Meet William at commenwealth at 8am sharp as the appointment in SGH is 830am. Early in the morning went to SGH operation theater to service an IABP pump system97. The reason why we have to go so early is because the operation theater has cases at about 9am and they will be extremely busy and nobody will attend to us.
so we reach there earlier than appointment time and quickly service that pump. luckily the maintenance service this month for this machine is a minor one and so the test and checks we have to do will be simple. this IABP system 97 pump is an older version than system 98 and has no auto modes to check internal function so we has to do it ourselves.
We did a electrical safety test and also did a few simple checks for the machine. William told me that if it is the major PM then we will have to bring the testing equipment to test. IABP pump have regular checks every three months and minor and major is alternatively.
this machine belongs to type 1 class CF (cardiac floating), that means the machine has direct contact to patient's heart.
Next stop was NUH. we did two ventilator by SIEMENS servo 900c. they are the older version ventilator which meter runs on analog system. so far i have not seen servo 900c before and it looks quite new as the hospital had hardly use them. i think is because they have got the newer version of ventilator and this model isn't that user friendly.
pics:
( Ventilator servo 900C, looks old rite? xD )
( i had a hard time testing this machine. =.=' so many knobs...)
( oxygen cell... i think this one cost 3 digits ! 0.0)
Morning went to NUH for William's project meeting. then after the meeting went SGH to do perventive maintenance for IABP system 98 pump. first time i am exposing to this pump after reading the manual.
as usual, William will clean the exterior of the machine. And i will do the Electrical Safety Analyzer test first.
I follow the checklist to perform the various checks with William teaching me how to operate the machine. this machine has quite a lot of test to be done but mostly is machine calculate the results so it is easier. the longest time is the battery test. we had to run the machine on battery till the machine shows low batt. a newly bought machine's battery life last about 2 hours.
but the machine we doing PM is bought quite long ago so the battery life is not that long. the whole testing process take us about 1hour 30min.
After lunch we went to KKH to do patient monitor. When we reach the OT, the patient monitors that we wanted to do PM are all on patients and the nurse told us to come back in 1 hour's time.
so we went to BME workshop to rest for a while. then we met another vendor. i forgot what's his name already but he is from drager company, IDS's competitor.
after waiting for an hour, we went up to the OT again. luckily now they have one monitor for us to service as they are very busy. so we swap one monitor for one after we service one so they can use at the same time. thats all the thursday.

( patient monitor that display ur heart rate per minutes, sp02%, respiratory rate, blood pressure and even temperature !)
(erm... what is this? argh.. old ventilator... sux big time...)
morning i report to office. William had to service the CUSA machine.
we did not know the fault at first but as soon as we started testing, William discover that the tester meter had the cable short together and burn the ultrasound PC board.
William had to change the board and test again. after changing the board, William had to service the test meter and make sure that the wire connecting to CUSA is not short.
He took out the cable, follow the line and make a new cable following the same connections. He soldered the wire together and put them back to the machine. Using multimeter to find out that whether the new wires has any accidental link or short to each other. small or minor mistakes can cause the whole machine to be malfunction and it is quite serious especially when the machine is new!
when the repairing work is done, we started to test the machine according to the checklist given. everything is within range and the machine work just as fine so we pack up.
it was about 1.30pm and we have not eaten our lunch. But we were too tired to move so we rest at the workshop for a while and went NTU to have our lunch after that.
after lunch we went to Ang Mo Kio's KK women's clinic for PM services on ultrasound machines. we did 2 ultrasound machines there and was really tired out after finishing the job.
pics:
(CUSA EXcel machine use to remove soft tissure in the body)
(hmmm.. ultrasound machine to scan for babies ! xD) this is a smaller version, function also limited.
tuesday went to SGH first for the commissioning of a Graseby syringe driver. after that went to alexandra hospital to do preventive maintenance on a suction pump. we went to clinic F to retrieve the machine and bring it back to Alexandra Hospital BME to do the testing as there is no place in the clinic to test. while doing the battery test, we found out that the battery is totally flat so in the jobsheet must write change of battery needed.
last stop for tuesday was Raffles hospital. they had some problems with the networking again. this time the ALOKA guy, sam, came as well to configure the computer to the (ultrasound)ALOKA machine.
they realised that one of the cables was missing and therefore cannot transmit the data over to the other end so the sam has brought a cable and replace it and the problem is solved. sometimes is not just any cables that looks alike can be connected to the system, we must read the manuals and see whats the internal wiring of the 16/32 pins cable are and the directions to connect them is very important.
morning meet William at Yio Chu Kang mrt as we are going mount alvernia first.
