A system and method of use for an operational halotherapy device and red light device in an enclosed space. The halotherapy and red light system generally enclosed space, a red light device, and a salt aerosol discharge system that disperses salt particles into the air of the enclosure. The combination of both devices produces a refractory phenomenon when the red light waves make contact with the salt particles dispersed in the air to cause a plethora of multi-dimensional dispersions of light waves. Moreover, every time a salt particle makes contact with a red light wave, a portion of the wave light is absorbed by the particle, and its temperature increases, lessening the moisture in the particle. The lessening of moisture in the particle dries the particle further, which enhances the therapeutic properties of the inhalable salt particle.

A water reservoir configured to be removably connected to a respiratory pressure therapy (RPT) device has a water reservoir base configured to hold a volume of water to be used for humidification of the breathable air, a water reservoir lid connected to the water reservoir base, a retainer configured to engage with a corresponding portion of a water reservoir dock associated with the RPT device, thus securing the water reservoir to the water reservoir dock, and a portion of the lid being configured to receive a downward force to cause movement of the retainer against the bias of a spring, thus allowing removal of the water reservoir from the water reservoir dock.

Embodiments disclosed herein relate to respiratory interfaces for use in treating various respiratory issues including, but not limited to, sleep disorder breathing (e.g. snoring, sleep apnea), and in other forms of assisted and unassisted respiration. Embodiments disclosed herein further relate to nasal prongs, flanges and valves for use with respiratory interfaces. Embodiments disclosed herein further relate to evaluating patient compliance with a respiratory interface and harvesting energy for the respiratory.

A medical tube comprises a tail to connect an embedded wire to an electrical component. The tail may comprise a flattened portion and an exposed portion to facilitate attachment of the medical tube to an electrical component. The tail may comprise a second flattened portion. One or more wires, such as a heater wire or a sensor wire, may be embedded in the medical tube. The medical tube may comprise a connector that comprises a printed circuit board to which the one or more wires is attached. The connector may comprise features to support the printed circuit board, aid in assembly of the one or more wires to the connector, and protect electrical components against liquid ingress.

Systems and methods are disclosed for categorizing and/or characterizing a user interface. The systems and methods include generating acoustic data associated with an acoustic reflection of an acoustic signal, the acoustic reflection being indicative of, at least in part, one or more features of a user interface coupled to a respiratory therapy device via a conduit. The systems and methods further include analyzing the generated acoustic data. The systems and methods further include categorizing and/or characterizing the user interface based, at least in part, on the analyzed acoustic data.

Sleep performance scores can be generated for an individual receiving respiratory therapy. Sensor data can be obtained from one or more sensors while the user is sleeping and using a respiratory therapy system. The sensor data can be used to determine one or more usage variables associated with use of the respiratory therapy system, as well as sleep stage information indicative of the stages of sleep undergone by the user while sleeping. A sleep performance score can be calculated using the one or more usage variables and the sleep stage information. In some cases, the sleep stage information can be used to apply weightings to one, some, or all of the one or more usage variables. The sleep performance score can indicate compliance, efficacy, quality, and/or general use of the respiratory therapy system, taking into account the relationship between sleep stage and use of the respiratory therapy system.

A medical gas condition system for supplying a liquid hydration fluid to a hydrator before or during an ongoing medical procedure by coupling the flow of liquid hydration fluid into the hydrator to either the absence of flow of medical insufflation gas into the hydrator or to a condition where the liquid hydration fluid can be absorbed by a hydrator without being forced through the hydrator in liquid form.

An apparatus for the supply of humidified gases to a patient is disclosed that comprises a gases supply passage downstream of a humidified gases supply, and upstream of a patient in use, where at least one sensor is embedded in or located on the outside of the wall of the passage. In preferred forms the wall of the passage divides the sensor(s) from a flow of gases in the passage. In use, a controller receives an output of the sensor(s) and derives from the output of the sensor(s) an estimation of a property of gases flowing through the passage or provides a control output to the humidified gases supply according to the output of the sensor(s).

A humidification arrangement can be configured to have multiple compartments with each compartment having at least one moisture source and at least one heater. The compartments can be thermally isolated and can be controlled such that the moisture output of both the first and second compartments is set to a function of the same set of input signals.

A nasal cannula for use in a system for providing a flow of respiratory gases to a user is described. The nasal cannula comprises a body made from a pliable material. The body has an inlet and at least one nasal prong fluidly connected to the inlet. In use a conduit providing a flow of gases to the cannula is connected to the inlet, and the nasal prong is inserted into a user's nostril. The cannula is arranged to direct the flow of gases from the nasal prong towards the front wall of the user's nasal passage within the user's nose.
