Roche have a program the clinics use, to set a 'starter' basal rate and presumably your clinic has already given you a list of 'new' things you need to get on your 'repeat prescription' list so you already have it, to start you off - whilst other pump insulin reservoirs can be filled either from a vial or - with some difficulty LOL - from a pen cartridge, the Insight pump MUST have the little 1.4ml 'Pump Carts' or nothing. You also need Accu-Chek Aviva test strips - these are common to most types of Accu-Chek meters so it's easier to have another Roche meter as a back-up spare. I previously used their Combo pump meter/handset - which is the same basic thing as the Accu-Chek Expert meter, but with added Bluetooth to communicate with the pump.
Like I say - lots of things will make much more sense, once you actually get your hands on the thing!
If something doesn't make sense - ASK!!
The Roche pump helpline really ARE helpful, too. You are never really 'up a gumtree without a paddle', LOL
