Designing Diabetes Gear?

Joe asks: "I'm a grad student studying medical product design. My thesis work is being done on devices used in the monitoring and treatment of Diabetes. I'd like to solicit feedback from the Slashdot community regarding the state of the art in the field. Are you a Type One who loves the OneTouch UltraSmart, or a Type Two that swears by the multi-strip AccuCheck Compact? My goal is to develop products that meet the varied needs of diabetics, in a manner closer to the iPod, rather than the current products which resemble crappy 2-button Tiger electronics videogames. What features in these devices do you like and dislike?"

I'm a type 1 diabetic, using a disetronic d-tron pump and a disetronic freestyle blood tester.

One thing I've noticed is that though I test regularly, I only create overviews of test results every now and then. Those overview are important to gain insight in how well I'm regulated, though, so I should do that more often.

Now the blood-test device has a serial cable link to my computer (linked to windows-only software, unfortunately), so I can load all the past results on my laptop (the only machine in the house that has windows installed), and create a few nice looking graphs.

The D-Tron pump actually has an infra-red port, but for some reason no software has been released to actually make use of that. This is a shame, since my glucose-level graphs would gain a lot from the extra data of my pump's insulin extrusion.

Then there's the additional data that can be very useful when reviewing blood glucose levels, such as 'right after a hypo', or 'ate too much ice-cream', or '1hr prolonged bolus to compensate for pasta', and such. The only way to store that, a the moment, is good old fashioned paper. Which means that I often don't...

So for me a good device would:

• Allow me to store either free text, or some pre-defined tag, along with the glucose-level values. (or voice tags?)
• Allow for ease transfer of data to the PC (and preferably not just in a windows-only proprietary interface. I want to be able to load stuff into a spreadsheet and such...)
• Allow me to read my pump data, though that is a software issue, not for the device you'll be working on

Other things that are appreciated are: small size, inclusion of the finger-pricking thingy in the same package, being able to load a set of control-strips, backlight for checking in the dark, NO SOUND option (my wife is sleeping next to me, and I don't want to wake her just because I want to check my blood sugar).

The freestyle also allows one to check from blood on the arm, instead of the finger. This is significantly less painfull, so encourages checking. It also lags a bit; The values from the finger will be more up-to-date than those from the arm, so it's not good for when you feel a hypo coming up. Still, a good feature.

Simple is better

A few years ago I worked on a team that developed a complex blood glucose device, sort of like the one you described yourself interested in developing but the market just wouldn't bear it, so it was canceled. The only thing the market will tolerate is nearly cost free and designed so the criminally stupid can use it. Forget graphs, forget statistics, forget all of it. If you can figure out how to do it without any buttons so much the better, it's a shame we can't eliminate the user entirely. Do keep data storage and data transfer, because if there is a larger group of (walking free) self delusional pathological liars than diabetics, I'm not aware of it. It's not that I hate diabetics I just hate the devil inside them. (If my sister is reading this she knows I am talking about her too!)

And I suppose since you're interested in doing this to begin with you already know that there are some very big and very predatory players in that market who tolerate competition less than Microsoft and are significantly less friendly. Still it's a great technology to get started with, it's very easy implement and there is a large market.

Fair disclosure: I work for one of those big companies who may either sue you out of existence or buy you so the world can forget about you.

Type I - Use the Accu-Check, when I use it...

I'd agree with the above poster who said Diabetics are mostly pathological liars, we are. Believe it or not, testing your blood sugar SUCKS. It hurts, I don't care if it's your finger or your arm. (By the way, 20 minutes ago isn't good enough for Humalog insulin, so arm testing is risky at best.) If you have a tester with an IR port, there IS software that will read and input the data, but you might need an M.D. to get it. My doctor has some really nice software for the Accu-Check, but as a "user" I'm only able to get a really really dumbed down version of it for 50 bucks from the manufacturer. >:( I don't like implants, which is why I don't pump. But if you can give me a way to test my sugar that doesn't hurt all the friggin' time, I'd use it. I like feeling good as much as the next guy, but being in pain my entire life just isn't worth it, to me. That's what I care about. With the technology and resources available today, there has got to be some way to remove the pain from treating this damn disease. At least until we can convince the Bible belt to allow continued research in stem-cell technology... But I think we'll have to destroy a lot of drug and equipment manufacturer's before that'll ever come about. :(
