Description

Medical device {MEDICAL APPARATUS}

The present invention relates to a medical diagnostic device that can measure blood pressure, electrocardiogram, heart rate, oxygen saturation, etc. in a non-invasive manner based on the user's biosignals.

Common blood pressure measurement methods include auscultation (Korotkoff sound) method, oscillometric method, and tonometric method. The auscultation method is a typical pressure measurement method. In the process of blocking the blood flow by applying sufficient pressure to the part of the body where arterial blood passes, and then decompressing, the pressure at the moment when the sound of the pulse is first heard is measured as systolic pressure. , This is a method of measuring the pressure at the moment the pulse sound disappears as diastolic pressure. This auscultation-based blood pressure measurement method is easily applied by medical staff, and is a measurement method trusted by many medical staff because it has relatively high accuracy and the experience of the measurer affects the accuracy.

Oscillometric and tonometric methods are commonly applied to digital blood pressure measuring devices. The oscillometric method, like the auscultation method, measures systolic blood pressure by detecting pulse waves generated during the process of sufficiently pressurizing the part of the body through which arterial blood passes to block arterial blood flow and then decompressing it at a certain rate, or increasing the pressure of the body part at a certain rate. This is a method of measuring diastolic and diastolic blood pressure. The tonometric method is a method that applies a constant amount of pressure to a part of the body without completely blocking the blood flow in the artery, and measures blood pressure continuously using the size and shape of the pulse wave generated at this time. Conventional digital blood pressure measurement devices that use oscillometric or tonometric methods have relatively low measurement accuracy (5 to 10% error), and medical staff have lost confidence in their accuracy.

In addition, high blood pressure is a chronic disease, and continuous measurement of blood pressure is very important for early prevention, detection, and treatment of cardiovascular disease (CVD). However, the size and measurement method of existing cuff-type blood pressure monitors make it difficult to measure blood pressure in everyday life. There is discomfort. In addition, due to the rapidly increasing burden of medical expenses due to the aging domestic population and the increase in chronic diseases, as well as increased interest and demand for a healthy life, an industry for proactive preventive care is emerging.

In addition, the demand for strengthening health care awareness and developing digital, non-face-to-face biometric information measuring devices is increasing due to COVID-19.

The prior invention (Publication Number: 10-2013-0078070, Publication Date: July 10, 2013) discloses a method of remotely measuring blood pressure. More specifically, the prior invention involves remotely interconnecting a blood pressure monitor control device and a blood pressure measurement device by connecting via a wired or wireless communication network. When the medical staff enters the initial family range setting mode for blood pressure measurement, the blood pressure monitor control device performs initial pressurization. A step of controlling the pressure setting of the linked blood pressure measurement device based on the range setting mode, wherein the blood pressure measurement device pressurizes the measurement site of the patient under examination based on the control of the pressure setting of the blood pressure monitor control device, the pressure device, and the pressure. A step of detecting oscillometric and auditory biometric information through sequential operation, the blood pressure measuring device processes the detected oscillometric and auditory biometric information respectively, and then the oscillometric and auditory information with systolic blood pressure and diastolic blood pressure displayed respectively (K The final measured blood pressure value is the systolic blood pressure and diastolic blood pressure that the medical staff selects and inputs from the signal waveform data for oscillometrics and hearing provided by the blood pressure monitor control device through the display of the blood pressure monitor control device that links the signal waveform data. Configuration features including the step of storing are disclosed.

Figure 3 is a diagram showing a state in which a user holds an electrocardiogram measurement module according to an embodiment of the present invention.

Hereinafter, the description will be made with reference to FIGS. 1 to 3.

The electrocardiogram measurement module 100 of this embodiment can measure the electrocardiogram while the user holds both sides of the electrocardiogram measurement module.

It is a diagram showing the components forming the electrocardiogram measurement module and the organic connection relationship between each component, and Figure 7 shows the waveform and PPG signal for the ECG signal measured by the medical device according to an embodiment of the present invention. This is a diagram showing the waveform for .

Hereinafter, the description will be made with reference to FIGS. 1 to 7.

The housing 101 of this embodiment may include a first sensor 110 and a second sensor 120 on one side, and first ECG electrode units 130 may be formed on both sides.

As an example, the first sensor 110 may be a PPG (Photoplethysmogram) sensor. The PPG sensor is a photoplethysmography sensor that can measure PPG signals from the user. An electronic device including a PPG sensor can acquire biometric information including the user's heart rate, oxygen saturation (SPO2), stress, arrhythmia, blood pressure, etc. by analyzing the PPG signal.

