Abstract
This invention relates to a humidifier for a respiratory assistance device, a respiratory assistance device comprising a humidifier and related methods and apparatus. The invention particularly provides arrangements for generating vapour by impinging light on metallic and/or carbon based material, particularly in the form of nanoparticles.
Claims25
A heater for a respiratory assistance device, the heater comprising:
- a heater body;
- a metallic or carbon-based material that is integral to or coupled to the heater body;
- the heater body comprising at least one surface that is configured to come into contact with, or in proximity to, a fluid used by the respiratory assistance device, in use;
- and
- the heater being configured such that, in use, at least a portion of the metallic or carbon-based material is exposed to light such that light impinges on the metallic or carbon-based material to generate localised heating of the fluid to generate vapour for use by the respiratory assistance device, and the heater being configured such that vapours can be prevented from being generated when not required.

A respiratory assistance device comprising:
- a humidifier;
- a heater comprising a metallic or carbon-based material, the heater also comprising a heater body, the metallic or carbon-based material being integral to or coupled to the heater body, the metallic or carbon-based material being configured to be impinged by light, in use, at least one surface of the heater body being configured to come into contact with, or in proximity to, a fluid used by the respiratory assistance device, in use, and the heater being controllable so as to prevent generation of vapours when not required;
- a gas source coupled or configured to couple to the humidifier;
- and
