Abstract

Nasal respiratory assembly includes a pair of sheets. Each sheet defines an opening sized and shaped to fit over a nostril of a patient, with a ferromagnetic dome-shaped ring positioned at an underside of the sheet, with an upper side of the sheet configured for sealable engagement with the nostril. The assembly also includes a pair of posts. Each post includes a magnetic ring positioned at a first end and a ball shaped receptacle positioned at a second end. The magnetic ring is removably attachable to the dome-shaped ring. The assembly further includes a pair of conduit adapters with openings therethrough for fluid flow. A post end of each conduit adapter includes a socket, each socket shaped to receive the ball shaped receptacle in a ball and socket arrangement to form a substantially airtight connection therewith.

Claims (34)

1 . A nasal respiratory assembly comprising:

a pair of sheets, each sheet defining an opening sized and shaped to fit over a nostril of a patient, with a ferromagnetic dome-shaped ring positioned at an underside of the sheet and circumferentially aligned with the opening, with an upper side of the sheet configured for sealable engagement with the nostril,

wherein the dome shaped ring comprises

a flat disc portion having a first side contacting the underside of the sheet, an opposed second side, and a peripheral edge between the first side and second side,

a dome portion having a base adjacent to the second side of the flat disc portion, an apex at an opposed end of the dome portion form the sheet and the flat disc portion, and a curving surface disposed between the base and the apex and extending from the second side of the flat disc portion to the apex of the dome portion, and

a passage through the dome-shaped ring from a first aperture defined in the first side of the flat disc portion to a second aperture defined in the surface of the dome portion at the apex;

a pair of posts, each post including a cylindrical magnetic ring, having a pathway therethrough, positioned at a first end and a ball shaped receptacle positioned at a second end with a passageway extending from the first to the second ends and through the pathway, the magnetic ring removably attachable to the dome-shaped ring;

a pair of conduit adapters having an hourglass shaped exterior and defining openings therethrough for fluid flow, a post end of each conduit adapter including a socket, each socket configured to receive and secure the ball shaped receptacle of a post in a ball and socket arrangement to form a substantially airtight connection therewith;

wherein a connector end of each conduit adapter cooperates with a channel opening of a connector of a continuous positive airway pressure (CPAP) machine to form a substantially airtight connection therewith.

2 . The assembly of claim 1 , wherein each ball shaped receptacle is configured to form an interference fit with the socket of the conduit adapter.

3 . The assembly of claim 1 , wherein the connector end of the conduit adapter encircles the channel opening of the connector to form an interference fit therewith.

4 . The assembly of claim 1 , wherein the channel opening of the connector stretches over and encircles the connector end of the conduit adapter to form an interference fit therewith.

5 . The assembly of claim 1 , wherein one or more of: an interior of the conduit adapter defines an approximate cylindrical opening, and an exterior of the conduit adapter defines an approximate hour-glass shape.

6 . The assembly of claim 1 , wherein the conduit adapter comprises an elastomeric material or low-density polyethylene (LDPE).

7 . The assembly of claim 1 , wherein the assembly lacks straps, masks, or both.

8 . The assembly of claim 1 , wherein a wall thickness of the conduit adapter varies along a height of the conduit adapter.

9 . The assembly of claim 1 , wherein a wall thickness of the conduit adapter decreases progressively moving from ends of the conduit adapter towards a mid-height section of the conduit adapter and the connector end towards a mid-height section of each conduit adapter and wherein each conduit adapter has a consistent diameter pathway disposed therethrough between the openings and from the post end to the connector end.

10 . The assembly of claim 1 , wherein an upper surface of the post is angled.

11 . The assembly of claim 1 , wherein an opening of the magnetic ring has a round, oblong, oval or tear drop shape, wherein the shape of an opening of the dome-shaped ring compliments the shape of an opening of the magnetic ring.

12 . The assembly of claim 1 , wherein an inlet at a vent end of the connector is in fluid communication with a flexible tubing connected to a fluid source.

13 . The assembly of claim 1 , wherein the connector is part of a generic off-the-shelf continuous positive airway pressure (CPAP) machine.

14 . The assembly of claim 1 , wherein the fluid is supplied from a high flow generator, a continuous positive airway pressure (CPAP) machine, a fluid tank, or a humidifier.

15 . A nasal respiratory assembly comprising:

a pair of sheets, each sheet defining an opening sized and shaped to fit over a nostril of a patient, with a ferromagnetic ring positioned at an underside of the sheet and circumferentially aligned with the opening having a passage in fluid communication with the opening, with an upper side of the sheet configured for sealable engagement with the nostril,

wherein the ferromagnetic ring comprises a flat disc having a first side contacting the underside of the sheet, an opposed flat second side and a peripheral edge between the first side the second side, and

wherein the passage extends through the ferromagnetic ring from the first side to the second side;

a pair of posts, each post including a cylindrical magnetic ring, having a pathway therethrough, positioned at a first end and a receptacle positioned at a second end with a passageway extending from the first to the second ends and through the pathway, the magnetic ring removably attachable to the ferromagnetic ring;

a pair of conduit adapters having an hourglass shaped exterior and defining openings therethrough for fluid flow, a post end of each conduit adapter including a socket, each socket shaped to receive the receptacle in an interference fit to form a substantially airtight connection therewith;

wherein a connector end of each conduit adapter cooperates with a channel opening of a connector of a continuous positive airway pressure (CPAP) machine to form a substantially airtight connection therewith; and

wherein a wall thickness of each conduit adapter decreases progressively moving from both the post end and the connector end towards a mid-height section of each conduit adapter and wherein each conduit adapter has a consistent diameter pathway disposed therethrough between the openings and from the post end to the connector end.

16 . The assembly of claim 15 , wherein an interior of the conduit adapter defines an approximate cylindrical opening.

17 . The assembly of claim 15 , wherein the conduit adapter comprises an elastomeric material.

18 . The assembly of claim 15 , wherein the assembly lacks straps, masks, or both.

19 . The assembly of claim 15 , wherein an opening of the magnetic ring has a round, oblong, oval or tear drop shape, wherein the shape of an opening of the ferromagnetic ring compliments the shape of an opening of the magnetic ring.
