Description

[0001] APPARATUS AND METHOD FOR DETERMINING TIMING OF CALIBRATION FOR BLOOD PRESSURE IN ELECTRONIC DEVICE [0002]

The embodiments disclosed herein relate to an apparatus and method for determining blood pressure calibration timing in an electronic device.

Recently, as the penetration rate of smartphones and wearable equipments of high performance has increased, services for receiving healthcare while monitoring their own vital signs in everyday life using mobile devices are increasing. In particular, a variety of sensing technologies and services are being watched for health-related figures that require steady monitoring, such as blood glucose and blood pressure.

Non-invasive methods of measuring blood pressure can include, for example, stethoscopy and oscillometry. Both the stethoscope and the oscillometric method can measure the blood pressure by applying a cuff to the upper arm of the user, pressing the blood pressure higher than the systolic blood pressure, and slowly depressurizing the blood pressure.

There is also a method of estimating the blood pressure without a cuff (cuffless method). This method uses a pulse transit time (PTT) for estimating a blood pressure using inversely proportional relationship between blood pressure and pulse wave transmission time ) And a pulse wave analysis (PWA) method (hereinafter referred to as PWA method) for analyzing the waveform of a PPG signal similar in waveform and mechanism to blood pressure.

In the case of a stethoscope method using a mercury sphygmomanometer, it is necessary to have proficient measurement techniques for accurate blood pressure measurement. There is a commercially available electronic blood pressure monitor that utilizes an oscillometric method that is easy and convenient to measure without these limiting factors. However, the volume of the electronic blood pressure monitor is large because there is an air pump that automatically pressurizes the air to the cuff and a motor that operates the pump. Therefore, portability is poor and there is a limit to continuous blood pressure measurement.

In addition, since the PTT method generally requires simultaneous measurement of ECG (Electrocardiography) and PPG (photolytic pulse wave and photoplethysmogram) signals, it is difficult to measure blood pressure with no restraint and no consciousness, The method has low accuracy because it estimates blood pressure from a single PPG signal. To compensate for this, it is necessary to calibrate the blood pressure estimated from the PPG signal to the blood pressure value of the electronic blood pressure monitor by performing simultaneous measurement with the electronic blood pressure monitor periodically as well as at the beginning. However, since it is not possible to know when the user should perform the calibration, and the rate of penetration of the electronic blood pressure monitor is low, it may be difficult to calibrate the blood pressure. If the calibration is not performed correctly, the estimated blood pressure is inevitably low.

The present invention can provide a guide for correcting each user according to the reliability of the calibration and determining the expiration time of the blood pressure calibration by indexing the reliability of the blood pressure calibration.

An electronic device according to an embodiment disclosed herein includes a sensor module, a memory, a display, and a processor, the processor comprising: an elapsed time of calibration; biometric information of a user measured through the sensor module; Determining, based on the reliability, whether an event related to the calibration has occurred, and determining, via the display, a user interface for requesting the calibration, based on at least one of: and a user interface (UI).

According to one embodiment, the sensor module 240 (e.g., the sensor module 176 of FIG. 1) may contact a portion of the body of the user to measure the blood pressure of the user from a portion of the body of the contacted user. have. For example, when the sensor module 240 includes a photoplethysmogram (PPG) sensor, the sensor module 240 measures the volume change of the blood vessel caused by the change of the blood flow volume of the peripheral blood vessel while the heart repeatedly contracts the contraction, Can be measured. The PPG sensor can measure the change in blood circulation by using the light transmittance. The PPG sensor may be composed of one or more PD (photodiode) and one or more LED (light emitting diode). LEDs can convert electrical energy into light energy. PD can convert light energy into electrical energy. When light is transmitted from the LED to the skin, the PD can detect the partially absorbed and remaining reflected light. The LED may have one or more wavelengths. For example, the LED may have at least one of infrared (IR) and visible light (Red, Blue, Green). The user of the electronic device 101 can measure the change of the blood by touching a part of the electronic device 101 having the built-in PPG sensor composed of the PD and the LED to the finger and maintaining the contact for a predetermined time or more. In the systole of the heart, the amount of light detected in the PD is increased due to the increase of blood in the blood vessels, and the amount of light detected by the PD may increase due to the release of blood in the diastole. Skin and veins do not affect changes in heart rate (DC), arteries can change and AC signals can come out. The PPG sensor can process this signal to extract various parameters (eg, the peak size of the signal, the dicrotic notch, the size between peaks, or the area ratio of the waveform) and estimate the blood pressure from the extracted parameters. The technique of measuring blood pressure using a PPG sensor can be referred to as PWA (pulse wave analysis) technology.

