US Patent 10226191 Newborn heart rate monitor

A newborn heart rate monitor is disclosed comprising a sensor integrated into a clamp configured to clamp onto the umbilical cord of a newborn infant. The sensor is configured to detect radial pulsation of the umbilical cord and produce a corresponding electrical signal which can be processed by a processor to calculate the heartbeat of the newborn infant. The heartbeat can be displayed visually or audibly or both. A second reference sensor can be included to detect environmental noise and the processor can be configured to use the detected environmental noise to filter noise from the detected heartbeat. Additional filtering, processing, and alert algorithms can be included for processing and analyzing the detected heartbeat data.
