Sensor Transmitter Assembly Traceability for Glucose Calibration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blood glucose meters require frequent blood sampling, making it inconvenient for diabetic patients to monitor changing glucose levels, and the calibration process can be cumbersome, especially for the elderly or those unfamiliar with the devices, while also posing challenges in tracking defective sensor transmitters during manufacturing.
Innovation Solution
A method of manufacturing a sensor transmitter for continuous blood glucose measurement that generates quality management information mapping production information of a sensor and transmitter, creating a readable quality management code for easy calibration input and attaching it to packaging, allowing for efficient tracking of defective units through a server-based system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a blood-collecting type blood glucose meter is used for blood glucose control, then blood glucose measurement can be performed, but the burden of frequent blood collection is huge and it is difficult to precisely monitor frequently changing blood glucose levels
Solution Approach 1:
The patent replaces the mechanical blood collection process with a continuous glucose monitoring system that uses a sensor to detect glucose levels in interstitial fluid. The sensor transmitter continuously measures glucose without requiring repeated blood draws, substituting the mechanical puncture method with an optical/electrochemical sensing system that provides continuous data streams for accurate monitoring.
2Ease of operation
If initial calibration information is printed on packaging for user input, then calibration can be performed, but it is inconvenient for elderly or unfamiliar users to input the information accurately
Solution Approach 1:
The system enables self-service calibration by automatically reading the initial calibration information through the quality management code on the packaging. The communication terminal autonomously captures and processes the calibration data without requiring manual transcription by the user, eliminating errors from manual input while maintaining ease of use.
Solution Approach 2:
The quality management code serves as an intermediary between the packaging information and the communication terminal. Instead of requiring direct user interaction to transfer calibration information, the code acts as a machine-readable mediator that automatically transmits the data, bridging the gap between physical packaging and digital processing.
3Productivity
If sensor and transmitter are assembled during manufacturing, then sensor transmitter can be produced, but defective units are difficult to track through distribution paths
Solution Approach 1:
The patent applies preliminary action by generating quality management information that maps sensor and transmitter production information to each other during the assembly process. This mapping is established before the products enter distribution channels, creating a traceable linkage that enables tracking of defective units throughout the distribution path without interfering with manufacturing efficiency.

AI summary
The present disclosure relates to a manufacturing method for a sensor transmitter for continuous glucose monitoring and, more particularly, to a manufacturing method for a sensor transmitter, capable of generating quality control information in which production information of a sensor and production information of a transmitter that are used for the sensor transmitter during an assembly process of the sensor transmitter are mapped to each other, and storing and managing the generated quality control information in a server, so as to monitor a distribution channel or a sales channel of the sensor transmitter by using the quality control information, use for quality control of the sensor transmitter, or easily track a bad sensor transmitter.