The acceleration sensor is capable of measuring cardiac trajectory (BCG (ballistocardiography) signal), which is the mechanical vibration of the heart. The electronic device 101 (e.g., the processor 220) measures the pulse transit time from the heart to the peripheral blood according to the ability of the blood vessel to resist, based on the pulse wave measured at the periphery and the electrocardiogram or cardiac trajectory, , PTT) can be determined. The electronic device 101 can estimate blood pressure information of a user based on a pulse transit time (PWV) method including a PTT measurement method. According to one embodiment, the electronic device 101 may simultaneously measure a pulse wave and an electrocardiogram, or simultaneously measure a pulse wave and a cardiac trajectory.

The memory 230 may be a memory, The processor 220 may be composed of at least one processor, and may be divided into a main processor for performing high-performance processing and a subsidiary processor for performing low-power processing, which are physically divided. For example, the sensor module 240 is connected to the coprocessor and can perform monitoring for 24 hours. Depending on the situation, a single processor can handle high performance and low power switching. The processor 220 may include, for example, an application processor (AP).

According to one embodiment, the processor 220 can verify the elapsed time of calibration, biometric information, or blood pressure information. According to one embodiment, the elapsed time of the calibration may mean the time after the previous calibration or the elapsed time of the calibration. Processor 220 may measure biometric or blood pressure information via sensor module 240 or store it in memory 230 (e.g., application 146) via user input. Biometric information identified through the sensor module 240 may include, for example, at least one of information measured through a BIA, a stress index, a momentum, a blood glucose level, a sleep interval, an exercise time, or an electrocardiogram. The biometric information identified in response to the user input may include, for example, at least one of a body mass index (BMI), a stress index, blood glucose, or heart rate information.

According to one embodiment, the processor 220 may determine the reliability of the calibration based on at least one of the elapsed time of the calibration, the biometric information of the user, and the blood pressure information of the user. For example, the processor 220 may apply a weight in consideration of characteristics of each of the elapsed time, biometric information, and blood pressure information.

According to one embodiment, the processor 220 can determine whether an event related to calibration has occurred based on the reliability. The event associated with the calibration may mean, for example, the moment the expiration time of the calibration is reached. The expiration time of the calibration can be determined based on, for example, the reliability of the calibration. As another example, the event may indicate whether the reliability of the calibration is below a specified threshold. The threshold value may be one or more.

According to one embodiment, the processor 220 may transmit position information of the electronic device 101 to an external electronic device via the communication module 290 and receive information related to the calibration from the external electronic device. According to one embodiment, the processor 220 may display a UI requesting calibration via the display 240. According to another embodiment, the processor 220 may request calibration via sound or vibration. According to one embodiment, the processor 220 may store data in the memory 230 or read data from the memory 230.

According to one embodiment, memory 230 (e.g., memory 130 in FIG. 1) may store instructions that processor 220 is used to perform operations of electronic device 101. In one embodiment, According to one embodiment, the memory 230 may include information related to calibration. The information associated with the calibration may mean, for example, calibration elapsed time, expiration time, or reliability. According to one embodiment, the memory 230 may include biometric information of a user, blood pressure values, or location information related to calibration.

