Method and device for measuring bio-impedance data of a person
A method and a device for determining biological impedance data of a person, in which least one impedance value is measured with the use of at least two electrodes and is transmitted to an evaluation unit. In the area of at least one output device, information concerning the person is made available for assuming an optimum body posture for the measurement of the biological impedance.
1. A device for determining biological impedance data of a standing person, the device comprising: two pairs of electrodes for each hand of the standing person for measuring at least one biological impedance value, wherein each of the two pairs of electrodes for each hand is arranged on a separate base element and the base elements are arranged on a support element so that the base elements are separated by a distance, the base elements being arranged symmetrically relative to a vertical mid-line of the support element, and each electrode is dimensioned to be contactable with two fingers of the person; at least two electrodes for each foot of the standing person for measuring at least one biological impedance value; an evaluation unit for transmitting measurement values, the electrodes being coupled to the evaluation unit; an output device for making available information concerning an optimum body posture of the person, the evaluation unit being coupled to the output device, wherein the output device is constructed for showing visual information on a display; at least one measuring device for determining an actual body posture of the person, wherein the evaluation unit is operatively constructed to carry out a comparison between a desired value and an actual value with respect to body posture of the person; and, an electronic storage device that stores data identifying the person, data regarding a desired body posture of the person and data regarding electrodes contacted by the person when the person is correctly positioned so that with a renewed use of the device for determining biological impedance data by the person an actual occupied body posture and actual contacted electrodes are identified and the output device directs the person with corresponding indicators to assume positions dictated by the stored data, within a maximum allowable deviation, wherein the display is configured to show corrective information at least for adjustments of a horizontal position of the hands of the person relative to the pairs of electrodes to be used by the person, wherein the device for determining biological impedance data is a body composition analyzer.
2. The device according to claim 1 , wherein the measuring device is a camera.
3. The device according to claim 1 , wherein the measuring device is a mechanical measuring device.
4. The device according to claim 1 , wherein the measuring device is a contactless measuring device.
5. The device according to claim 1 , comprising three pairs of electrodes for each hand of the standing person, each pair of electrodes being arranged on a separate base element.
