Device for removing a lodged mass

摘要

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.

1. A device for vacuum removal of a lodged mass from the throat of a victim, comprising: a first generally cylindrical tube having first and second ends defining a continuous bore, said first end having means for selectively engaging a mouthpiece element in substantially leak-proof relation; a id="REI-00003" date="20150602" resilientid="REI-00003" striker element positioned within said second end of said first tube selectively maintained in relatively cocked position by a manually operable means; a laterally-extending vacuum pump element including a second tubular member having a first end communicating with said first cylindrical tube and a second open end defining a bore, including a recess at a second end of said bore; a plunger slidably positioned in said bore having a manually-engageable handle and latching means at an outer end thereof, a sealing member, and a mouthpiece element selectively engageable in sealed relation with said first end of said first tube, said element including a frangible sealing means selectively penetrated by said striker element upon activation of said manually-operable means.
