[0002]

2. Description of the Related Art Conventionally, various methods such as an underwater body weight method, a caliper method, and a heavy water dilution method have been adopted as means for determining a body fat percentage. Among them, the impedance method of measuring the impedance value of a living body by passing a minute current through the living body and calculating the body fat percentage from the value is often adopted. This impedance method enables simple measurement, and various devices are provided from business use to home use. As an example, one that measures with the wrist is commercially available. There are two types: a type in which a conductive paste is applied to the clip-shaped electrode, and a type in which the conductive paste is applied to the wrist with a conductive gel. It has the function of reducing the effect as an error.

An arithmetic unit for calculating a body fat percentage or the like from an impedance value or input personal physique data; and a display unit 4 for displaying the input personal data or the calculated body fat percentage. A positioning portion 6 having a three-dimensional shape for adjusting the position of the lower arm 8 of the user is provided around the electrode 5 to be taken out. 8, the body fat percentage can be easily measured, and the positioning portion 6 can be used to accurately apply the electrode 5 to a fixed position of the lower arm 8, so that the measurement accuracy can be easily increased. That.

It is preferable that the positioning portion 6 having a three-dimensional shape for adjusting the position of the lower arm 8 of the user is formed of a recess 6a. Can be accurately and easily adjusted to the electrode 5.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below. The body fat meter A includes impedance measuring units 2 and 2 for measuring a biological partial impedance, an input unit 3 for inputting required personal physique data, and a storage unit for storing personal data input in the past (FIG. (Not shown), a calculating unit (not shown) for calculating a body fat percentage and the like from the measured impedance value and the input personal physique data, and the input personal data and the calculated body fat percentage are displayed. A main body is constituted by the display unit 4. In the present embodiment, FIG.
As shown in FIG. 1, the device main body 1 and the impedance measuring units 2 and 2 are provided integrally, and the input unit 3 and the display unit 4 are provided on the panel surface 1a of the device main body 1, A pair of electrodes 5 for extracting biological information as an electric signal is provided on the electrode surface 2a of the impedance measuring unit 2. The pair of electrodes 5 are arranged along the direction in which the lower arm 8 of the user is extended. The number of the electrodes 5 may be one or three or more. Although the impedance measuring units 2 and 2 are provided integrally with the device main unit 1, they may be formed separately. In this case, the impedance measuring units 2 and 2 can be used separately from the device main unit 1. Becomes

Here, the panel surface 1a and the electrode surface 2a
Are inclined at a predetermined angle with respect to the horizontal plane. The inclination direction is the lower arm 8 when the lower arm 8 of the user is extended.
Approximately coincides with the inclination direction. The left and right impedance measuring units 2 are arranged at a distance substantially equal to the shoulder width of the user, so that the user can easily bring the lower arm 8 into close contact with the electrode 5 with the elbow extended. It is.

A positioning portion 6 having a three-dimensional shape for adjusting the position of the lower arm 8 is provided around the electrode 5. In the present embodiment, the positioning unit 6 includes the left and right bases 7.
Are formed at the distal end portions of each of them, and are constituted by concave concave portions 6a to which a user's wrist 9 can be applied. Then, as shown in FIG. 2, the user sits on the chair 10 and
In the case where measurement is performed by the body fat meter A installed above 1, personal data such as weight, height, age, and gender are input from the input unit 3 in preparation for measurement. This data content is displayed on the display unit 4 as needed. This personal data is stored in the storage unit as needed.

When the measurement button is pressed after the preparation for measurement is completed, a standby mode is set. In this state, when the user places the lower arm 8 on the electrode surface 2a of the impedance measuring unit 2, the measurement starts after a certain period of time. At this time, since the electrode surface 2a of the impedance measuring unit 2 is not horizontal but inclined, the user can make the lower arm 8 adhere to each electrode 5 with the elbow extended. Also, at this time, by applying the wrist 9 to the recess 6a provided at the tip of the electrode surface 2a, the plurality of electrodes 5 can be accurately and easily applied to the fixed position of the lower arm 8. In addition, since the panel surface 1a of the apparatus main body 1 is also inclined, the operation at the time of data input by the input unit 3 becomes easy, and the measurement operation can be performed in a comfortable posture. Although the lower arm 8 is applied to the electrode surface 2a, it goes without saying that the measurement may be performed with the wrist 9 applied.

Thereafter, when the measurement is completed, the calculation unit calculates the body fat percentage, the body fat mass, the body mass index, etc. of the user from the measured impedance value and the input or called personal data, and the display unit 4 Is displayed with. At this time,
The body fat percentage, body fat mass, and body mass index measured in the past are called up together with personal data as necessary, and displayed on the display unit 4.

As described above, the body fat percentage and the like can be easily measured only by placing the lower arm 8 on the electrode surface 2a of the impedance measuring section 2. Therefore, it is necessary to use a gel or paste for wrist measurement as in the conventional case. And is very easy for the user to use. In addition, since the electrode 5 can be accurately and easily applied to the fixed position of the lower arm 8 by the recess 6a serving as the positioning portion 6, the position at which the electrode 5 is applied to the lower arm 8 varies, and the measured value changes. The problem of getting lost is also eliminated. In addition, since the electrode surface 2a is not horizontal but is inclined, it is easy to bring the electrode 5 into close contact with the lower arm 8, and as a result, the measurement accuracy can be easily improved with the simple structure of providing the recess 6a. There is an advantage that it can be increased.

FIG. 3 shows another embodiment of the present invention. The basic structure of the body fat scale A is the same as that of the embodiment of FIG. In this embodiment, the entire panel surface 1a and the electrode surface 2a are not inclined, and the electrode surface 2a is provided with a projection 6b on a portion where the palm of the base 7 contacts when the lower arm 8 is applied to the electrode 5. Is provided. The projection 6b is formed, for example, in a semicircular cross section, and the electrode 5 can be accurately and easily applied to a predetermined position of the lower arm 8 by the user gripping the projection 6b with the palm. Therefore, similarly to the above-described embodiment, the measurement accuracy can be improved, and the measurement can be performed more easily than the conventional measurement using a gel, a paste, or the like. Further, the panel surface 1a of the apparatus body 1
There is also an advantage that the display unit 4 is easy to see and the display contents are easy to confirm by making the state of no inclination. still,
The display unit 4 and the impedance measuring unit 2 are provided integrally, but may be configured separately, as in the above-described embodiment.
