Mobile diagnostic device "Sphere MD" is provided under the M.D. concept. The said device is designed for diagnosing diseases, monitoring a patient’s vital signs, express diagnostics in emergencies, and distant management of patients with chronic diseases (Virtual Hospital). It involves home use of in-hospital diagnostic methods with logging its results through different interfaces, allowing to process cardiological, endocrinological, therapeutical data separately. The device allows passing measured data into distributed data base with the use wired and wireless access networks interfaces. Simultaneously, it conducts primary health state diagnosis (evaluation of threshold limits). A patient independently makes needed health tests with the use of a required sensor. Upon completing this process all medical data is transferred to the cloud storage for further processing, analysis, archiving, and providing information for all parties concerned (patients, their relatives, doctors). Providing software as a service allows to integrate and analyze all medical data and prescriptions, compare them to existing medical history (cloud storage contains health tests results and medical records of all patients, ensuring their confidentiality), and to get a multilateral medical video consultations between patients and doctor. Herewith, it’s possible to create a set of characteristics, signs and symptoms that corresponds to particular course of treatment, which is appropriate to present condition of a patient. The software analyzes measured data, patients’ individual differences, categories of diseases. It allows to combine this information with the results of analysis in previous cases and Clinical guidelines.
