麻醉靶控输注工作站系统的研制

Development of A New Target Controlled Infusion System for Anesthesia

为弥补现有的独立输液泵式TCI系统在输注功能与监控方面的不足,设计开发了新型靶控输注工作站系统,它由上层的工作站与下层的多个输液泵构成.工作站采用嵌入式系统,硬件配高性能CPU与大尺寸的触摸液晶屏.依靠工作站端软件,系统支持十余种药物的基于药代动力学模型的靶控输注、带有输注曲线画面的实时监控、预测监控、病例查询及丰富的人工操作等功能.软件采用先开发后移植的开发过程,以面向对象的分析设计方法,采用多线程程序设计,提高了系统运行的效率和可靠性.

A new computer controlled infusion system for anesthesia drugs is developed, which consists of a workstation and one to three infusion pumps. An embedded system with a high performance micro-processor and a large-sized touch screen are used in the workstation. By the software running on the workstation, this infusion system supports some new functions： controlling 11 drugs＇ infusion by 17 pharmacokinetic models, monitoring with real-time chart view, predictive monitoring, querying case history, and so on; these functions are difficult to implement on the stand-alone pump. The soft-ware is developed by object oriented programming （OOP）, multi-thread technologies. Simulation and clinic infusion demonstrate the correction and advantage of this system.
