摘要
Here is disclosed a method for measurement of viscosity change in blood or the like comprising steps of disposing a sensor including of an endothermic or exothermic element in blood or the like, stimulating blood or the like so as to cause a viscosity change therein and detecting the viscosity change by continuously measuring any one of changes occurring respectively in a average temperature ϑ w or a surface temperature ϑ s of the sensor containing therein the endothermic or exothermic element, a differential temperature ϑ w - ϑ ∞ or ϑ s - ϑ ∞ between a temperature ϑ ∞ of blood or the like and ϑ w or ϑ s, a kinematic viscosity ν of blood or the like and a heat transfer coefficient on the sensor surface. Such measurement may be performed by a sensor comprising an electric insulator through which lead wire extends, metallic wire wound around the electric insulator and connected at opposite ends to the portions of the lead wire exposed on the surface of the electric insulator, and a portion of the electric insulator, around which the metallic wire is wound, being coated with suitable material.
