Abstract: A disposable self-inflatable rescue mask for ventilation CPR (cardio-pulmonary resuscitation) comprising a transparent, flexible form-retaining plastic dome-shaped foldable portion having around its peripheral edge an inflatable bladder provided wtih a built-in self-sealing air valve, which allows the ambient air to flow into the inflatable bladder and self-seals the air in the self-inflated mask which retains its shape firmly, said bladder being shaped to fit around the nose and mouth areas, and effectively seal against the patient's face; and a blow-in tube disposed in an opening at the apex of the dome is provided with a mouthpiece for delivery of expired air to the patient.The mask is packaged in a carrying case comprising two similar parts to form a container which is shaped to receive said deflated mask in a flattened and folded state, and sealed with a closure means.

Abstract: A nonvented gravity fed exponential mixing and delivery system and apparatus for the administration of a drug in a precalculated manner to give constant therapeutic blood plasma levels in the recipient, (patient), which provides an inexpensive, quick and simple exponential mixing procedure to deliver an infusion containing exponentially decreasing concentrations of a drug, which the exponential mixing of a dilute solution of the drug or isotonic solution which flows by gravity from a conventional IV container, through a coupling means, into a vertically aligned nonvented nondeformable mixing chamber, filled to capacity with a concentrated solution of said drug, said mixing container being provided with a verticle inlet conduit means and a vertical outlet conduit means at opposing ends, each conduit means extending into said mixing container at a height to provide a sufficient height differential to induce exponential mixing of the solutions, to effect an exponentially decreasing concentration of said drug dur
