SAETT OCH SENSOR FOER DETEKTERING AV SPECIFIKA PARAMETRAR HOS CIRKULERANDE BLOD INUTI EN LEVANDE ORGANISM

摘要

The invention relates to method and sensor for detecting specific parameters of a blood flow in a blood vessel in a living organism by detecting optical properties of the flowing blood, depending on said specific parameter, by using at least one optical plastic or glass fibre. The detection is effected according to the invention in a peripheral layer of blood plasma closest to the wall of the blood vessel the optical fiber being disposed adjacent said wall at the outside or inside surface thereof. The sensor comprises means (10) for applying one or more optical plastic or glass fibres (14, 15) to the outside surface of the wall of the blood vessel (11).
