[IPk] new to pump and all sets failed so far!
I've been using 6mm quicksets with MM508 for the past 2 years but have not
experienced the problem you are describing.
I've never inserted a quickset without using the insertion device - I'd find
inserting it manually difficult - infact I'd switch back to using my novopen
sooner!! (Infact I recently bought a spare insertion device to make sure that I
dont have to do it manually!)
Haven't ever noticed having an "indentation" mark left at the insertion site
myself. Can only suggest that (if it's a 'straight line' mark) maybe the
catheter didn't enter the skin but was lying against the surface. If it's a
circular mark that may be normal - to do with the plastic part of the quickset
that lies against the surface of the skin.
Do you "pinch-up" the skin at the injection site before inserting the quickset?
That might have something to do with it - the amount you pinch up the skin will
determine the depth the needle&catheter penetrate the subcutaneous tissue.
I have only ever experienced the catheter becoming bent if it has gone right
through the subcutaneous tissue and is pressing against my muscle. When this
happens the set is uncomfortable and although the tube isn't completely blocked
only a small amount of insulin can be bolused at a time (ie approx 2 -2.5 units
will pass through before the occlusion alarm will go off). If the catheter is
bent the alarm tends to only go off if I've set the pump to deliver a bolus of
more than 3 units. So if Findley is on a small dose of insulin it might not
cause the alarm to go off - but could still delay the delivery of his basal
insulin - just my thoughts on it YMMV
The first time I injected an infusion set I used the 9mm quickset - it went
through my subcutaneous tissue and pressed against my muscle - I could feel it
and it was VERY painful when I moved/walked. When I removed it the catheter was
bent - in my experience the catheter only ever bends if it is touching against
my muscle. Insulin will pass through when it is out of the skin (like you
observed) but while it is inserted if the tip is against the muscle the insulin
will not, or only very slowly, pass through.
Cant really see what difference freezing the set will make -and anyway it's not
designed to be used that way.
Hope things work out for you soon,
best of luck

Findley had his pump fitted yesterday afternoon, its the Minimed 512. We
were not provided with an inserter, but that is now on order.
The nurse inserted the set, a 6mm quickset. After 4 hours his blood sugars
were still rising, I changed the set. The one I took out had left a very
small line indention in his skin. I put the second one in and after I did
the fixed prime it showed 'delivery failure' on the bolus dose, which was
done straight away.
When I took
this 3rd one off I did a bolus without it attached to Findley, and I could
see the insulin dripping off the end, so even though there was bend in the
end the insulin is getting through. The site where I had taken the set from
was completely dry, although again there was this small line indentation.
The nurse has sugessted putting the sets in the freezer, which I will try
when he is home from school.
