The IEEE 11073 service-oriented device connectivity family of standards defines a communication protocol for point-of-care medical devices. The main purpose is to enable manufacturer-independent medical device-to-device interoperability.. Furthermore, interconnection between medical devices and medical information systems is enabled. However, IEEE 11073 SDC does not compete with established and emerging standards like HL7 v2 or HL7 FHIR. IEEE 11073 SDC is part of the established ISO/IEEE 11073 family of standards. IEEE 11073 SDC is based on the paradigm of a service-oriented architecture. The IEEE 11073 SDC family of standards currently comprises three parts: Core Standards, Participant Key Purpose standards, and Devices Specialisation standards. The Core Standards consist of a transport standard, , called Medical Devices Communication Profile for Web Services, a Domain Information and Service Model, and Architecture and Binding definition. While the three Core standards have been approved and published by the IEEE as well as by ISO, PKIPs and DevSpecs are currently under development. The concepts have been technically and clinically evaluated. Comprehensive demonstrators were shown, for example, at the conhIT exhibitions 2016 and 2017.
IEEE 11073 SDC Core Standards
ISO/IEEE 11073-20702
The standard "ISO/IEEE International Standard for Health informatics - Point-of-care medical device communication - Part 20702: Medical devices communication profile for web services" enables the foundational interoperability between medical devices. This includes the ability of medical devices to exchange data safely in a distributed system and the ability to discover network participants dynamically. MDPWS is derived from the OASIS standard Devices Profile for Web Services. It defines extensions and restrictions to meet safety requirements of medical devices for high acuity environments.
ISO/IEEE 11073-10207
The Standard "ISO/IEEE International Standard - Health informatics--Point-of-care medical device communication - Part 10207: Domain Information and Service Model for Service-Oriented Point-of-Care Medical Device Communication" is derived from the IEEE 11073-10201 Domain Information Model. It is designed to meet the requirements of networked systems of medical devices establishing multipoint-to-multipoint communication. The Domain Information Model defines the capability description of the medical devices as well as the representation of the current state. The Service Model specifies the way in which service consumer can interact with medical devices implementing the role of a service provider. IEEE 11073-10207 enables the structural interoperability between medical devices. The non-normative name is Basic Integrated Clinical Environment Protocol Specification.
ISO/IEC/IEEE 11073-20701
The "ISO/IEC/IEEE International Standard for Health informatics - Device interoperability - Part 20701:Point-of-care medical device communication--Service oriented medical device exchange architecture and protocol binding" defines the allover service-oriented architecture, specifies the binding between IEEE 11073-20702 and IEEE 11073-10207, and specifies the binding to other standards like Network Time Protocol or Differentiated Services for aspects like time synchronization and Quality of Service requirements. Together with the usage of terminology standards, this standard contributes to the semantic interoperability of medical devices.
IEEE 11073-1070X Participant Key Purpose (PKP) Series
PKPs describe process requirements according to the role of a network participant. While P11073-10700 defines the Base PKP with basic requirements for participating providers and consumers, the three additional PKP standards focus on specific functionalities:
Providing and consuming information in terms of metric data,
Providing and consuming alerts, and
Providing and consuming external control functionalities.
PKPs are thus independent from the particular medical devices and their concrete medical use case. However, they mainly restrict the IEEE 11073 SDC Core standards to enable safe and interoperable medical device systems and to facilitate the approval process.
IEEE 11073-1072X Devices Specialisation (DevSpec) Series
In contrast to PKPs, the DevSpecs are standards for particular classes of medical devices. DevSpecs describe the way the devices are modelled in the network representation and define requirements for the interaction of provider and consumer via SDC, if necessary. Currently, the PoCSpec project develops DevSpecs for High-Frequency Surgical Equipment, endoscopic camera and light source, insufflator, and medical suction and irrigation pump. Modules that can be used by different types of device are defined in the so-called Module Specifications.
