Trauma Patient Tracking System
A hardware and software platform to track and
monitor Trauma Patients from the point of initial
care though hospital treatment

• Why
• Accurately record the amount of time from trauma
  incident to operating room treatment
• Monitor patient location during pre-hospital care
• Coordinate logistics during a mass casualty event
  
• Track exposed population movements in biohazard
  or other contagious event

System Requirements

• Low Cost, Ubiquitous Tracking Devices
• Wrist Wearable Size, Weight, and Wear Method
• 48 Hours Battery Life
• Reliable Positioning Methods
• Track Patient Continuously Once Tagged
• In-hospital Positioning
• Robust Tracking Capability
• High Availability Internet Connectivity
• Multiple Communication Systems
• Tracking Software
• Real-Time Tracking
• Location and Contact History and Traceability
• Biomonitor
• Determine Life Status

Triton Approach

• Complete System Design
• Create an engineering solution which uses
  available COTS hardware to deliver a complete and
  functioning TPTS system to Army specification
• Open Platform Solution
• Meets the current Army requirements
• Easily incorporates new technologies solutions
• Easily adapts to related applications
• Allows other vendors to supply hardware (e.g.
  Patient Tags) or services (e.g. Internet access)

Trauma Patient Tracking System
Base Stations connect to Tags via short range
wireless relay Tag data via multiple Internet
connections
Tag data collected and made available for real
time tracking historical analysis
Tags given out at point of care

Pre-Design Determination

• Assessment
• Technology areas included in this design are
  under rapid transition and evolution
• Optimal approach is to make solution independent
  of specific technology
• Develop a universal telemedicine platform for
  portable, low power applications
• Modular Design
• Use Technology with most Market Pull
• Design components as subsystems
• Apply basic architecture to similar applications
