COUGH DETECTION SYSTEM, METHOD, AND DEVICE

Abstract A wearable apparatus for a patient for use in cough detection, comprising: a movement sensor configured to generate measurements of a movement of the patient, the movement sensor configured to be worn by the patient; a sound sensor configured to generate measurements of breathing sounds of the patient; a controller interfaced with the movement sensor and the sound sensor; and a housing for locating the movement sensor, sound sensor, and controller, wherein the controller is configured to: obtain a movement signal corresponding to the measurements of the movement of the patient made by the movement sensor; obtain a sound signal corresponding to the measurements of the breathing sounds of the patient made by the sounds sensor; generate thoracic movement data from the movement signal; generate breathing data from the sound signal; and generate respiratory data comprising the thoracic movement data and the breathing data, and further comprising correlation information configured to enable identification of contemporaneous breathing events within the thoracic movement data and the breathing data; provide correlated respiratory data to a processing module configured for identifying specific breathing events at least including coughing events, such that a coughing event is identifiable from the correlated respiratory data according to a coincidence of identification of a predefined sound pattern within the breathing data and identification of a predefined movement pattern within the thoracic movement data. 20694546_1 (GHMatters) P117019.AU.1 Initiate controller into ACTIVE mode Initiate sensors Continuously monitor sensors and provide output to processing module Process signals Cough detected?
