The present invention is directed to a non-invasive method and apparatus for measuring arterial and venous blood flow in body appendages. The present invention is also directed to a non-invasive method and apparatus for measuring penile tumescence as a function of arterial and venous blood flow in the penis and penile rigidity as a function of suprasystolic intra-cavernosal pressure. These measurements are performed to make a diagnosis in the field of erectile dysfunctions. Since every normal adult male experiences erections during rapid eye movement sleep, the measurements are preferably made during the patient's sleep, but can also be performed when the patient is awake for diagnosis and treatment.

La présente invention porte sur une méthode et un appareil non effractifs pour mesurer le débit sanguin artériel et veineux dans les appendices du corps. Cette invention porte également sur une méthode et un appareil non effractifs pour mesurer la tumescence pénienne en tant que fonction du débit sanguin artériel et veineux dans le pénis et la rigidité pénienne en tant que fonction de la pression intra-caverneuse suprasystolique. Ces mesures sont prises pour établir un diagnostic dans le domaine des dysérections. Puisque tous les hommes adultes ont des érections durant le sommeil paradoxal, les mesures sont prises de préférence pendant le sommeil du patient. Toutefois, les mesures peuvent également être prises lorsque le patient est éveillé pour établir un diagnostic et un traitement.
