HTTP Interfaces and External Systems for Medical Device

What the data for this category looks like

Medical device research report data mainly comes from professional pharmaceutical industry databases, public registration information from the National Medical Products Administration, securities firm pharmaceutical industry research reports, and official technical documents from medical device manufacturers. There are two update cycles: new approved medical device research reports update in real time alongside regulatory approval progress. Regular industry research reports are released quarterly, semi-annually, or via temporary announcements.

Document structures typically include fields such as device classification, registration certificate number, core technical parameters, clinical application scenarios, and compliance requirements. Some documents include high-resolution image charts. Units are mostly international standard units; for example, radiation dose uses mGy, and pressure uses kPa.

What constraints do these characteristics impose on HTTP interfaces and external systems?

The unique characteristics of medical device research reports impose multiple constraints on HTTP interfaces and external systems. First, the registration certificate number is the core unique identifier. Interfaces must support precise retrieval using this field, and must also support multi-field combined queries. Second, documents have long length and contain large numbers of professional charts. Parsing interfaces must adapt to large file sizes and long parsing durations. Third, the presence of professional terms and specific units requires that retrieval and parsing links retain original fields and units, with no arbitrary conversion. Fourth, some research reports contain undisclosed clinical data. Interfaces must add permission verification steps to restrict unauthorized access.

How to Set the Configuration

Configuration Item	Recommended Value	Rationale
`PARSE_FILE_TIMEOUT_SECONDS`	`600 seconds`	Medical device research reports typically contain large numbers of charts and clinical data, with parsing times significantly longer than general documents
`RECALL_TOP_K`	`Top 10 results`	Medical device content has high professional terminology density, requiring more retrieval results to cover relevant search content
`SIMILARITY_THRESHOLD`	`0.72–0.78`	Professional semantic similarity thresholds need to be higher than general scenarios to avoid missing accurately matched report content
`UPLOAD_FILE_MAX_SIZE`	`500 MB`	A single medical device research report may contain multiple pages of high-resolution images, so file sizes are generally larger than general documents
`INCREMENTAL_SYNC_INTERVAL`	`Every hour`	New approved medical device research reports are updated at a high frequency, requiring timely synchronization of the latest data
`FIELD_MAPPING_RULE`	`Map by registration certificate number and technical parameter classification`	The registration certificate number is the core identifier for medical device research reports, facilitating precise retrieval and classification

The parameter values provided on this page are common recommended starting points for configuration. Actual values are affected by material format, data volume, and business rules. Specific issues require targeted analysis, and it is recommended to test on your own samples before finalizing settings.

Three Common Configuration Mistakes

Calling the /api/knowledge/base/doc/parse interface returns 413 Request Entity Too Large. Cause: The UPLOAD_FILE_MAX_SIZE configuration was not adjusted to match the volume threshold for medical device research reports.
Calling the /api/knowledge/content interface returns an Unsupported file format error. Cause: The docx format commonly used for medical device research reports was not added to the allowed parsing file type whitelist, or the link did not correctly carry the file header identifier.
Calling initialization-related interfaces returns 504 Gateway Timeout. Cause: The PARSE_FILE_TIMEOUT_SECONDS configuration value is less than the actual time required to parse a single long research report.

How to Confirm the Configuration is Correct

Send a curl test request, upload a single medical device research report docx file, and check that the returned parse_status field is success.
Call the /api/knowledge/retrieval interface, pass the registration certificate number as the search keyword, and check that the returned results include the core technical parameters and unit information of the corresponding research report.
View the incremental synchronization logs, confirm that the latest medical device research report data is automatically pulled every hour, with no timeout or format error prompts.
Call the /api/admin/initv490 interface, check that the returned code field is 200, with no error messages about configuration conflicts.
