| 摘 要： | 血液变温在临床上得到广泛应用,如体外循环癌症全身灌注热疗、人体复温及器官移植手术中的血液变温等。目前医疗界应用的血液变温系统一般都是专门化的设备,存在体积庞大,扩充升级困难等缺点。我们介绍了新型基于计算机集散控制思想设计的易于硬件及软件扩展、微型化,集成了治疗管理功能的血液变温系统。并以全身灌注热疗应用为例进行了系统模拟实验。

| Abstract: | Blood temperature-varying has been widely applied in clinical practice such as extracorporeal circulation for whole-body perfusion hyperthermia(WBPH),body rewarming and blood temperature-varying in organ transplantation.This paper reports a novel DCS(Computer distributed control)-based blood temperature-varying system which includes therapy management function and whose hardware and software can be extended easily.Simulation results illustrate that this system provides precise temperature control with good performance in various operation conditions. |
