DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a health management guideline advice device which provides useful guideline information for health management such as energy metabolism based on a measured body impedance value.

[0002]

2. Description of the Related Art As a conventional health management guideline advice device, there is a device which measures body impedance and provides health management guideline information such as a body fat percentage, a body fat mass, and a lean mass based on the measured impedance value. Was.

[0003]

However, health management guideline information such as body fat percentage has generally been observed over a relatively long period of time ranging from several days to several weeks or months. For this reason, it is sufficient to select and measure at an appropriate time during the day, and it has not been possible to use the device close at hand to measure several times a day to check the health condition such as physical condition.

On the other hand, since body impedance changes during the day due to changes in dilatation and contraction of peripheral blood vessels, etc., if measurement is performed many times a day, the results differ depending on the measurement time points and the body fat percentage There is a possibility that this may be one of the error factors when calculating the values.

The present invention has been made to solve the problems of the prior art, and an object of the present invention is to provide a health care guide that can provide more various health care guide information based on a measured body impedance. An object of the present invention is to provide a management guideline advice device.

[0006]

In order to achieve the above object, a first aspect of the present invention comprises a converting means for converting a measured value of a body impedance into guide information useful for health management, In a health care guideline advice device that provides useful guideline information for health management based on the guideline information, the guideline information includes at least a metabolic state index indicating a metabolic state.

[0007] Measurements of body impedance change within a day. One of the factors of such circadian changes is a change in dilation / contraction of peripheral blood vessels. Dilation of peripheral blood vessels
Although the contraction change is proportional to the change in blood flow, there is a causal relationship between the change in blood flow and the change in oxygen supply and heat dissipation that promotes metabolism. Therefore, it is considered that the metabolic state can be estimated by measuring the body impedance. If the metabolic state is expressed by some metabolic state index, and the relationship between the metabolic state index and the measured body impedance is defined by a mathematical expression or the like, the measured body impedance value can be converted by the converting means including arithmetic means including storage means. Can be converted to indicators. By providing such a conversion means, a metabolic state index can be provided as health management guideline information.

[0008] By converting the body impedance measurement value to obtain a metabolic state index, a change in the metabolic state is estimated based on a daily change in the body impedance measurement value which may be an error factor when calculating a body fat percentage or the like. can do.

Further, since the metabolic state changes even in a short time interval of less than one day, it is possible to observe whether or not metabolism is properly performed based on the metabolic state index obtained by converting the measured body impedance. It can also be used to check the physical condition such as physical condition at hand.

[0010] The metabolic state changes depending on the behavior in the life of the subject. That is, since the change in the metabolic state reflects the lifestyle, observing the metabolic state through the metabolic state index enables the lifestyle to be recognized and grasped, which can be used for improving the lifestyle.

As the measured body impedance, there may be provided an impedance measuring means for measuring the body impedance, and the body impedance measured by the impedance measuring means may be used, or the body impedance measured by another measuring device or the like may be used. A value may be used.

According to a second aspect of the present invention, in the first aspect, the conversion means calculates the body impedance by using a conversion formula obtained by a regression analysis including at least the body impedance measurement value and the metabolic state index as variables. The method is characterized in that a value is converted into the metabolic state index.

The conversion formula of the measured body impedance value to the metabolic state index is expressed in various forms such as a mathematical expression and a conversion table depending on how the relationship between the measured body impedance value and the metabolic state index is defined. Can be. If a regression analysis including at least a measured body impedance value and a metabolic state index as variables is used as a method of obtaining the conversion equation, highly reliable metabolic state estimation can be performed.
In the regression analysis, in addition to these variables, height, weight, age, gender, and the like can be considered as variables.
Such a conversion equation may be calculated in the apparatus using measured values or other data, or may be obtained in advance.

According to a third aspect of the present invention, in the second aspect, there is provided a conversion formula calculating means for calculating the conversion formula, wherein the conversion formula calculating means calculates the body impedance measurement value and the metabolic state at two time points. The conversion formula is calculated by linear regression processing based on an index.

If the conversion formula calculating means is provided and the conversion formula is calculated by the linear regression processing based on the measured body impedance value and the metabolic state index at two time points, the calculation processing is simplified. Therefore, the processing can be speeded up and the size of the device such as the storage unit can be reduced.

