Description

[Detailed description of the invention]

[Technical Field] The present invention relates to a nutritional intake meter that calculates, analyzes and displays nutritional intake. [Background technology] First, considering nutrition, even normal healthy people need to take in balanced and appropriate nutrition. Knowledge is essential for dietary and nutritional management. Moreover, in the case of some diseases, proper dietary management is more important than drug treatment, and this dietary management is called dietary therapy. For example, in the case of diabetes treatment, the basic drug treatment is injection of insulin or administration of oral antidiabetic drugs. However, especially in middle-aged and older patients with mild symptoms and patients with glucose metabolism disorders, dietary therapy alone is sufficient to achieve the therapeutic goal. Dietary therapy is always carried out even if the patient is prescribed by a doctor. And this diet must be permanent. In addition, diseases for which dietary therapy is used include heart failure, hypertension, renal disease, obesity, etc., and the importance of dietary therapy is increasing these days. For this reason, food exchange tables are created in each country and daily menus are prepared based on them. However, by understanding the contents of the food exchange table and food composition table,
To find a meal that can meet the daily energy requirements, which vary greatly depending on gender and labor intensity, by combining more than 1,000 types of foods while maintaining a balance in the composition of each food such as protein, fat, and carbohydrates. is not an easy task, but an extremely difficult task. Currently, diabetic patients or their families
They go to the hospital or are hospitalized for at least one day to a month of experiential dietary therapy under the supervision of a doctor or nutritionist, and to understand the contents of a food exchange chart. When doctors and nutritionists provide dietary guidance to diabetic or obese patients, they take into consideration age, gender, and labor intensity, and recommend food intake for a certain number of days to ensure a balanced intake of each component of the food according to the classification of food exchange tables. The following are determined and instructed to patients as shown in Tables 1 and 2. In contrast, patients measure the amount of food with measuring cups and measuring spoons, convert the weight using a conversion table, or measure the food using a commercially available household scale and use an electronic desktop calculator to convert units and calculate energy. While doing so, he kept records as shown in Tables 3 and 4. however,
With the method described above, it is difficult to remember the weight of one unit of food (80 kilocalories), and the resolution of conventional household scales is 5g or 10g, so dietary therapy is not necessary in practice. Even those who fully understand the contents of food exchange tables and food composition tables,
When applied to each meal, it is a complicated process, so there are cases where the amount of energy (units) intake becomes inaccurate due to neglect, or there are cases where the intake of excessive food or the balance of each component is not achieved and it is unevenly distributed. Often seen.

FIG. 6 is a front view showing the code table 27 used in the nutrient intake meter of the present invention.
In accordance with the above-mentioned "Food Exchange Table for Diabetes Treatment" edited by the Japan Diabetes Society, "Table 1"..."Appendix"
Foods are classified and each classified food is given a unique three-digit code number. In other words, the number of foods belonging to "Table 1" above is 100,
For foods that belong to Table 2 above, code numbers are assigned so that the number in the table is in the 100's, such as the number in the 200s, and you can tell which category the food belongs to just by looking at the code number. It is becoming more and more common. In addition, food items belonging to the above ``appendix'' are given code numbers in the 700s. Next, the operation of the nutrient intake meter of the present invention will be explained based on a flowchart. First, the power switch SW provided on the keyboard 2 of the main body 1 is set to diet mode or sleep mode to initialize the device to each mode. When the power switch SW is now turned on to the diet mode side, the arithmetic circuit section 12 that has determined this mode setting will switch all the display sections of the display 3 through the drive circuit 16 through the initial setting processing routine shown in FIG. After lighting for the entire time, the analog display section 6 remains lit and the other display sections are turned off. At this time, among the display elements 18a made of light emitting diodes etc. provided on the keyboard 2 for guiding key input operations, the display element 18a is provided corresponding to the printed characters "Replacement table".
The arithmetic circuit section 12 lights up via the drive circuit 19 to display that the current diet mode is set to the food exchange chart mode for diabetes treatment, and then proceeds to the key input processing routine shown in FIG. Transition. At this time, "Exchange table/Nutritional value" switch key 2
By pressing the key 6r, the nutritional value mode can be set to display each nutrient such as energy, protein, fat, carbohydrates, salt, and potassium.At this time, the arithmetic circuit section 12 that monitors key inputs operates as described above. When a key is pressed, the display element 18a is turned off via the drive circuit 19, and instead, the display element 18b provided corresponding to the printed characters "Nutritional Value" is turned on. Figure 9 shows the “exchange table/nutritional value” switch key 26.
