Abstract
The device comprises a sensor with a mirror coupled to a diaphragm used to shift the mirror according to the patient's heart and thorax movements. A light generator illuminates the mirror. An electro-optical detector converts the intensity of the light rays reflected by the mirror into an electrical signal and a processing circuit generates output signals indicative of heart and respiratory movements.
