When the ice bandage is opened and ready to be used, the chemical reaction that triggers heat absorption
begins to cool as the salt containing ammonium ions and the water squeezed from the inner bag start to act.
For emergencies concerning sprains and contusions on sports fields, the frozen reaction is triggered
immediately as the rolled bandage is pulled away, hence providing the the function of an ice compress
immediately. The bandage strip can be attached according to the needs of the injured area.
1. It provides the function of timely ice application and attachment.
2. It is lightweight and easy to carry.
