Abstract: To provide a device determining edema of a human body on the basis of a biological impedance method, and an operation method.SOLUTION: Steps of an operation method of a device which determines edema of a human body on the basis of a biological impedance method are as follows. First, stimulation current is generated, and the stimulation current is flown to a measurement part of a measuring object in different measurement modes. Then, impedance value Z corresponding to the current measurement mode is obtained. Next, on the basis of the obtained impedance value Z, height, age, weight and sex of the measuring object, an edema index is calculated. As stated above, the current invention reflects edema situations on the basis of the obtained impedance value Z of the measuring object, height, age, weight and sex of the measuring object. The edema determination is closely related to the above-mentioned parameter. Therefore, according to technical features of the current invention, the measuring object can obtain edema determination situations of the measuring object alone in 11 kinds of different measurement modes. On the other hand, data detected by the current invention has operational convenience since the edema situations of the measuring object can be reflected accurately.SELECTED DRAWING: Figure 1
