overview
Overview
  • There is no means of rapidly cooling pediatric and neonatal ECMO patients.
  • Cooling offers a way to provide neurological protection for the patient.
  • Solution: A cooling unit that will work in conjunction with pediatric and neonatal ECMO circuits
  • Current Design Possibilities:
    • Cooling block
    • Cooling sleeve
next semester project goals
Next Semester Project Goals
  • High-level timing goals:
    • January – choose design and start

modeling

    • February – complete computer modeling

& analysis

    • March – research means of building

cooling unit

features benefits
Features & Benefits
  • Features:
    • Accurate and rapid cooling
      • Prevention of neurological damage and patient safety
    • Patient temperature sensors
      • Ensure proper cooling
  • Benefits:
    • Inducing hypothermia when desirable
    • Integration into ECMO circuit
      • Limits amount of new equipment and pick and choose when to use it
competitive analysis
