A monitoring device for monitoring the fluid balance of an animal or human body. The device includes a body weight sensor for continuously or periodically weighing the body, a fluid delivery device for providing a controllable supply of fluid to the body, a urine output sensor for determining the urine output of the body, a processor. The processor is adapted for determining a total fluid outtake of the body and a fluid outtake due to perspiration and respiration by taking a signal provided by the body weight sensor and a signal provided by the urine output sensor into account, and providing a control signal to the fluid delivery device to regulate a volume, flow velocity or flow rate of the fluid delivered to the body, so as to maintain a predetermined fluid balance in the body.

A patient monitor and a separate user interface for the patient monitor, adapted to communicate with one another over a communication pathway. Both the patient monitor and the separate user interface are able to independently check the status of the communication pathway, and visually indicate this status.

Described is an apparatus for inline urine analysis comprising a control unit and at least one image capture unit comprising an image sensor and an optical assembly. The apparatus is configured to be coupled with an indwelling urinary catheter or conduit leading from the catheter. Embodiments of the apparatus comprise a dispenser configured to dispense inert or reactive matter into the urine stream to aid in the analysis of properties of the urine and an illumination device configured to illuminate the urine stream. Also described is a system comprising at least one of these apparatuses and at least one image analyzer unit operatively connected to it. The image analyzer unit comprises a processor and software adapted to analyze the captured images to derive information therefrom relating to identification of properties of the urine and/or objects of interest in the urine stream. Embodiments of the system may comprise other peripheral devices.

An analytical toilet comprising a bowl adapted to receive excreta; one or more conduits for transporting a sample from the bowl; one or more fluid sources in fluid connection with the one or more conduits; and one or more microfluidic chips, comprising at least one fluid inlet; at least one fluid outlet; and a sensor configured to detect at least one property of an excreta sample is disclosed.

A method for detecting urination includes (a) obtaining sensor data S, which is continuous data according to the passage of time and generated by the movement of a measuring device; and (b) filtering the sensor data S as valid data related to urination among the sensor data S obtained in (a) by using a valid data filtering module of the measuring device according to a preset method. The filtering includes filtering the sensor data S obtained when a distance between a sensor installed in a space provided with a urinal or a toilet seat and the measuring device is within a preset distance, as the valid data.

A system and method for collecting operation data associated with a medical apparatus including an internal device implanted in a subject and an external device that is magnetically-coupled to and drives the internal device. The medical apparatus may be monitored to obtain raw data associated with the operation of the medical apparatus and one or more calculations may be performed on the raw data, wherein the raw data and/or calculated values may be associated with voiding frequency and voiding volume of the subject. A report may be generated from the raw data and/or calculated values. In addition, one or more signals may be sent to the external device and/or a docking station, or communicated by other means, to indicate to the subject that the operation of the medical apparatus should be altered.

A urodynamic investigation apparatus for receipt of urine from a bladder is provided. The apparatus is characterized by a tubular element, first and second fittings, and a sleeve element, for select passage of urine there through, within the tubular element. The tubular element is characterized by opposing first and second end portions, and a port. The fittings are adapted to be received by the opposing end portions of the tubular element so as to delimit an apparatus chamber. The sleeve element, suspended between the fittings within the chamber, has collapsed and open configurations. The collapsed configuration is indicative of a no urine flow condition, and the open configuration indicative of a urine flow condition, with the sleeve element urine flow condition being a function of pressure applied to the chamber via the port of the tubular element.

Embodiments herein include systems and methods for detecting, predicting and/or assessing acute kidney injury. In an embodiment, a monitoring system to detect acute kidney injury is included. The monitoring system can include a sensor circuit configured to collect renal data including at least one of systemic renal data, direct renal data, urinary tract data, and renal-relevant extracorporeal data. The monitoring system can also include a memory circuit to store collected renal data, an evaluation circuit to assess renal status, and a telemetry circuit. The evaluation circuit can determine whether acute kidney injury has occurred or is likely to occur by comparing the renal data to at least one of threshold values, personal historical values, patient population values and patterns indicative of acute kidney injury. The evaluation circuit can initiate a warning notification if acute kidney injury has occurred or is likely to occur. Other embodiments are also included herein.

A ureteral catheter includes a drainage lumen having a proximal portion configured to be positioned in at least a portion of a patient's urethra and/or bladder 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 includes a retention portion for maintaining positioning of the distal portion of the drainage lumen. The retention portion includes a plurality of sections, each section having one or more openings on a sidewall of the retention portion for permitting fluid flow into the drainage lumen. A total area of openings of a first section of the plurality of sections is less than a total area of openings of an adjacent second section of the plurality of sections. The second section is closer to a distal end of the drainage lumen than the first section.

An artificial bladder system including an implantable bladder, a valve, a number of sensors, and an alert mechanism. The implantable bladder includes an outer wall forming a chamber for collecting urine of a user, the outer wall including inflow openings and an outflow opening. The valve is integrated with the outflow opening to selectively allow urine to flow from the chamber through the outflow opening. The sensors are configured to detect a urine level in the chamber. The alert mechanism is configured to generate a sensory output to alert the user that the bladder should be emptied upon detection of the urine level in the chamber by one of the sensors.
