Computer simulation of needle venepuncture for the development of automatic blood sampling systems

To achieve automatic needle puncturing for automatic blood sampling, we studied peak waveforms of the puncture forces developed during penetration of a blood vessel. Computer simulations of controlled needle puncture were performed using data from experiments on puncturing a rabbit's ear vein. Reproducible results of successive puncturing suggested that this simulation could be applied to the control of needles used for automatic blood sampling.
