A device mouthpiece is provided wherein the mouthpiece comprises a cylindrical tube and a filter element, wherein the filter element comprises a frame and a filter medium secured to the frame; the frame defines an annular channel which receives therein an end portion of the cylindrical tube; the end portion of the cylindrical tube forms a friction fit within the annular channel; and wherein the filter element is secured to the cylindrical tube via the friction fit.

System for assisting a patient in speaking, comprising at least one ventilation apparatus and a patient interface, the ventilation apparatus comprising at least one controllable respiratory gas source and being designed to identify two or more respiratory phases, at least inspiration and expiration, of the patient, and the patient interface having at least one speaking tube and a respiratory tube and being configured to conduct speaking gas to the patient via the speaking tube and to conduct respiratory gas to and/or from the patient via the respiratory tube. The system is configured to provide speaking gas to the patient at least temporarily in a speaking mode in order to enable speaking.

A patient interface for supplying a flow of breathable gas to the airways of a patient may comprise a heat and moisture exchanger (HME). The HME may be positioned in a flow path of the flow of breathable gas. The HME may absorb heat and moisture from gas exhaled by the patient and the incoming flow of breathable gas to be supplied to the patient's airways may be heated and moisturized by the heat and moisture held in the HME.

A method of delivering a substance, such as one or more of a triptan, a nasal steroid or carbon dioxide gas, to the nasal cavity of a subject, in particular for the treatment of headaches, for example, migraine, or rhinosinusitis, for example, chronic rhinosinusitis, optionally with polyps, the method comprising the steps of fitting a nosepiece to one nostril of the subject, delivering the substance through the nosepiece to the posterior region of the nasal cavity of the subject.

A cushion assembly for a patient interface includes an elastomeric seal-forming portion with a dome-shaped superior region that is intersected by the sagittal plane in the vicinity of a superior tangent point. The seal-forming portion further including a saddle-shaped inferior region that is intersected by the sagittal plane and includes an inferior tangent point. A first support region is located on one side of the sagittal plane between the inferior region and the superior region, the exterior surface of the elastomeric seal forming portion at the first support region being cylinder-shaped and/or saddle-shaped. In addition, a blowout prevention system is configured to counter a force acting on the unsupported edge of the elastomeric seal-forming portion due to a pressure within the chamber, the blowout prevention system being attached to the elastomeric seal-forming portion at the first support region of the elastomeric seal-forming portion.

A connection assembly for a respiratory therapy system, comprising: an outlet assembly, said outlet assembly including an outlet housing and a swivelling disc located on said outlet housing, said outlet housing and said swivelling disc defining, at least in part, a recess; an outlet connector located at an end of a tube portion, said outlet connector including an electrical connector; and a cable having a first end to connect to the electrical connector and a second end to connect to at least one electrical component of the respiratory therapy system, said cable having a slack portion, wherein said outlet connector and said swivelling disc are rotatable in unison between a first position and a second position, and wherein the slack portion of the cable extends from the recess and wraps around the swivelling disc as the swivelling disc is rotated from the first position to the second position.

The present technology relates to systems and/or methods for enabling a respiratory device to be configured when a clinician or healthcare professional is remote from the respiratory device. One form provides a method of configuring a respiratory device, the respiratory device comprising a processor configured to control operation of the respiratory device in accordance with a plurality of operating parameters. The method comprises determining a combination of settings for the device from an identifier sent to the device, the identifier corresponding to the combination of settings, and configuring the respiratory device accordingly. Another form provides a method of verifying the configuration of the respiratory device by outputting an identifier corresponding to the combination of settings for the device, and determining the settings from the identifier.

A respiratory pressure therapy system for providing continuous positive air pressure to a patient via a patient interface configured to engage with at least one airway of the patient. The system includes: a flow generator configured to generate supply of breathable gas for delivery to the patient via the patient interface; at least one sensor; a display; and a computing device. The computing device is configured to: receive sensor data that is based on measured physical property of the supply of breathable gas; control, based on the received sensor data, the flow generator to adjust a property of the supply of breathable gas; receive, an input indicating assistance is needed with using the patient interface; receive one or more images of the patient with the patient interface; analyse the received one or more images; and based on the analysis, display instructions for positioning the patient interface.

A sedation device has a housing divided internally into a ventilator chamber and an associated evaporator chamber which overlap and are separated by a filter mounted between the chambers and forming a common gas-permeable dividing wall between the chambers. An inlet port is provided at one end of the ventilator chamber at a top of the housing for connection to a patient ventilator in use. An outlet port on the evaporator chamber can be connected via a breathing tube to a patient. An evaporator is mounted within the evaporator chamber for delivery of a volatile sedative into the evaporator chamber during use.

A blower of a CPAP device is housed inside a main body case of a CPAP device. The blower is roughly divided into a fan unit housing a fan therein, and a delivery tube, through which air sent from the fan passes. In the main body case, a first support member, a second support member, and a third support member are interposed between the main body case and the fan unit to support the fan unit. When viewed from a rotation axis of the fan, the first support member and the second support member are disposed to pinch the blower on the side of a connection point between the fan unit and the delivery tube relative to the rotation axis, and the third support member is located on the opposite side to the connection point between the fan unit and the delivery tube relative to the rotation axis.
