[Problems to be solved by the invention]
However, the above-described related art has the following problems.
The cycle machine has a fixed measurement location, and cannot measure calorie expenditure when a subject walks or runs away from it.
Even with the same step count of 1000 steps, the step-counter consumes different calories depending on whether the subject is running or walking, and cannot measure the quality of the exercise.
Further, the device described in Patent Literature 1 displays the cardiac output of the subject, but cannot distinguish between a case where the heart rate increases due to tension and a case where the user exercises.
Further, in the devices using the acceleration sensors described in Patent Documents 2 and 3, the cause of the acceleration cannot be distinguished between the case of the acceleration of the movement by the vehicle and the case of the acceleration by the movement of the person, and the exercise is substantially performed as the calorie consumption. This includes the problem of not being able to measure the net calorie consumption, because it also includes acceleration of traveling by car, train, or bus.

[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a diagram showing one embodiment of a calorie consumption meter of the present invention. The calorie consumption meter includes a heart rate meter 1 for detecting the heart rate of the subject, a sphygmomanometer 2 for detecting the blood pressure of the subject, an acceleration sensor 3 for detecting the movement of the subject, and an operation for calculating the measurement results. A control unit 6 including a unit 5 and a display unit 10 for displaying measurement results and calculation results are provided as main components.
[0008]
As the heart rate meter 1, for example, a device that can measure a heart rate based on an electrocardiogram waveform can be used. In a preferred embodiment of the present invention, the heart rate meter 1 is preferably a wristwatch type having a wristband to be used by being worn on the wrist of the subject, especially the wrist. When the main body of the measurement meter including the acceleration sensor 3, the input unit 4, the control unit 6, and the display unit 10 is attached to the waist or abdomen of the subject, the heart rate meter 1 attached to the wrist unit is separate from the main body of the measurement meter. It is desirable to be configured to operate with a power supply (battery) and transmit the measurement data to the main body of the measurement meter wirelessly or by wire.
[0009]
The sphygmomanometer 2 can use a device that measures the blood pressure of the subject by a method such as an oscillometric method or a minute pressure sensing using a semiconductor pressure sensor. In a preferred embodiment of the present invention, the sphygmomanometer 2 is preferably a sphygmomanometer using minute pressure sensing that can easily measure the blood pressure at the subject's arm, particularly at the wrist. When measuring blood pressure at the wrist unit, the sphygmomanometer 2 is attached to the same wristband as the heart rate meter 1 and is operated with the same power supply, and furthermore, it is configured so that measurement data can be transmitted to the main body of the measurement meter in the same manner. Is preferred.
[0010]
In the acceleration sensor 3, the acceleration sensor senses the level (exercise intensity) at which the subject moves, detects the intensity of acceleration in a plurality of stages, for example, in five or ten stages, and accumulates the results to calculate the amount of exercise, the number of steps, It is preferable to use a device that can determine the calorie consumption. As the sensor section of the acceleration sensor 3, a conventionally known small acceleration sensor (for example, a capacitance type acceleration sensor or the like) can be used. In a preferred embodiment of the present invention, the acceleration sensor 3 is preferably of a type that can be worn on the waist or abdomen of a subject, particularly on a belt. The acceleration sensor 3 can be provided integrally with a main body of the measuring meter including the input unit 4, the control unit 6, the display unit 10, and the power supply 11, and can be wirelessly connected to the main body of the measuring meter provided separately from the body of the subject. Alternatively, it may be configured to be able to transmit by wire.
[0011]
The input unit 4 is provided with a plurality of input keys for inputting personal information (parameters) of the subject, storing the personal information in the RAM 8 of the control unit 6, and changing / correcting the personal information as necessary. I have. The personal information of the subject includes, for example, gender, age, weight, height, daily exercise amount of the subject, and the like. The configuration of the input key is not particularly limited, and the input key may be input in a format corresponding to the question item stored in the ROM 7 or may be input by a touch panel method.
[0012]
The control unit 6 includes a calculation unit 5, a ROM 7, a RAM 8, and a signal processing unit 9. Further, the control unit 6 includes a clock function for displaying time. The control unit 6 is connected to a power supply 11 for operating the main body of the measurement meter, and a display unit 10. The control unit 6 stores the above-mentioned personal information input from the input unit 4 in the RAM 8 through the signal processing unit 6 with the power supply 11 turned on, and stores the heart rate meter 1, the sphygmomanometer 2 and the acceleration sensor 3 The arithmetic unit 5 calculates a necessary display signal based on a program stored in the ROM 7 from the signals input from the CPU and received through the signal processing unit 6 and the personal information. The signal calculated by the calculation unit 5 is output to the display unit, and various information is displayed.
