ABSTRACT:
This invention relates to an apparatus and method for adapting an existing air pump to also include a source of vacuum emanating from the same pump. An adapter plate is secured onto the face of the pump from which an outlet protrudes and an air intake is located. The plate is provided with ports in line with the output and intake openings in the face of the pump and such openings accommodate fittings of various pre-selected sizes to provide air pressure and vacuum for use in the field of respiratory needs of a patient. The ordinarily used input of atmospheric air entering the pump through an opening in the face of the pump is thereby converted to a vacuum source in the application to a patient of an aspirator unit, and the like.