William drive to mount alvernia hospital to return Mr loh (IDS engineer station at Mt A)the test equipment for the Mammotome machine which consist of all the tubings. then realise that he haven reach so we put the equipment on his desk and left.
after that we went to Mount Elizabeth to get the test equipment for the CUSA EXcel machine. i can still remember that the first day i followed William to Mt E for the commissioning of CUSA and it failed. so the machine was sent back to our office waiting for William to troubleshoot and solve the problems. Being an senior engineering is not as easy as i think because the responsibility is there and people's expectation will be a lot higher. after retrieving the test meter from Manny (BME guy from Mt E hospital), we went to SGH to attend to a breakdown call. Ventilator servo I has an error message of 'technical error 28'. we did a pre-use check test and display screen showed that the internal test failed and also the alarm test also failed in a single check.
William had predicted it and brought along a loudspeaker to replace as he explained to me that the resistance of the spoilt speaker is lower than the new ones.
Loudspeaker's changed and passed all pre-use check tests.
Off to office to service the CUSA EXcel machine. did the test many times but it still failed. why ?
pic:
(instruction paper in the loudspeaker box that teaches you how to change the speaker.)
(loudspeaker located at the top left corner, can u spot it !?.)
friday went to changi general hospital to do PM services. then met diana at BME.
Me and William did 4 machines at CGH. the machine named fluidotherapy i think. haha.
need to test temperature only. (35, 40, 45 degree Celsius )
but each test need to wait for 20mins for the machine to reach that temperature. so in the meantime i just sit down there read magazine. yes, there are lots of magazines there. Got teenage, female, i weekly, wedding.... etc.. LOL..
then lunch time went to the foodcourt there to have lunch. Lunch at CGH is cheap as compare to other hospitals. the fruit juice is only $1 ! same price as Ngee Ann !
i MISS Ngee Ann Poly !!! argh....
pics:
(these are the machines we service on friday, Fluidtherapy)
(closer look at it, inside is filled with sand and is for you to put hand inside the flowing sand to blood circulation. XD)
morning went to NUH with William for his project meeting. he needed to go because IDS salesperson was not free. so we went NUH meeting to listen.
after the meeting, went to NUH BME department to do commissioning of an ultrasound machine alpha 10.
commissioning basically means to test and installation of the equipment which they had just bought from IDS.
alpha 10 is the latest ultrasound equipment and it has a range of better features comparing to the older versions.
while we were doing the commissioning, the salesperson came. after the commissioning is done, we pushed the machine to the site where they needed and 'install' the equipement with a external monitor that they have there.
Eva (salesperson), me and William went for lunch at NUS which is just 10mins walk from NUH.
KKH is our next appointment as William dropped Eva at Mount Elizabeth then to KKH. At KKH, we went to ClinicD room 5 to PM an ultrasound machine. that machine is an old machine but the functions it has have to be the same although the technology is not that excellent.
we did Electrical Safety Analyzer testing and function test for the ultrasound, using the probe to scan with a phantom and measure for its accuracy. When everything is done, realise that we still have time so we went down to TTSH to do PM for 3 Graseby syringe driver.
basically what we have to do for testing the syringe driver is test for the motor speed, motor accuracy, Occlusion ( blockage in tubing which carries fluid to the patient.
the range of the occlusion should be 3-4kg as we using a syringe like weight gauge for the driver to run till the motor stops. by right if we had successfully passed the test, we will go home on time but one of the syringe driver occlusion test failed so we had to calibrate and test again.
after finishing the three PM for syringe driver, it was 6pm. tiring day.
