1. A noninvasive, electrooptical sensor probe for removable attachment to the skin of a patient to measure light extinction during transillumination of the blood-perfused tissue beneath the skin, comprising:

  • a flexible, substantially U-shaped, support structure having spaced, opposed upper and lower inner surfaces;

    a light source mounted in said support structure and positioned to emit light from one of said inner surfaces;

    a photosensor mounted in said support structure and positioned on the other of said inner surfaces to detect light emitted by said light source;

    means for electrically connecting said light source and said photosensor to an external device;

    means for removably securing said support structure to the skin; and

    a generally U-shaped, highly resilient alignment mementer disposed in said support structure to impart a U-shape thereto, which alignment member extends substantially from said light source to said photosensor.
