1. A maternal labor pain management system comprising:
- a) at least one analgesic pain management means;
b) a system for administering the pain management means, wherein the system for administering the pain management means is a patient controlled system; and
c) a system for analyzing uterine activity in the prediction of labor contractions to predict time of contraction onset relevant for use in coordinating the administration of the pain management means, wherein the system for analyzing uterine activity provides at least one signal regarding the predicted time of contraction onset and wherein the system for analyzing uterine activity is operably connected to the system for administering the pain management means, wherein the system for analyzing uterine activity comprises;
i) at least two abdominal electrode sensors to receive a mixture of maternal and fetal vital signals; and
ii) a computing means for analyzing the mixture of maternal and fetal vital signals from the sensors, said computing means including hardware and software, wherein said software comprises a function to extract electrohysterogram (EHG) data from the maternal and fetal vital signals for use in determining the predicted time of contraction onset, andwherein the system for administering the pain management means is responsive to the predicted time of contraction onset determined by the computing means to automatically initiate and cease the delivery of the analgesic pain management means.

6. A method for administering an analgesic to an obstetric patient, where said method comprises:
-
a) utilizing a maternal labor pain management system comprising; 1) at least one analgesic pain management means; 2) a system for administering the pain management means; and 3) a system for analyzing uterine activity in the prediction of labor contractions to predict time of contraction onset relevant for use in coordinating the administration of the pain management means, wherein the system for analyzing uterine activity provides at least one signal regarding the predicted time of contraction onset and wherein the system for analyzing uterine activity is operably connected to the system for administering the pain management means, wherein the system for analyzing uterine activity comprises; i) at least two abdominal electrode sensors to receive maternal and fetal signals; and ii) a computing means for analyzing the maternal and fetal signals from the sensors, said computing means including hardware and software, wherein said software comprises a function to extract electrohysterogram (EHG) data from the maternal and fetal signals for use in determining the predicted time of contraction onset, and wherein the system for administering the pain management means is responsive to the predicted time of contraction onset determined by the computing means to automatically initiate and cease the delivery of the analgesic pain management means, and b) receiving into the computing means signals received by the abdominal electrode sensors; c) implementing the computing means, without clinician input, to evaluate the signals to determine the predicted time of contraction onset; and d) recommending, without clinician input, a time for administering the analgesic pain management means based on the predicted time of contraction onset, wherein said administration time is appropriate for the patient at that particular contraction. - View Dependent Claims (7, 8, 9, 10, 11, 12, 13, 14, 15, 16)

17. A maternal labor pain management system comprising:
-
a) at least one analgesic pain management means having a pain-relieving ability; b) a system for administering the pain management means; and c) a system for analyzing uterine activity in the prediction of labor contractions to predict any one or more of the following contraction data selected from the group consisting of; contraction frequency, contraction duration, contraction intensity, time of history of contractions, and extent and/or intensity of contraction-induced pain that is relevant for use in coordinating the administration of the pain management means, wherein the system for analyzing uterine activity provides at least one contraction data signal and wherein the system for analyzing uterine activity is operably connected to the system for administering the pain management means, wherein the system for analyzing uterine activity comprises; i) at least two abdominal electrode sensors to receive a mixture of maternal and fetal vital signals; and ii) a computing means for analyzing the mixture of maternal and fetal vital signals from the sensors, said computing means including hardware and software, wherein said software comprises a function to extract electrohysterogram (EHG) data from the maternal and fetal vital signals for use in predicting contraction data, and wherein the system for administering the pain management means is responsive to the predicted contraction data signal to automatically initiate and cease the delivery of the analgesic pain management means such that the pain relieving ability of the analgesic coincides with the predicted contraction data. - View Dependent Claims (18, 19, 20, 21, 22)
