22th DaY of atTaChMent
Trying my best to figure out the problem that cause the suction regulator unable to turn on by itself when swtiched to intermitten mode. After 2 hours, my colleague just assembled the whole devices by screwing back the screws. Surprisingly, it works and we just have to adjust the duration for the "off" and "On" mode. Transmitten mode range for off is 7-12 secs and for on is 15 to 20 secs. i like to correct what i said about the devilbiss suction unit. It is an aspirator which has the similar function as suction regulators but it is electrically powered and has a compressor in it. Both of them have the maximum pressure of -300 mmHg for wards and intensive care units as they are used to clear the airways. However, in operation theatres, the maximum pressure used is -760 mmHg. The reason of using such a high pressure for vacuum is to suck the blood, tissues and etc during a surgery.
There is a commissioning of 2 equipments on trial which are automatic lensmeter (CLM-3100) and automatic projector. automatic lensmeter is used to measure the power of the lens which we also called the degree of refractive of the lens. The projector is used for eye check up like asking you to look at a few letters and asked you to identify the image. This projector has more than 40 templates of images which varies from alphabets to images of animals. May be i should try to operate the devices tomorrow to get a better understanding of them and their operations.
Mr Toh briefly told us the ISO auditing which is held every 2 - 3 yrs. Employees will be asked to answer questions about safety such as fire safety. There is a Lock- Out safety which talks about what you should do if the devices is faulty.( nurses have to put a tag that "says do not use" and stating the problem on it or use a electrical lock-out if the cable is unable to be removed from the device). He also talk about the preventive maintenance of the weighing machine for lab and pharmacy. We have to do 3 tests for it which are linearity, repeatability and weight loading ( to know where the load cells are placed). It is using a vacuum fluorescent display which emits light and consists of fluorescent tubes bent to the same of the 7-segments. It uses high voltage to ionise the air in it to allow it to bent. LED 7 segments also emit light. However, the LCD display absorb light which is used for the calculator display. It is cheaper than the vacuum fluorescent display and do not use much of energy.
