Designing Diabetes Gear? 101

Posted by Cliff from the blood-sugar-determination-should-not-be-a-pain dept.
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?"

    My father has adult onset and uses the One Touch. His degraded vision was one of the major problems he developed as a result. I know he has trouble seeing the LCD. Another problem is the loading of the tiny strips. I imagine the multi strip would be better for him, but he resists change and having to pay for it.

    If you are going for the cool stuff, a reader that store the results, timestamps them and can display graphs of the sugar levels would be a great tool for doctors. You can bring in the unit to the doctor and he/she can get all the information they need. Adding wireless or USB/Firewire connectivity would let the doctor download the data file directly.

    • The Accu-Chek Complete [accu-chek.com] from Roche Diagnostics has most of the features you ask for, with the exception of wireless and/or USB/Firewire.

      It does feature a 19,200 baud serial port, so it's faster than most wired meters (most are 9600 baud). It is their geek's choice of meters.

      Most doctor's offices already have the software and cables necessary to download and review their patient's data. Similar software and cables are available (and included with Complete) for consumers to use at home.

    A tattoo on your arm that responds chromatically to insulin, sugar, etc. etc. levels in the blood and that could be read by something like a barcode reader would be good. Doesn't even have to be visible to humans, just the machines.

    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.

      Type 1 here, no pump.

      I've used three meters in my life:

      The One Touch II (a classic, and for a long time THE meter used by diabetics.) Big, clunky, single-strip design.

      Glucometer Dex (There is a Dex II now, I can't see what the difference is.)

      Accu-Check Compact

      I would never use the One Touch again - Lifescan still has no cartridge-based meters, and being able to load the meter with multiple strips is REALLY nice.

      The Glucometer was a damn nice meter. 10 strips per cartridge (they were the first company to release a cartridge-based meter), you could order the interface cable for free and their software (WinGlucofacts) was pretty nice, and it was free (free as in beer, that is) too.

      The Accu-Chek Compact is also really nice.
      Pros: IR data transfer
      17 strips per cartridge
      Formulary with my insurance company. That's $30 per strip refill. (You'll see a common theme that the insurance company dictates what type of insulin/meter you use to some degree. Although I'm using a Novo Nordisk insulin pen with Novo cartridges because there are no pens for Lilly insulins that dispense half-unit increments anymore.)
      AA batteries - the button cells in the Dex were annoying.
      Form factor and carrying case make it great to put in a jacket pocket for a night out.
      Adjustable puncture depth lancet device. (The other meters had this too but you had to change tips to do so.)

      Cons:
      Battery holder is loose. I often find myself having to push the batteries back in. Meter loses its time frequently because of this and has to reset the drum. The "find next unused drum slot" feature is nice in cases where you accidentally take the batteries out for too long or accidentally hit the cartridge chamber release.
      Cartridge chamber is too easy to unlatch, and comes unlatched often just by removing the meter from its case.
      No open protocol documentation, software is $30 and may be rigged to only work with their external serial-to-IR adapter instead of a normal serial IRDA port (they do not mention IRDA ports at all, they ALWAYS try to sell their $30 adapter even though I know the meter can speak to a normal IRDA port.) There are protocol dumps linked to from the Zaurus User Group forums, I think the "off-topic" section. I wrote a Perl script from those dumps, it's posted to those forums.
      Form factor of the meter/case is good for a night on the town but not as good for extended trips. The Dex case had lots of extra pockets for pen needles, extra lancets, etc. and was very flat. The Compact case has no extra pockets, just an elastic band to hold a spare test strip drum and one to hold the lancet device.
      Lancet device is not compatible with half the lancets on the market, including my personal favorite, the B-D Ultra Fine. Most lancet devices have a round holder that can also hold "flat" lancets via a friction fit. The Accu-Chek lancet device can only hold "flat" type lancets, not round ones like the B-Ds.

      The Compact also allows "alternative site" testing (i.e. not the finger) but has so many restrictions on when you can do it (see parent posts' mention of lag in the reading) that I never bother.

