PROBLEM TO BE SOLVED: To provide a pregnancy state monitoring system capable of detecting a uterus contract state (a state of contraction) by a non-invasive method giving no inconvenience or discomfort to a pregnant woman and having no trouble of attachment or no possibility of falling.SOLUTION: The pregnancy state monitoring system for monitoring states of a mother body on a placement table and/or a fetus within the uterus of the mother body, includes: a plurality of load detectors provided on the placement table or under the legs of the placement table for detecting temporal variations in loads of the mother body and fetus a signal analysis part for acquiring frequency spectra of the time variations in the loads of the mother body and fetus and a state monitoring part for determining whether the uterus of the mother body is contracted or not on the basis of the acquired frequency spectra.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】子宮の収縮の様子(陣痛の様子)を、妊婦に不便や不快感を与えることのない非侵襲な方法で検出することができ、且つ取付けの手間や脱落の恐れのない妊娠状態モニタリングシステムを提供する。【解決手段】載置台の上の母体且つ/又は該母体の子宮内の胎児の状態をモニターする妊娠状態モニタリングシステムは、載置台又は載置台の脚下に設けられ、前記母体及び前記胎児の荷重の時間的変動を検出する複数の荷重検出器と、前記母体及び前記胎児の荷重の時間的変動の周波数スペクトルを求める信号解析部と、前記求められた周波数スペクトルに基づいて前記母体の子宮に収縮が生じているか否かを判定する状態監視部とを備える。【選択図】図1
