A simple and sterile method for collecting wound fluid after negative pressure wound therapy.

The collection fluid of negative pressure wound therapy (NPWT) is a promising material for diagnostic and research of the wound. However, a standardized method for wound fluid collection has not yet been established. Only a few techniques have been described as drilling the canister or disrupting the suction port system. A simple and sterile method for collecting wound bed fluid directly after NPWT is demonstrated.
