Actually, today marked the start of my june's preventive maintenance. However, there is some complications of the list of devices due for maintenance. Some of the devices on the list had done maintenance 4-5 months ago. I feel that the system generates the work for it as the system is not being updated of change in schedule. Therefore, we did repair for the whole day.
We got informed by a staff nurse from MICU that the result of temperature test for blood analyzer indicates failed. Temperature test is always required to be done before inserting the cartridge of patient's blood sample. Different temperature varies the accuracy of the result. The temperature test is checking on the atmospheric temperature. We did the electronic component test and it also indicated failed. we initially thought that may be the connector and the temperature card got contaminated by the blood stains as we saw the trace of blood on the device. We wore gloves to clean the devices that dealing with blood samples to prevent any transmission of diseases. After cleaning, the analyzer indicates sensor error after inserting the temperature card so i feel that after thoroughly cleaning will make it worst? Lee Chong even went to SICU to get another temperature card to check whether the problem lies with the card. That's what we called troubleshooting. After several of failed attempts, we tried using a new edge connector to check whether the problem lies with it. We spent close to 1 -2 hours in finding the problem. After i inserting the temperature card tightly with the connector, the result of both tests indicates passed so most probably the contact is not really good or blood stained on the sensors. The most common problem is the spinner lost. It is used to keep the roll of paper in place. However, it will be thrown after the roll of paper had finished.
I got to see a therapy unit that exercise and encourage blood circulation of patient's legs. It is called passive motion unit. It was being sent down to the workplace as it was unable to turn on. We still trying to analyze the fault before making any decision of buying a new component board or microswitch.
