Abstract：Objective To discuss the cleaning and maintenance methods of AB suction pipe of GAMBRO AK series hemodialysis
machine. Methods The heated dialysate was used to treat the AB suction pipe, and the ion content in the crystallization and residual
liquid of AB suction pipe with different water temperature, soaking time and frequency was compared to determine the optimum
treatment conditions. Results More crystals and residues on the dialysate AB tube were eluted with the increase of water temperature
and the prolongation of time, and there was a significant difference (P<0.05). There was no significant difference when the water
temperature exceeded 80 ℃ and the time exceeded 60 s (P>0.05). There was no significant difference in the crystals appearing in
AB pipette, as well as the sodium, potassium, and calcium ions in the residual liquid when the treatment was carried out after the
first, second and third shifts of dialysis (P>0.05). Conclusion The optimal treatment condition is to soak the AB suction pipe in
80℃ dialysis water for 60 s after daily dialysis. The method has the advantages of simple operation and low cost with good treatment
effect. It can reduce the failure rate of dialysis machine.
