Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field 1] The present invention relates to a nutritional intake meter which is a meal management device.

[Background Art 1 Stroke, cancer, and heart disease are said to be the three major adult diseases, accounting for 62% of the causes of death in Japan (1981).

Stroke and heart disease are diseases of the circulatory system, and the main causes of these are high blood pressure and arteriosclerosis. Many people who only have high blood pressure feel that all they need to do is take antihypertensive drugs, and they neglect the disease called hypertension. Especially when patients say, ``I feel safe because I am taking my medication.'' [My blood pressure is currently stable. This may be related to the fact that patients often self-diagnose the disease as 1, and there are almost no symptoms for the first few years. Many people with high blood pressure have a high intake of salt or have an unbalanced diet, but since the lifestyle of the patient is the problem, there is a need to get into their lives and try to change their eating habits. . In particular, many of the patients with hypertension are elderly, and many of them like the pattern of eating rice, miso soup, simmered dishes, and pickles.According to general surveys, they are actually consuming a considerable amount of salt. When it comes to salty foods, the intake may decrease due to reasons such as it not being tasty or not enough. They also often have other illnesses, which adds to the restrictions and makes it difficult for them to eat, and the symptoms may not be obvious or they rely solely on medication. People often fail to follow dietary and feeding regimens. Nutritional guidance is said to be difficult for hypertensive patients, especially since it takes time to change eating habits that have been in place for many years.

[Object of the Invention] The present invention has been made in view of the above-mentioned points, and its purpose is to be able to measure the salt content of food, which is particularly important among control items in dietary management, and to measure the measured salt content and symptoms. To provide a nutritional intake meter that enables nutritional guidance and meal management to be easily and accurately performed by automatically comparing the prescribed salt amount according to the amount of salt.

When you know the approximate amount for cups, - servings, etc., press the 1 key (
26c) and input the estimated amount using the numeric keypad (26a).

First, to explain the case of using the 1 key (26e) for numeric values, in this method, [When you press the 1 key (26e) for numeric values, the display element (18e) changes from flashing to lit, and inputs the numeric value of the current quantity. Show what you are trying to do. Then, the user climbs onto the numeric keypad (26m) and enters the weight value of the ingested food, and the input value is calculated by the calculation circuit? It is displayed on the intake amount display section (5b) through the drive circuit (16) under the control of the VIS (12), and after confirming this value, the user presses the ``1'' key (26d) to display the amount. This will end the input. At this time, the display element (18e) turns off, indicating to the user that the portion feeding mode has ended.

Also, ``In the method of using the 1 key (26h) on the scale, [when the 1 key (261+) is pressed on the scale, the calculator vI
The portion (12) displays the intake amount display portion (5b) based on this keystroke.
and "Og" is displayed on the display section (29z). After confirming this "Og" display, the user places the food to be taken on the weighing section (20).
), the weight of the weighing pan (4) is measured and this measurement data is taken into the arithmetic circuit section (12), and the arithmetic circuit section (12) that has taken in the measurement data is connected to the drive circuit (16). The measured weight value is displayed on the intake amount display section (5d) via. After confirming this displayed value, the user presses the [de-1 key (26d) to finish inputting the amount. The weighing process using the scale is performed by the processing routine shown in FIG. 18, which will be described later. Of course, the control of blinking, lighting, and turning off 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 want to know the approximate amount, first press the 1 key (26e) for the guideline, and the arithmetic circuit section (12) will display the food code number that you entered earlier. It is determined whether it is expressed as a cup, a bowl, a serving, etc., and the weight value (per unit of guideline amount) corresponding to the guideline amount is calculated, and then the numerical value input from the numeric keypad (26a) is calculated. Multiply it and use the calculated result as the intake amount.For example, if you have 12 cups of rice, first insert the 1 key (26c) and then press the numeric keypad (26c).
Enter the value “2” from 6m), then press the “desu” key (
26d), the arithmetic circuit unit (12) multiplies the pre-stored weight value per cup by the number of cups to calculate the standard intake. At this time, if the amount/content changeover switch SW1 is on the reference side, the input value of the reference amount is displayed, and if it is on the durum side, the weight value multiplied by the input value of the reference amount and the internally stored weight value is displayed.

