Overview
ISO/IEEE 11073-30200:2004 defines a cable-connected transport profile for point-of-care medical device communication. It specifies an IrDA-based local area network (LAN) transport and physical layer tailored for bedside, patient-connected devices. The profile is particularly targeted at legacy devices-equipment already deployed in clinical settings or in production-enabling retrofit-friendly connectivity while remaining suitable for new device designs.
Key topics and technical requirements
- Transport & physical layer: Specifies a connection-oriented cable LAN using communications services and protocols consistent with the Infrared Data Association (IrDA), adapted for medical device use.
- Data link layer: Defines framing (e.g., IrLAP frames), procedure models, and minimum data link layer requirements to support reliable bedside communications.
- Network layer overview: Aligns transport behavior with upper-layer ISO/IEEE 11073 profiles for medical device information exchange.
- Optimizations for bedside devices: Protocol choices and parameterizations are optimized for patient-connected devices where real-time, low-latency, and reliable transfer of vital signs and device operational data are critical.
- Interoperability and MIB/SNTP: Keywords in the standard include MIB (Management Information Base) and SNTP (Simple Network Time Protocol) - indicating support for device management and time synchronization needs (as referenced in the standard’s keywords).
- Design constraints: Emphasis on compatibility with legacy hardware and software, use of widely available vendor components, and leveraging mainstream computer-industry communications technology to minimize cost and implementation risk.
Applications
- Retrofitting bedside devices (patient monitors, ventilators, infusion pumps, ECG devices) to provide standardized electronic data capture and integration with clinical IT systems.
- Enabling plug-and-play, real-time interoperability at point-of-care for vital signs acquisition and device telemetry.
- Supporting clinical environments that require time-correlated multi-device data for monitoring, alarms, and archiving.
Who should use this standard
- Device systems engineers and firmware architects integrating networking into medical devices, especially when updating or connecting legacy equipment.
- Clinical informatics and biomedical engineering teams planning device connectivity strategies in acute and continuing care settings.
- Vendors and integrators seeking compatibility with the ISO/IEEE 11073 family and IEEE 1073 objectives for medical device communications.
