1. A finger holder to be used in an optical measurement device for non-invasive measurement of blood parameters, the finger holder comprising:

  • a clip member for securing a fingertip between its legs and supporting a measuring unit having an illumination-detection assembly for illuminating a first location of a finger, detecting light response of the illuminated location and generating data representative thereof;

    a pressurizing assembly capable of applying desired over-systolic pressure to a second location on the finger upstream of said first location with respect to a normal blood flow direction; and

    a substantially rigid connector between the clip member and the pressurizing assembly, the connector being adapted to engage the finger along its middle phalanx and proximal intephalangeal joint, thereby preventing it from folding during the measurements.
