106th day of attachment

Today is my last day of work and i really enjoyed myself during my experience in Alexandra Hospital. I finished my report and let my supervisor to look through it. I really like to thanks every Biomedical engineering staffs to make my experience so wonderful. I really learnt quite a lot of things from them.

105th day of attachment

I continue doing my report and help up the administrative staff to do paper work.

104th day of attachment

In the morning, i continue doing checking for the other 2 devices that are requested as loan. Initially, I just connect the resuscitator with the oxygen cylinder and the patient valve to check for its working condition. Later, the flow analyzer was used to check the accuracy of the tidal volume that it produced and breath per minute. My colleague and I just simply check the defibrillator by having physical check. We making sure of the paddles' working condition. For Lifepak 12, it is more sophisticated compared to Lifepak 20 as it has more functions. At 3am, it will do a self – test automatically so pacer not recommended to be connected to the device unless it required to be used. After the staff who is in charge of this event came to collect the devices, i continue doing my report and a bit of my presentation.

In the afternoon, alternating mattress pressure system, AlphaxCell is sent down for repair. The fault lies with the parts of the connector stuck inside of the connector of the mattress. We solved the problem by removing the part of the connector instead of replacing with a new one. An suction regulator is brought back for in-house maintenance. Vacutron intermittent/continuous suction regulator from Allied Healthcare. This suction regulator is different from all of the suction regulators that I have done either repair or maintenance for. However, the functions still the same. The intermittent timings for this model having shorter range of time. The staff who is in charge for helping out in the marathon requested for an oxygen transport flowmeter connected with another small oxygen cylinder. Before loaning it to him, I have to check whether it is in working condition. Since there is no service manual or functional check list given to us upon purchase, we only able to roughly gauge whether it is still working.

103th day of attachment

In the morning, I did preventive maintenance for the Thoraric Drainage aspirator and ear thermometer as they are due since last month. After that, i continue editting my final report before letting my supervisor to read through it.

In the afternoon, I done a bit of repair since my colleague is on leave. I repaired a intermittent suction regulator and analyze the problem with the alternating mattress pump cotrol from betabed. After that, i was being assigned a task which involved in checking of devices required for the marathon event, Philips Singapore Cup (11-13 August) . However, I only managed to complete the checking and preventive maintenance for transport physiologic monitor, Propaq 202EL.

102th day of attachment

My colleague and I continued doing preventive maintenance for the Clinic C for maintenance and we managed to complete all Slit Lamps, as other remaining devices required servicing are located at polyclinics. I did some paper work such as scanning and transferring scanned documents to the local drive or folders.

There will be a talk at 12 – 1pm at the idea lab located near the cafeteria. The talk is held by Olympus. The speaker is Regina from Endoscopy. She talks more of the latest technologies of the endoscopes. The area that I am very interested was the endo capsule that is about half the size of our pinky. The whole process of diagnosis takes about 8 hours and most of the patients would not want to stay in the hospital for that long, as they might be busy. The capsule is about to adjust the brightness automatically. I believe that it is one-time usage as the way to remove the device is to pass motion after the test is done unless they have a reagent that able to sterilize the device.

After the talk, my colleague and I went to Clinic C to redo the preventive maintenance of the Slit Lamp again as we want to regroup the electronic table and tonometer under the serial number of the lamp. It was kind of rush to perform all the maintenance as we are limited to an hour before patients start coming in. We managed to complete around 10 Slit Lamp. However, there is still much maintenance to be done in Clinic C.

We did not return the repaired devices today since there are not many devices were sent for repair lately.

101th day of attachment

My colleague and I started preventive maintenance earlier than our usual timing as the Clinics will start at 9 am. However, there are patients at the clinic even before the clinic starts its operation for the day. We will only managed to perform preventive maintenance at certain few timings that are before 9am, lunch hour and after 4 pm. There are fewer patients and easier for us to perform it. We managed to finish doing the preventive maintenance of the Slit Lamps in Clinic C.

In the afternoon, we went back to Clinic C to do the tonometers that located near the Slit lamp and the A/B scan which is used to detect any retina tear by making used of sonar. We also went to clinical measurement clinic (Clinic F) to perform preventive maintenance for HP defibrillator that has 5 tests to be done which defibrillator calibration, energy delivery and etc. At 3.30 pm, we will be having a briefing about the dialysis machine. The briefing is approximately an hour and talking about the safety features including the common problems or faults. However, there is a flaw with this Model, as the solution used to dilute the solid salt will be kicked easily.

100th day of attachment

We start going to the various patient wards to focus on our preventive maintenance for the month. For this month, there are more devices under warranty and contract. Therefore, not many devices required in-house maintenance or other maintenance. If we are done with the preventive maintenance with the wards, we will be going to various departments such as X – Ray.

Most of the equipments that we have done so far are nebulisers. In the afternoon, we will be going to Clinics, X – Ray and endoscopy department for preventive maintenance. I feel that we are able to complete most of the preventive maintenance for the month. However, Clinics are too busy for attending the patients that allow us having difficulty of doing the maintenance as we are not suppose to do the maintenance in front of them. My supervisor told me that engineering technicians and me would be attending a short briefing about the operation of a dialysis machine that just commissioned. The briefing will only focus on the operation sector of device. The briefing will be at 3pm in the afternoon by the service engineer from that vendor.
