IEEE 11073 Service-oriented Device Connectivity (SDC)

The IEEE 11073 Service-oriented Device Connectivity (SDC) standard family defines a communication protocol for medical devices that are used in (potentially) critical patient care, such as the operating theater, the intensive care unit, but also in other areas of the hospital. It is part of the ISO / IEEE 11073 family of standards . IEEE 11073 SDC is based on the service-oriented architecture (SOA) paradigm . Therefore, IEEE 11073 SDC differs greatly in parts from the mechanisms of the "classic" ISO / IEEE 11073 standard family.

IEEE 11073 SDC focuses on manufacturer-independent device-to-device communication. The standard family aims at the interoperability of medical device systems and enables multipoint-to-multipoint information exchange. In addition, a basic data exchange between medical devices and the medical information systems is made possible.

With a clear focus on device-to-device communication, IEEE 11073 SDC does not compete with existing standards or standards such as DICOM , HL7 v2 , HL7 FHIR . Rather, these standards complement each other.

The IEEE 11073 SDC standard family consists of the transport standard, ISO / IEEE 11073-20702 (Medical Devices Communication Profile for Web Services), the domain information and service model (ISO / IEEE 11073-10207) and the architecture and binding standard (IEEE 11073 -20701).

development

The standards of the IEEE 11073 SDC family were largely developed in the course of the BMBF- funded research project OR.NET (and some previous projects). The development takes place with the involvement of all stakeholders: medical technology manufacturers, doctors, hospital operators, research, standardization and certification institutions.

The concepts were evaluated technically and clinically. Comprehensive demonstrators with a large number of cross-manufacturer networked medical devices and the complexity of today's operating theaters were presented to the general public, for example in the course of the conhIT trade fairs in Berlin in 2016 and 2017.

The first devices with open networking capability were presented at the MEDICA trade fair 2018 in Düsseldorf. The first approved IEEE 11073 SDC-compatible devices are expected to be on the market in 2019/20.

ISO / IEEE 11073-20702

The standard "IEEE 11073-20702 - Health informatics - Point-of-care medical device communication Part 20702: Medical Devices Communication Profile for Web Services" ("Medical DPWS" or "MDPWS" for short) ensures the basic interoperability between medical devices. MDPWS enable the secure exchange of data in distributed systems and the dynamic finding of network partners. The standard is derived from the OASIS standard Devices Profile for Web Services (DPWS). MDPWS defines extensions and restrictions to meet the security requirements of networked medical devices.

ISO / IEEE 11073-10207

The standard "IEEE 11073-10207 - IEEE Health informatics - Point-of-care medical device communication Part 10207: Domain Information and Service Model for Service-Oriented Point-of-Care Medical Device Communication" was based on the "classic" IEEE 11073-10201 Domain Information Model (DIM) developed. The standard's non-normative name is Basic Integrated Clinical Environment Protocol Specification (BICEPS). The domain information and service model is designed in such a way that it meets the requirements of multipoint-to-multipoint communication.

The domain information model is divided into two parts to describe the medical device in the network: The device description depicts the capabilities of the device. For example, the existing measured values, parameters, alarms, etc. are described, as well as the options for remote control of certain device functionalities. The second part references the description and reflects the current device status, e.g. B. current values. IEEE 11073-10207 thus ensures structural interoperability.

IEEE 11073-20701

The standard "IEEE 11073-20701-2018 - Health informatics - Point-of-care medical device communication - Part 20701: Service-Oriented Medical Device Exchange Architecture and Protocol Binding" describes on the one hand the overarching service-oriented medical device architecture. On the other hand, the interaction (binding) between IEEE 11073-20702 and IEEE 11073-10207 is described, as well as the use of other standards such as Network Time Protocol (NTP) for time synchronization or Differentiated Services (DiffServ) for Quality of Service (QoS) requirements . With the help of terminology standards (such as IEEE 11073-10101), the IEEE 11073 SDC family of standards enables semantic interoperability.

Open source implementations of IEEE 11073 SDC

There are currently three known open source implementations of the IEEE 11073 SDC:

  • openSDC (Java)
  • SDCLib / C (C ++, former name: OSCLib)
  • SDCLib / J (Java, former name: SoftICE)
  • SDCLib / J (Fork) (Java, Fork with the latest features from the former main author)
  • SDCri (SDC Reference Implementation) (Java)
