Hey!I've had the Medtronic 640g for 18 months now, this is my first pump so I have no direct comparison for you unfortunately.
The menus are overwhelming at first, but like anything really, when you are using it day in day out it becomes second nature. you can give such tiny increments of insulin if you really want to fine tune your BG's, ranging from 0.025 to 0.1 unit. It is slightly 'chunky' but I think that is to house a large reservoir of insulin (around 300 units) which is why I chose mine, due to my large(ish) appetite. Though the pump requires a lot of work from you, I'm sure whatever pump you go for, you will realise, it's a definite game changer. It's also helped reduce my HbA1c to 6.4%.
It depends how much insulin you use. I change mine every 5 or so days.Hey!
I'm thinking about changing my current pump to 640G but I was wondering if it's too tiring to keep changing the hole reservoir every three days - is it? I mean, I travel a lot so I wonder if it gives too much trouble.
I have a Vibe, not 640G, but change my cartridge every other day.Hey!
I'm thinking about changing my current pump to 640G but I was wondering if it's too tiring to keep changing the hole reservoir every three days - is it? I mean, I travel a lot so I wonder if it gives too much trouble.
Oh good, that's comfortingIt depends how much insulin you use. I change mine every 5 or so days.
On that basis, you'd get about 10 days out of the three ml reservoirs in the 640G!Oh good, that's comforting
I use about 1,8mL for 6 days approximately.
That's great!On that basis, you'd get about 10 days out of the three ml reservoirs in the 640G!
Hmmm I see. I think I'm gonna call Medtronic and ask them it give it a try with the 640G before doing anything so I can check this kind of thingsI have a Vibe, not 640G, but change my cartridge every other day.
It would last 3 to 4 days but the cannula gets irritating after 2 days so I have to change that and it is easier to align the cartridge change at the same time.
It takes less than 5 minutes in total which is less time than all the injections I used to take on MDI.
I know there are pumps with larger cartridges available (Vibe is 200 units) but I favour something small than adding more bulk to the, already bulky, pump.
There are also pumps with pre-filled cartridges. However, I would feel there is a lot of wasted insulin because you only have a full cartridge: I can put as much insulin as I want in my cartridge and not throw as much away. I actually syphon the remaining insulin out of the last cartridge and put it in the new one to minimise waste.
I normally use lithium batteries that I get from Sainsbury's as I feel bad getting the NHS to pay the elevated prices that pump companies charge for normal alkaline batteries. With those, I usually get around 4 weeks in a 640G.That's great!
What about batteries? Do you use a specific super powered one or the a normal one? How long does it usually lasts?
Ok, thats good! When o called Medtronic to explain to me how the pump works they told my that the batteries last 4-5 days only, and that sucks.I normally use lithium batteries that I get from Sainsbury's as I feel bad getting the NHS to pay the elevated prices that pump companies charge for normal alkaline batteries.

Hi, sorry for the late reply, I do a complete set change; cannula and reservoir every three days without fail, I tend to only fill my reservoir to around 200 units and I pretty much use all of that, with a small amount of contingency. But I cant see why you couldn't fill it and replace when empty, just as long as your change your cannula when required. Do you change your cannula every three days?Hey!
