Abstract

A living body measuring apparatus includes a plurality of electrodes each of which is structured to make contact with a part of a living body; a current source connected to the electrodes; a voltage measuring unit connected to the electrodes; a control unit connected to the current source and the voltage measuring unit; and a display unit connected to the control unit. The control unit instructs the display unit to display the part of the living body to which an electric current is fed to the current source via the associated electrodes. The control unit further instructs the display unit to display the part of the living body of which voltage is measured by the voltage measuring unit on the associated electrodes.

Claims

1. A living body measuring apparatus comprising:

a plurality of electrodes, each of which is for making contact with one of a plurality of parts of a living body;

a current source connected to said electrodes;

a voltage measuring unit connected to said electrodes;

a control unit connected to said current source and said voltage measuring unit; and

a display unit connected to said control unit;

wherein the control unit is for calculating a value of one or more health parameters for each of the plurality of parts of the living body based on the measured voltage; and

wherein said control unit is for instructing said display unit to display a representation of the plurality of parts of the living body and to simultaneously display the calculated value of one of the health parameters corresponding to each respective displayed part of the living body.

2. A living body measuring apparatus according to claim 1, wherein the control unit is for calculating a plurality of different health parameter values for each of the plurality of parts of the living body, further comprising a switching unit for selecting one of the health parameter values for each of the plurality of parts of the living body for display by the display unit.

3. A living body measuring apparatus according to claim 2, wherein the health parameter values include electrical impedance.

4. A living body measuring apparatus according to claim 2, wherein the health parameter values include body fat percentage.

5. A living body measuring apparatus according to claim 2, wherein the health parameter values include body fat amount.

6. A living body measuring apparatus according to claim 2, wherein the health parameter values include partial muscle amount.

7. A living body measuring apparatus according to claim 1, wherein the control unit is for instructing the display unit to display the calculated value of the one of the health parameters adjacent to each respective displayed part of the living body.

8. A living body measuring apparatus comprising:

a plurality of electrodes, each of which is for making contact with one of a plurality of parts of a living body;

a current source connected to said electrodes;

a voltage measuring unit connected to said electrodes;

a control unit connected to said current source and said voltage measuring unit; and

a display unit connected to said control unit;

wherein the control unit is for calculating values of a plurality of health parameters for each of the plurality of parts of the living body based on the measured voltage; and

wherein said control unit is for instructing said display unit to display a representation of the plurality of parts of the living body and to simultaneously display the calculated values of all of the health parameters corresponding to one displayed part of the living body.

9. A living body measuring apparatus according to claim 8, wherein the health parameter values include electrical impedance.

10. A living body measuring apparatus according to claim 8, wherein the health parameter values include body fat percentage.

11. A living body measuring apparatus according to claim 8, wherein the health parameter values include body fat amount.

12. A living body measuring apparatus according to claim 8, wherein the health parameter values include partial muscle amount.

13. A living body measuring apparatus according to claim 8, wherein the control unit is for instructing the display unit to display the calculated values of the health parameters adjacent to the one displayed part of the living body.

14. A living body measuring apparatus according to claim 8, further comprising a switching unit for selecting which one of the parts of the living body for which the health parameter values are to be displayed by the display unit.
