Development of fuzzy temperature control system for perfusion hyperthermia of the bladder tumor

摘要

Perfusion hyperthermia is the first choice to treat tumor in the bladder, accordingly, accurate measurement and control of the perfusion water temperature is the key technology to decide the curative effect of hyperthermia for the tumor in bladder. Recently, for different kinds of machines of hyperthermia at home and abroad, it is difficult to realize online monitor and high-precision control of the hyperthermia temperature of the tumor tissue in bladder. Aimed at this, in this paper a method is proposed to realize nondestructive measurement of the temperature of tumor tissue via a micro temperature sensor buried in the head of a triple-cavity tube, fuzzy control algorithm is applied, and a control device is designed to perform the online monitor and intelligent control on the hyperthermia temperature of the tumor tissue in bladder. The experiment result shows that the method of real-time monitor and control on the hyperthermia temperature of the tumor tissue in bladder is feasible, and the developed monitor system is running reliably, easy to operate and gets a good control effect.
