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

4
Current Methods

• QuickClot by Z-Medica
• made up of desiccant granules that physically
  adsorb the liquid from blood

5
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

6
The Corporations

• July 2006 Phillips announced that it would lead
  phase I of a planned 4 year US DARPA project.
• Phillips intended to develop a new medical
  technology, that would automatically detect and
  stop internal bleeding.

7
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.

8
HIFU

• The development of high intensity focused
  ultrasound (HIFU)
• HIFU is currently used in other areas of the
  medical field and has had success.
• Prostate Cancer
• Uterine Fibroids

9
Device Design

• Compact
• Light weight
• Integrated electronics
• Cuff to wrap around/over the wound
