Abstract
A method and a device for determining an estimation value of the body weight of a person, in which at least one measurement value typical for a biological impedance measurement is determined and transmitted to an evaluation unit. The evaluation unit processes the measurement value together with individual or several individual data of the person as well as taking into consideration statistical data concerning other persons, in order to determine an estimated value for the weight of the person.
Claims8
A method for determining an estimation value of body weight of a human person without presently using a scale, comprising the steps of:
- determining with electrodes on both hands and both feet of the body of the human person at least one measurement value for biological impedance measurements;
- transmitting the measurement value of the biological impedance measurement to an evaluation unit;
- processing the measurement value in the evaluation unit together with at least one additional datum of the human person and determining an estimated value for the body weight of the human person, taking into consideration statistical data concerning other human persons, wherein the processing step includes using the measurement value of the biological impedance measurement as well as the statistical data and the additional datum to determine the estimated weight value of the human person, and further includes evaluating a correlation between the measurement value of the biological impedance measurement and the body weight of the human person, wherein measurement values of the biological impedance measurement taken at least at two different points in time are evaluated in the evaluation unit and compared in determining the estimated value for the body weight, wherein one of the points in time is in real time and another of the points in time is an earlier point in time;
- and displaying the estimated value for the body weight, wherein the measurement value is determined using a body impedance analyzer (BIA), wherein actual measurement values of the BIA are impedance values of the body between predetermined measurement points, and wherein the functional dependency of parameters determined by the BIA on the weight of the human person is utilized for resolving a functional relationship according to the weight, wherein the temporal course of the impedance values is evaluated, the method further comprises providing an application for determining the body weight of a human person for installation on the evaluation unit or a device incorporating the evaluation unit.
