I attended a workshop offered by 3M, Sept 12/13, 2011 in Toronto.
I have learned their new cohesive bandage and its application.
Coban2 is a new type of compression bandage.
It coheres to each other and stays on the skin very well. It is less bulky and less heavier compared to traditional compression bandage. It is not reusable and it can be worn up to 7 days without being removed/reapplied.
The regular (traditional) compression bandage is reusable and it has to be removed and reapplied everyday.
