Pump Choice for DIY Closed Loop with Libre

[Colin of Kent]

I'm not sure if I'm just not looking in the right way or the right places, but I can't find the answer to my current conundrum, so I'm hoping some of you might be able to help, please.

I currently use a Libre 1 + Blucon Nightrider + xDrip+ to make a CGM system, and I've also been using a pump for 14 years or so. I'm now being offered a choice of four new pumps to replace my current one which has come to the end of its warranty period. I'm thinking I'd like to turn the setup into a closed-loop system if possible, so I need to know if any of the pumps on offer are compatible with my CGM setup.

The pumps available are:

• YpsoPump
• Tandem T-Slim
• Medtronic 780G
• Medtronic 640G (see below)
  
• Medtrum TouchCare Nano

Can I get xDrip+ to talk to any of these? If so, how?

Thanks in advance!

Edit to add: I've just been told by Medtronic that I can continue to use my current 640G. They supplied it to me only a few months ago, just inside the warranty period. It seems daft to me to dispose of such advanced tech in an age when we all have to consume less. So I asked the question.

I don’t know about other pumps but xDrip does NOT talk to the Medtrum.

I doubt that xDrip+ will talk to any pump.
I believe that Tandem are looking at linking the T-Slim to the Libre 3 when available.
Have a look at: https://openaps.readthedocs.io/en/latest/

Come and have a look at android aaps on Facebook or twitter. None of those pumps will close loop but it might be worth having a conversation and pushing for a Dana pump which will close the loop with xdrip.

Good luck!

I have read somewhere that the tandem will likely work with the new libre3 in the future. But will be quite a while before uk gets it

I guess that Freestyle Libre3 will be available in UK (hopefully next year, dependent NHS). This will be another full CGM available for closed loop solution. Abott is actively working/testing on closed loop solution with many accessible pumps, especially with Tandem and Omnipod.I guess that OMNIPOD will introduce a new pod OMNIPOD Horizon (hopefully also next year in UK, dependent NHS). I guess in the following 12-24 month we will see many more closed loop solutions upcoming. Also dependent on the NHS.

It's a shame I'm not allowed to post links, yet, but if you search for "AAPS readthedocs" that will get you to the online manual for setting up an Android Artificial Pancreas System. On the left, under "Getting Start" is a link to "Compatible pumps" which list all the currently viable pump choices.

I know from experience that Medtronic are very closed to interoperability, as in they actively try to prevent their system being integrated with any others. So although some older models have been cracked to enable them to loop, your existing 640G won't let you. I think the Medtronic 780G can do it's own closed loop but only with the Medtronic CGM system.

As others have said, I'd petition your diabetes team to make available one of the ones on the AAPS compatible pumps list, if I were you. That's what I did when my 640G went out of warranty, and I moved over to a Dana RS, then more recently a Dana i. I've been happily looping with AAPS, ever since.
