Is this right - that even though the handset/meter has calculated it and told the pump - you STILL have to fish the pump out from wherever to say YES! ?
No, sorry Sedge... I have confused you!!
On the MM640G you have two options (well... two and a half, but first things first).Option 1 - Standard bolus wizard option on pump
Test BG with paired NextLink meter*. BG is automatically transmitted to pump which offers a 'Do you want to bolus' screen. By the time you've put the meter back on the table and unclipped the pump it's ready. Add carbs, press OK choose if you want standard or dual/square (if enabled) and Bob's your uncle.
* You don't have to use the Contour meter. You can manually input BG values from any other meter, inc Libre if you want to, on the first screen of the bolus wizard. This is particularly useful if wanting to use a calculated/iob aware correction from Libre (or if you simply prefer another meter).Option 2 - Direct bolus from meter (no wizard)
If your pump is buried within clothing and you don't want to fish it out - eg fancy frock event - you can test BG, guess carbs, work out approx dose in your head, then choose 'Bolus' on the meter and deliver a straight bolus of whatever units you want.Option 2a - Fancy bolus from meter (no wizard)
The direct bolus (variable units) is all delivered in one go. If you want a dual/square style fancy bolus you have the option of setting up to 5 presets in the pump than can be selected and delivered from the meter without fishing the pump itself out from within clothing. Presets include the amount of insulin as well as the distribution and length of the fancy bolus. Sadly for me this makes them rather less useful. I'd prefer it if I could set up a 60:40 2 hour pattern and then choose the number of units at the time, but the way the system works for fancy boluses is you have to know it's 6u (or whatever).
As a result if I were ever spending a day in a suit of armour etc and needed to use the BG meter to bolus I'd probably just use a sequence of simple boluses rather than faff about with DW/SW. After all, for those kind of events I'm usually making wild guesses about food/doses anyway so the precision of the wizard becomes less important.
I can see that if you regularly wear the pump somewhere inaccessible then these probably aren't enough, but I'm more than happy to have them as options as Threepio is always hanging on my belt and easy to get to.
Hope that explains it a little better?
