WIEDERBELEBUNGSGERAET MIT EINEM DIE STROEMUNGSRICHTUNG KONTROLLIERENDEN VENTIL MIT EINEM INNEREN PEEP-JUSTIERVENTIL

摘要

The directional control valve housing in a squeeze bag resuscitator includes a duck-bill element which permits inhaling from the bag as the duck-bill opens, and spontaneous exhaling as the periphery of duck-bill is pushed away from its seat. An adjustable spring urges the periphery against its seat with force established by the PEEP setting. The housing is in two screwed-together parts and the PEEP setting is effected by screwing the parts inward or outward.
