Wound Care Test Methods

Microbial infection is the cause of the majority of chronic wounds. As such, wounds that are not clinically infected are almost certainly colonised. These types of chronic wound can therefore be deemed to be at risk of infection6.

Perfectus Biomed support companies who produce products for chronic wounds. We aim to help decrease patient pain and also decrease the number of amputations resulting from long term chronic wounds. We therefore hope to improve patient quality of life.

Perfectus Biomed can also help support your regulatory submission as well as your company research and development. We can also assist you in demonstrating the USP of commercially available products.

 

We have experience working with:

  • Wound dressings
  • Topical wound agents
  • Dressing removal agents
  • Irrigation solutions
  • Plasma devices
  • NPWT devices

We offer support with:

We offer a range of customised test methodologies which include:

  • Direct contact dressings testing, a method adapted from Gallant-Behn et al (2005).
  • Shake-flask method adapted from upon a method in Parsons et al (2005).
  • Bacterial barrier testing.
  • Viral/phage barrier testing.
  • CDC biofilm reactor model adapted for testing wound dressings based on ASTM E2871 and ASTM E2562.
  • Drip flow reactor model adapted for testing wound dressings based on ASTM E2647.
  • Porcine skin explant drip flow model based on ASTM E2647.
  • Wicking absorbency.
  • MMP modulation testing.
  • Dressing material strength testing – wet and dry.
  • Peel force testing.
