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.

Abstract: A system and method of standardizing modular probe housings so that the standardized probe housings may be incorporated into probes adapted to work with at least one of a multiplicity of manufacturers' oximeters. The probe housings are adapted to matingly engage at least a disposable bandage apparatus and a reusable finger attachment device.

Abstract: A method of facilitating the intra-departmental or inter-institutional transport of a patient or patients requiring the pulse oximeter monitoring, and wherein the pulse oximeters used for monitoring the patient may be of different manufacturers, comprising affixing to the patient a bandage apparatus having a modular emitter and detector receptacles incorporated thereon. Each different manufacturers' pulse oximeter probe is provided with modular housings adapted to matedly engage and/or disengage the receptacles of the disposable bandage apparatus, thus enabling the patient to be monitored by pulse oximeters of different manufacturers without changing the bandage apparatus.

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.

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.

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.

Abstract: A piston flow meter for measuring the flow of a gaseous fluid, such as ambient air, through the flow meter by timing the displacement of a piston in a hollow precision bore flowtube over a fixed distance. The piston is reciprocated from opposite ends of the flowtube by a poppet valve which controls the direction of movement of the piston in the flowtube. Ambient air is drawn into the flow tube from the atmosphere by an external pump connected to an inlet at one end of the flowtube. The flow meter includes a damping assembly for damping pulsations in gas flow through said flowtube with the damping assembly preferably located adjacent the pump inlet to the external pump. The damping assembly comprises damping means which includes a porous member and at least one elastic diaphragm contiguous thereto with the porous member having a multiplicity of voids and a plurality of open channels extending through the porous member to the elastic diaphragm.
