Abstract: A breathing assistance system for providing breathing assistance to a patient includes a gas delivery system configured to generate a gas flow, a patient interface configured to interface with the patient, a connection system connected between the gas delivery system and the patient interface and configured to communicate the gas flow to the patient interface for delivery to the patient, and a sensor system remote from the gas delivery system and connected to at least one of the patient interface and the connection system. The sensor system may include a sensor for measuring a parameter, one or more actuators, and a power supply based on a turbine configured to be driven by the gas flow and an electrical generator coupled to the turbine and configured to generate electricity.

Abstract: A breathing assistance system for providing breathing assistance to a patient is provided. The breathing assistance system may include a ventilation system for supplying a gas flow, a conduit operatively coupled to the ventilation system, and a pressure sensor configured to measure the pressure of the gas flow through the conduit. The pressure sensor may include a structure configured to create a localized pressure drop in the gas flow proximate the pressure sensor structure.

Abstract: A breathing assistance system includes a gas delivery system that generates a gas flow, a fluid source (e.g., a humidifier system or supplemental gas supply) located downstream from the gas delivery system that humidifies the gas flow generated by the gas delivery system, a gas flow conduit system for communicating the gas flow from the gas delivery system, and a flow regulation device. The flow regulation device is physically moveable between (a) an operational position that allows the gas flow generated by the gas delivery system to flow downstream past the flow regulation device via the gas flow conduit system, and (b) a protection position that prevents gasses and liquids flowing upstream through the gas flow conduit system from reaching the gas delivery system, and instead directs such gasses and liquids through an exhaust opening in the gas flow conduit system.

Abstract: A breathing assistance system includes a gas delivery system including a gas flow generation device configured to generate a gas flow; a humidifier system including a liquid water chamber and an outlet, and a microporous filter. The gas delivery system and the humidifier system at least partially define a gas flow path from the gas flow generation device to the outlet of the humidifier system. The microporous filter is located along the gas flow path such that the gas flow generated by the gas flow generation device flows through the microporous filter, subsequently becomes humidified in the liquid water chamber, and subsequently flows through the outlet of the humidifier system. The microporous filter is gas-permeable and liquid water-impermeable, such that the microporous filter prevents liquid water in the liquid water chamber from flowing into the gas flow generation device in any orientation of the gas delivery system and humidifier system.
