How Negative Pressure Wound Therapy Works
Negative Pressure Wound Therapy, also known as NPWT or wound VAC therapy, applies controlled vacuum pressure to a sealed wound environment using foam or gauze dressings connected to a suction pump.
The RH-450 therapy system promotes wound recovery through several mechanisms:
Removal of Excess Fluids
The vacuum pump extracts wound exudate, reducing swelling and preventing fluid accumulation that could delay healing.
Improved Blood Circulation
Suction pressure stimulates microcirculation around the wound site, promoting oxygen and nutrient delivery to damaged tissue.
Reduction of Bacterial Load
Sealed wound environments reduce contamination risks and help prevent infection development.
Promotion of Granulation Tissue Formation
Negative pressure stimulates cell growth and tissue regeneration, encouraging faster wound closure.
Edge Approximation
The therapy helps pull wound edges closer, supporting natural closure processes.
