Fetal monitoring system and method
First Claim
1. A system for monitoring the condition of a fetus, the system comprising:
- (a) a plurality of sensors each of said sensors being deployable so as to generate an output indicative of a physiological parameter;
(b) a processing unit associated with all of said sensors, said processing unit being configured;
(i) to process said outputs to derive at least one calculated parameter related to fetal well-being, and(ii) to apply fetal well-being test criteria to said at least one calculated parameter to identify occurrence of an alarm condition; and
(c) a monitoring unit associated with said processing unit, said monitoring unit being responsive to identification of an alarm condition to generate an alarm signal,wherein said fetal well-being test criteria include at least one multiple-level threshold test wherein an alarm condition is identified both when a first of said at least one calculated parameter passes a first threshold level for in excess of a first time period and when said first calculated parameter passes a second threshold level differing from said first threshold for in excess of a second time period longer than said first time period.

Abstract
A system and method for monitoring the condition of at least one fetus is provided. The fetal monitoring system includes a plurality of fetal well-being sensors, each of which detects signals during a monitoring period. The system also includes at least one interface unit, a central processing unit connected to the interface unit and a monitoring unit connected to the central processing unit. The interface unit is connected to the fetal well-being sensor for transmitting the detected signals. The central processing unit includes means for receiving and processing the signals . The monitoring unit enables the medical staff to monitor the transmitted and processed signals.

11. A system for monitoring the condition of at least one fetus, the system comprising:
-
(a) a plurality of sensors each of said sensors being deployable so as to generate an output indicative of a physiological parameter, said plurality of sensors including a fetal heart activity sensor; (b) a processing unit associated with all of said sensors, said processing unit including a database of fetal heart rate patterns indicative of fetal distress, said processor unit being configured; (i) to process said outputs to derive at least a measured fetal heart rate pattern, and (ii) to compare said measured fetal heart rate pattern with said fetal heart rate patterns indicative of fetal distress to identify occurrence of an alarm condition; and (c) a monitoring unit associated with said processing unit, said monitoring unit being responsive to identification of an alarm condition to generate an alarm signal.
