Wireless fetal monitoring system
First Claim
1. A wireless fetal and maternal monitoring system comprising:
- a fetal sensor unit adapted to provide signals indicative of a fetal heartbeat,a contraction sensor adapted to provide signals indicative of a maternal uterine contraction upon a maternal uterine contraction,a digitization and control unit, the digitization and control unit adapted to receive the signals indicative of a fetal heart rate and the signals indicative of a maternal uterine contraction, the digitization and control unit including a heart rate calculation system to calculate the fetal heart rate, a fetal heart rate register for storing the calculated fetal heart rate, a microcontroller configured to refresh per fetal heartbeat the fetal heart rate register, a maternal uterine contraction register to store the signals indicative of maternal uterine contraction, the digitization and control unit providing data fusion by transmitting at least the calculated fetal heart rate from the fetal heart rate register and data based on the signals indicative of the maternal uterine contraction from the maternal uterine contraction register;
a short-range transmission unit adapted to receive from the digitization and control unit the fused data signals and to retransmit the signals,a microphone comprising a maternal heartbeat sensor, anda processor including a comparator and a flag memory to eliminate as an erroneous measure a first sensed beat period by comparison to a second sensed beat period and to set a flag in the flag memory.

Abstract
A wireless fetal and maternal monitoring system includes a fetal sensor unit adapted to receive signals indicative of a fetal heartbeat, the sensor optionally utilizing a Doppler ultrasound sensor. A short-range transmission unit sends the signals indicative of fetal heartbeat to a gateway unit, either directly or via an auxiliary communications unit, in which case the electrical coupling between the short-range transmission unit and the auxiliary communications unit is via a wired connection. The system includes a contraction actuator actuatable upon a maternal uterine contraction, which optionally is a EMG sensor. A gateway device provides for data visualization and data securitization. The gateway device provides for remote transmission of information through a data communication network. A server adapted to receive the information from the gateway device serves to store and process the data, and an interface system to permits remote patient monitoring.
