Description

The invention relates to the field of medicine, namely to the field of measuring vital indications of a person's condition for diagnostic purposes, as well as visualization and analysis of the obtained measurements and assessment of the state of human health.

Prior Art

A patent of the Russian Federation for the invention No. 2729430 "HARDWARE AND SOFTWARE COMPLEX FOR MONITORING LIFE SIGNS" is known. The complex is a T-shirt fixed on the chest with a strong component in the solar plexus area and straps on the shoulders and on the sensor attachment line under the chest. The shirt is made of elastic fabric material with a flexible polymer wiring system for distributing power from the central data aggregator. The device includes a wearable biochemical sensor for lactate and glucose content, a wearable semiconductor sensor for the temperature and humidity of the skin, a wearable electrocardiograph for 4-6 leads, a multispectral sensor for measuring pulse oximetry parameters, a sensor for measuring respiratory rate and volume based on tensometry data, and a blood pressure measurement sensor , a system of sensors for measuring motor activity. The wearable device transmits the received data to the stationary part via a wireless protocol (WiFi/Bluetooth/NFC or other)

The main disadvantages of this device are that it is quite bulky (including due to a wearable blood pressure cuff), requires long-term wear (since it is a wearable wearable device) and individual selection of the size of the complex for each patient.

Known RF patent for invention No. 2735925 "MOBILE DEVICE FOR CONTINUOUS REMOTE HEALTH MONITORING", The device contains a housing, three external flexible ECG electrodes, equipped with a layer adhesive to the body. The electrodes are made of an oblong shape with spatial spacing of the biosignal pickup and electrical connection zones. Two electrodes are connected directly to push-button connectors located at the remote ends of the lower surface of the housing, and the third is connected by a conductor to the female connector on the side surface of the housing. This device suggests the possibility of using additional biosensors in the same construct and obtaining additional data on blood oxygen saturation, blood pressure, stress level and stroke blood ejection, assessing extraneous heart and lung sounds, etc., which is currently not implemented.

The disadvantages of this device is the need for prolonged contact with human skin, limited opportunities for obtaining highly reliable high-quality information that can be used for medical purposes.

Known US patent 7896811 B2, according to which the device is made in the form of a bracelet that records ECG data, photoplethysmography and differential photoplethysmography. At the same time, ECG data registration is achieved due to the fact that one electrode is located on the inside of the bracelet, which is located on one hand of a person, and the other electrode is located on the outside of the bracelet and contacts the skin of the other hand of a person. In this way, the measurement of the potential difference from two hands and the calculation of one ECG lead is achieved.

The main disadvantage of this device is limited diagnostic capabilities, since the ECG is recorded exclusively in one lead.

Known RF patent No. 2690112 "PORTABLE DEVICE FOR RECORDING ELECTROCARDIOGRAM" USB device FROM No. 2690112. Analogue biopotentials from cardioelectrodes attached to certain points of the human body enter the device and then are transferred by wire to the port of an external device such as a computer, smartphone or tablet. The analog circuits of the device are powered from the unipolar USB port of the external device. Information is displayed on an external device.

The disadvantages of this device are wired communication, as well as the ability to register only one parameter - electrocardiography, which excludes the possibility of a comprehensive assessment of the state of human health.

Known application for the issuance of US patent 2014/0228665 Al, which describes a device that allows you to register an electrocardiogram in 12 leads. The data is transmitted, visualized and analyzed on a stationary device. A distinctive feature of the device is the presence of two electrodes, which are sequentially located on the human body in such a way that the ECG signal is recorded in several leads.

The disadvantage of this device is that the device does not allow you to record ECG data at once, therefore, it requires a lot of time. In addition, the device has narrow diagnostic capabilities, as it only allows recording ECG data.

Diseases of the cardiovascular system occupy a leading position among the causes of death in the population. Sudden cardiac death accounts for 90% or more of all sudden deaths.

