Document Type and Number:

WIPO Patent Application WO/2019/051698

Kind Code:

A1

Abstract:

A ventilator (1), comprising: a first gas path (11), comprising a first pressurized gas source adaptor (110) and a first flow adjustment device (111) connected in that order; a second gas path (12), comprising a second pressurized gas source adaptor (120) and a second flow adjustment device (121) connected in that order; a third gas path (13), comprising a third pressurized gas source adaptor (130); a first inhalation branch (15) for delivering inhalation gas to a patient; a second inhalation branch (16) for delivering inhalation gas to the patient, comprising a gas compression device (160); a switching device (14), comprising a first mixing mode (M1) connecting the first gas path (11) and the second gas path (12) to the first inhalation branch (15), and a second mixing mode (M2) connecting the first gas path (11) and the third gas path (13) to the second inhalation branch (16); and an exhalation branch (20) for managing exhaled air of the patient. The first mixing mode (M1) and the second mixing mode (M2) are switchable to provide mixed gas with a desired oxygen concentration without depending on a central gas supply system.
