Solution Overview
Problem
Current wound treatment methods for chronic wounds are inadequate in promoting lasting recovery, as they often rely on passive techniques that provide only temporary relief and do not effectively enhance healing conditions.
Innovation Solution
A multifunctional wound treatment dressing that integrates negative pressure, electrical stimulation, optical stimulation, and mechanical stimulation, along with a customizable and adaptable design, including sensors for monitoring wound parameters, to provide a comprehensive therapeutic approach that can be tailored to individual wounds.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple separate treatment methods are applied to chronic wounds, then the healing conditions can be improved, but the treatment complexity and time required for dressing changes increase
Solution Approach 1:
The patent combines multiple separate treatment modalities (negative pressure therapy, electrical stimulation, optical stimulation, mechanical stimulation, and exudate removal) into a single integrated wound treatment dressing. This allows all therapies to be administered simultaneously through one dressing application, eliminating the need for frequent dressing changes while maintaining comprehensive wound care.
Solution Approach 2:
The wound treatment dressing is designed as a multifunctional device that can perform various therapeutic functions (negative pressure application, electrical stimulation, optical stimulation, mechanical stimulation, and exudate removal) within a single system. This universal approach allows the same dressing to provide multiple benefits without requiring separate treatments or frequent replacements.
2Reliability
If passive treatment techniques are used for chronic wounds, then the wound is protected from further damage, but lasting recovery is not achieved
Solution Approach 1:
The patent transitions from static passive protection to dynamic active treatment by incorporating stimulable elements that can be activated to promote wound healing. The dressing includes capabilities for electrical stimulation, optical stimulation, and mechanical stimulation that actively enhance cellular processes and tissue regeneration, transforming the dressing from a protective barrier into an active healing catalyst.
Solution Approach 2:
The patent applies various physical parameters (electrical fields, optical energy, mechanical vibration, negative pressure) to alter the wound environment and stimulate healing processes. By changing these physical parameters, the dressing promotes active tissue regeneration, increased blood flow, and enhanced cellular activity, thereby accelerating the healing rate while maintaining wound protection.
3Ease of operation
If standard wound dressings are applied, then the treatment process is simple, but the therapy cannot be continuously adjusted based on wound status
Solution Approach 1:
The patent incorporates sensors that continuously monitor wound parameters (such as pH, temperature, moisture, and infection markers) and provide feedback to the control system. This feedback mechanism allows the dressing to automatically adjust treatment parameters (electrical stimulation intensity, optical energy delivery, negative pressure level) based on real-time wound status, ensuring optimal therapy without complex manual intervention.
Solution Approach 2:
The wound treatment dressing is designed to autonomously monitor and adjust its own treatment parameters based on sensor feedback from the wound site. The integrated control system automatically modulates the various therapeutic modalities without requiring frequent manual intervention or dressing changes, making the system both easy to operate and highly adaptable to changing wound conditions.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution enables continuous and flexible administration of various therapies without dressing changes, potentially accelerating healing by creating an optimized wound environment and allowing for real-time adjustments based on wound status, thereby reducing treatment time and improving outcomes.
Implementation Method 1
applying a sub-atmospheric pressure or a vacuum to the wound... Negative pressure draws fluid out of a wound, which inhibits bacterial growth, and furthermore draws blood into the wound
Implementation Method 2
specific types of electrical stimulation will alter the wound environment in a positive way... Electrical stimulation for instance leads to increased tissue oxygen levels as well as blood flow at the application area
Implementation Method 3
phototherapy (i.e. light therapy or heliotherapy) is commonly applied as anti-bactericidal treatment, wound healing treatment, antifungal treatment
Implementation Method 4
a vibrational energy source, such as an ultrasound transducer, arranged at the wrapping and adapted for transmitting vibrational energy towards the wound

AI summary
The present invention relates to a multifunctional wound treatment dressing for administering a plurality of different therapeutic treatments to an open, chronic wound of a human or animal body. The proposed multifunctional wound treatment dressing comprises an occlusive wrapping (3) adapted for placing over a wound (2). The proposed multifunctional wound treatment dressing further comprises at least two of the group of electrical, optical or mechanical stimulation means adapted for transmitting electrical, optical or mechanical energy towards the wound to stimulate healing of the wound and/or means for applying a negative (i.e. sub-atmospheric) pressure to the wound (2). Thus, a variety of different healing stimulation treatments are possible performed together or in sequence by wearing the same occlusive wrapping (3) without the need of changing/removing temporarily the wrapping (3) for each change of treatment method.
