Problem being solved
• Detecting intracranial hemorrhages from Traumatic Brain Injury (TBI)
• Detecting intracranial hemorrhages in juveniles from Mild Head Injury (MHI)
• Delayed medical attention is the biggest reason for mortality in TBI patients
• Preventing any further brain damage
History
• TBI have been told of before recorded history
• Before the 1900s brain injuries were typically fatal (Civil War 70% fatality rate)
• With advances in neuroscience leading into WWI, Austria and Germany created brain rehabilitation centers
• 1970s- CT scans and MRI scans are developed
• 2012- Infrascanner 1000 is FDA approved
• 2013- Infrascanner 2000 is FDA approved
Infrascanner 1000
• Portable hand held 2 piece device• Benefits those immediately• Uses Near-Infrared (NIR) technology• Composed of NIR diode and detectorsend information wirelessly via Bluetoothto the screen • Displays where the patient is hemorrhaging • Rechargeable battery pack
Infrascanner 2000
• Developed following specifications from the Marine Corps.
• Made the two piece Infrascanner into a one piece sensor, processor with display and controls
• Improved durability for warfare
• Ability to use AA batteries as well as the rechargeable battery pack
NIR Technology
• Hemoglobin has unique light absorbing qualities
• Non-invasive
• Does not ionize like CT scans
• Extravascular blood absorbs the light ten fold
• Less light is reflected back, that is where hemorrhaging occurs
Applications
• Emergency room
• ICU
• Military Field Hospitals
• Remote locations
• Sports
• Ambulance services
• Pediatrics
Limitations
• Cannot detect deep or small hemorrhages accurately
• This procedure must be performed before hemoglobin breaksdown
• Thick hair can act as a barrier
• Unit cost is $19,500
Future
• Ability to read deeper and detect smaller hemorrhages
• Cheaper
• More durable
