Monitoring Insulin Temperature

Jun 27, 2017

I have type 1 diabetes and have been living with it for the past 11 years. I take daily insulin injections to stay alive and well. A couple of years ago, I had a very frustrating incident when my insulin stopped working. I began injecting loads of insulin, and even with multiple doses my blood glucose wouldn’t drop. I ended up going to the hospital but luckily without DKA. It was only later that I learned that my refrigerator failed to maintain the correct temperature to store my insulin. It turns out that my insulin had frozen while in the refrigerator, which totally destroyed its potency.  It was a very frustrating incident, or accident, especially because it should be such an easily solved problem.

In fact, pharmaceutical companies and distributors have a “cold chain” process that monitors every batch of insulin for temperature excursions from the point of manufacture through the time it is sold to the patient.


Unfortunately, I discovered that the cold chain ends there. I searched for an existing off-the-shelf  solution to this problem and was unable to find one. I thought it was not a technology problem but some other issue. So I decided to make one.

The solution I developed is a very practical and easy-to-use device. It is a wireless temperature sensor that continuously measures the temperature of insulin or any other labile medication. The solution is to place the sensor with the insulin, whether it is in its case or in the refrigerator. The sensor is wirelessly connected via Bluetooth to a mobile application that is downloaded to a smartphone. The phone application reads the temperature from the wireless sensor and every time it is too hot or too cold it sets off an alarm.

It has a very easy-to-read user interface to understand when the medication is too warm or too cool. It has a drop-down menu that once the specific medication is selected the application automatically calibrates its settings for the safe range of your selected medication.
