Abstract: A device for sensing the occurrence and magnitude of coughs. The cough sensor is contained within an annular housing having internally mounted sensing means resiliently biased to axially extend beyond the housing. Electrical actuation of circuit means by longitudinal movement of the sensing means generates signals. The device is secured to a predetermined location on the patient's body by a belt suitably attached thereto or other appropriate means capable of retaining the device in close proximity to a body muscle involved in the production of coughs.
