Abstract

A reusable pulse oximeter sensor and disposable liner, comprising (a) a reusable pulse oximeter probe assembly including at least one light emitting diode and one photocell detector wherein said detector and emitter are mounted in plastic finger clip housing arms; and (b) at least one disposable foam strip having an aperture or apertures therein; and wherein the foam strip or strips have plastic modular receptacle which can matedly and removably engage the fingerclip housing arms and transmit and receive light through the apertures in foam strip or strips and through the appendage of a patient.

Claims

1. In a spring clip oximeter probe having an emitter housing arm and a sensor housing arm which are biased towards each other at a predetermined pressure to grasp a portion of a living human body through which blood flows, an oximeter emitter mounted in said emitter housing arm to emit radiation into said portion of the living body and a radiation sensor mounted in said sensor housing arm for sensing radiation which passes through said portion of a living body, the improvement comprising a disposable safety shield detachably mounted on each of said housing arms, said safety shield having a radiation transparent window means isolating said emitter and sensor from said living body wherein each housing arm has a slot juxtaposed at the sides of said emitter and sensor, respectively, and said disposable shield having a slot engaging member at the respective ends thereof adapted to be received in said slot juxtaposed at the sides of said emitter and sensor, for receiving an end of said shield.

2. A disposable liner for use with a reusable pulse oximeter probe assembly including at least one light emitting diode and one photocell detector wherein said detector and emitter are mounted in plastic finger clip housing arms, said disposable liner comprising:

a disposable adhesive bandage including a disposable foam strip having a pair of apertures therein and modular receptacles carried on said foam strip, one over each aperture, respectively,

wherein said modular receptacles can matedly and removably receive respective ones of said finger clip housing arms and transmit and receive light through the apertures of said foam strip and through an appendage of a patient.

3. The disposable bandage defined in claim 2 wherein said modular receptacle includes a channel with a locking member.
