Abstract

A medical sensor that allows wrapping about an applied part while maintaining the alignment of the detector and emitter is provided. The medical sensor includes a carrier band that can accommodate variably sized applied parts without misaligning the detector and emitter. The medical sensor can provide space between the skin of the applied part and the emitter and detector. The medical sensor carrier band can be designed with a flexible region and thicker mounting sections that act as spring-loaded mounts when the carrier band is secured in a wrapped position.

Claims

1. A medical sensor comprising:

a foam carrier band;

a detector mounted on a portion of the carrier band; and

an emitter mounted on a portion of the carrier band,

wherein said carrier band is formed to accommodate variably sized applied parts, while maintaining substantial alignment of the detector and the emitter when applied to an applied part.

2. The medical sensor of claim 1, wherein said carrier band is polyethylene.

3. The medical sensor of claim 1, wherein said carrier band comprises a thin, flexible groove section, a thick detector mounting section, and a thick emitter mounting section.

4. The medical sensor of claim 1, wherein said carrier band comprises an emitter window, wherein said emitter window provides an air gap between the emitter and the skin of the applied part.

5. The medical sensor of claim 4, wherein said emitter window comprises a cut out region of the carrier band and a layer of material on either side of the carrier band covering the cut out region, wherein said air gap is located between the material layers.

6. The medical sensor of claim 1 further comprising a means for securing the medical sensor in a wrapped position.

7. The medical sensor of claim 1 further comprising a detector window, wherein said detector window provides space between the detector and the skin of the applied part.

8. The medical sensor of claim 1, wherein the medical sensor is a pulse oximetry sensor.

9. A medical sensor comprising:

a carrier band;

a detector mounted on a portion of the carrier band; and

an emitter mounted on a recessed portion of the carrier band,

wherein when the medical sensor is in a wrapped position around an applied part, the recessed portion of the carrier band creates an air gap between the emitter and the skin of the applied part.

10. The medical sensor of claim 9, wherein the air gap between the emitter and the skin of the applied part is a predetermined distance.

11. The medical sensor of claim 9, wherein said carrier band is polyethylene foam.

12. The medical sensor of claim 9, wherein said carrier band comprises a thin, flexible groove section, a thick detector mounting section, and a thick emitter mounting section.

13. The medical sensor of claim 9, wherein said recessed portion comprises a cut out region of the carrier band and a layer of material on either side of the carrier band covering the cut out region, wherein said air gap is located between the material layers.

14. The medical sensor of claim 9, wherein the medical sensor is a pulse oximetry sensor.

15. A medical sensor comprising:

a carrier band including a thin section that facilitates wrapping of the carrier band and one or more thick sections that act as spring-loaded mounts when the carrier band is secured in a wrapped position;

a detector mounted to a portion of said carrier band; and

an emitter mounted to a portion of said carrier band.

16. The medical sensor of claim 15, wherein said detector and said emitter are substantially aligned when said carrier band is in the wrapped position.

17. The medical sensor of claim 15, wherein said carrier band is polyethylene foam.

18. The medical sensor of claim 15 further comprising an emitter window, wherein said emitter window comprises a cut out region of the carrier band and a layer of material on either side of the carrier band covering the cut out region, wherein said air gap is located between the material layers.

19. The medical sensor of claim 15, wherein the air gap between the emitter and the skin of the applied part is a predetermined distance.

20. The medical sensor of claim 15, wherein the medical sensor is a pulse oximetry sensor.
