The first thing i ever did for the day was doing function test for the STC-503 Terumo Infusion Pump which are the usual few tests. I tried to align the rod with the screw together but always able to align it temporarily so went to ask my colleague for help. He succeed in repairing the jammed tubing clamp. seems pretty impressive though as Faz tried for an hour yesterday. While testing the flow, there is noise generated around the stepper motor area. It seems like there are friction between the teeths of 2 gears. This will disturb the flow delivered to the patient and the accuracy of the device. The only solution is take the stepper motor out of the device and aligning the gears. After that, you have to fix it back to the other parts and turn it on to check whether there is any noise. If there is, repeat the process until the gears are moving fit in nicely and moving smoothly. Before doing all the above, i have to clean the gears, "fingers" and ball bearings. It took me close to an hour to remove the stains made by glucose and grease. It was very difficult to remove the stain especially between the teeths of the gears. i tried using the scrub but it removed a bit of it. The alternative way of doing it is using tweezer and alcohol pad to remove them.

Continue with the preventive maintenance.......
I was being asked whether i have done the function test for STC-508 which is the second generation of the infusion pump. I did not really know whether there is any different settings to be done for the test. To my surprise, the settings are the same as STC-503. The only difference in doing the function test for the pumps is the location of the components for occlusion and flow adjustments. the component for the occlusion adjustment located on the top of the device after you dismantle it. It is called VR2 which is the middle potientiometer. while, the component for flow located at the back of the device and it is also another potentiometer. STC-508 using microprocessor.

Did commissioning of a dialysis machine in the MICU with transmedic. The differences between this and the latest version of it are the latest machine has colour touch panel and more idiot proof as it has step-by-step instructions for the user to know the placing of tubing and etc.
