Out of all the faults we encountered from different devices, we as a team decided to work on the suction pump. This was so because they have a few of them and they happen to be some of the most important machine being used in the hospital which are prone to damage.

Problem: The fluids being pumped can sometimes overflow into the pump when the bottles are full hence damaging the motors windings. This can happen if the Nurse giving treatment is not monitoring the process of sucking.

Solution: We spent most of the times in the library this week researching on possible ways to come up with a low cost overflow control mechanism. The research took some days because we specifically choose a control mechanism that lies outside of the suction bottle. The suction machine can be used to suck different fluids from human body of which it would not be hygiene to be placing a sensor inside the filling bottle.

So the best solution we came up with is to use infrared sensor. We plan to start designing it the upcoming week and do some testing.
