[IPk] For Sara WAS] bubbles bubbles bubbles!!!


If this "bubble" is at the bottom of the plunger then its NOT an air bubble .
 Bubbles rise. I think that you could be looking at the actual plastic structure
of the reservoir itself.

 Its not an unreasonable error to make as it looks pretty like an air bubble
viewed thought the reservoir when there is only little insulin left.

We inject air into the insulin vial before we fill otherwise when you are
pulling on the plunger and removing the (liquid) insulin, then you are creating
a vacuum in the vial and the reservoir.  Not only does this make the insulin
harder to draw up, but may distort the O rings around the bottom of the plunger
and actually drawn in air in round the bottom end of the plunger.  In your
manual it should explain exactly how to fill the reservoirs.

Have another look at one of the reservoirs just after you fill it and then look
at it again when you remove it from the pump before another refill.  See if you
think that the "bubble" is part of the structure after all.  I thought this was
a bubble when I first saw it, it looks just like one when the reservoir is
