  The database access unit 1 (140) reads vital data from the measuring device 150 that is external to the device of the present invention, adds / updates / deletes data, and receives an input processing command from the setting unit 130, A function for performing a procedure for accessing a table in the database 210 corresponding to the set condition and performing an input process to the table is provided.

  Here, the measuring device 150 will be described.

  The measuring device 150 is, for example, a measuring device for puncturing a subject's finger to collect a small amount of blood (body fluid) and measuring a blood sugar level (glucose concentration). An amplifying unit 520 that amplifies the electrical signal detected by the above, an electromagnetic noise detecting unit 530, a calculating unit 540 that converts the amplified analog signal into a digital signal and calculates a blood sugar level in the blood, a control unit 550, and a control Based on a signal from the unit 550, a display unit 560 for displaying a body fluid test result or a message to the operator, an input unit 570 for inputting memo contents such as meal contents and insulin infusion information, and power ON / OFF A power switch 580, a storage unit 590 for storing the blood glucose level (glucose concentration) measurement result, a power unit 600 in which a dry battery or the like is normally used, and measured and recorded A memory call switch 610 for calling a blood glucose level and an external output unit 500 for outputting data stored in the storage unit 590 to the outside are provided.

  The control unit 550 includes a CPU such as a microcomputer, a control program for the entire apparatus executed by the CPU, a ROM for recording various data, and a RAM for temporarily recording various data as a work area.

  As described above, the electromagnetic noise detection unit 530 causes the measurement device 150 of the present embodiment to react, for example, blood collected from the subject's finger with the reagent layer in the test paper, and color the reagent layer based on the reaction. Based on this degree, the degree of coloration is detected by irradiating the test paper with the blood glucose concentration contained in the blood, and detecting the reflected light intensity with the light receiving element. .

  The external output unit 500 is a hospital or a health management support that centrally manages blood glucose level measurement results stored in the storage unit 590 via an external device such as a personal computer (PC) or an information communication network such as the Internet. In the present invention, vital data is captured from the external output unit 500 to the display device 100.

In this case, the external output unit 500 incorporates a communication circuit such as RS232C. When performing infrared communication, the external output unit 500 includes an infrared light emitting element and its drive circuit.

  Next, the basic rule at the time of taking in data from the measuring device 150 will be described.

First, a confirmation dialog (not shown) appears on the display unit 120 screen as to whether the fasting blood glucose level shown in FIG. In the case of OK, it is automatically taken in, and in the case of No, it is set as which blood glucose level the user takes in. In the case of automatic capture, the first data is captured on the fasting blood glucose level side, and if the data corresponding to the fasting blood glucose level is not on the blood glucose level for 2 hours after loading, it is captured on the blood glucose level side for 2 hours after loading. . In the unlikely event that the blood glucose level is mistakenly imported, the attribute can be changed from the screen. For example, even if the blood glucose level is accidentally imported, the attribute is changed to the blood glucose level for 2 hours after loading. it can.

Next, the database access unit 2 (160) will be described. The database access unit 2 (160) receives an output processing command from the arithmetic processing unit 170, performs a procedure for accessing a table corresponding to the display period condition of the graph display function, and performs an output process from the table It has.

  Next, the arithmetic processing unit 170 will be described. The contents of the processing in the arithmetic processing unit 170 are shown in FIG.

When the display period condition is input through the operation input unit 110, the main processing unit 180 included in the arithmetic processing unit 170 uses the database access unit 2 (160) according to the display period condition input to the graph display function of the display unit 120. (Step S100), the necessary blood glucose level data is extracted from the blood glucose level table of the database 210 (step S110), and the extracted data is stored in the blood glucose level memory (FIG. 7) (step S120). Then, the data having the same blood glucose level memory ID is extracted from the data stored in the blood glucose level memory, and the calling of the sub processing unit 1 (190) and the sub processing unit 2 (200) is looped by the number of data. (Step S130) When the execution of the sub-processing unit 1 (190) and the sub-processing unit 2 (200) is completed for the number of data, the loop is finished (step S160). Further, the sub processing unit 1 (190) sets a color scheme corresponding to the range of the display period set by the setting function in the blood sugar level memory on the condition of the display period of the graph display function (step S140). At this time, a color enters the color column of the blood sugar level memory. The sub processing unit 2 (200) plots the blood glucose level memory on the graph on the condition of the display period of the graph display function (step S150).

Next, the database 210 will be described. The database 210 stores data from the database access unit 1 (140) for each corresponding table. The tables are the fasting blood glucose level table 1 (FIG. 8) and the post-loading 2 hour blood glucose level table 2 (FIG. 8). 9) There are four tables, a plotting data coloring setting definition table (FIG. 10) and a group ID definition table (FIG. 11). The table items are [a. Year / month / day, b. Hour / minute / second, c. Blood glucose level, d. Fasting / post-load sequential ID], [a. Date, b. Hour, minute, second, c. Blood glucose level, d. Fasting / post-load sequential ID], [a. ID, b. Group ID, c. Color, d. Display period], [a. Group ID, b. Group name].

  FIG. 12 shows a vital data graph display screen in the present embodiment. As shown in FIG. 12, a graph display can be selected by a radio button using an alternative. One is to display the graph in the set display period, and the other is the additional function of the display that allows you to grasp the impact of the event. By specifying a certain point in time, the plot data can be divided into before and after that point. Can be displayed. For example, if the meal is improved from January 3, 2008, it is easy to see what changes appear in the vital data from that day.

  Here, the area display means will be described. When the vital data is displayed in a graph, it is necessary to set and display the area corresponding to the vital data, for example, as shown in FIG. 12, which is divided into three areas of normal type, boundary type, and diabetes type. . In the display method, first, the display area is divided into two-dimensional coordinate X-axis (horizontal axis) and Y-axis (vertical axis), and the respective lengths are set on the program, for example, X-axis = 1000, Y-axis = 500. By defining, a display area of 1000 × 500 is completed. Next, if the X-axis 1000 = 2 hours blood glucose level 250 after loading and the Y-axis 500 = fasting blood glucose level 200 are defined, if the plot data is 2 hours blood glucose level 200 after loading and fasting blood glucose level 130, The plot is displayed with X axis = 200/250 * 1000 and Y axis = 130/200 * 500. Among them, by defining a threshold value (for example, blood glucose level 2 hours after loading <140 and fasting blood glucose level <110 = normal blood glucose level 2 hours after loading> 200 and fasting blood glucose level> 126 = diabetic type) ), The area can be displayed. The unit on the graph may be anything corresponding to the data to be displayed, and may be color-coded for each region. The display method of the area display means and the shape of the area are not limited to the present description as long as the object is achieved.

  In the above embodiment, fasting blood glucose level and blood glucose level for 2 hours after loading are adopted as vital data, and a blood glucose measuring device is adopted as the measuring device 150. However, as in the graph display screen shown in FIG. If systolic blood pressure (maximum blood pressure) and diastolic blood pressure (minimum blood pressure) are adopted, a sphygmomanometer is adopted as a measuring device (another embodiment of the present invention), etc. Any data can be used. However, it is necessary to display the adopted vital data in a graph area corresponding to the data (units, values to be used as indices, etc.), or the effects of the present invention will not be manifested unless they are made to correspond.

When the measuring device 150 is a sphygmomanometer, it includes a cuff, a cuff pressurizing / depressurizing unit, a blood pressure value calculating unit, a control unit for controlling the entire device, a calculation processing unit and a display unit (not shown).
