Problem Patient IV injection and blood sampling => multiple needle sticks Excessive waste, biohazard Psychological damage, trauma Time spent acquiring, lab time – for each stick Many needle sticks, increased infection risk

Solution? Combined needle design, multi-lumen Multifunctional: sensors, blood drawing, injection Valves & Ports Multi-lumen catheter Blood draw lumen IV administration lumen X Sensor access orifices

Plan of Attack Computational Model: CFD software Physical Model: testing, rough design

Proposed Schedule December: lit review, begin comp model January: comp modeling, begin physical testing with rough needle model February – March: refine design parameters, continue testing April: finish design, prepare presentation

Needs Dr. Collins: In-house CFD Software, setup accounts Dr. Giorgio: building test system, reducing cost as mentioned on proposal More conference calls with MedTG Supplies to order: non-communicating double-lumen needles
