Abstract

A reusable pulse oximeter and disposable bandage apparatus and method which includes a reusable oximeter probe assembly with at least one light emitting diode, one photocell detector, each of which is enclosed in first and second plastic housings, respectively. A generally planar bandage strip having adhesive on at least a portion of at least one face thereof and at least two plastic receptacles attached to the other face thereof, each receptacle having an aperture and being adapted to matedly receive the first and second housings of the reusable pulse oximeter probe, respectively. In use the apertures are aligned on the digit of a patient by looking through the aperture in order to attach a first aperture over the nail bed of a patient and, subsequently, engaging the reusable probe components in the receptacles.

Claims

1. A reusable pulse oximeter sensor and disposable bandage apparatus, comprising:

a) a reusable pulse oximeter probe assembly with at least one light emitting diode and one photocell detector wherein said detector and emitter are enclosed in plastic housings, a first of said housings having an aperture aligned with said emitter and a second of said housings having an aperture aligned with said detector;

b) a generally planar bandage strip having adhesive on at least a portion of at least one face thereof and at least two plastic receptacles attached to the other face thereof, each receptacle having at least one aperture located therein;

wherein said first and second housings can matedly engage said bandage receptacles, and transmit and receive light through the apertures of said housings and receptacles, and through the appendage of a patient.

2. The reusable pulse oximeter sensor and disposable bandage of claim 1 wherein translucent silicone windows are sandwiched between said adhesive strip, and said receptacles attached thereto.

3. The reusable pulse oximeter sensor and disposable bandage of claim 1 wherein there are tubular protrusions on said housing and the apertures of said receptacles are large enough to accept the tubular protrusions of said housings for the purpose of concentric location of the housings to the receptacles and the proper transmission of light therethrough.

4. The reusable pulse oximeter sensor and disposable bandage of claim 1 wherein said bandage apparatus is constructed of inexpensive materials such that it may be discarded after single patient use and said reusable pulse oximeter probe may be used again on another patient in conjunction with a new planar bandage strip.

5. The reusable pulse oximeter sensor and disposable bandage of claim 1 wherein said receptacles have a concave shape on one side thereof in order to seat conformably on a human digit.

6. The reusable pulse oximeter sensor and disposable bandage of claim 1 wherein said receptacles have a flat surface on at least one side thereof in order to seat conformably on a human ear, nose, or foot.

7. The reusable pulse oximeter sensor and disposable bandage of claim 1 wherein the housings and receptacles contain "mushroom hook" type hook and loop material for the purpose of adhering and detaching said housings to and from said receptacles.

8. The reusable pulse oximeter sensor and disposable bandage of claim 7 wherein the housings and receptacles have recessed areas for adhesion of the "mushroom hook" hook and loop material.

9. The reusable pulse oximeter sensor and bandage of claim 1 wherein the receptacles of said disposable bandage are the "mushroom hook" material itself.

10. A method for improving the affixation of a reusable pulse oximeter sensor probe to a patient comprising, providing a planar adhesive strip with at least two apertures therein, and plastic receptacles mounted on top of said apertures and reusable probe components receivable in said receptacles, visually aligning said strip on the digit of a patient by looking through said first aperture in order to attach said first aperture over the nail bed of a patient, and then engaging the reusable probe components in said receptacles.
