Description

The invention relates to medical equipment and is intended for measuring blood pressure and other indicators of the cardiovascular system in the remote control mode and monitoring.

Blood pressure control is extremely important for the prevention and treatment of hypertension, the prevalence of which in different countries is from one third to half of all examined. Moreover, hypertension is not only one of the most common pathologies of our time, but also the most important risk factor for cardiovascular complications, especially cerebral stroke. Modern research data has shown that active involvement of patients in regular monitoring of blood pressure leads to a 48% reduction in mortality from cerebral stroke, and subsequent adequate control of blood pressure leads to a 28% reduction in the risk of re-stroke. However, at present, less than 10% and slightly more than 10% of women have registered appropriate controls. Particularly problematic is the monitoring of blood pressure in patients, which requires mandatory visits to the doctor to install an appropriate monitor and repeated calls to decipher the monitor and obtain appropriate recommendations from the attending physician. Due to this, the solution of the problems of adequate control and monitoring of blood pressure, especially at home, can effectively deal with the complications of high blood pressure and reduce mortality from cardiovascular diseases.

A device for monitoring blood pressure containing a shoulder cuff, a compressor for generating pressure in the shoulder cuff, a pressure sensor in the cuff, a unit for calculating blood pressure indicators, a memory unit that allows automatic measurement of blood pressure at predetermined time intervals and then entering them into a PC ( Ambulatory blood pressure monitoring systems for blood pressure and pulse TM-2420 / 2020. Modern electronic means for measuring, monitoring and controlling blood pressure A&D Compan y, Limited Tokyo, Japan).

The disadvantage of this device is the impossibility of its independent use by the patient at home due to the fact that it is designed to be serviced by special medical staff in a medical facility.

A device for automatic control and monitoring of blood pressure containing a shoulder cuff, a compressor for generating pressure in the shoulder cuff, a cuff pressure sensor, a unit for calculating blood pressure and heart rate, an indicator for displaying blood pressure and heart rate (Automatic blood pressure meter UA-767 PC. Modern electronic blood pressure measuring, monitoring and control equipment. A&D Company, Limited Tokyo, Japan). This device is intended for domestic use and allows automatic measurement of blood pressure when turned on manually and, if necessary, enter the measurement results into a personal computer. The advantage of this device is its relatively low cost, due to mass production, high accuracy of blood pressure measurement, reliability, ease of use.

The disadvantage of this device is the inconvenience of its use for monitoring blood pressure associated with additional operations to enter data into a personal computer. In addition, in order to analyze the results of monitoring, the patient must appear for consultations with the attending physician, or keep his own observation diary.

The closest in technical essence and the achieved result to the claimed is a device for monitoring and monitoring of blood pressure (RF patent No. 2299008), created on the basis of manufactured blood pressure meters, containing a blood pressure meter, a microcontroller unit, a digital memory unit, a clock chip, a recording unit and sound reproduction. This device allows you to measure blood pressure and heart rate at programmed points in time, to accumulate and analyze the measurement results over long time intervals with the issuance of information to the patient in gradations "norm" - "excess of norm", transferring the analysis results via telephone communication channels or to a personal computer .

The method of measuring blood pressure, implemented using the device according to the patent of the Russian Federation No. 2299008, is based on setting the parameters of the measurement mode and controlling the blood pressure meter, measuring and analyzing the blood pressure data of the patient at certain intervals, reproducing data on a graphical or digital indicator and, if necessary transfer of accumulated information to diagnostic centers via telephone communication channels.

The disadvantages of the method and device that implements it is the need to obtain the recommendations of the attending physician for preliminary programming of the parameters according to which the blood pressure monitor will function, as well as the incompleteness of the analysis of the measurements made, accumulated in the device itself. In addition, the accumulated information is transmitted to diagnostic centers via separate telephone communication channels, which requires additional equipment for measuring blood pressure with appropriate external equipment and a number of additional data sending operations.

