82th day of attachment

In the process of fixing my terumo infusion pump, STC – 503….
Since I suspect that the previous person replaced a wrong type of battery for it, I changed the battery with another pump’s battery to make sure the problem caused by the battery instead of the PCB board. If that’s the case, I will purchase the batteries, as there is none in the inventory. May be checking with the quotation file to see any purchase was done a few weeks ago. Based on the quotation that we had, it seem no one did any purchase for the batteries lately. After doing the flow test and occlusion test without AC power, it seems the problem involving the battery.

Around late morning, the Profile system is able to work and every one of us are glad as we can update and start the repairs that were sent to use for the past 3 days. I finally able to update what I have done for repairing the sphygonomomamomter and the alternating mattress pump system. We received calls from the training centre which is under human resource department. The faults for the 3 manikin were unable to switch on, cable wore out and unable to power up respectively. We managed to solve the 2 manikins which are resusci anne and one of the casing contained 2 extra cables for the controllers. We replaced the cable and they worked.

In the afternoon, pump control for betabed from huntleigh do not have air pressure due to one of the 3 tubing came off. After reconnection of it, the air pressure seems quite low so I replaced the air drive assembly.

Ventilator 840 series having a fault which displayed “Safety valve open” error message as usual basis, we did the SST test first. After the SST is done, the error message no longer displayed. It occurs to me that the problems usually seem due to the end-user.

The MEDI-MIZER also known as the Profile is down since Tuesday. I did some repair in the morning. Trying to figure out the problem with the infusion pump as it is unable to charge. After I dismantled the device, I found out that the battery used is not meant for the infusion pump. I thought of replacing the battery only if it was replaced at least 2 years ago. I just hope that the Profile software is able to be used soon as it is quite difficult to check whether someone has replaced anything for a particular device.

When the system is up, I will take an infusion pump that is due this month for maintenance. Most of the pumps due are under warranty so I only have a pump under my hand. I want to have a try in repairing intermittent suction unit from Allied, Vacutron since I always deal with Datex-Ohmeda’s ISU. I found out that the vendor not willing to give us the quotation of the parts that we wanted.

The wall mounted thoracic suction unit was supposed to send down due for preventive maintenance. However, the nurse complaint that something is missing which we are not sure what exactly it is. There is no service manual in the cabinet and could not locate the soft copy of the service manual. There are still a lot of repair to be done.

80th day of attachment

The day was separate half preventive maintenance and half corrective maintenance.

My colleague and I went to SOC C (optometry clinic) to do preventive maintenance for indirect opthalmoscopes, aspirator and projector. We managed to finish the maintenance for this department. However, the power supply of a slit lamp unable to power up after switching on. We found out that there are two fuses blown which are hidden behind the main power slot after calling the vendor. The problem was someone used lower current rating fuses instead of the stated 4A fuse. The fuses are badly burnt. A commissioning of sleep study system took place at the material management department store. More of the software commissioning and it is the first time that I attend such commissioning. The system consists of Sp02 and EEG. It is a diagnosis device.

I am sick as suffering from a very bad headache.

78th Day oF attAchMent

In the morning.....
My colleague and i delivered all the devices that are repair and ready for sending back to the various wards. We kind of spend 1 hour delivering all the devices. Shortly after i returned back to the BME, Staff Nurse called to notify us about the PCA Pump that was due last month. We did not get a chance to do last month as it was being occupied by the patients most of the time. I went up to Operation theatre as soon as my colleague told me about the pump is ready to be collected. I did the bolus, flow, occlusion and leakage current test. I took lesser time compared to the first time i did the maintenance for it.

In the afternoon.......
I received a call from SICU that the ventilator 840 series having an error message which said "power loss & recovery due to pre-existing DEVICE ALERT. Check alarm log. EST required." I recalled that i meet with this problem a few days before. The same device having the same problem again. I did the SST and EST again to see where the fault is this time. EST required a "golden tubing" which is just a short tube connecting From-patient port to the To-patient port for a few small tests such as the compliance test. After the tests were done, i asked the staff nurse to check and sign for what i have done with the ventilator. I was given a task by my colleague which is collecting the loaner endoscope and informed the vendor about endoscopes ready for returning and sending for repair. When i was in the endoscopy department, nursing officer said that the loaner endoscope is not ready for returning as gastroscope is spoilt again and requested vendor to send a service engineer down to service the endoscope. I went back to BME to notify my colleague about it and did some repair on the devices that was sent down by porter attendent early today.
