What the Data for This Category Looks Like
Medical device research report data mainly comes from the National Medical Products Administration public database, third-party medical consulting firm industry research materials, and official disclosure documents of medical device manufacturers. Update rhythm adjusts with regulatory policy changes, new product launches, and industry quarterly inventory. There is no fixed cycle. Most documents are in multi-page PDF format. Their structure includes fields such as report title, issuing institution, release date, applicable device classification, core technical indicators, clinical application data, and compliance status. Units of core indicators include professional medical device measurement units such as μm, units, times/minute, pieces, and others.
Constraints on Deployment and Upgrade
Decentralized data sources require configuring multi-source data connection permission rules during deployment to avoid cross-source data conflicts. No fixed update cycle requires configuring incremental synchronization trigger mechanisms during deployment. These mechanisms can be triggered via event listening or scheduled tasks. The document structure contains a large number of professional medical terms and exclusive fields. During the upgrade phase, parsing templates and field extraction rules need to be readapted. This ensures that core information such as registration certificate numbers and applicable departments is correctly identified. Multi-unit indicator fields require configuring normalization conversion rules during deployment. This avoids unit mismatch issues during retrieval.
Configuration Settings
| Configuration Key | Recommended Value | Rationale |
|---|---|---|
PARSE_FILE_TIMEOUT_SECONDS | 120 seconds | Medical device research reports often contain multi-page charts and dense text, to avoid parsing timeouts |
UPLOAD_FILE_MAX_SIZE | 500 MB | The PDF size of individual medical device research reports is generally larger than that of general documents, so upload limits need to be relaxed |
maxContext | 8000 characters | Core technical and compliance information of medical device research reports is concentrated in the front-middle section, requiring sufficient context for recall |
Recall Count | Top 8 entries | Relevant information of medical device research reports is often scattered across different chapters, requiring sufficient quantity of recall results to match retrieval needs |
Similarity Threshold | 0.75 | Medical device terms are highly professional, to filter irrelevant reports with low matching degrees |
Reranked Return Count | Top 5 entries | Final retrieval results need to streamline core matching items to avoid information overload |
The parameter values provided on this page are common starting points for configuration. Actual values are affected by material form, data volume and business rules. Specific issues require specific analysis, and it is recommended to test on your own samples before finalizing settings.
Three Common Errors
- Phenomenon: After upgrading to version v4.13.1, the management backend still displays the version identifier of v4.9.2. Cause: Hard-coded parameters for built-in version verification were modified during secondary development, and version configuration items were not updated synchronously.
- Phenomenon: Outputs from multiple variable update nodes cannot be aggregated into a single AI reply, and workflow execution reports an error. Cause: Field mapping rules for variable aggregation were not configured, resulting in failure to uniformly integrate multi-dimensional data from medical device research reports.
- Phenomenon: The deployed MongoDB 5.0.18 version triggers a security vulnerability scan alert. Cause: MongoDB was not upgraded to the security patch version released by the official, and access permission restrictions for the data source were not configured.
How to Confirm Proper Configuration
- Upload the largest individual medical device research report, confirm that the parsing task has no timeout errors, and the returned parsed text contains exclusive fields such as registration certificate numbers and applicable departments.
- Initiate a retrieval request containing professional medical device terms, verify that the matching degree of returned results meets the preset similarity threshold requirements.
- Execute the version upgrade script, log in to the management backend and confirm that the version identifier matches the target upgrade version.
- Trigger an incremental synchronization task, check whether newly added manufacturer new product research reports are automatically indexed and can be retrieved.
