Abstract

L'invention concerne un appareil et un procédé permettant de contrôler la fréquence cardiaque foetale et de surveiller la fréquence cardiaque et les contractions utérines de la mère, grâce à des formes d'onde biopotentielles, qui indiquent la fréquence cardiaque de la mère, produites par des capteurs placés sur ou à proximité de la poitrine de la mère, ces formes d'onde indiquant par ailleurs les fréquences cardiaques de la mère et du foetus détectées par des capteurs disposés sur l'abdomen ou le bas du dos de la mère, voire sur les deux. Les signaux émis par ces capteurs abdominaux sont divisés en plusieurs voies, un algorithme ASPF (filtre de traitement de signaux adaptatif), ou tout autre algorithme approprié, étant ensuite utilisé pour effacer la forme d'onde maternelle estimée à partir de chaque voie dérivée de ces capteurs abdominaux. Puis ce système sélectionne, à partir des formes d'onde obtenues, au moins une forme d'onde destinée à servir de forme d'onde foetale de référence. Cette forme d'onde de référence est ensuite comparée aux autres formes d'onde, de préférence à l'aide dudit algorithme ASPF, de manière à former un signal foetal amélioré représentant l'électrocardiogramme biopotentiel foetal (EKGf), qui peut être utilisé ultérieurement pour mesurer la fréquence cardiaque foetale ainsi que d'autres paramètres du profil biophysique. Enfin, les signaux électromyographiques (EMG) superficiels permettent à la fois de surveiller les contractions utérines et de réduire efficacement les artefacts dus aux mouvements.
