Faster haemorrhage control

摘要

Aerogels made from waste cotton-based fabric can be used to control haemorrhaging, claim researchers from the National University of Singapore (NUS) Faculty of Engineering.Current haemorrhage control devices comprise a syringe filled with small capsules of cellulose-based sponge, coated with chitosan, a natural agent derived from crustacean shells that promotes blood clotting. The syringe is inserted into the wound to release the capsule, which expands and applies pressure on the wound to stopthe blood flow. According to NUS, the expansion and absorption rates of cellulose-based sponges are still relatively slow.
