Abstract

An oximetry sensor comprising a foam wrap member including a fastener, back film mounting member, LED assembly and photodiode connected to a cable, support rings for the LED assembly and photodiode, window film for the LED assembly and photodiode, and a top liner.

Claims

1. An oximetry sensor comprising:

an elongated foam wrap member including a fastener on one end thereof, the foam wrap member having a foam member having a first side, a second side, and a thickness, the foam member having a fabric member attached thereto on the first side of the foam member;

an LED assembly and a photodiode located on the second side of the foam member;

a window film attached to the other end of the second side of the foam member of the foam wrap member for covering the LED assembly and photodiode; and

a top liner attached to a portion of the window film and covering a portion of the window film.

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

a back film mounting member.

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

support rings for the LED assembly and the photodiode.

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

a cable connected to the LED assembly and the photodiode.

5. The oximetry sensor of claim 2, wherein the back film mounting member is

adhesively secured to a portion of the foam wrap member.

6. The oximetry sensor of claim 5, wherein the fastener of the foam wrap member includes a plurality of hooks thereon to engage the fabric member of the foam wrap member.

7. The oximetry sensor of claim 6, wherein the fabric member of the foam wrap member includes a plurality of loops therein to engage the plurality of hooks located on the fastener.

8. The oximetry sensor of claim 3, wherein the support rings are adhesively secured to a portion of the window film.

9. The oximetry sensor of claim 1, wherein the support rings are adhesively secured to a portion of the back film mounting member and the window film.

10. The oximetry sensor of claim 1, wherein the top liner is adhesively secured to a portion of the window film.

11. 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.

12. The oximetry sensor of claim 11, wherein the cable includes a connector on one end thereof.

13. The oximetry sensor of claim 1, wherein the support rings are adhesively secured to a portion of the back film mounting member and a portion of the window film.

14. An oximetry sensor comprising:

an elongated foam wrap member including a fastener secured thereto having a plurality of hooks thereon, the foam wrap member having a foam portion secured to a fabric portion, the fastener attached to one end of the elongated foam wrap member;

a back film mounting member attached to a portion of the foam wrap member adjacent the other end thereof, the back film mounting member attached to a side of the foam portion of the foam wrap member opposite the fabric portion of the foam wrap member;

an LED assembly and a photodiode, the LED assembly and the photodiode attached to a portion of the back film mounting member;

a window film covering the LED assembly and the photodiode, the window film secured to a portion of the back film mounting member; and

a top liner attached to a portion of the back film mounting member, the window film covered by the top liner.

15. The oximetry sensor of claim 14, wherein the back film mounting member is adhesively secured to a portion of the foam wrap member.

16. The oximetry sensor of claim 14, wherein the fastener of the foam wrap member includes a plurality of hooks thereon to engage the fabric portion of the foam wrap member.

17. The oximetry sensor of claim 16, wherein the fabric portion of the foam wrap member includes a plurality of loops therein to engage the plurality of hooks located on the fastener.

18. The oximetry sensor of claim 14, wherein support rings are adhesively secured to a portion of the window film.

19. The oximetry sensor of claim 14, wherein support rings are adhesively secured to a portion of the back film mounting member and the window film.

20. The oximetry sensor of claim 14, wherein the top liner is adhesively secured to a portion of the window film.

21. The oximetry sensor of claim 14, wherein the window film is transparent to red and infrared light.

22. An oximetry sensor comprising:

an elongated foam wrap member including a fastener having a plurality of hooks thereon, the foam wrap member having a foam portion having a first side and a second side, and having fabric members attached to the first side and the second side of the foam portion, and having the fastener attached to one end of the elongated foam wrap member;

an LED assembly and a photodiode located on the elongated foam wrap member; and

a top liner secured to a portion of the foam wrap member adjacent the other end thereof, the top liner securing the LED assembly and the photodiode in position on the foam wrap member.

23. An oximetry sensor comprising:

an elongated foam wrap member including a fastener having a plurality of hooks thereon, the foam wrap member having a foam portion enclosed by a fabric member, the fastener attached to one end of the elongated foam wrap member;

an LED assembly and a photodiode located on the elongated foam wrap member; and
