DETAILED DESCRIPTION OF THE INVENTION
A first embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an external perspective view of a maternity health management apparatus 1 according to the present invention, which mainly includes a measurement unit 2 and a display printing unit 3, and is fixed to a base plate (not shown) and the display printing unit 3 of the measurement unit 2. It consists of the support | pillar part 4 which is. The measurement unit 2 has a configuration similar to that of a known body fat scale, includes a weight measurement sensor therein, and can measure the body weight by placing a person to be measured on the upper surface of the measurement unit 2. Further, on the upper surface of the measurement unit 2, current supply electrodes 5A and 6A and voltage measurement electrodes 5B and 6B are provided to measure bioelectric impedance between both feet.
[0018]
On the other hand, the display printing unit 3 includes an operation unit 7 shown in FIG. 2, a display unit 8 for displaying input data and results, and a printing unit 9 for printing measurement results.
[0019]
2 includes a power switch 10, a tare amount setting key 11 for setting the weight of a non-measurement person's clothes, a key 12 for setting date and time, a key group 13 for setting gender and body type, data, and the like. A numeric keypad 14 for setting is provided.
[0020]
FIG. 3 shows an electrical block diagram of the maternity health management apparatus 1, which includes a control unit 15 having a microcomputer, to which the switches and keys of the operation unit 7 of FIG. A display unit 8 and a printing unit 9 are also connected. Further, from the measurement unit 2, the current supply electrodes 5A and 6A are connected to the control circuit 15 via the constant current generation circuit 16, the voltage measurement electrodes 5B and 6B are connected to the control circuit 15 via the voltage measurement circuit 17, respectively. ing. Furthermore, a memory 18 for storing data is connected to the control circuit 15, and a clock circuit 19 for generating date data such as the number of pregnancy weeks is also connected. The power supply 20 supplies power to each unit.
[0021]
Next, the operation of the pregnant woman health management apparatus 1 of the present invention will be described with reference to the flowchart of FIG. When the power switch 10 is first turned on, the control circuit 15 initializes the microcomputer, the memory 18 and the like in step S1. Next, it is determined whether or not the date and time is set in step S2, and if it is set, the process proceeds to step S4. If the date is not set, the date is set in step S3. Since the date and time setting is the same as that used in a general apparatus, detailed description thereof is omitted.
[0022]
In step S4, the display unit 8 displays "Please input the clothing weight, that is, the tare amount from the numeric keypad 14, and press the tare amount setting key 11 when the input is completed". If the person to be measured inputs 1.0 kg from the numeric keypad 14 and turns on the tare amount setting key 11, it is determined Yes in step S 5, and the process proceeds to step S 6 where the tare amount is stored in the memory 18. If the tare amount setting key 11 is not turned on in step S5, the process returns to step S4, and the display prompting the input of the tare amount is repeated.
[0023]
Next, in step S7, the key group 13 for setting the gender / body type is displayed on the display unit 8 so as to turn on the key corresponding to the subject. If the person to be measured is a male standard, for example, the standard key is turned on in the frame of the male mark in FIG. Then, the input is determined in step S8, and the process proceeds to step S9, where the data of the key that is turned on is stored in the memory 18. In step S8, the process returns to step S7 until the key is turned on, and continues to prompt the key to be turned on. Similarly, in steps S10 to S12, the age of the person to be measured is input, and in steps S13 to S15, the height of the person to be measured is input and stored in the memory 18.
[0024]
In step S16, it is determined what the key turned on in step S8 is. In this case, since it is a male standard, it is determined No, and the process proceeds to step s17. In step S17, measurement is started after confirming that the non-measuring person got on the measuring unit 2 with the toes on the current supply electrodes 5A and 6A and the heels on the voltage measuring electrodes 5B and 6B. For the measurement of the body weight, the output from the body weight sensor is taken into the control unit 15 and is calculated in step S18. On the other hand, as for the impedance, a constant current is passed from the constant current circuit 16 to the electrodes 5A, 6A, the voltage between the electrodes 5B, 6B is measured by the voltage measurement circuit 17, and the impedance is calculated in step S18 from the relationship between the current and voltage. . In step S18, the tare amount is subtracted from the measured body weight, the body weight of the subject is calculated, the body fat percentage is calculated from the impedance, the body fat percentage is multiplied by the body weight, and the body fat mass is calculated from the body weight. Is subtracted to calculate the lean body mass, the lean body mass is multiplied by an average body moisture percentage of 73.2%, and the body moisture content is calculated from the height and weight, respectively, and the BMI (physique index) is calculated. The calculation result is displayed on the display unit 8 and printed out from the printing unit 9 in step S19.
