Description

The invention relates to medical equipment and is intended for registration, control and remote transmission in wearable mobile devices of such vital health indicators as: electrocardiogram (ECG), heart rate (HR), activity, detection of falls, detection of a wide range of arrhythmic disorders and disorders conductivity, heart rate variability parameters, blood saturation (blood oxygen saturation SPO2), temperature.

Wearable wearable systems for monitoring patient health indicators are today becoming one of the most promising areas for the development of digital medicine, which is the future. It is on the basis of constantly monitored human vital parameters that systems of personalized and preventive treatment, solutions for monitoring the condition of the elderly and chronically ill people, etc. are being created today.

At the same time, the problem of a large number of underexamined patients with cardiovascular and pulmonary diseases and the lack of convenient and easy-to-use means of body screening for Covid infection make it urgent and practically significant to create systems that would combine the possibility of remote online monitoring at the same time. several important vital signs of health with a compact design and the possibility of self-connection.

This problem is especially relevant for the class of wearable body recorders of physiological health parameters, which, although they have higher clinical measurement accuracy than fitness bracelets, are inferior to the latter in terms of monitoring the number of vital health indicators.

All the currently available variety of wearable devices for remote monitoring of health is usually limited to devices for measuring pulse, heart rate (HR), or recording and subsequent transmission for further analysis of the electrocardiogram (ECG) signal. Those. the functionality of mobile wearable devices is limited mainly to the analysis of the ECG and the parameters calculated from it.

For example, Holter heart monitors are known ["Personal telemedicine", O.Yu. Atkov, Practice, M, 2015, "Medicine in the age of the Internet", A.V. Vladzimirsky, Eksmo, 2020], which are usually used for long-term continuous recording of the patient's ECG signal. However, the data recorded by the Holter monitor reflects only cardiac activity and at the same time become known and can be analyzed only a few days after the period of their registration is over and the data can be transferred to a remote computer. Online analysis of ECG in Holter monitors is not possible, since ECG data is only recorded and not immediately reported. In addition, Holter monitors are very difficult to install sensors and their placement on the patient's body is carried out only by medical staff, which makes their regular home use problematic. At the same time, heart monitors are very inconvenient to wear because of the numerous wires on which numerous interference signals are induced, causing artifacts that reduce the reliability of data collection in conditions of natural motor activity.

It is important to note that the fundamental disadvantage of the known wearable devices is that only one regulatory system in the body, in particular, the cardiac one, is taken into account for assessing the state of health and predicting homeostasis. However, taking into account only one indicator strongly depends on side and random factors and requires additional consideration of the individual characteristics of the autonomic regulation of each person, since not a single physiological system and function of the human body is decisive [“The relationship of the cardiovascular and respiratory systems as an innovative method assessment of the functional capabilities of the body of athletes "Vanyushin Yu.S., Minnibaev E.Sh. Bulletin of the Kazan State Agrarian University, No. 3 (13), 2009, volume 4, pp. 150-152]. Therefore, in order to increase the reliability of the results of assessing the state of health, it is desirable to additionally use in the device the values of parameters and other regulatory systems - respiratory (respiratory), oxygen saturation in the blood, bioelectrical regulation of the central nervous system and, accordingly, use additional biosensor sensors.

There is a whole group of wearable mobile devices that take ECG and through its signal indirectly determine other physiological parameters. For example, a patent of the Russian Federation for a utility model No. 162018, IPC A61V 5/00, publ. 05/20/2016 recording ECG signals from one or two standard or modified leads by applying a device with built-in metal electrodes to the fingers of the left and right hands, RF patent for utility model No. 94141, IPC A61V 5/0402, publ. 05/20/2010, US patent No. 9 839 363, publ. December 12, 2017

The advantage of such devices is the absence of patient cables and the relative ease of use available for use at home. However, this class of cardiac recorders has a number of fundamental drawbacks that hinder their practical application: the ECG signal is taken only occasionally, only at the moment of applying the fingers or the device itself, i.e. not constantly in real time, and, therefore, is not able to monitor the state of health during sleep and timely detect the onset of critical health deterioration; the quality of the recorded signal is low due to artifacts caused by mimicry and tremor of muscle tissue during finger pressure, which reduces the reliability of the recorded data. The functionality of the device is also limited to recording the ECG signal and heart rate variability.

