Abstract

Embodiments of the present invention relate to a pulse oximetry sensor. The pulse oximetry sensor may comprise an emitter configured to transmit a signal into tissue, a detector configured to detect the signal, and a quality assurance component coupled to a first sensor component and second sensor component. The quality assurance component may be configured to break and disable the sensor upon separation of the first sensor component from the second sensor component.

Claims

1. A pulse oximetry sensor, comprising:

an emitter configured to transmit a signal into tissue;

a detector configured to detect the signal; and

a quality assurance component coupled to a first sensor component and second sensor component, the quality assurance component configured to break and disable the sensor upon separation of the first sensor component from the second sensor component, wherein the quality assurance component is interwoven with the first sensor component and the second sensor component.

2. The sensor of claim 1, wherein the quality assurance component comprises a trace.

3. The sensor of claim 1, wherein the quality assurance component comprises an information element.

4. The sensor of claim 1, wherein the quality assurance component comprises a memory.

5. The sensor of claim 1, wherein the quality assurance component comprises a resistor.

6. The sensor of claim 1, wherein the quality assurance component comprises a communication component configured to provide electrical communication with a monitor.

7. The sensor of claim 1, wherein the first and second sensor components are first and second sensor layers and the quality assurance component is disposed across the first and second layers.

8. The sensor of claim 1, wherein a portion of the quality assurance component couples to the second sensor component at an exposed location on the first sensor component, the exposed location defining an electrical breakpoint.

9. The sensor of claim 1, wherein the first and second sensor components are first and second sensor layers and the quality assurance component is interwoven with the first and second layers.

10. A method of assured quality operation of a pulse oximetry sensor, comprising:

disabling the pulse oximetry sensor upon separation of a first sensor component and a second sensor component by breaking a quality assurance component that is interwoven with the first and second sensor components.

11. The method of claim 10, wherein breaking the quality assurance component comprises breaking a conductive trace to disable the pulse oximetry sensor.

12. The method of claim 10, wherein breaking the quality assurance component comprises breaking an information element to disable the pulse oximetry sensor.

13. The method of claim 10, wherein breaking the quality assurance component comprises breaking a memory to disable the pulse oximetry sensor.

14. The method of claim 10, wherein breaking the quality assurance component comprises breaking a resistor to disable the pulse oximetry sensor.

15. The method of claim 10, comprising breaking the quality assurance component proximate an electrical break point.

16. The method of claim 15, wherein breaking the quality assurance component proximate the electrical break point comprises breaking the quality assurance component proximate a junction between the first and second sensor components.

17. A method of manufacturing a quality assured pulse oximetry sensor, comprising:

providing an emitter configured to transmit a signal into tissue;

providing a detector configured to detect the signal; and

providing a quality assurance component interwoven with a first sensor component and second sensor component, the quality assurance component configured to break and disable the sensor upon separation of the first sensor component from the second sensor component.

18. The method of claim 17, wherein the quality assurance component comprises a trace.

19. The method of claim 17, wherein the quality assurance component comprises an information element.

20. The method of claim 17, comprising disposing the quality assurance component across a junction between the first and second sensor components.

21. The method of claim 17, comprising coupling a portion of the quality assurance component to the second sensor component at an exposed location on the first sensor component, the exposed location defining an electrical breakpoint.
