Abstract: An apparatus-and method for removing a lodged mass from an airway of a human or animal in which the source of suction is a sealed vacuum container which is punctured when the device is positioned within the mouth of the victim. As contrasted with prior art devices of this types the retracting force created due to the pressure differential is developed instantaneously to a greater degree than heretofore obtainable, and this force is maintained until the foreign object is completely dislodged.

Abstract: A vacuum device for removing a lodged mass or bolus from the throat of a choking victim. The device includes a pump for creating a vacuum chamber communicating with a mouthpiece having a frangible membrane. A resilient striker fractures the membrane to generate a substantially instantaneous vacuum to the mouthpiece to dislodge the mass. In one embodiment, the membrane is substituted by a manually displaceable sealing member, which is resealed after use of the device by movement of a vacuum-generating plunger.

Abstract: A device for removing a mass lodged in a choking victim's throat comprises a manifold, piston, spool, and latch. The manifold has first, second, and third conduits in selective fluid communication with each other, with the second conduit terminating in an orifice in a mouthpiece. The spool, having a transverse orifice, may be disposed in the third conduit, slidable between a first position where the orifice permits fluid communication between the first and second conduits, and a second position where the spool blocks fluid communication. The piston is slidably disposed within the first conduit, and with the spool is in the second position, the latch is usable to secure the piston relative to the manifold at one or more discrete positions to create a measured amount of vacuum pressure in the first conduit. The vacuum pressure is transmitted to the mouthpiece by movement of the spool to said first position.

Abstract: A method of removing obstructions lodged in the pharnyx and/or larnyx of a victim, including the steps of providing a suction device incorporating a rigid hollow tongue depressor having suction means at a free end thereof; inserting said tongue depressor to a point wherein the free end is adjacent an area in which the obstruction is located; applying suction to the free end to dislodge the obstruction and retain it on the free end, and maintaining the suction while withdrawing the tongue depressor and the obstruction engaged thereon.