More advanced devices are also known, for example, a wearable diagnostic device (NDU) for remote continuous monitoring of an electrocardiogram, RF patent No. 2675752, IPC A61B 5/0432, publ. 12/24/2018 bul. No. 36. The device contains a housing fused into a shell of a flexible biocompatible material, it integrates a rechargeable battery, a biopotential amplifier connected to an electronic ECG processing unit with an analog-to-digital converter, an accelerometer, a memory for storing accumulated ECG information, a wireless transceiver, adhesive ECG- electrodes, charging dock. The shell of the body is made with elongated sections on the sides, button connectors are fused into them for connection with the button part of the ECG electrodes. A membrane keyboard is installed on the upper part of the case, the keyboard has an on-off button and LED indicators for displaying the operation of the NDU. The device allows for both screening and long-term remote monitoring of cardiac parameters in real time, including in the modified CM-5 ECG lead. However, the functionality of this device in terms of measuring pulse wave and SO2 is still limited, and the design characteristics are also disadvantages - insufficient flexibility of the silicone shell of the case and poor ergonomics, the possible occurrence of contact dermatitis due to contact of the user's skin with electrical contacts on the bottom surface devices, the inability to use standard chest belts due to non-standard distance between the connectors, the presence of a docking station for the charger.

A further direction for improving known developments, due to the importance of multi-parameter control, has become a natural increase in the size of the adhesive patch (patch) in order to secure a plurality of ECG sensors and functional state sensors.

One such solution was presented by the French company Scaleo Medical. The company's product, My Angel VitalSigns, is a wearable device that sticks to the chest with an extended triangular adhesive backing. The My Angel VitalSigns device is designed to track electrocardiogram (3-lead ECG), SPO2, body temperature around the heart, heart rate and respiration, and blood pressure. The system is built in such a way that in case of any signs of deterioration in health, which is assessed by these parameters, it immediately sends a signal to the user's smartphone and addresses included in a specialized list. The system consists of two parts - an electronic module containing all the sensors necessary to provide measurements and a data transmitting part, and stickers with a pocket in which the battery is located and where the electronic part of the system is inserted. The disadvantage of the system is the complexity of the design, large dimensions, the uniqueness of the design dimensions of the patch and the complexity of the availability of consumables. But the most important thing is that, in the center of the chest, the number of capillaries drops sharply (more than 50%), which leads to a significant decrease in peripheral blood flow. As a result, the measurement by the method of photoplethysmography on the reflection of the pulse wave, blood saturation and blood pressure becomes unstable or even impossible.

The wearable system and the method for collecting physiological signals also have a similar disadvantage, US patent No. 2019/0099132, publ. 04/04/2019.

One of the main disadvantages of this type of device is the insufficient level of blood filling of the vessels in the chest area, which creates problems for stable measurement by photoplethysmography of pulse wave reflection, blood saturation and blood pressure. In addition, additional disadvantages are large dimensions, a patch of large sizes and original configurations, which creates problems with the choice of consumables and increases the cost of devices, complicates the production technology and is unergonomic and inconvenient for regular use.

Thus, the main significant drawback of the known analogues is the uncertain operation and low reliability of the results of measuring blood saturation SPO2 and pulse wave when measuring by reflection photoplethysmography in the chest area, which is determined primarily by low peripheral blood flow in this area.

Another direction for improving developments in multifunctionality was the implementation of original designs in smaller sizes, in particular, domestic devices "Kardiobit", RF patent for the invention No. 06/22/2018, bul. No. 18 and a mobile device for remote health monitoring "TmT", RF patent for industrial design No. 127010, publ. 08/19/2021, bul. No. 9.

The most advanced device potentially suitable for monitoring a significant number of controlled physiological parameters is the device for remote continuous monitoring of the electrocardiogram "Kardiobit", which is selected as a prototype. It contains a housing and three external flexible ECG electrodes, made with spatial separation of the biosignal pickup and electrical connection zones, and provided with a layer adhesive to the body, two of which are connected directly to push-button connectors located at the remote ends of the lower surface of the housing. The third flexible ECG electrode, if necessary, can be connected by a conductor to the female connector on the side surface of the housing. Button connectors of two ECG electrodes are symmetrically spaced at a distance of 45 mm from each other with the possibility of placing an additional biometric sensor between them. The female connector on the side of the housing is sealed and has a group of additional contacts for wired connection of the signal processing electronics, for example, to an external charger, or to an external computer, or a smartphone, or a tablet, or to additional external ECG electrodes.

An additional biometric sensor for recording changing physiological parameters is located in the middle between the push-button connectors on the lower surface of the case, which allows, synchronously with the ECG signal, to obtain additional data on blood oxygen saturation, stress level, body temperature, electrically connected to the electronic signal processing unit.

