Description

DETAILED DESCRIPTION OF THE INVENTION

Industrial applications

The present invention is a kind of a so-called health management support system in medical treatment using a computer, and is a computer display system which is easy to understand for ordinary people and makes it possible for the person to evaluate and determine blood pressure.

The visual computer display system related to the explanation of blood pressure and the health guidance, including the health management support system at a health checkup, etc., simply displays the blood pressure value itself in a certain graph or a line graph. In contrast to such a conventional so-called linear display of blood pressure, the systolic and diastolic blood pressures are plotted on the horizontal axis and the vertical axis on the systolic-diastolic blood pressure plane, respectively. In other words, based on a two-dimensional display of blood pressure, the determination area is color-coded according to the determination signal color corresponding to the determination, and the scale of the vertical and horizontal axes is changed according to the determination area, so that the area of the determination area is balanced and easy to read. There has been no computer display system that outputs a display diagram that makes it easy to visually grasp the meaning of medical judgment / evaluation of the input blood pressure by adding a device for performing the above. In addition, in the conventional linear display, it was difficult to understand with an image in order to read the cardiovascular characteristics of blood pressure.

Problems to be solved by the invention

In the case of the computer display system according to the prior art, the medical evaluation and determination of blood pressure can be performed by any party, whether it is the instructor or the instructor using the blood pressure. I couldn't really tell if it was on the ground. That is, for both of them, the position of the blood pressure value had to be imagined and understood by himself / herself, and it was difficult to recognize the position of the blood pressure value with a real feeling. Also, it was difficult to understand simply by the criminological display in understanding the cardiovascular characteristics of the blood pressure.

In particular, it is difficult for the general public receiving health care guidance to obtain an accurate understanding of the results, and it is difficult for them to be fully aware of the importance of the results, and it is tasteless and dry. Moreover, the results of the judgment and evaluation are provided unilaterally by the services of the medical person, and cannot be obtained by the subject alone in principle.

The present invention has been made in view of the above-mentioned problems of a conventional computer display system of this type, and has as its object the purpose of medical judgment on blood pressure values, those who provide guidance on evaluation, Of the results can be understood with a real sense of the position of the results, and especially for those receiving guidance, there is a need for accurate understanding and importance of the results. A sufficient awareness can be given effectively, and a computer display that is more realistic can be provided. By displaying a specific position based on a determination area set based on a determination criterion, it is intended to assist a viewer who understands the position.

Means for solving the problem

ソ フ ト ウ ェ ア In order to achieve the above object, the software for operating the computer display system of the present invention has been completed. The display screen has two screens and is a color display diagram, and each screen has a function of printing out using a printer.

Action

It takes a considerable amount of time and effort for humans to display similar display drawings by handwriting.However, the realization of this software allows the screen display on the computer display to be instantaneous and the printout drawings to be obtained in a short time. Became possible.

血 圧 The blood pressure display diagrams according to the first to fifth aspects are provided with two types, a total blood pressure display and a hypotension display. In the former, the systolic blood pressure values are bounded at 90, 140, 160 and 180, and the diastolic blood pressure values are bounded at 90, 95 and 100 to form a region segmentation, and in the latter, the systolic blood pressure values are , 50, 70, and 90, and the area segment is provided by drawing a borderline on the diastolic blood pressure value 50 only in the area of 70 or more and less than 90 (these decision categories are WHO and Nippon Cardiology). It has been set with reference to the criteria of the Management Research Council and various cardiovascular diagnostic books.) For convenience, in the former and the latter, the area on the display diagram where the diastolic blood pressure exceeds the systolic blood pressure is cut and distinguished as a non-existent area. In the whole blood pressure system display, when the systolic blood pressure value is 140 or more and the diastolic blood pressure value is 90 or more, the scales of the scales are three times and five times long, respectively, so that a sufficient area is provided for the segmented area. Consideration is given to equilibrium. When the input blood pressure value belongs to low blood pressure, the low blood pressure system is displayed by first displaying the whole blood pressure system and then viewing the low blood pressure region in detail.

In the computer display system according to claims 1 to 5, since the blood pressure is instantaneously displayed as a two-dimensional position in the determination area, it is possible to determine what characteristics the blood pressure has in terms of cardiology and is evaluated. You can understand with an image. For example, a disease called hyperthyroidism is characterized in that hypertension of diastolic blood pressure is relatively higher than that of systolic blood pressure. Therefore, in the present computer display system, the plot point is located farther than the “balance line” according to the claim, regardless of the level of the systolic blood pressure, and is positioned closer to the boundary with the non-existing area. Tend to occur. In this way, a computer display system can be provided that enhances the diagnostic value of capturing the characteristics of the input blood pressure.

