Abstract

A device and method of generating an enriched gas within a nasal vestibule of a patient includes a housing, a chamber, a chamber inlet, a pump, a molecular sieve bed, a release outlet, and a breath duct. The chamber is configured to be received within the nasal vestibule. The pump is configured to direct an ambient air from an ambient environment into the chamber. The molecular sieve bed is positioned within the chamber and configured to collect a predetermined molecule from the ambient air thereby generating the enriched gas. The release outlet is configured to discharge the enriched gas from the chamber into the nasal vestibule. The breath duct longitudinally extends through the housing such that the breath duct is configured to fluidly communicate a fluid flow through the housing for nasal breathing by the patient while the chamber is positioned within the nasal vestibule.

Dependent claims

A device for generating an enriched gas within a nasal vestibule of a patient, comprising:

a housing having a distal housing portion and a proximal housing portion;
a first chamber positioned within the housing and configured to be received within the nasal vestibule of the patient;
a first chamber inlet fluidly connected to the first chamber;
a first pump fluidly connected to the first chamber inlet and configured to direct an ambient air from an ambient environment into the first chamber via the first chamber inlet, the first pump including:
a first pump inlet,
a first pump outlet distally positioned relative to the first pump inlet,
a first piston chamber extending distally from the first pump inlet,
a first piston located within the first piston chamber,
a first duct conduit adjacent to the first piston chamber and configured to be in fluid communication with the first piston chamber,
a first chamber valve located proximate to the first pump inlet, and
a first duct valve located proximate to the first pump outlet;
a first molecular sieve bed positioned within the first chamber and configured to collect a predetermined molecule from the ambient air thereby generating the enriched gas;
a first release outlet fluidly connected to the first chamber and configured to discharge the enriched gas from the first chamber into the nasal vestibule;
and
a first breath duct longitudinally extending through the housing and having a first distal duct opening and a first proximal duct opening, the first distal duct opening being positioned in the distal housing portion and the first proximal duct opening being positioned in the proximal housing portion such that the first breath duct is configured to fluidly communicate a first fluid flow through the housing for nasal breathing through the housing by the patient while the first chamber is positioned within the nasal vestibule of the patient.

a first chamber positioned within the first lateral body and configured to be received within the nasal vestibule of the patient;
a first chamber inlet fluidly connected to the first chamber;
a first pump fluidly connected to the first chamber inlet and configured to direct an ambient air from an ambient environment into the first chamber via the first chamber inlet;
a first molecular sieve bed positioned within the first chamber and configured to collect a predetermined molecule from the ambient air thereby generating the enriched gas;
a first release outlet fluidly connected to the first chamber and configured to discharge the enriched gas from the first chamber into the nasal vestibule;
and
a first breath duct longitudinally extending through the first lateral body and having a first distal duct opening and a first proximal duct opening, the first distal duct opening being positioned in the distal housing portion and the first proximal duct opening being positioned in the proximal housing portion such that the first breath duct is configured to fluidly communicate a first fluid flow through the housing for nasal breathing through the housing by the patient while the first chamber is positioned within the nasal vestibule of the patient,
wherein the first proximal duct opening is positioned within the first outer profile and configured to discharge nasal breath directly from the first breath duct into the ambient environment.
