At site change time I noticed a strong smell of insulin in the pump's reservoir chamber. I can actually see some insulin in there, as well drops hugging the inside of the used reservoir (below the stopper). (This has happened before.) Really annoyed. Letting the punp dry out now and I have switched to a different lot of reservoirs. Anyone else have this problem? I imagine this can't be great for the pump -- getting wet with insulin repeatedly. Has anyone found any residual effects from this issue?
