Abstract
Abstract A THERAPEUTIC SHOWER HEAD IS DISCLOSED WHICH INCLUDES A COLLIMATOR FOR PRODUCING A SINGLE BEAM OF WATER. A SWIVEL ARRANGEMENT IS PROVIDED TO ALLOW THE DIRECTION OF THE BEAM TO BE ALTERED. A BEAM INTERRUPTER IS PROVIDED AT THE OUTPUT THAT PULSATES THE BEAM. THE INTERRUPTER CAN EITHER BE DORMANT OR IF SET INTO MOTION WILL DERIVE ENERGY FROM THE BEAM AND BEGIN A SUSTAINED OSCILLATION THAT WILL PERIODICALLY INTERRUPT THE BEAM. THE THERAPEUTIC BENEFITS OF THE SHOWER HEAD ARE DERIVED FROM BOTH THE SINGLE STEADY BEAM AND FROM THE PULSATING BEAM.
