Solution Overview

Problem

Existing packaging for negative pressure wound therapy systems is not user-friendly after components are removed, as it serves no further purpose and does not facilitate efficient disposal or retention of unused items.

Innovation Solution

A medical device packaging system with two detachable compartments, where one compartment contains the negative pressure pump and the other contains wound dressings and instructions, allowing the pump compartment to be discarded while the dressing compartment with instructions is retained for future use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a single integrated packaging box is used to contain all NPWT components, then all components can be stored together, but the packaging cannot be selectively disposed or retained after use

Engineering Contradiction:
Improveselective retention and disposalVSAvoidpackaging structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The packaging is divided into two separate compartments: a first compartment for the negative pressure pump and a second compartment for wound dressings and instructions. This segmentation allows the user to retain the second compartment with unused dressings and instructions while disposing of the first compartment, thereby achieving selective retention and disposal without significantly complicating the overall packaging structure.

Inventive Principle:
Principle #1Segmentation

2Loss of information

If instructions are provided separately from the packaging, then the packaging can be simplified, but users may lose access to instructions after removing components

Engineering Contradiction:
Improveinstruction accessibilityVSAvoidpackaging usability
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

The instructions are merged with the second compartment of the packaging, which is retained by the user after use. This ensures that instructions remain accessible to users without requiring separate documentation, while the integrated design maintains ease of operation by keeping instructions with the relevant components.

Inventive Principle:
Principle #5Merging (Combining)

3Loss of substance

If all packaging materials are retained after use, then nothing needs to be disposed of, but environmental waste increases and storage space is consumed

Engineering Contradiction:
Improvepackaging wasteVSAvoidpackaging design
Core Design Contradiction:
Loss of substanceVSEase of manufacture

Solution Approach 1:

The packaging is segmented into two compartments with different disposal characteristics. The first compartment containing the pump is designed for disposal, while the second compartment with dressings and instructions is designed for retention. This segmentation enables selective waste reduction without complicating the manufacturing process.

Inventive Principle:
Principle #1Segmentation

4Adaptability or versatility

If the packaging is designed for complete disposal, then manufacturing is simplified, but users cannot retain unused components for future use

Engineering Contradiction:
Improvecomponent retentionVSAvoidpackaging structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The packaging structure is segmented into a first compartment for disposable components and a second compartment for retainable components. This allows users to retain unused wound dressings and instructions while the pump compartment is disposed of, achieving component retention without significant structural complexity.

Inventive Principle:
Principle #1Segmentation

AI summary

Disclosed herein are several embodiments of medical device packaging, and more particularly to a reduced pressure therapy kit and packaging and methods of using the same in the treatment of wounds. Some embodiments are directed towards packaging including a dressing compartment for storing wound dressings and having use instructions printed thereon, the dressing compartment detachably connected to a pump compartment for storing a sterile pump. After removal of the pump, the pump compartment can be detached from the dressing compartment and discarded. The dressing compartment can be retained together with any additional dressings and the use instructions.
