What data for this category looks like
Data for medical device intelligent due diligence reports comes primarily from the National Medical Products Administration Medical Device Registration Database, manufacturer qualification documents, publicly available clinical trial reports, and adverse event records released by regulatory authorities. There are two update schedules: registration certificate documents are updated every 5 years upon renewal. Adverse event records are updated in real time alongside regulatory notifications. The document structure includes modules such as registration certificate number, manufacturer name, intended use, technical parameters, adverse event record entries, and more. Technical parameter fields often include specialized units such as mm, μm, kV. Some documents include high-definition image attachments.
What constraints these characteristics impose on HTTP interfaces and external systems
Multi-source and heterogeneous document types require HTTP interfaces to support parsing and field extraction for multiple formats including PDF, DOC, and CSV. Using only a single format may cause parsing failures. Technical parameter fields with specialized units require interfaces to retain original units while supporting parameter configuration for standardized unit conversion. This adapts to display requirements of different third-party systems. Differences in update schedules require interfaces to support incremental pull modes based on update timestamps. This reduces bandwidth and computing resource consumption caused by full pulls. Fields with strict validation requirements such as registration certificate expiration dates require interfaces to return field validity check results. This assists downstream systems with data auditing.
How to set configurations
| Configuration Item | Recommended Setting | Rationale |
|---|---|---|
PARSE_FILE_MAX_SIZE | 200 MB | Medical device due diligence reports often include high-definition image attachments. Setting a single file maximum size no lower than 200 MB covers most registration certificate scan files |
SYNC_INTERVAL | 86400 seconds | Medical device registration certificate update cycles are mostly annual. Daily synchronization covers regular update requirements |
FIELD_UNIT_STANDARD | Retain original units + standardized conversion | Medical device technical parameters must retain original markings while supporting unified unit display for downstream systems |
API_RESPONSE_FIELDS | registration certificate number,manufacturer name,intended use,technical parameters,adverse event records | Core due diligence fields must be returned accurately to avoid redundant data occupying bandwidth |
STREAM_OUTPUT_ENABLE | Enabled | Streaming output during long document parsing reduces front-end waiting time, adapting to real-time display requirements of third-party systems |
The parameter values provided on this page are general recommendations used as a starting point for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require case-by-case analysis. It is recommended to test on your own samples before finalizing settings.
Three common configuration errors
- Knowledge base image links returned by the interface fail to load normally in third-party systems, with status code 403 or invalid links. The cause is that the
API_PUBLIC_ACCESSparameter is not configured, and only intranet access permissions are enabled. This prevents external systems from pulling image resources. - The technical parameter field returned by the interface is empty. The cause is that the
technical parametersfield is not configured inAPI_RESPONSE_FIELDS, or the technical parameter extraction switch for medical device documents is not enabled during parsing. - Interface calls time out, with status code 504. The cause is that the
PARSE_FILE_TIMEOUT_SECONDSparameter is not adjusted. Parsing high-definition images in medical device reports exceeds the default threshold.
How to confirm configurations are correct
- Call the test interface, verify that the returned fields exactly match the preconfigured
API_RESPONSE_FIELDS, and that technical parameter fields include original units. - Upload a medical device registration certificate scan, trigger parsing, and check that the streaming data returned by the interface is returned in segments.
- Configure an incremental synchronization task, modify the update time of a test data entry, call the synchronization interface, and confirm that only the modified entry is returned.
- Access the image link returned by the interface, confirm that it loads normally in third-party systems, with no permission-related errors.
