An apparatus to remove an obstruction from the trachea of a choking victim comprises a hollow cylinder having a forward end. A piston is movably disposed within the cylinder and forms a chamber at the forward end of the cylinder. The piston is movable by means of a compressed spring disposed within the chamber of the cylinder. A mask is connected to the cylinder and adapted to form a seal around the mouth of the victim. An airway leads from the chamber to the mask. In use, the mask is placed over a choking victim\s mouth and the spring is released causing rearward movement of the piston. This expands the chamber and reduces the pressure within the chamber and person\s mouth, thereby drawing the obstruction out of the trachea.

A device for dislodging an object from the trachea of a person comprising: a hollow cylinder having a forward end wall with an aperture therein; a piston disposed within the cylinder forming a chamber at the forward end of the cylinder, said piston being moveable along the length of the cylinder between forward and rearward positions; means for biasing the piston rearwardly to expand the size of the chamber; means for releasably maintaining the piston in its forward position; means for stopping rearward movement of the piston at preselected positions along the length of the cylinder; a mask positionable against the face of a person and adapted to form a seal around the person\s mouth, said mask being connected to the forward end wall; and an airway extending from the aperture through the interior of the mask.
