The pressure from the expanding sponges should be enough to stop the bleeding in most vessels.
Though if it's a nicked or ruptured artery it may only work once volume of blood is low, i.e. pressure.
Like you said though, evaluating the wound once in a hospital setting will be too time consuming, and life threatening at that point. Not to mention the chance of an embolism from the negative space in the sponges themselves. All the air has to go somewhere.
As a person that has treated a GSW I would have to say that this would still be a better option than just applying pressure, fluids, and oxygen. Or at least something I would like to have in my kit.
As for the price, I remember hearing that these can be produced for around $10 USD.

Edited by bobcast: 6/3/2014 6:22:52 AMNot to be a dick. But literally nothing you said makes physiological sense. The human abdomen can hold liters of blood without creating enough pressure to tamponade the bleeding that caused it. Those sponges will not help in any bleeding with the abdomen. I don't think you have any clue what an air embolism is or how they form. In any case, this is not the type of injury or circumstance that would cause one. If you have actually treated a GSW, would know it is a waste. I doubt you have seen any. I'm an Emergency Physician. This is my bread and butter.

With open neck wounds you have the risk of pulling air in through the arteries. With all the negative space in the injector, you could accidentally inject air into the neck wound. Yes, the abdomen can hold almost the entire volume of blood in our bodies, but that doesn't mean that it always does. I could see these working best for a piercing pelvic injury. Especially in the iliac crest.

1) Arteries are a positive pressure system. They will not "suck in air." Veins are a negative pressure system, and can pull air in. In the event of a neck wound, you would have to worry about one of the jugulars pulling in enough air to cause an air embolism. As an FYI, you need over 100 ml of air before you even need to get worried. 2) The abdominal cavity has a relatively huge potential space. If all your blood is in this space, you die. 3) This is device would do nothing for a pelvic injury, especially a piercing pelvic injury. The pelvis has a huge and complex venous plexus that bleeds like stink when there is pelvic injury. See above. Also, bullet plus bone doesn't = cute little hole, especially military grade high energy rounds. Those injuries result in shattered bone where the bone fragments turn into projectiles themselves. Aside from all this, I pulled up the FDA approval at work today. The device is contraindicated for any injuries in the thoracic abdominal and pelvic cavities, any injuries superior to the clavicles ( so all head and neck wounds), and the retroperitoneal space.
