Diabetics are hacking old insulin pumps to make them smarter — here's what happened when I tried it

There is a revolution in the Type 1 diabetes community and thousands of people are now hacking their insulin pumps for better blood sugar management. CNBC's Erin Black, who was diagnosed with Type 1 diabetes 20 years ago, decided to try out the hacked system. Here's what happened.

Type 1 diabetes is a disease that affects more than 1.2 million Americans. I'm one of them. It's a disease that impairs the body's ability to produce the hormone insulin, which normally comes from the pancreas. So insulin has to be injected.

Managing blood sugars can be very difficult, and patients use a pump to help mimic the activity of the pancreas. However, pumps don't automatically adjust insulin levels for diabetics. And the manual process is tedious and can be dangerous.

But a few years ago, people figured out how to hack their insulin pumps to make them automatically adjust insulin levels more precisely.

      I really can't read youtube and would normally appreciate a text/transcript

      However, all I can see on the text page you linked is:
      - TFS; +
      -

      While there is now an FDA approved commercial product available — made by Medtronic — there are still thousands of Type 1 diabetics that are turning to hacking to get better blood sugar control. I wanted to explore why.

      Here's what happened when I put this do-it-yourself artificial pancreas system to the test.

      Dang! Not much more? So what good is that page?

            This sounds interesting. I'll read on.

            Wait??!? What!!?!
            That's awful!
            No, hacking it and hurting or killing yourself would be awful. Affecting 1.2 million other people? This is a weapon of mass destruction! It has to be illegal!

      transcript:

      Thousands of type 1 diabetics are turning a hacking to get better blood
      sugar control. I mean a cure in 50 years is not going to help me. I need this now.
      This is an insulin pump. No, it's not a beeper. It's a device that type 1
      diabetics, like myself, use to keep themselves alive. Type 1 diabetes is a
      disease that affects over 1.2 million Americans, where your pancreas does not
      produce any insulin, which is what regulates blood sugar. So we have to
      inject it using needles or a pump. Managing blood sugars is difficult and
      time consuming. I have to manually adjust my insulin levels all day and night.

