SDC Standards Family
IEEE 11073 Service-oriented Device Connectivity (SDC) is a family of standards. This family has three major parts: The Core Standards, the Participant Key Purposes (PKPs), and the Device Specializations (DevSpecs).
The Core Standards define the transport mechanism (ISO/IEEE 11073-20702) and the domain information and service model (ISO/IEEE 11073-10207). The third standard, ISO/IEEE 11073-20701, describes the architecture and the binding of the two previously mentioned standards. The blue parts of the figure display the Core Standards.
While nomenclature standards are mostly not direct part of SDC, they are crucial to achieve semantic interoperability. Currently, the IEEE 11073-1010x nomenclature series is used. However, other sophisticated systems like SNOMED CT or LOINC are possible.
The PKP standards (see green part of the figure) define technical, process, and documentation requirements to ensure safe, secure, and effective interconnection between medical devices of different manufacturers. They define the different responsibilities of the network participants or the corresponding manufacturers, respectively, in a system where different medical devices provide contributions to an overarching system function. They allow for a test-to-interface concept and will enable the approval of interoperable medical devices that do not know their interconnection partners when being developed. Therefore, the Base PKP defines common requirements, while the Metric PKP, Alert PKP, and External Control PKP are specific for their use cases.
The third part of SDC is depicted in yellow. While Core Standards and PKPs are generic, the DevSpecs are specific for a particular class of medical devices. For example, there are DevSpecs for high frequency equipment, endoscopic camera and light source, insufflator, and suction/irrigation pumps under development. Additionally, there is a special standard, called Modular Specifications (ModSpecs, IEEE P11073-10720), that defines parts that can be used by different DevSpec, e.g., user interaction items, like foot switches.
The SDC family of standards is complemented by the IHE Service-oriented Device Point-of-care Interoperability (SDPi) profile. In the spirit of the IHE, use cases are defined and the standards are tailored.
