Circuit kit for a humidifier

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

A patient interface assembly has a patient interface and a securement system for the patient interface and/or patient interface tubing. The patient interface has a body and at least one nasal prong extending from the body. The at least one nasal prong has a gas inlet for fluid communication with a supply of breathable gas, and a gas outlet configured to direct a flow of gas towards a nare of the user's nose. The at least one nasal prong further includes an exterior surface, at least a portion of the exterior surface is a sealing surface configured to seal the nare of the user's nose. The securement system has a two-part releasable attachment or connection arrangement, the arrangement comprising a first patch and a second patch.

Nasal cannula and securement system

A humidification system can include a heater base, a chamber, and a breathing circuit. The heater base includes a heater plate positioned in a recessed region, and a heat conductive portion of the chamber is configured to contact the heater plate. The heater base includes a guard configured to control movement of the chamber into and out of the recessed region. The guard includes an anti-racking mechanism. The chamber includes an inlet port, an outlet port. A downward extension extends into the chamber from the inlet port, and a baffle is disposed at a lower end of the downward extension. A component of the breathing circuit can include a conduit hanging end cap for shipping and storage. The end cap can include a hanging component to allow the breathing circuit component to be hung from a medical stand. The system can detect when breathing circuits are connected in reverse.

Humidification system

A breathing circuit for use in respiratory therapy includes an inspiratory tube and an expiratory tube. The inspiratory tube of the breathing circuit has a smooth bore. The expiratory tube of the breathing circuit is corrugated. Preferably, the expiratory tube is vapor permeable. Using the combination of a smooth bore inspiratory tube with a corrugated expiratory tube has the unexpected result of improving the performance of the breathing circuit and its components.

Medical tubes for breathing circuit

A humidification system for delivering humidified gases to a user can include a heater base, humidification chamber having an inlet, outlet, and associated fluid conduit, and breathing circuit including a supply conduit, inspiratory conduit, and optional expiratory conduit. The humidification system can include various features to help make set-up less difficult and time-consuming. For example, the supply conduit, inspiratory conduit, and optional expiratory conduit can be coupled into a one-piece circuit to aid set-up. Various components can be color-coded and can have corresponding structures to indicate which components should be connected to one another during set-up. Such features can also help make the set-up process more intuitive for an operator, which can reduce the need for specialized training and reduce the number of potential errors.

Usability features for respiratory humidification system

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 bypass adaptor for a respiratory assistance system including an inlet connector configured to connect to a gases source outlet and defining a first gases passageway with a first axis and an outlet connector configured to connect to an inspiratory conduit connector and defining a second gases passageway with a second axis, the second gases passageway being fluidly connected to the first gases passageway, the inspiratory conduit connector being incompatible with direct connection to the gases source outlet, wherein the first axis is separated from the second axis by an angle that allows the inspiratory conduit connector to be connected via the bypass adaptor to the gases source outlet in a space smaller than the length of the inspiratory conduit connector. Also provided are a port cap assembly and a humidifying apparatus including the port cap assembly, wherein the port cap assembly provides for improved assembly and/or usability.
