A filter for an apparatus for delivering a flow of gas, the filter comprising: a filter body, wherein the filter body has a main compartment and a sub-compartment at least partly within the main compartment, wherein the main compartment is in fluid communication with a main compartment gases inlet and the sub-compartment is in fluid communication with a sub-compartment gases inlet; and a filter medium associated with both the main compartment and the sub-compartment, and that is arranged to filter gases in, or exiting, the main compartment and the sub-compartment.

Valve module and filter

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 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.

Breathing assistance apparatus

Patient interface connector

The gases temperature supplied to a patient when the patient is undergoing treatment such as oxygen therapy or positive pressure treatment for conditions such as Obstructive Sleep Apnea (OSA) or Chronic Obstructive Pulmonary Disease (COPD) is often measured for safety and to enable controlling of the humidity delivered to the patient. The invention disclosed is related to measurement of properties, particularly temperature (thermistor), of gases flowing through a heated tube, supplying gases to a patient, which utilises the heating wire within the tube.

Apparatus for measuring properties of gases supplied to a patient

This invention relates to headgear and a patient interface, or components of a headgear or patient interface, such as a nasal cannula. In one embodiment is a size adjustable headstrap to be provided as a headgear or a part thereof, in another is a portion of a headstrap or component for association therewith in which the portion or component facilitates improved location of the strap upon a user's face, in another embodiment is a system for encapsulating or covering a connector from contact with a user's face or facial skin, in another embodiment is a face mount part or body for a patient interface of a particular configuration, and in yet a further embodiment is a gases flow manifold for delivering of gases to a patient interface of a particular configuration for improved patient comfort.

Patient interface and headgear for a respiratory apparatus

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.

Fluid mixing structure

A breathing assistance system for delivering a stream of heated, humidified gases to a user, comprising a humidifier unit which holds and heats a volume of water, and which in use receives a flow of gases from a gases source via an inlet port, the flow of gases passing through the humidifier and exiting via an exit port, the system further having a temperature sensor which measures the temperature of the gases exiting the humidifier unit, an ambient temperature sensor which measures the temperature of gases before they enter the humidifier unit, and a flow sensor which measures the flow rate of the gases stream, the system also having a controller which receives data from the temperature and flow sensors, and which determines a control output in response, the control output adjusting the power to the humidifier unit to achieve a desired output at the humidifier unit exit port.

Control of humidifier chamber temperature for accurate humidity control

A respiratory assistance apparatus () is provided, adapted to deliver gases to a user or patient (). The apparatus () comprises a housing () provided with a chamber () and a heater (), the chamber () comprising at least one gas port () connected to, or arranged to be connected to, at least one intermediate passageway (). The apparatus () is operative according to a disinfection mode of predetermined profile in which the heater () heats liquid in the chamber () to produce vapour at or above a target dewpoint temperature and/or humidity level. The apparatus () is arranged such that the vapour is delivered to the intermediate passageway () to disinfect the intermediate passageway () with moist heat throughout a predetermined duration of the disinfection mode. Associated attachments and methods are also provided.

An apparatus for delivering a flow of gas, has a housing' with a recess, and an outlet port&#x2032; for a flow of gas. The recess is defined by at least one wallthat is substantially continuous, gas impermeable, and unbroken, other than a gasflow passage from the recess to the outlet port of the housing.
