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.
