The Need
In the case of DBAC the US DARPA recognized
a need to the save lives and limbs of soldiers
in the field in the absence of a full medical
team. DBAC aims to satisfy this need by
creating a device that requires minimum skill
and delivers maximum results.
Current Methods

Chitosan Bandage by Hemcon

made of shrimp shells and sticks to the
wounded area, sealing it off like a tire patch
Current Methods

QuickClot by Z-Medica

made up of desiccant granules that
physically adsorb the liquid from blood
Introduction




DBAC is a New Medical Technology
It is a 4 year Project that Began in 2006
A Collaborative Project that Involves
University, Government, and Corporate
Research
Developed to lower casualties in the
Field
The Corporations


July 2006 Phillips announced that it would
lead phase I of a planned 4 year US DARPA
project.
Phillip’s intended to develop a new medical
technology, that would automatically detect
and stop internal bleeding.
The Corporations


In 2008 Siemens entered into an
exclusive contract with DARPA to
develop the DBAC.
18 month projected completion of the
DBAC Cuff prototype.
HIFU


The development of high intensity
focused ultrasound (HIFU)
HIFU is currently used in other areas of
the medical field and has had success.