Figure 3 shows a graph showing the reliability of calibration in accordance with various embodiments.

Referring to FIG. 3, the graph 301, the graph 302, and the graph 303 may each represent a change in reliability of calibration according to different situations. The graph shown in Fig. 3 is merely an example, and the reliability of the calibration described in this disclosure is not changed to the example shown in Fig. In the graph 301, the graph 302, and the graph 303, the vertical axis may indicate the reliability of calibration, and the horizontal axis may indicate time. The reliability of the calibration can be expressed, for example, from 0 to 1.

According to one embodiment, the reliability of the calibration may continually decrease over time as a result of changes in the user's biometric information, changes in blood pressure information, performance of the electronic device 101, or a variety of other causes. Reliability may decrease in proportion to time, or may decrease rapidly depending on the particular situation. Alternatively, the slope at which the reliability decreases may vary depending on the particular situation. For example, as shown in graph 301, the reliability of the calibration can be continuously reduced in proportion to time (e.g., elapsed time of calibration). As another example, if the weight of the user of the electronic device 101 increases sharply from 50 kg to 58 kg, as shown in the graph 302, the factor causing the rise in blood pressure may increase Therefore, reliability can be reduced. Electronic device 101 may receive an event that the user's weight has increased from an external electronic device (e.g., electronic device 102, electronic device 104, or server 108 of FIG. 1) can do. If, for example, a singularity such as blood pressure variability diverges as shown in the graph 303, the reliability may be reduced. The electronic device 101 may determine the expiration time of the calibration by measuring or estimating the reliability of the calibration by measuring the various causes described above. The expiration time may mean, for example, a time when the reliability becomes zero. Once the expiration time of the calibration is reached, the electronic device 101 may provide the user with a UI requesting a calibration.

According to one embodiment, the electronic device 101 may divide the reliability of the calibration into a plurality of stages. For example, referring to graph 301, electronic device 101 may be configured to perform steps 310 (e.g., 0.7 to 1), intermediate stage 320 (e.g., 0.35 to 7), low stage 330 ) (For example, 0 to 0.35). As reliability decreases, the level of reliability can also change. The electronic device 101 can adjust the degree to which the calibration is requested by providing different UIs to the user based on the level of confidence.

Although FIG. 3 and the embodiments described below illustrate an example of confirming the reliability of calibration of blood pressure information, other measurement information other than blood pressure information may be applied on the same principle. For example, the electronic device 101 can verify the reliability of calibration of a stress index or a cardiovascular related index. According to one embodiment, the expiration time of the cardiovascular related exponent calibration may be longer than the expiration time of the calibration of the blood pressure information, and the reliability of calibration of the cardiovascular related index may decrease less than the same time as the reliability of the calibration of the blood pressure information. ) Can adaptively manage the expiration time of the calibration according to the type of the measurement information.

According to one embodiment, the processor 220 may determine the reliability of the calibration periodically or whenever the user of the electronic device 101 measures blood pressure through the sensor module 240. [

At operation 510, the processor 220 may determine whether the determined confidence is below a specified threshold. The threshold value may be one or a plurality of threshold values. For example, the threshold value may refer to a boundary interval between the high level 310, the intermediate level 320, and the low level 330 of FIG. According to one embodiment, the threshold is set differently depending on the country in which the electronic device 101 is used, the performance of the electronic device 110, the performance of the sensor module 240, the purpose of use (e.g., medical only or wellness only) .

According to one embodiment, the processor 220 may adaptively display a UI requesting calibration based on the changed confidence. For example, lower confidence may mean that blood pressure information stored in electronic device 101 is not accurate, so processor 220 may control the radius of the geofence to increase or increase the frequency of requests. According to one embodiment, when a camera application or augmented reality (AR) application is executed in the electronic device 101, the processor 220 may display the location associated with the calibration in the form of AR on the executed application.

