Abstract

The present invention relates to a method and apparatus for improving the durability of a sensor, specifically one attached by an adhesive material to a subject. Specifically, the present invention discloses a method and apparatus for laminating a sensor and inserting the sensor into a protective shield for use. The shield includes some adhesive material to affix the sensor to the subject. A dirty, damaged, or worn out shield may be discarded and the sensor inserted into a new shield for continued use of the sensor.

Claims

1. A method for improving the durability of an otherwise disposable sensor, wherein said disposable sensor includes at least one light emitting diode, at least one photocell detector, and an attached first adhesive material, said method comprising the steps of:

a) modifying the disposable sensor to conform to a uniform size wherein said modifying includes removing said first adhesive material;

b) providing a laminating material of the appropriate shape for its intended use;

c) creating a first aperture in said laminating material which is at least as large as the size of said diode;

d) creating a second aperture in said laminating material which is at least as large as the size of said detector;

e) laminating said disposable sensor with said laminating material such that said first aperture is positioned homologously with said diode and wherein said second aperture is positioned homologously with said detector;

f) inserting said disposable sensor into a sleeve

g) providing a second adhesive material of the appropriate shape for attachment to a subject'"'"'s finger; and

h) coupling said adhesive material to said sleeve.

2. The method of claim 1 wherein said laminating material comprises a clear wrap.

3. The method of claim 1 wherein said laminating material includes a tape seal at each end.

4. The method of claim 1 wherein said second adhesive material comprises a clear moisture vapor transmission tape.

5. The method of claim 1 wherein said sleeve is comprised of polyethylene plastic.

6. The method of claim 1 wherein said second adhesive material includes a tab to facilitate said insertion of said disposable sensor in said sleeve.