      Don't try to go too fancy. People say they will want it, but so far every attempt at a meter that "does everything" (onboard statistics/data collection) has bombed. Non-invasive testing is a VERY desirable feature, but so far no one has succeeded in making an accurate NI meter that wasn't more trouble than it was worth. (The Glucowatch was expensive, known for causing skin irritation, and not very accurate. Due to the skin irritation, people preferred the occasional pinprick, which with a good lancet and properly adjusted lancet device depth, you barely feel.)

      My advice: Try and convince Lilly and Novo Nordisk to bring back their 1.5 mL pen cartridges. Pens for 3 mL carts such as my new NovoPen Junior are fucking huge. :(

    This is the one I use. Frankly who cares about style? The main thing is cost. I am lucky and my insurance pays for most of my cost of strips but I know some people that even with insurance have a hard time making ends meet. It needs to be acurite, reliable, and cheap. The cheaper it is the more people can afford to test and the better control they will have over their blood sugar. Reliable means they can use the same meter for a long period of time. I so do not care about what it looks like. A back light on the screen might be nice for those with failing vision. Open specs on the dumping system so open source can make FREE tracking software to help keep the cost down as well.
    BTW I would recommend that most slashdoters get there blood sugar checked at least once a year. Some of the risk factors are over weight, are not very active, have a waist size greater then 38", eat crap, and being a member of one of these racial groups , Native American, Hispanic, Asian, or African American.
    I was over weight, and Native American and even though I was right at 38" I won the lotto and got it. Another big risk factor is if it runs in your family the problem is that it might run in your family and you might never know it. It is a sneaky thing.

    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.

    The UltraSmart is pretty good. Nice, highly readable. The backlight only comes on when you hold the button, so it saves on battery time. Those are all good things.

    Annoyances: Although it remembers the values used for previous days, it doesn't default them. Eg, if I take 2u Humalog and 8u NPH for breakfast on one day, it will use those values as the default for breakfast the next day, but it won't automatically select them; instead, I have to press the insulin button, add NPH, and add Humalog. Since the majority of the time I'm taking the same amount (or minor variation) of insulin each day, this is annoying.

    There's a serial cable to download the data, but it's Windows only. The charts and graphs that the app produces are nice, but I'd like the ability to be able to import them into the database of my choice, rather than having to open the Access file it generates. Also, the settings between the UltraSmart and the program are seperate; it doesn't transfer over (even one way) on the serial cable, which means I had to enter my ranges on the UltraSmart, and then again on the app.

    No numeric keypad. The Ultrasmart has the capability to record fat, carbohydrates, and protein entries, but it's a real PITA to enter the number "36" when you have to scroll to it (also, no way to enter exactly what it is that you ate, but a keyboard may be way too big). Hence, I don't use this feature at all, which is too bad.

    My mother is blind due to diabetes-induced glaucoma. She is stuck using a crappy end-of-life'd One Touch Profile [lifescan.com], because all of the new, nifty meters can't be used by blind people (that is, there are no devices to help them guide the blood onto the strip, there are no voice boxes available, etc.). It's a serious issue that most of these companies (One Touch, Accuchek, Freestyle, etc.) never address. How many diabetics are blind, people? A good bunch. Why don't they design monitoring devices for their use too?

    Personally, I have a One Touch Ultra Smart [lifescan.com], and I love 90% of it. I hate the fact that I can't edit the labels for "Health" and "Exercise" for instance. I love the graphing. I love the capillary-action strips. The 5-second test time is amazingly convenient, as well.

    My dad uses an Accuchek [accuchek.com] of some variety--he swears by it, even though it takes 10x as long for him to get a reading than I do.

    I'd love to see something that has a built-in voice box for blind people (seriously, how hard would this be nowadays??). I'd love to see that same model allow them to use the newer capillary-action strips, as well.
    • Check again, there is an Accu-Chek brand meter for people with limited or no vision - it's called Voicemate [accu-chek.com]. It reads the barcode on insulin vials as well to make sure the patient has the right bottle.

That is to day: put the mechanics on a pcmcia card, compact CF appliance, or even a modified SDIO card. Then wrap it in a really simple meter that just gives you a one shot readout. All too often, the data goes into a 'proprietary trap-door' in that the patent can get it into the meter (a major accomplishment for many) but the clinic cannot access the data because that can't afford the plethora of cables/cradles/ports and or software products to access the data and do something useful with it.