As such two time points, it is desirable to adopt a time point at which the metabolic state is significantly different. For example, 2
One of the time points, just before breakfast just after getting up,
It can be the time immediately after bathing. This is because the energy metabolism is estimated to be the lowest in the day at the time immediately before getting up and before breakfast, and the energy metabolism is estimated to be the highest in the day immediately after bathing. Also, the metabolic state varies greatly depending on the diet and bathing,
The two time points may be before and after a meal or after an appropriate time after a meal, or before and after bathing.

As the metabolic state index at the two time points, an index obtained by another measurement method or the like can be used, and information for specifying physical characteristics such as height, weight, age, and gender of the subject can be used. It may be obtained from (body-specific information) using a predetermined standard value.

In a fourth aspect based on the third aspect, the apparatus further comprises time information acquiring means for acquiring time information for specifying the time of measurement of the body impedance, based on the time information acquired by the time information acquiring means. The two time points are selected.

The two time points for calculating the conversion formula can be specified by, for example, instructing the subject to a desired time point in an instruction manual or the like, but can be specified by the user inputting the time of measuring the body impedance. The information may be acquired, or, if an impedance measuring unit is provided, the time information may be acquired using a time measuring unit such as a timer at the time of measurement. By providing time information acquiring means for acquiring time information in this way, and selecting two time points based on the acquired time information, a more appropriate time point can be selected, so that a more accurate conversion formula calculation can be performed. Is possible, and the estimation accuracy of the metabolic state index is increased.

In a fifth aspect based on the fourth aspect, the time information is represented by an action of a subject.

When the body impedance measurement time is specified, it can be specified by numerals such as hours and minutes. But,
The metabolic state changes depending on the behavior of the subject's own life, and the daily life pattern is different for each person. A more appropriate choice can be made by expressing by action. In particular, when the user inputs, if the time information is expressed by the subject's actions,
There is no need to check the minutes and the like, and the impedance measurement time can be easily specified and input.

In a sixth aspect based on the first to fifth aspects, the range between the maximum value and the minimum value of the energy metabolism per unit time is divided into a plurality of regions, and the region is converted from the measured body impedance. Which of the plurality of regions is classified as the energy metabolic rate per unit time is used as the metabolic state index.

The metabolic state index may be any index that can indicate the metabolic state, and various indexes can be used. Although the energy metabolism per unit time can be used as a numerical value as a metabolic state index, it is easier for the user to understand if the numerical value is evaluated according to some standard and the evaluation result is used as an index. As such a criterion, a plurality of regions are set by dividing the region between the maximum value and the minimum value, and to which region the energy metabolism per unit time converted from the body impedance measurement value belongs. Classification can be performed. By using the metabolic state index as to which of the plurality of regions the energy metabolism per unit time belongs to as described above, the user can determine the metabolic amount per unit time through which region or stage in the change range. The state can be easily understood. The maximum value and the minimum value used here do not necessarily have to be strictly maximum and minimum, as long as an area can be set to indicate in which part of the change range the energy metabolism per unit time is. Good.

The maximum value and the minimum value of the energy metabolism per unit time may be calculated from standard values obtained by statistics or the like based on body-specific information such as height and weight.
A value obtained from a standard value may be used as an initial value, and this may be updated with a measured value. In addition, since the change pattern of the energy metabolism per unit time in life can be almost estimated by the life pattern, when acquiring the time of impedance measurement by the time information acquisition means, refer to the acquired time information. A maximum value and a minimum value may be set. The maximum and minimum values are
Calculating at least one day is enough to monitor daily health.

The setting of a region (stage) for indicating in which region or stage in the change range the energy metabolism per unit time is not limited to the division of the region between the maximum value and the minimum value. For example, each area can be set based on a standard value. In such a case, if the upper limit of the region on the maximum value side and the lower limit of the region on the minimum value side are not set, the change range can be divided into a plurality of regions without obtaining the maximum value and the minimum value.

In a seventh aspect based on the first to sixth aspects, the guideline information includes information on body fat.

The body impedance is measured by using a predetermined conversion theoretical formula, a conversion table, or the like to calculate the body impedance from the measured body impedance value or the body specification information such as height, weight, age, and gender. Information about body fat, such as fat percentage, body fat mass, lean mass, and obesity degree can be calculated. By performing such arithmetic processing by the conversion means, information on body fat can be provided together with the metabolic state index. That is, it is possible to provide a health management guideline advice device capable of providing more functions and various information.

