A breathing assistance apparatus is configured with features that improve serviceability of the apparatus. The apparatus can include animations to provide instruction regarding correcting easily-identified fault conditions and to provide instruction regarding routine maintenance routines. The apparatus also can be configured with top level control menus that are obscured in a manner to limit manipulation of the top level control elements by unauthorized users.

A patient interface for respiratory therapy includes a nasal interface having nasal prongs configured to contact nares of the user and form a seal. The patient interface also includes a securement portion having a pair of facial pads, each of the facial pads configured to engage the face of a user on opposing sides of the nasal interface. The facial pads are coupled to the bridging portions configured to urge the nasal interface toward the user's face to create or maintain sealing engagement between the nasal interface and the user's face. In some configurations, the securement portion and the nasal interface are detachably coupled to each other.

Example embodiments of the present invention provide a multi-function oral appliance, comprising an elastomeric polymer, a hard non-elastic polymer, or a combination of the two fused together; formed using 3D printing or vacuum-forming; configured to engage all or part of the bottom and top teeth such that the lower jaw is advanced, e.g., 8 mm, anterior to its habitual resting position and opened, e.g., 8 mm, from its habitual resting position when the appliance is applied; and configured such that, e.g., 90%, or more, of airflow through the mouth is blocked by the appliance. In some embodiments, the appliance is configured to include gel-wells in the interior of the appliance.

An oxygen mask may include a convex shell having an upper portion and a lower portion and defining a chamber, a rim at least partially around the chamber, a nasal access port in the upper portion, and an oral access port in the lower portion. The nasal access port that is penetratable and/or puncturable to provide access to the chamber, and the oral access port may include a bite block defining a lumen and a valve in the lumen. The oxygen mask may include an inlet into the chamber, an outlet from the chamber, and a sampling port in communication with the chamber. The oxygen mask may include at least one fold or crease configured to allow the bite block to tilt relative to the horizontal axis and/or to translate along the vertical axis.

A ventilator includes a bidirectional breath detection airline and a flow outlet airline. The flow outlet airline includes an airline outlet. The flow outlet airline is configured to be connected to an invasive ventilator circuit or a noninvasive ventilator circuit. The breath detection airline includes airline inlet. The airline inlet is separated from the airline outlet of the flow outlet airline. The ventilator further includes a pressure sensor in direct fluid communication with the breath detection airline. The pressure sensor is configured to measure breathing pressure from the user and generate sensor data indicative of breathing by the user. The ventilator further includes a controller in electronic communication with the pressure sensor. The controller is programmed to detect the breathing by the user based on the sensor data received from the pressure sensor.

Systems, devices, and methods for coupling a tracheostomy tube to a source of humidified breathing gas are disclosed. An adaptor includes a housing, a tracheostomy tube connection device, and a baffle. The housing has an interior surface, an exterior surface, and a breathing gas port. The tracheostomy tube connection device is positioned within the housing and includes an input port for receiving a flow of humidified breathing gas from the breathing gas port and an output port for coupling with the tracheostomy tube. The tracheostomy tube connection device has an internal surface defining a breathing gas passage and an external surface spaced from the interior surface of the housing to create a condensation passage. The baffle may be positioned between the breathing gas port and the input port to cause controlled condensation from the flow of humidified breathing gas by disrupting the flow of humidified breathing gas.

An air conduit for a respiratory therapy device comprises a first end, a second end, and a tube portion, wherein the tube portion comprises a tube wall and an auxiliary structure, such as a rib. The air conduit may deliver a flow of air from a respiratory therapy device or a humidifier to a patient interface. The air conduit may comprise a plurality of auxiliary structures, some of which may consist of a polymeric material, and some of which may comprise a polymeric material and an electrical conductor. An auxiliary structure may be a helical rib extending across a length of the tube portion.

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.

A patient interface includes: a plenum chamber; a seal-forming structure; a positioning and stabilising structure; a plenum chamber insert configured to be positioned and retained within the plenum chamber; and a vent structure; wherein the plenum chamber insert has a plenum chamber insert port; wherein the plenum chamber insert has an exterior surface configured to be positioned adjacent to an interior surface of the plenum chamber; wherein when the plenum chamber insert is positioned and retained within the plenum chamber, a radial channel is formed by the interior surface of the plenum chamber and the exterior surface of the plenum chamber insert such that gas is able to pass between a patient-proximal side of the plenum chamber insert and a patient-distal side of the plenum chamber insert via the radial channel during use.

A respiratory drug delivery device and a method for automating drug delivery are provided. The respiratory drug delivery device may be utilized for delivering a drug to a patient's respiratory tract. The respiratory drug delivery device comprises an inhalation element, an air pipe, a sound sensor, and a drug delivery module, the drug delivery module delivers an aerosolized medicine when the patient inhales based on a sound signal.
