Havano B. Methods and means of assessing the human condition in medical cyberphysical systems

The thesis is devoted to the solution of the actual scientific and technical task of development of methods and means of assessing the human condition on the basis of processing of the measured vital indicators by sensors in medical cyberphysical systems. The introduction substantiates the relevance of the topic of dissertation research, formulates the purpose of research and scientific and technical tasks necessary for its achievement, shows the connection of research with scientific programs and topics, presents the scientific novelty of the results, their practical value and personal contribution of the applicant. approbation of work results. The first section analyzes the existing approaches to the construction of medical cyberphysical systems, namely their structure and architectural solutions of server software. The analysis showed that in the design and implementation of medical CPS, it should be borne in mind that medical data is big data, and their processing should take place in parallel. According to the analysis, the architectural and functional requirements for medical CPS are determined. The analysis of the principles of data storage in medical CPS is carried out. The tasks of assessing the human condition are set. The second section proposes means of information processing in medical cyberphysical systems, the result of which is to assess the human condition. A model of information processing in medical CPS is proposed. To differentiate the means of information processing into separate independent logical elements, the proposed model of information processing is based on a microservice architecture, where each tool is in the form of a microservice. A method for detecting critical events in the medical cyberphysical system has been proposed, which is based on one of the most widely used EWS manuals and an aggregated assessment of human vital signs. An algorithm for classifying patients and an algorithm for diagnosing diseases are proposed. In the third section, according to the proposed model and means of information processing, the structure of the medical cyberphysical system is proposed. From this structure the offered architectural-information model of information processing which is based on model of data processing which is based on microservice architecture with use of API of the gateway is allocated. The description of functional elements of architectural-information model of information processing is carried out. Clear interaction of functional elements in the architectural-information model of information processing is a means of assessing the human condition in the medical cyberphysical system. The business logic of medical CPS is described, namely the system of connections and dependencies of business data elements and rules of data processing. The fourth section describes the implementation of server software for medical cyberphysical system, which is based on the proposed architectural and functional model of information processing. Implemented a means of authentication and authorization of users; background task declaration service; event notification tool using 2 communication channels; a means of detecting critical indicators, which is based on the proposed method of detecting critical indicators; a mean that includes adapted algorithms for patient classification and disease diagnosis; means of processing and aggregation of measured indicators. The principles of the organization of data storage in the realized medical cyberphysical system, with use of storages of different type, depending on need of means of information processing are described. The principle of operation of the medical cyberphysical system "HealthyLungs" is described, in which the proposed methods, means and model of information processing were implemented.
