their lives to safeguard the security and integrity of the nation. It is
therefore our prime duty as citizens of the nation to take good and adequate
care of the soldiers both at and off the war field.
developed a foam injection that can slow down the blood loss of the wounded
soldiers before they can be taken to the hospital. Such foam injections promise
in protecting the soldiers from internal bleeding which is regarded as the main
cause of deaths before the wounded soldiers can be taken to the hospitals for
After a number of
failures, the researchers at Arsenal Medical Inc have formulated a spray foam
which when injected in the abdominal cavity of the wounded soldiers, can stop
internal bleeding. This gives them a protecting coverage by the time they can
be taken to the hospital for advanced treatment.
This is how it works -
two liquid phases, a polyol phase and an isocyanate phase, are injected into
the abdominal cavity, which on mixing inside the body trigger a reaction to
form a polyurethane polymer (foam) that moulds around the injured organ and
resists blood loss.
The researchers have
successfully tested the efficacy of foam injections in stopping the internal hemorrhaging
in pigs for up to an hour.
Brian Holloway, the
Program Manager of Defense Advanced Research Projects Agency (DARPA) mentioned,
"If testing bears out, the foam technology could affect up to 50 percent
of potentially survivable battlefield wounds."
This technology could
be useful not only to the soldiers but even to civilians wounded or injured in
a serious accident and far away from the hospital.
About $15.5 million
was awarded by the Pentagon Agency to Arsenal Medical Inc in order to develop the
important medical foam after the prior successful testing.
The research is funded by the DARPA Wound Stasis
program which began in 2010.
