THE APPLICATION OF HUMAN ENGINEERING TO THE SAFETY DESIGN OF MEDICAL APPARATUS BASED ON SYSTEM APPROACH (II. Human Engineering to the Safety Design of Medical X-Ray System)

Abstract

The concept of applying Human Engineering to the safety design of medical appatatuses and systems is discussed. It has been required to apply the safety engineering to medicine in order to meet the requirements from sophisticated man-machine systematizations in a hospital. The basic elements of the systems engineering in terms of safety design include 1) to treat the objects as a total system, 2) to apply the most appropriate measures with limited resources. From this point of view it is useful to consider the system's lifecycle, i.e., planning-designing-producing-installing-managing-replacing cycle. The most appropriate safety measures have to be applied to each stage of the cycle. Human Engineering based measures such as appropriate man-machine interface design are the key points to achieve the concept.
