A fetal movement information processing system comprising: a fetal movement signal collecting device including: at least one fetal movement sensor (11, 111) adapted to be attached to a pregnant woman's abdomen for detecting fetal movements; an inspecting means (13, 113) for inspecting whether or not the fetal movement sensor (11, 111) is normally operating; and a fetal movement detected information storage means (20, 120) storing fetal movement detection signals detected by said fetal movement sensor in association with detection time information indicating detection times of said fetal movement detection signals; respectively; a fetal movement information processing means (40, 50, 140, 150) calculating fetal movement amounts per unit time for each of pregnancy weeks of the pregnant woman from maternal information identifying the pregnant woman and number of pregnancy days information, along with the fetal movement detection signals and the detection time information stored in the fetal movement detected information storage means of said fetal movement signal collecting device; and a display/output means capable of arranging and displaying fetal movement amounts obtained by said fetal movement information processing means in order of pregnancy weeks, wherein said fetal movement information processing means further includes a database constructed in advance by calculating a mean value and a standard deviation of fetal movement amounts for each of the pregnancy weeks based on fetal movement information about fetal movements amounts per unit time for each of the pregnancy weeks collected from many pregnant women in advance, and said display/output means graphically displays fetal movement amounts obtained from the fetal movement signals collected from the pregnant women along with mean values and standard deviations obtained from said database, and wherein said fetal movement information processing means further includes a fetal movement information rectifying/integrating means configured to rectify the fetal movement signals and integrate them every unit time and calculate fetal movement amounts per unit time based on fetal movement information including obtained integrated values. a fetal movement signal collecting device including: at least one fetal movement sensor (11, 111) adapted to be attached to a pregnant woman's abdomen for detecting fetal movements; an inspecting means (13, 113) for inspecting whether or not the fetal movement sensor (11, 111) is normally operating; and a fetal movement detected information storage means (20, 120) storing fetal movement detection signals detected by said fetal movement sensor in association with detection time information indicating detection times of said fetal movement detection signals; respectively; a fetal movement information processing means (40, 50, 140, 150) calculating fetal movement amounts per unit time for each of pregnancy weeks of the pregnant woman from maternal information identifying the pregnant woman and number of pregnancy days information, along with the fetal movement detection signals and the detection time information stored in the fetal movement detected information storage means of said fetal movement signal collecting device; and a display/output means capable of arranging and displaying fetal movement amounts obtained by said fetal movement information processing means in order of pregnancy weeks, wherein said fetal movement information processing means further includes a database constructed in advance by calculating a mean value and a standard deviation of fetal movement amounts for each of the pregnancy weeks based on fetal movement information about fetal movements amounts per unit time for each of the pregnancy weeks collected from many pregnant women in advance, and said display/output means graphically displays fetal movement amounts obtained from the fetal movement signals collected from the pregnant women along with mean values and standard deviations obtained from said database, and wherein said fetal movement information processing means further includes a fetal movement information rectifying/integrating means configured to rectify the fetal movement signals and integrate them every unit time and calculate fetal movement amounts per unit time based on fetal movement information including obtained integrated values.
