Abstract

A device for supervision of the respiration of infants is based on the principle that the breathing sounds are detected by means of a signal microphone (10) adapted on the infant's throat. In order to eliminate the influence of disturbing surrounding sounds a reference microphone (12) is positioned on the infant so that it picks up substantially the same disturbing sounds as the signal microphone (10) but substantially no breathing sounds. By subtraction of the reference microphone signal from the output signal or the signal microphone, e.g. in a differential amplifier (30), an output signal indicating the respiration and substantially independent of disturbing sounds is formed which can be made to sound the alarm via suitable signal treatment circuits (32, 34) when the breathing sounds have ceased for a predetermined time.
