[IP] Filling from the pen, and Disetronic cartridge volume...
2 for one this time ;-)

I don't know specifically about the Animas carts, as I currently use a
Disetronic HTron, but I can say that I HAVE filled those cartridges from a
pen. It's not elegant, but it works: pull the plunger out from the
cartridge, and set it down somewhere STERILE (like the inside of the
just-opened cartridge wrapper); put the cap on the other end of the
cartridge; SLOWLY squirt insulin from the pen into the cartridge (if you
try to do this quickly you'll get a LOT of air in there!); replace plunger,
remove cap, carefully tap out any bubbles that formed.
I would imagine a similar procedure would work with the Animas cartridges,
but I haven't seen them. YMMV, I don't take any responsibility if you try
this, blah blah blah.

Yes. I suspect the actual volume of the D cart is more like 350 units, the
315 figure is "useable" volume. Notice how at the top of the cartridge
there's some dead space where the plunger can't reach, I think that's where
the "lost" insulin goes.
