Description

Electronic device, method for measuring biological signs by electronic device and non-transitory computer readable media

The present invention relates generally to an electronic device and a method for measuring vital signs, and more particularly to an electronic device and a method for determining vital information from measured vital signs.

In order to increase the value of electronic devices and meet various needs of users, various application programs have been developed for execution by electronic devices.

Users can measure their own vital signs related to healthcare through electronic devices. Methods for measuring vital signs include, for example, electrocardiogram (ECG), photoplethysmography (PPG), ballistocardiogram (BCG), and impedance plethysmography (impedance plethysmography). Since heart rate measurement is non-invasive and includes various health-related information, it is considered the best measurement for mobile healthcare. By measuring heart rate, It can measure heart rate variability (HRV). Heart rate variability can be used to monitor the balance of the sympathetic nervous system and the parasympathetic nervous system of the autonomic nervous system.

When measuring heart rate variability, the calculation of the stress index generally only determines the increase/decrease of the corresponding parameter.

For example, in one measurement method, the stress can be determined by the parameters of the heart rate variability in the frequency domain. To analyze heart rate variability in the frequency domain, a minimum measurement time of two (2) minutes is required, and this required time period is not readily applicable to ambulatory healthcare devices.

In another measurement method, in addition to the stress index, the heart rate variability can also be used to calculate the fatigue index and the health index. Blood glucose level, blood pressure, temperature, and body weight can be used to replace the index, but blood glucose level, blood pressure, body temperature, and weight cannot be used to analyze heart rate variability.

In another measurement method, analyzing the frequency domain and non-linearity of heart rate variability may take five (5) minutes, and the analysis is performed by reading an ECG from memory. However, when measuring the stress index, the heart rate variability of different individuals is not reflected and the same method is applied, so individual differences are not reflected in the stress measurement.

The method described above is only applicable to on-demand products that are operated by the user with the purpose of measuring pressure. Additionally, to measure pressure, the user should remain still without any movement for a minimum of two (2) minutes or more. However, it is unlikely that no movement will occur for two (2) minutes or more, except in cases where the user intends to measure pressure.

For example, to show that two groups are meaningfully different (i.e., there is a meaningful difference between the means of the two groups), p-values < 0.05 or p-values < 0.01 are typically used condition. When the p-value satisfies the condition, the null hypothesis is released. Since the p-values of parameters in the time domain (e.g., HR, SDNN, RMSSD, and pNN50), and parameters in the frequency domain (e.g., LF, HF, TF, VLF, nLF, nHF, and LF/HF) do not satisfy the condition The p-value was <0.05 or the p-value was <0.01, thus releasing the null hypothesis that the two groups are meaningfully different. Therefore, it should be noted that there is no statistically meaningful difference between the measured values for each parameter for the corresponding time and the measured values for 5 minutes.

Correlation indicates the linear level between two groups, or whether there is a linear relationship between two groups. Positive linearity exists when the value measured by one group increases and the value measured by the other group also increases. Conversely, negative linearity exists when the value measured by one group increases while the value measured by the other group decreases. The correlation shows a linear level. Fig. 17A, Fig. 17B, and Fig. 17C illustrate that for each age range, the results of the analysis of each parameter in the time domain and the analysis of each parameter in the frequency domain based on data of different lengths are compared with The correlation between the results of the analysis of the parameters based on standard 5-minute length profiles and illustrating the results of measuring the parameters shown in Table 1 for each of the various durations according to each age range.

As shown in Table 1, in the case of the time domain parameters HR, SDNN, RMSSD, and pNN50, data lengths of 10 seconds, 240 seconds, 30 seconds, and 60 seconds had statistically similar values to the 5 minute data. In general, SDNN is related to stress, and RMSSD is highly correlated with SDNN. Therefore, vital signs can be adequately measured without distortion using RMSSD which requires 30 seconds instead of SDNN which requires 240 seconds. In addition, SDNN can be used since unconscious vital sign measurements as well as conscious vital sign measurements can be performed in a wearable device.

In step 512 , the electronic device 101 utilizes the measured vital signs to analyze changes of parameters in the time domain. In step 514, the electronic device 101 converts the analyzed parameters into vital information. The electronic device 101 may perform at least one measurement of the vital signs and analyze parameters of the measured vital signs. The electronic device 101 can analyze the measured parameters of the vital signs in the time domain and use the interval between the beats of the vital signs to analyze the changes of the parameters. HR corresponding to a parameter in the time domain may be the square root of the mean value of values produced by increasing the difference of consecutive RR intervals, and the measurement time may be in seconds. In this case, the electronic device 101 may accumulate the measured RR intervals, and measure and accumulate the RR intervals until their final sum exceeds a predetermined time. In addition, the electronic device 101 can measure and accumulate the RR interval until the number of heartbeats exceeds a predetermined threshold. The vital signs may include at least one of heartbeat, pulse, impedance plethysmography, BCG, ECG, PPG, and blood flow rate. The parameters may include HR, RR At least one of interval, SDNN, RMSSD, and pNN50. The heartbeat interval may include at least one of a RR interval, a pulse interval, and a JJ interval of the vital signs. The RR interval refers to the interval between two peaks of ECG, the JJ interval refers to the interval between two peaks of BCG, and the pulse interval refers to the interval between two peaks of PPG.

The electronic device 101 can convert the parameter into vital information by taking the natural logarithm (ln) of the reciprocal of the parameter. The electronic device 101 can use the following equation (1) to transform the analyzed parameters into vital information.

ln(1000/ P )................................(1)

In equation (1), P denotes a parameter.

In step 516 and step 518, the electronic device 101 compares the transformed vital information (eg, stress index) with the pre-stored average vital information (eg, stress index) in the same age range and outputs the comparison result. The electronic device 101 can compare the converted stress index with the stress index in the same age range as the user. The average pressure index can be pre-stored in the electronic device 101 or received from the server 106 . Through the comparison, it can be determined whether the stress index of the user whose vital signs are measured is higher or lower than the average stress index of the same age or within the same age range.

When the converted stress index is higher than the stress index in the same age range, the electronic device 101 may generate and output a guideline for reducing the stress index. When the converted stress index is lower than that in the same age range, the electronic device 101 may generate and output a guideline indicating that the stress index is low and including information beneficial to health. The guidelines may include information for reducing the stress index, notifying that the stress index is At least one of a high alarm, and a breathing method to reduce the stress index.

And analyze the respiration rate. When breathing is detected from the user while outputting the guideline, the electronic device 101 can compare the detected breath with the guideline in real time and output the comparison result.
