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.
Claims8
Apparatus for dislodging a mass from an animal airway comprising:
- (a) means for sealing the nasal and oral cavities including means for depressing the tongue of the animal and establishing an unobstructed path from the oral cavity above the lodged mass and terminating in a conduit emerging from the oral cavity,
- (b) a sealed evacuated canister having means for unsealing the canister, and
- (c) valved conduit means suitable for communicating in a sealed relation the interior of the evacuated canister and the conduit emerging from the oral cavity.
Apparatus for outwardly moving a mass from a lodged position in an animal airway comprising:
- (a) means for sealing the nasal and oral cavities of the animal, said means including means for depressing the tongue of the animal to thereby establish an unobstructed path above the lodged mass through the oral cavity;
- (b) a conduit communicating at one terminus with the oral cavity and at the other terminus exteriorly of the oral cavity, said conduit extending through the means for sealing the oral cavity;
- (c) a sealed canister having a substantially reduced internal pressure and having associated means for forming an opening in the sealed canister;
- and
- (d) valved-conduit means disposed in a sealed relation with an opening in the canister and the conduit exterior to the oral cavity.