The lack of automatic transmission of data obtained as a result of monitoring the patient’s blood pressure to diagnostic centers does not allow medical specialists to obtain a reliable picture of the patient’s pressure indicators in the optimal time frame, which, in turn, does not contribute to the development of timely optimal treatment recommendations.

The main task solved by the claimed method and device is the creation of a method and device that allows you to control and monitor blood pressure at home by automatically transferring data to the medical site of active observation, in which any user of the device can have an individual page that reflects the diary of observations with medical data, which will improve the reliability of diagnostics and ensure timely issuance of recommendations to users by medical specialists and.

The technical result is an increase in the convenience of monitoring blood pressure and the quality of diagnosis based on promptly obtained measurement data, as well as for a period of long-term observation. At the same time, the functional capabilities of the methods and devices for monitoring blood pressure are expanded, which is achieved by providing the device for measuring blood pressure with an additional function - receiving and transmitting data during monitoring directly from the device.

The unit 7 for displaying the measurement results and operating modes of the apparatus is made in the form of a display 10 on which a series of indicators of measurement results, operating modes, and data transmission can be installed.

The inventive device has a rectangular shape (figure 3). The display 10 is located at the top of the front panel of the apparatus.

The inventive device and method for remote control and monitoring of blood pressure works as follows.

The user acquires a device for measuring blood pressure with a cellular module installed in it (in the preferred embodiment) and installs a SIM card in the slot of the cellular module 6. Now all blood pressure and heart rate measurements are from time to time (by default, for example, after each 15- th measurement) are adapted for automatic sending to the server of a medical website. All measurement values are correlated with the mobile number of the SIM card and digital identifier - a unique device code specified in the user manual and on the rear panel of the device. Each device has a unique 9-digit digital identifier. Each incoming CMC message must begin with this number. If the code does not match, then the incoming message is ignored.

Later, the user can go to the site, enter the mobile number of the SIM card, the digital identifier of the device and gain access to all stored data.

The user can also register on the site in manual mode. In this case, he enters his personal data and forms his personal page, to which subsequently the measurements made by the device according to the claimed invention are attached. To do this, you must also enter the mobile number of the SIM card and the unique code of the device. All measured data and the results of subsequent measurements will be on the individual user page.

The device according to the claimed invention can be used for daily or 12-hour monitoring, as well as for single measurements at the request of the patient with remote transmission of data to a medical website. Before taking measurements in this mode, the user must make sure, in accordance with the readings of one of the communication indicators, that the SIM card is installed, and based on the readings of the time and date indicators, that the time is set correctly. When the device is turned on by the switch 11 for measuring pressure, the unit 2 for creating and depressurizing pumps air into the cuff 1 connected to the input of the unit 2, and also bleeds the air from the cuff. Block 2 transmits the current value of the pressure in the cuff to the input of block 3 for determining blood pressure, which can also determine the heart rate or other indicators of the state of the user's cardiovascular system.

Block 3 determining blood pressure through an appropriate output sends control signals to block 2 for creating and depressurizing and converts the corresponding pressure signal in the cuff 1 coming from the output of block 2 to the input of block 3. In accordance with these signals, the value of systolic and diastolic blood pressure , as well as heart rate. The measured values from the output of blood pressure determination unit 3 are sent to a processor 5 with non-volatile memory and to a display unit 7, which displays the measurement results and operating modes, and data transmission.

In one of the implementations of the claimed invention, the display unit can be made in the form of a unit for reproducing sound signals designed to alert about the measurement results, operating modes and data transmission. The indicated implementation option may facilitate the use of the claimed device by older people, since in this case the measurement result is duplicated by notifying the user, in addition, the sound signals can be sent when switching the monitoring modes, etc.

The processor 5 is the central node that provides support for operating modes, the monitoring process, the storage of measurement results and their timely sending to the server. He coordinates the operation of the entire device and controls the operation of the unit 3 for measuring and determining blood pressure by supplying a signal for measuring pressure. The processor 5 initializes the transceiver unit 6, for example, a GSM cellular module, and checks for the presence or absence of an installed SIM card.

