Liquid injections create foam that stop internal bleeding…
DARPA has unveiled a new polymer foam that can be injected into the body to stop internal bleeding in areas of the body that cannot be compressed by a bandage or tourniquet
The new Wound Stasis technology, develop by Arsenal Medical with funding from DARPA, works by injecting two liquids into the body. When these two liquids meet they being a chemical reaction that creates a foam, which presses against the internal wounded to slow the flow of blood. Once surgery can be performed the foam can be easily removed in under a minute.
Almost 85 percent of battlefield wounds are due to internal wounds that require surgery. Often there is not enough time to get the wounded to a hospital, or somewhere they can receive the correct medial attention. The new procedure can provide an extra hour of precious time before receiving this medical care.
During tests on pigs, DARPA claims the foam can increase changes of survival after three hours from 8 percent to 72 percent. Arsenal Medical is now working on a commercial version of the device while DARPA is seeking FDA approval.
