a circulation circuit having a conduit through which the blood is transferred; and
a pressure measuring device comprising:
a main body portion adapted to detachably and movably mount onto the conduit;
an elastically-deformable pressure receiver body within the main body portion adapted to deform according to the pressure of the blood;
a polarizer disposed in the main body portion so that light oscillating in a predetermined direction passes therethrough;
an image acquisition unit disposed in the main body portion to acquire image information of the elastically-deformable pressure receiver body through the polarizer as the elastically-deformable pressure receiver body is deformed in response to the pressure of the blood; and

a control unit configured to convert the image information acquired by the image acquisition unit into pressure information.
