Wound Care

It has been estimated that the majority of chronic wounds result from some level of microbial infection. Those that are not clinically infected are almost certainly colonised and therefore can be deemed to be at risk of infection6.

By supporting companies who produce chronic wound care products we aim to help; decrease patient pain, decrease the number of amputations resulting from long term chronic wounds and increase patient quality of life.

Perfectus Biomed can help support with regulatory submissions, your company research and development and assist you in demonstrating the USP of commercially available products.
