Abstract

An oximetry sensor comprising a wrap member including a fastener and adhesive member and an LED assembly and photodiode connected to a cable.

Claims

1. An oximetry sensor comprising:

a wrap member having a plurality of apertures therein, the wrap member including a compliant foam substrate and a fabric cover secured to at least a portion of the compliant foam substrate and extending over one side of the compliant foam substrate, wherein said plurality of apertures extend through said compliant foam substrate and said fabric cover, including a fastener secured to one end thereof, the fastener having a portion thereof engagable with a portion of the fabric cover of the wrap member, and including an adhesive member secured to another side of the compliant foam substrate and surrounding the plurality of apertures;

an LED assembly having a portion thereof engaging an aperture of the plurality of apertures in the wrap member; and

a photodiode having a portion thereof engaging another aperture of the plurality of apertures.

2. The oximetry sensor of claim 1, wherein the adhesive member secured to the compliant foam substrate is adhesively secured thereto.

3. The oximetry sensor of claim 1, wherein the adhesive member secured to the wrap member is an annular shaped member.

4. The oximetry sensor of claim 1, wherein the adhesive member secured to the wrap member comprises a generally rectangular shaped member secured to the wrap member.

5. The oximetry sensor of claim 1, wherein the adhesive member secured to the wrap member includes a release liner thereover.

6. The oximetry sensor of claim 5, wherein the adhesive member secured to the wrap member includes a double sided adhesively coated member.

7. The oximetry sensor of claim 1, wherein the compliant foam substrate includes one of a polyester foam and a plastic foam substrate.

8. The oximetry sensor of claim 1, wherein the compliant foam substrate includes one of a polyester foam, a plastic foam, and a compliant foam substrate and the fabric cover comprises a cloth member.

9. The oximetry sensor of claim 1, further comprising:

a cable connected to the LED assembly and the photodiode.

10. The oximetry sensor of claim 1, wherein fabric cover comprises a cloth member.

11. The oximetry sensor of claim 10, wherein the fastener of the wrap member includes a plurality of hooks thereon to engage the fabric cover of the wrap member.

12. The oximetry sensor of claim 11, wherein the fabric cover of the wrap member includes a plurality of loops therein to engage the plurality of hooks located on the fastener.

13. The oximetry sensor of claim 1, wherein the LED assembly and the photodiode are connected to a cable having a connector on one end thereof.

14. The oximetry sensor of claim 1, wherein the LED assembly and the photodiode each include a housing, each housing including an integral upper flange and an integral lower flange.

15. The oximetry sensor of claim 14, wherein the housing includes a cover therefore, the cover being transparent to infrared light.

16. A method of making an oximetry sensor, wherein the method comprises the steps of:

providing an LED assembly having a housing including two flanges thereon;

providing a photodiode having a housing including two flanges thereon;

providing a wrap member having a cloth cover, the wrap member including a compliant foam substrate, the cloth cover secured to at least a portion of the foam substrate and extending over one side of the compliant foam substrate, including a fastener secured to one end of the wrap member, the fastener having a portion thereof engageable with a portion of the cloth cover of the wrap member, an adhesive member secured to the wrap member having a removable liner cover thereover, and a plurality of apertures extending through the compliant foam substrate, the cloth cover, the adhesive member, and the removable liner cover of the wrap member;

inserting the photodiode within one of the plurality of apertures in the wrap member; and

inserting the LED assembly within another aperture in the wrap member.

17. The method of claim 16, wherein the method includes the step of:

providing a cable;

attaching a portion of a cable to the photodiode; and

attaching another portion of a cable to the LED assembly.

18. An oximetry sensor comprising:

a wrap member having a cloth cover, the wrap member including a compliant foam substrate, the cloth cover secured to at least a portion of the foam substrate and extending over one side of the compliant foam substrate, a fastener secured to one end of the wrap member, the fastener having a portion thereof engageable with a portion of the cloth cover of the wrap member, a plurality of apertures extending through the compliant foam substrate and the cloth cover, and an adhesive member surrounding the plurality of apertures; and

a LED assembly and a photodiode, each secured in an aperture of the plurality of apertures in the wrap member.

19. The oximetry sensor of claim 18, wherein the compliant foam substrate comprises one of polyester foam and plastic foam.

20. The oximetry sensor of claim 19, wherein the fastener of the wrap member includes a plurality of hooks thereon to engage the cloth cover portion of the wrap member.

21. The oximetry sensor of claim 20, wherein the cloth cover portion of the wrap member includes a plurality of loops therein to engage the plurality of hooks located on the fastener.

22. The oximetry sensor of claim 20, wherein the adhesive member secured to the wrap member is adhesively secured thereto.

23. The oximetry sensor of claim 20, wherein the adhesive member secured to the wrap member comprises a generally rectangular shaped member secured to the wrap member.

24. The oximetry sensor of claim 20, wherein the adhesive member secured to the wrap member comprises a generally elongated in shape member secured to the wrap member.

25. The oximetry sensor of claim 20, wherein the adhesive member secured to the wrap member is annular in shape.

26. The oximetry sensor of claim 25, wherein the adhesive member secured to the wrap member includes a double sided adhesively coated member.

27. The oximetry sensor of claim 25, wherein the adhesive member secured to the wrap member includes an adhesive member having one side thereof adhesively coated.

28. The oximetry sensor of claim 20, wherein the adhesive member secured to the wrap member includes a release liner thereover.

29. The oximetry sensor of claim 20, wherein the adhesive member secured to the wrap member includes a member of silicon elastomer.
