Several other external hemostats (literally blood stoppers) exist and have been in service for several years now. QuikClot (http://quikclot.com/) being one of the first I became familiar with. Army has been using these on the battle field for several years now. The question is how much faster is this polymer. Several current external hemostats are available as gels powders and bandages on Amazon now ( http://www.amazon.com/s?ie=UTF8&page=1&rh=i%3Aaps%2Ck%3Ahemostatic%20bandages ). I have carried QuikClot in my SAR emergency med kit for several years now. External hemostats have a valid place in trauma med kits and are available now.

Will the polymer hemostat be an investment opportunity? Could be, it depends on how much better (faster) it is than existing products, how expensive it is, and how long it takes to get to market.
