1. A method of applying a sensor, comprising:
- providing a flexible sensor body to which an emitter and a detector are coupled, wherein the flexible sensor body is coupled to a plurality of stacked adhesive layers, wherein no portion of the plurality of stacked adhesive layers is in the direct optical path between the emitter and the detector, and wherein 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;
removing the first adhesive layer from the plurality of stacked adhesive layers, wherein removing the first adhesive layer exposes a second adhesive layer within the plurality of stacked adhesive layers; and
applying the second adhesive layer to a patient, wherein the second adhesive layer is configured to secure the flexible sensor body to the patient'"'"'s skin.

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 be serially used to extend the useful life of the product.

13. A method of manufacturing a pulse oximetry sensor, comprising:
-
providing a flexible sensor body to which an emitter and a detector are coupled; providing a plurality of adhesive layers coupled to the sensor body, wherein no portion of the plurality of adhesive layers is in the direct optical path between the emitter and the detector, and wherein 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; and providing each of the plurality of adhesive layers with respective non-adhesive tabs, wherein a first non-adhesive tab is configured to separate a first adhesive layer from the plurality of adhesive layers to expose a second adhesive layer within the plurality of adhesive layers. - View Dependent Claims (14, 15, 16, 17, 18, 19)
