A Biology Experimental Study on the Effect of Bionic Painless Needles on Pain Relief

摘要

Several kinds of painless biomimetic needle structures with high drag reduction effect were obtained by means of experimental optimization design. The changes of heart rate and blood pressure as the index of pain sensitivity were selected. The experimental study on the biological function of bionic needles was carried out. Rat heart rate, blood pressure and other indicators of changes in the law of pain is found out. The pain reduction effects of several bionic painless needles are tested by the experiment. The results of the experiment had been consistent with experiment optimization design.
