| contents | The increase in safety and critical systems improved Healthcare. Due to their risk of harm, such systems are subject to stringent guidelines and compliances. These safety measures ensure a seamless experience and mitigate the risk to end-users. Institutions like the Food and Drug Administration and the NHS, respectively, established international standards and competency frameworks to ensure industry compliance with these safety concerns. Medical device manufacturing is mainly concerned with standards. Consequently, these standards now advocate for better human factors considered in user interaction for medical devices. This forces manufacturers to rely on heavy testing and review to cover many of these factors during development. Sadly, many human factor risks will not be caught until proper testing in real life, which might be catastrophic in the case of an ambulatory device like the T34 syringe pump. Therefore, effort in formal methods research may propose new solutions in anticipating these errors in the early stages of development or even reducing their occurrence based on the use of standard generic model. These generically developed models will provide a common framework for safety integration in industry and may potentially be proven using formal verification mathematical proofs. This research uses SPARK Ada's formal verification tool against a behavioural model of the T34 syringe driver. A Generic Infusion Pump model refinement is explored and implemented in SPARK Ada. As a subset of the Ada language, the verification level of the end prototype is evaluated using SPARK. Exploring potential limitations defines the proposed model's implementation liability when considering abstraction and components of User Interface design in SPARK Ada. |
