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

securing at least two support rings to one side of a piece of window film;

securing a photodiode within one of the support rings;

securing an LED assembly within the other of the support rings;

adhesively securing a back film mounting member to a portion of a foam wrap member; and

adhesively securing a portion of the window film to a portion of the back film mounting member.

2. The method of claim 1, wherein the method includes the step of:

securing a top liner to the other side of the window film.

3. The method of claim 1, wherein the method includes the step of:

attaching a portion of a cable to the photodiode; and

attaching another portion of the cable to the LED assembly.

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

providing a foam wrap member;

providing a photodiode on the foam wrap member;

providing an LED assembly on the foam wrap member;

adhesively securing a window film to the foam wrap member covering the LED assembly and the photodiode on the foam wrap member.

5. The method of claim 4, wherein the method includes the step of:

securing a top liner to a side of the window film.

6. The method of claim 4, wherein the method includes the step of:

attaching a portion of a cable to the photodiode; and

attaching another portion of the cable to the LED assembly.