      But a few years ago people figured out how to hack into some insulin pumps and turn
      them into artificial pancreas, which automatically adjust insulin levels as
      needed. Instead of the blood sugar going like this, the insulin is going like this.
      Sugar line is smoother and steadier. The Pressnall family decided to make a
      do-it-yourself artificial pancreas for their twelve-year-old daughter, Ella.
      After having to wake up multiple times a night to make sure her blood sugar was
      at a safe level. Pizza for us was a three or four time up in the middle of the
      night taking care of Ella a kind of situation. It was so exciting for me to see the
      OpenAPS make adjustments to her basal. There using the Open Artificial Pancreas System
      It's a free, open-source project that aims to make basic artificial
      pancreas system technology available to everyone.
      OpenAPS and the Loop app are systems that you can build on your own, for as
      little as $150. When you see the basal insulin getting
      adjusted like this and you see that in the course of the day that happened like
      300 times, those are three hundred decisions that you didn't have to make
      to keep somebody safe. I'd rather push that on to a computer that can do that
      then then myself. Here's how it works. The app hits your blood sugar number
      from the continuous glucose monitor and decides to increase or decrease insulin.
      The mini computer then converts the phone's Bluetooth to a radio signal so
      the pump can receive the command. The pump then automatically gives insulin,
      creating a closed-loop system, or what many call an artificial pancreas.
      I had to try this out for myself but I was still nervous to let my pump
      automatically give me insulin. So I called Dr. Earl Hirsch, who is a diabetes
      expert. He has two patients who are DIY looping. The cons are that it is still
      relatively new. It has not been formally tested by the FDA. We're using old
      insulin pumps as a rule of thumb, usually well past their expiration. Having said
      that I personally don't know of any major problems that have occurred.
      Mostly what I am hearing is people are extremely happy with their results.
      So I ordered all the equipment, built the system and gave it a try.
      The first night was pretty nerve-racking. Sleeping can be a tough time for people with diabetes
      because you can't feel low blood sugars in your sleep but the results were
      amazing. Every five minutes the system adjusted the amount of insulin I was
      getting and gave me a perfectly smooth graph. So here's what my blood Sugar's
      used to look like overnight before I hack my pump. And this is what they look
      like now. But there is a catch to this technology. The only reason this is
      possible is because a flaw was found in older Medtronic pumps that allow you to
      send external commands to the device. but Medtronic fix this flaw in its newer pumps
      and last year came out with a pump that works very similar to the hack system
      that I'd built. But unlike the DIY pancreas, this one is approved by the FDA.
      So we actually work with the FDA on an accelerated timeline in order to bring
      these hybrid closed-loop system to the market. The new pump platform was with
      the FDA for about a year and a half. The hybrid closed loop system was with the
      FDA for less than 100 days and so we were able to get that system out with
      cooperation with the FDA actually quite quickly. The 670G became available in
      2017, two years after many had already started doing it on their own.
      The company warned against using the hack system. It's almost like modifying your
      car, right? If you're going to take a personal risk to say this isn't
      regulated but I'm going to set it up, I'm gonna pick whatever settings and
      whatever happens, happens, then obviously without that risk that
      has flexibilities that are allowed. Medtronics is over 120,000 patients using
      the 670G system. So why hasn't everyone using a DIY system switched over to the
      FDA-approved one. For one, it cost about seven thousand dollars if you don't have
      insurance and children under the age of seven can't use the 670G. Plus, some
      people just like the DIY system because it's so customizable. We have the ability
      to move the features and make adjustments to the system very, very
      quickly. The types of clinical trials, so to speak, that we're able to do as a DIY
      group is infinitely flexible and very responsive to the needs of the actual
      users. This is what led a former Amazon software VP to start a non-profit to
      help people manage their diabetes. Now the company is on track to get this hack
      system approved by the FDA. 2011, our daughter Katie was diagnosed with type 1
      diabetes and I just couldn't believe how painfully terrible all of the software
      that came with her devices was. It was really crazy and I thought to myself
      this is ridiculous. Why doesn't somebody do something about it? There are a lot of
      people who are just nervous about building their own system. And we feel
      like you should be able to go to the App Store, download an app that you know is
      safe and effective. Tidepool's app will fix the flaws and give the DIY
      artificial pancreas direct communication to your pump. He couldn't tell me which
      manufacturers I'll be working with but the hope is that diabetics could choose
      any pump they wanted. As opposed to this old 2007 Medtronic's pump that I've been
      using. They're also several other companies with their own systems on the
      horizon. Many of which are expected in 2019 and 2020.
      I've been using the hack system for a few weeks now and I don't plan on
      stopping. My blood sugars are the best that they've ever been and it's required
      less effort from me to get them that way. But the system still isn't perfect.
      I have to carry around even more equipment than I used to, I still have to give
      myself insulin for meals and anytime there's a problem I really don't know
      how to fix it. That being said the positives far outweigh the negatives so
      I plan to keep using this hack system until a better option is available.

      It is not change of "settings" - I have pump. I have CGM. They do not work together.

      It is allowing a full feed back loop to form.

      Currently the pumps on the market that do have "feed back" are ominous to use and do not give true bolus and basil adjustments.
      Mainly they just turn off "safe mode".
      To make adjustments on all pumps the interface is very poor. A menu interface with no back button. So either force your way forward or wait 30 seconds for it to time and go back to the top.
      All products are highly silo-ed. You cannot use one CGM system with another.

      They are finally starting to give apps for your phone...
      These to0 are clunky and do not support all needed functions.
      Mainly they say, you are high or low. Not much else.
      No "rumble strip" to let you know earlier you are getting out of standard.
      Do NOT support current version of Os for 3 to 6 months after the release.

      Basically it is all your fault if something goes wrong. But paying up wards $10K/yr for CGM and $10k up front and $3k/year for a pump, you should not have to break into them an void any SUPPORT warranty.

      I have looked at IFTT and other tools to improve my sugar controls... but they are not there.

      Particularly so since usually this sort of thing is actually considered illegal circumvention of yadda yadda, and we're talking about a device that directly impacts your health.

          I would draw a distinction between

          A) Modifying your pacemaker/insulin pump voids the warranty and means you can't sue the manufacturer if it fails and harms you
          B) Modifying your pacemaker/insulin pump wins you a call from a lawyer and a DMCA lawsuit

          But this is the U.S. we're talking about, so inevitably one of these people will try to sue the manufacturer after modding.

      The pumps are not being modified.

      A transmitter that can talk to the pumps is being used.

      The transmitter exploits a flaw in old pumps that allows them to accept commands without any security.

      New pumps have security.
