Solution Overview

Problem

Current Negative Pressure Wound Therapy (NPWT) systems require specific and compatible suction units and dressings from the same manufacturer, leading to inventory management issues, increased operational costs, and complexity in application due to the need for multiple devices and power sources, as well as challenges in sealing and compatibility with different anatomical contours.

Innovation Solution

An alternative dressing with a sealed top surface using adhesive tape for simplified application, a universal coupler for interfacing with different suction sources, and a regulation unit that can connect to various NPWT systems, reducing the need for multiple inventories and power sources, and allowing for customizable pressure profiles and alarm functions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manufacturer-specific suction units and dressings are used, then compatibility and seal integrity are improved, but device complexity and inventory management difficulty increase

Engineering Contradiction:
Improveseal integrityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent applies universality by designing a universal coupler that can interface with dressings from multiple manufacturers (KCI, Genedyne, Convatec, Smith & Nephew) through standardized connection interfaces. This allows a single suction unit to work with various dressing systems, reducing device complexity while maintaining seal integrity through proper adapter design.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The universal coupler acts as an intermediary component between the suction unit and the dressing system. It provides standardized connection interfaces that accommodate different manufacturer specifications, enabling compatibility without requiring manufacturer-specific components for each system.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If multiple manufacturer-specific devices are used, then system compatibility is improved, but operational costs and inventory management increase

Engineering Contradiction:
Improvesystem compatibilityVSAvoidinventory quantity
Core Design Contradiction:
Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The universal coupler enables a single suction unit to interface with dressings from multiple manufacturers (KCI, Genedyne, Convatec, Smith & Nephew), providing system compatibility across different vendor ecosystems. This reduces the need to maintain separate inventories for each manufacturer's proprietary components.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The invention merges multiple manufacturer-specific connection interfaces into a single standardized universal coupler design. This consolidation combines the functionality of multiple proprietary adapters into one universal component, reducing inventory quantity while maintaining compatibility with various systems.

Inventive Principle:
Principle #5Merging (Combining)

3Reliability

If adhesive film is applied over sponge material, then sealing is improved, but application time and complexity increase

Engineering Contradiction:
ImprovesealingVSAvoidapplication time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The dressing is designed with the sealing layer and adhesive film already integrated and positioned in advance during manufacturing. The adhesive film is pre-applied to the sponge material with proper alignment, eliminating the need for time-consuming manual application steps during clinical use while maintaining reliable sealing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The sealing layer and adhesive film are merged into a single integrated component assembly that is applied as one unit. This integration combines the sealing function and adhesive bonding into a single application step, reducing overall application time while ensuring proper sealing integrity.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If proprietary adaptors are used for each manufacturer, then interface compatibility is improved, but device complexity and operational difficulty increase

Engineering Contradiction:
Improveinterface compatibilityVSAvoidease of operation
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The universal coupler provides a single standardized interface that is compatible with dressings from multiple manufacturers (KCI, Genedyne, Convatec, Smith & Nephew). This eliminates the need for medical professionals to learn and switch between multiple proprietary adaptor configurations, significantly improving ease of operation while maintaining broad interface compatibility.

Inventive Principle:
Principle #6Universality (Multi-functionality)

AI summary

A Negative Pressure Wound Therapy (NPWT) dressing having a sealing layer on a non-wound interfacing surface. Such a sealed surface eases application and reduces the risk of a loss of seal once applied to a patient. Associated adaptors and couplers, which may be universal couplers, allow for simplified use of the disclosed and existing dressings. An optional pressure regulator unit may use existing wall suction available in medical facilities; it may interface with a transportation unit. Embodiments of the regulation unit provide for various monitoring, operation and alarming features that may be accessed using mobile wireless, wireless LAN, and internet based connectivity approaches.
