Application of Hybrid Petri Nets for a Drawing Blood Flow from Fingertip.

Our objective of this study are to make a fluid dynamical model and to conduct the flow simulation for obtaining a large amount of drawing blood from a fingertip. The processes of drawing blood are hybrid systems including both the continuity system of blood flow and the discrete systems of cuff pressing and puncture. Therefore, we made the modelling of the fingertip drwaing blood process from the analogy of fluid daynamic tank and pipe systems control using hybrid Petri nets. Using the hybrid Petri nets simulation with cuff pressing and puncture modeled as discrete and blood flow modeled as continuity, we confirmed that the simulation results were agreement with the experimental drawing blood data.