(Ultrasound machine normally used for scanning baby and can take measurement of the fetus.)
(see the box on the bed. its phantom. a testing box for scanning test)
(hehehehehe ! what are u thinking ? 0.o) LOL...
the condoms are to put on the vagina probe use to scan inside the women vagina.
morning at office reading manuals. i ead about IABP and it stands for Intra- Aortic balloon pump.
afternoon went to tan tock seng hospital. it was my first time being there. from office, tuan bring me and yip to tiong bahru for lunch then drop me off at TTSH for me to meet William.
Sit at the entrance waiting for William for very long. and finally he reached and we went to do our PM at breast assessment centre at B1.
William had poor memory as he could not recall the name of the person he wanted to look for so he called office to ask. proceed to do our pm inside a room after finding the person that we are looking for.
this time it is a Mammotome machine which William and i were first time doing it. The Mammotome System is for diagnostic use only and is not indicated for therapeutic use. Through the use of imaging methods such as X-ray or ultrasound, a breast abnormality or breast lump can be detected, even in its earliest stages. Using the same imaging methods, a physician can guide a Mammotome® probe into a suspicious area of the breast to gently collect the abnormal tissue through one small, ¼-inch incision.
The Mammotome® System also can be used for fibroadenomas (non-cancerous breast lumps). Millions of women can now receive care in a doctor's office with the Mammotome® System rather than having the lump removed by invasive surgery in an operating room.
the mammotome we do PM is from johnson & johnson brand.

time seems to past very fast today. william and i stay at Mount Alvernia the whole working day to sort out the paperwork there as one of the engineer from IDS just left that place. and he had some paperwork and PM services not completed.
checked through the files of PM services from May onwards all the way till Sept. that previous engineer has made quite a number of serious mistakes in his PM service and i shall not elaborate. Met stephen, the IDS boss, at Mount Alvernia in the evening, he came here to oversee things and tidy up the mess as well.
William ask boss to reserve me a place in IDS because after my attachment i can start work as full time liao. then the boss says he will reserve a place for me. then i said the time is still long to decide anything now, both of them laughed.
We went up to the sterilizer room and we have to wear the 'full armour' to enter. i am not sure what is wrong with the machine but saw them doing the leak test and went to the back of the sterilizer to check the air pressure.
its my first time seeing sterilizer and its huge! thats all for today. i went home from Mount Alvernia Hospital. It is located opposite Macritchie reservoir.
pics:
(went to opposite Mt Alvernia that Assassi home or day care centre to do checking of equipment)
(this is Oxygen Concentrator providing pure oxygen to patient) xD
time flies and it is already the third week i am being attach to IDS company. Learn a lot of skills from the senior engineer of the company, William. A special thanks to him for teaching me with patience and his enthusiasm.
today went to KKH to do perventive maintainance on five patient monitors. surprised that he willing to let me handle all five and he just concentrate on his paperwork. but of course he helped here and there whenever i am too slow.
we did the monitors till about 1pm thenwent for lunch at 'kopitiam' inside KKH. Nowadays most hospital has a lot of facilities. KKH even had a macdonald as they are specialties in women and children patients.
after lunch we went down to Thomson Medical Centre (TMC) to do the networking of the ultrasound machine. It is similar service compared to the raffles hospital's call. all we have to do was just type in the IP address of the server or printer that they wanted to assign to and configure for the 'store' button.
It looks pretty easy but William and i had to refer to the manuals and figure out some part of the config.
When the setting is done, the doctor ask us to standby outside as she took one patient to test out if the setting is what she requested. After TMC, we went to Mount Alvernia hospital to sort out some paperwork there.
pics:
(u know i know everyone knows whats that for !)
