Data Profile for This Category
Core data sources for medical devices include registration and filing information publicly available from the National Medical Products Administration, official product manuals, clinical trial reports, and compliant marketing materials. Registration certificate information is updated regularly alongside approval progress. Manuals are adjusted per compliance requirements. Clinical data is updated periodically via post-market research.
In terms of document structure, registration certificate information consists of structured fields. Manuals are long text with chapter divisions. Clinical data is mostly multi-page PDFs or structured tables. Marketing materials are mostly rich text formats.
Fields and units include registration certificate number, scope of application, rated power, detection accuracy, registration validity period, and some devices also have calibration cycle parameters.
Constraints Imposed on Workflow Orchestration
Medical device data comes from multiple sources with significant format differences, creating multiple constraints for workflow orchestration.
Structured registration and filing information requires separate field extraction node configuration to avoid conflicting parsing with long-text manuals. Long documents such as clinical trial reports require segment parsing rules to avoid exceeding context limits from processing too much content at once. Rich text marketing materials require format parsing configuration to prevent loss of compliant display elements such as images and tables.
The multi-source data aggregation link must add parameter verification steps to ensure parameter alignment for the same product. It must also configure compliance interception rules to filter product data that has not completed qualification verification.
How to Configure the Workflow
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_MAX_SIZE | 200 MB | Medical device manuals and clinical report files typically do not exceed 150 MB, with reasonable buffer space reserved |
Segment Length | 800–1200 characters | Balances context association and processing efficiency for long-text parsing, and adapts to the chapter length of most medical device documents |
HTTP_REQUEST_CONTENT_TYPE | multipart/form-data | Medical device marketing materials often include attachments such as images and PDFs, so this format is required to transfer file parameters |
WORKFLOW_DATA_VALIDATE_RULES | ["注册证编号校验", "资质有效期校验"] | Medical device marketing must comply with regulatory requirements, and these rules can intercept product data that fails qualification verification |
UPLOAD_FILE_ALLOW_EXT | ["pdf", "docx", "jpg", "png"] | Covers common file formats for medical device registration certificates, manuals, and marketing materials |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Adapts to the parsing duration of large clinical reports and avoids timeout interruptions |
The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material form, data volume, and business rules. Specific issues require individual analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Configuration Mistakes
- Phenomenon: The workflow generates content normally in the run preview page, but returns empty results when called on the official chat page. Cause: The workflow's input parameters are not bound to the user request parameters of the chat page, or the chat context transfer rules are not configured.
- Phenomenon: When configuring a form-data type HTTP request, medical device manual PDF files cannot be uploaded correctly. Cause: The request parameter type is not set to file stream, or the output of the file parsing node in the workflow is not bound as the parameter value.
- Phenomenon: An error "Load file error" is prompted when uploading a medical device clinical report file. Cause: The file size exceeds the
PARSE_FILE_MAX_SIZEconfiguration threshold, or the file format is not within the allowed range ofUPLOAD_FILE_ALLOW_EXT.
How to Confirm Proper Configuration
- Verify the parameter configuration of the workflow input node to ensure it can receive medical device product identification parameters from the chat page.
- Validate the settings of the file parsing node to confirm they match the format and parsing requirements of medical device documents.
- Run a workflow preview test, upload registration certificate, manual, and clinical report files for the corresponding category, and confirm the parsing results are complete.
- Trigger the compliance verification logic to confirm that product data that fails qualification verification is intercepted.