I usually don't bother except for one dump just before visiting the endocrinologist, and that's usually only good for averages since I can't be arsed to keep the clock accurate. (My Glucometer's clock drifted BADLY, the Accu-Chek's battery compartment is too loose and it completely loses its time frequently.)

      Implement wireless Palm HotSync-style syncing.
  • Type I here, Minimed Paradigm 511 and One-Touch Ultra.

    Minimed's new pumps have RF interfaces (better than infrared - no line-of-sight), and there's a meter that can integrate with the latest pump to automatically calculate boluses. Extremely cool, I want one.

    What I would like is completely automatic downloading - I sit in front of my computer, and it transfers all of the blood sugar and bolus data. I can deal with a few clicks to actually print it out, but I wish the download itself was completely aut
  • If you can create something like this [glucowatch.com] without the high price, I and millions of other diabetics will pray to you. Imagine: Inexpensive glucose monitoring without bloodletting. These guys did it, why can't anyone else?
    • I have one of those sitting in my collection. The reason that no one else did it is that is sucks in the most egregious way. It can be wildly inaccurate and It can give you a painful rash where it monitors because it is not really non-invasive. I tried it for a week before I took it apart. And no I'm not just bad mouthing the competition.

    Type I diabetic here; I use an Accu-check and take my insulin from a Humalog pen.

    Things I would like in my PDA (Personal Diabetic's Assistant):
    • no test strips. They are fscking expensive. There has got to be a way to check blood sugar without strips. Non-invasively would be optimal.
    • a scale. I don't count my carbs like I should, and part of the reason is I have a hard time estimating how many ounces of pasta I've got on my plate. A small portable scale would be nice.
    • wireless data transfer. IR woul
    • Since this is a poll I don't feel bad about saying me too, but I have a couple minor changes.

      It's not necessarily strips that matter, but overall cost. Monitoring is very $$$ intensive now.

      Continuous monitoring would be VERY nice. If not continuous monitoring, something that was convenient and cheap enough that I could test every twenty minutes or so would be great. That pretty much rules out an invasive meter; I wouldn't poke myself that often under normal circumstances. Bonus points if I can attach it

      • Last year I participated in a test of a continuous metering system at the (academic) hospital where I go.
        It definetively wasn't non-invasive, though! The metering was by measuring some properties of a fluid that was pumped through a tube (containing some sort of reagent (sp?)) that was looped through, ehm, me.
        The measuring device itself was rather big, too, but in a research sample, that's only to be expeced.
        The device still had quite a few problems, especially with the tube getting easily dislodged. It did
  • T1 for, um, a decade or so. I use an Esprit Glucometer (now sold as an Ascencia I think), lispro (Humalog) with a pen, and currently glargine (Lantus) with a syringe. I don't mind testing at all, it's no problem, but y'see I still don't do it. The reason is I'm lazy, and forgetful. What I really need is an insulin delivery device combined with a glucose measuring device and a lancing ("finger prick") device. They don't have to interact with each other, just as long as when I have the insulin pen in my
      • Interesting, but I see a few problems

        First it looks huge, I'm sure they could make it much smaller if they tried. When I'm going anywhere I can easily through my Esprit into a pocket (it's about the size of a pack of cigarettes (not that I smoke)), I don't think I could do that with this.

        Second, no lancer built in, this renders it much less useful as without a lancer built in I'm much less likely to test.

        Third, the screen looks vulnerable (admittedly, no more so than a cell phone's or PDA's), the Esprit
  • ...but my idea for a diabetic testing supply would be a small device that was implanted along side one of the user's veins, where it would have access to the blood stream. This device would then have a short range wireless interface that allowed the user to monitor their blood glucose levels without needing to draw blood.
    I thought the the idea would also hold great promise for body builders or anyone else who was really concerned with controlling their nutrition.
    As far as I know I haven't seen anything like
  • Get a meter and use it yourself for two or three months.
    Find out what is a pain and what is not about using one and go from there.
  • but, having been exposed to the Atkins diet, and being somewhat overwieght, Id love to monitor my own blood sugar to correlate against the foods I eat. With the prevelance of fast food, its damn difficult to pick out low GI carbs. I want constant, non invasive, blood chemistry monitoring gadgets - they must be simple, but programmable.
  • My wife has reactive hypoglycemia- which appears to me (an engineer) as an under-damped differential equation- if her blood sugar goes too high too quickly, it will then go low quickly, which has led to intoxication like symptoms, and occasionally, unconsciousness.

