摘要
Calibration apparatus is described for use in a calibratable analytical system wherein a continuously flowing liquid sample, either alone or in admixture with other liquids, is normally caused to contact a sensor. The novel calibration apparatus enables diversion of said continuously flowing sample out of contact with the sensor and alternate contact of a calibration reference liquid or other calibration sample with the sensor. The calibration apparatus of the present invention is particularly useful in a system for analytical monitoring of a continuously flowing liquid blood sample obtained through a double lumen cannula inserted into a blood vessel of a human or animal subject. This apparatus permits the analytical system to be calibrated without the necessity of removing any portion of the cannula from the subject thereby avoiding the risk of loss of sterility inherent in such removal.
