This disclosure relates to methods and apparatus for treating diseases and conditions of the colon and alimentary canal which are associated with obligate anaerobic microorganisms, and particularly, for treating Clostridioides difficile infection. The method and apparatus provide for continuous administration of intraluminal oxygen to the rectum, colon, and cecum to maintain oxygen in those environments at levels toxic to obligate anaerobic microorganisms such as Clostridioides difficile.

A valve apparatus comprises a housing having an inlet port, an outlet port, a selectable flow port, and a vent. The apparatus further comprises a valve member which is moveable between:

a first position in which a flow path between the inlet port and the selectable flow port is substantially blocked and in which the vent is fluidly connected to the selectable flow port; and

a second position in which a flow path between the selectable flow port and the vent is blocked, and the selectable flow port is fluidly connected to the inlet port.

A vent assembly for a respiratory pressure therapy (RPT) system. The vent assembly may include a vent housing having a first orifice configured to receive the flow of pressurized gas from the RPT device and the vent housing having a plurality of holes to discharge pressurized gas to atmosphere; a vent housing connector having a second orifice configured to direct the flow of pressurized gas to the patient interface; and a heat and moisture exchanger (HME) comprising an HME housing and an HME material within the HME housing, wherein the vent housing and the vent housing connector are configured to be connected to, at least in part, form a cavity, and wherein the HME is positioned in the cavity when the vent assembly is assembled.

In one embodiment, the present invention provides a system to deliver at least one therapeutic gas to a spontaneously breathing patient, wherein the rate of delivery of the at least one therapeutic gas exceeds the patient's inspiratory flow rate, and the amount of the at least one therapeutic gas that is wasted is minimized or eliminated.

A patient interface for treating sleep disorder breathing includes a textile tube that also provides support for the seal forming structure. The textile tube includes an inner and outer layer that are joined along seams to form an air chamber or passageway. The textile tube can be pre-shaped so that the textile tube resiliently returns to a pre-determined shape prior to the introduction of pressurized air.
