RESUMO
AIM For the evaluation of algorithms for circulator drug delivery, a new simulator was developed. METHODS The Clement Yu's non-linear canine circulatory system model was modified for the use of the part of digital dog of the simulator. And the other parts of the simulator were built by the means of object-oriented designing (OOD) with Visual C++ language. The proportion of mean arterial blood pressure in the range of?0.667 kPa of the object value was contracted to T_ MAP , and the average value of integral of excess of the range above was contract to S_ MAP . The difference of T_ MAP and S_ MAP of SPN MMAC(Multiple Model Adaptive Control) controlled hypotension and SPN constant-rate-controlled hypotension had been studied in vivo. This process was repeated in simulation system. The difference of simulator and animal experiments was studied while they were evaluating the SNP MMAC algorithms for controlled hypotension. RESULTS The mean arterial blood pressure graphs of the simulator and animal experiments acted similarly when they evaluated the SNP MMAC algorithms. The graph of mean arterial blood pressure of simulation was similar to that of the animal experiment when the MMAC was evaluated. CONCLUSION The new simulator can evaluate algorithms for circulator drug delivery and it's helpful to the building of such systems.-
