Patent ID: 6937889

Claim:
A pregnancy possibility determining apparatus comprising: a plurality of pairs of electrodes; a bioelectrical impedance meter; a bioelectrical impedance storing device; an ovulation decision-making unit or an ovulation presuming unit; a pregnancy decision-making unit; and a warning unit, wherein said pairs of electrodes can be applied to selected points of the outer layer of the skin of a woman's body; said bioelectrical impedance meter measures the value of the bioelectrical impedance appearing between one of said pairs of electrodes; said boielectrical impedance storing device stores the so measured values of bioelectrical impedance; said ovulation decision-making unit makes a decision as to when the woman has an ovulation day on the basis of a time-sequence transition or historical record of the values of bioelectrical impedance stored in the bioelectrical impedance storing device; or said ovulation presuming unit counts a predetermined number of days from the beginning of a next menstration period presumable from the time-sequence transition or historical record of the values of bioelectrical impedance stored in the bioelectrical impedance storing device, and said ovulation presuming unit presumes that the day so counted backward from the presumable beginning day of the next menstration period falls on the ovulation day; said pregnancy decision-making unit makes a decision of the possibility of pregnancy in terms of whether or not a predetermined number of days have passed from the ovulation day actually determined or presumed with the values of bioelectrical impedance remaining low; and said warning unit informs the woman of the result decision-making of the possibility of pregnancy.