[0025]
FIG. 5 shows an example of this printout. In addition to the measurement time, personal data such as gender / body type, age, height, etc., and the results measured and calculated in steps S17 and S18 are printed.
After this display and printing, the process returns to step S4 and waits for the next data input.
[0026]
If the maternity key is turned on in step S8, it is determined Yes in step S16, and the process proceeds to step S20. In step S20, the display unit 8 displays that the expected date of delivery should be entered, and steps S20 and S21 are repeated until the date of the month / day is entered from the numeric keypad in step S21. When the scheduled date is input, it is determined Yes in step S21, and the number of weeks of pregnancy is calculated from the scheduled delivery date and measurement date data input in step S22, and stored in the memory 18 in step S23.
[0027]
In the case of maternity, the processing in step S17 is the same as in the normal case. However, in the data calculation in step S18, what is added compared to the normal case is as follows.
[0028]
The fetal body weight, amniotic fluid weight, and placenta weight are read from the gestational week from the graph shown in FIG. 6 (data is stored in the memory 18), and the fetal partial weight is further subtracted from the measured body weight obtained by subtracting the tare amount. The subtracted body weight is obtained, and the body fat percentage, fat mass, lean body mass, body water content, body water content / body fat mass (TBW / FAT) are calculated based on this body weight. The result is displayed on the display unit 8 in step S19 and printed out by the printing unit 9. An example of the printout is as shown in FIG. 7, and after correction after subtracting the weight before correction (the tare amount is subtracted) before subtracting the weight of the fetal part from the example of FIG. 5. Added BMI before correction based on body weight print, fetal body weight, amniotic fluid weight, placenta weight, body moisture / body fat mass, body weight before subtracting fetal weight (tare amount subtracted) and height Yes. The pre-correction BMI is calculated and displayed or printed in order to provide data to an obstetrician / gynecologist who determines the growth status of the fetus based on the pre-correction BMI value.
[0029]
Similarly, in order to provide the data, the non-pregnant weight is calculated from the non-pregnant BMI and the weight before correction at the time of measurement in the form shown in FIG. The subtracted weight gain may be printed or displayed. When this display / printing step S19 ends, the process returns to step S4 to wait for the next data input.
[0030]
In the maternity display, the body fat percentage is shown only as a numerical value, but the relationship between the number of gestational weeks and the appropriate fat percentage rises in the early stage of pregnancy as shown in FIG. Since it was found that it decreased slightly at the end stage, the data of this graph is stored in the memory 18, and after calculating the body fat percentage in step S18, the body fat percentage is insufficient, appropriate, excessive, etc. And the advice based on the judgment are displayed or printed, it is easy for a pregnant woman to understand the coping method.
[0031]
In addition, in the above maternity display, in FIG. 8, judgment and advice on underage, appropriateness, overage, etc. were made based on the relationship between the number of pregnancy weeks and body fat percentage, but based on the relationship between the number of pregnancy weeks and body fat mass. As in the case of FIG. 8, judgment and advice such as insufficient, appropriate, and excessive may be performed. In this case, as shown in FIG. 10, FIG. 11, and FIG. 12, the body type at the time of non-pregnancy is thin type (BMI is less than 18), standard type (BMI is 18 or more and 24 or less), obesity (BMI is more than 24). The appropriate range is different. In these figures, the center graph shows the center value of the appropriate body fat mass, the upper graph shows the upper limit value of the appropriate body fat mass, and the lower graph shows the lower limit value of the appropriate fat mass. Therefore, when the BMI during non-pregnancy is input in steps S7 to S15 in FIG. 4 and the body fat amount exceeding the above graph is measured, the display on the display unit 8 or the printout of the printing unit 9 is performed. The advice is to say that this is the preferred dietary menu with excessive body fat.
[0032]
Further, in addition to the determination of the body fat percentage and body fat mass shown in FIGS. 8, 10, 11, and 12, the BMI during non-pregnancy is input in steps S7 to S15 in FIG. As shown in Fig. 4, the body fat increase amount for each pregnancy week is calculated for each body type by BMI during non-pregnancy in step S18 in Fig. 4, and when this value is exceeded, it is displayed on the display unit 8 or printed out by the printing unit 9 Can also be printed. In this case, an obese pregnant woman has to reduce the body fat amount after 28 weeks of gestation, but if not, advice and advice to reduce it are displayed and printed.
