Technical architecture for bridging low-level point-of-care medical serial protocols into FHIR REST APIs and WebSockets.
Medical device telemetry encompasses serial RS-232, USB HID, and BLE packets with proprietary binary formats. The gateway utilizes deterministic state machines to decode raw packets into IEEE 11073 Domain Information Model (DIM) objects.
Decoded DIM objects are mapped to FHIR Observation resources with standard LOINC and SNOMED-CT coding. Streaming WebSockets provide real-time updates to nursing stations while durable Kafka topics archive waveforms for clinical audit.
Under IEC 62304 Class B/C guidelines, the communication bridge must run in an isolated process with strict resource quotas, ensuring that network packet floods cannot crash core physiological monitoring routines.
