Device.identifier | |||||||||
Element Id | Device.identifier | ||||||||
Definition | Unique instance identifiers assigned to a device by manufacturers other organizations or owners. | ||||||||
Short Display | Instance identifier | ||||||||
Note | This is a business identifier, not a resource identifier (see discussion) | ||||||||
Cardinality | 0..* | ||||||||
Type | Identifier | ||||||||
Summary | false | ||||||||
Comments | Certain attributes, like serial number and UDI Carrier (the HRF or AIDC barcode string) are not device instance identifiers as they are not consistently able to uniquely identify the instance of a device, thus are not appropriate to be used to value Device.identifier. The barcode string from a barcode present on a device label or package may identify the instance, include names given to the device in local usage, or may identify the type of device. If the identifier identifies the type of device, Device.type element should be used. The identifier is typically valued if the serialNumber or lotNumber is not valued and represents a different type of identifier. However, it is permissible to still include those identifiers in DeviceDefinition.identifier with the appropriate identifier.type. | ||||||||

Device.udiCarrier.carrierAIDC | |||||||||
Element Id | Device.udiCarrier.carrierAIDC | ||||||||
Definition | The full UDI carrier of the Automatic Identification and Data Capture (AIDC) technology representation of the barcode string as printed on the packaging of the device - e.g., a barcode or RFID. Because of limitations on character sets in XML and the need to round-trip JSON data through XML, AIDC Formats SHALL be base64 encoded. | ||||||||

Summary | false | ||||||||
Comments | Necessary to support mandatory requirements for traceability from donor/source to recipient and vice versa, while also satisfying donor anonymity requirements. The element is defined consistently across BiologicallyDerivedProduct, NutritionProduct, and Device. The identifier references an event that links to a single biological entity such as a blood donor, or to multiple biological entities (e.g. when the product is an embryo or a pooled platelet product). A single biologicalSourceEvent identifier may appear on multiple products of many types derived from a single donation event or source extraction. As an example, a single donation event may provide 2 kidneys and a liver for organ transplantation, 2 corneas for eye surgery, heart valves and arterial tissue for cardiovascular surgery, multiple skin grafts, tendons, multiple shaped bone grafts and a large number of bone putty/paste products; and each of them may be assigned to the same biological source event identifier. | ||||||||

Short Display | Serial number assigned by the manufacturer | ||||||||
Cardinality | 0..1 | ||||||||
Type | string | ||||||||
Summary | false | ||||||||
Comments | Alphanumeric Maximum 20. While a serial number is a type of identifier, in the context of devices for which a UDI is required, thus a serial number may be part of the production identifier, it is more informative to have the serial number as a dedicated attribute together with the other UDI production identifier. When the device is not subject to including the UDI (e.g., its presence and exchange is not mandated by local regulatory requirements or specific use case at hand), thus the concept of production identifiers is not relevant as a set, it remains helpful for consistency to still use Device.serialNumber rather than using Device.identifier with an appropriate type. Systems that do not realize an identifier is a serial number may place it in Device.identifier or if the identifier.system is known for the serial number, it may also be populated in the Device.identifier as a globally unique id_. | ||||||||
Device.name | |||||||||
Element Id | Device.name | ||||||||

Cardinality | 0..1 | ||||||||
Type | Identifier | ||||||||
Summary | false | ||||||||
