Hereinafter, the constitution of each part of the present invention will be described in detail.

First, the main body 10 can be raised by a person, and a control unit 60, a power supply unit 80, various sensors, and the like are built therein.

On the front side of the platform 12, a display unit 70 for displaying a user's body fat percentage, normal blood glucose and blood pressure, and weight is provided. Of course, the side surface or the upper surface of the main body 10 is provided with an operation switch 90 which can control the supply of the power of the power supply unit 80 to the control unit 6.

The body 10 is provided with a body weight measuring unit 20 capable of measuring the weight of the user when the user is standing on the platform 12. At this time, the body weight measuring unit 20 may include various sensing means such as a load cell, a strain gage, and the like in a known configuration.

On the other hand, the platform 12 is provided with a body fat measurement unit 30 for measuring the body fat of the user, a bloodless blood glucose measurement unit 40 for measuring the blood glucose of the user by the bloodless measurement system, (50) is provided. Accordingly, when the user is placed on the platform 12 of the scale, he / she can automatically check the user's body fat, blood sugar and blood pressure without any special operation.

In this case, the body fat measurement unit 30 may be constituted by electrodes for measuring the difference in voltage between the right foot and the left foot, for example, in the right foot, and in this case, the difference in voltage means the body resistance Body fat can be calculated by calculating body resistance.

In this case, body fat percentage is calculated by dividing body fat by body weight and multiplying by 100. Normally, it is considered to be within the normal range if 10-20% for male and 18-28% for female. However, in the present invention, it can be judged as normal if the body fat percentage is within the setting range of 10 ~ 28% and 18 ~ 20% without discrimination between men and women. In this case, the body weight used in the calculation of the body fat percentage utilizes the user's body weight data measured through the body weight measuring unit 20.

The bloodless blood glucose measuring unit 40 uses a non-blood-collecting blood glucose sensor that does not involve blood sampling. In this case, for example, a CGMS using Raman spectroscopy, an optical glucose sensor using near- Glucose Sensor, PGS), and the like can be applied.

Normally, blood glucose testing can be used to diagnose diabetes, to manage diabetes, and to evaluate metabolic syndrome. There are several blood tests to measure glucose levels in the blood, such as random blood glucose test, fasting glucose test, glucose test, and hemoglobin A1C test. At this time, randomized blood glucose testing can be performed at any time, regardless of diet. High blood glucose levels above 200 mg / dL (11.1 mmol / L) or diabetes mellitus with hyperglycemia suggest diabetes. The fasting blood glucose test is performed without food or drink for at least 8 to 12 hours. It is usually measured after sleeping overnight. The fasting blood glucose level is not more than 100 mg / dL (5.55 mmol / L) And fasting blood glucose levels above 126 mg / dL (7.0 mmol / L) suggest diabetes.

Therefore, in the present invention, it is assumed that blood glucose is measured irrespective of whether or not a meal is taken, and it can be determined that blood glucose is normal when the blood sugar measured by the blood-sugar-free blood glucose measurement unit 40 is 200 mg / dL (11.1 mmol / L) .

The blood pressure measuring unit 40 may be configured to measure blood pressure of a user and may include various types of blood pressure sensors used for measuring blood pressure information from a living body. In this case, it is possible to use a sensor part which is a pressure-electric conversion part such as an electrocardiograph or a catheter tip blood pressure meter used in an open blood pressure measurement method.

Blood pressure means the pressure of the blood acting on the inner wall of the artery. Blood pressure can be defined through two measurements. Systolic blood pressure refers to the arterial blood pressure when the heart contracts, and diastolic blood pressure refers to the arterial blood pressure when the heart is relaxed between heart beats. More specifically, systolic blood pressure is a pressure applied to the blood vessels when the heart contracts, which is used to diagnose hypertension. When the systolic blood pressure is higher than 140 mmHg, hypertension is suspected when the blood pressure is higher than 120 mmHg. Diastolic blood pressure is a pressure applied to the blood vessel when the heart relaxes. It is used for the diagnosis of hypertension. If diastolic blood pressure is above 90 mmHg, hypertension is suspected.

In the present invention, since the systolic blood pressure and the diastolic blood pressure can not be measured separately, it can be determined that the blood pressure is within the normal range when the blood pressure measured by the blood pressure measuring unit 50 is less than the setting range of 140 mmHg.

