Model-driven tools for medical device selection

Abstract

Safety-critical medical devices are used in hospitals and medical facilities throughout the world, and are relied upon to function correctly and be usable so as not to endanger patients. While such devices are often designed for specific use-cases in specific locations, in reality they may be used in a much wider range of contexts. In addition, the proliferation of these devices within a single environment means that selecting the most appropriate device for a specific task is not always straightforward. In this paper, we consider ways of modelling the context of use of medical devices and how such models may be used to support tools which provide medical personnel with assistance in making decisions about which devices to use in which circumstances.

Reasoning About Interactive Systems in Dynamic Situations of Use

“…There are many different ways of describing the models and reasoning about them (Bowen et al, 2014). Here, we describe the attributes and properties as sets to show the effects of the relations, but we can practically implement the reasoning described in several different ways, including following the ontology approach used previously.…”

“…7: Overview of tool structure Such a tool must be tailored to the specific end-user and their requirements -for example a local government emergency management body. We have previously developed such a tool for use with our medical domain example (Bowen et al, 2014) and suggest using the same approach to develop a tool for the emergency management scenarios. Figure 8 shows a proposed prototype interface for such a tool.…”

“…Subsequently we incorporated the reasoning into a tool which provides the relevant information (i.e. the answers to the questions listed above) in a palatable form for users (Bowen et al, 2014).…”
