The Perfect Partner
For Your Insulin Pen
is the world’s first and only reusable
insulin pen cap temperature-shield that keeps
your in-use insulin cool. Have peace of mind
about your insulin with state-of-the-art
thermal insulation
technology and heat exchanger only found in
high-performance applications such as
spacecraft, avionics, and cryotherapy.
Our pen cap is proven to protect your insulin from damaging temperatures you expose it to, during the course of a busy day, when you’re travelling on business, or for vacation . So whether it’s summertime or winter, VIVI CAP1 ensures that your insulin is protected anytime, anywhere – it even fits perfectly in your pocket!
"Basically replaces my pen's cap and keeps my pen in a cooler, steady temperature. Easy to carry in my purse and I love the fact that there is no need to do anything like replacing a battery, charging and putting in the refrigerator over night"
"This has been the best product for me for when i have to travel and cant keep my insulin refrigerated. The technology is amazing and it really works well even when its hot out. Would definitely recommend."
“Great solution for ‘on the go’ insulin. My granny can take it anywhere without worrying about the temperature. A must have product if you’re diabetic”
How It Works
VIVI CAP1 is based on a patented combination of unique insulation materials and heat-absorbing chemicals with monitoring and control electronics.
When VIVI CAP1 is exposed to ambient temperatures above 29°C, slow transition of the PCM material from solid to liquid starts. This transition, due to the insulation, takes very long time to complete. During all this, the temperature inside the products, which is in equilibrium with the drug chamber of the pens or vials, is fixed to 28°C.
The user can monitor the temperature using the push bottom of the electronics which provide intuitive indication on the temperature of the drug.
Whenever the ambient temperature falls below 28°C, the PCM starts to return to its solid state again allowing it to regain its heat-absorbing property. It is enough for the products to remain overnight under such ambient conditions to reach that, without any actions from the user.

Hear what world-renowned, multi-awarded, Yale Chief of Pediatric Endocrinology, Dr. Tamborlane, has to say:
“I am delighted to have this opportunity to endorse the use of the VIVI CAP1 to maintain optimal temperature control of temperature sensitive drugs. As a clinician and clinical investigator concerned about better treatments for diabetes, the VIVI CAP1 will be of particular benefit for my patients who require insulin shots, as the vast majority of patients use insulin pens for their daily injections.”
