Study on Temperature Control System for Heat Probe Used in Cruor after Gynecologic Surgery

The temperature of heat probe must be well controlled for an efficient cruor of surgery wound and the safety of patients.This paper proposes a system including a thin film resistance temperature detector(RTD)and a bridge circuit for controlling the temperature of heat probe during the cruor after gynecologic surgery.The temperature control was achieved by a PID of which parameters were set sectionally.It is demonstrated that the proposed system can precisely and efficiently control the temperature,and circumvent the environmental effect.