This is a mode processing routine for mode switching using r, and the flag KD is switched between O and 1 every time the "exchange table/nutritional value" switching key 26r is input, and this flag KD is to be determined. The above-mentioned display elements 18a and 18b are switched on and off by this. When the power switch SW is set to diet mode, it is normally set to exchange table mode. Next, the instruction amount that is the allowable intake amount (calories expressed in units: 80 kilocalories per unit) instructed by a doctor or nutritionist is stored in the instruction amount storage section 4. The procedure for memorizing is to first press the "instruction amount" key (26g) and set the instruction amount input mode. When this mode is set, the first thing to do is to
When the arithmetic circuit unit 12 detects that the key (26g) is turned on and the command input mode is set, it prints "Determine command amount" to alert the user that the command input mode is set. Displayed display frame 28
The display element 18c provided corresponding to point a is turned on via the drive circuit 19. At this time, the arithmetic circuit unit 12 determines whether it is the exchange table mode or the nutritional value mode, and if it is the exchange table mode, it lights up the display part <sub>292</sub> , and conversely, if it is the nutritional value mode, it lights the display part <sub>293</sub> . , informs the user whether the total unit or energy is displayed. Now, if we are in the exchange table mode, the arithmetic circuit section 12 reads out the currently stored total unit from the instruction amount storage section 10 and displays the calculation result on the display 3 via the drive circuit 16 based on the data. The total unit is displayed on the section 5c, and at the same time, the "unit" display section <sub>291</sub> is lit. If the displayed value of the total unit does not match the value of the total unit of the instruction amount, the user can change the value to the total unit of the instruction amount using the numeric keypad 26.
Input by a. This input value is displayed on the calculation result display section 5c, and the "total" display section 29 <sub>2</sub> is lit, indicating that the displayed data is the total unit amount together with the "unit" display section 29 <sub>1</sub> lit. Now, when the "desu" key 26d is pressed after the above-mentioned input, the arithmetic circuit section 12 will be activated by the instructed amount automatic distribution storage section 8a.
The total unit in the data is read out to the temporary storage register 9 and compared with the input total unit, the total unit in the instruction amount automatic distribution storage section 8a for the total unit is determined, and the total unit is stored in the determined total unit. The corresponding data of "Table 1" to "Table 6" and "Appendix" are automatically selected and read out and set in each storage area of the instruction amount storage section 10. In other words, the arithmetic circuit section 12 and the automatic instruction amount distribution storage section 8a allow the user to simply input the instruction amount in total units and calculate the appropriate amount corresponding to the instruction amounts in "Table 1" to "Table 6" and "Appendix". The values are automatically set, so even if you forget the amounts indicated in each table, you can manage your diet appropriately. Now, after pressing the above-mentioned "desu" key 26d, the display and lighting of the calculation result display section 5c, the "total" display section 29 <sub>2</sub> which is the content display section, and the "unit" display section 29 <sub>1</sub> disappear momentarily, and then the display lights up again. It turns out. Now, when confirming the stored data, the following operations are performed. For example, when modifying data in "Table 1" or confirming input numerical values, it is recommended to press the "display advance" key 26q, and when this key is pressed, the arithmetic circuit section 12 will read "Table 1" from the instruction amount storage section 10. Read the data of
The numerical value of the data is displayed on the calculation result display section 5c, and the "unit" display section <sub>291</sub> is turned on. Further, the characters "Table 1" are illuminated on the display section <sub>294</sub> . If the displayed numerical value does not match the numerical value of the instruction amount corresponding to "Table 1" instructed by a doctor or the like, the user performs a manual correction using the numeric keypad 26a. In other words, numeric keypad 26a
When a numerical value corresponding to the instruction amount is inputted using , this numerical value is displayed on the calculation result display section 5c via the driver circuit 16 under the control of the arithmetic circuit section 12. After inputting this, press "Desu" key 26.
