A breathing assistance apparatus and method of controlling a breathing assistance apparatus is disclosed. Particularly, the breathing assistance apparatus is controlled such that it has a drying cycle to enable drying of the tubing that supplies gases to a user and prevent the harbouring of pathogens within the tube. The drying cycle is preferably operated automatically by internal controllers in the apparatus. However, it may be manually activated by pressing a button on the apparatus. The drying cycle is preferably activated at the end of a user's treatment session.

Breathing assistance apparatus

A respiratory assistance apparatus is configured to provide a heated and humidified glow of gases and has a control system that is configured to detect a fault in the flow path. A flow path is provided for a gases stream through the apparatus from a gas inlet through a blower unit and humidification unit to a gases outlet. A flow rate sensor is provided in the flow path and is configured to sense the flow rate and generate an flow rate signal and/or a motor speed sensor is provided that is configured to sense the motor speed of the blower unit and generate an indicative motor speed signal.

Flow path fault detection method for a respiratory assistance apparatus

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.

Respiratory assistance apparatus

The present disclosure provides to graphical user interfaces for controlling a flow therapy apparatus. The graphical user interface can provide a display of flow therapy treatment information and indicators of a patient's health. The graphical user interface can be configured to display the information associated with the patient on one or more user interface screens.

Graphical user interface for a flow therapy apparatus

A support apparatus for a breathing assistance apparatus has a base, a mount, and a handle. The mount is configured to releasably couple the support apparatus with the breathing assistance apparatus by lowering the breathing assistance apparatus relative to the mount. The handle is configured to enable the support apparatus and a releasably coupled breathing assistance apparatus to be lifted and carried by a user.

Support for a breathing assistance apparatus and/or accessories

A connector is used to connect a gases supply to a user. The user can be fitted with an interface, such as a cannula, while the gases supply can include a conduit. The connector interfaces between the conduit and the interface. The connector has a female assembly and a male assembly that connect together, such as by push fit. The male assembly includes an inner portion sized and configured to mate with a first female connector and an outer portion sized and configured to alternatively mate with a second female connector.

Connector for multiple sized connections

The breathing assistance apparatus of the present invention includes a manifold that is provided with or retrofittable to gases supply and humidifying devices. The manifold allows gases from an oxygen concentrator to be combined with the flow through a gases supply and humidifying device, most usually air. The combined output of oxygen and other breathing gases (air) is then humidified. The breathing assistance apparatus and manifold of the present invention provides a safe method to add oxygen to the input air stream of a gases supply and humidifying device and reduces the amount of accumulation of oxygen within the gases supply device, reducing fire risk should sparking occur within the device.

Breathing assistance apparatus with a manifold to add auxiliary gases to ambient gases

A respiratory mask or other sealing interface can be used in combination with a nasal cannula or other unsealing interface in providing respiratory therapies for the treatment of COPD or OSA. The mask can act as a pressure vessel over the top of a nasal cannula, with the intention of increasing expiratory pressure whilst allowing the nasal cannula to provide a user with breathing gases of a high humidity and temperature. The ability to selectively apply increased expiratory pressure may be effective in reducing a user's breathing rate and thus beneficial in the treatment of respiratory distress.

Pressurizing masks, systems and methods

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.

A method of controlling a flow rate of gases supplied to a patient by a respiratory assistance device includes controlling the supply gases flow rate so as to deliver gases to the patient according to a predetermined gases pressure/flow rate profile for at least a portion of the breathing cycle. A profile may be achieved that provides the patient with a particular benefit or therapy.

Respiratory assistance device and a method of controlling said device

Patient interfaces for respiratory therapy in the form of nasal interfaces or nasal masks include features that enhance or provide lateral stability of the interface. At least some of the embodiments provide multiple facial contact points or areas located in the general areas of the user's cheeks and/or upper lip. Some embodiments of the nasal interfaces provide advantageous sealing characteristics. The nasal interfaces may provide a controlled expiratory flow to reduce noise. Some embodiments include nasal pillows instead of or in addition to nasal prongs. The nasal pillows can have exhaust vents or can change in length in response to a pressure level within the nasal pillow.

Nasal interfaces for respiratory therapy

The invention comprises a method of operating a breathing apparatus comprising measuring a baseline breath flow parameter being respiratory rate and/or tidal volume or a parameter derived therefrom, varying the flow rate provided by the breathing apparatus, measuring a current breath flow parameter being respiratory rate and/or tidal volume or a parameter derived therefrom, comparing the baseline and current breath flow parameters, and altering operation of the breathing apparatus based on the comparison. The invention also comprises a breathing apparatus that implements the above method.
