Abstract

Pulse oximeter apparatus and method comprising a reusable pulse oximeter probe and a disposable bandage. The bandage has receptacles for receiving and aligning the oximeter'"'"'s light emitting diode and photocell detector.

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 incorporated into plastic housings, one housing having an aperture or radiation transparent window aligned with said emitter and the other housing having an aperture or radiation transparent window aligned with said detector;

b) at least one bandage strip having adhesive on at least a portion of at least one face thereof and at least two receptacles mounted thereon, each receptacle having at least one aperture or radiation transparent window located therein;

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

2. The reusable pulse oximeter sensor and disposable bandage apparatus of claim 1 wherein said reusable pulse oximeter probe housings are made from a material selected from plastic, rubber, metal, wood, or other composite material.

3. The reusable pulse oximeter sensor and disposable bandage apparatus of claim 1 wherein said bandage receptacles are made from a material selected from plastic, rubber, metal, wood, or other composite material.

4. The reusable pulse oximeter sensor and disposable bandage of claim 1 wherein translucent silicone or other radiation transparent windows are sandwiched between said adhesive strip and said receptacles attached thereto.

5. The reusable pulse oximeter sensor and disposable bandage of claim 1 wherein said housings have tubular protrusions 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.

6. The reusable pulse oximeter sensor and disposable bandage of claim 1 wherein said bandage apparatus may be discarded after single patient use and said reusable probe may be used again on another patient in conjunction with a new bandage apparatus.

7. 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.

8. 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.

9. 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.

10. The reusable pulse oximeter sensor and disposable bandage of claim 9 wherein the housings and receptacles have recessed areas for adhesion of the “

mushroom hook”

hook and loop material.

11. The reusable pulse oximeter sensor and disposable bandage of claim 9 wherein the receptacles of said disposable bandage are the “

mushroom hook”

material itself.

12. The reusable pulse oximeter probe and disposable bandage of claim 1 including attachment means for securing said probe housings to said bandage receptacle comprising a “

ring and groove”

snap-on type connector.

13. The reusable pulse oximeter probe and disposable bandage of claim 1 including attachment means for securing said probe housings to said bandage receptacles comprising a “

twist and lock”

type connector.

14. The reusable pulse oximeter probe and disposable bandage of claim 1 wherein the attachment means for securing said probe housings to said bandage receptacles comprises a “

threaded flange”

type connector.

15. The reusable pulse oximeter probe and disposable bandage of claim 1 including a locking mechanism comprising at least one notch, slot, or indentation in at least one of said bandage receptacles, for matedly engaging a locking lever or tab of at least one of said pulse oximeter probe housings.

16. The reusable pulse oximeter probe and disposable bandage of claim 1 including a locking mechanism comprising at least one tab or lever on at least one of said receptacles, for matedly engaging a slot or indentation in at least one of said pulse oximeter probe housings.

17. The reusable pulse oximeter probe and disposable bandage of claim 15 wherein said bandage incorporates a foam strip or strips for patient comfort.
