First Claim
Patent Images
1. A weighing scale for determining the weight of a pregnant woman comprising:
- a height inputting unit for inputting the height of the pregnant woman;
a weight inputting unit for inputting her weight prior to conception;
a week-number inputting unit for inputting how many weeks have passed since conception;
a memory unit which stores antenatal weight data in terms of a body mass index;
an arithmetic unit which determines a most appropriate weight from the data inputted by said height, weight and week-number inputting units and the data retrieved from said memory unit; and
a display unit which displays the results of a calculation of the most appropriate antenatal weight.

Abstract
Disclosed is an improved weighing scale for determining a most appropriate antenatal weight of a pregnant woman for each number of the weeks since conception on the basis of the “antenatal weight-to-week” relationship identified in terms of the BMI of the pregnant woman, which index is determined from the height and progestational weight of the pregnant woman, and for making a comparison between the so determined most appropriate antenatal weight and the weight of the pregnant woman measured each week.

11. A weighing scale for determining the weight of a pregnant woman comprising:
- a height inputting unit for inputting the height of the pregnant woman;
a weight inputting unit for inputting her weight prior to conception;
a week-number inputing unit for inputting how many weeks have passed since conception;

an arithmetic unit which determines a most appropriate weight from the data inputted by said height, weight and week-numbered inputting units and the data retrieved from said memory unit, and which determines a most appropriate weight curve representing how the most appropriate antenatal weight varies with the number of weeks since conception and an instantaneous weight curve representing how the instantaneous weight varies with the number of weeks since conception; and
a display unit which displays the most appropriate weight curve and the instantaneous weight curve for comparison.

12. A weighing scale for determining the weight of a pregnant woman comprising:
- a unit which provides reference curves plotted for different BMIs each representing how the appropriate weight of non-pregnant women for a selected BMI varies with time, a weight scaling unit which weighs the instantaneous weight of the pregnant woman, and a display which shows how the instantaneous weight varies relative to the selected reference curve.