Of course, the control of blinking, lighting, and turning off the display element (18e) is the same as in each input method described above.

Now, when the variance of the actual intake amount of the food ingested or to be ingested is manually input using any of the input methods described above, the arithmetic circuit section (12) temporarily stores the data stored in the node (9). is multiplied by the input actual intake to calculate the energy intake, compositional intake f#, (protein, fat, carbohydrate, salt, potassium) and the classification of the table corresponding to the conversion table mode. The unit of intake for each will be calculated. At this time, if the current diet mode is the conversion table mode (that is, the display element (18a) is lit), the display unit (29,) is displayed on the display unit (3).
The table classification of the corresponding conversion table is displayed by lighting, and the number of units is displayed on the calculation result display section (5C). Of course, the display section (29+) also lights up to indicate that the displayed value is the number of units.Even when this calculation result is displayed, the food code number display section (5a) and the intake! The input food code number and intake weight value are still displayed on the display section (5b), and the user can check which food the value currently displayed on the calculation result display section (5C) is for. There is also the advantage that it is possible to check how many grams the intake weight value is, and that the comparison of the output results becomes clear. Now, when displaying this calculation result, the arithmetic circuit section (12) [
The display element (18f) corresponding to the display frame (28d) in which the characters ``Intake 1'' are printed is blinked, and the calculation result is stored in the classification and total storage section (13). It does not memorize.The user is prompted to select one of 1. These selections are [+Intake 1 key (26D), [-Intake 1 key (26+), 1゛Send-off 1 key (26K)] This is done by pressing a key.

In other words, when the 10 intake 1 key (26j) is pressed, the calculation result of energy is
The intake amounts of protein, fat, carbohydrates, salt, and potassium and the number of units corresponding to the conversion table classification are added and stored in the storage area of the corresponding classification of the classification and tally storage section (13), and the total energy and number of units are is stored in each area and added to certain data. In addition, each display section (5a) to (5c
) is lit.

Also, if you press the [-intake 1 key (26+), -
Contrary to the addition memory when pressing the [+Intake 1 key (26j) described above, subtraction is memorized, and the [Send-off 1 key (26k)]
If you press the key, it's 5 minutes! l [The total is not stored in the storage unit (13) and the display remains as is. Furthermore, at the same time as any of the above-mentioned keys (26j), (26k), and (261) are pressed, the display element (18f) changes from a blinking state to an off state under the control of the arithmetic circuit section (12), and the first food is displayed. By returning to the code number manual state, the user can continue to enter data and calculate nutritional values. Now, the above [+ intake 1 key (
26i) or "-When pressing the Intake 1 key (261) to store the calculated data, if there is one in each table, appendix, or composition where the indicated intake exceeds the cumulative intake, the corresponding title The display part (5) blinks to notify the user that the amount of intake exceeds the specified amount.
8) stores data calculated based on the component data of common salt stored in the food component storage section (8). This data input method is to enter actual measurement data as described later, or enter the amount used as the seasoning amount using the numeric keypad <26a.
) is also available. If the user makes an input error when repeating -I-, press the [Correction 1 key (26b)].
) If you press the key, the input data will be cleared and you can enter data from the beginning. In addition, to erase the contents of the component storage area of the classification and total storage section (13), press the "Erase" 1 key (26f). By the way, it is a good idea to press the [Erase 1 key (26f).

Furthermore, if the printer (7) is set, the above
+Intake 1 key (26j) or “-Intake 1 key (261)
When the key is pressed, the food code number and actual intake amount are printed out. and 1′-intake 1 key (26
+), a “-〇 sign will be added in front of the actual intake value.If the 0 portion value is input as a guideline amount, the portion amount can be changed by setting the portion display content changeover switch SWI. It is possible to print the value as a guide or to print the number of grams converted to weight.

