NASAL CONTINUOUS POSITIVE AIRWAY PRESSURE DEVICE FOR LOWERING PATIENT WORK-OF-BREATHING

摘要

A nasal continuous positive airway pressure device for lowering patient work-of-breathing comprising: an inspiratory tubing in fluid communication with at least two nasal prongs; expiratory tubing; and a generator body coupled there between, the generator body comprising: at least two jets configured for receiving gas from the inspiratory tubing; and a flow enhancer configured for directing received gas, the flow enhancer comprising: a gas manager configured for channeling received gas towards a jet impingement point via at least two jet paths; a fluidic flip trigger configured for triggering a fluidic flip of channeled gas back towards the expiratory tubing by directing a first portion of exhaled patient breath towards the jet impingement point along a first pathway; and an isolated pathway manager configured for directing a second portion of the exhaled patient breath along a second pathway towards the expiratory tubing, the second pathway isolated from the first pathway.
