I find the piston screw a bit fiddly and time consuming compared to my and other pumps allso i use fiasp insulin from a 10ml vile not a cartridge i am sure you quickly get the hang of it but i am trying simplify my overall control of my diabetes as i get older but thank you for your reply .
When I was researching all the pumps, I read a lot about the screw too, and I was nervous because some people kept mentioning it, but in reality the ‘screw’ part of it is a bit of a misnomer as far as the pump user is concerned. It’s just like a little attachment that you put into the end of the reservoir. It’s a clever idea actually as I believe it’s what makes the pump so small and light (62g including a full reservoir of insulin and battery). It also seems to work better than the plungers of other pumps.
When I first had my DANA RS, I was taking a few minutes to change/fill the reservoir but this soon sped up when I realised it was much simpler than I’d presumed! All you do is set the ‘screw’ (takes a second or two), put it into the end of the reservoir (another couple of seconds, then draw up the insulin into the reservoir
from your vial (so your Fiasp vial would be ideal as would Humalog, Novorapid, porcine insulin - whatever).
I haven’t timed myself changing a reservoir but it takes no longer than my previous pump (an Animas Vibe). The DANA RS reservoir also holds a full 300 units even though the pump is very small.
Apart from that, the pump itself is very robust, comes with lots of accessories, and is now the most popular of all the insulin pumps on offer at my hospital. I always spend time here going on about how good it is, but that’s because it is
🙂 Also, I’m very dubious about some of the ‘anti’ comments online because they bear no resemblance to what I’ve found from using the DANA RS for almost 3 years.
Good luck with your choosing
🙂
