ABSTRACT:
A sensor for use with instruments that non-invasively measure blood constituents, particularly oxygen saturation of arterial blood from the patient's tissue. The sensor has two rigid housings adapted for arrangement in opposition and secured about a patient's tissue. Each housing has a deformable pad adapted for receiving, conforming to, and securely gripping the patient's tissue without significantly affecting arterial blood flow. In one embodiment, the housings are pivotally mounted and biased closed under tension, one pad contains a light source for illuminating the tissue in its tissue contacting surface, and the other pad contains the light detector for use in measuring the amount of light absorbed by the blood constituent. In a second embodiment one or the other pad contains both the light source and light detector. The detected light can then be correlated to the amount of blood constituent present in the blood.