Figure 7 shows a flow diagram of an electronic device and an external electronic device sharing location information in connection with calibration in accordance with various embodiments. 7 may represent operations after the electronic device 101 detects an event related to the calibration, or may represent operations that the electronic device 101 periodically executes regardless of whether or not the event is detected.

For example, the position of the electronic device 101 may be determined by using a position-measurable communication module such as GPS, WPS, GLONASS, NLP or CPS, or by using a local communication module such as Bluetooth, BLE, Wi- Can be measured. According to one embodiment, the electronic device 101 may change the frequency of confirming the position based on the reliability of the calibration.

Figure 8 illustrates a user interface that provides location information related to calibration in accordance with various embodiments.

Referring to Figure 8, the electronic device 101 may display place information differently depending on the level of reliability (e.g., high, medium, or low). For example, if the step of reliability is a high step, the electronic device 101 may display the place information on the basis of the city, as shown in 801, or display the place information on the basis of the specified radius (e.g., 10 km) Can be displayed. For example, if the reliability is an intermediate step, the electronic device 101 may display the location information based on the nearby location of the electronic device 101, as shown in 802, ) Can be displayed on the basis of the location information. For example, when the reliability is low or the calibration expiration time is reached, the electronic device 101 displays the place information based on the specified radius (e.g., 1 km), displays the closest place information, It is possible to display an image for a designated place as shown at 804, as shown, from the current location of the electronic device 101 to a designated location (e.g., the nearest location). For example, if a camera application or an AR application is executed in the electronic device 101, the processor 220 can display the place associated with the calibration in the AR application on the executed application. According to one embodiment, the electronic device 101 may display detailed location information (e.g., number of layers) of the image for a given location, a wait staff, or a device provided.

According to one embodiment, the electronic device 101 can recommend the specified place information to the user without displaying a plurality of place information. For example, the electronic device 101 may recommend a location closest to the electronic device 101 as shown at 803. As another example, the electronic device 101 may recommend a location that is located in a path between a pre-stored location (e.g., home, work, church, or school).

Figures 9A and 9B illustrate an embodiment that provides location information related to calibration based on geo-fence in accordance with various embodiments. FIG. 9A illustrates an operation flow diagram of an electronic device that provides location information related to calibration based on a geofence, and FIG. 9B illustrates an operation of changing a radius of a geofence based on reliability.

The calibration may improve the accuracy of blood pressure measurement results, so that the electronic device 101 may request the user to calibrate periodically or according to certain conditions, even though no event is detected. The electronic device 101 may request calibration only if the electronic device 101 is located within a designated geofence to avoid user inconvenience caused by frequent calibration requests.

Referring to method 900 of FIG. 9A, at operation 905, the processor 220 may set the radius of the geofence for the location information associated with the calibration. For example, processor 220 may perform operation 905 after receiving location information from external electronic device 701 at operation 715 of FIG.

According to one embodiment, the radius of the geofence may be changed based on the reliability of the calibration. As the radius of the geofence decreases, the frequency with which the electronic device 101 is located within the geofence decreases and the frequency with which the user is informed is reduced. On the contrary, when the radius of the geofence increases, the frequency of notifying the user increases. For example, referring to FIG. 9B, if the reliability of the calibration is high, the processor 220 may set the geofence to a specified radius (e.g., 10 meters), as shown at 901. As another example, if the reliability of the calibration is an intermediate step, the processor 220 may set the geofence to a specified radius (e.g., 100 m), as shown at 902. As another example, if the reliability of the calibration is low, the processor 220 may set the geofence to a specified radius (e.g., 1 km), as shown at 903.

According to one embodiment, the radius of the geofence may be determined based on the number of locations associated with the calibration. For example, if the electronic device 101 is located in a region with a large number of locations associated with calibration, such as a city area, the processor 220 may set the radius of the geofence to be small. In another example, if the electronic device 101 is located in an area with a small number of locations associated with calibration, such as a suburban area, the processor 220 may set the radius of the geofence to a large value.