The PPG sensor may include a light emitter (eg, LED) and a light detector (eg, photodiode) that emit light. The light transmitter emits light to tissues or blood vessels in the user's skin, and the light detector can collect the reflected light. Light collected by a photodetector can be converted into an electrical signal. The converted electrical signal may be referred to as a PPG signal. An electronic device can obtain biometric information such as heart rate and blood pressure by analyzing the waveform of the PPG signal.

Referring to FIG. 7, the top of FIG. 7 shows the waveform for the ECG signal, and the bottom shows the waveform for the PPG signal. With reference to the drawings, a method for calculating PTT (pulse wave transit time) based on the ECG signal and PPG signal measured by the medical device 10 of this embodiment will be described below.

The pulse wave transmission time can be calculated by calculating the time difference between the R-Peak point of the ECG sensor (electrocardiogram sensor, 3508) and the PPG B-Peak point. Pulse wave transmission time (PTT) can be calculated using the difference between the time of the ECG peak point generated by the heartbeat and the time of the maximum upslope point obtained by differentiating the pulse wave.

Pulse wave velocity (PWV) can be calculated by dividing the distance between points by PTT, and the distance between points can be calculated by multiplying the user's height by BDC (Body Correction Factor, calculated as 0.5 times the adult height).

The most fundamental change in the pulse wave velocity (PWV) associated with factors such as vascular aging and arteriosclerosis is impaired distensibility of blood vessels, and thus the pulse wave velocity increases along with a decrease in the buffering function between the aorta and other arteries. In addition, the faster the pulse wave transmission speed, the faster the reflected wave returns, and as it is added to the systolic phase of the forward systolic pulse wave, the systolic pressure increases and the pulse pressure may increase.

That is, in the case of this embodiment, the signals measured through the ECG sensor 3508 and the PPG sensor 110 are transmitted to the processor 3502 of the control module 350, the module 234 for analysis of blood pressure and blood sugar, and the signal for ECG analysis. Through the module 233, the reliability of blood pressure measurement can be increased by calculating pulse wave velocity (PWV) as an additional factor along with measuring pulse wave transit time (PTT). Pulse wave velocity (PWV) can be used to calculate blood pressure by measuring the time it takes the actual blood flow to arrive at the ejection signal generated from the heart and the PPG measurement point.

Additionally, the module 234 for analyzing blood pressure and blood sugar described above may apply an artificial neural network model. As an example of this embodiment, blood pressure can be extracted from the measured ECG and PPG data by analyzing time series changes in the spatial characteristics of the signal through an artificial neural network model, and based on this, the user's blood pressure can be predicted.

More specifically, the learning data consists of simultaneously measured ECG and PPG data, and PTT, PWV calculation values and blood pressure data using these, and is used as data to learn an artificial neural network model to measure PTT, PWV and blood pressure according to electrocardiogram and blood flow measurement. Blood pressure can be predicted by understanding the correlation with blood pressure. In other words, ECG, PPG, PTT, and PWV data sets can be constructed according to changes in blood pressure levels, and the constructed data sets can be used as learning data for learning an artificial neural network model. To analyze the correlation between ECG&PPG and blood pressure, the first artificial neural network model is Convolution Neural Network (CNN) and the second artificial neural network model is Recurrent Narula Network (RNN) or LSTM (Long short-term memory). Can be used in combination.

Meanwhile, as an example, the second sensor 120 may be a temperature measurement sensor. Therefore, the user's body temperature can be measured through the second sensor 120 while the user is in contact with the gripper 1015.

The first ECG electrode units 130a and 130b can be understood as parts that detect and amplify fine electrical signals detected from the skin when the myocardium depolarizes with each heartbeat. That is, the user's electrocardiogram can be measured by the user holding the first electrocardiogram electrode portions 130a and 130b formed on both sides of the housing 101.

Meanwhile, the housing 101 may include a charging terminal 1001. The charging terminal 1001 may be in communication with the control module 350 or the battery 3501 provided in the ECG measurement pad 300. That is, when the housing 100, the control module 350, and the ECG measurement pad 300 are all combined, the charging terminal 1001 and the battery 3501 can be communicated.

The housing 101 of this embodiment may be configured to include the sensors 110 and 120, the first ECG electrode unit 130, and the charging terminal 1001, as described above. That is, ECG and PPG measurements as described above can be performed when the housing 101, the control module 350, and the ECG measurement pad 300 are combined.