A number of diseases highly associated with sudden cardiac death, such as primary electrical heart disease, may have minimal manifestations and require data to be recorded at the time of the attack. At the same time, timely diagnosis of changes in the cardiovascular and respiratory systems can be difficult due to many reasons. These include: remoteness from the medical facility at the time of the attack, the short duration of the attack, the inaccessibility of medical care, the need for frequent outpatient monitoring of the condition, and others.

One of the significant difficulties that doctors encounter when conducting a diagnostic search is the registration of short-term bouts of changes in a person’s well-being (for example, bouts of paroxysmal atrial tachycardia). In such cases, the diagnosis and the choice of treatment tactics entirely depend on the data obtained at the time of the change in the person's well-being. At the same time, recording data at the time of an attack can be significantly difficult due to a number of reasons, such as the short duration of an attack, remoteness from medical institutions, the duration of the assessment of the patient's condition using several diagnostic links, and more. The use of a portable device that can record data during seizures helps to solve this problem.

Medical and pre-medical diagnostics of the state of human health is based on a comprehensive assessment of several vital indicators. Currently, ECG is one of the basic methods for diagnosing the state of the cardiovascular system. Using ECG data, you can get information about such vital signs as heart rate, heart rhythm, the presence of ischemic changes, etc. However, a correct assessment of ECG data is not always possible due to the lack of information about the state of other organs and systems. Thus, a change in heart rate may be due to a change in body temperature and/or blood saturation. For a competent assessment of ECG data, it is necessary to take into account other indicators of the vital activity of the human body, such as body temperature, blood saturation, and cardiac output. At the same time, the assessment of several indicators, as a rule, requires the patient to contact a medical institution, which can be difficult for a number of reasons. The use of a portable device capable of recording data from several vital signs is an important step in overcoming these difficulties.

In the presence of chronic diseases of the cardiovascular system, the isolated fact of the presence of deviations from the norm on the part of the ECG data does not give an idea about the course of the disease, as a result of which it makes it difficult or impossible to correctly assess the ECG data. Changing dynamic indicators using a portable device will have a greater diagnostic and prognostic value.

At present, the relevance of monitoring the state of human health, taking into account the minimization of time costs, is constantly growing. Timely diagnosis of pathological conditions with a reduction in the time from data registration to diagnosis contributes to the appointment of correct treatment, which ultimately leads to a decrease in morbidity and mortality from socially significant diseases.

At the moment, the number of portable devices being developed by scientists from different countries for the purpose of a comprehensive assessment of the state of human health is constantly growing. However, at present, most multifunctional devices are large or, on the contrary, being highly compact, have little functionality and are able to register only one or two vital signs of a person. The use of most devices currently on the market is complicated due to the presence of a large number of wired connections and/or bulky sizes. Multifunctional devices that include multiple sensors typically involve extended wear on the human body, making such devices inconvenient for on-demand use. On the contrary, small compact devices, which could be convenient for data recording both by a medical specialist in clinical practice and by a patient in an outpatient setting, do not have high functionality and sufficient accuracy for diagnosing a wide range of pathological conditions.

The objective of the claimed invention is to create a multifunctional portable device for recording vital signs and how it works, as well as reducing the time required to record and evaluate vital parameters.

The technical result of a multifunctional portable device for recording vital signs and the method of its operation is to expand the functionality while maintaining the compactness and ease of use of the device, the possibility of recording several vital signs, such as electrocardiography, pulse oximetry, photoplethysmography, thermometry, respiratory rate, followed by complex analysis of the received data.

The specified technical result is achieved due to the fact that the multifunctional portable device for recording and analyzing vital signs is made in the form of a functional block, a program block and a client device block interconnected. The functional block contains the ECG module block, the RR module block, the SpO2 module block and the temperature module block, connected with the sensor block, the microcontroller block and the power supply. The ECG module block includes 3 electrodes, which are used to contact human skin and register potential differences. The SpO2 module block allows you to capture information about blood oxygen saturation, as well as the shape of the pulse wave. The temperature module block includes a temperature sensor that allows you to measure body temperature in a non-contact way. The block of the RR module receives information about the change in electrical resistance between the two electrodes, on the basis of which the frequency of respiratory movements is calculated.

The data received from the function block is synchronized on the microprocessor block and the client device block.
