Description

The invention relates to medical equipment and is intended to create personal medical devices for remote monitoring of the patient's cardiac activity in an outpatient setting - cardiomonitors.

Electrocardiograph monitors are known that perform ECG recording on 12 standard leads using 10 electrodes. Such a monitor consists of a unit for amplification, processing and recording of a signal mounted on a person’s belt, and a patient cable, consisting of 10 wires going to standard ECG points. Such a device is installed on the patient’s body in a medical institution, and then, on an outpatient basis, cardiograms are recorded on 2 or 3 channels for a certain time, for example, a day (Holter monitoring). After that, the device is removed from the person and the data from the device’s memory are copied to the computer of a cardiologist. The doctor analyzes the dynamic change in the ECG, revealing abnormalities in the heart. The disadvantage of this device is the high level of interference induced by the patient’s long cable, and the lack of analysis of the recorded ECG for instant detection of dangerous cardiac abnormalities. In addition, he uses a wired data transmission, which makes it impossible to use it in the conditions of the patient's free motor activity.

The current state of radio engineering and computing facilities provides the ability to track the patient's vital signs with the help of portable cardiac monitors and transfer them to medical institutions.

Unlike traditional multifunctional clinical cardiomonitors (stationary, bedside, ambulances, etc.), in personal wearable cardiomonitors, restrictions on weight and size characteristics and power consumption are sharply highlighted.

Holter monitors are used to continuously record the patient's ECG for a period, such as a 24-hour period. However, the data recorded by the Holter monitor becomes known and can only be analyzed after the registration period has ended. Immediate ECG analysis is not possible because ECG data is only recorded and not reported immediately. In addition, when wearing a Holter monitor and because of its many wires and electrodes, many patients feel limited to participate in normal activities and often object to the discomfort and inconvenience of these monitors.

Known sensor devices for removing ECG (RF patent No. 2462984, IPC AB 5/00, publ. 10/10/2012, RF patent No. 2490808, IPC H04L 12/28, publ. 08/20/2013) containing an implantable sensor for taking parameters of the patient’s body . However, the use of the implant is limited because requires surgical intervention, which does not suit many users.

Applications (WO 2009112972, WO 2009112979, WO 2009112978, WO 2009112977, KONINKL PHILIPS ELECTRONICS NV, published September 17, 2009) describe an ECG monitoring system for outpatients, including a multi-electrode system that adheres to the patient’s chest. The processor constantly processes the received ECG signals, and the wireless transmitter transmits information about critical situations and the ECG signal to a cell phone and then to the monitoring center. A multi-electrode system increases the size and weight of the system, significantly speeds up the battery discharge time and reduces the time of continuous ECG monitoring.

The known design of the electrode device for a wearable ECG monitor (RF patent No. 2444988, IPC AB 5/0402, publ. 20.03.2012), containing a transceiver located on a belt with straps, tightly fitting the body. The belt with straps is made of elastic textile material. The transceiver includes sensors in the form of a system of cutaneous electrodes and a monitoring unit, electrically connected to each other. In this case, the system of cutaneous electrodes contains two arrays of pin electrodes mounted on a support in the form of a flexible dielectric substrate placed on the belt in the region of the front surface of the chest. The end free parts of the electrodes have a convex spherical surface and provide “dry” galvanic contact with the areas of the front surface of the chest in the conditions of natural patient movements. Each matrix consists of two groups, the pin electrodes in each of which are galvanically connected with each other, one of which - a larger area - is designed to remove the ECG signal, and the other - a smaller area - for connecting to common mode interference suppression means. The monitoring unit is located in a pocket on the belt.

The disadvantages of the device include the cumbersome design of the device, due to the use of a large number of pin electrodes in it, and status monitoring only by the user.

