The aim of this study is to analyze the palpation and perforation motion performed by the practitioner during the insertion of a catheter while measuring the loads applied on the skin and the veins. These experimental measures will be used for the design of a more realistic peripheral venous catheter insertion simulator in order to better prepare healthcare students for their first in vivo venous puncture.
