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.

A method of measuring skin blood flow on a test site using a blood flow meter having
- a probe having a heated disc, a heat-sensitive ring plate, and plural thermocouples arranged in series between said disc and said ring plate
- the method comprising the steps of
- calibrating the probe by means of a bio-simulating model, having similar thermal properties to a test site to produce a thermo-EMF flow curve,
- attaching the probe to a test site for generating an electromagnetic force in response to the test site, and
- comparing the electromagnetic force of the test site with the thermo-EMF curve produced in the calibrating step to determine the skin blood flow of the test site.
