System for predictive monitoring of the deterioration of patients' health status using temporal modeling of electronic patient records

Abstract

A system for predictive monitoring of patient deterioration by temporal modeling of electronic health records, the system comprising: a housing defining an enclosed volume; a plurality of input interface units arranged on the housing and configured to receive electronic health data including physiological signals, laboratory measurements, and clinical observations from external medical devices; an analog-to-digital converter unit electrically connected to the input interface units and configured to convert received signals into digital data streams; a signal conditioning unit operationally connected to the analog-to-digital converter unit and comprising filtering, normalization, and scaling circuits configured to standardize heterogeneous data into a uniform data representation;a temporal buffer unit consisting of a plurality of storage registers arranged in a sequential configuration, wherein the temporal buffer unit is configured to store time-indexed data samples over a predefined observation interval to generate a temporally ordered data structure; a synchronization unit configured to generate clock signals and align incoming data streams into synchronized timeframes before storage in the temporal buffer unit; a matrix transformation processor electrically coupled to the temporal buffer unit, wherein the matrix transformation processor comprises parallel arithmetic circuits, including multipliers, adders, and accumulators, arranged to perform weighted transformations on the temporally ordered data structure to generate temporal feature representations;a storage unit with non-volatile memory elements configured to store weighting parameters corresponding to the temporal characteristics of physiological data; a sequence evaluation unit operationally connected to the matrix transformation processor, comprising comparator circuits, gradient calculation circuits, and threshold evaluation registers configured to determine temporal deviations, rate-of-change characteristics, and cumulative variations indicative of a deterioration in the patient's condition; a decision output unit configured to generate a deterioration prediction signal based on the outputs of the sequence evaluation unit, the decision output unit further comprising a display unit, an audible alarm unit, and a communication unit for transmitting alarm signals;and an energy management unit configured to supply regulated electrical power to all units within the enclosure, wherein the system is configured to continuously process temporally ordered electronic health data to generate predictive indicators of deterioration in patient condition in real time.
