Abstract: An apparatus and method for preventing contamination of the Post Anesthesia Care Unit of A Hospital by the use of a mask sealed to the patient's face and connected by a ventilator circuit to an airator that pulls a vacuum to exhaust the patient's expirations to the outside atmosphere. The disclosure also includes a "oxyvent" which is a tube adapted to be attached to an oxygen tank and to a patient to provide a higher oxygen ratio to the patient and to provide forced ventilation to a patient who has difficulty ventilating.

Abstract: A primarily radial load ball bearing includes an assembly of outer and inner race rings having confronting raceways for a plurality of balls and a unitary ball separator fabricated of a moldable resilient material, having an annular base and annularly spaced fingers defining an interrupted cylindrical rib which projects between the outer and inner race rings and provides pockets for confining each of the balls of the bearing. Each finger defines a pedestal supporting at least two ears which are integral extensions of the pedestal and which are radially separated from each other. One ear extends into one adjacent pocket, and the other ear extends into the opposite adjacent pocket. The distance between the confronting distal lips of the ears for one pocket is less than the diameter of the ball, so that the ears define a snap-in entry to the pocket. The ears, then, are designed to be resiliently yieldable relative to the supporting pedestals.
