Modelling bio-compatible and bio-integrative medical devices

International audienceDeveloping and producing medical devices and healthcare systems is a crucial issue, both for the economy and for providing safe advances in healthcare delivery. We propose a taxonomy of medical human machine systems and we define classes of healthcare applications for identifying a number of approaches and to overcome difficulties of bio-compatibility and bio-integration. Our aim is to demonstrate how medical devices design, and more generally human-machine system concepts and epistemology, depend on our skills to think and conceptualize generally human system integration. We claim that it is necessary to reclaim these concepts for ensuring correct by construction medical devices bio-compatibility and biointegrative properties from the early stage of the design process

From symbolic constraint automata to Promela

In this paper, we study a subclass of constraint automata with local variables. The fragment denotes an executable subset of constraint automata for which synchronization and data constraints are expressed in an imperative guarded command style, instead of a denotational style as in the coordination language Reo. To demonstrate the executability property, we provide a translation scheme from symbolic constraint automata to Promela, the language of the model checker Spin. As a proof of concept, we model in Reo a software defined network circuit, and use the Spin model checker to verify that our model satisfies some temporal properties. (C) 2022 The Author(s).
