Data Characteristics
High-value consumables regulations and SOP data primarily originate from internal medical institution policy documents, operational procedure manuals, supplier product specifications, and national or local medical device regulatory guidelines. This data typically exists in formats such as PDFs, Word documents, and structured database records. Update frequency is influenced by policy adjustments, product iterations, and clinical practice optimizations, with annual or on-demand updates being common. Document structures for regulations often include chapters on general principles, responsibilities, procurement, warehousing, usage, maintenance, and disposal. SOPs detail specific operational steps, precautions, and anomaly handling. Fields and units are highly specialized, covering product batch numbers, expiration dates, sterilization methods, storage conditions (e.g., "2-8°C", "avoid light"), usage departments, and operator qualifications. Date formats, temperature units (Celsius), and quantity units (pieces, sets, tablets) must be precise.
Constraints on Tool Calling and Plugins
The specialized nature of high-value consumables data imposes strict requirements on tool calling. First, the semi-structured or unstructured nature of documents, such as tables in PDFs or text embedded in images, demands robust document parsing capabilities from the RAG system. This ensures accurate extraction of critical information like product batch numbers and expiration dates. Second, the uncertain update frequency means that knowledge base synchronization strategies must support incremental updates and effectively handle version differences. This prevents the citation of outdated or obsolete regulations. The precision required for high-value consumables fields and units, such as temperature, humidity, and expiration dates, necessitates strict validation of data types and ranges during parameter passing in tool calls. For example, temperature parameters should be limited to numerical types with unit recognition. Furthermore, regulatory inquiries concerning high-value consumables often require information integration across multiple documents and sections. For instance, a procurement process for a specific consumable might require combining procurement regulations with usage specifications for that consumable. This challenges the system's ability for chained tool calls and multi-source information fusion.
Configuration Settings
| Configuration Item | Suggested Value | Rationale |
|---|---|---|
chunkSize | 800–1200 characters | Balances context length with semantic integrity, accommodating long sentences and complex paragraphs in regulatory documents. |
overlapSize | 100 characters | Ensures contextual continuity between segments, preventing critical information from being split. |
maxContext | 4000 tokens | Covers multiple relevant paragraphs required for typical regulatory inquiries, considering model processing capacity. |
similarityThreshold | 0.78–0.85 | Filters out low-relevance results, improving the precision of retrieved content and reducing noise. |
recallCount | top 5 | Prioritizes the return of the most relevant regulatory clauses, preventing the model from processing excessive redundant information. |
PARSE_FILE_TIMEOUT_SECONDS | 600 seconds | Handles the time-consuming parsing of complex PDF documents, especially those containing numerous tables and images. |
Common Pitfalls
- Symptom: Incorrect or missing consumables expiration date information returned by the system. Reason: The document parser failed to correctly identify date formats within tables in PDFs, leading to field extraction failure or parsing errors.
- Symptom: A user asks about storage conditions for a consumable, but the system returns procurement procedures. Reason: Inappropriate knowledge base segmentation strategy, where specific descriptions of storage conditions are mixed with procurement procedures in the same segment, or the similarity recall failed to distinguish subtle semantic differences.
- Symptom: Calling an external API to query consumable inventory returns a 400 error. Reason: The
product_batch_idfield passed to the API is empty or does not conform to the API's required format, possibly due to inaccurate extraction during document parsing.
Verification Steps
- Upload a typical high-value consumables regulation PDF document. Check if the parsed segments are complete and semantically coherent, especially for critical information such as dates and temperatures.
- Ask specific questions about the storage, usage, and disposal of particular high-value consumables. Verify that the system's answers accurately cite the corresponding regulatory clauses.
- Test the tool calling functionality, such as querying the expiration date of a specific batch of consumables. Review the tool call logs to confirm the accuracy of parameters in the
payloadand compare the external API's return results with expectations.
