    Area of Science:

    • Biomaterials Science
    • Biomechanics
    • Medical Device Engineering

    Background:

    • Soft silicone multi-layer dressings are utilized for pressure injury prevention.
    • Dressing efficacy is contingent upon design, construction, and material characteristics.

    Purpose of the Study:

    • To evaluate the protective effectiveness of the ALLEVYN COMPLETE CARE (ACC) dressing.
    • To assess ACC's capacity to mitigate strain and stress concentrations in soft tissues.

    Main Methods:

    • Frictional energy absorber effectiveness (FEAE) testing was employed.
    • Computational finite element modeling was utilized.
    • Testing simulated clinically relevant conditions for posterior heel support.

    Main Results:

    • The ACC dressing exhibited significant internal layer-to-layer frictional sliding.
    • FEAE reached 93% under simulated clinical conditions.
    • The dressing effectively dissipated shear forces, reducing tissue strain and stress concentrations, eliminating peak values.

    Conclusions:

    • The ACC dressing demonstrates enhanced protective capacity compared to previous generations.
    • Advanced testing methods provide insights into effective pressure ulcer prevention dressing design.
    • The ACC dressing's structure facilitates shear force dissipation, crucial for pressure injury prevention.
