FIELD: medicine.
SUBSTANCE: group of inventions relates to medicine, namely to a multifunctional portable device for recording and analyzing vital signs and a method for recording and analyzing vital signs using a multifunctional portable device. The device consists of a functional unit, a software unit. The functional unit is connected by two-way communication with the client device unit over a wireless network. The functional unit contains a sensor unit, an ECG module unit, an RR module unit, a SpO2 module unit, a temperature module unit, a microcontroller unit and a power supply unit with a battery. The power supply unit is connected to the four blocks of the functional unit by one-way outgoing communication, and to the microcontroller unit by two-way communication. The sensor block contains a block of electrodes, a block of LEDs, a block of photodetectors. The electrode block consists of an RA electrode block, an LA electrode block and an LL electrode block. The LED block consists of an LED block and an IR LED block. The photodetector unit consists of an IR photodetector unit t, a photodetector unit and an IR photodetector unit. The sensor unit is equipped with a button unit. The ECG module unit consists of three op-amp units with negative and positive input, three ADC units, three interference filter units and a digital transmission control unit. The block of the RR module contains an impedance measurement unit, an ADC unit, an interference filter unit and a digital transmission control unit. The SpO2 module unit consists of a pulse generation unit, a digital transmission control unit, a background light compensation unit, an interference filter unit and an ADC unit. The temperature module unit contains an op-amp unit, an ADC unit, an interference filter unit and a digital transmission control unit. The microcontroller unit consists of a wired digital transmission control unit, a settings module unit, a microprocessor unit, a memory unit, a firmware unit and a wireless transmitter unit. The client device unit contains an Internet connection unit, a microprocessor unit, a software module unit, a data input unit, a memory unit, a wireless transmitter unit, a display unit and a power supply unit with a battery. The program unit contains an Internet server unit, a software module unit and a memory unit. In this case, the blocks are respectively interconnected. When performing the method, ECG, RR, SpO2, and temperature data are recorded. A preliminary analysis is performed, namely, the following parameters are calculated: the values of the intervals PQ, QRS, QT, QTc, the level of displacement of the ST segment relative to the contour line, heart rate HR, respiratory rate RR, blood saturation SpO2, body temperature T, heart rate variability HRV, pulse wave propagation velocity. The input data is visualized using the display unit in the form of graphical data, and the analysis results are displayed in the form of numerical values. If there is Internet access, they communicate with the program unit using the Internet connection unit and transmit the received signal to it. The suitability of the signal on the server block on the Internet is assessed using the software module block and return information about the signal quality to the software module block of the client device block, in the absence of Internet access, the suitability of the signal is evaluated using the software module block of the client device block in isolation. If there is an unsuitable signal, using the software module of the client device unit, commands for ECG, BDD, SpO2, temperature module blocks are transmitted to the microcontroller unit settings module block and the operating mode of the module blocks is adjusted to obtain the best quality, the sensitivity of the ADC blocks, the measurement frequency, and/or the parameters of the interference filter blocks are changed. If the signal quality is higher than acceptable, vital indicators are evaluated using the software module block: determining the presence or absence of a pulse deficit, the Hindelbrant index, calculating the degree of relative bradycardia, isolating pathological patterns of ECG and photoplethysmography data, comparing the calculated values with the normative values, taking into account the age and gender of the person, storing the values obtained in the memory block; then, using the server block on the Internet, the results of the analysis of input data are transmitted to the memory block of the client device block, displaying the received data on the display block of the client device block.
EFFECT: registration and analysis of vital signs are provided with the help of a multifunctional portable device for assessing human health, reducing the time spent from the appearance of clinical symptoms to diagnosis and choice of treatment tactics is achieved.
