Using Heuristic Analysis to support Usability Evaluation of a low risk medical device under development process

New technologies in the healthcare area have increased the possibilities to diagnose and treat the patients but also have added complexity and associated risks by use errors and users dissatisfaction during the use of complex machines. This paper deals with a new medical device under development in Brazil. The device is classified in the country as a low risk, but the device is intended to give comfort and to prevent futures problems to the patient under its use. The manufacture wants to evaluate the usability of the device to provide user satisfaction and efficient use of it. The heuristic analysis was the method chosen to evaluate the device, early as a prototype, in order to identify problems in the developing interface. The analysis was done by six specialists in Human Factor Engineering & Usability Lab in Federal University of Itajuba. We conclude that the heuristic evaluation was appropriate to evaluate the equipment in question, since helped identify relevant points that should be considered by the manufacturer to meet your customer and contribute with safety and efficiency in use.
