Breathing device

Abstract

A breathing device for assisting patients to breathe by maintaining positive airway pressure during the breathing cycle comprises, in fluid communication, a breathing channel ( 2 ) and an exhaust channel ( 4 ) extending from a junction therebetween. A gas inlet channel ( 8 ) is arranged, so as in use, to introduce gas into said breathing channel ( 2 ). A positive pressure may be maintained in the breathing channel ( 2 ), wherein the axis of said gas inlet channel ( 8 ) is laterally offset ( 10 ) at the point at which the gas inlet channel ( 8 ) introduces the gas into the breathing channel ( 2 ) from the axis of the narrowest part of the breathing channel ( 2 ).
