Protective Coating for Wound Fluid Activation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wound treatment fluids with active molecules often degrade when exposed to materials or light, reducing their effectiveness in delivering therapeutic benefits to the wound site due to lack of protection during delivery and application in existing systems.
Innovation Solution
A wound treatment system that includes a fluid storage device with molecules coated for protection, coupled with an energy source that degrades the protective coating at the wound site, activating the therapeutic properties of the fluid, which can include anti-biotic, analgesic, or debridement properties, using various energy forms like ultrasonic, magnetic, or light energy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wound treatment fluids are delivered through tubing and plastic components, then the fluid can be transported to the wound site, but the active molecules in the fluid degrade due to contact with materials and light exposure
Solution Approach 1:
The patent applies preliminary action by coating active molecules with a protective layer before delivery through the system. This protective coating prevents degradation during transport through tubing and exposure to light, ensuring the molecules remain effective until they reach the wound site where they are then activated
Solution Approach 2:
The protective coating acts as an intermediary between the active molecules and the harmful environment (tubing materials and light). This intermediary layer shields the sensitive molecules during delivery while allowing controlled activation at the target site
2Reliability
If protective coating is applied to active molecules, then degradation during delivery is prevented, but the therapeutic property remains inactive until activation
Solution Approach 1:
The protective coating is applied in advance to protect molecules during storage and transport. The coating remains in place until the fluid reaches the wound site, where controlled activation occurs through energy input (such as light or heat), converting the protected state to the active therapeutic state at the appropriate time
3Measurement precision
If energy source is used to activate therapeutic property at wound site, then accurate activation is achieved, but system complexity increases
Solution Approach 1:
The system utilizes the wound site environment itself to trigger activation. For example, the body's natural heat or light exposure at the wound site can activate the therapeutic molecules without requiring complex external energy delivery systems, thereby achieving precise local activation while minimizing added system complexity
