ABSTRACT:
A device for detecting, monitoring, displaying and recording a representation of the heartbeats of a pregnant woman and her fetus. The heartbeat of each is monitored. Detecting of the woman's heartbeat activates a display of a representation of the heartbeat and enables circuitry which displays a representation of the detected fetal heartbeat. Preferably two different types of sensors are used, for example an infra-red sensor for the woman's heartbeart and an audio sensor for the fetal heartbeat. The displays can depict hearts pulsating at rates corresponding with the respective heartbeats, or can present numerical displays of the heartbeat rates. In addition, a third sensor can detect movement of the fetus and can activate a display of a moving infant or a numerical display of the movement intensity or frequency. A combination of any of these displays can be presented. Signals representative of the detected heartbeats and movement can be recorded for later playback. A microphone and speaker permit the woman to provide audio stimulation to the fetus, and the fetal response to this stimulation can then be monitored.
