Abstract

A sensor for physiological constituent detection may be adapted to include a mucoadhesive. A sensor is provided that is appropriate for use on mucosal tissue. The mucoadhesive provides a mechanism for holding the sensor on the mucous membrane in order to measure physiological constituent levels in the tissue and blood.

Claims (10)

1. A method comprising:

securing a sensor to a mucosal tissue with a mucoadhesive, wherein the sensor comprises an indicator adapted to provide feedback related to a physiological constituent, and wherein the mucoadhesive is disposed on a tissue-contacting side of the indicator, wherein the indicator comprises an emitter and a detector disposed on the tissue-contacting surface and wherein the mucoadhesive is in direct contact with the emitter and detector.

2. The method, as set forth in claim 1 , wherein the physiological constituent comprises at least one of a tissue or blood constituent.

3. The method, as set forth in claim 1 , wherein the physiological constituent comprises at least one of a metabolic trace gases or an anesthetic gas.

4. The sensor, as set forth in claim 1 , wherein the physiological constituent comprises at least one tissue metabolite.

5. The sensor, as set forth in claim 1 , wherein the physiological constituent comprises at least one of carboxyhemoglobin or methemoglobin.

6. The method, as set forth in claim 1 , wherein the sensor comprises at least one of a pulse oximetry sensor or a carbon dioxide sensor.

7. The method, as set forth in claim 6 , comprising assessing the presence of carbon dioxide by viewing an indicator through an optically transparent layer.

8. The method, as set forth in claim 6 , comprising assessing the presence of carbon dioxide by providing an electrical feedback.

9. The method, as set forth in claim 1 , comprising detaching the sensor by applying a solvent to the mucosal tissue.