When key d is pressed, the newly corrected value is set in the storage area of the instruction amount storage section 10 corresponding to "Table 1" by the operation of the arithmetic circuit section 12. When the data is entered in this way and the data input correction for the last "appendix" is completed and the "display forward" key 26q is pressed, the currently stored total unit is displayed in the calculation result display section 5c. It will be displayed by. In the case of a display corresponding to "Appendix", instead of displaying the contents on the display section <sub>294</sub> , the characters "Appendix" are displayed by lighting on the display section <sub>295</sub> . Now, when setting and modifying the instruction amount in the exchange table mode is completed and the "instruction amount" key 26g is pressed, the arithmetic circuit unit 12 determines this key input and changes the mode from the instruction amount input mode to the food data input mode. The display element 18c is switched off. At this time, if the printer 7 is set, the arithmetic circuit section 12 detects this and displays the total unit, numerical data of "Table 1" to "Table 6" and "Appendix" stored in the instruction amount storage section 10. interface 3
0 to the printer 7 for printing out. When manually correcting the indicated amount, if a numerical value is incorrectly entered and the total unit value does not match the sum of the unit values in each "table" or "appendix," this may indicate an input error, for example. For example, the display on the calculation result display section 5c is blinked to prompt the user to set the instruction amount again. In addition, if you want to enter the indicated amounts of energy (calories), protein, fat, carbohydrates, salt, and potassium, use the "Exchange Table/Nutritional Value"
The nutritional value mode must be set by pressing the key 26r. This switching to the nutritional value mode is also effective when inputting the instruction amount or from within the mode. Now, when you press the "Exchange Table/Nutritional Value" key 26r to change to the nutritional value mode, the display 293 corresponding to the word "Energy" lights up on the display <sub>3</sub> due to the operation of the arithmetic circuit section 12. ,
The display section 29 <sub>13</sub> corresponding to the characters "kcal" lights up,
The currently stored kcal-converted energy data from the instruction amount storage unit 5c is displayed on the calculation result display unit 5.
Displayed by c. At this time, if the displayed energy value and the energy value of the instruction amount do not match, the user makes a manual correction using the numeric keypad 26a in the same manner as the correction of the instruction amount described above. In this way, it is possible to input and correct the following instructions for protein, fat, carbohydrate, salt, and potassium. In this case, by successively pressing the "display advance" key 26q, input corrections can be made in the order described above, and the display section <sub>296</sub> displays the contents each time.
~29 <sub>10</sub> is turned on to let the user know what the display on the calculation result display section 5c shows. At the same time, "g" or "mg" indicates the unit of the numerical value displayed.
The display section 29 <sub>11</sub> or 29 <sub>12</sub> corresponding to the characters is lit. Now, when you have finished setting and correcting the indicated amount in the nutritional value mode, you can switch to the food data input mode by pressing the "instructed amount" key 26g. The arithmetic circuit section 12 turns off the display element 18c corresponding to the display frame 28a marked with "", and if the printer 7 is set, reads out the data currently stored in a predetermined storage area of the instruction amount storage section 10 and outputs the energy. , print out the numerical values corresponding to each data of protein, fat, carbohydrate, salt, and potassium. When the input of the instruction amount is completed in this way, when switching from the instruction amount input mode to the food data input mode by pressing the "instruction amount" key 26g, each data input sequentially is classified in the instruction amount storage section 10. are stored for each table and also for each composition. The above data stored in the instruction amount storage section 10 is retained even when the power switch SW is turned off by the backup battery power source. Now, when switching to the food data input mode, under the control of the arithmetic circuit unit 12, the display element 18d provided corresponding to the display frame 28b displaying the text "FOOD NO." flashes, and the user The code number of the food to be ingested is found from the code table 27 in FIG. 6, and this code number is input from the numeric keypad 26d. of this code number
The number in the 100's corresponds to the number of classification tables, and when a code number is input, the blinking display element 18d lights up, indicating that a food code number is currently being input. Further, the arithmetic circuit unit 12 displays the input food code number on the food code number display unit 5a via the driver circuit 16. When the user confirms the code number from this display and presses the "desu" key 26d, the arithmetic circuit section 12 reads out the food composition data corresponding to the code number from the food component storage section 8 into the temporary storage register 9. memorize temporarily. When this storage is completed, the display element 18d turns off, and the display element 18e corresponding to the display frame 28c in which the next "quantity" is printed blinks under the control of the arithmetic circuit section 12. This blinking indicates that the food number code input mode has ended and the mode has changed to the amount input mode. In this mode, the user can enter the amount data of the actual intake of the food they have ingested or are about to ingest. The information can be input to the arithmetic circuit section 12 using any of the following three input methods. In other words, when you know the actual amount of food ingested, press the numeric key 26e and press the numeric key 2.
