Abstract

A display of the quantities of bone, water and/or muscle and a pulse health instrument in which the weight of bone or the weight rate of bone, the quantity of water and/or the quantity of muscle are measured and displayed to serve for sound diet and health management. Body fat rate is calculated by measuring the body impedance, quantity of bone, weight of bone, weight rate of bone, quantity of water and/or quantity of muscle are calculated based on the body fat rate and personal information inputted from a user, e.g. sex, age, height, body weight, length around wrist, length around ankle, and the like, and the results are displayed at a display section 105. Furthermore, the type of quantity of bone based on the correlation between the weight rate of bone and the body weight is judged and displayed in the matrix display region 111 of the display section 105.

Claims

1. A display equipment for displaying the characteristics of a body including the quantities of the bone, the water and/or the muscular of the body, comprising:

a plurality of electrodes in contact to the surface of the body;

means for measuring the impedance of the body by feeding a measuring current through said plurality of the electrodes into the body;

means for putting the personal information such as male or female, age, height, body weight, length around the wrist, length around the hand of the body to be measured into the display equipment;

means for calculating each approximate value of the bone weight, the water weight and/or muscular weight of the body on the basis of the impedance as measured and said personal information;

means for judging the somatotypes of the body which are classified on the basis of the correlations between the approximate value as calculated and the body weight; and

a display for indicating the somatotype as judged by said judging means.

2. The display equipment for displaying the characteristics as set forth in claim 1,

wherein said personal information include at least male or female and the age, and the combination thereof.

3. The display equipment for displaying the

characteristics as set forth in claim 1 or 2,

wherein said display equipment includes a memory of recording the bone weight, the water weight and/or the muscular weight of the body, which have been calculated on the basis of the impedance as measured, and said personal information, and further, a display of indicating sequentially the data as calculated.

5. The display equipment for displaying the characteristics as set forth in claim 1 or 2,

wherein the equipment can feed a pulsed current through said plurality of electrodes into the body, so as to treat the body.

6. The display equipment for displaying the characteristics as set forth in claim 3,

wherein the equipment can feed a pulsed current through said plurality of electrodes into the body, so as to treat the body.
