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

  • an elastomeric hollow bulb;

    a pressurized fluid generator connected by a flow conduit to the bulb whereby pressurized fluid from the pressurized fluid generator flows into the bulb;

    the diameter of the flow conduit is smaller than the bulb diameter thereby creating force amplification within the bulb compared to the conduit;

    an element to control fluid pressure level within the bulb;

    at least one pressure level within the bulb is equivalent to an abnormally high, human systolic blood pressure; and

    the bulb comprises at least one moveable boundary whereby a human can sense by touch the magnitude of the pressure level within the bulb.