By the way, as mentioned above, if there is no send-off 1 key (26k), the routine shown by the broken line is required in addition to the three steps of inputting the food code number manually, inputting the actual intake amount, and calculating and totaling the intake amount, as shown in the tjS20 diagram. Therefore, two routines are required, but with the Send-off 1 key (26k), only the routine for the solid line is required, and the calculation of food intake (nutritional value) can be proceeded with a series of key functions. .

Furthermore, when the diet mode and the conversion table mode are set, first, the data of the instruction amount corresponding to one total unit is transferred from the instruction amount storage section (10) to the comparison operation circuit by the operation of the operation circuit section (11). At the same time, the data of the actual intake amount corresponding to the total 1 is transferred from the classification and aggregation storage section (13) to the comparison calculation circuit! The ratio is calculated and the result of this calculation is held in a 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) of the analog display section (6) of the display 'ac3') based on the calculated data. and display a predetermined number of display segments (
6a) is lit, and the number indicating the 100th percentage is also lit at the same time. In other words, one display segment)
(6a) corresponds to a rate of 10%, and the calculated data is 1
The number of lights to be lit is determined by rounding up, rounding down, or rounding down to the nearest 0%.

Therefore, the user can see at a glance the ratio of the actual intake amount to the instructed amount by lighting up the display segment (6m) of the analog display section (6).

In addition, in nutritional value mode, not in conversion table mode, the data for "Energy 1" is used instead of the number of units in [Total].

In this way, after inputting the actual intake amount or the recommended amount of the food that the user ingests or intends to ingest, if the user wants to compare the intake amount up to the present with the instructed amount, use the 1" Judgment 1 key (26n ).In other words, Figure 15 (aHb)
6. First, by pressing the ``Judgment 1 key (26n)'', the control moves to the judgment processing routine. Comparisons are made in the order of potassium intake with each instructed amount, and the calculation results are stored in the temporary storage register (15).
26q) The calculation results are sequentially read out from the temporary storage register (15) every time the key is pressed, and a display is performed based on the results. This display is shown in the calculation result display section (5c).
This is done by adding the signs ", '-", but 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 written as "+", '-''. It is displayed without a sign.This means that when the user forgets that the indicated amount is zero, the display as ``+ΔΔ''
This is to avoid the misunderstanding that ΔΔ" is a value that exceeds the indicated amount. Of course, in this case, the display will be "Total 1,
[Table 11 to [Table 61 and [Appendix, 1 to 1]
When in the nutritional value mode (the display element (18b) lights up), energy, protein, fat, carbohydrates, salt, and potassium are displayed.If the printer (7) is set, the "Judgment 1 key ( 26n), the instruction amount, the result of comparison and judgment, and the instruction amount data can be printed for each mode.

Next, the operation when the [judgment] key (26n) is operated will be further explained based on the embodiment.

Table 1 summarizes the data of the actual food consumed in a day. When the data in this table is input, the classification summary storage section (1

10), and at the same time the classification and aggregation storage unit (13)
The data "15°2" relating to the sum of 1 is read out to the comparison calculation circuit section (10) under the control of the calculation circuit section (12) and generated as a comparison wave W. This comparison operation is 15.2-15
The calculation result will be calculated in the form of =+0.2. This calculation result and the instruction amount data are displayed on the calculation result display (5c) of the display (3) as "+0.2" and "15.0".
is displayed alternately for a predetermined period of time, for example, every 2 seconds, and the actual intake amount is +0.2 units i! from the instructed amount! At the same time, it shows that the indicated value is 15.0 units.6 At that time, the characters ``total 1'' are printed on the display section (29,) and the display section (29,). □) lights up to show the user that the display content is [total 1r unit Jl].

