Abstract
An apparatus comprising a supporting structure having a surface, an optical sensor for sensing a compositional blood parameter and a deformable optical coupling element carried by the supporting structure. The optical sensor is carried by the supporting structure and is responsive to an optical input signal to provide an optical output signal related to the compositional blood parameter. The optical coupling element is in a position to receive at least one of the optical signals and the optical coupling element is transmissive to such received signal.
