Hi,I am working on an infusion pump design. Would you please provide your opinion on the following two issues. Because we all have different point of views, I would like to get experts' opinions on these issues:1) Should Power button be combined with Stop button or should they be separate?When they are combined, pressing and holding the button will turn off the pump. While infusion is running, clinician will press this button to stop infusion.When they are separate, clinician will press Stop button to stop a running infusion. If they press Power button while infusion is running, they will get a warning message but it will not turn off the pump or stop the infusion.2) Should the light that indicates a running infusion be blinking or be on continuously?When you see a flashing light (possibly green), would you think that the pump is running or would it lead you to think that it needs your attention?Your help is greatly appreciated.