Furthermore, when the display forwarding 1 key (26q) is pressed, the specified amount of data "5" corresponding to Table 1-1 is called up and input to the comparison calculation circuit section (14), and at the same time, the data "5" corresponding to Table 1-1 is input to the comparison calculation circuit section (14).
13) 1 The data "7.0" in Table 11 is read out to the comparison arithmetic circuit section (14), and the data is 7°0-5.0.
Calculation is performed in the form of =+2.0, and the calculation result and instruction amount data are displayed on the calculation result display section (5c) of the display (3).
"+2.0" and "5.0" are displayed alternately for a predetermined period of time, for example every 2 seconds, and at the same time "Table 1" is displayed on the display section (29,).
At the same time, the display section corresponding to unit 1 (29
, ) lights up. In this way, after comparing "Total 1 to [Appendix 1],"
When you press the key 6q), a comparison judgment regarding the total of 1 is performed.

In the nutritional value mode, when the [Judgment 1 key (26n) is pressed, the total energy intake is compared with the designated energy amount. In other words, the indicated amount [energy J
The data "1200" for the specified amount is transferred from the instruction amount storage section (10) by the arithmetic circuit section (11) to the comparison arithmetic circuit section (14).
The [energy] data "1216"', which is read out to the classification and total storage unit (13) by the arithmetic circuit IvIS (12), is stored in the comparison arithmetic circuit unit (14).
1216-1200=+16 is performed, and the calculation result and the instruction amount data are displayed on the calculation result display section (5c) of the display (3) for a predetermined period of time (for example, 2
seconds), and at the same time the display section (29,) corresponding to energy 1 and the display section (29+3) corresponding to rkcal I light up, indicating that the intake amount is +16 kcal.
l! 1 has passed, and at the same time the indicated amount value is 12.
It shows that it is 00kcal. Furthermore, by pressing the [display advance 1 key], protein, fat, carbohydrate,
Salt and potassium can be compared and displayed in order. In this case, the calculation result display section (5c) shows the comparison amount and the instruction amount, and the display section (29, , ) (29, 2) corresponding to rgl or r+*g, I lights α, At the same time, display sections (29,) to (29) were provided corresponding to each component.
,. ), the corresponding one lights up. Then, after 'R, when comparing and displaying potassium 1, press the display forwarding 1 key (26Q) and again [Energy 1 display (
29,) lights up and returns to the initial state. Of course, if the printer (7) is set, the results of comparison and determination in both the conversion chart mode and the nutritional value mode are printed out for each mode, and the corresponding instruction amount is also printed out. When the power switch SW is turned off after inputting data, etc., the stored contents of the instruction amount storage section (10) and the classification and total storage section (13) are retained, and the power switch SW is turned off again.
When turned on, unless the instruction amount storage section (10) is reset, the operation returns to the initial state of the food data input mode. Note that DI in FIGS. 15(a) and 15(b) is a variable.

By the way, the [Intake total 1 key (26m) is a key for comparing and selecting at the end of the day, and this [Intake total, 1
When the key (26) is pressed, the comparison mode is entered, and the deviation between the intake amount corresponding to each table and the data for each table stored in advance in the instruction amount storage unit (10) is determined by the comparison calculation circuit Ig1.
S(14), and the deviation therein (intake amount -
If the indicated amount) is positive, the corresponding display section (29
, ) (292) (29S>) and the total intake amount is displayed on the calculation result display section (5C).Of course, means such as issuing an alarm or blinking a warning lamp may also be used. If the deviation is negative or zero, the display section (29,
)(29□) (29s) remains lit. Needless to say, these operations are similar in the nutritional mode.

Furthermore, each time you press the [Display forwarding 1 key (26q), the display changes from 1 Table 11 to 1 Table 61, [Appendix 1].

Of course, the first key to press is [It goes without saying that the total intake is 1 key (26m) =! If the printer (7) is set, the results will be printed out in both the conversion table mode and nutritional value mode. This [total intake-I
The processing routine by operating the key (26m) is shown in Figure 16 (
It is shown in a) and (b), and DI is a variable.

Furthermore, the food composition for calculating the intake amount in each example may of course include compositions of vitamins, calcium, iron, etc. in addition to the three major nutrients.

Next, the use of the [Salt 1 key (26p)] will be explained.

