prefill syringes?

I use a frio wallet, soak it in cold water for a few minutes and it keeps pens and insulin cool, available in different sizes from frio UK or Amazon.

You could look at the "MyLife DailyDose" syringes from the makers of omnipod. They are single use, single dose syringes that you are supposed to prefill and carry with you.


Medicool: PenPlus range
Medicool has a range of bags that include insulation such as the PenPlus case which can protect valuable supplies. Useful for men, women, children, seniors, and medical personnel it can be attached to a belt, placed inside a purse or briefcase, or carried by its detachable hand strap.

It can be used for either insulin pens or those who use insulin vials and injections keeping them cool for hours using a refreezable gel pack.

This case can hold up to four vials of insulin or two insulin pens keeping them safely cool for up to 12 hours.

i have f'ound the Frio bags work very well in hot weather. They rely on evaporation so should be allowed to have fresh air around them so the water can evaporate.