If a SIM card is installed, then processor 5 reads its IMSI. Next, the processor checks in its memory whether a SIM card with such IMSI was used in the device or not. If a SIM card has not been used, then a new entry is made in the well-known IMSI buffer, otherwise the already known IMSI is used. The processor also reads the value of the communication level, for example, at the request of the GSM module.

The processor checks the setting of the current time and date and determines the operation mode of the device (if the time is set, the date and the SIM card are installed, the device will be launched in personal mode).

At each moment of time, the device for measuring pressure and heart rate can be in various internal operating modes, such as: standby mode of a user command, pressure measurement mode, sending mode of CMC messages, manual time setting mode, etc. Each mode is characterized by a set of current parameters, and the processor accordingly sets the necessary indicators and properly responds to pressing the switches of the control unit 8, etc.

The processor 5 also checks the cellular module for incoming CMC messages. If there is such a CMC message, the code is verified at the beginning of the CMC message with an individual number and, if there is a match, the operation programmed in the CMC message is performed. So, for example, several types of control CMC messages are possible:

- Setting a custom monitoring profile

- Setting the current time

- Reset all settings to factory settings

- Forced sending CMC messages to the server.

The processor 5 receives the signals coming from the switches 11-15 of the control unit 8, and depending on the type of signals gives commands to measure pressure, switch to monitoring mode, exit monitoring mode, forced synchronization with the server, etc.

In the pressure measurement mode, the processor 5 does not respond to the user pressing the switches of the control unit 8, but instructs the blood pressure determination unit 3 to measure the pressure and heart rate. At each clock cycle, the processor displays information for the user on display 10. After a full cycle of pressure measurement (and this process takes a lot of clock cycles), if the pressure could not be determined, processor 5 goes into error display mode. In personalized mode, the processor saves the next measurement in memory (with the date and time of the measurement), checks the number of unsynchronized measurements with the server. If there are more than 15 unsynchronized messages, for example, the device goes into synchronization mode of unsynchronized measurements with the server.

In the monitoring mode, the processor 5 reconciles each measurement step with the measurement schedule programmed in the current monitoring profile. Measurements can be tied to the beginning of the monitoring mode, for example, measurements 2, 4, 6 hours after the start, or to the time of day, for example, measurements at 11:00, 14:00 and 17:00.

In the mode of synchronization of measurements with the server, the device sends the measurement results (with the date and time of measurements) using a specially generated CMC message to the mobile number programmed in the firmware of processor 5. The display 10 displays the send signal of the CMC message using a special indicator or, for example, pseudo-graphics.

The measurement result from one of the outputs of the processor 5 is supplied to the display unit 7, and also, if necessary, is stored in the non-volatile memory of the processor.

The transceiver unit 6, made in the preferred embodiment in the form of a cellular module, is designed to send a CMC message to the identification number of the CMC center of the medical site indicated in the processor firmware 5, as well as receive incoming CMC messages and send them to the processor 5 for processing corresponding output.

The input of the processor 5 receives control signals that are initiated by the user using the switches of the control unit 8. The device can be programmed using specially composed CMC messages, both from the server of the medical Internet site, and using the appropriate program used for the mobile phone.

The user can make measurements using the inventive device in a single control mode with one or more measurements. If the user measures the pressure using the first button 12, then the measurement result (three digits - systolic and diastolic blood pressure, as well as heart rate) with the date and time is stored in the device's memory. The memory allows storing, for example, at least 1000 measurements. In this case, the data of the measurement results can also be transmitted to the medical website.

For more objective observation, the user can use the device in the daily monitoring mode, which is carried out at the request of the user or as directed by a doctor. In this case, the device is fixed on the user's belt and is turned on only at the programmed moments of measurement or in the manual mode by the user. The daily monitoring mode is activated using the second button 13. In the device, for example, two hard-coded monitoring modes and three user modes that can be programmed by the user on his own or by his attending physician can be set. In this case, special software is used that allows for day or night 12-hour monitoring, which is displayed on display 10 using the appropriate indicators.

