Manual resuscitation device
First Claim
1. A device to assist with cardio pulmonary resuscitation comprising:
- a manually compressible and resiliently expandable bag constructed of an elastomer shell that encloses a breathable gas chamber having a volume capacity sufficient to inflate the lungs of a human patient when said bag is compressed, said shell having at least one compressible region constructed of a wall having less resilience than said shell'"'"'s average resilience.

Abstract
An improved cardiopulmonary resuscitation device for resuscitating human infants is provided. The device includes a manually compressible and resiliently expandable bag constructed of an elastomer shell that encloses a breathable gas chamber having a volume capacity sufficient to inflate the lungs of a human patient when the bag is fully compressed. The shell includes at least one compressible region constructed of a wall having less resilience than the shell'"'"'s average resilience. The less resilient region helps prevent over inflation of the patient'"'"'s lungs. The device further includes a patient interface assembly that is communicable with a breathable gas outlet of the bag breathable gas chamber, and a breathable gas source communicable with an inlet of the bag breathable gas chamber. The device can optionally include a breathable gas manometer to monitor backpressure from the patient'"'"'s lungs to further insure against over inflating the patient'"'"'s lungs.

-
a) a manually compressible and resiliently expandable bag constructed of an elastomer shell that encloses a breathable gas chamber having a volume capacity sufficient to inflate the lungs of a human infant patient when said bag is compressed, said shell having at least one compressible region constructed of a wall having less resilience than said shell'"'"'s average resilience, wherein said bag'"'"'s average shell thickness is substantially greater than the wall thickness of said at least one compressible region of lesser resilience; b) a breathable gas facial masked that is sized for human infants and is communicable with a breathable gas outlet of said bag breathable gas chamber; and c) at least one breathable gas source communicable with an inlet of said bag breathable gas chamber. - View Dependent Claims (25, 26, 27, 28)
