I never see anything on this group about pumping
insulin, so I thought I would post.
I just wondered if it was just me, or do many
other people have problems with their
pumps, reservoirs, or infusion sets?
For the last year I have been using a MiniMed 712
pump, and I have tried all of
the available infusion sets @ various canula
lengths, and had nothing but problems.
The pump rep recommended one type of set, and knew
nothing about the other sets.
In fact she wasn't even diabetic.
Some sets go in at a 45 degrees others @ 90.
lengths are 4mm-10mm. If you don't
have the perfect length and angle, it won't work.
What happens most all of the time is, I get air
through the bottom
of the reservoir and shortly after, it makes it's
way through the tube.
When there isn't air present in the tube and I
take a bolus for a small item like a
piece of candy, and do that 5-6 times within that
hour, my sugar goes high as if
I didn't take any insulin. On the other hand if I
just take the required dose for
6 pieces of candy at one time, it works fine.
In short, small boluses seem to be inaccurate and
minimed reservoirs leak air.
Last week I changed pumps to the Animas IR1250
which uses minimed infusion
sets, but the reservoir is made by animas, and
seems to work flawlessly.
(it's waterproof too!)
