The Electrosurgery Unit Tester (ESU Tester) for developing countries
Electrosurgery is a way to perform medical operations, with the ability to cut tissue or coagulate it to prevent blood during surgery. Discarded electrosurgery units (ESUs) can make it to the developing world through the work of charities, non-governmental organizations and other groups. Unfortunately, much of it is not fully functional. This ESU tester costs roughly 1/100 the price of an ESU analyzer used in developed countries, but the tester still provides the essential function: measuring the power output of the ESU. This information is useful to hospital technicians as they diagnose medical equipment so they know what repairs or preventative maintenance need to be performed.Full list of winners at Fast Company.
