摘要：
Systems and sensor clip assemblies for optically monitoring blood flowing through a blood chamber are provided. A sensor clip assembly includes emitters and photodetectors positioned on opposing arms, a signal conditioning circuit for conditioning raw analog signals generated by the photodetectors while the sensor clip assembly is fastened to a blood chamber, and an analog-to-digital converter for converting the conditioned analog signals to raw digital data. The sensor clip assembly may include a microcontroller for calculating parameters of blood flowing through the blood chamber such as hematocrit, oxygen saturation, and change in blood volume from the raw digital data. The sensor clip assembly is in communication with a networked computer, and the networked computer is in communication with a remote computer configured to provide a user interface for monitoring and/or controlling the sensor clip assembly.
