  • Patent number: 5205293
    Abstract: The present invention provides a method of measuring skin blood flow on a test site using a blood flow meter. The method includes the steps of calibrating the probe of the blood flow meter, using a bio-simulating model to produce a thermo-EMF flow curve, attaching the probe to a site to be tested to generate an electromagnetic force for the test site, and determining the skin blood flow at the test site by comparing the electromagnetic force to the thermo-EMF curve. The method may also include the step of maintaining the temperature in the probe at a value slightly higher than that of the test site.
