Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a body component analyzer with a handle adjustable, and more particularly to a body component analyzer with a handle having three degrees of freedom that can be rotated vertically, horizontally and rotatably.

[0002]

2. Description of the Related Art A body component analyzer is a device for analyzing constituent components of the body by passing a current between the hands and feet of the body and applying a voltage to measure the bioimpedance of each part of the body.

Generally, such a device is based on the principle that the higher the electrical conductivity of the body, that is, the lower the body impedance, the higher the proportion of water and muscle. Recently, the body fat measurement related to obesity, etc. Is interested in doing.

The accuracy of the body composition analyzer as a result of body fat measurement depends directly on the accurate measurement of the impedance of the body, and the posture of the person to be measured is important for the accurate measurement of impedance. affect.

That is, it is important to improve the accuracy of such a device so that the person to be measured can always measure in a fixed posture regardless of the physical conditions such as the height difference of the person to be measured. It is a key.

A conventional body component analyzer will be described with reference to FIG. On the table 130 on which the person to be measured is placed, the foot electrodes 131, 1
32 is provided. Case 1 extending vertically from the base 130
A handle 134 is fixed to both sides of 33, and hand electrodes 135 and 136 are provided on the handle 134.
An analysis device 137 for measuring the impedance of each part of the living body is provided in the case 133, and a display plate 138 for displaying weight, body fat weight, etc. is provided above the case 133.

Each of the electrodes 131, 132, 135, 135 is connected to an analyzer 137, and the electrodes 131, 13
2, 135, 136 are switched by a switch circuit (not shown), an alternating current is passed through the living body, and a voltage is applied to measure the impedance of each part of the living body.

Considering this body component analyzer, the handle 134 held by both hands is shown in FIG.
3, the handle 134 is provided with two electrodes 135 and 136, respectively, so that the electrode 135,
You can hold 136 with both hands.

However, such a shape of the handle affects the impedance value to be measured because the height of grip of the handle changes depending on the height of each person to be measured, which changes the posture of the person to be measured. Become.

Therefore, since the impedance of the person to be measured cannot be accurately measured in the shape of the handle in which the height and width of the handle are constant, the shape of the handle is not so preferable in the body component analysis of the person to be measured. .

FIG. 3 (a) is a view of Patent No. 3292373 (the title of the invention; a human body component analyzer using a new electrode system based on bioelectrical impedance analysis) invented to solve the problem shown in FIG. FIG. 3 is a perspective view of a body component analyzer, which includes a handle 140 with an electrode and an analyzer 13.
7 are connected by a line 142, and the person to be measured is made to take a posture with care while holding the handle 140.

Since the handle 140 having such a configuration can maintain the posture of the person to be measured regardless of the height condition of the person to be measured, regardless of the height of the person to be measured. Since it is constant, the problem of posture change due to the handle of the body component analyzer described with reference to FIG. 4 can be solved, and the impedance of each part of the living body can be measured more accurately.

[0013]

However, in the case of such a handle system, the handle 140 is shown in FIG.
As shown in (b), the hook 140 of the handle 140 is attached to the fastener 143 provided on the side of the case 133.
From the state in which 44 is hooked, the person to be measured must remove the handle 140 as shown in FIG. 3C, and after the measurement is completed, the handle 140 must be hooked on the hook portion 144 again.

Therefore, it is inconvenient for the person to be measured to take the handle 140 and to restore the handle 140 to the original state after the measurement, and there is a problem in that the handle 140 is damaged when dropped. .

Accordingly, the present inventor has solved the problem that the difference in height affects impedance measurement in the body component analyzer of FIG. 4, and at the same time, the handle is simple to use.
It was decided to develop a body composition analyzer with a new adjustable handle that does not have the risk of damage like the body composition analyzer of the above.

An object of the present invention is to provide a body composition analyzer in which the height of the person to be measured does not affect impedance measurement.

Another object of the present invention is to provide a body fat analyzer which is convenient for the handle of a person to be measured.

Still another object of the present invention is to provide a body fat analyzer which is free from the risk of damage caused by dropping the handle.

Still another object of the present invention is to provide a body fat analyzer having a handle that can be rotated up and down, left and right, and rotatable.
