Insulin Pump Transition Musing

The four-year warranty on my Deltec Cozmo insulin pump is up this July, which means that in a couple of months my insurance will pay for a replacement pump. Those of you who use the Deltec Cozmo, or those of you who follow anything to do with insulin pump news, know that Smiths Medical stopped producing this particular brand of pump two years ago. Actually, the company is slowly transitioning out of the diabetes business — if it hasn’t already. While I imagine diabetes supplies production is a lucrative field, I also know Type 1s aren’t as numerous as Type 2s, and because Type 2s don’t often use insulin pumps, maybe there wasn’t enough market share for Smiths to remain in the black with pump production.


It’s dispiriting to be moving away from the Deltec pump. I’ve heard from several fellow pumpers that the features on the Cozmo are incredibly intuitive and comprehensive compared to other pumps on the market. Some of you have used the Cozmo and used other brands, and you talk about how you’d always go back to the Cozmo. While I’ve always wondered what it’d be like to step out on my Cozmo (it isn’t really as sexy as some of the others), I’ve grown accustomed to the familiarity and reliability of my insulin pump.

Yet the era of Eric’s green Cozmo, of its familiar buzzes and beeps, and of drawers and closet shelves full of Cozmo supplies, quickly draws to a close.

I have options, and I’ve explored most of them.

There’s the option of going back to injections. I mean, that’s always a possibility. Yet I’ve grown accustomed to the insulin pump as part of my life with diabetes. I no longer find it a burden to live with an insulin pump in tow. At least, I’ve become conditioned to no longer think of it as a burden. Most of the time. The same way that the diabetes itself — most of the time — isn’t a burden (it’s all in the way I try to approach my perception of living with the illness; I admit there are times when such thinking fails).

An insulin pump allows me to maintain tight control over my blood glucose levels and lets me eat when I want without worrying about going high or low due to the actions of long-acting insulin such as Lantus. It’s as close, I think, as I can get back to the semblance of a nondiabetic’s lifestyle, and for that I’m grateful.

Then there’s the status quo option, in which I could continue to use my Deltec Cozmo pump past the warranty date. I quickly decided against this, though, so I’ve not done much research about keeping the Cozmo. Quite simply: regardless of whether or not people do do this (yes, I wrote “do do”), I’m more comfortable with getting a new insulin pump, something that’s not four or five years old and hasn’t been dropped, jiggled, bumped, stressed, subjected to moisture and temperature fluctuations, and which hasn’t been in constant use for four years.

I’m more at ease with newer technology regulating my basals and boluses, more at ease with a product that is under warranty. Plus, my insurance is going to cover the cost of the new insulin pump, so why wouldn’t I get a new one?

I’ve chosen to get a new pump, and in the coming weeks as events unfold with doctors and insurance companies and medical equipment suppliers en route to my new pump, I’ll keep you posted on how it goes. I admit that I’m slightly apprehensive about the transition, and I’ll try to write about some of that, as well.

I’m not a person who’s resistant to change, but I am a person who’s been through diabetes routine changes before, and such changes, I know from experience, don’t always go smoothly. I’m hoping my fears are unwarranted.

    Wishing you well with your new pump. I am a certified pump trainer for three companies. My son has been wearing a Medtronic pump for about 15 years. While I really, really like the Medtronic my favorite is the Omnipod. I have tried to persuade him to at least try it but seems he doesn’t like change and I can understand that.

  • Natalie Sera

    My only advice would be to see if you can get a test run with the Medtronic, the Animas and if possible the Roche Spirit (which is an uncommon pump). If you’ve tried them out in real life, you will know which fits your needs the best.

    I’ve been on Medtronics for 12 years now, and I find them completely intuitive, once you learn their vocabulary, which may be different from the Cozmo and the Animas. But you can find out which suits YOU for yourself! 🙂

    I, too, had the Cozmo pump and loved it. My warranty expired 3 months after Smith Medical decided to stop production.

    I went to the Insulet Omnipod, and I am happy with it. My reasons:

    I had had a Medtronic Model 511 which caused me no end of trouble–three replacements in 4 years; Medtronic’s tech support was inadequate. I understand that things may have now changed, but it seemed that everything that could have gone wrong did go wrong. I will not go back.

    My physician refused to work with Animas. He had had a bad experience with them.

    I love the wireless/tubeless technology of the Omnipod. It lacks the CGMS capabilities that are integrated into the Medtronic pump, but I chose to get the Abbott Navigator, and I am satisfied with the combination–particularly the accuracy of the Navigator.

    I currently use a Medtronic 512, but I would never replace it with another Medtronic. I have had multiple breakdowns and their supplies are constantly being recalled. Just received a notice today that the skin prep wipes I order from them are being recalled because of e-coli contamination.
    Eric, please advise us with the pump you decide on. I know you would not be happy going back to injections.

    I’ve been Diabetic for well over 30 plus years. I’ve been fascinated by these pumps as long as they’ve been around. But, have never been comfortable by many of the questines I have that never get answered by any of the reps. or companies. ie How safe is the insulin in the summer heat, or winter freeze…? I work outside. Now I leave by machine and insulin inside when I’m working. When I work on a big flat roof the temps reach well over 100. In the winter the temps regularly reach 20 – 30 below zero. How do pumps handle these? How does the insulin stay safe? My pagers and cells take a beating. How safe are these pumps from being hit/dropped/scrapped abused? Right now I take 4-5 shots of humulog a day(as often as I eat small meals) and two shots of lantus. am/pm. It’s the multiple blood testing I would like to eliminate to tell you the truth! From everything I read this method is the best way , behind pump therapy, to control. I tell people “control it, or it will control you!!.” I guess my questions pertain mainly to how can a pump fit me so that I don’t feel like the pump is in control of my life? I am very possesive of my diabetes. It’s mine! I control it. And I don’t want to have someone/something else in charge of me. I’m sorry for rambling. In my entire life I’ve never know anyone my own age who has diabetes except a girl in college. Thats why I support a youth diabetes group where all the members are 2-16 years old. It helps them and their families see others in their own positions. And, all these kids wear pumps. Thanks for listening. Dennis 🙂