[0033]
Furthermore, the body water content / body fat amount indicates the onset of edema or / and pregnancy toxemia in the pregnant woman at the time of measurement. As shown in FIG. 14, the body water content of a standard pregnant woman (shown as TBW in the figure) slightly increases with the increase in the number of gestation weeks in the state excluding the fetal part, and the body fat mass (Shown as FAT in the figure) tends to increase slightly with the increase in the number of gestational weeks and slightly decrease in the second trimester. However, when edema or preeclampsia develops in pregnant women, body water content increases rapidly and body fat content decreases.
[0034]
When this situation was analyzed in detail, it was found that the bioelectrical impedance decreased from the appropriate range when edema or toxemia of pregnancy developed in standard pregnant women as shown in FIG. As a result, the body water content and the body fat content calculated based on the bioelectrical impedance change. Moreover, the value obtained by dividing the body water content by the body fat amount (TBW / FAT) based on this bioelectrical impedance appears in the change of the body of the standard pregnant woman as shown in FIG. It was found that the appropriate range was exceeded more than two weeks before the judgment. Therefore, the appropriate range of body water / body fat is determined according to the number of gestation weeks, and the edema onset range (the upper limit of the appropriate range or between graph a) is set on the appropriate range. It is determined as a range of intoxication and stored in the memory 18. The result calculated in step S18 is compared with this range, and whether or not edema develops or pregnancy toxemia develops is displayed and printed in step S19. This display / printing is more than two weeks earlier than the diagnosis, and it is possible to take precautions against pregnant women.
[0035]
For example, in FIG. 16, when the calculation result exceeds the upper limit of the appropriate range, the printout of the display unit 8 or the printing unit 9 may cause “swelling may occur. Be careful not to take too much water. Display and print a message such as “Please press the button to 7-8 g or less. When the calculation result exceeds the graph a, a message such as “There is a possibility of pregnancy toxemia. Please consult your doctor.” Is displayed and printed.
[0036]
In addition, the calculation result may temporarily exceed the upper limit of the appropriate range or graph a in the daily measurement. At that time, the message display / printing “A little edema tendency appears. Please measure. "Message.
[0037]
In addition, since the appropriate range shown in FIG. 16 also changes depending on the physique at the time of non-pregnancy, as shown in FIG. 17 as the center line of the appropriate range, a lean type with a non-pregnant physique index (BMI) of less than 18, The BMI is divided into a standard type having a BMI of 18 or more and less than 24, and an obese type having a BMI of 24 or more, and the appropriate range may be set to a standard deviation ± σ of each center line. This appropriate range can be changed as appropriate depending on the judgment level of the onset of edema and pregnancy toxemia.
[0038]
Furthermore, morning sickness is likely to occur in early pregnancy and bioelectrical impedance is unstable, and edema often appears after the 28th week of pregnancy. Therefore, as shown in FIG. Onset of edema and pregnancy toxemia may be determined based on the rate of change from the value of (indicated as TBW / FAT in the figure). Note that the above reference value is not limited to the 20th week of pregnancy, and using a value when the bioelectrical impedance is stabilized leads to accurate determination. Also in this case, the calculation result may temporarily exceed the plus side or the graph b. At that time, the message display / printing is “The tendency of edema appears. Please be sure to measure continuously.” Make a message.
[0039]
In order to further improve the accuracy, as shown in FIG. 19, the determination of the body water amount / body fat amount in FIG. 16 and the determination of the change rate in FIG. "," 1 "" Edema (+): Please pay attention to the appearance of edema.Let's review your life and diet. "," 2 "" Edema (++): Edema appears. Let's be careful. ”,“ 3 ”is“ edema (++++): edema is obvious and toxicosis is suspected. ”,“ 4 ”is“ edema (++++): edema is strong. It is strongly suspected that the onset of the illness is determined, ”and the fact is displayed and printed on the display unit 8 or the printing unit 9. In this case, when the user is in the same position for a plurality of consecutive days, the position is displayed / printed, and the previous position is displayed / printed even if the position is temporarily moved to another position.
[0040]

In the second embodiment, the configuration and the electric block diagram are the same as those in FIGS. 1 to 3 of the first embodiment, and steps S24, S25, and S26 are added after step S23 in FIG. It is as follows. In this example, fetal body weight, amniotic fluid weight, and placental weight of the fetal body weight, which were estimated and automatically input according to the number of gestation weeks in FIG. The value is manually input from the numeric keypad in step S25, stored in the memory 18, and the input weight is used when calculating in step S18. Other points are the same as in the first embodiment.
[0041]
In the present invention, the fetal body weight, amniotic fluid weight, and placental weight corresponding to the number of gestational weeks are stored in the memory and calculated based on the stored data. Also good.
