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.
Claims76
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.
A device for the removal of a lodged mass from the throat of a victim, comprising:
- a housing having a principal axis, said housing having a laterally-extending member having means for selectively engaging a free end of a mouthpiece element;
- said laterally-extending member including a laterally-extending channel;
- said housing having an axially-extending bore communicating with said laterally-extending channel, and manually operable valving means disposed within said bore;
- an axially-extending barrel, an elongated vacuum plunger slidably positioned within said barrel, and having locking means thereon, said barrel having corresponding locking means thereon for selectively maintaining said plunger in outward, vacuum-generating position;
- movement of said plunger to an inward position serving to contact said valving means and return it to closed condition.
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;
- said vacuum source including a manually-operated single stroke vacuum pump plunger, said vacuum pump including latch means for maintaining said plunger in vacuum-creating position.
An antichoking device for removing an object in the throat of a victim, comprising a tube said tube having a length and a first end and a second end, one end of said tube having a mouth piece removably secured thereto, the second end of said tube having a striker, said striker having a cocked and uncocked position and having a trigger for moving said striker from a cocked to an uncocked position, said tube having a pump in communication with said tube, said pump having a first end communicating with said tube and having a plunger slidably movable in said pump from a first position to a second position, said plunger creating a vacuum in said pump when said plunger is moved to said second position said plunger being releasably retained in said second position, said tube having a frangible seal selectively penetrated by said striker upon activation of said striker.
A device for vacuum removal of a lodged mass from the throat of a victim comprising a first tube having first and second ends, said first end having a mouth piece removably secured thereto in a substantially leak proof relation, a striker having a cocked and uncocked position and a trigger for moving said striker from said cocked to said uncocked position, a vacuum pump communicating with said tube, said pump including a plunger slidably positioned in said pump said plunger being manually movable from a first position to a second position in said pump and being releasably retained in said second position until said striker penetrates a frangible seal.
In a device for removing a lodged mass from the throat of a victim, the improvement comprising a replaceable mouthpiece, including a tube having a free end closed by a frangible membrane and a vacuum generating source, said vacuum generating source including a striker for penetrating said membrane following positioning of said mouthpiece, said vacuum generating source including a plunger said plunger manually movable from a first position to a second position to generate a vacuum, said plunger being retained in said second position until said frangible membrane is pierced by said striker.
A device for use in removing a lodged mass from the throat of a victim, said device comprising:
- (a) a mouthpiece, said mouthpiece having a generally tubular sleeve having a first end and a second end, said first end being open and said second end being sealed by a frangible membrane;
- (b) a striker, said striker having a first and a second end, said striker further comprising a sealing means and a cocking member;
- (c) a housing, said housing comprising a first bore creating a first end opening and a second end opening, said first end opening having a means for receiving said second end of said mouthpiece;
- said striker being slidably received within said bore;
- (d) a release member, said release member adapted to releasably restrain movement of said striker when said striker is moved into a cocked position;
- (e) a plunger, said plunger further comprising an engageable handle, and a sealing means;
- and
- (f) a second bore within said housing;
- said second bore extending transverse from said first bore to create a third end opening in said housing;
- said second bore being interconnected to said first bore between said first and second end openings;
- said plunger being slidably disposed within said second cylindrical bore.
A mouthpiece element for use in a device for removing lodged particles from the throat of a victim, said mouthpiece comprising a first end and a second end with an air passageway from said first end to said second end, said first end being adapted to inserted into the mouth of the victim, said second end of said mouthpiece comprised of engagement sleeve with an open end, said open end being covered by a piercable membrane, said membrane being replacably secured to said engagement sleeve, said membrane being held in place on said sleeve by a collar.
A device, for use in removing a lodged mass from the throat of a victim, said device comprising:
- a housing, said housing comprising:
- a first bore creating a first end opening and a second end opening, and a second bore being interconnected to said first bore between said first and second end openings and creating a third end opening in said housing;
- a striker, said striker having a first end and a second end, said striker being slidably received within said first housing bore in sealed relation;
- a trigger, said trigger being adapted for releasably restraining movement of said striker when said striker is moved into a cocked position being distal from said first end opening;
- a mouthpiece, said mouthpiece having a first end and a second end, said first end being open and said second end being sealed by a frangible membrane;
- said second end of said mouthpiece being received at said first end opening of said housing with said frangible membrane sealing said second end opening and being selectively penetrated by said striker;
- and
- a plunger, said plunger being slidably within said second bore in sealed relation.
