Development of a bio-inspired wound model for debridement training

Area of Science:

• Biomedical Engineering
• Medical Simulation
• Wound Care Technology

Background:

• Wound debridement is crucial for healing, but clinical training lacks realistic simulation tools.
• Current training methods using citrus peels or porcine skin do not accurately replicate wound textures.
• There is a significant need for effective, safe simulation models for debridement practice.

Purpose of the Study:

• To design and develop a life-like wound model for simulation-based training in wound debridement.
• To provide practitioners with a tool that mimics the tactile and visual feedback of clinical wound debridement.
• To enhance debridement proficiency and confidence before patient interaction.

Main Methods:

• Development of a multi-layered wound model with realistic necrotic eschar, slough, and granulation tissue.
• Incorporation of healthy skin layers with biomechanical properties similar to human skin.
• Mechanical testing of the necrotic eschar to validate its brittle fracture behavior.

Main Results:

• The model successfully replicates the visual and haptic feedback of debriding various wound tissue types.
• The slough layer exhibits appropriate viscosity for realistic removal with debridement tools.
• The necrotic eschar demonstrates brittle fracture characteristics consistent with clinical observations.

Conclusions:

• The developed life-like wound model provides an effective and safe platform for debridement simulation training.
• This tool can significantly improve practitioner confidence and competence in wound debridement.
• Personalized wound models incorporating deeper structures like bone or tendon are feasible, further enhancing training realism and patient care.
