The present application relates to an electronic wetness-sensing absorbent article and related methods. The electronic wetness-sensing absorbent article includes a flexible waterproof thin film; at least two mutually separated and insulated flexible electrodes disposed on one surface of the flexible waterproof thin film; a water-permeable braided fabric layer; and an absorbent layer disposed on the other surface of the flexible waterproof thin film, located between the flexible waterproof thin film and the water-permeable braided fabric layer, and adapted to absorb a liquid entering from the water-permeable braided fabric layer. The flexible waterproof thin film, the flexible electrodes, and the liquid contained in the absorbent layer form a non-polar variable electrolytic capacitor. The wetness state of the electronic wetness-sensing absorbent article is obtained by detecting the capacitance value of the variable electrolytic capacitor and change thereof.

The present invention relates to the diagnosis and treatment of urinary incontinence. The diagnosis and treatment involves the use of a multiple sensor-enabled catheter capable of providing real-time data regarding the patient's physiology, such as urinary flow and muscular function of the bladder sphincter, as well as the position and movement of the catheter within the patient.

A non-transitory computer-readable medium storing a computer program, an information processing method, and information processing apparatus that displays an index suitable for grasping a status of kidneys. The computer program causes a computer to execute processing of acquiring urine information including urinary oxygen tension, calculating a renal status index on the basis of the urine information, and outputting the renal status index. The urine information includes a urinary output, a urine flow rate, urinary color, urine absorbance, a urinary sodium amount, or a urinary creatinine amount, in addition to the urinary oxygen tension. The renal status index is an index related to an estimated value of renal artery blood flow, the urine information includes the urinary oxygen tension and the urine flow rate, and the renal status index is calculated on the basis of the urinary oxygen tension and the urine flow rate, by using a predetermined algorithm.

Systems, devices and methods for draining and analyzing bodily fluids and assessing health are described and generally comprise a drainage tube in fluid communication with at least one opening near or at a distal end of a catheter, a pump in fluid communication with the drainage tube and configured to apply a negative pressure to the drainage tube, and a valve configured for unidirectional flow and in fluid communication with the drainage tube. A controller is configured to actuate the pump to apply the negative pressure for clearing an airlock and to monitor a urine output from the patient over a first predetermined period of time above a urine output threshold and over a second predetermined period of time below the urine output threshold. The controller may determine a risk of acute kidney injury if the urine output below the urine output threshold exceeds the second predetermined period of time.

A urine collector includes a receptacle formed of a water soluble material, which may be a bioplastic, and has a receiving volume for collecting urine therein defined by its shape. The urine collector is flushable and is configured to float in toilet water for use by a user to collect urine. A threshold volume indicator positioned at a level corresponding to a predetermined threshold volume extends around the circumference. The upper interior surface changes color upon contact with urine, a color change of the upper interior surface indicating that the urine collected is greater than the predetermined threshold volume. A patch may be included in the interior surface to detect the presence and/or level of component in the urine indicative of a condition or infection, e.g., ketone, glucose or hormone levels. The urine collector may include a substrate that facilitates separation from a stack of urine collectors.

In some examples, a system is configured to determine a non-cerebral autoregulation status value of a patient using machine learning. In some examples, processing circuitry of the system is configured to determine, using a neural network algorithm that has been trained via machine learning training, an individualized adjustment value that is individualized for the patient, including inputting physiological data associated with the patient. The processing circuitry may determine a non-cerebral autoregulation status of the patient based on a cerebral autoregulation value of the patient based on the non-cerebral autoregulation status value of the patient and the adjustment value.

The invention is an apparatus and method for measuring the flow rate of a liquid through a conduit. The apparatus is based on a flow rate meter which is adapted to accurately measure the volumetric flow rate of a liquid using a simple, cost and energy effective, and accurate method using only one temperature sensor. The method is based on applying a pulse of thermal energy to the flowing liquid and measuring the temperature increase as a function of time and energy input. By comparing these measurements to a calibration table made by performing similar measurements for known flow rates, the rate of flow can be determined. One application, which will be described to illustrate the features of the method and apparatus of the invention, is measurement of the flow rate of urine excreted by a catheterized patient.

Disclosed herein is an automated urinary output monitoring system including urine collection assembly that includes a first drainage tube coupled between a urinary catheter and an interim container, and a second drainage coupled between the interim container and a final container. A scale measures the weight of urine collected in the final container and a display depicts the volume of urine collected in the final container. A vacuum pump can be coupled with the final container to draw urine from the interim container into the final container, and an air vent can isolate the patient from the vacuum within the final container. The system can be configured to wirelessly transmit urine volume data to an external computing device. A gyroscope can be coupled with the scale to determine the orientation of the scale. Logic of the system can calculate urine volume and correlate with the time of day.
