In order to reduce pain in needle insertion for hemodialysis, the author tried to develop a regional cooling patch employing an endothermic reaction of soluble chemicals. In this study, a prototype with urea was designed and evaluated by a human simulator to mimic temperature response by heat transfer from the blood flow. Surface area of the regional cooling patch was determined 1260 mm2 after the conventional handy-type regional cooling device. A prototype patch was made of a heat insulation sheet. Thirteen grams of urea was added to ten milliliters of distilled water inside the prototype patch. As a result of experiment, skin temperature of the human simulator kept between 15 and 20 degree Celsius for ten minutes.
