Development of a high precision hyperthermic perfusion intraperitoneal treatment system

Objective To introduce the design principle and overall composition of high precision hyperthermic perfusion intraperitoneal treatment system.Methods "BR- TRG-Ⅱ type high precision hyperthermic perfusion intraperitoneal treatment system was composed of four parts including the control system, the external circulatory system, heat exchange system and the internal circulatory system.Functionally, five subsystems were incorporated including computer control, data detection, heating and cooling,circulation and alarming.Results The system has dedicated hyperthermiac computer software, full dynamic control in the total course of treatment , and can realize many functions including the treatment parameter settings, adaptive temperature control, treatment data show, automatic storage and alarm.Animal experiments and preliminary clinical results showed that the temperature measurement accuracy was up to±0.1℃, the temperature control accuracy up to ±0.16℃, and the peritoneal fluid infusion speed precision up to 5%.All performance fully met the design requirements for clinical use.Conclusion BR-TRG- Ⅱ -type hyperthermic perfusion intraperitoneal treatment system meets the design requirements in temperature control, heating and cooling, which is stable, safe, reliable and easy to use, therefore warrants wider use for clinical purposes.
