Abstract

The medical device for measuring a patient's breathing employs a sensing head, held in contact with the patient's throat. This houses an electret which senses acoustic signals, and passes the signals to an amplifier followed by a converter which supplies electrical signals to a measuring or indicating device. The head has a hood (6) with a front contact plate (7) with holes (8) through it, communicating with a chamber containing the electret (9). This consists of a charged dielectric thin film mounted above a counter electrode (10) with holes (11) through it. The chamber is closed by a bottom plate (16). Connections (14, 19) are made to the hood and to the counter electrode.