"The salt I key (26p) is an effective key in diet mode and nutritional value mode, and this [salt 1 key (26p)
When p) is pressed, the process jumps to the processing routine shown in FIG.

In other words, the arithmetic circuit section (2) detects this key press and immediately shifts control to the display mode for the amount of salt (salt), regardless of the current display state of the calculation result display section (5c).

First, if the salt 1 key (26p) is pressed for the first time,
The data of the total salt amount stored in the classification and total storage unit (13) is read out, and the read total salt amount is displayed on the calculation result display unit (5c).
The display section (29,) with the characters "rgl" on it is lit up, and the display section (29□) corresponding to rgl is lit up to show the amount of salt. ``If the salt 1 key (26ρ) is pressed again, the mode becomes sodium display mode, and the arithmetic circuit section (12) calculates the sodium amount from the salt amount data read out from the classification and total storage section (13), and calculates the sodium amount. is displayed on the calculation result display section (5C).In other words, the amount of salt is the amount of salt = amount of sodium x2,54/1000
Therefore, the amount of sodium = amount of salt x 100
The result is O/2.54, and this calculation can be performed.

In this sodium display mode, the display section (29+4) marked with the characters ``sodium 1'' is set to α light and the ra
g The display section (29+2) corresponding to l lights up to show that the amount of sodium is displayed.
It may be. Furthermore, if the salt 1 key (26p) is pressed for the third time, the currently stored amount of salt is read out from the salt storage unit (54), and the calculation result display unit (5c) is read out.
) and the display section (291+) corresponding to rgl are turned on to display the salt content. The next operation is performed by the next key pressed. In other words, the numerical data entered when the numeric keypad (26g) is pressed is determined as the amount of salt, and at the same time as the 1 key (26d) is pressed, the calculation result display section (5C) and the display corresponding to [gJ Part (29I+
) to display the input salt content.

If there is no correction here, the user must press r + intake 1 key (26N
Alternatively, the input salt amount can be added to or subtracted from the salt amount data currently stored in the salt amount storage section (54) by pressing the ``- intake 1 key (26+).

Of course, at this time, the salt data stored in the classification and total storage section (13) is rewritten. If you do not want to add or subtract the entered salt content to the salt content memory (5/I), or if you want to make a correction, press the
6k). In this case, the currently stored salt content remains unchanged. Instead of pressing the keys on the numeric keypad (26a) mentioned above, as shown in Fig. 22, place the food to be measured X in the weighing section (20) [(4) for which the weight of the tare is known*MY]. , put the probe (52) of the salinity meter body (51) into the food
nd), the arithmetic circuit section 12 calculates the actual measured value of the salt content of the food to be measured X based on the salinity measurement data and the weight measurement data, and enters a mode in which the calculated salt content is used as manual data. Now, if you press the ``Judgment 1'' key (26n) instead of the numeric keypad (26a) or [1 key (26d), the specified amount of salt will be read out from the specified amount storage section (10) and displayed on the display section (29,). , (29□) are lit, and at the same time, the difference between the stored salt content in the salt content storage unit (54) and the commanded amount is calculated, and the calculation result is displayed on the calculation result display unit (5c).

Next, [Display feed 1 key (26g) is inserted, or [10 intake 1 key (26i), [- intake 1 key (261)]
Or, by pressing the [Send-off 1 key (26k), etc., you can exit from the repeat mode of the "Salt" key (26p) and return to the original display mode. - When calculating the amount of sodium for g1 display, the amount of salt is multiplied by 1000. In FIG. 17, SK indicates [salt, 7 lags of pressing the 1 key (26p).

