Data Characteristics
Home medical product data comes from various sources. These include manufacturer websites, product manuals, technical documents, clinical trial reports, and user feedback platforms. Data updates are infrequent, typically occurring with product iterations or regulatory changes. Examples include annual new versions or revised instructions. Product documentation often uses PDF, Word, or structured XML formats. Content covers product specifications, usage instructions, contraindications, maintenance, and troubleshooting. Common fields include product_model, serial_number, batch_number, expiration_date, registration_number, and target_user. Units vary; blood pressure monitors use mmHg, and blood glucose meters use mmol/L or mg/dL. Measurement results typically include a timestamp and value.
Constraints on HTTP Interfaces and External Systems
The low update frequency of home medical product data means real-time synchronization is not critical. However, data accuracy and completeness are paramount. Diverse document structures, such as PDF and XML, require robust document parsing capabilities from HTTP interfaces. These interfaces must handle various unstructured and semi-structured data formats. Field names and units lack standardization. For example, blood glucose concentration units differ. Interfaces must perform unit conversion or clearly label units during data ingestion to avoid confusion. Some data may involve user health privacy. HTTP interfaces must follow strict security protocols, such as HTTPS encryption, for data transmission and storage. Due to long product lifecycles, there is a high demand for querying historical data and older document versions. Interfaces need to support effective indexing and retrieval of versioned data.
Configuration Guide
| Configuration Item | Recommended Value | Rationale |
|---|---|---|
API_ENDPOINT | Manufacturer's official open API or data service interface | Ensures authoritative and accurate data sources |
REQUEST_TIMEOUT_SECONDS | 60 seconds | Most manufacturer API response times are within a reasonable range, avoiding long waits |
MAX_BODY_SIZE_MB | 100 MB | Accounts for potentially large PDF or XML documents, allowing sufficient request body size |
AUTH_TOKEN_LIFETIME_HOURS | 24 hours | Reduces frequent token refreshes, balancing security and convenience |
RETRY_ATTEMPTS | 3 times | Addresses transient network fluctuations or temporary server overload, improving request success rate |
DATA_PARSING_SCHEMA | Calibrated based on actual measurements | Defined according to the specific product document's XML Schema or JSON Schema |
Common Pitfalls
- Receiving a
413 Payload Too Largeerror when calling the interface. This occurs when the uploaded document or data package size exceeds the server's limit. - Interface returns empty field values or inconsistent units. This happens due to incorrect data parsing rule configuration or missing unit conversions.
- Some old product information is not updated after data synchronization. This indicates a failure to correctly process the version control fields provided by the manufacturer.
Verification Steps
- Call the interface to retrieve complete information for a typical product. Verify key fields like
product_modelandregistration_numberagainst official documentation. - Upload a request containing different data formats (e.g., PDF manual and XML specification). Check if the system correctly parses and extracts text content.
- Simulate a data update operation. Confirm the system identifies and processes changes in
version_numberto synchronize the latest information.