(One of the patient monitors i service today ! xD)

(close up shot of the ultrasound machine, model is Prosound 5500 SV)
its Friday, william had to go back office so i meet Ziyuan at jurong east MRT to take shuttle bus to office located at tuas. it is much faster than taking train to boonlay MRT and take bus 192 this way.
the shuttle bus arrive at 745am. before the bus reach to a complete stop, people already crowded around the bus doors. typical singaporean (kiasu), they are afraid that they could not find a good seat. then we reach IDS building about 820am.
morning doing some paperwork in office helping Tuan to stock check infusion pump at the work room at level 1.
weather looks bad and its lunchtime.so william drove us to NTU canteen 1 to eat. tried the western food there. it was not bad and its cheaper than outside.
first hospital we went to is SGH. IDS got a demo machine ventilator there having problems so we went to check it out. most probably is the circuit board need to change so william brought along 2 boards.
after installing the board, we did a pre-use test and it was successful. then we went to KKH to continue our PM with syringe driver. we had plenty of time and so william ask me to teach ziyuan and ruby what to do when doing PM for syringe driver.
the steps to follow on the checklist for syringe driver are quite simple and they can easily do the PM with very little help from me.
finishing with the two small syringe driver, me, william and ziyuan went to Raffles hospital saying goodbye to Ruby.
the manager of raffles hospital BME department called william for help to set up the networking system of the ultraound machine to link to the main server so as the images of the patients will be sending to a common point in the hospital.
we waited outside the room as there was still patient inside. we saw a coffee machine and william ask us to take a cup of coffee each as it is free of charge. while sitting down on the sofa enjoying our coffee, we saw many pregnant women accompanied by their husband waiting for check-up.
then the manager called us into the room to set up the networking system.
after a while, william realized its 530pm and see us off.
this morning meet william at commonwealth MRT and we went to NUH. william had to attend a project meeting at NUH so u brought me along to listen. after the long meeting, we went for tea break then went KKH to submit PM forms.
william drove me to toa payoh to have lunch after that. Mount Elizabeth was the last stop for today.
we went to critical care unit (CCU) to PM a patient monitor. the air conditioner there was like 20 degrees. so cold la. oh ya. while i was doing the testing on the patient monitor, realised that the ECG leads got blood stain. it was so dirty and william could not stand it so he take paper with alcohol and wipe till clean and we wore gloves.
after that write report and submit to BME.

hello. today was a boring day because i had to report to Mt alvernia again as williamstill have a half day training on medical equipment. i stayed in Mt alvernia till about 3plus pm and william came fetch me.
morning reached Mt A. at 840am. the IDS engineer station there have not come so i read some manuals and mr toh from BME taught me about infusion pump and electrical safety analyzer. it feels like a long day reading manuals and doing paperwork. i was asked to arrange the files and number the PM list done according to their number shown at the master list.
after that went for free lunch there as they gave me the eating coupon. the people there are friendly and the environment is very good. but one thing not that good is the size of the hospital is too small.
its 4pm ad william fetch me to Aloka company located at harbour front building. the first thing you will spot when you step in is the ultrasound machine. they are testing on the new model of the machine which they have not yet released to the market.
i took a few information paper about the older version ultrasound scanner used in hospital now. william drop me off at Outram Park MRT after that and went home.
pics:
(when i going work that time take de.. morning sun so strong! argh !)
today william did not fetch me to work as he got a one and a half day training to attend. so i took bus to Mount Alvernia hospital located opposite macritchie reservoir. reach there a little early so sit down and read machine manuals while waiting for mr loh to come. he is a staff from IDS and will be permanently station at Mt Alvernia.
so the whole day i help him did paperwork and helping out a bit in the syringe pump testing. its a boring day without traveling around in car.
ohya! one more thing. sent darling to sch in the morning XD
yo !hmmm... tired day i would say because today do many equipments XD
this morning william meet me at yio chu kang Mrt 830am. it was drizzling, william drove carefully. we chatted in the car while he driving towards KK women and children hospital.
we reach KK hospital, went to level 4 to their BME department. and guess who i saw, ruby (if i didn't spell wrongly), my classmate whom attached to KK hospital.
okay, did 4 patient monitors mostly on my own and william's help. also did about 4 syringe driver. so we went for lunch later than usual at KK hospital's 'kopitiam'. as we cannot finish so many machines so we complete them after lunch. after KK hospital, went to Thomson Medical Centre to change the ventilator's oxygen cell. now then i know that the oxygen cell of the machine actually cost few hundreds. never did i know such a small thing can cost so much. after work william drive me to Mt Alvernia to meet a guy from IDS also and i will be following him tomorrow as william will be having a one day training.
i think thats all for today!

