I will have my final touch on the device by have the necessary tests which are the usual flow and occlusion tests to ensure the accuracy. I have to be meticulous dealing with medical devices.
After doing the tests several of times to get the readings within the range stated in the service manual, the tubing clamp seems to give me problem again. The clamp do not seems to close when i close the door. The clamp will close to stop the fluid from flowing once the user close the door. There will be a "ta" sound and that's how i differentiate whether the clamp is working. I bent the rod with a plier but it seems that the rod will not align with the screw after i close the door for the third time. We will try to open and close the door for 10 times to ensure the rod and screw are secured and aligned properly. I tried all means to align the rod and screw including adding silicon gel to secure it. Thankfully, it works by doing that. After running the tests for the last time, i concluded that it is working fine.
There was a commissioning for rehab devices such as treadmill. The vendor, Dynaforce sent to maintenance engineers down to do the commissioning. Actually, they came a week ago but they were clueless about the proper checklist of tests they are suppose to do and the safety class type for it earlier on. The leakage current test can not be done as it required taking the module out in order to test and definitely there will an amount of current leaking. There will be two metallic plates on the handle that have sensors beneath it to detect the heart rate of the patient. Heard from the vendor that it is more difficult to sense the heart rate from female as they have higher fats percentage. Some treadmills are running on DC while others running on AC. There will be more current leaking for DC compared relatively to AC. While it is running, a bigger size person holding back on the track, the current will flatuate like crazy. Therefore, i concluded that there are lots of factors to consider for the current leaking. After discussing with the vendor, they will give us more detailed checklist and the tests that done in the factory at Hong Kong.
