Scavenger system for anesthesia circuits

摘要

A scavenger system for anesthesia circuits having a breathing bag and an escape passageway in said bag, a pair of telescoping tubular components having slots therein and being rotatable to vary the opening created by the alignment of said slots, and a laterally extending parabolic conduit terminating in an enlarged areating chamber in which a vacuum is maintained to draw the gas out of said chamber without placing a negative pressure on the escape passageway.