In one embodiment of the prototype, an additional biometric sensor on the lower surface of the housing is made in the form of a group of emitting and photoreceiving photoplethysmographic sensors operating in reflection mode. Potentially, this makes it possible to theoretically measure blood oxygen saturation, record a pulse wave, and use the delay between the ECG R-peak and pulse wave systole signals to estimate blood pressure without using inflated cuffs.

However, although the prototype makes it possible to obtain more data on the state of health, it has the same fundamental drawback that does not allow in practice to implement the possibilities stated in the patent for stable and reliable measurement of blood oxygen saturation and pulse wave by the method of photoplethysmography for reflection in the chest area. The reason is the same - the number of blood vessels on the chest is significantly lower (by 40 - 50%) than in commonly used areas (finger in the light, earlobes, etc.).

Due to a significant weakening in the thoracic zone of peripheral blood flow, the reflected signal of the photoplethysmogram inevitably falls, especially for infrared radiation. This drop in signal has to be compensated for by amplifying the electrical signal, but this leads to a critical increase in the background noise of the photodetector, and the signal-to-noise ratio at the information output becomes so low that the device cannot perform its functions stably and reliably or completely stops working [Respiratory monitoring: pulse oximetry , capnography, oximetry. Nevsky dialect. St. Petersburg: BINOM Publishing House. 200 s.].

In addition, the location of the photoplethysmography sensors on the underside of the device makes it impossible to use the sensors when wearing the device on a standard chest belt.

In addition, the presence of a flexible display and control panel is technologically excessively complex and significantly increases the cost of production (approximately increases the cost by 20%), and also increases the overall dimensions of the device in height (at least by a few millimeters).

The temperature sensor, when located in the chest area, fundamentally gives temperature values that are different from the generally accepted ones, which forces constant additional calibration, which causes inconvenience and complicates its practical use. In addition, the use of a temperature sensor is not possible when using a chest belt.

The technical objective of the claimed invention is to eliminate the above drawbacks in the prototype, namely:

1. Improving the stability and reliability of registration and measurement in a wearable mobile device in the area of its placement on the chest synchronously with the ECG of the pulse wave, and blood oxygen saturation SPO2;

2. Simplifying the design, improving manufacturability, ease of use, reducing the overall thickness, reducing the cost of manufacturing the device and creating conditions for import substitution;

3. Creating the possibility of attaching the device to the body using standard chest belts without compromising functional performance;

4. Temperature measurement without the need for permanent calibration.

The solution of this technical problem is achieved by the fact that in the wearable mobile device for remote monitoring of multiple physiological parameters (hereinafter referred to as the device), which contains a plastic case, on the surface of which a photoplethysmographic biometric sensor is placed, optical outputs of LED indicators that display the modes and operating states of the device, a functional tactile the “Symptom” button and the power on/off button, while on the bottom surface at a distance of 45 mm from each other there are two push-button connectors for connecting external flexible ECG electrodes, which are equipped with an adhesive layer and are made with spatial separation of the biosignal pickup and electrical connection zones , between the ECG electrodes there is an additional biometric sensor for recording physiological health indicators, made either in the form of an acoustic sensor or a galvanic skin response sensor, in addition, on the lower side surface of the the housing has a multi-pin sealed connector designed either for connection to a computer, or to a charger adapter, or to additional remote sensors; the aforementioned photoplethysmographic biometric sensor is located at one end of the upper surface of the device in a shaped recess that repeats the shape of a fingertip, a group of outputs for LED indicators for controlling operating modes is located in the central part on the upper side surface of the housing at the point of its connection with the edge of the upper surface and has pictograms - in the form of a battery, indicating the degree of discharge of the built-in battery, which lights up in red when the battery is unacceptably discharged, in the form of a triangle with an exclamation point inside; lights up in blue when critical health conditions occur; in the shape of a heart, turning green, to indicate the state of attachment of ECG electrodes to the body, and additional remote sensors are made in the form of a third ECG electrode or a temperature sensor.

The claimed device has the following advantages compared to analogues and prototype:

1. The stability and reliability of registration and measurement in a wearable mobile device in the zone of its placement on the chest of such important physiological health parameters as a pulse wave signal and blood oxygen saturation SPO2 is increased. This is achieved in two ways.

