64th day of attachment
Continue our journey of Preventive maintenance by starting off to X-Ray departments. We had done the aspirator and video printer from there. There seem more devices due for this month compared to the list. After checking with colleague, most of the unlisted. About seven devices remain unallocated. There is an infusion pump that was hidden in the linen room at ward 10. Thankfully, we found it and preventive maintenance is then done for it. When it was taken back, I found out the tubing clamp is faulty which unable to clamp the tubing. While analyzing the fault, the rod is croak. Therefore, the solution to the fault is replacing the rod and cleans the area where the rod is inserted with alcohol pad.
During the later part of the day, we went to SOC L, Endoscopy and occupational therapy rehabilitation. We only able to do the maintenance for Endoscopy at 3pm as the last case will usually end at 3pm.We spent almost the whole day doing preventive maintenance. It is quite a time consuming routine to perform every month. For the last hour, I did some repair like solving the leakage of double flowmeter by tapping the area of oxygen probe that is connected to the twin flowmeter. There’s the usual problem that arise for flowmeter. The preventive maintenance for transport physiologic monitor, propaq series is changed from 6 monthly to yearly to prevent any confusion among biomedical engineering staffs.
Since my other colleague is doing an infusion pump, STC-503 and she suspected that the HIC board is spoilt so exchanged the HIC board to make sure that’s the fault. When I turned on the pump, I saw smokes fuming out from the HIC board area. I was surprised and afraid that the wrong connection may cause it. My supervisor told me that there is nothing wrong with the connection of the connectors to the board. One of the resistors in the board is burnt. However, we are not sure which resistor is burnt and the manufacturer no longer producing STC-503 PCB boards as production of STC-508 and STC-503 terminated.
