Solution Overview

Problem

Current medical waste management is inefficient due to separate packaging of catheter stabilization devices, leading to increased environmental impact and complexity in securing IV catheters post-procedure.

Innovation Solution

A medical device package integrating a cover, packaging paper, and an adhesive dressing sealed within, where the adhesive dressing is removably attached to the packaging paper, allowing for secure attachment of the medical device to a patient's skin while maintaining sterility and compatibility with EtO and gamma sterilization.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of substance

If separate packaging is used for catheter stabilization devices, then device functionality is maintained, but medical waste increases and environmental impact worsens

Engineering Contradiction:

Improvemedical wasteVSAvoidpackaging structure

Core Design Contradiction:

Loss of substanceVSDevice complexity

Solution Approach 1:

The patent combines the catheter stabilization device with the packaging paper into a single integrated unit. The adhesive dressing is applied directly to the packaging paper, eliminating the need for separate packaging for the stabilization device. This merging reduces medical waste by allowing the packaging paper to serve dual purposes: containing the catheter during storage/transport and stabilizing the catheter after insertion.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The packaging paper is designed to perform multiple functions: it serves as the primary packaging material for the catheter, provides a sterile barrier, and simultaneously acts as the base for the adhesive dressing that stabilizes the catheter. This multi-functionality eliminates the need for additional separate packaging components.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

If multiple separate products are used for catheter stabilization, then comprehensive stabilization is achieved, but the number of packaging materials increases

Engineering Contradiction:

Improvecatheter stabilizationVSAvoidpackaging materials

Core Design Contradiction:

ReliabilityVSQuantity of substance

Solution Approach 1:

The stabilization function is merged into the packaging paper itself through the application of adhesive dressing. Instead of requiring a separate stabilization device, the packaging paper becomes the stabilization medium, reducing the quantity of packaging materials while maintaining reliable catheter stabilization.

Inventive Principle:

Principle #5Merging (Combining)

3Loss of substance

If adhesive dressing is integrated into packaging paper, then waste is reduced, but sterility maintenance becomes more challenging

Engineering Contradiction:

Improvemedical wasteVSAvoidsterility

Core Design Contradiction:

Loss of substanceVSReliability

Solution Approach 1:

The adhesive dressing is applied to the packaging paper during the manufacturing process while the packaging materials are still in their sterile state. This preliminary action ensures that the adhesive is already in place before sterilization, allowing the entire integrated structure to be sterilized as a single unit and maintain sterility until use.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The packaging paper with integrated adhesive dressing serves its own sterilization needs through compatibility with EtO and gamma sterilization methods. The materials are selected to be self-compatible with these sterilization processes, maintaining sterility without requiring additional protective measures.

Inventive Principle:

Principle #25Self-service

4Ease of manufacture

If packaging paper is used as stabilization device, then cost is reduced, but compatibility with sterilization methods must be ensured

Engineering Contradiction:

Improvemanufacturing costVSAvoidsterilization compatibility

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The packaging paper materials are selected and their parameters are optimized to be compatible with specific sterilization methods (EtO and gamma sterilization). By adjusting material parameters such as chemical composition and structural properties, the packaging paper achieves both cost-effectiveness and sterilization compatibility.

Inventive Principle:

Principle #35Parameter changes

AI summary

A medical device packaging assembly includes a cover (10), a medical packaging paper (20), a medical device (50), and an adhesive dressing (30). The cover has a pocket (14) and a perimeter (12) extending from the perimeter of the pocket. The medical packaging paper forms a hermetically tight seal between the medical packaging paper and the perimeter of the cover around the pocket. The medical device is contained in the hermetically sealed pocket along with the adhesive dressing. The adhesive dressing is removably adhered to the medical packaging paper.