In monitoring mode, the user can perform an additional measurement of blood pressure using the first button 12, the results of which will also be saved with the corresponding measurement time in the device’s memory. The motive for an additional measurement can be the user's internal subjective sensations (for example, increased heart rate, poor health, etc.). You can exit the daily monitoring mode until it is naturally completed, for example, by long pressing, for more than 3 seconds, the second button 13. In this case, the daily monitoring indicator is turned off, but all measurements taken are stored in the device's memory.

In the process of measuring blood pressure, the device periodically sends the measurement results to the server. For example, at least 15 measurements can be placed in one standard CMC message, which at a low cost of these messages as a whole will be a small amount. When a certain number of measurements is accumulated, or by default, for example, after 15 measurements, the results are automatically sent to the number stored in the device’s memory with the required number of individual SMS messages. If communication is not available at this moment, the device transmits this measurement package during the period of each next measurement, since the number of the CMC module of the medical site is programmed in the device. If it is necessary to obtain information by the user (by pressing the third button 14), information on the number of unsynchronized messages with the server appears on the display. By pressing the button for a longer time, the user can force the sending of CMC messages to the unsynchronized measurement server. If there are no such measurements, then sending CMC messages will not occur.

The device, for example, after every 10th measurement (in this case, the value 10 can be programmed), can send a request for the balance on the SIM card account. If the balance is less than the specified threshold value, which can also be programmed, one of the indicators fixes the need to replenish the balance. By default, balance checking is disabled. Checking the balance occurs each time the device is turned on, until the balance is replenished.

Figure 4 schematically shows the interaction of the device according to the claimed invention and a medical website, which illustrates the implementation of the method.

The server runs all the software that coordinates the work of the site, saving the results from the server, etc.

The database contains all medical information, user registration data, news text, etc.

As a site, a web interface for accessing the site via the Internet, a CMC service, which allows the server to send CMC messages and receive CMC messages to the specified number, is schematically presented.

The Server, Database and Site can be made in the form of one or more computers interconnected. Typically, these computers are located in the data center of one of the providers. CMC service - usually provided by a third-party organization that allocates a special incoming number and provides the server with programmatic access to their CMC gate. Now all CMC messages sent to a special number will be sent first to the CMC gate, and then redirected to the medical server that will process them. Similarly, from this server you can send any CMC message to any mobile number. If the CMC message is intended for programming the inventive device, then it has a specific form, which can decrypt the inventive device.

The inventive method and device allows the patient to maintain their health passport and communicate with their attending physicians via the Internet.

A health passport can consist of information about diagnoses, doctor visits, prescribed drugs and courses of treatment, and is filled in personally by the patient or his or her attending physician. Also, on the personal page of the patient, blood pressure measurements are recorded by the claimed device in automatic mode.

Patients can keep a health passport, and medical specialists can communicate with them, prescribe medications or recommendations. Doctors can also assign special daily monitoring profiles to their users who have devices for measuring blood pressure according to the claimed invention. The method of remote control and monitoring of blood pressure and a device for its implementation allow optimal analysis of the dynamics of changes in blood pressure during a long observation period, which significantly increases the effectiveness of the treatment of arterial hypertension. Using the proposed method and device can also improve the prevention of diseases of hypertension and its complications and improve the diagnosis of the patient's cardiovascular system by timely monitoring of deviations of blood pressure from normal. The claimed invention improves the convenience of monitoring blood pressure and the quality of diagnostics both on the basis of operatively obtained measurement data and the results obtained over a period of long-term observation. At the same time, the functional capabilities of the methods and devices for monitoring blood pressure are expanded, which is achieved by providing the device for measuring blood pressure with an additional function - receiving and transmitting data during monitoring directly from the device.
