Abstract:
An expiratory limb for a breathing circuit includes an enclosing wall defining a flexible singular expiratory flow passage between an inlet and an outlet and bounding the flexible singular expiratory flow passage and ambient air. The expiratory limb includes one or more regions of the enclosing wall that made from a material that allows passage of water vapor without allowing passage of liquid water, thereby forming a water vapor flow path from the flexible singular expiratory flow passage to the ambient air through the material. The expiratory limb is configured to allow diffusion of water vapor along the flexible singular expiratory flow passage and dry the flow of expiratory gases between the inlet and the outlet.

Claim (Index 14):
A method of manufacturing an expiratory conduit for a respiratory breathing system, the method comprising:\n extruding a single corrugated flexible tube entirely from a breathable hydrophilic thermoplastic material that allows passage of water vapor without allowing passage of liquid water, tube comprising a diameter sufficient to allow an entirety of a expiratory flow of gases from a patient to pass through the tube; providing an inlet connector configured to connect to and receive a flow of expiratory gases from a patient interface component; providing an outlet connector configured to connect to and deliver the flow of expiratory gases to other equipment; connecting the inlet connector to a first end of the extruded corrugated flexible tube; and connecting the outlet connector to a second end of the extruded corrugated flexible tube; wherein, in use, the expiratory conduit receives a flow of expiratory gases from a patient and allows water vapor to pass through the corrugated flexible tube directly from the flow of expiratory gases to ambient without allowing passage of liquid water.
