ARMxy BL450-Based Medical Device Interconnection & Remote O&M Solution

I. Executive Summary

II. Analysis of Core Industry Pain Points

1. Severe Data Silos

   Different brands of medical devices including MRI, ECG machines and blood analyzers operate independently, and traditional management systems lack unified data aggregation capabilities. This makes cross-device data analysis and clinical decision support impossible, and even within the same department, device data cannot be shared in real time, which affects diagnosis efficiency.
2. Protocol Incompatibility

   Medical devices adopt proprietary or industry-specific protocols such as DICOM, HL7 and IEEE 11073, while traditional gateways lack flexible protocol adaptation capabilities. This hinders cross-device and cross-department data interconnection, and also prevents connection to hospital-level SCADA or IoT cloud platforms.
3. Slow Fault Response

   Medical device failures rely on on-site diagnosis by manufacturers, resulting in prolonged downtime, which can even reach several hours for specialized equipment, directly affecting clinical treatment and emergency rescue processes.
4. Data Privacy Risks

   Medical device data involves core patient privacy. Traditional plaintext or weak encryption transmission methods cannot balance data sharing and security protection, and are prone to compliance risks in cross-institutional data collaboration.
5. Poor Adaptability to Complex Environments

   Hospital equipment rooms have complex electromagnetic environments due to the presence of multiple high-power medical devices, and some mobile medical scenarios such as emergency vehicles face extreme temperature or vibration challenges, while traditional gateways lack industrial-grade reliability guarantees.
