Stacked adhesive optical sensor
View Patent ↗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.
1. A sensor comprising:
a generally annulus-shaped base, the base configured to attach to a tissue location on a patient;
a lid connected by a hinged connection at its near end with a near end of the base;
an emitter disposed on a first side of the lid;
a detector disposed on the first side of the lid; and
a clasp connected with a far end of the lid and configured to engage a far end of the base.
2. The sensor of claim 1 comprising an adhesive layer disposed on a first side of the generally annulus-shaped base, the adhesive layer configured to adhere to a tissue location on a patient.
3. The sensor of claim 1 comprising a plurality of stacked independent adhesive layers disposed on a first side of the generally annulus-shaped base, the adhesive layers configured to adhere to a tissue location on a patient.
4. The sensor of claim 1 wherein the sensor is configured to operate in a first mode and a second mode,
wherein in the first mode the clasp engages the base, and the lid and the base together form a substantially flat sensor, and
wherein in the second mode, the clasp is disengaged from the base and the lid is lifted from the tissue location.
5. The sensor of claim 1 wherein the sensor comprises an oximeter sensor.
6. The sensor of claim 1 wherein the clasp engages the base via a mechanical clasp-type connection.
7. The sensor of claim 1 wherein the clasp adhesively engages the base.
8. A sensor comprising:
a base having an opening therein;
a lid sized to be disposed in the opening in the base, wherein one end of the lid is connected to the base by a pivotal connection;
a clasp connected with another end of the lid, the clasp configured to engage the base;
an emitter coupled to the lid; and
a detector coupled to the lid.
9. The sensor of claim 8 comprising an adhesive layer disposed on a first side of the base, the adhesive layer configured to adhere to a tissue location on a patient.
10. The sensor of claim 8 comprising a plurality of stacked independent adhesive layers disposed on a first side of the base, the adhesive layers configured to adhere to a tissue location on a patient.
11. The sensor of claim 8 wherein the sensor is configured to have at least a first position and a second position,
wherein in the first position the clasp engages the base, and the lid and the base together form a substantially fiat sensor, and
wherein in the second position, the clasp is disengaged from the base and the lid is pivotally lifted from a tissue location on a patient.
12. The sensor of claim 8 wherein the sensor comprises an oximeter sensor.
13. A sensor comprising:
a flexible base having an opening therein;
a flexible lid sized to be disposed in the opening in the base, wherein one end of the lid is connected to the base by a pivotal connection;
a clasp connected with another end of the clasp configured to engage the base;
an emitter coupled to the lid; and
a detector coupled to the lid.
14. The sensor of claim 13 comprising an adhesive layer disposed on a first side of the base, the adhesive layer configured to adhere to a tissue location on a patient.
15. The sensor of claim 13 comprising a plurality of stacked independent adhesive layers disposed on a first tide of the base, the adhesive layers configured to adhere to a tissue location on a patient.
16. The sensor of claim 13 wherein the sensor is configured having at least a first position and a second position,
wherein in the first position the clasp engages the base, and the lid and the base together form a substantially flat sensor, and
wherein in the second position, the clasp is disengaged from the base and the lid is pivotally lifted from a tissue location on a patient.
17. The sensor of claim 13 wherein the sensor comprises an oximeter sensor.
18. A sensor comprising:
a base having an opening therein;
a lid sized to be disposed in the opening i the base, wherein one end of the lid is connected to the base by a pivotal conection;
a clasp connected with another end of the lid, the clasp configured to engage the base;
an emitter coupled to the lid;
a first lens coupled to the emitter;
a detector coupled to the lid; and
a second lens coupled to the detector, wherein the first lens and the second lens protrude beyond a patient contact side of the base when the lid is disposed in the opening in the base.
19. The sensor of claim 18 wherein the first lens is coupled to the emitter and the second lens is coupled to the sensor using an adhesive.
20. The sensor of claim 18 comprising an adhesive layer disposed on a first side of the base, the adhesive layer configured to adhere to a tissue location on a patient.
21. The sensor of claim 18 comprising a plurality of stacked independent adhesive layers disposed on a first side of the base, the adhesive layers configured to adhere to a tissue location on a patient.
22. The sensor of claim 18 wherein the sensor is configured having at least a first position and a second position,
wherein in the first position the clasp engages the base, and the lid and the base together form a substantially flat sensor, and
wherein in the second position, the clasp is disengaged from the base and the lid is pivotally lifted from a tissue location on a patient.
23. The sensor of claim 18 wherein the sensor comprises an oximeter sensor.
