Venipuncture method |
| abstract |
A method of effecting venipuncture in the human body includes the steps of cooling the skin over a venous area of the body by applying a cold pack thereto and providing on the cooled skin in heat exchange relation thereto a layer of an enantiotropic cholesteric liquid crystalline phase material exhibiting a mesophase color change at a temperature reached by the skin due to venous blood flow, warming the cooled skin by venous blood flow in such area thereby to produce a mesophase color change in the material delineating a vein therebeneath, and directing an instrument for venipuncture to a site in such area indicated by the delineation to constitute the location of a vein. |
