Abstract

Sensor designs or shapes to facilitate the placement of sensors on a patient are provided. For example, a first sensor may include a sensor body having a keyed interface region that is configured to align with a complementary keyed interface region of second sensor. Such sensors may also include various features to further facilitate the positioning of the sensors on the patient tissue and the positioning of the sensors with respect to one another. For example, the first sensor may include indicia relating to the second sensor having the complementary keyed interface region.

Claims

1. A sensor, comprising:

one or more sensing components configured to generate a physiological signal of a patient; and

a sensor body configured to house the one or more sensing components, wherein the sensor body comprises a keyed interface region, and wherein the keyed interface region is configured to align with a complementary keyed interface region of a second sensor.

2. The sensor of claim 1, wherein the sensor comprises a pulse oximetry sensor or a regional oximetry sensor.

3. The sensor of claim 1, wherein the sensor comprises an electroencephalography sensor.

4. The sensor of claim 1, wherein the sensor body is configured to be applied to the patient'"'"'s forehead.

5. The sensor of claim 1, wherein the keyed interface region comprises at least one of a protrusion or a cutout complementing a second cutout or a second protrusion, respectively, of the second sensor.

6. The sensor of claim 1, wherein the sensor body comprises one or more indicia to facilitate proper placement of the sensor on the patient.

7. The sensor of claim 6, wherein the one or more indicia comprise one or more markings indicating the proper placement of the sensor on the patient relative to an anatomical feature of the patient.

8. The sensor of claim 6, wherein the one or more indicia comprise a label identifying the second sensor and at least one arrow pointing toward the second sensor when the keyed interface region of the sensor and the complementary keyed interface region of the second sensor are aligned, and wherein the label and the at least one arrow are located on the sensor body proximate to the keyed interface region.

9. The sensor of claim 6, wherein the one or more indicia comprise a label identifying an anatomical feature of the patient and at least one arrow pointing toward the anatomical feature of the patient when the sensor body is applied to the patient.

10. A system, comprising:

a first sensor configured to generate a first physiological signal of a patient, wherein the first sensor comprises a first sensor body comprising a first keyed interface region;

a second sensor configured to generate a second physiological signal of the patient, wherein the second sensor comprises a second sensor body comprising a second keyed interface region; and

wherein the first keyed interface region is complementary to the second keyed interface region such that the first and the second keyed interface regions are configured to align when the first and the second keyed interface regions are placed alongside one another.

11. The system of claim 10, wherein the first sensor body comprises a first label identifying the second sensor and at least one arrow pointing toward the second sensor when the first and second keyed interface regions are aligned, and wherein the first label and the at least one arrow are located on the first sensor body proximate to the first keyed interface region.

12. The system of claim 10, comprising a third sensor configured to generate a third physiological signal of the patient, wherein the third sensor comprises a third sensor body comprising a third keyed interface region, and wherein the first sensor body, the second sensor body, or a combination thereof comprise a fourth keyed interface region complementary to the third keyed interface region.

13. The system of claim 12, wherein the first and second keyed interface regions comprise a first color or a first pattern of markings, and wherein the third and fourth keyed interface regions comprise a second color or a second pattern of markings.

14. The system of claim 10, wherein at least one of the first sensor body and the second sensor body comprise a label identifying an anatomical feature of the patient and at least one marking identifying a preferred placement of the first or second sensor relative to the anatomical feature when the first or the second sensor body is applied to the patient.

15. The system of claim 10, comprising a patient monitor communicatively coupled to the first sensor and comprising a processor configured to calculate a first physiological parameter of the patient based at least in part upon the first physiological signal, wherein the first sensor comprises a pulse oximetry sensor.

16. The system of claim 15, wherein the patient monitor is communicatively coupled to the second sensor and the processor is configured to calculate a second physiological parameter of the patient based at least in part upon the second physiological signal, wherein the second sensor comprises a regional oximetry sensor.

17. The system of claim 10, comprising an electroencephalography monitor communicatively coupled to the first sensor and configured to calculate a physiological parameter of the patient based at least in part upon the first physiological signal, wherein the first sensor comprises a bispectral index sensor.

18. A medical sensor kit, comprising:
