Abstract: An optical access disconnect system (10) is useful for detecting the presence of blood. The optical access disconnect system includes one or more optical sensors (14) placed near an access site of a patient, the optical sensors suitable for detecting the presence of blood, especially by detecting a difference in light reflected or absorbed by blood. The optical access disconnect system may also be used as an interlock to assure compliance. A detector may be placed adjacent the access site to detect the access needle, or an object or mark on the access needle or fluid line. A therapy machine, such as a dialysis machine, may be programmed not to start or continue operation unless the needle or fluid line is detected. The detector may be one of the optical sensors, calibrated or adjusted to detect a mark on the needle or access line, or may be another type of detector.

Abstract: Un sistema de desconexi?n de acceso ?ptico (10) es ?til para detectar la presencia de sangre. El sistema de desconexi?n de acceso ?ptico incluye uno o m?s sensores ?pticos (14) colocados cerca de un sitio de acceso de un paciente, los sensores ?pticos adecuados para detectar la presencia de sangre, especialmente al detectar una diferencia en luz reflejada o absorbida por la sangre. El sistema de desconexi?n de acceso ?ptico tambi?n puede utilizarse como un bloqueo para asegurar el cumplimiento. Puede colocarse un detector adyacente al sitio de acceso para detectar la aguja de acceso, o un objeto o una marca en la aguja de acceso o l?nea de fluido. Una m?quina de terapia, tal como una m?quina de di?lisis, puede programarse para no iniciar o continuar la operaci?n al menos que se detecte la aguja o la l?nea de fluido. El detector puede ser uno de los sensores ?pticos, calibrados o ajustados para detectar una marca en la aguja o la l?nea de acceso, o puede ser otro tipo de detector.
