Under the supervision of:

Dr. Eng. FadelAlakwa.

2010-2011

slide2

AAMI Standard:

This Association for the Advancement of Medical Instrumentation (AAMI) standard implies a consensus of those substantially concerned with its scope and provisions. The existence of an AAMI standard does not in any respect preclude anyone, whether they have approved the standard or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standard. AAMI standards are subject to periodicreview, and users are cautioned to obtain the latest editions.

slide3

AAMI Human Factors Engineering Committee:

  • This Committee that considered for the design of a particular medical device with a user interface have a fitting must be derived from two standpoints:
  • human factors design process.
  • human factors design principles.
slide4
