Fourth day of my attachment!!! Loving it!!!

The first thing that i did in the department todae is trying to get a feel of how to do the occlusion and flow test for the infusion pump by using a infusion device analysis series ( a testing device for infusion pump). I tried to do some troubleshooting before doing the test for the pump. Mr Toh told me not to touch the internal components of the pump when it is on as a huge current is passing through the device. i realised that the a mesage "Er3" is indicated on the pump. I did not have a clue what error was that so i went to ask around and they told me to the service manual has the answer to it. i went to flip through the pages of the service manual and found out that "Er3" means error 3 which indicating to the user that the air in line detector is dirty. i went to clean it and i solved the error. after that, Lee Chong and i did the preventive maintenance as it has to be done once in a year. Infusion pump belongs to the Class I and type B so we have to use the probe to place on its ground after the plug of the pump placed on the device test analyser. The analyser is able to print and transfer the record of the leakage current test to the computer.

I was being taught how to transfer the signatures that we collected from all the staff nurses after returning them the devices to the computer. It is pretty tedious as you have to name each signature according to the work order code of the devices.

There are two new equipments that were brought to Alexandra Hospital. one is on trial while the other is bought by the hospital. it is like a great exposure to new devices. i finally get to know how commissioning is like. the vendor will send a person to the department, test the equipment and tell the technician or engineer how it operates. The two equipments are ultrasound scanner and a device that able to do fine operation on patients. These two equipments are pretty interesting. one of them is like having a colour touch panel. I got to try a ultrasound therapy unit. you will really feel the heat generated by the device. It is like quite fun.

I just found out that not only resistors have colour code, the oxygen tank also have colour codes (for example: blue for nitrogen). Different type of oxygen tank has different positioning of the pins ( the distance between the pins) to let the user know which type of oxygen flowmeter is able to use for releasing the tank to supply the patient with it. In hospitals, the have a central control system that supply air such as pure oxygen near their bed which uses a wall attachment. It is pretty similar to the oxygen tank as it has colour codes to let you know wat air is being supplied and the locking device of the attachment varies with the type of air.