    A device that can accurately measure rate of change of blood sugar would go a long way towards helping her out- since it could help her predict and avoid the dangerous crashes. Right now, the only way is with test strips, and as many have pointe
    • Matt, if your wife's diabetes is that out of control she will develop permanent vital organ damage.

      She needs to go to a Doctor NOW, who should send her to a diabetes educator, who should have her also consult a dietitian. Diet and exercise (life style) are the only known methods of stabilizing (or damping) her condition.

      If it was my wife I would not go to work tomorrow I would take her to where ever my insurance would allow and I'd do it before lunch (being that's it's 1 in the morning here as I type).

      • Well, all that has already been done (including endocrinologists saying "that can't be happening", and "your glucometer must be wrong, your blood sugar can't be that low and still be conscious" and then it checks matches what their hi-tech super doctor's office stuff says). Her blood sugar is under control now (keeping to a low carb diet and monitoring the amount of carbs/meal)... mostly. At this point, there doesn't seem to be anything that medicine can do- her pancreas does work, but just not on schedu
        • You don't mention her regimen, but it's easier to control glucose with basal/bolus than with split/mixed. Important thing is to ensure that the basal dose really is. Fast all day (10-15 hours) to be sure, adjusting the basal dose until glucose stays steady-normal all day with just the basal dose.

          Lantus and Glargine aren't good basal insulins, because basal need changes during the day. I use NPH, which has a small peak to handle the dawn phenominon [at least if you take it near midnight]. Expect 4 tim
          • Her endocrinologist has called it "type 1.5" and has categorically refused to prescribe insulin, citing a very real possibility that it could kill her- her pancreas *does* produce insulin (so she's not type 1 as I understand it) and her body can use the insulin she produces (so she's not type 2 as I understand it). But we have seen her blood sugar go from over 200 to under 70 in less than an hour.

            I don't have her test results handy- but mostly the endocrinologists are left scratching their heads.

            Thankful
            • Ah, I had presumed Type 1, which is my specialty. Your MD is probably correct in holding off on insulin for now, but she may well progress to Type 1 and need it eventually. See http://www.diabetesnet.com/diabetes_types/diabete s _type_15.php for a description of Type 1.5. This is a good site in general, run by a Type 1 friend who is also a diabetes educator. His book, Using Insulin, is a very good one for Type 1 patients.

It combines a OneTouch Ultra meter with the Novo Nordisk insulin pen. http://www.lifescan.com/products/meters/induo/ [lifescan.com]

    Also there needs to be more software for Mac users. I used to use Vigora's DiabetesMentor which would grab the data from my meter but it hasn't been updated for OSX yet and it looks like it never will be.

  • Multiple strips are a must have for any diabetic on the go, the smaller you can make the meter the better, but the display needs to be easy to read. One word, BACKLIGHT. Glucose tracking is a must, advanced displays for tracking are nice but are usualy better for a desktop computer or palm app that can communicate with the meter (I know that I personaly never even look at the memory on my meter except to see if I remembered to do a test).

Obviously I have no personal experience with either type of device you mentioned, but one thing I've seen from my own research is that people who may have comorbid diagnoses are often going to require medical devices whose user interface is more flexible than that of an entertainment device or a device meant to be operated by medical professionals.

It should talk to my PDA and my MAC laptop preferably without a cable or have a pull out connector.

  • I am IDDM for about 15 years. I have used mostly some model of Accu-Chek and currently using the Active because the test strips are least expensive. I would like to see a meter that uses light or sound passed through the finger to read glucose levels. Light sensors are already commonly used to measure blood Oxygen levels. Seems like something similar could work for glucose.
