Appraisal of the fetus reactivity with the analysis of fetus heart beat frequency

摘要

This invention fetus heart beat frequency (FHR) relates to the field which is monitored, details seem like the pattern which for example appears when giving birth, it regards the monitoring of the pattern in during period of generally known unstationary state of fetus heart beat frequency. This invention, in order early to be able to appraise fetus pain just, more clearly analyzes FHR fluctuation the device which is improved, offers method and the computer program. According to one feature, this invention includes the expedient which measures fetus heart beat frequency and the expedient which identifies the primary fetus heart beat frequency component and, subtraction doing the primary component from the fetus heart beat frequency which is measured, the expedient which analyzes the heart beat interval fluctuation of fetus heart beat frequency with the expedient which decides the residual component and making use of the aforementioned residual component.
