Blood Glucose Meter Ejecting Unit for Controlled Strip Discharge
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing integrated blood glucose meters have complex structures and inefficient test strip supply mechanisms, making them inconvenient to use and prone to damage from external test strips and foreign materials.
Innovation Solution
An integrated blood glucose meter with a simple structure and operating method, featuring a strip cartridge that can be loaded and discharged using a linear movement of an operating knob, and an ejecting unit that allows for controlled removal of test strips via a pressing manipulation, preventing external interference and maintaining a stable internal state.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If test strips are ejected forcefully from the strip cartridge, then test strip discharge speed is improved, but external test strips and foreign materials may enter the internal space causing damage
Solution Approach 1:
The strip outlet serves as an intermediary component between the internal cartridge space and external environment. It is designed with controlled dimensions that allow only used test strips to pass through while blocking external test strips and foreign materials from entering the internal space, thus mediating the conflict between discharge speed and contamination prevention
Solution Approach 2:
The strip outlet structure预先 (in advance) prevents harmful factors from entering by designing a controlled opening that only allows outward movement of used test strips. This preliminary protective measure eliminates the need for complex sealing mechanisms while maintaining internal space protection
2Quantity of substance
If a separate strip storage container is carried, then test strip storage capacity is improved, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent merges the strip storage container with the blood glucose meter main body, creating an integrated device where the cartridge is inserted into a receiving space within the meter. This combination eliminates the need to carry separate containers while maintaining adequate test strip storage capacity
Solution Approach 2:
The integrated design makes the blood glucose meter multi-functional by combining storage, loading, and measurement functions into a single device. The cartridge serves both as storage container and as the measurement medium, while the meter provides both storage management and glucose measurement capabilities
3Ease of manufacture
If the strip cartridge structure is simplified, then ease of manufacture is improved, but test strip supply accuracy may deteriorate
Solution Approach 1:
The cartridge is segmented into distinct functional zones: a storage chamber for holding test strips, a controlled outlet for discharge, and a loading interface for insertion into the meter. This segmentation allows simple manufacturing of each zone while ensuring accurate test strip supply through the designed outlet geometry and loading mechanism

AI summary
The present invention relates to an integral blood glucose meter, and provides an integral blood glucose meter configured so as to be capable of receiving therein a strip cartridge for holding a plurality of test strips, and to enable the test strips to be loaded one by one from the strip cartridge by linearly moving an operation knob, and thus has a simple operation method and structure and enables accurately supplying and discharging the test strips, and enables the test strips to be conveniently discharged and removed after a blood glucose measuring procedure is completed by having an ejecting unit mounted thereto that may be pressed and operated so as to enable discharging and removing the test strips loaded at a strip discharge port, and enables more convenience in use by enabling the test strips to be discharged at an adequate speed by the operating force of a user without having the test strips shooting out too forcefully, and prevents damage to the internal structure and, at the same time, enables maintaining a stable operational state by preventing external test strips and foreign substances from entering.
