人们越来越需要利用医疗设备的网络连接和互操作性来提高患者安全性和医疗服务的有效性。然而，如果设计不当，通过网络集成医疗设备可能会显着增加系统的复杂性，并使系统更容易出现潜在错误，从而危及患者安全。该系统必须经过设计和验证，以保证在面临网络故障等潜在问题时患者的安全和医疗服务的有效性。在本文中，我们提出了以器官为中心的分层控制架构作为一种可行的解决方案，可以降低系统设计和验证的复杂性。在我们的方法中，医疗器械根据器官特异性人体生理学分组。每个集群捕获医疗设备交互产生的常见模式，并在网络故障期间成为可生存的半自治单元。此外，安全验证和运行时执行可以沿着以器官为中心的分层控制结构模块化。我们展示了Simulink的基于模型的开发框架下所提出的方法的可行性。气道激光手术的简化方案被用作案例研究。
There are growing demands to leverage network connectivity and interoperability of medical devices in order to improve patient safety and the effectiveness of medical services. However, if not properly designed, the integration of medical devices through networking could significantly increase the complexity of the system and make the system more vulnerable to potential errors, jeopardizing patient safety. The system must be designed and verified to guarantee the safety of patients and the effectiveness of medical services in the face of potential problems such as network failures. In this paper, we proposeorgan-centric hierarchical control architectureas a viable solution that reduces the complexity in system design and verification. In our approach, medical devices are grouped into clusters according to organ-specific human physiology. Each cluster captures common patterns arising out of medical device interactions and becomes a survivable semiautonomous unit during network failures. Further, safety verification and runtime enforcement can be modularized along organ-centric hierarchical control structure. We show the feasibility of the proposed approach under Simulink's model-based development framework. A simplified scenario for airway laser surgery is used as a case study.
