Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional rapid diagnostic systems for capillary blood analysis are bulky due to separate components for pricking, collecting, and buffer solution, which complicates manipulation and increases space requirements.
Innovation Solution
A compact rapid analysis system integrating a pricking member, a collecting member with a fixed duct, and an immunochromatographic strip within an elongated analysis module, with a separate container for the buffer solution, optimizing the footprint and simplifying use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If separate components (pricking member, collecting member, buffer solution) are used in conventional rapid diagnostic systems, then the system is simple to manufacture and operate, but the device occupies large space and requires complex manipulation
Solution Approach 1:
The patent combines the pricking member, collecting member with fixed duct, and immunochromatographic strip into a single integrated analysis module. This merging of previously separate components reduces the overall footprint while maintaining operational simplicity, as the integrated design eliminates the need for multiple separate manipulations.
Solution Approach 2:
The analysis module serves multiple functions within a single device: it performs capillary blood collection, sample transport via fixed duct, and immunochromatographic analysis. This multi-functionality reduces the number of separate devices needed, thereby reducing space requirements while maintaining ease of use.
2Ease of manufacture
If separate components are used for capillary blood analysis, then each component can be optimized independently, but the overall device complexity and manipulation steps increase
Solution Approach 1:
By merging the pricking member, collecting member, and immunochromatographic strip into one analysis module, the patent reduces the number of manipulation steps required. Users no longer need to handle separate components independently, thereby reducing device complexity from the user perspective while maintaining manufacturing optimization capabilities.
3Ease of operation
If all elements are integrated into an 'all-in-one' device, then the system is simple to use with reduced manipulation steps, but the device occupies excessive space for patient-side operations
Solution Approach 1:
The patent segments the buffer solution from the analysis module by providing it in a separate container. This segmentation allows the analysis module to remain compact for patient-side use while still providing access to necessary reagents, thereby reducing footprint without compromising ease of operation.
Solution Approach 2:
The fixed duct acts as an intermediary component that efficiently transports the capillary blood sample from the collecting member to the immunochromatographic strip within a compact configuration. This intermediary structure enables space-efficient integration of functional components.

AI summary
Disclosed is a system for rapid analysis of a capillary blood sample from a subject, intended for detecting the presence of at least one analyte in the capillary blood sample. The rapid analysis system includes an analysis module in which is incorporated at least one immunochromatographic strip. The analysis module includes: a pricking member, suitable for generating a drop of capillary blood; and a collecting member, including a fixed duct, suitable for capillary blood to flow therethrough. The duct has an inlet suitable for collecting the drop of capillary blood, and an outlet, arranged opposite the deposition area and suitable for depositing the drop of capillary blood onto the deposition area, and a container, separate from/independent of the analysis module, in which is packed a buffer solution suitable for implementing the immunochromatographic technique.
