Abstract

A reusable pulse oximeter sensor and disposable bandage apparatus includes: a) a reusable pulse oximeter probe assembly with at least one light-emitting diode and one photocell detector wherein the detector and emitter are enclosed in plastic housings one housing having an aperture or radiation transparent window aligned with the emitter and the other housing having an aperture or radiation transparent window aligned with the detector; and b) a bandage strip having adhesive on at least a portion of at least one face thereof and at least two plastic receptacles mounted thereon, each receptacle having at least one aperture or radiation transparent window located therein; wherein the probe housings can matedly engage the bandage receptacles, and transmit and receive light through the apertures or radiation transparent windows of the mated housings and receptacles, and through the appendage of a patient.

Claims

1. A disposable bandage apparatus for use with a reusable pulse oximeter sensor assembly having at least one light-emitting diode and one photocell detector wherein said detector and emitter are each enclosed in a male probe housing, respectively, one probe housing having an aperture or radiation transparent window aligned with said emitter and a second one of said probe housings having a radiation transparent window aligned with said detector, said bandage apparatus comprising a bandage strip having adhesive on at least a portion of at least one face thereof and two plastic female receptacles spacedly mounted thereon, each receptacle having at least one radiation transparent window located therein;

wherein said male probe housings can matedly engage said female receptacles, and transmit and receive light through the apertures or radiation transparent windows of said housings and receptacles when mated, and through the appendage of a patient.

2. The disposable bandage apparatus of claim 1 wherein translucent silicone radiation transparent windows are sandwiched between said bandage strip and said receptacles attached thereto.

3. The disposable bandage apparatus of claim 1 wherein said female receptacles have a concave shape on one side thereof in order to seat conformably on a human digit.

4. The disposable bandage apparatus 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.

5. The disposable bandage apparatus 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.

6. The disposable bandage apparatus of claim 5 wherein the housings and receptacles have recessed areas for adhesion of the “

mushroom hook”

hook and loop material.

7. The disposable bandage apparatus of claim 5 wherein the receptacles of said disposable bandage are the “

mushroom hook”

material itself.

8. The disposable bandage apparatus of claim 1 wherein the receptacles mounted thereon can matedly engage modular housings with locking levers, said receptacles having a notch, slot or indentation therein whereby at least a portion of said locking levers can lodge therein, thus locking and securing said housings to said receptacles.

9. The bandage apparatus of claim 1 wherein at least a portion of said plastic receptacles themselves constitute said radiation transparent windows.

10. A disposable oximeter mounting strip for use in oximetry, said mounting strip having first and second sides and a pair of radiation transparent windows, adhesive on said first side for attachment to an appendage of a patient, a removable backing strip adhered to said adhesive and a pair of modular female receptacle sockets mounted, in respective alignment with said pair of windows, on said second side for matedly and removably engaging a reusable modular pulse oximeter probe emitting diode and a reusable pulse oximeter probe photocell detector, respectively.

11. The mounting strip of claim 10 wherein each of said modular female receptacle sockets incorporates a locking lever for removably engaging said modular reusable pulse oximeter probe light emitting diode and photocell detector, respectively.

12. A method for the affixation of a reusable pulse oximeter sensor to the digit of a patient, comprising, providing a planar adhesive strip with at least two apertures therein, and two plastic receptacles mounted on top of said apertures, respectively, visually aligning on said digit of a patient by looking through a first of said apertures in order to position said first aperture over the nail bed of said patient'"'"'s digit, then affixing said adhesive strip on the patient'"'"'s digit prior to the engagement of the reusable probe in said plastic receptacles.

13. A disposable bandage apparatus for use with a reusable pulse oximeter sensor assembly having at least one light-emitting diode and at least one photocell detector wherein said detector and emitter are enclosed in, or mounted to, probe housings, one of said probe housings having at least one aperture or radiation transparent window aligned with said emitter and a second one of said probe housings having at least one aperture or radiation transparent window aligned with said detector, said bandage apparatus comprising at least one bandage strip having adhesive on at least a portion of at least one face thereof, and at least two plastic receptacles mounted thereon, each receptacle having at least one radiation transparent window located therein;

wherein each of said probe housings can matedly engage at least one of said receptacles, and transmit and receive light through the apertures or radiation transparent windows of said housings and receptacles when mated, and through the appendage of a patient.

14. The disposable bandage apparatus of claim 13 wherein said receptacles have a concave shape on one side thereof in order to seat conformably on a human digit.

15. At least one disposable mounting strip for use in oximetry, said at least one mounting strip having first and second sides, and at least two radiation transparent windows located therein, adhesive on at least a portion of said first side for attachment to the appendage of a patient, at least one removable backing strip adhered to at least a portion of said adhesive, and at least two receptacles mounted on said second side, and in respective alignment with said at least two windows, said receptacles for matedly and removably engaging a reusable pulse oximeter probe light-emitting diode and a reusable pulse oximeter probe photocell detector respectively.
