Artificial Pancreas Bluetooth Based at JDRF T1 Now Conference

Here it is!! This is a shot (I only got one chance, so excuse the glare) of a smartphone that has an artificial pancreas program installed. It uses Bluetooth to take data from your CGM and your pump (Bluetooth enabled...hello Medtronic?) and combines the data into a program that can determine whether you need more insulin or less.

It watches your blood glucose and that gives micro blouses if you are trending high, or micro-suspends the pump to stop delivery of insulin in you are trending low. I wish I had the chance to get shots of all the screens, but one screen shows the CGM data in a graph and also how the pump is told to react, so you see the micro-blouses like a bar chart by hour/minute and also how the pump will suspend for short periods with the bar graph that goes below the line. So you see everything.

On this screen you can see it is connected to the CGM and the pump. You can see the "Closed Loop" is active. You have screens for adding food, medications, or exercise. He explained that much like autopilot on a plane, as captain, you want to take off and land the plane yourself, so you are active in the process of blousing for meals. But, if you are like my tween and forget, the AP will watch you trending high and bonus to keep you in target range. This is harder for your body than just planning and blousing, but let's say that pizza was really 45 carbs and not 60? The AP will watch you dropping and suspend insulin delivery to stabilize you. I bet that may not be enough in some cases, but what a help.

Tom Brobson, National Director for JDRF, who showed me this device, told a story about how when he got this thing, he went straight to a burger joint and ordered a huge burger and a huge order of fries. He said he took about 2 units of insulin for that huge meal and watched what would happen. You know what? He never got above 150 or so. The AP worked great at trending and anticipating his bodies needs.

The unit he was showing us was in a simulation mode now. But THIS is exciting. When he used the functioning device, he used it with his Omni Pod and his Dexcom G4 Platinum, both Bluetooth enabled.

While I had Mr. Brobson's attention, I proceeded to have a little rant about the FDA and Medtronic Minimed. More about the results of that conversation in my next post, but I feel better.

The AP is a great idea. The associated cost of the device will be a reality reality check. For me, the cost of the insulin pump and sensors were prohibitive for me. The " affordble health care" act will be fully enacted next year, the insurance companies will push all the associated cost to the end users.
