Abstract

A mouth-to-mouth resuscitator device for providing a physical barrier between a rescuer and a victim including a hollow tubular housing having an air input end and an air output end and counting a self closing one way valve having a disc shape secured between the housing ends and a pair of spaced apart rods secured to the disc for attaching the disc to a support plate, so that the inner end of the plate is received between the rods to support the valve disc and provide a hinge for dividing the disc into a pair of flaps to bend outward to an open position in response to forced air for transferring the air from the air input end to the air output end, and the flaps resiliently return to a closed position when the forced air has dissipated.

Claims

1. A device for a rescuer to resuscitate a victim, comprising:

a hollow housing having an input end for inserting forced air into the housing and an output end for discharging said forced air to resuscitate the victim;

a valve seat positioned in said housing between said ends, said valve seat including an opening;

a valve disc having an inner side and an outer side, said disc having an air closed position to close said opening of the seat and an air open position to permit flow of said forced air from the input end to the output end, said valve disc being positioned between the valve seat and the output end of the housing;

plate rigidly secured to the inside of the housing between the output end of the housing and the outer side of the valve disc, said plate have an outer edge and an inner edge, said outer edge of the plate being closer to the outer end of the housing than said inner edge; and

a pair of spaced apart rods secured to the outer side of the valve disc, said inner edge of the plate being received between the rods to attach tie disc to the plate for dividing the disc into a pair of movable portions, said portions moving from a closed position to an open position in response to said forced air.

2. The device of claim 1, wherein said rods tend laterally across said valve disc, the inner edge of the plate press fitting in the space between said rods.

3. The device of claim 1, wherein said disc is substantially oval shaped having a lateral width and a longitudinal length, said rods extending laterally across the disc at substantially the longitudinal center thereof.

4. A device for a rescuer to resuscitate a victim, comprising:

a hollow housing having an input end for inserting forced air into the housing and an output end for discharging said forced air to resuscitate the victim;

a valve seat positioned in said housing between said ends, said valve seat including an opening;

a valve disc having an inner side and an outer side, said disc having an air closed position to close said opening of the seat and an air open position to permit flow of said forced air from the input end to the output end, said valve disc being positioned between the valve seat and the output end of the housing;

a plate rigidly secured to the inside of the housing between the output end of the housing and the outer side of the valve disc, said plate having an outer edge and an inner edge, said outer edge of the plate being closer to the outer end of the housing than said inner edge;

attachment means positioned on the outer side of the valve disc, said attachment means securing the disc to the plate to divide the disc into a pair of movable motions, said movable portions moving from a closed position to an open position in response to said forced air;

a first post secured to the inside of the housing;

a second post secured to the inside of the housing in an opposed relationship with said first post; and

said plate having a first side edge and a second side edge opposed to the first side edge, said first side edge being attached to said first post and said second side edge being attached to the second post.

5. The device of claim 4, wherein said housing has substantially an oval shape, said plate extending laterally on the inside of the housing from said first side edge to said second side edge.

6. A device for a rescuer to resuscitate a victim, comprising:

a hollow housing having an input end for inserting forced air into the housing and an output end for discharging said forced air to resuscitate the victim;

a valve seat positioned in said housing between said ends, said valve seat including an opening;

a valve disc having an inner side and an outer side, said disc having an air closed position to close said opening of the seat and an air open position to permit flow of said forced air from the input end to the output end, said valve disc being positioned between the valve seat and the output end of the housing;

a plate rigidly secured to the inside of the housing between the output end of the housing and the outer side of the valve disc, said plate having an outer edge and an inner edge, said outer edge of the plate being closer to the outer end of the housing than said inner edge; and

attachment means positioned on the outer side of the valve disc, said attachment means securing the disc to the plate to divide the disc into a pair of movable portions, said movable portions moving from a closed position to an open position in response to said forced air,

said valve disc being sandwiched between the inner edge of said plate and said valve seat; and

said valve seat being press fitted inside said housing, said valve seat preventing inward movement of the valve disc toward the input end of the housing.
