Abstract
With developments in medical electronics and other advanced electronic techniques a new trend in prosthetic techniques for internal organs is arising. It comes not noly from medical electronics but also from the techniques of industrial electronics. Moreover, progress in precision mechanical engineering is rapidly extending the life of apparatus which has to operate continuously for many years, and it is now possible to make artificial internal organs. An area, discussed here, in which the progress of technology has brought achievements is that of artificial heart systems employing the circulatory model with autonomic nerve. The model is controlled only the changes of CO2 density and mean blood presser. Heart rate, minute volume, mean blood pressure of the artificial heart system employing the circulatory model is evaluated with a mock circulatory system.
