Investigational Device: V.A.C. VERAFLO™ Dressing Kit
NPWT consists in applying topical sub-atmospheric pressure to a wound that is covered with V.A.C. VERAFLO™ Dressing, sealed with drape and connected by a tube to a suction pump applying -125mmhg pressure with a drainage collection system. Instillation and dwell of a topical wound solution in the wound bed cycled at set intervals of 10 minutes every 3.5 hours without negative pressure applied. The target wound for each subject in both groups will be treated for up to 14 days or until deemed ready for closure by the investigator (whichever occurs first).
Comparator Device: Negative Pressure Wound Drainage Material
A Negative pressure wound drainage material manufactured by Guangdong Shuangling Pharmaceutical Co., Ltd. (with unspecified pressures ranging from -150 to -380mmHg) was selected as the control group treatment device, which can apply the NPWT therapy with wall suction. This control device is widely used in clinical institutions in China to deliver NPWT. The target wound for each subject in both groups will be treated for up to 14 days or until deemed ready for closure by the investigator (whichever occurs first).