A known device for removing ECG at three special points (RF patent for utility model No. 94141, IPC AB 5/0402, publ. 05/20/2010), in which ECG is recorded at three special points on the human chest. The device includes at least three integrated active electrodes, an integrated reference electrode, an integrated “grounding” electrode, a three-channel biopotential amplifier, a control unit with an indicator that any of the channels of the biopotential amplifier go out of the given limits, an indicator of the ECG recording process, and non-volatile memory for storage transformation matrices, calculator for reconstruction of a standard ECG, an ECG analyzer for detecting health-hazardous conditions, an indicator of dangerous conditions, energy independent memory for storing monitoring data, an interface unit for communication with a computer. The hazard indicator is designed as a light and sound annunciator. The device is fixed on the patient’s chest in a certain place and monitoring for a certain time is turned on (for example, for a day - Holter monitoring). The ECG recording process is indicated by an indicator at the command of the control unit. The biopotentials created on the human body during the work of the heart are removed from three special points, the reference point and the "grounding" point using electrodes and fed to a three-channel biopotential amplifier. After amplification, the output signals of each channel are evaluated by the control unit from the point of view of going beyond the specified limits, the corresponding state is indicated by an indicator. From the control unit, the signals of all three channels are fed to a computer that reconstructs a standard ECG in 12 leads using an individual patient matrix stored in non-volatile memory. The matrix of the patient is pre-calculated on the computer of the cardiologist and recorded in the device through the interface unit. After reconstruction, the standard ECG signals are recorded in non-volatile memory, the volume of which is designed for the required monitoring time. In parallel with the recording, the analyzer uses a special algorithm to evaluate the ECG from the point of view of borderline hazardous conditions of the patient. If a person is in this state, the analyzer warns about this with an indicator. After monitoring, the data from the non-volatile memory at the command of the control unit is overwritten through the interface unit to the computer of a cardiologist for a detailed analysis.

A disadvantage of the known device is the presence of five electrodes with lead wires, which increases the dimensions and weight of the device, limits the patient's free motor activity, increases the influence of motion artifacts, significantly speeds up the battery discharge time and reduces the time of continuous ECG monitoring.

A well-known waterproof ECG monitor (RF patent No. 2512800, IPC АВВ 5/0432, G06F 19/00 publ. 04/10/2014), including a plastic double-leaf hermetically sealed case, which is removably connected to contacts fixed on a flexible base that is glued to the patient’s chest with adhesive material, a mobile phone handset and a charging dock, which is designed to recharge an ECG monitor and a mobile phone handset. Adhesive is applied to the bottom surface of the flexible base. On the lower part (the side facing the patient) of the adhesive contact are four hydrogel contact ECG electrodes, as well as a central contact ECG electrode, which is a control or RLD electrode. In the center of the flexible base, on the upper side, is a plastic clip with curved protrusions at the top and bottom, in which the ECG monitor is mounted and fixed. At the end of the day, before going to bed, the patient removes the used cardiac monitor from the adhesive contact and places it in the charging dock, from which before it pulls out a charged cardiac monitor and inserts it into the adhesive contact.

A disadvantage of the known ECG monitor is limited diagnostic capabilities, because due to the small distance between the ECG electrodes and the restrictions on their placement, it can only determine the heart rate (HR), and certain types of arrhythmias. Other disadvantages of the ECG monitor are the constructive complexity of connecting the contact electrodes of the cardiomonitor case to the flexible base and disconnecting from them, as well as the high power consumption due to the presence and need for power supply of the four electrodes, which increases the size and weight of the device, significantly accelerates the battery discharge time, reduces the time continuous monitoring of the ECG. Due to the high power consumption, the ECG monitor must be removed at the end of the day and recharged until the morning, and at night an additional ECG monitor should be connected to the ECG electrodes, i.e. the set should include two ECG monitors, which increases the cost of the known device. In addition, the presence of a single base for all ECG electrodes reduces the reliability of the snug fit of all electrodes during ECG registration due to the curved surface of the patient’s chest. It also limits the diagnostic possibilities due to work only in specific leads that do not allow revealing many significant problems of the cardiovascular system.

