Wow, month of April is ending in a few days' time and most of the preventive maintenance are done. There still a few more devices for preventive maintenance but they are not located in the hospital. instead, they are in woodland polyclinic so Lee Chong went there to do preventive maintenance while i chose to stay in the workshop to do more of repair as i want to learn more in depth for repair.
I took a mattress pump control to fix the problem which is one of the tubes on the connector broke off. Before gluing back the tube, Lee Chong told me that i have to check for the strength of air flow by putting your fingers on the opening of the tube and a hissing sound will be heard. If the sound is very soft, the pump required to be changed as the air pressure decreasing ( pump exceeding the lifespan). Therefore, i changed the pump and charged it on the work order to have a record of what i used from the storeroom. He told me that the stepper motor will turn until a point that two openings are closed and no air will be blown out. However, the motor will still continue turning and release air at one opening. This is one of the method how alternating airflow works in mattress pump. Another method is one of the opening will close slowly while opening the other slowly.
After lunch, Faz gave me 4 devices for simple repair. They are mercury manual sphygnomamometer, single flowmeter, transport flowmeter and opthalmoscope. Firstly, the fault for mercury manual sphygnomamometer is a small amount of mercury is stuck in the middle so i keep pumping and releasing the air from the cuff in order for the amount of mercury to flow down. It took me about 15 minutes to solve it. Secondly, the inner glass (O2 meter) of single flowmeter crack. The store have a smaller meter instead of the one i need to replace with so i change the knob and casing. It is funny as i could just change the whole thing instead of fixing the separate parts together. However, i have to use back the O2 probe as it costs 2 times the price of the flowmeter. Thirdly, the fault lies with the transport flowmeter is the glass cover for the gauge, which measure the amount of oxygen in the tank, is missing so i have to change the whole gauge for them. Lastly, the opthalmoscope unable to light up despite charging for a long time. When i switch it on, it is really unable to light up so i have to check whether the battery is faulty. Therefore, I charged it overnight to make sure it lies with the battery.
