The present invention is directed to a toilet that includes a slanted fill tube with an optical proximity sensor positioned on or within the inner surface of the fill tube. The optical proximity sensor includes an incoherent light source and a photodiode. The optical proximity sensor as disclosed herein detects small changes in volumes added to a toilet bowl. Consequently, small volumes of excrement that are deposited in the toilet bowl by a user may be detected with greater accuracy. In some embodiments, information about the volume of urine or feces deposited into the toilet bowl is recorded and calculated by a processor. Other sensors, including a toilet bowl water level sensor and a gas sensor may collect data in combination with the optical proximity sensor to provide more complete information about the user's health.

A urinary catheter having a sensor or indicator affixed therein in a location that will be in the flow of urine when catheter is in use. The indicator comprises an electrolytic wicking material having an anode and a cathode thereon separated across the gap. The wicking material may be paper. The indicator further includes an output transducer positioned and connected relative to the anode and cathode such that a circuit which energizes the output transducer is created when urine flows. The indicator is configured to generate an output signal received at a remote location so that a medical practitioner can monitor proper usage of the catheter. There may be multiple anode/cathode pairs connected in series or parallel to increase voltage or current. Also, a capacitor and/or an antenna may be provided for the output transducer to boost the output signal.

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. The shaft also includes a gas permeation suppressing part that suppresses gas permeation into the urethral catheter lumen by way of the shaft.

A urine measurement system (101) comprising an oil mixture arranged in the luminal space of the measurement system. A method for inhibiting impairment of functionality and measurement accuracy in a urine measurement system comprising applying an oil mixture to the inner surfaces of the urine measurement system. Use of an oil mixture in treatment of luminal surfaces of a urine handling system.

A method to protect kidneys of a patient undergoing cardiac surgery patient including: administrating a diuretic to the patient to increase urine output of the patient during cardiac surgery, wherein the diuretic is administered during the cardiac surgery; anesthetizing the patient with a general anesthetic during the cardiac surgery; infusing an intravenous liquid into the patient during the cardiac surgery; monitoring a rate or amount of urine output of the patient during the cardiac surgery, and automatically adjusting a rate or amount of the intravenous liquid infused into the patient to achieve or exceed a target urine output during the cardiac surgery.

The present invention is directed to a toilet which is a medical device and which includes multiple sensors and mechanisms for analyzing health metrics that may include biomarkers. The toilet is in communication with a computer processer that is programmed to evaluate the validity of collected health metrics. One set of metrics may inform the validity of another set of metrics. Each data point within the multiple health metrics is assigned a weight value that is an indicator of its validity. Data points may be excluded from calculations if deemed to be invalid. Data points may also be flagged as requiring additional information about the user to determine its validity or interpretation. Methods of using the toilet to assess the health status of a user is also disclosed.

A system for monitoring incontinence in one or more subjects comprises display means; input means operable by a user; one or more transmitters, each transmitter being associated with one or more subjects being monitored; the one or more transmitters being configured to transmit signals containing continence-related data for the one or more subjects, wherein the continence-related data has been obtained over time from a continence sensor associated with an absorbent article worn by each respective subject; a receiver unit configured to receive signals from the one or more transmitters; and processing means in communication with at least the receiver unit, the processing means including a display processor configured to process the received signals and communicate display information to the display means for display of a visual representation of continence-related information derived from continence sensors in the absorbent articles worn by the one or more subjects being monitored. The system may include a volume estimator and means for communicating to a carer a risk of wetness leakage based on e.g. an estimated volume of wetness and e.g. a pad type. Pad type may be communicated to the system automatically by way of a pad type indicator associated with the pad and/or pad/sensor combination.

The present invention relates to an urine specimen collection system in which the urine sample to be taken for the laboratory tests, can be collected without interrupting the patient while urinating. Present invention will transfer certain amount of urine into the specimen container by collecting the urine of the patient collected during the urination speed test. Thus, the specimen acquired from the urination speed test can be used in the laboratory tests. System will transfer the urine of the patient into a specimen container automatically by steps applied during the regular urination process and immediately after this process. System then will perform the cleaning of the urinated reservoir.

This invention provides a dynamic urine monitor. The dynamic urine monitor comprises a case, inside which is equipped with a urine collection device, a pipeline for flowing the urine into the urine collection device, and a measurement system for dynamically measuring the urine. The measurement system comprises a weight measurement subsystem, a density measurement subsystem, and an outlet-inlet module. The weight measurement subsystem comprises a weight sensor and a weight information ADC; the weight sensor dynamically measures the urine weight of the urine collection device. The density measurement subsystem comprises a density sensor and a density information ADC. The density sensor dynamically measures the urine density and it is serially connected with the upstream pipeline of the urine collection device. The outlet-inlet module is used to exchange the information of the weight information ADC and with density information ADC with outside.

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.