A mobile diagnostic device is known (RF patent for utility model No. 128469, IPC AB 5/00, publ. 05/27/2013) containing sensors of the patient’s biophysical parameters, including ECG sensors, a housing including an electronic circuit, microcontrollers, memory on an electronic medium, wireless data transmission module, autonomous power supply, module for cellular communications, a plate of elastic material with an adhesive surface treated with a conductive substance, on which the body of the main module of the device is attached, while c and a self-adhesive surface form a detachable connection.

A disadvantage of the known ECG monitor is the limited diagnostic capabilities, which are limited to determining only heart rate and identifying certain types of arrhythmias. In addition, the presence of various sensors of the patient’s biophysical parameters, including ECG monitoring sensors, increases the dimensions and weight of the device, and the need for their power supply significantly speeds up the battery discharge time and reduces the time of continuous ECG monitoring.

Known patch monitor for monitoring vital signs (application US US 2012029309, IPC AB 5/00, publ. 02.02.2012), containing at least two electrodes. In the body of the patch monitor is a plastic camera, which houses an electronic circuit, a wireless data transmission module, an autonomous power source.

A disadvantage of the known patch monitor is its limited diagnostic capabilities. Also, since a camera is attached on the same adhesive patch in addition to the ECG electrodes, the load on the patch increases and the reliability of the tight fit of all electrodes during ECG removal is reduced. It does not provide contacts for charging an autonomous power source. When the power source is discharged, a complete replacement of the entire body patch with all ECG electrodes and an electronic module is necessary, which is economically costly for the user.

All known wearable analog devices for ECG diagnosis have limited diagnostic capabilities, since they usually use a modified II chest ECG lead. This ECG lead correctly displays only the characteristics of the R-R intervals and rhythm variability and, as a result, is used in world medical practice to measure heart rate and detect arrhythmia. The detection of signs of ischemia in this assignment is very difficult due to the features of the passage and generation of electrical biosignals inside and on the surface of the human chest (New methods of electrocardiography, edited by S.V. Grachev, G.G. Ivanov, A.L. Syrkin, Moscow : Technosphere, 2007.). To predict the possibility of myocardial infarction, stroke, and other serious diseases, early detection of signs of ischemia is extremely important. Known analog devices do not provide such an opportunity.

Another common drawback of the known analogue devices is the short duration of operation from a single battery charging cycle (no more than a day), which complicates the operation of the devices and does not allow for the long-term monitoring necessary, for example, to identify episodic types of arrhythmias.

The objective of the invention is the creation of a native diagnostic patch device for individual self-analysis of ECG, providing long-term remote monitoring of cardiac parameters in real time, with broad diagnostic capabilities and the function of operational notification of the onset of a critical condition of a person, with maximum simplicity and ease of use, as well as minimum power consumption.

When solving this problem, a technical result is achieved, consisting in the possibility of:

- carry out long-term remote monitoring of cardiac parameters in real time for several days from one battery charging cycle;

- examine the patient for ischemia with the analysis of the ST-segment;

- examine the patient for arrhythmia, including its episodic types, which is ensured by the duration of monitoring;

- conduct a detailed analysis of arrhythmias with the identification of the place of their occurrence (supraventricular, ventricular, etc.), detect AV blockages;

- identify atrial fibrillation, distinguishing it from multiple extrasystole;

- to place the electrodes in the places of optimal detection of specific pathologies for the most informative analysis.

The technical result described above is achieved due to the patient’s long-term fixation of the under-body diagnostic device and other design features, in particular the presence of a sheath made of flexible biocompatible material, for example, medical rubber made with ears on the sides into which button electrodes are mounted, as well as the possibility of connecting an additional wired electrode. The use of a biocompatible material on the patient’s body minimizes allergic reactions of the body, reduces perspiration, protects the contacts located in the shell from self-discharge, all together reducing the ingress of moisture to the contacts and the possibility of shunting the battery, which reduces its discharge. This allows you to remotely diagnose the patient in the long-term mode, and this, in turn, increases the accuracy of detecting arrhythmias and ischemia. Connecting an additional wire electrode allows you to place it in the places of optimal detection of specific pathologies for the most informative analysis.

