First Claim
Patent Images
1. A sensor comprising:
- a base layer configured to attach to a tissue location on a patient;
an emitter coupled to the base layer and positioned in a first aperture formed in the base layer;
a detector coupled to the base layer and positioned in a second aperture formed in the base layer; and
a plurality of adhesive layers coupled to the base layer, wherein the adhesive layers comprise respective cutouts, and wherein the respective cutouts are configured to be aligned with one another when the plurality of adhesive layers are coupled to the base layer, and wherein the cutout of each adhesive layer of the plurality of stacked adhesive layers comprises a ring shape that surrounds both the emitter and the detector such that there is no adhesive present in the direct optical path between the emitter and the detector.

Abstract
An optical sensor, having a cover layer, an emitter disposed on a first side of the cover, a detector disposed on the first side of said cover, and a plurality of stacked independent adhesive layers disposed on the same first side of the cover, wherein the top most exposed adhesive layer is attached to a patient'"'"'s skin. Thus, when the sensor is removed to perform a site check of the tissue location, one of the adhesive layers may also be removed and discarded, exposing a fresh adhesive surface below for re-attachment to a patient'"'"'s skin. The independent pieces of the adhesive layers can he serially used to extend the useful life of the product.
