Shrouded sensor clip assembly and blood chamber for an optical blood monitoring system

A system for monitoring extracorporeal blood flow, the system comprising:

• a blood chamber comprising:
• an inlet, an outlet and an internal blood flow cavity;
• a main body made of a material having an opaque color, the opaque color of the material being configured to attenuate ducting of light through the main body;
• and
• a first lens and a second lens, wherein the first and second lenses are constructed as mirror images of one another, and wherein the first lens is disposed in a first recess of the main body and the second lens is disposed in a second recess of the main body;
• wherein the internal blood flow cavity is disposed within a space within the main body between the first and second lenses;
• and
• a sensor clip assembly, comprising two opposing arms configured to be mated to the blood chamber so as to attach the sensor clip assembly to the blood chamber;
• wherein the system further comprises an anti-rotation tab and an anti-rotation slot for preventing rotation of the sensor clip assembly relative to the blood chamber while the sensor clip assembly is attached to the blood chamber, wherein the anti-rotation tab extends inwardly from a peripheral wall of at least one of the first and second lenses, and wherein the anti-rotation slot corresponds to the anti-rotation tab and is disposed on at least one of the two opposing arms of the sensor clip assembly.
