Stacked adhesive optical sensor
First Claim
1. A sensor comprising:
- a sensor body; and
an emitter and a detector coupled to the sensor body, wherein the sensor body is configured to hold the emitter and the detector at a substantially fixed distance relative to one another when the sensor is applied to a patient.

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 reattachment to a patient'"'"'s skin. The independent pieces of the adhesive layers can be serially used to extend the useful life of the product.
