CTI BlindSpotz™ Printable Sensors Keeps Meds Safe

Updated: Oct 21, 2021



An alert pops up on your phone: Your insulin has been delivered and conveniently left on your doorstep … in the southern-facing afternoon sun … on the hottest day of summer. No one is home, and you can’t reach your neighbor. By the time you get home, the package has been sitting for a few hours.


The FDA website says, “Note: Insulin loses some effectiveness when exposed to extreme temperatures. The longer the exposure to extreme temperatures, the less effective the insulin becomes. This can result in loss of blood glucose control over time.”


How do you know if it got too hot?


BlindSpotz Heat Alert technology changes color when exposed to heat greater than 43°C / 109.4°F, giving a definite answer.


What if it’s a cold winter day? BlindSpotz Freeze Alert, you can easily see if your insulin has been exposed to freezing temperatures during transit. If it has, you shouldn’t use it.


BlindSpotz sensors differ from temperature data loggers in that they’re a printable technology, allow fully customized designs, and are inexpensive enough to place on every insulin injector.


Do you supply or transport temperature-sensitive medicines? Contact your CTI team to see if BlindSpotz Heat and Freeze printable technology can add safety and security to your customer experiences.


By the way, CTI also has a specially designed printable sensor called SafeInject to show that insulin is warm enough to inject via pen or infusion device without pain and in the correct time span. There’s also our Thaw Alert and combination Thaw Alert / Warming Alert sensors for vaccines that need to be deep-frozen below -20C for storage and transport, then thaw to a maximum of 8C for use in a limited time period.
