Disclosed herein are novel designs of a medical tube for delivering a respiratory gas to a subject in respiratory therapy, wherein the medical tube is in fluid connection with a user interface and a respiratory device. The medical tube has a tubular body, a first rib helically extending along the outer surface of the tubular body, and optionally, a second rib disposed next to the first rib, and optionally, a membrane encapsulating the first and/or second ribs thereby creating a helical space along the outer surface of the tubular body. In some embodiments, the first rib has a lumen and at least one wire disposed outside the lumen. In other embodiments, the first rib is free of any lumen and includes one or more wires extended therethrough. The lumen of the first rib or the helical space created by membrane encapsulation is configured to monitor the temperature, humidity, flow rate or pressure of the respiratory gas or an exhaled/inhaled gas of a subject.

The present invention relates to a device (100) and a system for positive pressure ventilation (PPV) and continuous positive airway pressure (CPAP) treatment comprising a fresh gas flow inlet (2), arranged to receive a fresh gas flow from a fresh gas flow tube (22) connectable thereto; a patient interface end (3), arranged to be connected with a patient interface; an outlet (4) having an open end (5); a variable flow CPAP generator (6) comprising first, second and third connection portions (10, 11, 12), wherein the first connection portion is connected with the fresh gas flow inlet, the second connection portion is connected with the patient interface end, and the third connection portion is connected with the outlet, wherein the generated CPAP level is adjusted by varying the fresh gas flow to the variable flow CPAP generator. The device further comprises an internal leakage channel (9) arranged to extend between the fresh gas flow inlet and at least one of the patient interface end and the outlet, such to create an internal fresh gas leakage flow there between, bypassing the first connection portion of the variable flow CPAP generator, which is added to the fresh gas flow provided by the variable flow CPAP generator in the PPV mode. A simplified device and system is provided, respectively, which is easy to use and allows for a rapid switch between PPV and CPAP treatment without change of equipment.

A nasal interface is provided that can allow for delivery of flow of a gas to a patient for respiratory support while preventing injury or irritation to the patient. The nasal interface can include a nasal pillow set having a nasal pillow, which can engage against a nose, and relief port, which can permit a gas to be released from the nasal interface. A nasal cannula can include a cannula body to direct a gas through the nasal interface, and can have an opening to direct a gas out of the cannula body. The gas can be directed from the cannula body, through the opening, toward a nasal pillow and a patient's nare. The nasal interface can be coupled with a head harness, which can be worn on the patient's head, and can include a guide that extends toward the nasal interface.

A patient interface including a seal-forming structure with a textile membrane that has at least one hole such that the flow of air at a therapeutic pressure is delivered to at least an entrance to the patients nares and/or an entrance to the patients mouth. The seal-forming structure is constructed and arranged to maintain the therapeutic pressure in a cavity of a plenum chamber throughout the patients respiratory cycle, in use. The textile membrane includes a first portion that is held in a relaxed state and a second portion that is held in a taut state. The taut state of the second portion is configured to allow the seal-forming structure to include a three-dimensional shape that has multiple curvatures.

A breathing assistance apparatus includes an inner volumetric member pressurizable from a first pressure to a second pressure and an outer volumetric member surrounding at least a portion of the inner expandable volumetric member. The inner volumetric member pressurizes the outer volumetric member as the inner volumetric member is pressurized from the first pressure to the second pressure. In another embodiment, a breathing assistance apparatus includes exhalation and inhalation chambers with respective biasing members providing for the exhalation chamber to apply a pressure to the inhalation chamber and thereby provide assisted inhalation. Methods for assisting breathing are also provided.

Systems and methods are disclosed for delivering medication to a patient. One such system has an aerosol generator for aerosolizing medication. The generator is located outside the airway of a patient. A chamber is provided for receiving aerosolized medication from the generator. The system has a carrier gas supply tube for delivering carrier gas to the chamber, and an aerosol delivery tube for receiving the aerosolized medication and the carrier gas from the chamber. The aerosol delivery tube delivers the aerosolized medication to the patient. A distal end of the aerosol delivery tube is positioned inside the airway of the patient in order to discharge the aerosolized medication within the patient's airway.

The invention relates to a ventilation monitoring system comprising a ventilation data capturing device connected between a patient and a ventilator device dedicated to the patient, for collecting ventilation data between the patient and ventilator device; an on-site device; a remote device for communicating with the ventilation data capturing device and the on-site device; at least one processor; and at least one memory device coupled to the at least processor configured to: collect ventilation data from the ventilation data capturing device; transmit the collected ventilation data to the remote device/server for analysis; and generate output data comprising the instructions/commands for actioning on the ventilator device, to provide suitable ventilation support to the patient, or generate output data comprising the status of the ventilator device associated with the ventilation data capturing device.

A gas delivery conduit adapted for fluidly connecting to a respiratory gases delivery system in a high flow therapy system. In one embodiment, a nasal cannula includes a base portion defining a first therapeutic gas passageway, a nozzle disposed adjacent the base portion and defining a second therapeutic gas passageway, the first passageway being in gaseous communication with the second passageway and a conduit configured to facilitate sensing that has an inlet side that is independent of and axially spaced apart from an outlet side of the nozzle. The conduit inlet side can extend beyond the nozzle outlet side of the nasal cannula. Additionally, the nasal cannula has a feature adapted to prevent one of the conduit and the nozzle from creating a seal with a user's rare and a feature adapted to prevent one of the conduit and the nozzle from creating a seal with a user's nare.
