Re: [IPk] no delivery and knots



Hi All,

It takes a very VERY tight knot to block the tubing - you should see the
problem when we try to simulate a blocked catheter with all sorts of knots
and clamps to seal the line tightly.

It is marginally possible that a really knotted tube would restrict the
line, but if is was so severe to affect delivery you would eventually get an
alarm. This might be a little slower than for a completely blocked line.

In general you will get a blockage alarm when a amount between 1.5 and 3.5
units of insulin have backed up in a blocked line, and at low flow rates
this can take a few hours to appear (Or the equivalent amount of delivery
time if you allow the syringe to become empty - The 508 has a volume alert
to overcome this).

This is not the 'official' Minimed line just my experience on these things.
