1. An apparatus for simulating human blood pressure cycles and providing tactile feedback comprising:

  • an electronic control unit;

    a pressurized fluid generator connected to a pressure vessel whereby pressurized fluid from the pressurized fluid generator flows into the pressure vessel;

    an electronic fluid pressure control element electrically connected to the electronic control unit;

    an electronic fluid pressure sensor in contact with the pressurized fluid and in electronic communication with the electronic control unit;

    the electronic control unit controls the simulation of human blood pressure cycles within the pressure vessel;

    the human blood pressure cycles comprise oscillating pressures between simulated abnormal systolic and diastolic blood pressure levels with an oscillation period equal to a human cardiac cycle; and

    the pressure vessel comprises at least one moveable boundary whereby a human can sense by direct touching of the pressure vessel, the relative magnitudes of the oscillating pressures within the pressure vessel.
