I have not done much research on this product yet. There is new info that talks about the pressure difference from inside a wound to the outside and that it helps control bleeding. This idea with the sponge and chitosan may take advantage of the pressure and hemostatic agent for hemorrhage control. I am not sure what duration of direct pressure is needed with this product (remember most Hemostatic Agents need 3-5 minutes of direct pressure after application), it says 15 seconds. . . . but let's see.

It looks like a promising product, let's see some good third party (USAISR) testing against Combat Guaze, and if it works get in TCCC and in the field.
