain a closed position, as well as a vent in fluid communication with the valve, where the venting mechanism is configured to inhibit wetting of the vent from fluid within the drainage lumen

A substance measurement device includes: a container portion configured to receive a substance; a sensing device configured to measure a property of the substance related to at least one of a flow rate of the substance into the container portion, a level of the substance within the container portion, and a volume of the substance within the container portion; and at least one shield positioned within the container portion and configured to provide at least one of: a mechanical buffer between the substance entering the container portion and the sensing device; and an electrical shield between the substance entering the container portion and the sensing device.

A fluid container measurement system is disclosed. The fluid container measurement system is configured to suspend a load measurement assembly a distance above a support surface. The load measurement assembly houses a load cell and a measurement control circuit. The measurement control circuit is coupled to the load cell and configured to receive electrical signals indicative of a force imposed on the load cell. Electrical signals generated by the load cell indicative of the force exerted on the load cell can be used to measure the fluid container attached to the load cell linkage member.

A system for fall management is provided, including a bladder sensor configured to measure an amount of urine in a bladder of an individual; a controller configured to retrieve the amount of urine from the bladder sensor, determine if the amount of urine in the bladder has reached a threshold, and transmit a warning signal when the amount of urine reaches a threshold; a monitor, having a processor and a memory, configured to receive the warning signal transmitted by the controller; and alert a caregiver when the warning signal is received.

Urine collection systems and associated methods and devices are disclosed herein. A representative system can include a urine collection device, a flow control assembly configured to direct a urine flow from the patient to the urine collection device, and a urine measurement device including a first sensor and a second sensor. The first sensor is configured to generate first sensor data based on a weight of the container, and the second sensor is configured to generate second sensor data based on the urine flow from the patient to the container. The system can further include non-transitory computer readable media having instructions that, when executed by one or more processors, cause the system to perform operations comprising determining a first patient urine output based on the first sensor data; and determining a second patient urine output based on the second sensor data.

Systems, and methods for collecting discharged fluids. A fluid collection system (100) includes a fluid collection device (102) configured to collect fluid discharged from a user and a fluid collection container (106) configured to receive the fluid from the fluid collection device. The fluid collection system also includes a means for sensing (110) at least one of a property or status of the fluid collection system. The fluid collection system also includes a controller (112) operatively coupled to the sensor, the controller configured to communicate at least one of the property or the status of the fluid collection system to a computing device (114).

The systems and methods described herein combine both moisture and electromyograph (EMG) sensors in a single wearable garment, along with a suitable output device such as a smart mobile device or computer, to provide users with new and useful feedback that can significantly improve incontinence symptoms. The EMG provides feedback to the user specifically regarding the quality of pelvic floor muscle contractions, while the moisture sensor provides feedback about the end result of the subjects' incontinence. Each measurement device alone can also provide useful information and feedback to different population groups. Combining these two measurements provides unprecedented data to enhance the subjects' therapy in managing urinary incontinence.

An apparatus for measuring the flow rate of urine, including an encasement, configured to encase components of the apparatus; a receptacle bowl attached to the encasement, configured to be placed over a toilet bowl or seat, and direct fluid through a single point of exit to a fluid flow guide; the fluid flow guide, configured to transfer fluid from the receptacle bowl to an impeller; the impeller, configured to rotate along a rotation axis, wherein the impeller includes a plurality of blades, configured to receive the urine from the flow guide, and thereby rotate the impeller at a speed correlating with the flow rate of the urine; and an angular velocity sensor, configured to produce electric signals that correlate with the angular velocity or angular position of the impeller.
