Perfectus Biomed support companies who produce products for chronic wounds by providing materials, planktonic and biofilm testing.
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 wounds can therefore be deemed to be at risk of infection.
We support the research and development projects of companies who create products for chronic wounds. We aim to help decrease patient pain as well as the number of amputations resulting from long term chronic wounds, with the hope to improve patient quality of life. We carry out safety and efficacy testing to ATCC, BS EN and ASTM standards. Examples include AATCC Test Method 100, BS EN ISO 11737-1 and ASTM E2149. GLP compliant testing is also available.
Perfectus Biomed can also help support your regulatory submission and 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
