If you mean the Celox A applicator, yes I have, Very effective, still needs pressure though. It contains the normal Celox haemostatic granules (not expanding sponges). The syringe applicator enables the MEDIC to get the granules to the point of the bleed more effectively than pouring it in and is easier/quicker to use in some circumstances than wound packing in certain injuries,
I have also seen a prototype of the xstat system when working with an American colleage working for the DEA in a foreign land.
Its the one that uses small sponges, At that time it had not been approved for general medical use, but it did work well on wounds too big for the Celox A. The Xstat coming in two sizes.
With Celox (round) bandages it is a common civilian layman mistake to use the haemostat impregnated bandage as exactly that, a bandage! Its proper use is to pack wound to bleed site, ie IN IT not over it, secure AND then apply pressure for at least 3m. You are correct saying use as a bandage is wasted. Indeed the civilian medical profession in many places took a lot of training to use as intended and not as a bandage wasting its haemostatic properties.
You will appreciate in a tactical environment that sterile is something hard to achieve, where priority is to stop bleeding and the subsequent complications until medevac. Chitosan has a mild antibacterial property anyway. Infection control is not really a CMTs priority, more Offshore medic hat
I have used foams, indeed for dental issues on a yacht! i can see the advantage of an attached antibiotic too although there will always be contras..
I think we are both agreed, there is no point having anything in your bushcraft FAK if you do not know or have training to use it. I spend a lot of time now running courses on proper use of these products.
Knowledge is the lightest, most effective item in any kit.
