A couple of months ago or so, I noticed that my pump had some cracks on each side of the reservoir window. I made a mental note to inquire about this the next time I saw my D-nurse, and then forgot about it again - well at least until the next time I saw a crazy number that called for inspection of tubing and reservoir for air bubbles :-)
The cracks are visible as thin white lines on the above pictures, my apologies for the poor quality of these, but close-up detail coverage isn't a force of our camera ;-) The cracks actually go all the way into the reservoir window, which on more than one occasion has made me question whether the reservoir was damaged, even if it was bright new and I hadn't noticed anything when filling it up.
Last week, I had an appointment with my D-nurse and showed her the cracks (in Denmark, insulin pumps as well as the supplies are paid for by the hospital treating you, hence I had to ask whether they would want to just replace it or if I should contact the pump company rep about it). Turned out, the decision and way of replacement would depend on whether the warranty period had expired or not - neither of us could recall exactly when I had gotten the now cracked pump.
A call to the company rep revealed that my current pump was still under warranty and so the company would send an identical replacement model (if the warranty period had expired, the hospital would have provided me with the newer Paradigm Veo). So now I have a replacement pump to set up before I retire the old one by direct mail to the company :-)
