so fast, it is 25/9 already, i almost work as biomedical engineer in the hopsital for one year.

today i go to dentist clinic to watch a service engineer to service the Kavo Dental Chair unit made by Gallas, it is actually a quite nice dental chair. one type of germany product. 

imagine when i was young, i used to sleep on the dental chair until it finish.now i realize it is such an expensive equipment, inside has a lot of complicated circuit. The engineer Boon talked about having a cover on the button, (same thing happen in OT), hygiene is first priority wherever it is in contact with the human blood. when the blood begin to dry, then it will be become clot, which is harder the casing, it will cause damage to dental chair. It is under contract service, when the engineer do the service, he changed the O ring and washer, those easily under wear and tear to keep the machine fresh. One thing worth to mention is that when a contract signed as rm 20000 for two year PPM servicing, it means every time the company come to service, hospital will pay rm10000 for each service. When hospital signed the contract, the company will automatically discount 20% for the spare part, provided that not extra charge will occur in breakdown call. somehow, i think it is good for so many company come hospital to service, so i can learn from them. Quite interesting actually. 

Today help to repair the decotion machine, unexpectedly that when you use level bar to meaure the level in limited space, it do not work. you can use spanner thickness to measure the height of the hole. if every part is the same, then it means it is in balance condition. 

Futhermore, today i learn to repair chinese ward the sealer machine. The easily spoilt part, as taught by Mr.Leong, is the micro switch damage and the bottom wire spoilt. It is actually quite a lot work to do. 

tomorrow going to find samsung to repair tv. at the same time, hoping the weighing scale excel company will come to calibrate the weighing scale. 

hope everything will be fine tomorrow. 

all the best .

p/s: realize there is one company called lifeline selling the wheel chair spare part.
