Abstract
Abstract An aspiration and respiration apparatus including a unit comprising first and second conduit means, means for connecting each of said conduit means to a single source of pressurized gas, and means for controlling the flow of pressurized gas through each of said conduit means. The first conduit means includes a pair of openings, an inlet disposed intermediate said openings, and means for forming during flow of gas therethrough a zone of reduced pressure, said latter means being disposed intermediate said inlet and a first one of said openings. Each of the first and second conduit means is constructed for connection to a corresponding one of a pair of tubes each of which is adapted to have one end thereof disposed in a trachea of an air-breathing vertebrate whereby pressurized gas and a suitable medication may be introduced into the trachea through said second conduit means and one of the tubes, and whereby matter may be removed from the trachea by the other one of the tubes as a result of the flow of pressurized gas through said inlet into said first conduit means, through said means for forming a zone of reduced pressure and out of said first one of said openings. The apparatus as described may also include means for closing the first one of said openings and said first conduit means for causing the inflation of the respiration system of a vertebrate for overcoming hypoxia. Additionally, the first one of said openings is constructed to be closeable by the hand of an operator for causing the inflation of the respiration system. The apparatus of this invention may also include a face mask means for enclosing the nasal and oral openings of an air-breathing vertebrate. The apparatus of this invention may also include a means connected to the second conduit means for injecting liquid into at least a portion of said second conduit means and thus function as an irrigator. The apparatus of this invention may also be used in a combination with a catheter to assist in removal of various fluids from the organs of animals.
