An Oregon startup company called RevMedx has invented pocket-sized tubes filled with tiny sponges that help seal gunshot wounds in just 15 seconds.
Tiny sponges made from wood pulp and coated with chitosan, a substance found in shrimp shells, are biocompatible, fast expanding, and capable of stopping bleeding. The syringe comes in 30 millimetre and 12 millimetre sizes. — Reuters
