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.
Claims6
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 resilient 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.
In a device for removing a lodged mass from the throat of a victim, the improvement comprising:
- a replaceable mouthpiece element, including a tube having a free end closed by a frangible membrane, and a vacuum-generating source having means for engaging said free end in sealed relation, said source including a resilient striker element for penetrating said membrane following positioning of said mouthpiece element.
A replaceable mouthpiece element for use with a device for removing a lodged mass from the throat of a victim, comprising:
- an elongated flexible tube having a free end selectively closed by a puncturable membrane, said end having means for selectively engaging a vacuum source means having means for penetrating said membrane.
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 resilient manually operable actuating element positioned within said tube selectively maintained in relatively cocked position;
- 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 including a recess at said second end;
- a plunger slidably positioned in said bore having a manually-engageable handle at an outer end thereof, including latching means cooperating with said recess;
- and a mouthpiece element selectively engageable in sealed relation with said first end of said first tube, said manually operable actuating element serving to open said sealing member between said mouthpiece element and said vacuum pump element in substantially instantaneous manner.
