Another embodiment comprises a patient interface itself comprising a backing for positioning on a patient's face, a dermal patch having a patient side and an interface side, the patient side of the patch attachable to the user, the patch comprising at least a first flap portion attachable to the tube for affixing the tube to the patch, a two-part releasable connection arrangement for releasably securing the patient interface to the patch.

Abstract: A method of estimating a parameter indicative of respiratory flow of a patient being administered flow therapy, comprising: optionally administering a gas at a flow rate to the patient using a flow therapy apparatus with a patient interface, determining a terminal pressure in, at or proximate the outlet of the patient interface or in, at or proximate the nares of the patient, determining nasal RTF, determining a nasal flow parameter being or indicative of nasal flow based on the pressure and a nasal RTF, and optionally outputting the nasal flow parameter or parameter derived therefrom.

Abstract: High flow therapy is used to treat Cheyne-Stokes respiration and other types of periodic respiration disorders by periodic application of high flow therapy, adjustment of high flow therapy flow rates and/or periodic additions of CO2 or O2 into the air flow provided to the patient.

Abstract: 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.

Abstract: A mask assembly can include a mask seal. In some configurations, the mask assembly can be configured to be fully positioned lower than a bridge of a nose of a face of a user and to provide an exposed bridge of the nose of the user. The mask seal can comprise a nasal region comprising at least one nasal opening, a first paddle on a first side of the nasal region and a second paddle on a second side of the nasal region. The first paddle is configured to contact one side of the nose of the user and the second paddle is configured to contact the other side of the nose of the user.

Abstract: An apparatus or kit for a respiratory support system for delivering humidified gas to a user or patient. The apparatus comprising a humidifier chamber in pneumatic communication with a gases source, an inspiratory conduit in pneumatic communication with the humidifier chamber downstream of the humidifier chamber, a filter that is in pneumatic communication with the inspiratory conduit downstream of the inspiratory conduit, and a patient interface for delivering humidified gas to a user or patient, wherein the patient interface is in pneumatic communication with the filter downstream of the filter, or is configured to be placed in pneumatic communication with the filter downstream of the filter.

Abstract: Data related to the adherence of a patient to a therapy regime can be collected from multiple medical devices, each of which may have an incomplete data set with data entries associated with times. Each incomplete data set represents a portion of a complete data set. The data sets can be integrated to create a complete data set with data entries from each incomplete data set being arranged in a temporal sequence with respect to one another. A report may be generated, the report having the data entries of the complete data set or a function of the data entries of the complete data set.

Abstract: The present invention relates to a tracheal coupling comprising a patient port 33, an outlet port 36, an inlet port 31 between the patient port and the outlet port, such that flow 34 from the inlet port can go to the patient port or direct to the outlet port, and a flow restriction e.g. 32 between the inlet port and the outlet port, or at the outlet port.

Abstract: This invention relates to a surgical smoke evacuation system for use in removing gases and smoke created in surgical procedures form within an insufflated surgical cavity, Such a system comprises a discharge assembly adapted to form a gases path, and having an end which in use is located within said surgical cavity so that gases and/or surgical smoke inside said cavity can pass out of said cavity and through said discharge assembly along said gases path, a flexible discharge limb having an operational site end and an outlet end, and a self-supporting wall defining a gases flow passage between said operational site end and said outlet end, in use said open operational site end sealingly connected to said discharge assembly so that said gases and/or surgical smoke can pass out of said discharge assembly and into said discharge limb, a filter connected in use to the outlet end of the discharge limb, at least part of said wall of the discharge limb formed from a breathable material, said breathable material allow

Abstract: An adaptor for a respiratory assistance system delivers aerosols to a patient. The adaptor is lightweight with a small footprint to increase patient comfort. The adaptor has a nozzle and a sealing mechanism to maintain pressure therein regardless of whether the nozzle is inserted into the adaptor. The adaptor is configured to connect to medical tubing and a medicament delivery device.

Abstract: The present disclosure provides for an improved method of determining a water out condition in a humidified gases supply apparatus. The method includes a two-step process including a primary determination of a water out condition and a secondary determination of a water out condition. This primary determination is made during observation of the normal operation of the apparatus. During the secondary determination the method takes temporary control over the humidifying part of the apparatus. The secondary determination confirms or contradicts the primary determination.

Abstract: A method of estimating respiratory demand of a patient being administered flow therapy can include: administering a gas flow rate to the patient through both nostrils using a flow therapy apparatus with a patient interface for each nostril, measuring a parameter associated with that nostril, the parameter being one or more of: respiratory demand of that nostril, indicative of respiratory demand of that nostril, or a parameter from which respiratory demand of that nostril can be derived, determining respiratory demand (or parameter indicative of respiratory demand) for the patient from the nostril parameter for each nostril.

Abstract: A gases humidification system includes a measuring chamber and a mixing chamber. The mixing chamber has one or more mixing elements that improve a mixing of gases before reaching the measuring chamber. Ultrasonic sensing is used to measure gases properties or characteristics within the measuring chamber. A baffle or a vane may be used to control and direct the gases flow through the mixing chamber as the gases flow moves into the measuring chamber.
