Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a biometric information management system for measuring biometric information of a user and providing information on health management of the user based on the measured value.

[0002]

2. Description of the Related Art Conventionally, when biometric information such as urine sugar level is measured, the numerical value is recorded on a recording sheet or a medical record so that the user can see it and use it for his / her own health management. . Further, Japanese Patent Laid-Open No. 10-170512 discloses a method of storing a urine sugar value and displaying it in a graph. Further, in Japanese Patent Laid-Open No. 2000-5928, the slope of a regression line representing the relationship between the measurement order and the urine sugar value is determined by the least squares method to determine whether the urine sugar value has an increasing tendency, a decreasing tendency, or a stable tendency. A urinalysis device that displays results has been proposed. In this case, the user can know the tendency of the change in his urine sugar level.

[0003]

However, in the case of a urine sugar value or a blood pressure value, which changes greatly depending on conditions such as the time of measurement and before or after a meal, even if these values are simply graphed, there is a tendency for improvement. It was sometimes difficult to judge whether or not there was a tendency to worsen. Even if a medical staff with knowledge and experience can make a judgment, it is often difficult for a general user to make a judgment. Further, in Japanese Patent Laid-Open No. 2000-5928, since the change tendency of the urinary sugar level is only notified in three ways: rising, falling, or stable, for example, when the urinary sugar level began to deteriorate is detailed. I could not know the tendency of change.

The present invention has been made to solve the above problems, and an object of the present invention is to provide a biometric information management system capable of easily and finely knowing the tendency of changes in biometric information. is there.

[0005]

[Means for Solving the Problem and Its Action / Effect] In order to achieve the above-mentioned object, claim 1 is a biological information measuring device for measuring biological information of a user, and a measurement measured by the biological information measuring device. A biometric information management system comprising: a storage unit that stores a value together with a measurement date and time; and a display unit that displays a temporal change of the measurement value stored in the storage unit, and a period setting unit that sets a predetermined period. A representative value calculating means for calculating a representative value of the measured values in the predetermined period is provided, and a change with time of the representative value is displayed on the display means. Therefore, if the predetermined period is arbitrarily set and the time-dependent change of the representative value of the period is displayed, the tendency of the change in the biometric information in the short-term span (or long-term span) can be easily known. . For example, even if there is no change every month, improvement and deterioration may be repeated every week. In this case, you can obtain your own action guideline such as that you should continue your actions in the period when improvement tendency appears.

According to a second aspect of the present invention, in the biometric information management system according to the first aspect, the representative value calculating means obtains the representative value by obtaining an arithmetic mean value or a geometric mean value of the measured values in the predetermined period. I decided to calculate. Therefore, since the average value can be obtained by a generally known algebraic method, the representative value can be easily calculated.

According to a third aspect of the present invention, in the biological information management system according to the first aspect, the representative value computing means computes the representative value by obtaining a moving average value of the measured values in the predetermined period. . Since the moving average value is not easily affected by a large change in the measured value during the period, the representative value can be calculated more accurately.

According to a fourth aspect, in the biological information management system according to the first to third aspects, the display means is
It was decided to display the change over time of the representative value in the form of a graph. Therefore, it is possible to easily visually judge whether the biometric information tends to be improved or deteriorated.

According to a fifth aspect of the present invention, in the biological information management system according to the fourth aspect, the display unit graphs a temporal change of the measured value stored in the storage unit, and the same graph is shown along with the temporal change of the representative value. I decided to display it above. Therefore, the measured value (raw data) can be confirmed on the same graph as the representative value, and the influence of each measured value on the representative value can be considered.

According to a sixth aspect of the present invention, in the biological information management system according to any one of the first to fifth aspects, the biological information measured by the biological information measuring device is a urine sugar value.
Among various biological information, the urinary sugar value is a value that changes greatly depending on the measurement time and whether it is before or after meal, but this system makes it easy to know the tendency of change. You can

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a block diagram of a biometric information management system showing an embodiment of the present invention. In FIG. 1, the measurement value measured by the biological information measuring device 10 is stored in the storage means 11 together with the measurement date and time. The user uses the period setting means 12 to set how many days the average value is to be taken as the representative value. Then, the representative value calculation means 13 calculates the representative value of the measured values in the set period, and the calculation result is stored in the storage means 11. Note that the representative value includes an arithmetic mean value, a geometric mean value, a moving average value, and the like, and the calculation method of these will be described later. The data of the measured value and the representative value are sent from the storage unit 11 to the display unit 14 (display of a personal computer or the like), and the change over time of the data is displayed as a graph.

