Especially in the case of delicate diet and lack of exercise, such as high cholesterol, high blood pressure and cardiovascular diseases, it is a great concern for health of modern people.

In the case of hypertension, the condition is frequently seen due to poor lifestyle habits, and the execution of blood pressure management becomes very important, but the blood pressure value used as an index for health management is likely to change depending on the living environment, current behavior, mood, or stress. Therefore, when measuring blood pressure, there is a concern about the accuracy or effectiveness of each blood pressure measurement.

Many electronic blood pressure meters are available on the market, but most of them measure and display once, or provide measurement history, and the measurement results of blood pressure values are more, so that these blood pressure data are difficult to be used as the basis for the judgment of doctors. In addition, a few electronic blood pressure meters can calculate the average blood pressure value according to the measurement history records, however, if any blood pressure value has a large error due to some factor, the average blood pressure value loses the reference value.

Therefore, the electronic sphygmomanometer has the following problems and disadvantages to be improved when in use:

firstly, the blood pressure cannot be effectively managed by only measuring the current blood pressure value or recording the blood pressure value every time.

Secondly, the calculation of the average value of the blood pressure causes no reference value of the final result due to one measurement error.

Third, the blood pressure data source generally reminds the user of measuring the quantity or regularly, the measuring result is not objective, and the error is easy to generate due to the environmental factor.

Wherein the measurement sample is one of systolic pressure, diastolic pressure, maximum systolic pressure, minimum diastolic pressure, or a difference between systolic pressure and diastolic pressure.

The structure of the present invention can be understood from the above description, and according to the corresponding coordination of the structure, the advantages of increasing blood pressure data for disease diagnosis and clinical analysis help can be further enhanced by calculating the blood pressure variance, and the detailed description will be described below.

Referring to fig. 1 to 6, it is shown from the structural block diagram to the usage state diagram (two) of the preferred embodiment of the present invention, when the above components are combined, as can be clearly seen from the drawings, in order to improve the stability and accuracy of the blood pressure value source of the present invention, the user can fix the electronic sphygmomanometer 3 on the surface of the human body by using the fixing strap 31, so as to facilitate the detection portion 11 of the variance calculation module 1 to measure the blood pressure, and because the present invention needs data of a plurality of measurement samples, the user can set the first detection time of the detection portion 11 by the starting time setting portion 22 according to personal habits, set the number of times to be executed by the current detection action by the measurement time setting portion 23, and set the interval time length of each detection by the timing measurement unit 2, thereby, the power supply element 32 keeps on standby for 224 hours by cooperating with the full-time standby portion 21, so that the user can continuously record the blood pressure value within a short time of 24 hours, or continuously record the blood pressure value twice a day and at least 12 times a week (or 3 times a week and at least 12 times a month and other time intervals) as a household blood pressure variance recorder.

In actual use, as shown in fig. 4 and 5, taking six detections at 24 hours a day as an example, the detecting unit 11 may measure and generate a plurality of measurement samples (BPi), the sample counting unit 12 may generate a sample number (N) according to the number of detections of the detecting unit 11, and the average value calculating unit 13 may sum up the measurement samples and divide the sum by the sample number to calculateGenerating a sample average value (Avg), calculating the difference between each measurement sample and the sample average value by the average difference calculating section 14 to generate a plurality of sample average difference values (BPi-Avg), and adding the square sums of the sample average difference values by the sum total calculating section to generate a sample sum total value (Σ (BPi-Avg)²I = 1 ~ N), and finally, the total sample value and the number of samples are read by the output unit 16, and the total sample value is divided by the number of samples, thereby calculating the blood pressure variation number.

The measurement sample is one of systolic pressure, diastolic pressure, maximum systolic pressure, minimum diastolic pressure, or a difference between the systolic pressure and the diastolic pressure, so that the blood pressure variation number can also correspond to different measurement samples to generate different blood pressure variation numbers, as shown in the following table. Therefore, a doctor and other professionals can judge whether the blood pressure data measured by a user (a tested person) is worth reference or not according to the measurement samples and the blood pressure variation numbers, even can simply judge whether the measurement samples have data which are not suitable for reference and have overlarge deviation of measurement results, and then screen and filter the data so as to screen and screen valid and invalid data through the blood pressure variation numbers generated by the variation number calculation module 1, and further provides more accurate, more effective and more reference blood pressure data through the invention, so that wrong diagnosis and analysis caused by wrong and deviated blood pressure values can be avoided, and the help for disease diagnosis and clinical analysis is greatly improved.

Type of blood pressure	Blood pressure value (measurement sample) for each time period	Blood pressure variability
			Systolic pressure	70、90、100、110、100、90	155.56
Maximum systolic pressure	65、100、110、125、115、95	363.89
			Diastolic blood pressure	70、75、80、55、80、65	75.06
Minimum diastolic pressure	60、70、75、80、75、60	91.67
			Difference between systolic and diastolic blood pressure	10、25、25、35、25、30	58.33

Taking the systolic pressure as an example, when the measured samples are 70, 90, 100, 110, 100 and 90 respectively, the number of the samples is 6, the average value of the samples is (70+90+100+110+100+90)/6 = 93.33, and the average difference value of the samples is (70-93.33 = -23.33, 90-93.33 = -3.33, 100-93.33 = 6.67, 110-93.33 = 16.67, 100-93.33 = 6.67 and 90-93.33 = -3.33 respectively, so that the total value of the samples is (-23.33)² + (-3.33)² + (6.67)² + (16.67)² + (6.67)² + (-3.33)²= 933.33, the blood pressure variation number is 933.33/6 = 155.56.

Furthermore, according to the user's requirement, the variance coefficient calculating section 161 of the output section 16 divides the square root of the blood pressure variance by the sample average value to calculate and generate a blood pressure variance coefficient, so that the relative variance of each measurement sample can be found by using the blood pressure variance coefficient to compare the data dispersion situations with different units or the same unit but with large data variance.

In addition, as shown in fig. 6, the variance calculating module 1 can also store the measurement result in a cloud server 4 through a wireless communication module 33, so that a professional (such as a family physician) can remotely view the blood pressure data, the variance of the blood pressure, and the blood pressure variance coefficient, thereby obtaining the health condition of the user in real time.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the scope of the present invention, therefore, the present invention should be construed as being covered by the appended claims and their equivalents.

In summary, the method of the present invention can achieve the efficacy and purpose of calculating the blood pressure variance.
