Independent Claim
206 words
In a manual resuscitator comprising a bag having an inlet valve and an outlet opening; a valve housing having a bag end and a patient end, an opening in each end, and defining an interior passageway from said bag-end opening through said patient-end opening, said valve housing being connected at said bag end to said outlet opening; a non-rebreathing valve mechanism disposed inside said valve housing between said bag-end opening and said patient-end opening; the improvement comprising a lavage port having an inside diameter of less than about 1/4-inch disposed in said valve housing between said non-rebreathing valve mechanism and said patient end opening, wherein said lavage port does not lie on a longitudinal axis extending through said valve housing and out of said patient end opening such that a solution introduced through said lavage port does not pass through said lavage port in a linear route directly along the longitudinal axis extending through said valve housing and out from said patient end opening, and accordingly such that any matter ejected from a patient connected to said patient end opening cannot travel along the longitudinal axis through said patient end opening in a linear route and exit said lavage port without deviating from that longitudinal axis.
