RevMedx, a medical technology company in Oregon, USA, developed a syringe-like medical device named 'XStat' with a built-in mini-cotton swab that changed the way that the medic could treat gunshot and shrapnel wounds. When in use, dozens of pill-shaped micro absorbent cottons are injected into wounds by the military medical personnel and are treated by chitosan. Chitosan is capable of clotting blood and fighting infections. In a few seconds, the cotton wool can expand ten times, close the wound and stop bleeding. However, the method of stopping bleeding by means of blood-sucking expansion is very dangerous for the wounded with big hemorrhage in the battlefield, and the strength of the material is weakened after the material is expanded, so that the material is difficult to provide continuous extrusion force on the wound surface, and the function of the material needs to be further improved.
