To represent medical device observations in a format that is consumable by clinical software, standards like HL7v3 and ISO/IEEE 11073 should be used jointly. This is demonstrated in a project with Dräger Medical GmbH focusing on their Patient Data Management System (PDMS) in intensive care, called Integrated Care Manager (ICM). Patient and device data of interest should be mapped to suitable formats to enable data exchange and decision support. Instead of mapping device data to target formats bilaterally we use a generic HL7v3 Refined Message Information Model (RMIM) with device specific parts adapted to ISO/IEEE 11073 DIM. The generality of the underlying model (based on Yuksel et al. [1]) allows the flexible inclusion of IEEE 11073 conformant device models of interest on the one hand and the generation of needed artifacts for secondary usages on the other hand, e.g. HL7 V2 messages, HL7 CDA documents like the Personal Health Monitoring Report (PHMR) or web services. Hence, once the medical device data are obtained in the RMIM format, it can quite easily be transformed into HL7-based standard interfaces through XSL transformations because these interfaces all have their building blocks from the same RIM. From there data can be accessed uniformly, e.g. as needed by Dräger´s decision support system SmartCare [2] for automated control and optimization of weaning from mechanical ventilation.
为了以临床软件可使用的格式呈现医疗设备观察结果，应联合使用HL7v3和ISO/IEEE 11073等标准。这在与德尔格医疗有限公司（Dräger Medical GmbH）合作的一个项目中得到了证明，该项目专注于其重症监护中的患者数据管理系统（PDMS），即综合护理管理器（ICM）。感兴趣的患者和设备数据应映射到合适的格式，以实现数据交换和决策支持。我们不是将设备数据双边映射到目标格式，而是使用通用的HL7v3细化消息信息模型（RMIM），并将特定于设备的部分适配到ISO/IEEE 11073设备信息模型（DIM）。基础模型的通用性（基于Yuksel等人[1]）一方面允许灵活纳入感兴趣的符合IEEE 11073的设备模型，另一方面允许生成用于二次使用所需的工件，例如HL7 V2消息、诸如个人健康监测报告（PHMR）之类的HL7临床文档架构（CDA）文档或网络服务。因此，一旦以RMIM格式获得医疗设备数据，就可以通过XSL转换相当容易地将其转换为基于HL7的标准接口，因为这些接口都具有来自相同参考信息模型（RIM）的构建块。从那里可以统一访问数据，例如根据德尔格的决策支持系统SmartCare [2]的需要，用于机械通气撤机的自动控制和优化。
