hi,

just wondering if anyone out there has tried the disetronic
"open system" pen ?

They actually have two of them, altough only one actively
marketed in the USA. One use 3.15ml reservoirs (same as H-
pumps), the other use
3.0ml reservoirs (same a D-pumps IIRC).

In theory it is a good idea, however whatever money you may
save by filling the reservoirs yourself, you lose because
the @$#@$ reservoirs are so expensive. (About $3 each), so
while 3ml catridges are about 50% more expensive then 10ml,
the Disetronic reservoir price adds about the same amount to
the cost of what you mix yourself.

There is one other little gem in Disetronic pens you need to
know about. T comply with Common Market (CE) calibration
requirements, the pens will stop working 2 years after you
start using them. The LCD panel that displays the does
flashes for about a week, and then goes out (and another $85
goes out the window)..

thanks matt for the information. one more question, do (did)
you find the pens reliable ?

i am not that concerned with saving money using the pens,
but rather convenience. in addition, any clue if Ultralente
will work in the pens (due to particle size) ?

They are reliable until the clock runs out (I have
both flavors).

UL won't be a problem. UL particle size is still very large,
even compared to a 31 gauge neele, which brings up one other
little gem.

Normal Pen needles don't fit the pen sold in the USA. You
have to buy Luer Lock needles, and your local pharmacy isn't
going to stock them (although price wise they are about the
same as pen needles).

The uncommon pen, which uses the 3ml reservoir, takes a
goofy needle, Pen needles sort of fit, the diameter is
right, but the screw thread isn't. Disetronic does make a
slip on pen needle which does fit, but due to another bone
headed move by Disetronic, most of the pen needles turn out
to be prescription devices. How or why the FDA did it, I
will never know, because I looked up the 510(k) and found
the approval was based upon therapeutic equivalence to the
BD and Novofine needles, which are over the counter. So go
figure, it is equivalent to a product that is approved for
OTC sale, but only as a prescription device....

And you wonder how they got into trouble with pumps?

matt, again thanks for you explanations. you have helped me
a great deal ....