According to an eighth aspect of the present invention, in the first to seventh aspects, a display means for displaying information including at least the pointer information is provided.

If a display means for displaying information including at least guideline information is provided, the user can easily obtain such information. If information on the operation is displayed on the display means, the user can easily perform the operation.

Along with the display means or separately from the display means, an output means for recording and outputting information such as guide information on a recording medium such as paper may be provided, or may be output to an external device such as a computer or a printer. You may do so.

In a ninth aspect based on the eighth aspect, a display control means for graphically displaying the information is provided.

By providing the display control means for displaying information graphically and displaying various information graphically, information such as pointer information can be provided in a format that is easy for the user to understand.

[0033] In the tenth invention, the first to ninth inventions are characterized by comprising impedance measuring means for measuring the body impedance.

With the provision of the impedance measuring means, the measurement of the body impedance and the provision of the guide information can be performed by one apparatus. That is, it is possible to save trouble such as inputting a value measured by another impedance measuring device, and to obtain useful guide information more easily.

Before describing the measurement procedure by the apparatus 1, the principle of estimating the energy metabolism based on the measured impedance will be briefly described.

Even if the measurement is performed under the same conditions, the measured value of the impedance changes within one day. Such circadian changes are considered to be largely caused by changes in dilatation and contraction of peripheral blood vessels. Although the change in the expansion and contraction of the peripheral blood vessels is proportional to the change in blood flow, a causal relationship is established between the change in blood flow and the change in oxygen supply and heat dissipation that promote metabolism. Therefore, it is considered that the energy metabolism can be estimated by measuring the impedance. However, between these changes, it is considered that the relationship of (1 / impedance change) ∝dilation change of peripheral blood vessels∝blood flow change∝energy metabolism change is established. The estimation formula (conversion formula) is defined as M (kcal / h) = a / Z + b. Here, M: energy metabolism per unit time (kcal / h) Z: bioelectrical impedance (Ω) a, b: constants

However, the equation for estimating the energy metabolism based on the measured impedance value is not limited to the one described above.

Further, the energy metabolism at the time of measuring two different impedances is measured by using the above-described estimation formula or the like or another method, and these measurement results are subjected to a linear regression process. May be used to estimate the energy metabolism. It is desirable that the two time points be time points at which the energy metabolism state is significantly different. For example, one of the two time points may be the time point before breakfast, shortly after getting up in the morning, when energy metabolism is estimated to be the lowest in the day, or the energy metabolism is the highest in the day. It can be immediately after the estimated bathing. Further, the two time points may be set before and after a meal or after an appropriate time of a meal. Further, the two time points may be before and after bathing.

The measurement procedure by the present apparatus 1 will be described with reference to the flowchart shown in FIG.

First, when the power switch is turned on, RA
Measurement preparation processing such as initialization of M and the like and checking of each circuit element and display element is performed (step (S) 1).

Next, body-specific information including height, weight, age, and gender is input through the input mode setting switches 11 to 14 and the numeric keypad 16 (step 2). The input is, for example, when inputting the height, after pressing the height input mode setting switch 11 to set the height input mode,
The height value is input using the keys of the numeric keypad 16 and the enter switch is pressed to confirm the input value. Here, the weight may be represented by the measured value after defecation and urination before breakfast, rather than by measuring and inputting the measured value at each event timing of the day.

Next, an event condition is selected and input (step 3). The event condition expresses the measurement condition using an event in the subject's daily life. For example, before breakfast, before lunch, before dinner, before bathing, immediately after bathing, etc. can be set as event conditions.
It is not limited to these.

The selection and input of the event condition is such that the event name corresponding to the number is displayed on the display unit 9, and the subject selects an event from the event name and inputs the corresponding number using the numeric keypad 16. What should I do? A switch for directly inputting an event such as "before breakfast" may be provided.

It is determined whether or not all the body specific information has been input by "READY?" (Step 4).

If the determination in Step 4 is No, the flow returns to Step 2 to input the unspecified body specifying information.

If the determination in Step 4 is Yes, the subject is notified by displaying the start of measurement on the display unit 9 (Step 5), and the impedance between the measurement sites is measured (Step 6). ). At this time, the current applying electrodes 18,
The impedance is measured by applying a high-frequency current through 19 and detecting the body resistance potential generated by this current through the voltage measurement electrodes 20 and 21.