In the "multiple blood pressure plot chart" according to claim 5, since the straight line with the radius drawn for each plotted small circle is drawn with a constant slope every time a new small circle is plotted, Even when there are a plurality of blood pressures that are the same for both the systolic pressure and the diastolic pressure, it can be understood how many input blood pressures having the same value overlap the plot point. In addition, since the angle number of this squealing is not a divisor of 360 (usually set to 33 °), it is devised so that there is no overlap even if it returns to the vicinity of the original angle after one rotation, and is distinguished. ing. In addition, since each small circle blinks in the order of the input, the progress of the input blood pressure and the change with time can be grasped on the screen.

Examples will be described with reference to the drawings. Note that, in the form of the patent application drawing, the drawing is not a color display drawing but is printed out using a monochrome printout function.

FIGS. 8 and 9 are “blood pressure display diagrams” according to claims 1 to 4 (FIG. 8 is further distinguished as “all blood pressure display” and FIG. 9 is “low blood pressure display”). In FIG. 8, the systolic blood pressure (in the figure, the term "systolic blood pressure" is used in agreement with this) is 186 mmHg, and the diastolic blood pressure (in the figure, the term "diastolic blood pressure" is used in agreement with this). 9) shows 92 mmHg, and FIG. 9 shows the output in an input example of 86 mmHg and 46 mmHg, respectively. The horizontal axis scale values are 186 and 86, and the vertical axis scale values are 92 and 46, and straight lines I1 and I2 parallel to the vertical axis and the horizontal axis are drawn. You can see that it expresses blood pressure. In the former, the intersection is in the area of "medical need 3" in the area division, and in the latter, "hypotension (2) (abbreviated as" low-(2) "in the figure)." It can be understood that it belongs to the area. Moreover, it can be seen that the plot point displayed as the former characteristic is positioned farther away from the “balanced line” and closer to the horizontal axis which is the systolic blood pressure axis. Thus, it can be seen that the same blood pressure has a characteristic that the systolic blood pressure increases more than the diastolic blood pressure. Incidentally, this example is an input example showing that the system is useful for diagnosis of hypertension in a type that occurs in arteriosclerotic hypertension.

FIG. 15 shows an embodiment of the “multiple blood pressure plot” according to the fifth aspect. A plurality of small circles representing blood pressure values are drawn in the determination section area of “medical need 3”. In this case, five small circles in which blood pressure values of five cases are plotted are displayed. Straight lines corresponding to the radius are written one by one with different inclinations on each small circle, but two straight lines i and j are written only on the small circle P. Therefore, it can be understood that this blood pressure value is plotted twice, that is, there is a set of identical blood pressure values. Moreover, it is possible to know the order of the blood pressure plot by following the writing straight line of each small circle in the order of the angle. This is useful for knowing changes in blood pressure over time.

The invention's effect

Since the present invention is configured as described above, the following effects can be obtained.

In the computer display system according to the third aspect, the systolic blood pressure and the diastolic blood pressure are not individually understood, but are expressed as intersections of straight lines having the same blood pressure values as the coordinates of the horizontal axis and the vertical axis, respectively. Thus, the blood pressure can be understood as a system in which the two are visually combined into one because the two can be regarded as one combined.

In the computer system according to the fourth aspect, it is possible to visually and directly grasp what kind of divided area the blood pressure expressed as the intersection belongs to, and to adjust the scale of the vertical and horizontal axes. In order to avoid breaking the area balance of the divided regions, the display is easy to understand and cheap. Furthermore, the systolic and diastolic blood pressure equilibrium lines are displayed, and the positional relationship of the blood pressure plot points (small circles) with respect to the systolic and diastolic blood pressure equilibrium lines allows the user to know the balance between the systolic and diastolic blood pressures. That is, as the distance increases above this line, that is, as it approaches the horizontal axis, which is the systolic blood pressure axis, the degree of increase in the systolic blood pressure increases, and conversely, the distance decreases below the equilibrium line, and the diastolic blood pressure increases. Understand that the closer to the vertical axis, the higher the degree of increase in diastolic blood pressure, and the closer to the equilibrium line, the more balanced the increase in systolic and diastolic blood pressure. To increase the diagnostic value in diagnosing cardiovascular disease.

In the computer system according to the fifth aspect, it is understood how the input plurality of blood pressure groups are distributed with respect to the determination section area, and further, the positional relationship between the input blood pressure groups and the input order. be able to. For example, if the input order is the temporal order of the measured blood pressure group of one case, it is possible to understand how the blood pressure of the case is distributed in time series on the blood pressure display diagram. it can.
