670G Suggestions for Improvement

Sorry for such a late reply, I’m a new user and just found this.
You’re not alone dumping Automode, I went off of it 6 months ago and am more content with just “suspend on low.”

IMO Automode software is way, way too conservative–doesn’t give any of us enough control of target BGs, nor any customization ability.

I couldn’t agree more with the list(s) but Medronic will never listen. I am extremely insulin sensitive(15-17 units/day) and it never fails I get an alarm in the middle of the night just to say I’ve been a minimum deliver for 3 hours and need to enter a BG. Now that’s exactly what I want to do at 2:30 in the A.M. Seriously I have found my BG is actually better when I’m in Manual Mode, but my Endo seems to look at % spent in Auto Mode until I share with her my trouble.

Remove the battery and insulin bottle icons — useless and waste of screen space. I want a way to see exactly how many units are left, not tell me I have 25 units left and I need to replace immediately. The cost of insulin is very high - I need to use every last drop.

Here are some of my gripes…

  1. Must reenter BG every time the pump exits out of Automode (like an infusion set change) even though the current BG value from the CGM is being displayed.

  2. The displayed BG will change when you enter in THE SAME value being displayed in manual mode, to get back into Automode. Your BG value has nothing to do with which mode you are in!!!

  3. I cannot use the fast delivery mode. I get “Insulin Flow Blocked” errors. Their reservoir plunger force detection has some design fck-ups.

  4. Different carb ratios are needed for Manual Mode and Auto Mode to account for micro-bolusing being cut back after a large meal bolus in automode. Your carb ratios should not change depending on what mode your are in!!!

Those were the big complains (that were not already mentioned in this thread) that I have.

Minimed has been unresponsive to my repeated complaints about excess everything the software is used unfriendly. I believe after 20 yrs this will be my last minimed product. I miss bolus’ are bother by repeated bg requests.
Times out on max or min basel all the time. This is caused by inadequate range to correct. In my case it will recommend bolus when high that’s about 20% of what would work. Rep told me the extra screens are because we asked for additional safe guides to prevent accidental bolus’. Why not make it user selectable ?
Not allowed to comment. Also don’t you love when the pump is showing multi able arrows and demands bg to stay in auto mode. Put in current blood sugar ruin sensor.

I agree with what is being said. Sorry, but I just joined this group today.
I have been using the Medtronic sensor, now the MMT-7020A, and the accuracy really stinks. I rarely have a sensor where the accuracy is +_20%. Whenever I call Medtronic they respond as if I only started using the sensor last week. After 3 years of this frustration of lousy sensor accuracy , I called the FDA today and filed an official complaint. Probably won’t do much good, only time will tell.

I am thinking of using the DEXCOM sensor instead of Medtronic. Is there anyone who has used both sensors that can tell me if the DEXCOM is any more accurate than Medtronic?


(Jess) #27

Skitter,
What kind of glucose meter are you using? I had to switch and use the Bayer Contour meter to calibrate the sensors with. I had lousy performance when I used my cheap BG meter.


(Robert) #28

I am also using the Contour next EZ from Bayer. It seems to do a good job. You should be checking the calibration at least twice/year.


(Robert) #29

Why would the disposable sensors be any better than what is offered now for the 670G (Guardian 3) ?


(Sal) #30

It’s still a while out, possibly another year or two, but the advantage of having a single device is that:

  1. You won’t have to wait for your transmitter to charge in between sensor changes.
  2. Having the sensor and transmitter in one device will make it more reliable. As with all technology, the less parts involved, the better.

Other benefits include are that it’s expected to last 10-14 days between changes and it won’t require calibrations. If the FDA approves that, it essentially would be that it’s reliable enough to not require it.

CGM technology is still in its infancy.