The control unit 60 includes a microcomputer having a built-in memory and stores a driving program. The control unit 60 includes a body weight measuring unit 30, a blood-less blood glucose measuring unit 40, (Body weight, body fat, blood glucose, blood pressure) of the blood glucose meter 50. Of course, the present invention may also include a memory separately from the controller 60 to store the driving program and data.

When the user turns on the platform 12, the control unit 60 receives the weight data from the weight measuring unit 20 and collects the weight data Blood glucose and blood pressure data measured by the body fat measurement unit 30, the blood-sugar-free blood glucose measurement unit 40 and the blood pressure measurement unit 50 are collected and calculated as a numerical value, and the body fat and body weight are calculated And whether or not the blood glucose and blood pressure are within the normal range.

The display unit 70 may be configured in various forms such as an LCD or a 7-segment LED to display the weight of the user. Of course, the display unit 70 also displays the percentage of body fat, and whether the blood glucose and blood pressure are normal.

In addition, the power supply unit 80 may be a removable battery in the main body 10, and the power supply unit 80 may be provided with a household power source by converting it into an adapter or a rechargeable battery.

The main body 10 further includes a sound output unit 72 whose sound output is controlled by the control unit 70 so that the body fat measurement unit 30 and the bloodless blood glucose measurement unit 40 in the control unit 70, And the user's body fat, blood sugar and blood pressure measured by the blood pressure measuring unit 50 to determine whether the body fat percentage, the blood glucose level, and the blood pressure are normal or not. In this case, the sound output unit 72 may be constituted by a speaker and output a normal state of the item (the body fat percentage, the blood sugar and the narrowing pressure), but it may be constituted by a buzzer so that any one of the items It is also possible to configure to output a warning sound in case of an abnormal condition.

The main body 10 is provided with a wireless transmission unit 74 and transmits health information including the body fat percentage, normal blood glucose and blood pressure as well as the weight of the user to the smart phone 100 of the user. In this case, the data communication with the user's smartphone 100 can be performed through Bluetooth or NFC communication. In this case, the distance to the main body 10 can be adjusted according to the Bluetooth or NFC communication mode.

Of course, it is preferable that a healthcare application 110 for storing the health information of the scale 1 and managing the trend of the scale 1 is installed in the smartphone. In this case, it is preferable that the healthcare application 110 is downloaded from a remote server (not shown) operated by the manufacture or distribution manager of the scales 1.

Hereinafter, an operation example of the digital scales according to the present invention will be described with reference to FIG. 1 to FIG.

The power supply of the power supply unit 80 is supplied to the controller 70 and initialized when the driving switch 90 provided in the main body 10 is turned on for use of the digital scales 1 according to the present invention.

The control unit 70 collects the body weight data from the body weight measuring unit 20 and at the same time the body fat measurement unit 30 and the bloodless blood glucose measurement unit 40 and the blood pressure measurement unit 50 Blood glucose and blood pressure data of the user measured in the blood glucose meter and the blood glucose level and the blood glucose level and the blood glucose and blood pressure are within the normal range.

At this time, when the socks or the like are brought on the platform 12, it is impossible to measure the body fat and blood sugar through the body fat measurement unit 30 and the bloodless blood glucose measurement unit 40, and as the error in blood pressure measurement increases, 12) to measure health information.

When the user is placed on the platform 12, the controller 60 outputs the body fat percentage, blood glucose and blood pressure as well as the body weight to the display unit 70.

In this case, the controller 70 divides the body fat mass measured by the body fat measurer 30 into body weights, multiplies the body mass by 100, calculates the body fat percentage, compares the body fat mass to determine whether it is within a set range of 18 to 20% It is determined whether or not the blood glucose measured by the blood pressure measuring unit 40 is less than or equal to the set value of 200 mg / dL (11.1 mmol / L), and whether the blood pressure measured by the blood pressure measuring unit 40 is less than 140 mmHg .

Accordingly, the controller 60 displays 'normal' on the display unit 70 when the body fat percentage, blood glucose and blood pressure are normal, and displays 'abnormal' on the display unit 70 when the body fat percentage, blood glucose and blood pressure are out of the normal range.

The control unit 70 outputs to the voice output unit 72 whether the body fat percentage, the blood glucose level, and the blood pressure are normal, so that the user can perceive the auditory perception.

In addition, the control unit 70 transmits health information of the user who measures the body weight to the smartphone 100 of the user whose health management app 110 is activated through the wireless transmission unit 74, So that it can be managed.