The solution of this technical problem is achieved by the fact that the under-body diagnostic device for remote continuous monitoring of the ECG includes a housing placed in a flexible shell, ECG electrodes equipped with an adhesive layer, and a charging dock. Inside the case there is a rechargeable battery, a biopotentials amplifier, an electronic ECG signal processing unit, an accelerometer, a memory for storing the accumulated ECG information, a wireless transceiver, magnetically conductive plates are mounted in the bottom cover of the case on its inside, and flat electrical contacts are mounted on the outside of the case cover. connected by an internal spring-loaded part to the electronic ECG signal processing unit, while the film I have a keyboard electrically connected to the ECG signal processing unit by means of a flexible cable, and the keyboard has a power on / off button, a Symptom button with a tactile press to initiate emergency data transfer to a mobile device, such as a smartphone, and LED indicators for displaying various operation parameters devices - the functioning of the Bluetooth radio channel, the presence of contact of the ECG electrodes with the patient’s body and heart rate, as well as the battery charge level; the flexible shell is made with two opposite elongated sections, in which button connectors are mounted, with the possibility of connecting ECG electrodes, and electrically conductive elements connecting these connectors to the inputs of the biopotential amplifier, and a socket connector is made in the side of the case with the possibility of wiring a third additional ECG- an electrode with an adhesive layer, fixed under the patient’s chest in the area of the modified CM5 ECG lead and intended for examination of the patient for ischemia. In addition, the device contains a charging dock, which is designed to recharge the battery, and also provides the ability to read data from an SD card, pin-spring contacts are installed on the upper surface of the charging dock, and flat magnets are mounted on the inside and under them a plate of magnetically conductive metal is located for shunting the magnetic field outside the charging station and its amplification in the direction of the charged body diagnostic device. The device memory is made in the form of an SD card for intermediate data buffering during data transmission over the air, as well as for long-term continuous archiving of ECG data. Thus, the presence of the mentioned elements, their mutual arrangement and relationship ensure the achieved technical result of the device as a whole.

The advantage of the proposed device is the use of only two main electrodes, which significantly reduces power consumption, battery discharge time and increases the time of continuous ECG monitoring.

The presence of an additional connector in the housing for connecting an additional wire electrode with an adhesive pad allows you to fix this electrode under the chest in the area of the modified CM5 ECG lead and further examine the patient for ischemia. At the same time, it is possible to electronically control the inclusion of a wired electrode using the "Symptom" button on the film keyboard. The use of only one additional electrode for diagnosing ischemia does not significantly increase the power consumption of the wearable device.

The use of adhesive electrodes for diagnosing arrhythmias and ischemia due to the large area of contact of their contact surfaces with the patient’s body contributes to the improved transmission of signals (currents), which significantly reduces power consumption, battery discharge time and increases the time of continuous ECG monitoring.

The use of push-button contacts simplifies the attachment and detachment of the body of the on-body diagnostic device to ECG electrodes in comparison with the known device.

The presence of an adhesive pad for each electrode increases the reliability of the tight fit of each electrode to the patient's body.

A shell of flexible biocompatible material into which the housing is inserted can take the form of a body, which also improves the contact of the electrodes with the patient’s body.

The presence of magnetic contacts in the charging dock between the body of the under-body diagnostic device improves the quality and reliability of the electrical contacts between them during the charging process, which ensures battery charge continuity, shortens charging times and extends the useful life of the diagnostic device.

Installing a film keyboard on the upper surface of the case, on which the on / off buttons, the Symptom button, and LED indicators to display various parameters of the diagnostic device are made, simplifies device management and tracking of its operation parameters.

