肾衰竭治疗的智能腹膜透析系统

Intelligent Peritoneal Dialysis System for the Treatment of Renal Failure

腹膜透析是治疗急性肾衰、慢性肾衰和尿毒症等肾衰竭疾病的重要手段.本文采用自行研制的多功能蠕动泵和PLC-单片机-触摸液晶屏一体化的电气结构,实现整个透析治疗过程的全自动协调控制.该系统通过中文界面引导用户方便使用和设置适合患者医疗要求的透析参数,并且通过电气测控系统实现输液、抽液流量、流速和温度等透析参数的控制和声光自动警示;同时,该仪器融合了独特的用户治疗信息自动存取的智能卡系统,便于医生查询和诊治以及实现远程诊治。该系统为提高肾衰竭腹膜透析治疗的技术水平和临床应用研究奠定了基础。

Peritoneal dialysis is an important approach to the treatment of renal failure diseases such as acute renal failure, chronic renal failure and uremia. In this paper are presented the application of the multifunction squirm pump developed by authors, the use of PLC and single-chip to control harmonically, and the instituition of full automatic dialysis therapy. Man-machine interface with integrative touch lictuid crystal display is adopted in the system, and Chinese interface is used to display and operate so that user can manipulate it in a guiding way. Hence, the whole process is simple and clear. At the same time, it is very easy to set dialysis parameters suited for medical treatment demands of all kinds of patients. Through squirm pump, electric valve, electronic weighing system and electrical heating system, the accurate control of input and output dialysis volumes, flow velocities, temperature, and other parameters are achieved and automatic alarm function is also implemented. Meanwhile, particular intelligent card system that can access automatically the user＇s treatment information is syncretized, which is convenient for doctor to make a diagnosis and give treatment or to carry out remote treatment. This system plays an important role in the improvement of peritoneal dialysis technique for renal failure treatment and clinical implementation.
