Abstract

A sensor cable is provided that includes a sensor point of attachment configured to attach to a spectrophotometric sensor, and a connector configured to attach to a patient monitor. The sensor cable includes a coiled portion between the sensor point of attachment and the monitor connector. A sensor assembly and system including such a cable are also provided.

Claims

1. A sensor assembly, comprising:

a sensor body of a spectrophotometric sensor; and

a sensor cable comprising a coiled portion.

2. The sensor assembly of claim 1, wherein the sensor body comprises an overmolded coating.

3. The sensor assembly of claim 1, wherein the sensor body comprises one or more light emitting diodes and a photodetector.

4. The sensor assembly of claim 1, wherein the sensor assembly comprises at least one of a pulse oximetry sensor, a sensor for measuring a water fraction, or a combination thereof.

5. The sensor assembly of claim 1, wherein the coiled portion is approximately 2 inches long or greater.

6. The sensor assembly of claim 1, wherein the coiled portion is approximately one-quarter of the length of the sensor cable.

7. The sensor assembly of claim 1, wherein the coiled portion is approximately one-half of the length of the sensor cable.

8. The sensor assembly of claim 1, wherein the coiled portion is substantially all of the length of the sensor cable.

9. The sensor assembly of claim 1, wherein the coiled portion allows rotation of one end of the cable without rotational tension at the other end.

10. The sensor assembly of claim 1, wherein the coiled portion absorbs longitudinal tension to reduce longitudinal tension at one or both ends.

14. The sensor assembly of claim 11, wherein the sensor assembly comprises at least one of a pulse oximetry sensor, a sensor for measuring a water fraction, or a combination thereof.

11. A monitoring system, comprising:

a monitor;

a sensor assembly adapted to be coupled to the monitor, the sensor assembly comprising;

a sensor body of a spectrophotometric sensor; and

a sensor cable comprising a coiled portion.

12. The sensor assembly of claim 11, wherein the sensor body comprises an overmolded coating.

13. The sensor assembly of claim 11, wherein the sensor body comprises one or more light emitting diodes and a photodetector

15. A method of connecting a sensor assembly to a monitor, comprising:

placing a sensor assembly on a location on the body of a patient; and

connecting the sensor assembly to a monitor using a sensor cable comprising a coiled portion.

17. The sensor assembly of claim 15, wherein the sensor assembly comprises one or more light emitting diodes and a photodetector

18. The sensor assembly of claim 15, wherein the sensor assembly comprises at least one of a pulse oximetry sensor, a sensor for measuring a water fraction, or a combination thereof.

16. The method of 15, wherein the sensor assembly comprises a sensor body having an overmolded coating.

19. A sensor cable, comprising:

a point of attachment configured to attach to a spectrophotometric sensor;

a connector configured to attach to a patient monitor; and

a coiled portion disposed between the point of attachment and the connector.

20. The sensor assembly of claim 19, wherein the coiled portion is approximately 2 inches long or greater.

21. The sensor assembly of claim 19, wherein the coiled portion is approximately one-quarter of the length of the sensor cable.

22. The sensor assembly of claim 19, wherein the coiled portion is approximately one-half of the length of the sensor cable.

23. The sensor assembly of claim 19, wherein the coiled portion is substantially all of the length of the sensor cable.

24. The sensor assembly of claim 19, wherein the coiled portion allows rotation of one end of the cable without rotational tension at the other end.

25. The sensor assembly of claim 19, wherein the coiled portion absorbs longitudinal tension to reduce longitudinal tension at one or both ends.
