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.
