Method and apparatus for monitoring vascular flow |
摘要 |
A method and device for measuring blood flow through a blood vessel within human or animal bodies. It utilizes the principle of energy conversion to heat by myocardial activity, organ metabolism, and laminar frictional flow in blood vessels and measures the heat dissipation through the vessel wall with obstruction to flow. When the device of the invention is placed next to the vessel wall, the output signal correlates blood flow with temperature. With an obstruction to flow, the temperature drops. The device is placed in series proximal and distal to the repaired vessel to be studied. The leads are brought through the skin and attached to a temperature monitor.
