Carrier Particle Entrapment for In-Vitro Diagnostic QC Materials

Solution Overview

Problem

In in-vitro diagnostic systems, QC substances in the same solution can interfere with each other or with different detectors, affecting their performance and lifetime, leading to increased costs and downtime due to frequent replacements of detector cartridges.

Innovation Solution

The use of carrier particles, such as silica or polymeric particles, to entrap interfering QC substances, preventing them from interacting with other substances or detectors, thereby isolating the interfering substances and maintaining detector performance and longevity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If multiple QC substances are combined into a single QC material, then the number of QC procedures is reduced, but interference between QC substances occurs

Engineering Contradiction:
Core Design Contradiction:
ProductivityVSObject-generated harmful factors

Solution Approach 1:

The patent divides the QC material into separate compartments or chambers, each containing specific QC substances. This segmentation prevents interference between different QC substances while allowing them to be handled as a single integrated QC material, thus maintaining reduced procedure count while eliminating harmful interactions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces an intermediary substance or matrix that physically separates QC substances from each other and from detector surfaces. This intermediary prevents direct contact and interference between QC substances while maintaining their functional integrity for calibration and quality control purposes.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Device complexity

If QC substances are present in the same solution, then the number of calibration solutions is reduced, but detector performance and lifetime are affected

Engineering Contradiction:
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent segments the QC material into separate physical compartments or uses separate carrier particles for different QC substances. This ensures that each detector receives only the specific QC substance it needs, preventing degradation from unwanted substance interactions while maintaining simplified QC material management.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies local quality by providing different QC substances to different detectors or to different regions of the same detector system. Each detector receives the specific QC substance appropriate for its function, preventing harmful effects on detector performance and extending lifetime while maintaining overall system simplicity.

Inventive Principle:
Principle #3Local quality

3Reliability

If interfering QC substances are not isolated, then detector cartridges must be replaced frequently, but this increases costs and downtime

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent extracts or removes interfering QC substances from the detection environment by using selective carrier particles or compartmentalization. Only the necessary QC substances are present in the detection path, preventing degradation of detector cartridges and extending their operational life, thereby reducing replacement frequency and associated downtime.

Inventive Principle:
Principle #2Taking out (Extraction)
