Optical device for the simultaneous detection of heart and respiratory movements
First Claim
1. An optical device for the simultaneous detection of heart and respiratory movements, comprising a sensor comprising a movable mirror coupled to means used to move the mirror according to heart and respiratory movements, a light generator coupled to light guide means, to illuminate the mirror, and electro-optical means also coupled to the light guide means, to convert intensity of a light beam reflected by the mirror into an electrical signal, and processing means for receiving the electrical signal and converting this signal into output signals respectively indicative of heart and respiratory movements.

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.
