The invention discloses a multi-dimensional night urination behavior monitoring system based on rhythm features, and relates to the technical field of biomedical signal processing, and the system specifically comprises a data acquisition module, a rhythm feature extraction module, a urine volume dynamics modeling module, a clustering monitoring module and a real-time feedback module; collecting individual data in real time through IoT equipment and preprocessing the individual data; calculating a nocturnal urination frequency index, a nocturnal urination time concentration ratio, a urination interval rhythm variation coefficient and a deviation index based on the individual data, and performing rhythm feature extraction; performing quadratic polynomial least square fitting on the night accumulated urine volume, and calculating a urine volume acceleration index by using an obtained second derivative to quantify a urine volume generation trend; the method comprises the following steps: constructing and preprocessing a night urine multi-dimensional digital phenotypic vector matrix, fitting a Gaussian mixture model based on an expectation maximization algorithm of a Bayesian information criterion, automatically mapping individuals into four types of subtypes according to cluster center features, and outputting individual subtype labels and confidence coefficients; and obtaining a comprehensive risk score through normalized risk assessment.

The utility model relates to medical appliance technical field discloses a kind of non-invasive automatic urination recording devices for nocturia patient, including collection bucket, the top of the collection bucket is engaged with fairwater, the middle part of the fairwater is equipped with drainage port, the bottom end of the drainage port is fixed with drainage tube, the surface of the drainage tube is equipped with flow sensor and check valve, the bottom of the collection bucket is equipped with collection cylinder with screw thread, the outside of the collection bucket is equipped with handle, control module, power and output module are respectively equipped in the inside of handle;The utility model can accurately detect the amount of urine discharged by the flow sensor, and the control module records the time and urine volume and stores them to the SD card. The output module generates a hourly urination report, and the data accuracy is higher. The collection bucket is shaped like a large upper and small lower, which is beneficial to collect urine of patients of different genders and is not easy to cause urine spillage.

Nocturia has been defined as the need for an individual to wake up one or more times during the night to void. Further, Nocturia detection also requires analysis of sleeping pattern of the person. In such cases a lot of assumptions are made when the person is not in bedroom during nights. A method and system for detection and validation of Nocturia in the person has been provided. The system is utilizing a statistical based analysis, a rule based analysis, a machine learning based analysis and analysis of sleeping pattern of the person to detect and validate Nocturia. The system ensures that the person is not disturbed in his / her daily activities. Further, the processes deployed in the system are completely un-supervisory in nature meaning it does not have the dependency of needing to have trained machine learning dataset.