6a, or if you do not know the actual amount of food ingested and want to enter it using a scale, press the "On scale" key 26n and place the food on the weighing pan 4 to obtain the actual measurement data. How to enter,
Or, I don't know the amount of fruit consumed, but 1 cup of fruit, 1 bowl of rice
When a guideline amount for a cup, a single serving, etc. is known, it is possible to select a method of pressing the "by guideline" key 26c and inputting the guideline amount using the numeric keypad 26a. First, to explain the case of using the key 26e "by numerical value", in this method, the key 26e is used "by numerical value".
When the key 6e is pressed, the display element 18e changes from flashing to lit, indicating that the user is about to input the numerical value of the current quantity. Therefore, the user uses the numeric keypad 26
When the weight value of the ingested food is input by a, the input value is displayed on the intake amount display section 5b via the drive circuit 16 under the control of the arithmetic circuit section 12, and after confirming this value, the user When the user presses the "desu" key 26d, inputting the quantity is completed. At this time, the display element 18e turns off, indicating to the user that the quantity input mode has ended. In addition, in the method using the "scale" key 26h, when the "scale" key 26h is pressed, the arithmetic circuit section 12 displays "Og" on the intake amount display section 5b and the display section 29 <sub>11</sub> based on this keystroke. let After confirming this "Og" display, the user places the food to be taken on the weighing pan 4, and the weighing section 20 measures the weight of the weighing pan 4, and this measurement data is sent to the arithmetic circuit. The arithmetic circuit section 12 that has taken in the measured data causes the intake amount display section 5b to display the measured weight value via the drive circuit 16. After confirming this displayed value, the user presses the "desu" key 26d to complete the input of the amount.
Of course, the blinking, lighting, and extinguishing control of the display element 18e is the same as in the case of numerical input. Next, if you do not know the actual intake amount, but you do know the approximate amount, first press the ``Estimated'' key 26c, and the arithmetic circuit section 12 will calculate the amount for one cup, one bowl, one person, based on the food code number input earlier. Determine whether or not it is expressed in the above, calculate the weight value (per unit of guideline amount) according to the guideline amount, then multiply by the value input from the numeric keypad 26a, and use the calculated result as the intake amount. It is something. For example, if you want two bowls of rice, first, use key 26c as a guide.
After inputting , enter the number "2" from the numeric keypad 26a, and then enter the "desu" key 26d.
The arithmetic circuit unit 12 calculates the standard intake by multiplying the pre-stored weight value per bowl by the number of bowls. Of course, the blinking, lighting, and extinguishing control of the display element 18e is the same as in each input method described above. Now, when the actual intake amount of the food that has been ingested or is to be ingested is input by any of the input methods described above, the arithmetic circuit section 12 inputs the data stored in the temporary storage register 9. Energy intake and composition intake (protein, fat, carbohydrates, salt,
The unit of intake amount for each classification of the table corresponding to the calculation result of potassium (potassium) and the exchange table mode is calculated. At this time, if the current diet mode is the exchange table mode (that is, the display element 18a is lit), the display 3 lights up the table classification of the corresponding exchange table on the display ₂₉₄ , and also displays the calculation result. The number of units is displayed on the display section 5c.
Of course, the display section ₂₉₁ also lights up, indicating that the displayed numerical value is the number of units. Now, even when displaying this calculation result, the input food code number and intake weight value are still displayed on the food code number display section 5a and the intake amount display section 5b, respectively, so that the user can check the current calculation result display section. There is an advantage that it is possible to check which food the numerical value displayed in 5c is and how many grams of intake value it is, and that the comparison of the output results becomes clear. Now, when displaying this calculation result, the arithmetic circuit section 12 blinks the display element 18f corresponding to the display frame 28d in which the word "intake" is printed, and displays the calculation result in the classification and total storage section 1.
The user is prompted to select either ``additional storage'', ``subtraction storage'', or ``no storage'' to 3. These selections are made by pressing any one of the "+ intake" key 26j, the "- intake" key 26l, and the "send off" key 26k. That is, when the "+ intake" key 26j is pressed, the operation of the arithmetic circuit section 12 classifies the calculated intake amounts of energy, carbohydrates, proteins, lipids, salt, and potassium and the number of units corresponding to the exchange table classification. The total energy and the number of units are added and stored in the storage area of the corresponding classification of the total storage unit 13, and the total energy and the number of units are added and stored in the data stored in the respective areas. Note that the display on each of the display sections 5a to 5c is in a lit state. Furthermore, when the "-intake" key 26l is pressed, subtraction is stored, contrary to the addition storage when the above-mentioned "+ intake" key 26j is pressed, and when the "send-off" key 26k is pressed, classification and aggregation are performed.