When the measurement is completed, the subject is notified to the subject by displaying it on the display unit 9 (step 7).

Next, it is determined whether the event condition selected and input in step 3 is before breakfast (step 8).

If the determination in Step 8 is Yes, the lowest metabolic amount M _min is calculated based on the arithmetic expression M _min = a / Z _max + b, with the measured impedance value as Z _max (Step 9).

Next, using the M _min calculated in step 9, the process of updating the stored value in the memory area for storing the value of M _min is performed (step 10). At this time, if the value stored in the memory area is the default value, the current calculated value is stored. If the default value is not stored, the average value of the stored value and the current calculated value is stored as the updated value. .

If No in step 8, it is determined in step 3 whether the selected and input event condition is immediately after bathing (step 11).

If it is determined to be Yes in step 11, the highest metabolic amount M _max is calculated based on the arithmetic expression M _max = a / Z _min + b with the measured impedance value as Z _min (step 12). M _max calculated in 12
_Is used to update the stored value in the memory area for storing the value of Mmax (step 13). The processing for updating the memory area here is performed in the same manner as in step 10.

If the determination in Step 11 is No, the process proceeds to Step 16.

When the process of updating the memory area stored value of M _min or M _{max in} step 10 or step 13 is completed,
The values stored in the memory area of M _min and M _max are read (step 14).

Next, for displaying the metabolic change span,
A classification process is performed (step 15). For example,
_{(M max -M min) / 5} = ΔM Distant, calculated value M _X of metabolic rate is classified into "minimal metabolism" if _{M min ≦ M X <M min} + ΔM, M min + ΔM ≦ M X <M _{If min} + 2ΔM, it is classified as “slightly small metabolism”, and M _min + 2ΔM ≦ M _X
If <M _min + 3ΔM, classify as “standard metabolism”
If _{min + 3ΔM ≦ M X <M} min + 4ΔM classified as "slightly larger metabolism", it is classified as "maximum metabolism" if _{M min + 4ΔM ≦ M X ≦} M max. However, the classification process is M
_It suffices to divide between _max and M _min, and the invention is not limited to the case of dividing into five stages.

Next, the metabolic rate is calculated from the impedance value measured in step 5 by the arithmetic expression M _x = a / Z _x + b (step 16).

Next, metabolism M _X determines belongs to which segment in the 5 Groups of metabolic changes span above (step 17).

Next, a bar graph of the classification of the judgment result is displayed (step 18). For example, as shown in FIG. 4, the area of the corresponding section of the bar graph may be turned on to indicate to which section the bar graph belongs.

Next, based on the body-specific information input in step 2 and the impedance measured in step 6, arithmetic processing is performed using a predetermined conversion formula, a conversion table, and the like, and the body fat percentage, lean mass, While calculating guideline information useful for health management such as body fat mass, obesity level, and muscle mass,
A message is displayed on the display unit 9 (step 19), and the process ends.

By calculating the amount of metabolism at the time of measurement, the metabolic state can be monitored. Monitoring at different times during the day to monitor changes in metabolic status can help you to be aware of your lifestyle. Also, monitor your metabolic status,
Trying to improve your metabolism in your daily life can help improve your lifestyle.

In the present embodiment, the metabolic range at the time of measurement is divided into a plurality of categories, with the time before breakfast being the time of lowest metabolism and the time immediately after bathing being the time of highest metabolism. Although displayed, the guide information that can be provided based on the metabolic rate is not limited to these. Changes in metabolic rate between events may be displayed. Eating a meal improves metabolism for digestion and absorption, so displaying metabolic changes before and after a meal indicates whether digestion and absorption are good, and whether a proper diet necessary for the activity is made. It can be used as monitor information. If metabolic changes before and after bathing are displayed, it is possible to confirm the presence or absence of metabolic decline due to poor blood circulation or the like based on the magnitude of the change. By displaying the metabolic change after waking up, it becomes possible to monitor the physical condition such as lack of concentration due to hypothermia or the like. If the exercise is inappropriate, the metabolism does not change properly. Therefore, if the metabolic changes during and before and after exercise are displayed, it can be used for confirming energy metabolism due to exercise and grasping the appropriate amount of exercise.