2 to 5 are display examples of the display unit 14. In each figure, the horizontal axis is the date and the vertical axis is the urine sugar value (unit: mg /
dl) is shown. Further, the thin polygonal line is a graph showing the change with time of the measured value (raw data), and the thick polygonal line is a graph showing the change of the representative value with time. In each of the figures, the raw data is displayed together with the representative value, but only the representative value may be displayed. Further, for convenience, the urine sugar value is measured once a day, but of course, the urine sugar value may be measured a plurality of times a day or may not be measured on some days.

FIG. 2 shows a representative value calculated by an arithmetic average, and the period setting means 12 is set to take an arithmetic average (simple average) value for three days. If you look only at the raw data (thin line), the urinary sugar level is alternately displayed near 0 and near 1000, and it is difficult to grasp the tendency of change.
Looking at the representative value (thick line), it can be seen that there is a tendency that the overall value is gradually worsening. Further, it is possible to read the tendency of change in a short span, such as a worsening tendency is seen on August 7th to 10th and an improvement tendency is seen on the next August 10th to 13th. In this example, August 7th-1
Looking back on whether I was on a guarded life such as overeating and lack of exercise on day 0, I decided to continue doing this time because I did my best on August 10th to 13th, and so on. You can also get action guidelines.

FIG. 3 shows a typical value calculated by a geometric mean, and the period setting means 12 is set to take a geometric mean value for three days. The geometric mean value is the nth root of the product of n numbers, and if the data is 3, it is the 3rd root of the product, and if it is 4, it is the 4th root of the product. In FIG. 3 as well, similar to FIG. 2, the raw data (thin line) alone makes it difficult to grasp the tendency of change, but looking at the representative value (thick line), there is a tendency that it gradually deteriorates overall. Recognize.

FIG. 4 shows a typical value calculated by a moving average, and the period setting means 12 is set to take a moving average value for three days. The moving average value is obtained as follows. For example, the data strings A1, A2, A3, A
If there are 4, A5, and A6, the moving average value for every three is B1 = (A1 + A2 + A3) / 3, B2 = (A2
+ A3 + A4) / 3, B3 = (A3 + A4 + A5) /
3, B4 = (A4 + A5 + A6) / 3. In other words, the data sequence is divided into threes in order, the arithmetic mean (simple average) of each three is taken, and the divisions of threes are shifted one by one. In FIG. 4 as well, similar to FIG. 2, the raw data (thin line) alone makes it difficult to grasp the tendency of change, but looking at the representative value (thick line), there is a tendency that it gradually deteriorates overall. Recognize. Further, it can be clearly seen from the example of FIG. 2 that bad values continue during the period of August 14th to 16th and 20th to 24th.

FIG. 5 shows a typical value calculated by a moving average, and the period setting means 12 sets the moving average value for 14 days. Compared to FIG. 4 (moving average value for 3 days), the amount of change in the data is small and it is difficult to judge the improvement tendency or the deterioration tendency, but it can be seen that the direction is generally a little worse. The moving average value is unlikely to be affected even when there is a large change in the measured value during the period, and the more data there is, the more remarkable this tendency is. Therefore, when the period is set by the period setting means 12, a long period is set when a long-term tendency is desired, and a short period is set when the improvement or deterioration is to be known. And good.

FIG. 6 is an operation flow of a calculation routine for plotting an average value (representative value) on a graph. The average value (arithmetic average value or geometric average value) of a set period is taken and plotted on the graph. It shows the calculation routine to do.
Start from 20 and set the number of days you want to average at 21. For example, if "3 days" is set here, 22
At, the average value of the data for 3 days is calculated, and at 23, the calculation result is plotted on the last day of the 3 days. Then at 24,
Shift the data acquisition range 3 days behind, and at 25,
If it is determined that there is data to be calculated, 22
Go back to and calculate the average value for the next 3 days, plot at 23 and stagger at 3 for 24. Then, at 25, if there is no data to be calculated, then there will be an END of 26. As a result,
Calculated data is displayed every 3 days.

FIG. 7 is an operation flow of a calculation routine for plotting an average value (representative value) on a graph, and shows a calculation routine for taking a moving average value for a set period and plotting it on the graph. . Start from 30 and set the number of days you want to average at 31. If, for example, "14 days" is set here, the average value of the data for 14 days is calculated at 32, and the calculation result is plotted on the last day of 14 days at 33. Next, at 34, the data acquisition range is shifted one day behind, and at 35, when it is determined that there is data to be calculated, the process returns to 32 to calculate the average value for 14 days, and plots at 33. Then, shift at 34 for one day. Then, at 35, if there is no data to be calculated, then END of 36.

As described above, according to the present system, the predetermined period is arbitrarily set, and the change over time of the representative value (arithmetic mean value, geometric mean value, moving average value, etc.) is displayed in a graph. As a result, the user can easily know the tendency of changes in the short-term span (or long-term span) of biological information such as urine sugar level. In addition, if a doctor applies this system to diagnosis, he or she can easily find an item to encourage or praise in a conversation with a patient.
