Breathing circuit components for respiratory apparatus

Abstract

In one embodiment, a breathing circuit component is provided and comprises: an inlet; an outlet; and an enclosing wall defining a gases passageway between the inlet and the outlet, at least a region of the wall comprising a membrane that allows the passage of water vapour without substantially allowing the passage of liquid water or respiratory gases, wherein, said membrane has a thickness of about 35 to 45 micrometers.

Description

technical field [0001] The present invention relates to components of breathing circuits for use in breathing apparatus, and in particular to components such as breathing gas tubing. Such breathing gas conduits may include inspiratory or expiratory gas conduits, or portions of such conduits, connected between the flow controller and the patient interface. Such breathing circuit components may include other parts of the breathing circuit, such as tubing connections, tubing adapters, tubing mounts, or shorter sections of breathing gas tubing for connection between the patient interface and the inspiratory gas tubing, The inspiratory gas conduit is used to deliver inspiratory gas to the patient interface. The present invention arose from work related to breathing gas conduits of the type described in our earlier patent applications US 2001054422 and US 20090126817, each of which is hereby incorporated by reference in its entirety. Background technique [0002] In breathing ap...

Problems solved by technology

[0006] Breathing circuit components that include this breathable material may have reduced durability and may be susceptible to damage by the end user

[0007] Prior art breathing gas tubing may also be prone to unwanted noise during use, especially when moving, flexing or bending the breathing gas tubing

This movement may cause a 'rustling' type noise, which is undesirable