Using an SD card as the device’s memory improves the quality of ECG transmission in conditions of interference due to intermediate data buffering, it also provides long-term monitoring with data archiving and allows you to store a long-term archive of the patient’s ECG status with the option of choosing the right data for the ECG analysis from the archive.

in FIG. 3 - the location of the connectors for connecting ECG electrodes, magnetic conductive plates and electrical in the body of the wearable device, as well as magnets and electrical contacts in the charging dock;

in FIG. 4 - charging dock with a diagnostic device in the process of charging it.

The wearable device of FIG. 2 contains a housing 1 made of plastic into which an accumulator battery 2, a biopotential amplifier 3, an electronic ECG signal processing unit 4, an accelerometer 5, a memory for storing the accumulated ECG information (SD card) 6, and a wireless transceiver are integrated (integrated); Bluetooth radio module) 7, and also contains two adhesive ECG button electrodes 8, 9 and an additional electrode 10 with a flexible conductor for connecting to the electronic unit in case of ischemia patient examination, in addition, the device contains a charging dock 11 to charge the battery 2. The housing 1 is fused into a shell 12 made of flexible biocompatible material, for example medical rubber, made with elongated sections on the sides, for example in the form of lugs 13. Button sockets 14 are fused into the ears 13 for connecting to the button part of the ECG electrodes 8, 9. In addition, electrically conductive elements 15 are mounted in the ears 13 for connecting the ECG electrodes 8, 9 with the inputs of the biopotential amplifier 3. In the niche of the shell on the upper part of the housing 1, a film keyboard 16 is fixedly connected to the electric unit 4 ronnoy processing ECG signals by means of a flexible loop, for example of polyamide. The on-off button and LED indicators are made in the film keyboard 16: blue - displays the Bluetooth operating mode, green - the presence of ECG electrodes in contact with the patient's body and heart rate, red - the battery charge level. In the center of the film keyboard 16 is a button "Symptom" 17 to initiate emergency data transfer to a mobile communication device 18, such as a smartphone, in case of emergency. A connector 19 is made in the side of the housing 1 for wiring an additional third electrode 10. Two magnetic conductive plates 20 are mounted on the inner side of the back cover of the housing 1. And flat electrical contacts 21 are mounted on the outside of the housing cover 1, which pass through the cover and their spring-loaded ends contact with the ECG signal processing unit 4 and through it are connected with the battery 2. Contacts 21 are designed to charge the battery 2, as well as the accumulation x data from the memory (SD card) 6 and connected to the contacts 22 in the charging dock 11, during the charging process of the device. The charging dock 11 is made in the form of a stand having a niche repeating the shape of the body 1 of the wearable device, in which a connector 23 is made (Fig. 4) for wiring the charging dock 11 to the power supply. Two flat magnets 24 are mounted under the upper surface of the docking station 11 in the projection area of the magnetically conductive plates 20 of the housing 1, for example, of a neodymium alloy, as well as a magnetically conductive metal plate for shunting the magnetic field outside the charging station and amplifying it in the direction of the charged body diagnostic device. In the process of charging the battery 2 of the wearable device, as well as removing the data archive from the memory (SD card) 6, the flat ends of the contacts 21 of the housing 1, due to magnetic contact, are tightly connected to the spring-loaded contacts 22 of the charging dock 11.

