Laboratory Research
A new five-layer silicone foam dressing* indicated for pressure injury prevention (PIP) and wound management was developed through extensive user research with more than a thousand healthcare professionals and hospital staff across the US.
The silicone foam dressing was designed to address their clinical needs and perform highly on key parameters for PIP and wound treatment.
Methods:
Tests were performed at SMTL (Surgical Materials Testing Laboratory) in UK, Danish Technical Institute (DTI) and Coloplast, Denmark.
SMTL: Fluid Handling Capacity (EN13726-1, Section 3.3); (n=5).
DTI: Waterproofness (EN 13726-3) (n=3).
Coloplast: interface pressure mapping, static and dynamic friction coefficients (n=29), peel adhesion and re-adhesion from steel plate (n= 44), relative swelling rise (n=11), retention of a foam dressing (n=11).
Results:
Results shown as Mean±SD:
Pressure redistribution (Pa/N) | Peak pressure 38,36 +/- 3,73 | Coefficient of Variation 2,84 +/- 0,15 |
Friction absorption | Static Friction Coefficient: 0,23 +/- 0,04 | Dynamic Friction Coefficient: 0,21+/-0,04 |
Microclimate | 24h fluid handling capacity (g/10cm2) 30.2 +/- 1.1 | |
| Waterproofness - pass | |
Peel adhesion and re-adhesion (N/25mm) | Peel adhesion no.1: 2.4 - no.2: 1.52- no.3: 1.44- no4: 1.39- no5: 1.35- no6: 1.28 | |
Shear | Reduction of shear forces is provided through good adhesion to the skin, high loft and lateral movement of the dressing layers |
