    摘要: The present invention relates to an apparatus for monitoring blood parameters during cardio-pulmonary bypass surgery or during other procedures which utilize an extracorporeal circuit. The apparatus is typically used to monitor the percentage of hemoglobin bound with oxygen (oxygen saturation), the total amount of hemoglobin in the blood, and the percent of blood which is comprised of red blood cells (hematocrit), although the apparatus can be adapted to measure other blood parameters. The apparatus (or monitor) provides real-time results to show immediate changes (trending) in the monitored parameters.

    摘要: A heat exchanger for medical applications is disclosed. The heat exchanger is characterized in that it is configured to provide a high heat transfer efficiency while minimizing the possibility of formation gaseous emboli and maximizing the ability to entrap and remove any such emboli which form or are introduced into the device. The heat exchanger is particularly well-suited for use in connection with cardioplegia apparatus.
