Nasal cannula assembly

A patient interface, such as a nasal cannula, including a body to be positioned upon a user (preferably such as a user's face), the body including at least one (and preferably a pair of) nasal prong(s), the or each nasal prong including a lumen capable of being fluidly connected thereto for fluid communication with a supply of breathable gas, the or each nasal prong to be in a configuration either inserted into, or to direct a flow of gas toward, a nare or the nares of the user's nose, wherein the body includes at least one element responsive to force(s) or movement(s), or both, experienced by at least a first region of the patient interface.

Patient interface

The disclosure relates to a nasal cannula comprising a port configured for delivery of a medicament into a flow of a fluid being delivered by the nasal cannula to a user and/or configured for interfacing with a medicament delivery device or an instrument. The disclosure also relates to a nasal cannula comprising an asymmetric profile to reduce an amount of occlusion of one nare of a user to provide access for an instrument to the nare with the nasal cannula in use.

Nasal cannula

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.

Apparatus for use in a respiratory support system

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 system includes a first patient interface for delivery of a flow of gases to a patient, a second patient interface for delivery of a second flow of gases to the patient, and a device that switches the system between a first respiratory mode and a second respiratory mode. In the first respiratory mode, the flow of gases are delivered to an outlet of the first patient interface when the second patient interface is absent from the patient. In the second respiratory mode the device reduces or stops delivery of the first flow of gases to the outlet of the first patient interface when the second patient interface is located together with the first patient interface upon the patient.

User interface and system for supplying gases to an airway

A user interface convertible between a nasal configuration and an oral configuration. The user interface has a nasal cannula and a mouthpiece. The nasal cannula has a body portion and at least one prong extending from the body portion, the prong being adapted to direct a flow of gas into a nare of a user's nose. The mouthpiece is adapted to engage the mouth of the patient and direct a flow of gas into a user's mouth. In the nasal configuration the prong of the nasal cannula is adapted to direct a flow of gases into a nare of the patient. In the oral configuration, the nasal cannula is engaged with the mouthpiece such that a gases flow is provided to at least the mouth of the user.

User interface for supplying gases to an airway

This invention relates to, among other embodiments, methods and apparatus/systems for controlling gases delivery to a patient, such as via a patient interface. Such methods comprising receiving an input relating to either a patient's breathing phase and/or another patient parameter, controlling a flow of gases to be delivered to the patient and the inclusion in said flow of gases of a supplementary gas, wherein the amount of supplementary gas provided to the patient is substantially synchronized with respect to the patient's breathing phase and/or another patient parameter.

Apparatus for controlling gas delivery to a patient

Tube assembly and connector

The present disclosure relates to determining a corrected exhaled gas measurement during high flow respiratory therapy. Measuring exhaled gas concentration during high flow respiratory therapy is difficult and inaccurate due to a phenomenon known as flushing. The high flows delivered to the patient flush the dead space in the conducting airways, which causes a dilution effect that results in underestimated or overestimated exhaled gas measurement depending on the gas composition delivered by the high flow system. This can lead to incorrect clinical measurements and diagnoses. Various algorithms are disclosed herein to account for the dilution effect caused by flushing, allowing for the method of measuring gas concentrations to still be used accurately for clinical measurements.

Exhaled gas measurement compensation during high flow respiratory therapy

A nasal cannula arrangement for use as part of systems for delivery respiratory gases to a patient is disclosed. The nasal cannula arrangement includes a manifold part adapted to receive gases from a delivery conduit. The manifold includes one but preferably a pair of prongs extending upward and curving towards the rear of the manifold. The prongs are inserted into the nostrils of the patient and deliver gases to a patient. The prongs have a cut out on the rear side of the prongs. The cut out forms a gases outlet in the prongs and are shaped such that the area of the cut out area is greater than the cross sectional area of the prongs at the entry point to the prongs.

Several methods of supporting respiratory function of a patient before, during and/or after a medical procedure are disclosed. In certain arrangements, supporting respiratory function while a patient is under general anaesthesia can include providing a high gas flow a high gas flow that is greater than 15 L/min while the patient is under general anaesthesia. In certain arrangements, a method of providing ventilation while a patient is under general anaesthesia involves providing only a gas flow delivered through a nasal interface that is greater than 15 L/min while the patient is under general anaesthesia.

Methods and apparatus for high gas flow

Connector for a respiratory system conduit

There is provided a a respiratory gas delivery and sampling system, a gas sampling system, a gas sampling interface and a gas sampling tip that may be used to sample exhaled and/or expired gases from a patient, particularly from a patient who is apnoeic and/or who is receiving high flow respiratory therapy. The gas sampling system comprises a respiratory gas monitor in fluid communication with the gas sampling interface, which comprises the gas sampling tip of the invention. The gas sampling interface comprises a gas sampling conduit and the gas sampling tip is located at a free end of the conduit. The gas sampling interface may be configured to allow the gas sampling tip to be selectively positioned at or in the mouth or a nare of the patient's nose.

Breath sampling interface

The invention relates to a respiratory system comprising a first patient interface for delivery of a first flow of gases to a patient, a second patient interface for delivery of a second flow of gases to the patient, and a device and/or sensing arrangement that is configure to facilitate a switching of the system between a first respiratory mode where the device allowing delivery of the first flow of gases to an outlet of the first patient interface when the second patient interface is absent from the patient, and a second respiratory mode where the device reducing or stopping delivery of the first flow of gases to the outlet of the first patient interface when the second patient interface is located together with the first patient interface upon the patient.
