DeviceComponent Profiles
Scope and Usage
These DeviceComponent profiles are part of the Point-of-Care Device General Implementation Guide. A set of DeviceComponent and DeviceMetric resources represent the physical or logical structure of a medical device in a containment hierarchy.
A compliant device is represented by multiple DeviceComponent resources according to the MDS, VMD, and Channel DeviceComponent profiles. A top-level MDS DeviceComponent makes the root node of the tree structure. There shall be one or more VMD DeviceComponents at the VMD level, and one or more Channel DeviceComponents per VMD at the Channel level. The profiles define the following rules:
DeviceComponent.typeshall have a coding from the ISO/IEEE 11073 MDC device nomenclature. The Rosetta Terminology Mapping Management System (RTMMS) lists available codes.DeviceComponent.type.codingallows additional coding from other code systems.DeviceComponent.sourceshall be present and refer to a Device resource according to the PoC Device profile.DeviceComponent.parentis a reference to the next upper level DeviceComponent resource. For Channel DeviceComponent, it shall be present and refer to a VMD DeviceComponent. For VMD DeviceComponent, it shall be present and refer to a MDS DeviceComponent. For MDS DeviceComponent it's optional and may refer to another MDS DeviceComponent as a composite MDS.- If multiple instances of the same VMD or Channel type exist, the Instance extension allows to define a sequence.
- To assign a common color representation for all metrics in a Channel, the Color extension can be used. It gets a code from the DeviceMetricColor value set.
