一台上海产TX—25型人工肾新机器,经临床4次透析,每次机器运行5～6小时,机器工作正常。最近临床透析时发现:机器运行时间超过大约1小时后,透析液温度不稳定;有时还会超温报警,引起透析液停止加热,加剧了透析液温度不稳定。透析一次需反复调节温度控制旋钮。从电路原理角度分析:透析液温度不稳定与温度指示、温度控制、超温报警等电路皆有关联。首先检查温度指示电路。用同型号
A Shanghai-born TX-25 artificial kidney new machine, the clinical dialysis 4 times, each machine running 5 to 6 hours, the machine is working properly. Recent clinical dialysis found that: the machine running time more than about 1 hour later, the dialysate temperature instability; sometimes over-temperature alarm, causing the dialysis fluid to stop heating, exacerbated the dialysis fluid temperature instability. Dialysis need to repeatedly adjust the temperature control knob. From the circuit principle point of view: dialysate temperature instability and temperature indication, temperature control, over-temperature alarm circuit are all related. First check the temperature indicating circuit. With the same model
