AK96血液透析机液路系统常见故障分析与维修

Common Fault Analysis and Maintenance of AK96 Hemodialysis Machine Fluid System

随着血液透析技术不断进步,血液透析已成为治疗慢性肾衰竭患者的有效方法之一,能帮助提高患者生存率,在治疗该病中发挥了重要作用。血液透析机作为提供有效透析治疗的医疗装备,其是否正常运行将直接影响透析效果,甚至威胁患者生命安全。因此,保证血液透析机的正常运行,熟练掌握血液透析机的基本结构、常见故障分析、维修方法,可以杜绝血透事故隐患,减少医患纠纷。血液透析机分电路控制部分、血路部分、液路部分系统,其中液路系统包括水控制单元、加热单元、透析液配制单元、除气单元、流量控制单元、超滤控制单元、漏血探测和排废液单元。本文以液路系统为例,分析设备常见的故障表现、故障原因、维修过程展开阐述,为临床工程师维修提供参考。

With the continuous progress of hemodialysis technology,hemodialysis has become one of the effective methods to treat patients with chronic renal failure,which can effectively help improve the survival rate of patients and play an important role in the treatment of the disease.As a medical equipment providing effective dialysis treatment,the normal operation of hemodialysis machine will directly affect the dialysis effect,and even threaten the life safety of patients.Therefore,ensuring the normal operation of the hemodialysis machine and mastering the basic structure,common fault analysis and maintenance methods of the hemodialysis machine can eliminate the hidden dangers of hemodialysis accidents and reduce the doctor-patient disputes.The hemodialysis machine is divided into circuit control part,blood circuit part and liquid circuit part.The liquid circuit system includes water control unit,heating unit,dialysate preparation unit,degassing unit,flow control unit,ultrafiltration control unit,blood leakage detection and waste liquid drainage unit.This paper takes the liquid circuit system as an example to analyze the common fault performance,fault causes and maintenance process of the equipment,and to provide reference for clinical engineers to maintain.
