ABSTRACT:
A pulmonary ventilator-bellows-assembly kit includes a base to which a large (adult) cylindrical housing and a small (pediatric) housing, either one of which are mountable and sealable to the same peripheral base portion. Also included are a large bellows mountable directly to the base and a small bellows that is mountable to the base via an adaptor. The cylindrical housings to base mounting means use a bayonet type lock and an O-ring seal so that mounting is simply and easily accomplished by inserting a housing and twisting it over the base. The small-bellows adaptor also seals to the base using an O-ring and the small housing automatically locks it into place. The adaptor is adapted to be stored on the base when the large bellows and large housing are mounted and in use.