Firstly, due to the proposed design of the upper surface of the body and the placement of an optical sensor in it, the photoplethysmography signal for reflection is taken in the chest area through the finger, in which, due to a larger number of capillaries, the peripheral blood flow and blood pulsation becomes approximately 50% larger: as a result, the the final information optical signal and, accordingly, the stability and reliability of registration of both the pulse wave and blood saturation.

Secondly, high artefactual venous waves, which can appear if the sensor is located significantly below the level of the heart, leave the signal of the photoplethysmogram taken on the chest. This also increases the reliability of the measurement, since artefacts from the pulsation of the veins go away.

The implementation of all photodiodes in the optical sensor in the same plane and the placement of the photodetector after the emitting photodiodes in the direction of the axis of the shaped recess provides the maximum value of the signal-to-noise ratio in the photoplethysmogram signal.

2. The cost of manufacturing the device is reduced by 20 - 30%, and the thickness of the body as a whole is reduced by 2 - 3 mm due to the exclusion from the design of the device of the polyamide display and control panel located in the figured lowering of the body. Due to the complexity of the technology, the production of a polyamide display and control panel is carried out in several countries (China and Russia, production is impossible only in Russia), which causes an increase in the cost of the final design and makes production dependent on the work of foreign enterprises. The proposed solution is aimed at import substitution and cost reduction. In addition, the LEDs for indicating modes and operating states become directly visible to the user, which was not possible in the prototype. This improves the usability.

3. It becomes possible to fix the device on the body using standard chest belts without compromising functional performance. In the prototype, this was prevented by the placement of optical and temperature biosensors on the lower surface of the housing in contact with the human body. In the proposed solution, the photoplethysmographic biometric sensor is located on the upper surface of the housing, and an additional temperature sensor is connected by a connecting cable to the multi-pin connector on the lower side surface.

4. It eliminates the need for constant temperature calibration of the temperature sensor when it is installed in different places of the human body. When fixing any temperature sensor in different parts of the chest, the measured temperature values in different places will be different and different from the accepted standard temperature grid, reduced to a base value of 36.6 ° C (in fact, they will vary from 33.5 ° C to 35.5 ° C depending on the selected installation site). Therefore, it is necessary to apply special methods and algorithms to bring the measured temperature values to the values of the standard temperature grid: Remote temperature sensor with its installation in the armpit area allows using the standard temperature grid without any calibration.

The essence of the invention is illustrated in the drawings, where:

In FIG. 1 shows a general view of the device with connected external ECG electrodes, charger adapter; remote temperature sensor, as well as the process of applying a finger to a device for measuring blood saturation SPO2 and pulse wave;

in fig. 3 - bottom view of the device (a), as well as possible types of biometric sensors - an acoustic sensor (b), a galvanic skin response sensor (c);

in fig. 4 - view of the device from the side of the multi-pin connector (a), as well as a view of the device from the side of the LED indicators (b);

in fig. 5 is a side view of the device.

The device contains a housing 1, on the upper side of which there is a power on/off button 2, a functional alarm button "Symptom" 3 and a photoplethysmographic biometric sensor 4 (Fig. 2) operating in reflection mode when the user's finger touches it. This allows you to measure blood oxygen saturation with clinical accuracy and remove the pulse wave.

A multi-contact connector 5 is hermetically integrated into the side surface of the housing 1 with the possibility of connecting an additional ECG electrode 6, or an additional temperature sensor 7, or a charger adapter 8, or a computer.

On the lower surface of the body 1, flush with it (Fig. 3a), there are push-button detachable connectors 9 and 10 for connecting flexible electrodes 11 and 12, located at a distance of 45 mm from each other.

An additional biometric sensor 13, as an embodiment, is located on the lower surface of the housing 1 between the button connectors 11 and 12. This sensor can be made as an acoustic sensor 14 (Fig. 3b) or a galvanic skin response sensor 15 (Fig. 3c).

On the upper side surface of the case, in its center, there is a group of LED indicators 16 with graphic pictograms (Fig. 4b) - in the form of a battery, indicating the degree of discharge of the built-in battery, which lights up red when the battery is unacceptably discharged, in the form of a triangle with an exclamation mark inside; lights up in blue when critical health conditions occur; in the shape of a heart, turning green, to indicate the quality of the state of attachment to the body of the ECG electrodes.

