Intelligent peritoneal dialysis system for the treatment of renal failure / 生物医学工程学杂志

ABSTRACT

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 liquid 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.