Next, the operation when the power switch SW is turned on to the weighing mode will be explained. This scale mode is for using this nutrition intake meter as a scale, and when the power switch SW is first turned on to the scale mode, the arithmetic circuit section (12) is connected to the display via the drive circuit (16). (3
) of each display section of the calculation result display section (5c).
# is displayed and after an initial display is made with the 7 segment portion of display 1 (29,) as 'U''', all other than the 1st digit "0" display of calculation result display M (5c) is turned off, The above-mentioned display on the display section (29,) is maintained, and this display indicates that the scale is in mode.Now, before the user places the object to be weighed on the weighing pan (4), When the start 1 key (26o) is pressed, the arithmetic circuit section (12) will always perform zero point correction as an initial setting.After this setting, press [Weighing start 1] as necessary.
Zero point correction can be performed by turning the key (26o) on, but there is no need to turn it on every time a measurement is made. Now, when the weighing section (20) starts operating and the object to be weighed is placed on the weighing pan (4), the weight data corresponding to the object to be weighed is sent as a digital signal to the arithmetic circuit section (12) to the weighing section ( 20), and the weighing results are displayed on the calculation result display section (5c) under the control of the arithmetic circuit section (12). The display section (29, I) corresponding to 1 is lit, indicating that the display is a weight value. While using this scale, if you want to weigh the net amount of the contents by excluding the weight of a container such as a bowl, plate, or cup, you can use the Tare 1 key (26i). Press the 1 key (26o) to place the container on the weighing unit 1111 (4), and after the weight of the container is displayed on the calculation result display section (5c), press the [Tare 1 key (26i)]. After that, remove the container on the weighing pan (4) and set the display on the calculation result display section (5C) to "0".
Then, when the container is filled with contents and placed on the weighing pan (4), the arithmetic circuit section (12) calculates the weight of the container memorized when Tare 1 key (26i) is pressed. The weight value of the contents can be displayed on the calculation result display section (5c) by subtracting the data and converting it into the weight value of only the contents. Therefore, the user presses the "Weighing Start 1 Key (26o) and [Tare 1 Key (26i)"]
You can find out the weight of the contents of the container by Of course[
It is only necessary to input the scale star N key (26o) when setting the memory data at the time of tare weight subtraction to "0".
It is not necessary to insert the key (26o). Also, when in diet mode, [When pressing the 1st key (26h) on the scale, the first
Jumping to point B on the 70-chart in Figure 8, weight value input processing is performed, and in this case, pressing the ``1'' key (26d) is required at the time of data setting, as shown by the broken line. The use of the tare 1 key (26i) is also effective when inputting the intake amount on the scale in diet mode. Also, when pressing the Tare 1 key (26i), the display section (2
9,) flashes the "u" display to indicate that taring is in progress.

Next, the operation of the voltage detection circuit (17) will be explained. This voltage detection circuit (17) detects when the power supply B voltage decreases and the MPU
(21) is not operating normally, and incorrect results are displayed, preventing the user from trusting the results without knowing 1]: This is to always keep the power supply B voltage. When the monitor l1 detects that the power supply B voltage has fallen to a predetermined level, it sends the detection output to the arithmetic circuit unit (12) consisting of the MPU (21). When the arithmetic circuit unit (12) receives this detection output, it causes the display elements (18d), (18e), and (18r) to blink simultaneously via the drive circuit (19), and also causes the other display elements (18m, 18b, and 18e) is turned off, and each display section is turned off via the drive circuit (16) to notify the user of the drop in the power supply B voltage. Of course, these display elements (18d) (18e) (18f
) may be flashed and at the same time a buzzer or the like sounds to reliably notify the user of the drop in power supply B voltage. Furthermore, in addition to notifying the user of the voltage drop in the power source B, even when other abnormalities occur in the device, the user may be informed of the occurrence of the abnormality using a similar display method.

Next, when the pressing of the "Date" key (26s) is determined by the arithmetic circuit unit (12) in the key manual processing routine shown in FIG. 8, the process jumps to the 70-chart shown in FIG. is done. That is, [Date, 1 key (26s)
When the key is pressed, the input on the numeric keypad (26a) can be accepted, and when any number is entered using the numeric keypad (26a), such as a date including a decimal point, the input is displayed on the calculation result display section (5C). The number you entered will be displayed.
After confirming the entered numbers, press the ``Desu 1'' key (26d) and if the printer (7) is set, you can print out the [84 size].
The role of the key (26s) is to use it as a memo of not only dates but also medical record numbers.