The device works as follows:

The device is fixed on the patient's chest using adhesive ECG electrodes 11 and 12, for example, in the area of the modified ECG lead II, or fixed on the chest belt using detachable contacts 9 and 10. Using the power on-off button 2 on the device, the remote health monitoring monitoring mode is activated. The ECG biopotentials created on the human body during the work of the heart are taken using electrodes 6, 11, 12 and fed to the biopotential amplifiers located on the board mounted in the device, from where they are digitized and sent for further processing to the digital signal processing unit. If necessary, the patient measures blood oxygen saturation, pulse wave and blood pressure by applying a fingertip to the photoplethysmographic sensor 4 (Fig. 2. b), the signals from which are also sent to the digital signal processing unit, or the temperature by connecting the temperature sensor 7 to the connector 5 and fixing the sensor 7 in the armpit of the patient. It also receives signals from the biometric sensors shown in Fig. 3. All these signals are pre-processed according to the algorithms corresponding to each type of biometric sensors, and then analyzed in the dangerous state analyzer located on the internal board. At the same time, health monitoring data is recorded on the built-in SD memory card and transmitted via Bluetooth radio to an external communicator (smartphone or tablet), from where it is then transferred to a cloud server for data storage and further processing. If a person is within dangerous boundary conditions, the analyzer warns about this by the blue glow of the LED indicator of alarm conditions and the vibrating alert, as well as by sending special alarm notifications to the mobile application (smartphone, tablet) without the participation of the patient. If the patient is able to independently assess the deterioration of his health or even the onset of a critical condition, he can also press the alarm function button 3. If the patient falls, the built-in accelerometer in the fall sensor mode will also notify the mobile application (smartphone, tablet) and then the cloud server about the fact of the fall and the place of the fall (according to the satellite navigator of the smartphone).

Using a photoplethysmographic sensor, data are generated on the level of blood oxygen saturation, which can serve as an indicator and a harbinger of a possible onset of a stroke (5 hours before the onset of a crisis). In addition, synergistic processing of ECG and pulsogram signals allows you to assess blood pressure at any time of the day without the use of an inflated cuff. Similarly, the signals of other biosensor sensors will allow us to assess the state of health from other autonomic regulatory systems.

When the device's built-in battery is charging, the charge indicator will warn you by glowing red. To charge the battery, a standard +5V power supply with a microUSB connector connected directly to connector 5 can be used. Data from the device’s memory for many days of operation can be rewritten, if necessary, to an external computer (for analysis, data transfer to the cloud, and other purposes) via the data cable, which is also connected to the multi-pin connector 5.

The proposed invention has achieved the technical result formulated in the objective of the invention and consisting of:

- in increasing the stability and reliability of registration and measurement in a wearable mobile device in the area of its placement on the chest synchronously with the ECG signal of the pulse wave signal and blood oxygen saturation SPO2. The implementation in the optical sensor of all photodiodes in the same plane and the placement of the photodetector after the emitting photodiodes in the direction of the axis of the shaped recess provides the maximum value of the signal-to-noise ratio in the photoplethysmogram signal;

- reducing the cost of manufacturing the device by 20 - 30%, as well as reducing the thickness of the case by 2 - 3 mm due to the exclusion from the design of the device of the polyamide display and control panel, located in the figured lowering of the case, simplifying the manufacturing technology and solving the problem of import substitution;

- placement of LEDs for indicating modes and operating states in direct visual accessibility to the user's eye, which was impossible in the prototype and which simplifies the operation of the device;

- fixing the device without violating its functionality using standard chest belts due to the fact that in the claimed solution the photoplethysmographic biometric sensor is located outside the lower surface of the case, and an additional temperature sensor is connected by a connecting cable to the multi-pin connector on the lower side surface;

- eliminating the need for constant calibration of the temperature of the temperature sensor when it is installed in different places of the human body due to the implementation of the temperature sensor remote with its installation in the armpit area, which allows you to use a standard temperature grid without any calibration.

To confirm the correctness of technical solutions, a working prototype of a wearable mobile device for remote monitoring of multiple physiological indicators of health status was made. Tests of the device have shown that it can measure SPO2 blood oxygen saturation on the human body in the range of 70 - 99% with an accuracy of ± 2%, and pulse characteristics in the range from 30 to 200 beats / min. The measured values completely coincided with similar parameters of standardized pulse oximeters. The temperature sensor, made on the basis of the TMP117 microcircuit, connected with a connecting cable to a multi-pin connector, showed the possibility of measuring temperature with an accuracy of 0.1°C when located in the armpit without the need for calibration. The placement of the LEDs for indicating modes and operating states on the upper side surface showed greater ease of use than when placed on a flexible polyamide display panel.

The proposed device, with wide functionality, is characterized by ease of operation and low cost, which makes it available for preventive use by the general population, including at home, which is very important.
