血透机在临床使用过程中 ,医护人员、工程师对血透过程中透析液的电解质 ,如 :Ｎａ +、Ｋ +、Ｃａ2 + 、Ｍｇ2 + 、Ｃ1-、ＨＣＯ3 -等参数值很关心 ,但是往往忽略了透析液中ＰＨ值对血透机及血透效果的影响。其实当透析液的ＰＨ值出现波动。特别是偏离标准值较大时 ,对血透机影 In the course of clinical use of hemodialysis machines, medical staff and engineers are very concerned about the electrolyte values ​​of dialysate during hemodialysis, such as: Na+, K+, Ca2+, Mg2+, C1-, HCO3-, etc., but often The influence of the pH in the dialysate on the hemodialysis machine and the hemodialysis effect is neglected. In fact, the pH of the dialysate fluctuates. Especially when there is a large deviation from the standard value,