oh ya.. about the friday nite riding.. we ton at town with our bikes as usual. but going to tampines in the morning to see the race !
it was raining at town at about 4am.. so we slack around play around...
slowly ride to tampines in the rain when it gets smaller or not so heavy.. *riding in the rain not fun hor.. LOL
reach tampines drenched. cycled along Mrt track from kallang there onwards ba..
hmmmm.. then reach tampines see my friends race. the race track was basically man-made except for the grass below. LOL got stairs made from planks and logs.. its an obstacles course and 2 persons compete at a time see who reach e ending point 1st.
after that went frenz house take bike bag and took MRT home ! wtf? yes ! MRT !
its a friday ! which means at nite i can go cycle already. haha.
ok morning i and william went SGH to check out the ventilator machine's battery life as the last time we saw it as 0% so we leave it to charge for 2 days hoping the battery can be charge up. the ventilators at SGH are new so next time when doing PM or service testing its easier as there isn't many knobs and it has a touchscreen !
the battery was charged up fully when we arrived and so william did his paperwork and let the customer sign.
went to KK hospital after that to do PM on ventilators. yes its ventilator again. the machine has so many knobs on it so the testing process is very tedious and time comsuming. so theres two machines need testing and calibration, william did on machine while i did the other one. took us quite long to do these two ventilator. after this we also did a PM for patient monitor.
went for lunch quite late. receive service call from thomson medical centre. had to service ventilator again. and they have two ventilator. but one of them is newer version. reached there, check out the two machines and realise the newer one has the oxygen cell problem. william say the oxygen cell has use finish thats why during the pre-use check the system indicate the oxygen cell check failed.
thats all for the day. i'm tired.

(ECG waves interpretation chart)
(the patient monitor using a analylizer to test and simulator to calibrate)
as usual, william pick me up at mrt station and we headed to alexandra hospital. did Preventive Maintainence for ECG machines. its just a regular check and testing on the machine. we use the safety analyzer machine to test for leakage current all those. and the ECG machine got 10 leads so all the leads were attached to analyzer to test and after that we did a simulator test where the simulator can set to a certain heartbeat per minutes to compare with the ECG machine and print a report for evidence and report writing.
afternoon went to KK hospital to change the battery of IABP balloon pump machine. it consists of 2 twelve volt batteries, which means the battery is big. as the BME personel do not know how to change the batteries, they called us.
next went to Mt Alvernia to do PM for ventilator machines. 2 machines there to do so william demonstrate 1 machine and ask me to do the other ! i was a little bit scare to try but he got a manual for me so i just have to follow the manual. the test was very tedious and i was very slow because its my first time doing it !
(ventilator - use for breathing ! this machine act as human lungs and help in inhalation and exhalation)
(full view of the ventolator machine)
(having lesson by william the senior engineer)
(lift door of Mt Alvernia hospital) Hello...
day3 for attachment today. sian of blogging so long liao so today shorter post. ha. XD
Same as yesterday, William picked me up at MRT station but today at commonwealth. then went to Singapore General Hospital. William asked me to assemble the ventilator machine, following the other sample that he assembled. he guided me along and the machine is assembled ! then he teach me how to do the machine testing. he did for 1 machine and other 1 was done by me. actually quite easy to do the testing as the test all done by computer. what i have to do is just do the setting and follow what the computer instruct me to do. very fast we finish the 2 machine testing. i met mr lee, he has been working in SGH BME for more than 30 years. think he is the 1st few batch of BME in singapore.
went to mount alvernia in the afternoon to standby. also had a lecture there. william explain to me how cusa works and how ventilator works.
