Humidifier heaterbase

Breathing tube

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 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

Connector for a respiratory system conduit

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.

A circuit connector for a humidification system, the system comprising a base unit configured to be engaged by a humidification chamber. The circuit connector comprises an inlet to fluidly connect to an outlet of the humidification chamber to receive humidified gases therefrom, an outlet to sealably connect to or integral with a conduit for directing the humidified gases to a user, and an electrical terminal for electrically coupling the circuit connector to an electrical terminal associated with the base unit. The circuit connector may be releasably and lockably connectable to the outlet of the humidification chamber and/or orientation features may control orientation of component parts of the system as they are assembled.

Humidification system connections

A humidification system can include a heater base, a humidification chamber, and a breathing circuit. A cartridge can be removably coupled to the heater base. The cartridge can include various sensors, probes, sensor wire connectors, heater wire connectors, and/or other features. The cartridge can include features configured to mate with corresponding features on the humidification chamber and the heater base. The cartridge includes a memory, such as an EEPROM, or other suitable storage device. When the cartridge is installed on the heater base, the memory is electrically connected to a processor and/or memory of the heater base. Various models of cartridges can be produced for use with different humidification chambers, breathing circuits, and/or therapies. A connector can be configured to couple an inspiratory conduit to an outlet port of the humidification chamber. The connector can provide a pneumatic connection to the outlet port and an electrical connection to the cartridge.

Connections for humidification system

Valve assembly

A conduit with a collapsible portion, and a nasal interface for providing a flow of gases to a user, is described. The interface comprises a manifold and at least one nasal prong or an outlet extending from the manifold to be received by a user's nare. A side member extends from each side of the manifold, each side member comprising a collapsible portion comprising a lumen. In an open configuration the lumen remains open and in a closed configuration the collapsible portion is pinched or flattened to occlude or substantially occlude the lumen. At least one of the side members is a conduit for a flow of gases from an inlet of the patient interface to the manifold.