ECG registration and monitoring of cardiac activity is as follows:

The wearable device is fixed on the patient’s chest in a specific place, for example, in the area of the modified II ECG lead, and monitoring for a certain time is turned on using the power on / off button on the film keyboard 16. Using the mobile application 25, a continuous or cyclic mode of operation is set at selectable intervals. In the mode of analysis of arrhythmia, the biopotentials created on the human body during the work of the heart are removed using electrodes 8, 9, and fed to the first and second channels of the biopotential amplifier 3. After amplification, the output signals of each channel are converted from analog to digital using analog a digital converter (ADC) located in the ECG electronic signal processing unit 4. The digitized signals are further processed in the signal processing unit, then analyzed in the hazardous state analyzer from the point of view of overcoming them set limits. If a person is within the border of dangerous states, the analyzer warns about this using the mobile application 25 and the blinking of all indicators on the film keyboard 16. In addition, the dangerous state analyzer has the ability to initiate the forced registration of critical conditions and emergency data transfer to the mobile application 25. Data monitoring are recorded in the memory of the SD card 6, and also through a wireless transceiver, for example a Bluetooth radio module, are transferred to the mobile application 25 of the mobile device Communication equipment 18, for example, a smartphone or a computer, and then through a GPRS module to the Internet for storage and further intelligent processing of monitoring data.

The use of two electrodes 8, 9 can warn the user about arrhythmic abnormalities of the heart rhythm. In addition, the accelerometer 5 detects the movement of the wearable device connected to the patient, and, therefore, estimates the patient's motor activity, and is then used to interpret the possible conditions of the patient.

For effective diagnosis of signs of ischemia, it is necessary to connect a flexible conductor plug with a third electrode 10 to the connector 19 of the housing 1 and fixing the electrode 10 on the patient’s body under the chest in the area of the modified CM5 ECG lead. Data from the three electrodes 8, 9, 10 are likewise received, amplified, processed, analyzed, and in the event of a deviation from the normal state, the user is warned about this using the mobile application 25 and indicators on the film keyboard 16.

When charging of the battery 2 ends, on the film keyboard 16, the charge indicator is solid red. In this case, the patient disconnects the electrodes 8, 9, 10 from the connectors 14, 19 and places the device in the charging dock 11.

In the present invention, a positive effect is achieved, consisting of:

- the possibility of additional examination of the patient, in addition to arrhythmia, also for ischemia, which significantly expands the functionality and practical applicability of the device, while for the diagnosis of ischemia only one additional third electrode is required, fixed in a special place on the patient’s body, for example, in a modified SM- 5 ECG leads, where the ST segment has a maximum amplitude;

- the ability to identify not only the fact of artimia, but also the place of its occurrence (supraventricular, ventricular, etc.), as well as various other pathologies due to the ability to choose the optimal location of the body module;

- to increase the duration of the device from one charging cycle from one day to several days due to the reduction of energy consumption provided by the use of a minimum number of ECG electrodes, minimization of leakage currents through the use of a moisture barrier and the use of optimal circuit-saving energy-saving solutions in the design of an electronic ECG signal processing unit - this allows you to identify episodic types of arrhythmias;

- the possibility of emergency data transfer to a mobile device both at the initiative of the patient through the use of the Symptom button, and automatically according to the results of an internal analysis of the ECG signal in the analyzer of dangerous conditions;

- to improve the quality and reliability of data transmitted to a mobile device via a wireless channel in a difficult signal-to-noise environment due to intermediate ring buffering of data in memory (SD-card) and the possibility of re-sending a data packet instead of the damaged one;

- the ease of self-installation of the wearable device by the patient himself with a visual check of the appearance and amplitude of the signal on the screen of the mobile device, which allows you to use the device at home;

- the possibility of long-term archiving of the data stored in the SD-card memory for the subsequent analysis by the doctor of any ECG fragments of medical interest with reference to these symptoms accompanying them;

- to ensure high-quality and reliable contact between the wearable device and the docking station during charging or data collection due to the magnetic clamping of the surface of the wearable device to the surface of the charging docking station, which ensures battery charge continuity, shortens charging times and extends the life of the diagnostic device.

The proposed device is effective in the rapid detection of cardiac abnormalities, characterized by ease of use and relatively low cost. More than 10 million Russians suffer from heart disease, especially atrial fibrillation and coronary heart disease. Heart failure kills half of the patients within five years of being diagnosed. Therefore, the wearable diagnostic device for cardiac monitoring at home is very important.
