Capstone Design – Designing Smarter Infusion Pumps: Closing the Loop on Patient Safety
Large "square" interface intended for a touch-screen-based smart pump. Contains simple instructions to facilitate QR code scanning.
Mobile scanning device provides simple instructions and collects information from scanned QR codes.
Medication labels are QR coded. Border of medication label should match stripe on tubing.
Label is double-sided to separate information intended for nurses and pharmacists to reduce clutter and false confirmation risk.
Back side of label
When information collected from QR codes doesn't match up, the process is stopped so that no unsafe workarounds can take place.
If all information scanned is correct, it communicates parameters to the pump, and the clinician can review what has been scanned.
Running screen (blue bar should match blue label)
Epidural medication has a yellow running screen and should connect to yellow labels and tubing

This Capstone Design project is a collaborative effort with M. Gavin, R. Afante, and M. Lee, in conjunction with the Interactive Media Lab at the University of Toronto and the Centre for Global eHealth Innovation at University Health Network.
The objective is to design a new system of integrated workflows and software technologies to address the limitations imposed by drug library software present in infusion pumps, the reliance of barcode medication administation systems on wireless technology, and overall reliance on human vigilance, in a clinical setting which often subjects health care providers to high cognitive workloads. Over the span of 8 months, the team managed and executed the project, culminating with the construction and formative usability testing of a low-fidelity prototype. Further iterations will incorporate design changes to address usability issues from this version.
