Early closing 12 months, my circle of relatives was once thrust relatively all of sudden into the sector of sort 1 diabetes (T1D). We spent virtually every week within the health facility stabilizing my daughter and finding out a ton about managing the life-threatening illness that will be along with her for the remainder of her existence. We’re within the early levels of a protracted, tricky adventure, however it’s protected to mention that we’re appreciative of the entire robust, leading edge T1D control advances, each medically and technologically.

Diabetes Sort 1 and Managing the Lifestyles-Threatening Illness

Let’s communicate concerning the pancreas (and the remainder of your frame) for a second. Its task is to continuously tweak its biochemistry to stay blood sugars in a typical, wholesome differ. Say you ate a burrito for breakfast, lunch and dinner – your pancreas is dealing with that like a champ, figuring out how a lot of its carb-processing energy – insulin – it must dispense to transform the ones burritos into power your frame can use. Charting blood sugar through the years, even for the craziest of foods, is like taking a look at a super bell curve, with a quite small top.

It’s now not like that for an individual with sort 1 diabetes. Now not even shut. Since their pancreas can’t produce insulin, the sugars from their foods proceed to pile up within the bloodstream. This creates a momentary emergency possibility in addition to long run well being deterioration.

As you’ll consider, managing T1D revolves across the real-time day by day tracking of my daughter’s illness, maintaining a tally of meals consumption and blood sugar ranges and figuring out whether or not motion must be taken or now not.

What I Set Out to Clear up

It’s by contrast chaos and uncertainty that my spouse and I struggle every minute of the day. On the other hand, existence for diabetics has modified considerably for the simpler. With the advent of technological developments just like the insulin pump and steady glucose track (CGM), existence has gotten more uncomplicated for each diabetics, and in our case, the oldsters of diabetics. We will see our daughter’s blood sugar ranges at any second, regardless of the place we’re positioned. Each five mins, the CGM transmitter sends the present blood sugar degree to a telephone within reach, which then sends that information to the cloud. IoT at its finest!

However, there’s a limitation. That information isn’t arriving as speedy as we predict it to and doesn’t pass precisely the place we would like and want it to be. We would like it in realtime, and we would like it on as many linked gadgets as we require.

As an example, at the supply facet, I will be able to’t be choosing up my telephone continuously. Or observing a internet web page someplace. Or casually glancing at my smartwatch. I would like that singular worth, my daughter’s most up-to-date blood glucose degree, available by way of many channels, from telephone to smartwatch to iPad to pc to no matter different gadgets I wish to attach.

Dexcom, the makers of our CGM, has achieved a considerable task with their product, and it improves with every unencumber. However, in spite of the development, and in spite of their monitoring and reporting capability, they haven’t invested sufficient into the on the spot, real-time streaming of blood glucose degree readings to any choice of more than a few kinds of gadgets and interfaces. So, I got down to handle this limitation.

Fortunately, T1D has a forward-thinking and collaborative selfmade neighborhood. From interpreting Bluetooth transmissions to create new control apps, to opposite engineering conversation protocols for insulin pumps, to development the primary usable synthetic pancreas, to robust real-time visualization apps, builders are discovering new techniques to control the illness, and feature shared it with the neighborhood.

Running with a real-time app platform (at my day task) let me suppose in a different way about architecting one thing like this, and allowed me to concentrate on the “industry” downside I used to be seeking to remedy. The place was once information being despatched from? To whom must it pass and during which manner? Will have to I increase the information with, on this case, further statistical aggregations? Will have to I retailer it as neatly in a database, for longer ancient perspectives? I spent manner much less time excited about servers, API frameworks, logging and tracking, and extra time answering the questions that inevitably made the day by day control of my daughter’s Sort 1 Diabetes that a lot more uncomplicated.

Construction My Personal T1D Control Answer

I set forth, harnessing the ability of the open supply neighborhood, with one goal in thoughts: to have the quickest, maximum protected, scalable, resilient and versatile resolution for me to peer my daughter’s ever-changing blood glucose ranges.

My function was once to create a era stack to flow updates from my daughter’s CGM to an ever-growing record of end-user packages, together with however now not restricted to, MS, push notifications, Slack, IoT lightbulbs and any interface I and others have interaction with all through the day.

Why such a lot of end-user apps? I’ve a existence to are living myself. I’ve to visit paintings. My spouse and I each want to devour this information and updates, and it must be the very same information. I will be able to’t be taking a look at my telephone always. I want to know the instant there’s a possible downside. Most significantly, I want to know that I’ve essentially the most up-to-date information to be had.

The whole lot begins with the Dexcom CGM firmly planted on my daughter’s abdominal and has a positive filament inserted into her tissue. The CGM communicates at once to her telephone by way of Bluetooth, and, each and every five mins, an up to date studying of her blood glucose degree is distributed to her telephone.

With my DIY resolution, I’m ready to cause an SMS/textual content message via a third-party provider. That is how I’m ready to ship each and every new studying to Slack. And, it’s how I’m ready to switch the colour of an LIFX gentle bulb relying at the quantity. After I’m in my bed room and my daughter is asleep, and I’m studying a e-book or looking at TV, taking a look at my telephone with every replace takes me out of my focus. Leisure on the finish of a protracted day is difficult to succeed in!

I added the LIFX Web-connected lightbulb to the answer, which adjustments colour and brightness in line with my daughter’s blood sugar ranges. Pink method prime, inexperienced method in-range, blue method trending low, and extremely vivid blue method low and motion required. It’s had an enormous affect on my spouse and my nightly regimen. And it best took 15 mins to enforce, begin to end.

The emotional receive advantages has been implausible for my spouse and me. The entire perception of me with the ability to see the information the instant it comes off my daughter’s CGM is very large as a mum or dad. From there, I will be able to simply distribute that quantity to an ever-growing choice of packages I have interaction with, proceeding to reinforce how I devour it in a extra environment friendly, much less disruptive manner in my on a regular basis existence. That information is anyplace I would like it, every time I would like it. I sit up for proceeding including new end-user packages, bettering my resolution and bettering how my spouse and I set up my daughter’s T1D. And I’ll proceed to percentage and watch with pleasure because the DIY, open-source T1D neighborhood grows.
