Abstract

A connection system for connecting gas delivery components of a Continuous Positive Airway Pressure system includes a first conduit with a first lumen forming a first part of a gas flow path for the breathable gas and a second conduit with a second lumen forming a second part of the gas flow path. The ends of each flexible connector include a magnets. The first and second flexible connectors are configured to be joined together to form a sealed connection by way of moving the first and second flexible connectors toward each other in an axial direction and are configured to be held together by a magnetic force between the first and second magnets. In addition, the first and second flexible connectors are configured to be separated from each other by pivoting the first and second connectors relative to each other.

Claims (34)

1 . A connection system for connecting gas delivery components of a continuous Positive Airway Pressure (CPAP) system that is configured to deliver a pressurized flow of breathable gas to a patient's airways, the connection system comprising:

a first conduit with a first lumen forming a first part of a gas flow path for the breathable gas, one end of the first conduit comprising a first connector with a first magnet;

a second conduit with a second lumen forming a second part of the gas flow path for the breathable gas, one end of the second conduit comprising a second connector with a second magnet, the second connector being configured to be joined to the first connector to form a sealed connection by way of moving the first and second connectors toward each other in an axial direction; and

a cover comprising two arms connected to each other by a hinge and a locking mechanism at an end of at least one of the two arms, the cover being configured to enclose a joint created when the sealed connection is made,

wherein the first and second connectors are configured to be held together by a magnetic force between the first and second magnets, and

wherein the first and second connectors are configured to be separated from each other by pivoting the first and second arms of the cover relative to each other.

2 . The connection system of claim 1 , wherein the first and second connectors comprise hand grips in the form of contours and/or grooves.

3 . The connection system of claim 1 , wherein the first magnet forms a ring around the first lumen and the second magnet forms a ring around the second lumen.

4 . The connection system of claim 1 , further comprising a projection extending axially from said one end of the first connector, the projection being configured to be inserted into the second flexible connector upon the first and second connectors being joined together.

5 . The connection system of claim 4 , wherein the first lumen extends through a central portion of the projection.

6 . The connection system of claim 4 , wherein the projection extends beyond the first magnet.

7 . The connection system of claim 4 , wherein the projection is tapered toward a terminal end of the first connector.

8 . The connection system of claim 1 , wherein the cover is flexible.

9 . The connection system of claim 1 , wherein the cover is attached to one of the first flexible connector or the second connector.

10 . The connection system of claim 1 , wherein the first and second connectors are flexible.

11 . The connection system of claim 1 , wherein the cover is a clamp.

12 . The connection system of claim 11 , wherein the clamp is magnetic.

13 . The connection system of claim 11 , wherein the clamp comprises an elastic sleeve stretched over at least one of the first and second connectors.

14 . The connection system of claim 1 , further comprising a projection extending axially from said one end of the first connector, the projection being configured to be inserted into the second connector upon the first and second connectors being joined together,

wherein the first and second connectors comprise hand grips in the form of contours and/or grooves,

wherein the first magnet forms a ring around the first lumen and the second magnet forms a ring around the second lumen,

wherein the first lumen extends through a central portion of the projection,

wherein the projection extends beyond the first magnet, and

wherein the projection is tapered toward a terminal end of the first connector.

15 . The connection system of claim 14 ,

wherein the cover is a clamp,

wherein the clamp is magnetic, and

wherein the clamp comprises an elastic sleeve stretched over at least one of the first and second connectors.

16 . A continuous Positive Airway Pressure (CPAP) system configured to deliver a pressurized flow of breathable gas to a patient's airways, the CPAP comprising:

a flow generator configured to pressurize the flow of breathable gas; and

the connection system of claim 1 ,

wherein the connection system is configured to convey the pressurized flow of breathable gas from the flow generator.

17 . The CPAP system of claim 16 , further comprising a patient interface configured to sealingly engage a patient's face,

wherein the patient interface is connected to the connection system and receives the pressurized flow of breathable gas from the connection system.
