Exploration of faults in medical compressed air pump stations
LI Chao
Abstract：Ventilator plays an important role in the rescue and treatment of patients,and its operation requires compressed air.In 2016,two new compressed air pump stations were added to the ICU to provide compressed air for ventilators.The engineer found abnormal water content in the compressed air intake filter of the ventilator during an inspection.Through a series of investigations and experiments,variables were gradually eliminated.By analyzing the internal structure,main component functions,and principles of the pump station one by one,it was inferred that the faulty component was the refrigerated dryer.Coincidentally,a pump station malfunctioned and an independent refrigerated dryer was added to the outlet of another pump station during replacement.After running,it was verified and inferred through testing.Finally,the cause of water ingress in the pipeline was identified through destructive disassembly of the scrapped pump station residue.
