XStat is a plastic syringe filled with 92 small sponges. In case of injury with his help, an injection is made directly into the wound, and after 20 seconds the bleeding stops. As you know, before the blood had to stop using special gauze. At the same time, there was pressure on the wound, which caused the victim unnecessary pain.
The sponges with which the syringe is filled are made of cellulose based on wood pulp, coated with chitosan, a substance contained in the shell of some crustaceans. Scientists have long known not only the unique antibacterial, but also thrombogenic properties of chitosan.
Once inside the wound cavity under some pressure, the sponges stop even very strong arterial bleeding. Each syringe can absorb up to 473 ml of blood. There will be no problems with the subsequent removal of sponges from the wound, as they are clearly visible on X-rays. However, in case of severe injuries to the chest, abdomen, pelvis or in the collarbone area, the XStat 30 is not effective.
