Vysio: Device-to-EMR Platform Integrating Wearable Data via FHIR and HL7v2
Vysio — Device-to-EMR platform - Tech in Motion
Summary
Vysio has developed an end-to-end platform that acquires data from wearable hemodynamic monitors via a BLE gateway, standardizes it using FHIR R4, and integrates it into hospital EMRs using standards like HL7v2. This enables the automatic linkage of real-time vital sign information to multiple major EMR systems.
Details
The platform starts by acquiring biometric data (such as HbT and StO₂) from a wearable device via a BLE 5.0 gateway, which streams readings into a Next.js dashboard for real-time visualization. The data is then standardized as FHIR Observations and processed through an event-driven subscription mechanism orchestrated by n8n. Finally, Mirth Connect translates the data from FHIR to HL7v2 ORU^R01 format before sending it to major EMR systems like Epic or Oracle Health (Cerner). This entire process operates in a secure, self-hosted environment utilizing technologies such as HashiCorp Vault and Tailscale. The system ensures authentication and integration via SMART on FHIR. By handling everything from remote patient monitoring data collection and clinical alerting to standardized information delivery across multiple legacy and modern EMRs, this technology offers high potential for implementation in Japanese healthcare settings.
