Abstract: An apparatus for delivering a flow of gas, has a housing 3202? with a recess, and an outlet port 3210? for a flow of gas. The recess is defined by at least one wall 3256, 3262 that is substantially continuous, gas impermeable, and unbroken, other than a gasflow passage from the recess to the outlet port of the housing.

Abstract: The gases temperature supplied to a patient when the patient is undergoing treatment such as oxygen therapy or positive pressure treatment for conditions such as Obstructive Sleep Apnea (OSA) or Chronic Obstructive Pulmonary Disease (COPD) is often measured for safety and to enable controlling of the humidity delivered to the patient. The invention disclosed is related to measurement of properties, particularly temperature (thermister 23), of gases flowing through a heated tube (3), supplying gases to a patient, which utilises the heating wire (21, 28) within the tube.

Abstract: The present invention provides a breathing assistance apparatus that has a convenient and effective method of cleaning internal conduits inside the apparatus. The breathing assistance apparatus is preferably a gases supply and humidification device. The cleaning method is a method of disinfection that is automated so minimal training is required to disinfect in particular an internal elbow conduit within the device. It is therefore not necessary to dismantle the gases supply and humidification device, therefore, inadvertent damage to the internal parts of the device is avoided. The present invention also provides a method of disinfecting a heated breathing conduit and a patient interface.

Abstract: A respiratory therapy system can have a flow generator adapted to provide gases to a patient. A gas passageway can be located in-line with the flow generator. The gas passageway can have a first portion adapted to receive a first gas and a second portion adapted to receive a second gas. The gas passageway can have a static mixer downstream of the first and second portions.

Abstract: Patient interface, such as a nasal cannula, with a headgear. The interface has a soft face mount part with nasal prongs and a base portion, and a harder-material gases flow manifold part with an inlet and an outlet. Gas is delivered into the manifold inlet, and flows out through the outlet and into the base portion of the face mount. The outlet of the manifold part comprises a groove that creates a gap between the base portion of the face mount and the manifold part at a region adjacent to the philtrum, providing pressure relief on the septum. The headgear has straps. Portions of the headgear that contact facial regions have surface regions for frictionally engaging with the skin. The material in these regions can be in the form of sleeves or coatings or over-moulding. The remainder of the strap has different material properties from those contacting the facial region.

Abstract: A respiratory assistance apparatus (4) is provided, adapted to deliver gases to a user or patient (1). The apparatus (4) comprises a housing (10) provided with a chamber (5) and a heater (25), the chamber (5) comprising at least one gas port (15) connected to, or arranged to be connected to, at least one intermediate passageway (12). The apparatus (4) is operative according to a disinfection mode of predetermined profile in which the heater (25) heats liquid in the chamber (5) to produce vapour at or above a target dewpoint temperature and/or humidity level. The apparatus (4) is arranged such that the vapour is delivered to the intermediate passageway (12) to disinfect the intermediate passageway (12) with moist heat throughout a predetermined duration of the disinfection mode. Associated attachments and methods are also provided.

Abstract: A respiratory assistance apparatus has a gases inlet configured to receive a supply of gases, a blower unit configured to generate a pressurised gases stream from the supply of gases; a humidification unit configured to heat and humidify the pressurised gases stream; and a gases outlet for the heated and humidified gases stream. A flow path for the gases stream extends through the respiratory device from the gases inlet through the blower unit and humidification unit to the gases outlet. A sensor assembly is provided in the flow path before the humidification unit. The sensor assembly has an ultrasound gas composition sensor system for sensing one or more gas concentrations within the gases stream.
