Solution Overview

Problem

Existing fluid sample collection containers generate excessive sharps waste and pose a risk of needle-stick injuries due to the non-removable integration of finger grip luer adapters (FGLAs) in the container lids.

Innovation Solution

A container assembly with a removably coupled finger grip luer adapter (FGLA) and a separate cap and removal tool that encloses the needle, allowing the FGLA to be separated from the lid and disposed of separately, reducing sharps waste and protecting users from needle-stick injuries.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the finger grip luer adapter is non-removably integrated into the container lid, then the sample collection function is simplified and reliable, but the sharps waste volume increases and needle-stick injury risk increases

Engineering Contradiction:
Improvesample collection functionVSAvoidsharps waste volume
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The finger grip luer adapter is divided into a removable component that can be separated from the container lid. This segmentation allows the sharp needle portion to be disposed of separately from the non-sharp lid portion, reducing sharps waste volume while maintaining the reliability of the sample collection function during use.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The sharp needle component is extracted from the integrated lid structure and made removable. This extraction allows the hazardous sharp portion to be separated and disposed of in sharps containers, while the non-hazardous lid can be disposed of separately, reducing overall sharps waste volume.

Inventive Principle:
Principle #2Taking out (Extraction)

2Device complexity

If the finger grip luer adapter is non-removably integrated into the container lid, then the device structure is simplified, but the needle-stick injury risk increases

Engineering Contradiction:
Improvedevice structureVSAvoidneedle-stick injury risk
Core Design Contradiction:
Device complexityVSObject-affected harmful factors

Solution Approach 1:

The device is segmented into removable and non-removable portions, with the sharp needle component being removable. This segmentation enables safe removal of the hazardous portion after use, reducing needle-stick injury risk while maintaining structural simplicity during the collection process.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The hazardous needle component is extracted as a removable element from the lid structure. This allows the sharp portion to be taken out and disposed of safely after use, eliminating the needle-stick injury risk associated with integrated non-removable adapters.

Inventive Principle:
Principle #2Taking out (Extraction)

3Loss of substance

If the finger grip luer adapter is made removable, then the sharps waste volume is reduced, but the device complexity increases

Engineering Contradiction:
Improvesharps waste volumeVSAvoiddevice structure
Core Design Contradiction:
Loss of substanceVSDevice complexity

Solution Approach 1:

The adapter is segmented into removable and fixed portions with a simple connection interface. This segmentation reduces sharps waste by allowing separate disposal of the needle portion, while the simple interface design minimizes the increase in device complexity.

Inventive Principle:
Principle #1Segmentation

AI summary

A container assembly including a collection container and a container lid couplable to the collection container. An elongate receptacle extends from the container lid into the collection container when the container lid is coupled to the collection container. The elongate receptacle has an open end portion defined within the container lid and is configured to receive a specimen collection tube therein. A finger grip luer adapter is removably coupled to the container lid within the elongate receptacle, the finger grip luer adapter having a needle extending therefrom. An elongate cap is removably coupled to the finger grip luer adapter and is configured to extend over at least the needle of the finger grip luer adapter, wherein an upper portion of the elongate cap extends above at least a portion of the open end portion of the elongate receptacle when coupled to the finger grip luer adapter.
