    • An apparatus for measuring the blood parameters in an extracorporeal circuit comprises: a seat (23) suitable for containing a duct (14) for the blood flow of said extracorporeal circuit; emitting means (16) and detecting means (18) of electromagnetic radiation that face the seat (23); a control unit (38) to which said emitting means (16) and detecting means (18) are connected. The apparatus according to the invention is characterised in that the emitting means (16) are suitable for producing electromagnetic radiation at different wavelengths, and the detecting means (18) are suitable for detecting the electromagnetic radiation diffused in the blood at said wavelengths. Moreover, the apparatus is characterised in that the control unit (38) is suitable for calculating values of blood parameters through a correlation between reference values and ratios obtained from values of the light intensity of the radiation detected at at least two different wavelengths.
    • 一种用于测量体外回路中的血液参数的装置包括:适于容纳用于所述体外回路的血流的管道(14)的座(23); 发射装置(16)和面对座椅(23)的电磁辐射的检测装置(18)。 控制单元(38),所述发射装置(16)和检测装置(18)连接到该控制单元。 根据本发明的装置的特征在于,发射装置(16)适于产生不同波长的电磁辐射,并且检测装置(18)适用于检测在所述波长处扩散在血液中的电磁辐射。 此外,该装置的特征在于,控制单元(38)适用于通过从至少两个不同波长处检测的辐射的光强度获得的参考值和比值之间的相关性来计算血液参数的值。
