A medicine vaporizer apparatus comprises a base with an upwardly extending heating element disposed within a rigid tube. Air is drawn into the rigid tube through an aperture in the rigid tube below the heating element and directed over the heating element to then be drawn through a flexible tube and through a filter or screen comprising an amount of medicine. Heated air flows over the amount of medicine and vaporizes the same, wherein the medicine is thereafter drawn into the lungs of a patient pulling the air therethrough with his or her mouth. Thermal separation and cooling of various parts prevents accidental injury to users and provides an inert air path for the air therethrough. The apparatus further provides controlled incineration and/or vaporization of the medicine.

A system for providing continuous positive air pressure therapy is provided. The system includes a flow generator, a sensor, and a computing device. The computing device is configured to control operation of the flow generator based on sensor data. The computing device is further configured to display, on a display device, one or more questions relating to demographic and/or subjective feedback; responsive to displaying the one or more questions, receive one or more inputs indicating answers to the one or more questions; transmit the answers to a remote processing system; receive, from the remote processing system, settings determined based on the transmitted answers; and adjust control settings of the system based on the received settings.

Disclosed is a connector for a medical tube, the connector having a first portion having a first opening, a second portion having a second opening, a lumen formed by the first portion and the second portion, the lumen providing a gases flow path between the first opening and the second opening, the first portion of the connector comprises at least one sensor port, the sensor port extending, through a wall of the first portion of the connector into the lumen, the second portion of the connector body may have at least one electrical port, the electrical port configured to provide for electrical connection with at least one wire of the medical tube, and the electrical port is located on the top of the second portion of the connector the first portion is angled with respect to the second portion to form an elbow.

A tub is configured to contain a supply of water and is configured to be inserted into a chamber of a humidifier. The tub includes a tub base configured to contain the supply of water. The tub also includes a tub lid and a flow plate provided between the tub base and the tub lid. The flow plate includes a water level indicator configured to indicate a level of the supply of water in the tub base. In addition, the water level indicator includes a generally rectangular portion and a generally triangular portion.

An apparatus for humidification of air to be delivered to a patient's airways may include a reservoir, and a humidifier chamber. The humidifier chamber may include a humidifier wick and a heating element for heating the humidifier chamber. The humidifier wick may comprise a fibrous sheet material. The humidifier chamber and wick may be vertically oriented in use such that a first end of the wick is above the second end of the wick. A deioniser may be provided to deionise the liquid prior to the humidifier wick. The apparatus may pasteurise liquid to be delivered to the humidification wick.

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.

An apparatus is provided to change the absolute humidity of a flow of air for delivery to an entrance of the airways of a patient, the change being compared to the absolute humidity of ambient air. The apparatus has a reservoir configured to hold a volume of liquid. A heating element creates vapour from the liquid. A chamber is provided to mix the flow of air with the vapour. The apparatus has a body having a first wall structure with a chamber inlet port. A closure element having an air inlet port for pneumatically connecting to a source of the flow of air is secured to the body to provide a sealed gas flow path between the air inlet port and the chamber inlet port, and a liquid trap in the gas flow path.

A method for determining that a patient interface component comprising a vent has been replaced between therapy sessions of treatment of sleep disordered breathing, the method comprising: acquiring or receiving first vent flow rate data representing one or more estimated first vent flow rates of gas through a first vent of a patient interface in use during a first therapy session; acquiring or receiving second vent flow rate data representing one or more estimated second vent flow rates of gas through a second vent of a patient interface in use during a second therapy session after the first therapy session; and identifying, by comparison of the second vent flow rate data to the first vent flow rate data, a difference in resistance to flow through the first vent than through the second vent indicating that the second vent is not the same vent as the first vent.

A patient interface assembly includes a flexible cushion configured to sealingly engage the patient's nares and a frame with a pair of flexible extending members that extend laterally from opposite sides of the frame. The frame and the flexible cushion together form a chamber. The patient interface assembly also includes a positioning and stabilising structure configured to maintain the flexible cushion in engagement with the patient's nares. The positioning and stabilizing structure has a pair of headgear straps. Each headgear strap is connected to a respective one of the flexible extending members. The flexible extending members do not form an airflow path for the breathable gas. The headgear straps have a multi-layered structure, at least one layer being made of fabric and at least one layer being made of plastic. In addition, the at least one plastic layer is a rigidizer that adds rigidity to the respective headgear strap.

A system for providing continuous positive air pressure therapy is provided. The system includes a flow generator, a sensor, and a computing device. The computing device is configured to control operation of the flow generator based on sensor data. The computing device is further configured to display, on a display device, one or more questions relating to demographic and/or subjective feedback; responsive to displaying the one or more questions, receive one or more inputs indicating answers to the one or more questions; transmit the answers to a remote processing system; receive, from the remote processing system, settings determined based on the transmitted answers; and adjust control settings of the system based on the received settings.
