Hi Lathump. I'm thinking that if you plan to use your old pump as a backup, it would be prudent to put in a new battery once a month to keep it ready to go as well as keeping a print-out of the settings. The print-out you mentioned will come in handy to program your new pump.
Lathump, It took Medtronic at least two years to realize that Melissa's pump was out of warranty. When they called me I just laughed. As if I would have her using a pump that was 6 years old! We kept her pump for at least 3 years, and it was still working when I gave it to Michael to take apart. I knew that she would never use it because we had 2 Omnipod PDMs and the Cozmo for backup. I never kept a battery in it and it worked just fine the couple of times that we had to use it during the first year or so on the Cozmo. I think it would probably last longer without running.
I'd be interested in Medtronic's answer. I'm not using my pump right now, not sure that I ever will again, but just maybe... So I put in a new battery on the first of every month. Let us know!
I replaced my pump recently but they offered like $500 price to keep my old one so I gave it to them. Part of me wanted a pump but, given how smoothly the replacement process had worked, I figured I was ok to give it up.
AR-If I had been paying a deductible, Animas would have given me whatever the going rate is against my deductible ($500 I assume). However, my insurance is covering my pump at 100%. This is the first time that I have ever kept an old pump. Always traded them in before. My guess is that I will never use it again, but you never know.
MaryMary-I'm with you that I will just take batteries and reservoir out.
Lathump, I think your assumption is correct. I've done that myself...saved my old pump, taken out the reservoir and battery, and store it in a box. When I want to use it (i.e., going on vacation and wanting a back-up with me), I just insert a battery and program the pump, and it's ready to go.
My spare pump is in the box that my new one came out of, I rewound it, removed the battery and placed the red plug back in the reservoir port. Note: Medtronic pumps store user data in Volatile memory so some of your data will be lost after a extended amount of time without power. I also placed a printout of my old pump settings in the box just in case the Zombie's have destroyed my ability to access the internet and retrieve my current settings from CareLink...
If you try to keep your spare pump running it will just wear out the motor over time, and other parts. The stepper motor is always powered up, the battery power is holding the motor in it's current position with a electromagnetic brake.