At the same time as the key is pressed, the display element 18f changes from a blinking state to an extinguished state under the control of the arithmetic circuit section 12. Then, the display element 18a changes from the off state to the blinking state again, and returns to the initial food code number input state. Returning to this state allows the user to continue inputting data and calculating nutritional values. Now, the above-mentioned "+ intake" key 26
j or the "-intake" key 26l to store the calculated data, if there is one in each table, appendix, or composition whose indicated intake exceeds the cumulative intake, the display section of the title will be displayed. This flashes to notify the user that the intake amount has exceeded the prescribed amount. If the user makes an input mistake, please click "Correct"
Of course, when the key 26b is pressed, the input data is cleared and data can be input from the beginning. In addition, to erase the contents of each component storage area of the classification and total storage section 13, use the "erase" key 26f.
This is done by pressing the key, and the user presses 1.
It is best to press the "delete" key 26f at a convenient time such as a meal or a day. Furthermore, if the printer 7 is set, the food code number and actual intake amount will be printed out when the above-mentioned "+ intake" key 26l or "-intake" key 26l is pressed. In the case of the "-intake" key 26l, a "-" sign is additionally printed in front of the actual intake amount value. By the way, as mentioned above, if there is no "send-off" key 26k, the three steps of inputting the food code number, inputting the actual intake amount, and calculating and totaling the intake amount, as shown in FIG.
In addition to the two steps, the routine indicated by the dashed line is required, and two routines are required, but
With the 26k key, you only need to perform routines with solid lines, and with a series of key operations, you can calculate the intake amount (nutritional value) of food.
This allows us to proceed with the calculation of Next, when the diet mode is set and the exchange table mode is set, the data of the instruction amount corresponding to the "total" unit number is first transferred from the instruction amount storage section 10 to the comparison operation circuit section by the operation of the operation circuit section 11. At the same time, data on the actual intake amount corresponding to the "total" is transferred from the classification and total storage section 13 to the comparison calculation circuit section 14, and the 100% ratio of the actual intake amount to the instructed amount is calculated. This calculation result is stored and held in the temporary storage register 15. This calculated data is input to the drive circuit 16, and the drive circuit 16 determines the number of scale-shaped display segments 6a on the analog display section 6 of the display 3 based on the calculated data, and lights up a predetermined number of display segments 6a. At the same time, the numbers indicating 100 percent are also lit. In other words, one display segment 6a is
It corresponds to a rate of 10%, and the number of lights to be lit is determined by rounding the calculated data up, down, or down to the nearest 10%. Therefore, the user can see at a glance the ratio of the actual intake amount to the instructed amount by lighting the display segment 6a of the analog display section 6. Note that the nutritional value mode, not the exchange table mode, uses "energy" data instead of the "total" number of units. After the user inputs the actual intake amount or estimated amount of the food that the user is taking or intending to take in this way, if the user wants to compare the intake amount so far with the instructed amount, press the "judgment" key 26n. Good. First, by pressing the "judgment" key 26n, the energy intake of the food corresponding to each classification table, the total intake for energy, the intake of protein, fat, carbohydrates, salt, and potassium are each indicated in this order. The calculation result is stored in the temporary storage register 15, and each time the "display forwarding" key 26q is pressed thereafter, the calculation result is sequentially read out from the temporary storage register 15, and a display is performed based on the result. . This display is displayed as "+", "-" in the calculation result display section 5c.
However, in the zero state where the data of the instruction amount is not stored in the instruction amount storage section 10 in advance, the result of the comparison operation is displayed without the sign "+" or "-". This means that when the user forgets that the indicated amount is zero, “+△△”
This is to avoid the misunderstanding that "△△" is a value that exceeds the indicated amount. Of course, the display in this case is the exchange table mode (when the display element 18a is lit, it is a display of "total", "Table 1" to "Table 6" and "Appendix"), and the display is in the nutritional value mode (when the display element 18b is lit). ), energy, protein, fat, carbohydrates, salt, and potassium are displayed, and when the printer 7 is set, the indicated amount is compared and judged for each mode when the "Judgment" key 26n is pressed. The result and the data of the instructed amount can be printed.Next, the operation when operating the "judgment" key 26n will be further explained based on an example.Table 5 shows the data of the actual food consumed in a day. When the data in this table is input into the nutritional intake meter of the present invention, the energy intake, total energy intake, and intake of each composition corresponding to each classification table in the classification summary storage unit 13 are calculated. The memory contents are as shown in Table 6.
