Abstract

A sensor cover according to embodiments of the disclosure is capable of being used with a non-invasive physiological sensor, such as a pulse oximetry sensor. Certain embodiments of the sensor cover reduce or eliminate false readings from the sensor when the sensor is not in use, for example, by blocking a light detecting component of a pulse oximeter sensor when the pulse oximeter sensor is active but not in use. Further, embodiments of the sensor cover can prevent damage to the sensor. Additionally, embodiments of the sensor cover prevent contamination of the sensor.

Claims

1-4. -4. (canceled)

5. A method of blocking readings by a noninvasive optical physiological sensor, the method comprising:

providing a sensor cover comprising;

an opaque portion attachable to the sensor and configured to block readings by the sensor; and

a portion that protrudes from the sensor to facilitate removal of the sensor cover; and

attaching the sensor cover to the sensor, the sensor cover blocking readings by the sensor and removable from the sensor,

wherein the sensor comprises;

a light source configured to emit light from one or more emitters of the sensor; and

a detector configured to receive at least a portion of the light emitted by the one or more emitters after the light has passed through a tissue site.

6. The method of claim 5, wherein the portion that protrudes from the sensor comprises an elongate portion that extends past the sensor.

7. The method of claim 5, wherein the sensor is an adhesive sensor having a flexible substrate and an adhesive layer.

8. The method of claim 7, wherein at least the opaque portion comprises an adhesive cover attachable to the adhesive layer of the sensor.

9. The method of claim 5, wherein the sensor cover further comprises an adhesive layer on the opaque portion, the adhesive layer configured to removably attach over a sensing portion of the sensor.

10. The method of claim 5, further comprising:

activating the light source of the sensor to emit light from the one or more emitters of the sensor; and

blocking, with the sensor cover, the light from the one or more emitters from being received by the detector of the sensor.

11. The method of claim 5, wherein the opaque portion is attachable over at least one of the detector or the one or more emitters.

12. The method of claim 5, wherein the opaque portion is configured to block ambient light from a surrounding area.

13. The method of claim 5, wherein the sensor is a pulse oximeter sensor.

14. A sensor cover for use with a noninvasive optical physiological sensor, the sensor cover comprising:

an opaque portion attachable to the sensor and configured to block optical readings by the sensor; and

a portion that protrudes from the sensor to facilitate removal of the sensor cover,

wherein the sensor comprises;

a light source configured to emit light from one or more emitters of the sensor; and

a detector configured to receive at least a portion of the light emitted by the one or more emitters after the light has passed through a tissue site.

15. The sensor cover of claim 14, wherein the portion that protrudes from the sensor comprises an elongate portion that extends past the sensor.

16. The sensor cover of claim 14, wherein the sensor is an adhesive sensor having a flexible substrate and an adhesive layer.

17. The sensor cover of claim 16, wherein at least the opaque portion comprises an adhesive cover attachable to the adhesive layer of the sensor.

18. The sensor cover of claim 14, further comprising:

an adhesive layer on the opaque portion, the adhesive layer configured to removably attach over a sensing portion of the sensor.

19. The sensor cover of claim 14, wherein the sensor cover is configured to block the light from the one or more emitters from being received by the detector.

20. The sensor cover of claim 14, wherein the opaque portion is attachable over at least one of the detector or the one or more emitters.

21. The sensor cover of claim 14, wherein the opaque portion is configured to block ambient light from a surrounding area.

22. The method of claim 14, wherein the sensor is a pulse oximeter sensor.
