SYSTEMS AND METHODS FOR LOCATING A BLOOD VESSEL

摘要

Systems and methods for locating a blood vessel are described. One described method includes receiving a first temperature measure associated with a first point on a surface of a skin; receiving a second temperature measure associated with a second point on the surface of the skin, and determining a differential between the first temperature measure and the second temperature measure. The method further includes generating an output signal indicating the presence of a blood vessel if the differential exceeds a threshold.
