Integrated Blood Glucose Meter Strip Cartridge Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing integrated blood glucose measuring devices have complex structures and operation methods, leading to inefficient supply and discharge of test strips, which can result in degradation and reduced measurement accuracy.
Innovation Solution
An integrated blood glucose measuring device with a strip cartridge that allows test strips to be supplied and discharged one by one using a manipulation knob's linear movement in two stages, ensuring the sealing function is maintained, thus protecting the strips and enhancing measurement accuracy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate strip storage case is used, then test strips can be stored, but the device structure becomes complex and operation becomes inconvenient
Solution Approach 1:
The patent combines the strip storage case and blood glucose meter into a single integrated device. The strip cartridge is inserted into the meter housing, merging two previously separate components (storage case and measurement device) into one unified system, thereby reducing overall device complexity while maintaining storage functionality
Solution Approach 2:
The integrated device performs multiple functions: it stores multiple test strips in the cartridge and simultaneously measures blood glucose. The single device replaces the need for separate storage and measurement equipment, providing multi-functionality that reduces the number of components the user must manage
2Ease of operation
If the strip cartridge is opened frequently, then test strips can be accessed, but the sealing function deteriorates and test strips degrade
Solution Approach 1:
The device opens the strip cartridge only when a test strip is actually needed for measurement. The strip supply mechanism is designed to advance the next strip only after the previous one has been used, ensuring the cartridge remains sealed during storage periods and opening it only at the moment of use, thereby preserving the sealing function
Solution Approach 2:
The strip supply mechanism automatically advances to the next test strip after the current one is removed, without requiring manual intervention to open the cartridge. The system self-manages the strip supply process while maintaining the sealed environment, opening the cartridge only when necessary and closing it automatically afterward
3Productivity
If test strips are not discharged accurately, then measurement efficiency decreases, but the device structure becomes simpler
Solution Approach 1:
The strip discharge process is divided into two distinct stages: first, the strip is pushed to the discharge position; second, the strip is fully ejected from the device. This segmentation of the discharge action into separate mechanical steps enables precise control over strip positioning and ejection, improving supply accuracy through a structured two-phase mechanism

AI summary
The present invention relates to an integrated blood glucose measuring device. The present invention provides an integrated blood glucose measuring device which can accommodate a strip cartridge storing a plurality of test strips therein, and is configured to supply and discharge the test strips one-by-one from the strip cartridge by a method that involves moving a manipulation knob linearly in two separate stages. Thus, the integrated blood glucose measuring device has a simple operating method and structure, and can accurately perform the supplying and discharging of the test strips. Also, by ensuring that a supply opening of the strip cartridge is only open when operating the manipulation knob, the sealing function with respect to the strip cartridge can be stably maintained, thereby preventing the test strips from degrading even when used for a long time, and thereby the accuracy of blood glucose measurement results can be enhanced.
