And its fetal movement information processing apparatus can be recorded by detecting proper information about the movement of the fetus of a pregnant woman, to predict or know exactly the state well-being of the fetus of the (well-being) ie growth healthy state of the fetus I will provide a treatment method. Pregnancy age at calculating means 38 20, a signal obtained by detecting the fetal movement detection signal detection signal storage means for storing in association with the detection date information fetal movement detection signal detected by the 11 fetal movement sensor calculates the elapsed pregnancy-date, the The display and fetal movement amount measuring means 54 for measuring the fetal movement amount per unit time from fetal movement signal that is read from the detection information storage means, to can be displayed side by side in the gestational age for each fetal movement amount obtained by Momentum measuring means- and a configuration and output means 60.妊婦の胎児の動きに関する情報を適正に検出して記録し、胎児の健康な発育状態すなわち胎児のウエルビーイング(well-being)の状態を正確に把握ないし予想することができる胎動情報処理装置およびその処理方法を提供する。胎動センサ11によって検出された胎動検出信号を検出日情報と対応付けて記憶する検出信号記憶手段20、前記胎動検出信号を検出した信号が妊娠経過日を計算する妊娠経過日計算手段38と、前記検出情報記憶手段から読み出した胎動信号から単位時間当りの胎動量を測定する胎動量測定手段54と、該胎動量測定手段によって得られた胎動量を妊娠週数毎に並べて表示可能にする表示・出力手段60とを備えた構成からなる。
