Abstract
A method and apparatus for detecting uterine contractions, determining the frequency of uterine contractions, trending the frequency data, and generating a real time graphical representation of the determined frequency. The invention employs commonly known methods of uterine activity detection. The uterine activity data is analyzed to determine the occurrence and frequency of contractions. The determined frequency of multiple time periods is displayed on a maternal/fetal monitor in real time over the course of labor.
Claims48
A monitoring device comprising:
- a sensor for acquiring uterine activity data;
- and
- an analysis module for determining the frequency of uterine contractions from the detected uterine activity data and for generating a time-frequency representation of the frequency of the uterine contractions.
A method of detecting and displaying uterine activity data, the method comprising the acts of:
- acquiring uterine activity data;
- determining the frequency of uterine contractions from the detected uterine activity data over a selected period of time;
- and
- generating a time-frequency representation of the frequency of the uterine contractions.
A monitoring device comprising:
- a uterine activity detector;
- a uterine contraction detection algorithm for determining the frequency of the detected uterine contractions over a selected period of time;
- and
- a display device for providing a user readable representation of the frequency of detected uterine contractions.
A uterine activity frequency trending software system comprising:
- a software-based data input module for receiving input data of uterine activity;
- and
- a software algorithm for determining the frequency of uterine contractions from the uterine activity data over a selected period of time and for generating output data of a time-frequency representation of the uterine contractions.
