Is Tslim Worth the Trouble?

I’ve been using a Minimed 722 for the past 4 years. A few months ago, my out of warranty 722 started giving motor errors followed by button errors after a brief swim. Minimed has a “Continuation of Therpy” program where they will lend a pump to out of warranty customers for 90 days, so I went ahead and traded my dead 722 for a loaner.

I wasn’t ready to settle with Minimed for another 4 years, especially since I prefer the Dexcom G4 as a CGMS so when my loaner pump had to be returned, I decided to give Tandem’s TSlim a try. This pump clearly has it’s own advantages and disadvantages but the main selling points for me were the size and Tandem’s partnership with Dexcom.

I’m now pumping with TSlim, but am not sure if I want to keep it.

Some of my main observations about this pump:

  • Color Touchscreen:¬†Yes it looks great and makes the pump look more like something you’d see in 2014. Unfortunately, the main added benefit is that there is no scrolling required to enter blood glucose readings, carbs or insulin boluses. Since I do almost all of my bolus calculations mentally, this does not add a lot of value. It will, however, be interesting to see how they will incorporate Dexcom sensor values into the touchscreen interface in the future.
  • New Cartridge Technology:Tandem’s new cartridge supposedly offers extra protection against pump malfunctions by separating the line of insulin from the cartridge/reservoir with the added bonus of being more compact. It sounds great in theory, but bubbles are near impossible to remove from this thing. I posted a review here a few years ago about FiftyFifty’s luer lock Minimed cartridges which similarly were very difficult to remove bubbles from. Read More »

Mixed thoughts about Quicksets

I’ve been using Quicksets for a few weeks and gone from hating them to loving them multiple times. As I mentioned in a previous post, I used to use Insets with my Animas pump. Well, unfortunately, I can’t use those anymore because of Minimed’s proprietary connector but as far as reliability and ease of use go, they were great.

A couple issues I have with the Quickset having come from the all-mighty Insets.

Quickserter

Insertion – The Quickserter is not quite the tool it seems when watching video demos on Minimed’s website. It took me up to 5 minutes each site change just to get the thing loaded properly. Nothing like the Insets which come attached to a nice disposable plastic insertion device. My frustration with the Quickserter grew so I decided to try inserting a Quickset manually. The first time was slightly nerve racking Read More »

Dexcom Seven Plus vs. Guardian RT

Continuous glucose monitoring is becoming better and better, but still isn’t without flaws. Here I’ll compare 2 systems currently on the market–the Dexcom Seven Plus and the Guardian RT.

Sensor Insertion
The Minimed’s insertion is simpler and and more straight forward, but I like the Dexcom insertion better. First of all, the way the Dexcom’s inserter is designed, it is much more difficult to mess up with the angle and the insertion needle is more likely to enter the skin fully. With the Guardian, if I was at all hesitant when pressing the trigger, it wasn’t uncommon for the insertion needle to only make it half way in. Overall, the Dexcom may be a little less painful, but they are quite similar in that respect. It is much more difficult to remove the insertion device and connect the transmitter on the Dexcom, so this may make it less favorable for those wanting to place the sensor in harder to reach areas.

Transmitter/Sensor design
As far as the design of the transmitter and sensor go, both systems have advantages and disadvantages. The Dexcom adhesive patch is much better than the Guardian. So far, it has been totally unnecessary to use any type of dressing that was necessary to make the Guardian transmitter/sensor stay on. The Dexcom’s adhesive patch is larger overall, but worth the size in my opinion given that it is much more secure. Plus, once you put Tegaderm or IV3000 over the Guardian’s sensor, it’s going to cover a larger area. Read More »

Fifty50/Applied Diabetes Research insulin reservoirs are a disappointment

Recently, I switched from an Animas pump to the Minimed 720. Having been completely happy with Insets, I was hesitant to switch to anything else. I stumbled upon these Fifty50 reservoirs for Minimed Paradigm paradigm pump and naturally they caught my attention. Hoping the luer lock reservoirs would make for a smoother transition, I purchased some at the same time I ordered the new pump.

It’s a great concept, but the reservoirs leave much to be desired as far as removing air bubbles. I never had problems with air bubbles when using my Animas pump, so I had no idea what I was in for. Read More »

Entering the diabetes blogging world

It seems everyone with diabetes these days has their own blog. Here it is. I have finally given in and jumped on the bandwagon. Why? Because living with diabetes for 7 years and having an obsession with near perfect control have led me to believe that perhaps I have some information that could be useful to others. That’s all for now. Hope to start posting soon.
