Design of constant temperature heating circuit for medical hyperthermic perfusion system

Medical hyperthermic perfusion is the fifth effective anti-cancer treatment method which has been widely used in recent years. The core of the system is the constant temperature heating system of water tank. In this article, a constant temperature heating circuit is introduced. By adjusting the conduction angle of SCR and combining with PID algorithm, the omnidirectional adjustable power constant temperature heating system is realized, and the auxiliary protection circuit meets the requirements of medical application.
