## Abstract

A therapy device that includes an air conduit that is configured both to secure the patient interface to the patient as well as provide pressurised air to the patient. The positioning and stabilising structure of the patient interface may include magnets that assist in positioning the positioning and stabilising structure and also assist in positioning the air conduit of the positioning and stabilising structure to interact with the mask assembly.

## Claims

### Claim 1

A system comprising:
an RPT device and a patient interface, and an air circuit connecting the RPT device to the patient interface;
the RPT device configured to supply air at positive pressure for respiratory therapy;
the air circuit connected to the patient interface at a connection port;
the patient interface including a positioning and stabilising structure and a mask assembly including a plenum chamber and a seal forming structure, the positioning and stabilising structure including a headgear conduit for receiving a therapeutic pressure of at least 6 cmH2O above ambient air pressure from the air circuit, the headgear conduit extending along a crown of the patient's head from a first parietal bone to a second parietal bone;
the plenum chamber including a plenum chamber opening sized and structured to receive a flow of air at the therapeutic pressure for breathing by a patient, the plenum chamber including a first plenum chamber receptor assembly;
the seal forming structure constructed and arranged to form a seal with a region of the patient's face surrounding an entrance to the patient's airways, said seal forming structure having a hole therein such that the flow of air at said therapeutic pressure is delivered to at least an entrance to the patient's nares, the seal forming structure constructed and arranged to maintain said therapeutic pressure in the mask assembly throughout the patient's respiratory cycle in use;
the headgear conduit including a first end with a first conduit connector assembly and configured to deliver air through the first conduit connector assembly and through the first plenum chamber receptor assembly;
wherein the first conduit connector assembly is configured to engage with the first plenum chamber receptor assembly, and be rotatable about an axis that extends through the first plenum chamber receptor assembly; and
wherein when the first conduit connector assembly is engaged with the first plenum chamber receptor assembly the first conduit connector assembly is restricted from translating in a first direction perpendicular to the axis, and permitted to translate in an opposite second direction.

### Claim 2 (depends on 1)

The system according to claim 1, wherein the plenum chamber and the first conduit connector assembly are attracted to each other through a magnetic force, a seal being formed between the plenum chamber and the first conduit connector assembly.

### Claim 3 (depends on 1)

The system according to claim 1, wherein the first conduit connector assembly includes a connector opening wherein the magnetic force self-aligns the connector opening with the plenum chamber opening.

### Claim 4 (depends on 1)

The system according to claim 1, wherein when the patient interface is worn by the patient the first conduit connector assembly is a tie and provides a posterior force to the mask assembly.

### Claim 5 (depends on 1)

The system according to claim 1, wherein the first conduit connector assembly is configured to be rotatable about the first plenum chamber receptor assembly while maintaining a seal between the first conduit connector assembly and the first plenum chamber receptor assembly.

### Claim 6 (depends on 1)

The system according to claim 1, wherein the headgear conduit further comprises a second end with a second conduit connector assembly and the mask assembly including a second plenum chamber receptor assembly, wherein the second conduit connector assembly is configured to engage with the second plenum chamber receptor assembly, wherein air is configured to pass through the second conduit connector assembly and through the second plenum chamber receptor assembly.

### Claim 7 (depends on 1)

The system according to claim 1, wherein the first conduit connector assembly includes a retention member, and wherein the first plenum chamber receptor assembly includes a tapered outer wall, wherein the retention member is angled to engage with the outer wall of the first plenum chamber receptor assembly, wherein an inner surface of the retention member is substantially linear and an outer surface of the outer wall is substantially linear.

### Claim 8

A patient interface for providing a flow of air pressurized above ambient to a patient's upper airways sufficient to treat sleep-disordered breathing, comprising:
a cushion assembly including a cushion inlet port to receive a flow of air for breathing by the patient;
at least one inlet conduit to at least partially support and position the cushion assembly on the patient's head, the inlet conduit being configured to deliver the pressurized flow of air to the cushion inlet port; and
a magnetic connector to magnetically connect the at least one inlet conduit to the cushion assembly, the magnetic connector comprising an intermediate air flow path that pneumatically connects the at least one inlet conduit to the cushion inlet port.

### Claim 9 (depends on 8)

The patient interface according to claim 8, further comprising a retention member that detachably interfaces with the cushion assembly, the retention member being structured and positioned to at least partially counteract tension forces tending to separate the at least one inlet conduit from the cushion assembly.

### Claim 10 (depends on 8)

The patient interface according to claim 8, further comprising a magnetic retaining member to assist in maintaining a sealing contact between the at least one inlet conduit and the cushion inlet port.
