Abstract: This disclosure provides a portable hemostatic bandage system, which comprises two formulations comprising siloxanes and blowing gas generating agents as well as a dual container device, optionally a dual syringe applicator, for in situ construction of a sponge-like polymer foam as hemostatic bandage material. Two formulations kept separately in a dual container device react instantly with each other when forced to mix, and as a result, decomposition of hydrogen peroxide occurs to generate a blowing gas O2 and heat, and consequently siloxane polymer curing occurs to form polymer foam inside the dual container device. When the blowing foam is applied to a bleeding wound, it forms a sponge plug within a few minutes to control hemorrhage. This portable hemostatic bandage system can be easily used at ambient temperatures, and it is a cost-effective method to control hemorrhage.
