The above Photo was taken on the day I received my T:Slim Insulin pump. I got this Insulin pump back in November, on the day before Thanksgiving. So now, for me, “T-Day” also stands for “T:Slim Day”.
After these past few months, I am still nuts over this bit of diabetes technology. I Love its’ ease of use with the high-contrast touch screen, and 10-key number pad for entering my blood glucose and carbohydrates, adjusting basal and anything else I may need to, makes it so much easier than the old days for ‘scrolling’ with an up or down arrow button.
Today, on Twitter, someone asked me for a little run-down of what I like and what I hate about the T:Slim. Well, it’s like this: I don’t “Hate” anything about it!! I think this is the best bit of Diabetes tech I’ve owned. “Hate” is a pretty strong word.
I prefer to say I have an “I would LIKE” List. Things I’d LIKE to see added, but it is not a deal breaker if they’re not added right now. Indeed, the Tandem Diabetes Care company is new, they have ventured into the piranha-infested waters of the Medical device industry. In my opinion, the only way to go is UP!
My “I would LIKE” list is as follows:
** I would LIKE to see a slightly longer “pigtail” from the cartridge, It should be longer by about 2″ to allow us to tuck the ‘luer lock’ into our clothing… Me? Into my waistband or underwear.
** I would LIKE the T:Slim to be integrated with the Dexcom CGMS (Continuous Glucose Monitoring System). If and when they do, I would hope my CGMS data would upload through Tandem’s T:Connect software on my iMac. At this time, Dexcom is a stand-alone CGMS, a very nice system, but it does not work with Mac OS!
Considering the CEO of Dexcom, Terry Gregg, in an interview on TuDiabetes (YouTube Link here) is a self admitted “Apple-Guy”, I find this to be …. anomalous. As I understand it, Both Dexcom and Tandem are doing trials of this now for the ‘Artificial Pancreas’ so… y’know, why not? The T:Connect is wonderful for me, and it also uploads from my OneTouch Verio_IQ meter. Both of these devices go into my main report in T:Connect.
** I would LIKE for the top membrane where one fills the insulin cartridge through, to be better marked on where to pierce the filling syringe into. I have noticed that I have to try two to four times before I can actually fill the cartridge. If I have not gone to the correct area, the Filling syringe plunger will NOT budge. So, I pull it out and try in another part f the little membrane.
Ironically, the ONE morning I had to do an emergency fill (I’d let the thing run completely out) before work, and Before COFFEE no less, it all went FLAWLESSLY!!
** I have had no complaints but I have read several other posts in our FaceBook group for T:Slim users that the case/belt clip combo that ships with the pump is “Too bulky”, “Too fragile” and that people would like a closer clip for the T:Slim. Tandem sent us all a T:Clip case around Christmastime, which is nice, a bit thinner, comes in colours, but the clip doesn’t rotate.
I have pointed out on more than one occasion in our group that Tandem doesn’t make the cases. They have partnered with a company called Myabetic, who is known for dressy, quality cases and carrying solutions for the discerning PWD to carry their daily needs. Not just the T:Slim, but meter cases, cases for ones’ insulin and syringes, or pens, what have you… I suggested perhaps, that people should contact Myabetic with their wishes pertaining to this accessory. I use the T:Holster. This is a nice, slim pouch, with a rotatable belt clip and small magnetic tab at the top. This is a fine solution for me.
Yet, we all have different tastes and wishes. *I* would love to show this pump off. I’m not at all embarrassed to have diabetes and I really don’t see the point in trying to hide this part of me. I’m soon to try a rig-up of a Minimed belt clip on my T:Slim. Let its’ “Beauty” be seen! One poster in the Facebook group is actually using the Medtronic Minimed clip for their 5xx insulin pump series on her T:Slim and is comfortable with it. I ordered one from MM as well and will also try this.
I love the beeps, reminding me to change a site, Do a glucose test, Low insulin, whatever. I can hear them very well, and I need that sometimes.
I love the offset way the T:Slim delivers insulin. Instead of a Straight out, down the infusion line into your site, it’s brought up from the main cartridge into a smaller reservoir and sent out from this. Tandems’ Advanced Micro-Infusion is pretty darn nice!
This is, in my own opinion, a beautiful insulin pump. I got very tired of things we have to use as looking too “Medical”. Too utilitarian. If we HAVE to have this condition, I think we should have to use decent devices that can look nice.
I know that – for some folks, it hasn’t been tested to use with an insulin called Apidra, I know of one who had to give up the T:Slim because it did not play well with her Apidra. I use Humalog, others use Novolog and those seem to work quite well with the T:Slim. From our group, I understand that if you change the cartridge and set every 2-3 days even Apidra might be fine in the T:Slim. One must only be aware that this has not been tested with the T:Slim.
I’m very happy I went through the insurance hoops and appeals and got this insulin pump. If a medical device can ever be called “Beautiful’ in appearance and ease of use, this would be one of them. After all, I still call it “My Baby T:Slim” Even though there is NOTHING “Baby” about it in performance!
********UPDATE On Clips/Cases*******
I did a little experiment with a MM belt clip. Got the one for the 523 Paradigm series, and WAS going to gift it to a pal today. She already got one (!!) So I brought this one back, I tried my T:Slim in it.
It works very well, but the pump could slide out from the side(s)…. So my Brain kicked in and I applied dots of Jeweler’s glue to the inside of the clip. I let this dry.
So, now it stays put. You can see the ‘dots’ of the dried glue, bracing the pump into the clip, but it is easy to remove when I want to.
My T:Slim is in the clip and the dots I put in are ‘tacky’ enough that it will not slide out. Now I can rock my T:Slim as the “STAR”. So pleased & I thanked our groups’ poster who had this idea!
