ABSTRACT:
In a model for practicing artifical respiration by means of a mouth-to-mouth or mouth-to-nose resuscitation procedure, at least a part of the respiratory tract of the model is simulated by a plurality of successively disposed balloons which are each separably connected by their inflation connection to the closed end of the respective preceding balloon in interconnected relationship to form a continuous flat strip. The strip is wound to form a coil, with the coil being mounted rotatably in the model. In that way a plurality of such balloons are disposed in a coil and replacement of a used balloon by a fresh balloon is affected by pulling the used balloon out of the mouth or nose opening of the model and separating it from the adjoining balloon in the strip of balloons.
