ABSTRACT:
A throat and esophagus clearing device includes an elongated object receiving chamber with a trigger housing attached thereto. The trigger housing includes a trigger operably responsive to a compression spring and in operable communication with a diaphragm or piston wherein the operation of the diaphragm or piston creates a negative pressure in the elongated object receiving chamber thereby producing a pressure differential, when in use, across an object lodged in a victim's air passageway.
