ECMO Circuit Pressure Alarm PROJECT PROPOSAL
University of Pittsburgh Senior Design - BioE1160 ECMO Circuit Pressure Alarm PROJECT PROPOSAL Desiree Bonadonna Apryle Craig Laura Gilmour ECMOre, Uninc.
2
Overview ECMO Pressure Alarm Pre-Oxygenator Post-Oxygenator
Post-Heat Exchanger Audible and Visual Alarms Make healthcare workers aware of high/low pressures Dangers of high/low pressures Healthcare Workers Perfusionists ECMO Technicians Physicians Nurses Redesign Analog Digital Programmable Audible Alarm Add additional pressure indicator (post heat-exchanger)
3
Project Goals Develop digital pressure alarm system
Simulink model Build model Submission for FDA approval Milestones Current technology summary Re-assess project goals Redesign Add programmable inputs Add alarm Add sound Deliverable
4
Features & Benefits Three inputs
Monitor pressure pre- and post-oxygenator Monitor pressure pre- and post-heat exchanger Digital System Reduce interpretation errors Clear and easy to understand Consistency Three read-outs Clear display of each pressure Three pressures can be monitored and compared at same time
5
Features & Benefits Programmable range
Adjust high and low alarm range per patient basis Allows for variable sensitivity of system Audible and Visual Alarms Alert staff by audible alarm Notify particular pressure deviance by visual alarm
6
Description: Circuit Modification
7
Description: Device Circuitry
8
Design Alternatives Types of Displays Number of Audible Alarms
Number of Visual Alarms Alarm independence/convenience
9
Competitive Analysis Current Medically approved devices No audible
Analog Difficult to read Not clearly labeled No audible No visual alarm Non-approved devices Digital with visual alarm
10
ECMOre Design weaknesses
Competitive Analysis ECMOre Design weaknesses More expensive than analog More tubing in an already cluttered space Increased training time/expenses