[0013]
As the power supply 11, various batteries such as a dry battery, a button-type battery, a secondary battery, and a solar battery are preferably used, and a long-life dry battery, a lithium battery (button type), and the like are preferably used.
[0014]
As the display unit 10, a thin flat display panel capable of displaying with low power is used, and for example, a liquid crystal display panel, an EL display panel, or the like is suitably used. In addition, as described above, the display unit 10 may be a touch panel and have the function of the input unit 4.
[0015]
To use the calorie consumption meter configured as described above, the power supply 11 of the main body of the measurement meter including the acceleration sensor 3, the input unit 4, the control unit 6, the display unit 10, and the power supply 11 is turned on, and the use is started. In doing so, personal information (parameters) of the subject is input from the input unit 4 as necessary. These pieces of personal information include gender, age, height, weight, and the like, and are stored in the RAM 8.
[0016]
The main body of the measuring instrument to which the personal information has been input is worn on a belt on the abdomen of the subject. A wristband having a heart rate meter 1 and a sphygmomanometer 2 is attached to the wrist of the subject. From the heart rate meter 1 and the sphygmomanometer 2 of the wristband, each measurement data is transmitted to the signal processing unit 9 of the main body of the measurement meter by wireless or wire. In this way, the subject attaches the measurement meter body to the belt and attaches the wristband having the heart rate meter 1 and the sphygmomanometer 2 to the wrist portion, and conducts daily life including exercise. The movement of the subject is sensed by the acceleration sensor 3 as an acceleration level, and a signal of the acceleration level is sent to the arithmetic unit 5 through the signal processing unit 9.
[0017]
The total calorie consumption of the subject is calculated from the following equation by accumulating the acceleration level per time sensed by the acceleration sensor 3 and converting it into calorie consumption (amount of exercise).
Total calorie consumption = basal metabolism + exercise Here, the basal metabolism is calculated according to a program stored in the ROM 7 based on personal information such as height and weight, and stored in the RAM 8.
[0018]
However, the total calorie consumption calculated in this manner does not consider the quality of exercise. For example, when the subject moves on a vehicle, the acceleration sensor 3 detects the acceleration even if the subject does not exercise. However, since this acceleration is added to the amount of exercise, it cannot be said to be a net calorie consumption.
In order to overcome this drawback, the present invention measures the heart rate and blood pressure of the subject simultaneously with the measurement of the acceleration level, estimates the quality of exercise from these measurement data, and measures the net calorie consumption. I made it.
[0019]
The subject's net calorie consumption corresponds to the total amount of the basal metabolic rate and the calories consumed by the subject's actual exercise (net exercise calories consumed).
In the present invention, in order to estimate the quality of the exercise of the subject, based on the acceleration, heart rate, and blood pressure data measured by the acceleration sensor 3, the heart rate meter 1, and the sphygmomanometer 2 in the control unit 6, the following ( 1) to (3) estimation and classification.
(1) When the acceleration is high, the heart rate is higher than at rest, and the blood pressure is higher than at rest, the subject exercises more;
(2) movement by a vehicle when acceleration is high, heart rate is at rest level, and blood pressure is at rest level;
(3) When the acceleration is low, the heart rate is higher than at rest, and the blood pressure is slightly higher than at rest, this is due to the tension of the subject.
[0020]
In the above (1) to (3), the subject actually exercises only in the pattern (1), and (2) and (3) show that the calories consumed by the subject increase from the basal metabolic rate. It is estimated that there is little to do. Therefore, it can be said that the net exercise calorie consumption is close to the amount represented by (1). Therefore, in the present invention, the total amount of the subject's basal metabolism and the calorie consumption in (1) is determined to be the net calorie consumption and can be displayed on the display unit 10. In addition to displaying the total calorie consumption and the net calorie consumption, the calorie corresponding to the above (2) and / or (3) can also be displayed.
[0021]
The display unit 10 can display various data such as heart rate, blood pressure, acceleration level, number of steps, time, cumulative exercise amount, and cumulative calorie consumption, in addition to the calorie consumption.
It is also possible to provide an audio output such as a speaker on the display unit, display the data on the display unit 10, output the data by audio, and output the advice, warning, time, etc. stored in the ROM 7 by audio. it can.
Further, in a hospital or the like, the data stored in the control unit 6 can be transmitted to a personal computer or the like wirelessly (including infrared communication and a mobile phone) or by wire to collectively monitor data of a plurality of subjects.
[0022]
