The Latest and Greatest in Insulin Pumps and Sensor Technology

diabetes pumps and sensors

I love pumps and sensors!

As a certified diabetes educator (or as I prefer to say, type 1 coach), I have started literally hundreds of patients on insulin pumps over the last few decades. I have a disclaimer: I do not wear a pump and do not have type 1 diabetes. But I have worked in the field from clinics to ski and summer camps, as a dog sled driver for little munchkins with our team of sled dogs, to backpacking and canoe trips – all with people who do have type 1 diabetes. Sometimes I grunt and groan when I get up to start an adventure, but then I meet up with the group and see someone taking shots! My emotions turn to glee when someone has a pump and a sensor…I realize it sometimes feels like being the bionic man or woman with all this technology but hey, what’s wrong with being such a diabetes stud or studdette?

So what is so cool about pump and sensor technology?

Well, if you’re like me and you like to participate in group sports or activities, the technology is amazing. Let’s say you are just starting off on an adventure (whatever that may be) with a group and you note on your sensor that your blood glucose (BG) is 50 mg/dL.

Argh.

Who wants to stop the whole team from proceeding? But then you realize you can take in some carbohydrates, lower your basal rate temporarily, and watch your sensor to see if you are coming up and are not only good to go, but where you will be in 5, 10, 15, 20 minutes…you get the idea.

What are the options available right now to help you manage your diabetes?

The Omnipod insulin pump is the only full functioning patch pump, meaning it is programmable with insulin-to-carb ratios, target BG, correction factors, etc. so your math is done for you. At this time, the Omnipod pump does not integrate with a sensor but you can certainly use the Dexcom sensor independently.

There are also two patch pumps that are not programmable and have a bolus only option (OneTouch Via) and basal/bolus option (V-Go). These are more likely options for those with type 2 diabetes.

The Tandem insulin pump does have a tube that most folks find a minor inconvenience. Its great new claim to fame is that, as the software is updated (and technology is changing so fast!), you can update your pump via the cloud. How cool is that! Your pump does not get outdated since the pump software is updated. This includes future changes, such as Dexcom sensor data on the screen, auto-suspend as needed with hypoglycemia, and the eventual goal of a fully integrated sensor and pump where the pump responds to the data from the sensor and alters insulin delivery.

The Medtronic insulin pump company has led the charge not only with a sensor integrated pump where the sensor data is seen on the pump screen, but where the pump responds to low blood glucose values and impending lows, and adjusts basal rates as needed based on your basal history. Be warned, this is not a cure and still requires diligence on your part or the system will fail. Fasting blood glucose values have been shown to be excellent – generally close to the pump set target range of 120 mg/dL.

You can always choose to continue with injections and utilize one of two sensors. Dexcom (glucose readings every 5 minutes on a receiver or your cell phone) or the new Freestyle Libre that allows you to scan your sensor patch and see your glucose on a receiver.

And where is all of this going?

Oh – it is so exciting! I am confident that in the next five years a fully automated system will be available with minimal input from the user. Tandem, Omnipod and Medtronic are all working on fully integrated pumps as responsibly fast as they can. In addition, other options are coming too, including a dual hormone system that has reservoirs for insulin and glucagon to keep you safe. And with the new insulin from Novo Nordisk that is reputed to start absorption in 2.5 minutes (wow!) one of the big barriers to insulin delivery may have just been resolved.

Although a cure is what we are all hoping for, technology is the next best thing.

Embrace it and stay tuned!

Uber’s Self-Driving Taxis Have Hit The Streets

IN BRIEF

Today, Uber’s self-driving autonomous cars began picking up passengers in Pittsburgh. In this first stage of testing, the cars still require a person to monitor progress and ensure that there are no issues.

As part of their bid to build an empire that consists of cars that drive themselves (yes, cars that drive sans driver), Uber just launched partially self-driving taxis. They started rolling along the streets of Pittsburgh today.

But don’t get too excited about taking one for a spin yourself, an engineer will be in the driver’s seat to get things started and make corrections if the car makes a mistake. And notably, the “partially autonomous” part is of importance, as  drivers are always supposed to keep their hands loosely on the steering wheel so they can takeover when needed. To clarify, the car is the one doing the driving, but humans are needed for oversight.

A touch-screen is located in the backseat in order to give passengers all of the trip details, and a “liquid-cooled” computer will also be on-board, recording trip and map data in the trunk.

Hoping to hire the taxi yourself? That may be difficult, as individuals will be randomly assigned a self-driving car when they request an UberX ride on their app. But! Passengers who take a ride in the experimental self-driving cars will get their trip for free.

Notably, Uber plans to install self-driving kits into existing vehicles rather than build fully autonomous cars from the ground up. To that end, last month Uber acquired Otto, a company that works on retrofitting heavy-duty freight haulers on the highway in order to turn them into self-driving trucks.

Otto’s LIDAR (light detection and ranging) sensor technology detects infrared emissions to help monitor speed, and is geared to be adapted for use in Uber’s autonomous vehicles.

The future, my friends, truly is now.
