MEDICAL SENSOR FOR REDUCING MOTION ARTIFACTS AND TECHNIQUE FOR USING THE SAME
First Claim
Patent Images
1. A sensor comprising:
- a sensor body;
an emitter and a detector disposed on the sensor body and adapted to be positioned proximate to a tissue of a patient; and
a motion damping structure comprising a foam or a viscoelastic material disposed on an exterior surface of the sensor body, such that the motion damping structure is visible and faces away from the tissue when the sensor is applied to the patient, wherein the motion damping structure is capable of damping a force experienced by the sensor body, such that the motion damping structure moves at least partially independently of the emitter and the detector when an external force is applied to the motion damping structure.

Abstract
A sensor may be adapted to reduce motion artifacts by damping the effects of outside forces and sensor motion. A sensor is provided with a motion damping structure adapted to reduce the effect of motion of a sensor emitter and/or detector. Further, a method of damping outside forces and sensor motion is also provided.

14. A sensor comprising:
-
a rigid clip-style sensor body; an emitter and a detector disposed on an interior surface of the sensor body, wherein the interior surface is adapted to be proximate to a patient'"'"'s tissue when the sensor is applied; and a motion damping structure comprising a foam or a viscoelastic material disposed on an exterior surface the sensor body, wherein the exterior surface of the sensor body is opposite the interior surface, and wherein the motion damping structure is capable of damping a force experienced by the sensor body, such that the motion damping structure moves at least partially independently of the emitter and the detector when an external force is applied to the motion damping structure. - View Dependent Claims (15, 16, 17, 18, 19, 20)
