Solution Overview

Problem

Existing negative-pressure therapy systems lack efficient integration of fluid conductors and treatment indicators, limiting their effectiveness in wound care and tissue growth promotion.

Innovation Solution

A low-profile fluid conductor with integrated treatment indicators, such as a bridge, is used to facilitate the delivery of negative pressure and instillation therapy, enhancing wound care by promoting tissue growth and wound healing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional fluid conductors are used in negative-pressure therapy systems, then the system structure is simple, but the treatment monitoring capability is insufficient

Engineering Contradiction:
Improvetreatment monitoring capabilityVSAvoidsystem structure
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the fluid conductor and treatment indicator into a single integrated component. The indicator is embedded within the fluid conductor, allowing treatment monitoring to be performed directly through the existing fluid delivery pathway without adding separate monitoring devices. This merging approach enhances treatment reliability while avoiding significant increases in system complexity.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The fluid conductor serves multiple functions: it acts as both the fluid delivery pathway and the treatment indicator. By incorporating visual indicators directly into the conductor material or structure, the same component provides both fluid transport and treatment status monitoring, eliminating the need for separate dedicated monitoring elements.

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

2Measurement precision

If fluid conductors with integrated indicators are used, then real-time treatment monitoring is improved, but the manufacturing complexity increases

Engineering Contradiction:
Improvereal-time treatment monitoringVSAvoidmanufacturing complexity
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent utilizes thin film or flexible membrane structures as the fluid conductor, into which indicators can be easily embedded during the forming process. These thin-film structures allow for integrated indicator incorporation through coating, lamination, or molding techniques that are compatible with existing manufacturing processes, thereby achieving real-time monitoring without substantially increasing manufacturing complexity.

Inventive Principle:
Principle #30Flexible shells and thin films

3Shape

If low-profile fluid conductors are used, then the device profile is reduced for better patient comfort, but the fluid management efficiency may be compromised

Engineering Contradiction:
Improvedevice profileVSAvoidfluid management efficiency
Core Design Contradiction:
ShapeVSProductivity

Solution Approach 1:

The patent achieves a low-profile shape by transitioning the fluid conductor from a three-dimensional bulky structure to a two-dimensional thin-film or flat membrane configuration. This dimensional reduction improves patient comfort and device fit while maintaining fluid management efficiency through optimized two-dimensional fluid pathways and indicator integration across the film surface.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

An apparatus for use in treating a tissue site with negative pressure, which may comprise a fluid path between a first end and a second end. The fluid conductor may additionally comprise a plurality of pressure indicators configured to indicate a pressure state between the first end and the second end. In some examples, the fluid conductor may be fluidly coupled to a source of negative pressure and a dressing, which can be configured to be applied to a tissue site for treatment with negative pressure.
