碩士 === 中原大學 === 醫學工程學系 === 82 === In this paper, a preliminary monitoring and controlling system has been developed consisting of a personal computer with a dia- lysis machine. The serial interfaces including a singal process- ing card , Multi-8255 and an AD/DA interface card, were used for communication. By using the developed software in C language , graphics are created for monitoring the dialysis machine so that patient and system conditions may be easily understood. The moni- toring conditions include dialysate temperature,venous pressure, dialysate pressure , conductivity of dialysate ,total amount of ultrafilteration ,target of ultrafilteration , ultrafilteration rate, blood flow rate,blood leak and air bubble.The control sys- tem include the comfortable dialysis programing control of blood flow rate,the alteration of setting the mode of dialysis machine and the threshold of monitoring items. In this investigation, we execute preliminary for the central monitoring ／controlling sys- tem and try to expand connecting with two dialysis machines. The singal processing card has been accomplished and produced.In hos- pital,the system is reliable and safe during the dialysis The system is now available that allow for monitoring and cont- roling one dialysis machine. In the future , it can connect with multi-dialysis machines to construct a network system . It will reduce the burden of physician and increase the safety of patient during dialysis treatment.84
