Ventilation mask with integrated piloted exhalation valve

摘要

The disclosure is directed to various tubing arrangements and an associated Y-connector which may be used to facilitate the operative interface of the mask to a ventilator within a ventilation system. The tubing arrangement may comprise a pair of bi-lumen tubes. One end of each of the bi-lumen tubes is fluidly connected to the mask, with the opposite end being fluidly connected to the Y-connector. The Y-connector is in turn fluidly connected to one end of either a tri-lumen tube or a quad-lumen tube also included in the tubing arrangement, the opposite end of such tri-lumen tube or quad-lumen tube being fluidly connected to the ventilator. The Y-connector is uniquely configured to fluidly connect certain lumens of the tri-lumen tube or the quad-lumen tube to dedicated, corresponding ones of the lumens included in respective ones of the bi-lumen tubes, and to further allow for the selective detachment of the tri-lumen tube or the quad-lumen tube from the bi-lumen tubes.