At operation 910, the processor 220 can determine whether the electronic device 101 has entered a radius of the set geophone. If the electronic device 101 has not entered the geofence radius, the processor 220 may repeat operation 910 without requesting calibration.

When the processor 220 detects that the electronic device 101 has entered the set geofence, the processor 220 may display a UI requesting calibration. For example, the processor 220 may display the location information related to the calibration based on the reliability, as shown in 801 to 803 of FIG. 8, based on the specified radius. As another example, the processor 220 may display detailed location information of the image, a wait staff, or a device provided for the specified location, as shown at 804.

10 illustrates a user interface that provides place information in a pop-up form associated with calibration in accordance with various embodiments.

Referring to FIG. 10, as shown at 1001, the electronic device 101 receives a user input for selecting a particular place, or in response to detecting that the electronic device 101 has entered a particular location, Related information can be displayed in a pop-up form. The information related to the place may include at least one of, for example, the type or number of devices provided, the name of the place, the waiting staff, and the telephone number.

Figure 11 shows a user interface representing the reliability of the calibration and the estimated blood pressure of the user in accordance with various embodiments.

To give a user's estimated blood pressure, a higher weight is given to the latest (updated) calibration, and previous calibration (correction) values can be applied sequentially to reduce the influence. The estimated blood pressure near the expiration time can be updated using the new calibration information. The PPG logging data can be stored on the server for a certain period of time.

Referring to FIG. 11, the electronic device 101 may display the estimated blood pressure value through the display 260 according to the reliability of the calibration. The blood pressure value may be expressed by systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), or the like. For example, as shown in reference numeral 1101, if the confidence level is high, the accuracy of the estimated blood pressure is also high, so that the electronic device 101 can display the blood pressure value with a narrow confidence interval (for example, 4 mmHg) . The electronic device 101 can display a confidence interval (e.g., 10 mmHg and 20 mmHg, respectively) as shown in reference numeral 1102 or 1103, because the accuracy of the blood pressure value is lower as the user enters the lower reliability level.

Figure 12 shows another user interface representing the reliability of the calibration and the estimated blood pressure of the user in accordance with various embodiments.

Referring to FIG. 12, the electronic device 101 can display the blood pressure value with time. The graph 1201 may indicate a determined blood pressure value each time the electronic device 101 measures blood pressure. In the graph 1201, the abscissa may represent the time or the cumulative measurement number of calibrations. The graph 1202 may indicate blood pressure values for each day (e.g., day). In the graph 1202, the horizontal axis may represent a date. In the graph 1201 and the graph 1202, the vertical axis may mean the reliability of the calibration. The electronic device 101 can display the systolic blood pressure SBP and the diastolic blood pressure DBP along the time axis via the graph 1201 or the graph 1202. [

The electronic device 101 may display the confidence interval of the measured blood pressure value differently based on the reliability of the calibration. For example, in graph 1201, the reliability of the calibration decreases over time, so the electronic device 101 can display the confidence interval broadly. When the calibration is performed at the time of reference 1210, the reliability increases, so that the electronic device 101 can narrow the confidence interval. In another example, in graph 1202, when the reliability decreases, the electronic device 101 may display SBP and DBP values relatively blurred or in different colors. When the calibration is performed at the time of reference numeral 1220, since the reliability is increased, the electronic device 101 can again display the SBP and DBP values as the previous state.

G., Electronic device 101 of FIG. 1) includes a sensor module (e.g., sensor module 240 of FIG. 2), memory (e.g., memory 230 of FIG. 2) (E.g., display 260 of FIG. 2), and a processor (e.g., processor 220 of FIG. 2, the processor being configured to determine the elapsed time of calibration, Determining a reliability of the calibration based on at least one of the blood pressure information, the blood pressure information, and the blood pressure information, determining, based on the reliability, whether an event related to the calibration has occurred, A requesting user interface (UI) (e.g., one of 801, 802, 803, or 804 in Figure 8, or 1001 in Figure 10).
