Passive phonography heart monitor

摘要

A fetal heart monitor device includes a channel to receive a first signal representative of acoustic energy principally from a maternal heartbeat and a second signal representative of acoustic energy including a fetal heart beat. The device includes a computing device including a processor, a memory operatively coupled to the processor and non-volatile storage operatively coupled to the processor, the non-volatile storage storing a computer program including instructions to cause the processor to process the first and second electrical signals into an electrical signal representative of the acoustic energy emitted by the fetal heart.
