Description

[Detailed Description of the Invention] Industrial Application Field The present invention provides a method for applying a voltage value to a living body, when the current value flowing through the "brim" position of the living body is more than a constant times that of other parts other than the "swelling". This relates to a spit detector that detects "spits" in living organisms by utilizing certain facts.

The structure of the conventional example and its problems The principle of the conventional dip detector is as shown in Figure 1.
A constant voltage value is applied to the living body 5 via the meter 2.

However, as shown in the figure, the number of electrodes 4 is two, and the configuration is such that the position of the "brim" is searched based on the magnitude of the amount of current flowing between the electrodes. Adjustments had to be made sequentially for each measurement site using the adjustment volume 3. OBJECTS OF THE INVENTION The present invention eliminates the above-mentioned drawbacks of the prior art, and is intended to correct the above-mentioned drawbacks of the prior art, and to accurately adjust the "spit" without making sequential adjustments at any part of the body.
The position of the object can be detected.

Structure of the Invention The present invention applies three electrodes (one of which is a common electrode) to the skin of a living body, applies a constant voltage between the common electrode and the other two electrodes, and applies a voltage to each electrode. The amount of current that flows is automatically adjusted to a measurable value according to the part, then converted to a voltage value, one of the voltage values is multiplied by a constant, and the value is compared with the other voltage value to make a decision. By configuring this system, it is possible to find the exact position of the "toe" in any part of the body without having to adjust the sensitivity.
