Abstract
Disclosed is an edema measuring method comprising the steps of: putting at least two pairs of electrodes on different locations selected in the body; making an alternating current to flow in the body via one pair of electrodes; measuring voltage appearing between the other pair of electrodes; calculating impedance on the basis of the supplied alternating current and the measured voltage; and calculating an index value representing the degree of edema on the basis of the impedance. Also, an apparatus using the method is disclosed.
Claims19
A method for measuring the degree of edema of a person characterized in that it comprises the steps of:
- putting at least two pairs of electrodes on different locations selected in the body of the person;
- supplying alternating current to one pair of electrodes;
- measuring voltage appearing between the other pair of electrodes;
- calculating impedance on the basis of the supplied alternating current and the measured voltage;
- and
- calculating an index value representing the degree of edema on the basis of the impedance.
An apparatus which is capable of measuring the degree of edema of a person characterized in that it comprises:
- at least two pairs of electrodes to be put on selected locations in the body of the person;
- an alternating current supplying device which supplies alternating current to one pair of electrodes;
- a voltage measuring device which measures the voltage appearing between the other pair of electrodes;
- and
- an arithmetic unit which calculates impedance on the basis of the supplied alternating current and the determined voltage, and calculates an index value representing the degree of edema on the basis of the so calculated impedance.