The control module 350 may include a plurality of sensors including an electrocardiogram sensor 3508 and a battery 3501 therein. The battery 3501 can supply power for driving the plurality of sensors or control modules 350 described above, and the battery 3501 is supplied to the electrocardiogram measurement module (ECG) through the battery charging terminal 1001 provided in the housing 101. 100) can be charged when coupled to the holder 15. Alternatively, of course, the sensors provided in the housing 101 can receive power from the battery 3501 through the battery charging terminal 1001.

The plurality of sensors may include a heart sound measurement sensor 3505, a body temperature sensor 3506, an acceleration sensor 3507, and an electrocardiogram sensor 3508. Heart sound measurement using a microphone is possible through the heart sound measurement sensor 3505, exercise volume can be measured using the acceleration sensor 3507 and electrocardiogram sensor 3508, and the user's body temperature can be measured through the body temperature sensor 3506. You can.

The control module 350 of this embodiment may be provided as a component of the electrocardiogram measurement pad 300.

More specifically, the ECG measurement pad 300 may include a base 302, a second ECG electrode unit 340, and a control module 350. The base 302 may be made of an elastic material so as to contact the curves of the user's body, and the second ECG electrode unit 340 may be provided on the base 302. The base 302 may be provided symmetrically on both sides with respect to the control module 350 (302a, 302b), and the second ECG electrode unit 340 is provided on at least a portion of each base (302a, 302b). It can be (340a, 340b).

The control module 350 may be coupled to the central portion of the base 302, and the second ECG electrode unit 340 may be electrically connected to the ECG sensor 3508 built into the control module 350.

With the above-described configuration, the electrocardiogram measurement pad 300 can be attached to some of the user's body parts and independently measure the user's electrocardiogram. In addition, since the temperature sensor 3506 is provided inside the control module 350, it goes without saying that the user's body temperature can be measured independently without the need to be combined with the housing 101.

As described above, the measured physical information can be processed through the processor 3502 and stored in the memory 3504, and data can be transmitted and received through the communication module 3503.

That is, as described above, the ECG measurement pad 300 of this embodiment can measure the user's ECG independently from the housing 101. And by coupling the ECG measurement pad 300 to the housing 101, the user's ECG can be measured through the first ECG electrode unit 130 provided in the housing 101, and the user's ECG can be measured through the first sensor 110. PPG signal measurement and user body temperature measurement through the second sensor 120 may be performed.

Of course, the housing 101 includes the first sensor 110, the second sensor 110, and the first electrocardiogram electrode unit 130 provided on one side, and can measure biosignals through physical contact of the user. The above-described control module 350 may be coupled to the housing 101 so that the housing 101 can independently measure the user's biosignals.

However, if the control module is provided only in the housing, the ECG measurement pad cannot be used independently, so there may be limitations in measuring the ECG when attached to the user's body.

Also, if the control module is provided in both the housing and the ECG measurement pad, it is not desirable considering the efficiency and economic feasibility of the process. This is because it is not necessary for the user to attach the pad-type module to the body while holding the stick-type module by hand in order to simultaneously perform ECG measurements, and furthermore, it may cause signal interference between devices, which may actually lead to errors in measured values. Because it can happen.

Therefore, the control module 350 of this embodiment is provided as a component of the electrocardiogram measurement pad 300 and measures biological signals while holding it according to the user's convenience, or the electrocardiogram measurement pad 300 can be removed from the housing 101. Biosignals can be measured separately.

However, the above-described example is one of the embodiments of the present invention, and should not be understood as excluding the case where the control module as described above is provided only in the housing or in both the housing and the ECG measurement pad.

Meanwhile, the electrocardiogram measurement module 100 of this embodiment allows the user to measure biosignals in various ways (grip type, attachment type) according to convenience. When the electrocardiogram measurement pad 300 is coupled to the housing 101, The user's electrocardiogram can be measured in the form of a grip, and when the electrocardiogram measurement pad 300 is separated from the housing 101, the user's electrocardiogram can be measured in a form that is attached to a part of the user's body.

Biosignals measured through the above-described electrocardiogram measurement module 100 may be calculated as data through the processor 3502 and stored in the memory 3504. And it can be displayed to the user through the display 13 through data transmission and reception between the communication module 3503 provided in the control module 350 and the communication module 211 provided in the body 10.

Additionally, the data received through the communication module 211 is stored in the memory 231, and may be systematically organized through cloud/server data communication 212 and stored on an external server.

Although various embodiments of the present invention have been described in detail above, those skilled in the art will understand that various modifications can be made to the above-described embodiments without departing from the scope of the present invention. . Therefore, the scope of the present invention should not be limited to the described embodiments, but should be determined not only by the claims described later but also by equivalents to the claims.
