Improving IV Infusion

: RESEARCH, INNOVATION AND ENTREPRENEURSHIP AT THE UNIVERSITY OF WAIKATO SPRING 2012 www.waikato.ac.nz Improving IV infusion THE humble drip has given way to hi-tech infusion pumps in hospitals in New Zealand and around the world – but software glitches and issues around the usability of the new devices have raised questions about safety. “Hospitals don’t let the manuals for these devices get anywhere near their staff,” says Dr Judy Bowen, an expert on the design of safety-critical interactive systems in the Department of Computer Science at the University of Waikato. “The Waikato District Health Board develops some of its own training materials and uses those developed by pump distributors – and when you look at how these devices work, you can understand why.” Dr Bowen and Professor Steve Reeves of the Formal Methods Group are working with the DHB’s Biomedical Division at Waikato Hospital to “reverse engineer” some of the pumps used in the hospital. Dr Bowen is focusing on the user interface by mathematically modelling the instructions in the manual and seeing what divergences there are with the device’s actual behaviour. “We’ve found some interesting and unexpected behaviours,” she says. “For example, when you hit PUMP PRIMING: Dr Judy Bowen and Professor Steve Reeves say medical infusion pumps are a prime candidate for formal software Continued Page 2 modelling techniques to improve safety. Waikato to Washington: SIFE students take on the world A GROUP of Waikato University students is off around waterways to reduce nitrogen leaching to Washington DC in September to represent into the water, together with research into the New Zealand at this year’s SIFE (Students In Free eradication of the pest koi carp.
