Extension: Device Instance extension

Official URL: http://hl7.org/fhir/uv/pocd/StructureDefinition/device-instance Version: 0.4.0
Standards status: Draft Maturity Level: 2 Computable Name: DeviceInstance

StructureDefinition that adds an instance number or label to Device or DeviceMetric.

This extension is intended to distinguish device components (VMDs, Channels, Metrics) of the same type. For example, an ICU patient monitor may provide multiple invasive blood pressure or temperature measurements either built-in or as pluggable modules. The Device Instance extension associates measurement hardware with a Device or DeviceMetric resource instance by number (e.g., slot position) or connector label.
