ABSTRACT:
A device for non-invasively monitoring blood flow comprising a support member having a base surface for engaging the skin, and a light source and a light detector which are supported by the support member above the base surface thereof. The light source emits a beam of light in the form of a cone of relatively small angle, and the light detector receives light directed there towards within a collection cone of relatively large angle. The axis of the light beam crosses the axis of the collection cone below the base surface.
