Recent issues with my T-Slim

I've had my pump for a year now, and the past couple of months I've noticed that once I get down to about 40-50 units remaining, my pump starts having some issues... It will give me at least a couple of occlusion alerts every time that I bolus, and…Continue

Infusion set bent cannula

So I spent 7 hours in ER today. Mild DKA. Changed my infusion first thing this morning and 2 hours later BG was almost 400. Changed the set again and notice the first set had a 90 degree bend at the end, so I thought that was the problem. My BG…Continue

How low has your battery % gone?

When I was trained on my t:slim it was recommended that I charge the battery a little every day. But I found that not to be too practical for me. So now I just let the battery drain and then give it a full charge. The lowest battery % i've gone down…Continue

Hi Guys,I have been using my T-slim since around October. It is my first pump. I have noticed something recently that I can't figure out. When I fill my cartridge, I have noticed that some of the insulin goes "missing". For example, if I draw up 260…Continue

We have my 3 year old doing a clinical trial on this device,Which requires me to check his BS at midnight & 3AM. On the second night while i was inputting his BS at midnight the tubing came apart, I quickly put it back together and went to bed, Well needless to say when i woke up at 3AM to check his BS i went into a panic when it was almost 500 due to what seemed to be little air pockets in the tube. Does this happen often? I know we are new to this meter and still on trial for someone so little but that honestly scared me to the point where i told my husband to rip it take it off.

I hope this does not happen often because my little guy will not be happy to have shots again

I have had my sites "go bad" several times and have changed the infusion set and not the cartridge. Just go to the load, fill the new set and you are good to go again (hopefully). Each of the load steps can be run independently and they do not have to all be run each time. Since I use Inset sets, I change the tubing and the site as it is an inserter based set. I just refill the tubing and site and re-insert.

Comment by 2hobbit1 on September 13, 2014 at 1:19pm

Site can be changed independently from cartridge and tubing. If you go to load, you have option to select each of the steps independently. Just disconnect from your site. Place a new one and then reconnect. Then all you do is prime cannula.
Personally I always run a 200% basal rate for 15 minutes after a site change. Seems to help with absorption.

Comment by duckatect on September 13, 2014 at 8:50am
Changed my infusion site yesterday but I suspect I chose a bad site. Question is; can I prime a new set without changing the cartridge?

Hello everyone! I'm new to this group. I am 43 years old. Type 2 mis-diagnosis by GP in March. Official Type 1 diagnosis on April Fools Day by my Endo. No Joke! The past few months, I have been reading voraciously and learning all about what I need to do do manage my broken pancreas. Since diagnosis, I have gotten a Dexcom and changed to a low carb diet. I'm fully insulin dependent. No honeymoon period, c-peptide is zero...My A1c was 12.2, but as of last week it's now 5.8. Woot!! Just got approved for the T:Slim this morning. Can't wait til it gets here!

I received a loaner once from Animas, around 2006. There was no cost, and shipping was quick. I read the terms, which basically say you just need to send the loaner back when you are done, otherwise they will bill you the full purchase price.

I would never do it again though. I'm more concerned that the pump I'm not attached to could get stolen, and I'd be out thousands of dollars (or at least my renters insurance deductible). I have never had a malfunction with my Tandem, so when I travel internationally again, I'll just bring a handful of syringes.

Comment by kirin on August 19, 2014 at 1:59pm

We are going to Maine for two weeks where we will stay on a lake in a small town 20 miles inland from Rockland. I will be sort of off the grid on this and well away from my endo, in a place where they may not have ever seen a T:Slim pump and where the mail and express delivery is sketchy at best. I called Tandem and explained what I was doing and they sent a "vacation loaner" T:Slim by 2nd day air to my home. It arrived as promised in a sealed box with UPS return postage already affixed to the return shipping label! All I have to do is call them if my own pump has a problem and work through trouble shooting with their tech support. If that fails, they instruct me to break the seals and use the box to return my broken pump to them. Otherwise, I just return the loaner when I return.

There was no charge for the use of the loaner or the postage. They did not even ask for my credit card! All I had to do was sign a "loaner agreement" before they shipped it. The agreement was two pages long and outlined the instructions and my responsibility and was not overly "lawyered-up".

My understanding is that Medtronic charges for loaners each time you need one. I do not know about Anamas.

This gives me a lot more confidence to go off the grid into places I had no problem going when I was on MDI. While I am taking syringes and insulin with me, the spare pump is a lot easier than "back-converting" to MDI if my own pump fails.

Tandem has shown to be very customer oriented as compared to the nonsense I got from Medtronic when I was evaluating the various pumps!

In another vein, my endo wants me to change sites in less than 3 days. This requires more Inset units. Since my prescription renewal is 8/28 and we are leaving on 8/23 (shipping is not an option where we are going as it is spotty and questionable is at all) I could not get the additional sets until the renewal on the 8/28 renewal, leaving me on the old 3 day switch out. Medicare will not allow early shipments unless you are going out of the USA and you have to give them a travel itinerary. Great, stay in the USA and they will NOT ship early!

CCS medical (my T:Slim supplies supplier) was GREAT! They understood the problem and did not bury me in the Medicare rules. Instead, they sent me the additional sets of Inset infusion and T:Slim reservoirs to allow me to switch to a two-day cycle before I left for Maine until my new prescription for the increased supplies ships on 8/28.

Another company that knows the meaning of customer service!

Every day and with every contact with Tandem and CCS my decision to go with Tandem is reaffirmed!

Andy is right, you will get used to the time it takes to prime. It can be annoying at first, but once you learn the routine you can find ways to streamline the procedure.

As for the remote, I never had one so I can't say. I can say that entering date into the t:slim is easy peazey.

Comment by Andy on July 28, 2014 at 9:09pm

1. You get used to the (lack of) speed.

2. I've never missed having a remote when I'm physically attached to it anyway. Think of it this way: you now get the opportunity to ditch a large meter and use something tiny like the Freestlye Flash Lite.
