Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wound care technologies are inadequate for effectively cleansing, desloughing, and debriding wounds due to high costs, untidiness, and inefficiency in removing devitalized tissue and bacterial biofilms, which hinder healing and increase infection risk.
Innovation Solution
A wound-care device that generates low-frequency vibrations and oscillations, adjustable for different tissue consistencies, combined with a fluid system for irrigation, to facilitate wound cleansing, desloughing, and debridement, designed for ease of use by various skill levels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ultrasonic debridement is used, then debridement effectiveness is improved, but cost increases making it not widely adoptable
Solution Approach 1:
The patent replaces expensive ultrasonic debridement systems with a mechanically simpler oscillating blade system. The oscillating blade uses basic mechanical oscillation mechanisms rather than complex ultrasonic transducers, achieving effective debridement at lower cost and enabling wider adoption in clinical settings.
Solution Approach 2:
The patent employs disposable oscillating blade attachments that can be easily replaced. This approach eliminates the need for expensive, maintainable ultrasonic equipment while providing effective debridement through simple, disposable mechanical components.
2Ease of operation
If pulse lavage is used, then wound cleansing is achieved, but it is too untidy for use in clinic or emergency room settings
Solution Approach 1:
The patent combines debridement and cleansing functions into a single integrated device. The oscillating blade performs debridement while simultaneously generating controlled fluid flow for cleansing, eliminating the need for separate pulse lavage equipment and reducing overall system complexity and tidiness requirements.
Solution Approach 2:
The device segments the cleansing function into a controlled, localized fluid delivery system integrated with the oscillating blade, rather than using broad-spectrum pulse lavage. This targeted approach achieves effective cleansing with minimal fluid dispersion, maintaining a tidier clinical environment.
3Adaptability or versatility
If adjustable vibration frequencies are used, then adaptability to different tissue consistencies is improved, but device complexity increases
Solution Approach 1:
The patent implements adjustable oscillation frequencies that allow the device to adapt to different tissue consistencies (e.g., soft slough vs. harder necrotic tissue). The frequency adjustment mechanism is designed to be simple and intuitive, enabling clinicians to optimize performance for various wound types without excessive complexity.
