[IP] RE:Animus Pump problem
Thanks for the evaluation of the Omnipod.. very valuable. This is stuff
Omnipod won't tell you about, nor will any of the healthcare folks tell you
I have an Animas 1250 too and it has some problems in certain circumstances,
which I deem serious. Animas hasn't done anything about them because it's a
programming issue within their firmware of the pump itself. Being a firmware
programmer myself, I know these are not easy to fix.
I am reaching out to the Animas users in this group if they have found this
particular problem which annoys the heck out of me... Here it is -
I set a bolus of 4.25
The pump bolused 0.25, then 3 more units, when it stopped and claimed an
The pump firmware says I should disconnect the infusion and
I check the IOB value which shows 3.24. I need an additional unit to get to
the 4.25 I selected The pump shows 88 units left in the cartridge, which means
it started at about 91 units before the bolus began.
I select PRIME, then continue and immediately release. I
hear the pump bolus for one unit. The total shown on the pump is now 87
units remaining in the cartridge. It shows 0 units were primed (which is
since the total has moved from 88 units down to 87.
I believe the pump firmware needs to be fixed to be accurate and reflect
what the pump is actually doing.
First, the occlusion detection was false. I have seen this happen
periodically. My guesss is about every 2 months, it claims an occlusion
during a bolus.
Secondly, the report on the priming is inaccurate, which would make an
important difference if... I did not disconnect. Since it would have
delivered an additional unit of insulin but was not accounted for.
I know.. Animas would say you "should disconnect" but not all infusion sets
are of the quick-set variety and there may be a good reason not to disconnect,
especially if you were not home, had access to all the supplies you needed
etc. It's annoying because when you PRIME, you can't set the amount to do a
PRIME function. You have to hold and let go at some point... not a wise thing
if you are connected.. That's why you "should disconnect". The problem is in
the firmware where you shouldn't have to do this step.
Conclusion: The firmware needs to be fixed.
