SaMDSystem: 分布式 SaMD 系统设计、硬实时辅助诊断与 HL7 数据流水线

SaMDSystem 构筑大型医疗器械系统工程架构、实时高并发消息中间件以及高容错辅助诊断管道，将异构医学影像模态（CT/MRI/超声）、实时生理体征传感器与临床决策算法无缝整合为统一的合规认证医疗软件系统。

SaMDSystem Distributed Systems Architecture & Medical Pipeline Topology

Real-time diagnostic broker, HL7/DICOM transformer, and distributed consensus logger

Central System: Diagnostic Systems Router - Real-Time Medical Broker

Clinical IoMT Nodes

  • HL7 CDA / v2 Listener
  • DICOM Worklist Manager
  • Distributed Event Broker
  • Diagnostic Pipeline Runner
  • System Health Supervisor

Architectural Layers & Regulatory Standards

  • Hospital Protocol Ingestion Layer (HL7 v2.x MLLP / DICOM DIMSE / HL7 CDA): Interfacing with legacy hospital telemetry, laboratory information systems (LIS), and imaging devices.
  • Real-Time Clinical Event Bus (Apache Kafka / NATS with Exactly-Once Semantics): Streaming physiological alarms, diagnostic orders, and clinical events with guaranteed delivery.
  • Algorithmic Orchestration Grid (Kubernetes Microservices / Ray Distributed Inference): Scheduling complex multi-stage diagnostic pipelines across CPU/GPU compute clusters.
  • Continuous System Safety Supervision (ISO 14971 Real-Time Hazard Watchdog): Detecting pipeline delays, corrupted data packets, or algorithm timeouts, triggering safe fallback states.

Key Metrics: < 15 ms (Internal Event Bus Latency) | 100% (Guaranteed Delivery (EOS)) | Class B/C (System Safety Classification) | Zero Loss (Patient Telemetry Retention)
