A system and urine sensing devices for and method of monitoring kidney function is disclosed, wherein the system and method can be used for the early detection of acute kidney injury (AKI). Namely, a kidney function monitoring system provides a portable urine monitor system that can provide real-time and continuous feedback about urine output and/or level of at least one urinary component (e.g., sodium). The kidney function monitoring system further comprises at least one urine sensing device, wherein the urine sensing device comprises a digital weight scale, a stand onto which a urine collection vessel can be positioned, and an interface between the digital weight scale and the stand that transfers the force of the stand and contents of the urine collection vessel to the digital weight scale. Further, the portable monitoring device comprises an adaptive and modular self-learning algorithm for the real-time assessment of AKI risk.

Here discloses a system for sensing bladder volume. The system includes at least one patch, a plurality of light emitters, a plurality of light sensors, and a process. The at least one patch is configured to attach to a human skin or a wearable garment at locations in proximity to an abdomen area. The light emitters are directed towards the abdomen area. The light sensors are configured to receive light signals that are emitted by the light emitters, reflected by human tissues, and transmitted through an abdominal wall. At least one of the light emitters or at least one of the light sensors is disposed on the at least one patch. The processor is configured to receive information of the received light signals and to predict a bladder volume based on the information of the received light signals.

An oxygen measurement device constituting an oxygen measurement system includes a urethral catheter and an oxygen sensor main body. The urethral catheter has a shaft in which a urethral catheter lumen that enables circulation of urine flowed in via a urethral catheter port from inside a bladder is formed; and has a hub in which a urine lumen that is provided at a proximal end of the shaft and communicates with the urethral catheter lumen is formed. The oxygen sensor main body is provided on the hub in a manner capable of being brought into contact with urine circulating in the urine lumen, and detects oxygen in the urine.

A monitoring system which constitutes an oxygen measurement system includes: an oxygen partial pressure calculation unit that calculates an oxygen partial pressure in urine based on an output signal from the oxygen measurement device; a monitor that displays the oxygen partial pressure calculated by the oxygen partial pressure calculation unit; and a display control unit that changes a format of display of the oxygen partial pressure displayed by the monitor according to the flow rate of urine acquired based on the output signal from the oxygen measurement device.

This voiding data display device (100) includes a voiding data display controller (5a) configured or programmed to display voiding data including a voiding date and time and a voided volume, a time data display controller (5b) configured or programmed to display data on a wake-up time and data on a fall-asleep time, and an analysis result display controller (5c) configured or programmed to display a result of analysis of the voiding data, and the voiding data display device is configured to display the voiding data, the data on the wake-up time, the data on the fall-asleep time, and the result of the analysis of the voiding data on a same window.

A device for monitoring body fluid discharge almost in real time is provided, the device includes a base, a motor, a catheter holder, and a liquid level sensor. The motor is fixed on the base and includes an output shaft. The catheter holder is connected to the output shaft and is rotatable relative to the base by the output shaft. The catheter holder includes a curved holding chamber with two openings containing a catheter. The liquid level sensor is disposed at one of the openings for detecting a liquid level of body fluid in the catheter and such level is recorded when a fully-filled catheter is automatically tipped and emptied into a collecting bag. A method for monitoring body fluid discharge using the device is also provided.

Systems, devices and methods for sensing physiologic data and draining and analyzing bodily fluids are described which are capable of sensing physiologic data based on sensors incorporated into a catheter adapted to reside in any of a urinary tract, gastrointestinal tract, rectal location, pre-peritoneal, pleural space or other body cavity. The devices aid emptying of the bladder, measure urine output and various urine parameters such as oxygen tension, urine conductance and urine specific gravity, monitor renal function, analyze urine parameters, including urine content, including the presence of infection, and track and/or control fluid administration.

A device for monitoring of an irregular liquid flow rate, such as urine or another bodily fluid from a catheterized patient, includes a measurement chamber having an inlet and an outlet, a liquid level sensor in the collection vessel, a closure, and a control unit. The chamber is configured to allow liquid to enter through the inlet and leave through the outlet, respectively. The closure opens and closes the outlet in response to signals from the control unit. The liquid level sensor provides a signal to the control unit when liquid in the vessel attains a first preset volume.

Embodiments disclosed herein are directed to apparatus and methods for automatic fluid flow system connectors. The system generally includes a load cell interface coupled to a console and a ring connector coupled to a fluid collection system. The ring connector can be releasably engaged with the load cell using an engagement structure such as a latch, locking arm, or spring clip mechanism. The ring connector and load cell can include electrical contacts configured to engage along an axis that extends perpendicular to a surface that the electrical contacts are disposed on. Advantageously, reduced wear on the electrical contacts should extend the usable life of the system.

Systems, devices and methods for draining and analyzing bodily fluids, pressures and assessing health are described where a drainage system generally comprises an elongate catheter having a first end and at least one opening in fluid communication with a catheter lumen, a drainage tube having a drainage lumen in fluid communication with a second end of the catheter, a fluid reservoir in fluid communication with the drainage lumen, and a pressure sensing membrane in communication with a pressure lumen defined through the catheter. The system also includes a pressure sensor coupled to the pressure lumen and configured to receive an intra-abdominal pressure signal from the pressure sensing membrane via the pressure lumen, and a controller in communication with the fluid reservoir and the pressure sensor. The controller is configured to determine an abdominal perfusion pressure based on the intra-abdominal pressure and a mean arterial pressure received by the controller.
