First Claim
Patent Images
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.

Abstract
Many people do not have a physical feeling for what normal and abnormal blood pressure levels mean in relation to the forces exerted on the heart and blood vessels. A blood pressure simulation apparatus provides human subjects a means to physically feel simulated blood pressure levels through tactile feedback. Both normal and abnormal blood pressure cycles are simulated. Interfacing of the apparatus to an electronic blood pressure monitor is provided.

14. An apparatus for simulating human blood pressure cycles comprising:
-
an electronic control unit;
a pressurized fluid generator connected through a manifold to a pressure vessel whereby pressurized fluid from the pressurized fluid generator flows into the pressure vessel;
a electronic fluid pressure sensor in pressure communication with the pressure vessel and in electronic communication with the electronic control unit;
a first bleed valve adjustable by the user connected to the manifold to set a simulated, abnormal diastolic pressure level to be produced within the pressure vessel;
the electronic control unit cyclically operates a solenoid valve connected in series with the first bleed valve to control the simulation of abnormal human blood pressure cycles within the pressure vessel; and
the pressure vessel comprises at least one moveable boundary whereby a human can sense by touch, the relative magnitudes of the oscillating pressures within the pressure vessel. - View Dependent Claims (15, 16, 17, 18, 19)

20. An apparatus for simulating human blood pressure and providing tactile feedback comprising:
-
a pressurized fluid generator connected by a flow conduit to a pressure vessel whereby pressurized fluid from the pressurized fluid generator flows into the pressure vessel;
the diameter of the flow conduit is smaller than the pressure vessel diameter thereby creating force amplification within the pressure vessel compared to the conduit;
an element to control fluid pressure level within the pressure vessel;
at least one pressure level within the pressure vessel is equivalent to an abnormally high, human systolic blood pressure; and
the pressure vessel comprises at least one moveable boundary whereby a human can sense by touch the magnitude of the pressure level within the pressure vessel. - View Dependent Claims (21, 22)
