Embodiment Construction

[0015] A typical bioelectrical impedance measurement device includes: a standing platform on which a person to be measured stands with both feet. For each foot, two electrodes are formed on the platform, for example one in the heel area and one in the forefoot area. Furthermore, two grips are provided which are gripped in a specific way by the user, thereby establishing contact with two electrodes of each hand, for example one at the thumb and the other at the palm.

[0016] According to the invention, the control and evaluation unit of the bioelectrical impedance measuring device is arranged to carry out a pre-measurement, during which it is determined which electrode is in electrical contact with the person to be measured. For this purpose, for example two electrodes on different limbs can be selected in succession and a current can be applied to both electrodes (in the premeasurement this current can be alternating or direct current), wherein the current flowing through the...

Abstract

The present invention provides a bioimpedance measuring device which is used for determining compositional data of the human body. The bioimpedance measuring device is provided with the following components: at least eight electrodes for allocating a pair of electrodes for each of the four limbs; a measuring circuit which comprises a current source and a current and voltage measuring circuit that is selectively coupled with the electrodes; and a control and analysis unit which is set for applying current to the two electrodes for confirming the voltage generated by two other electrodes on a different limb and determining the impedance of human body segment based on the current and the voltage according to a plurality of preset measurement plans, wherein the control and analysis unit is further set for applying the current through two electrodes and measuring the current generated by the electrodes which are applied with current and / or the voltage on other electrode in premeasurement. Which electrodes have contact is determined, and a matching measurement plan is selected based on the determined allocation of the electrodes with contact. In the matching measurement plan, only the electrodes are used for the current applying and voltage measuring of the determined allocation of the electrode with contact.

Description

technical field [0001] The invention relates to a device for bioelectrical impedance measurement for determining body composition data of a human body and a corresponding method. Background technique [0002] The electrical conductivity of the human body is strongly influenced by its water content. Since areas of the body that do not contain fat, such as muscles and body fluids, contain the major part of the water content of the body, whereas adipose tissue on the other hand has a relatively low water content, if at least further data such as a person's height and weight are considered, then Determining the electrical conductivity (or determining the reciprocal resistance or impedance of a body or body segment) allows conclusions to be drawn on relative fat content. [0003] A method and device for bioelectrical impedance analysis are described, for example, in WO 97 / 01303. The device described therein comprises eight electrodes, four electrodes for the feet, in each case ...
