Wound healing is a difficult process, a process that follows the sequence of cell migration that leads immediately to repair and closure.
The order of healing requires a specific set of events, debris removal, infection control, clearance inflammation, angiogenesis, contraction, connective tissue matrix remodeling, and maturation.

Generally, chronic wounds are related to stress, trauma, vascular disease, or prolonged immobilization. Treating chronic, open wounds are variable and expensive. Fast healing of chronic wounds may result in decreased hospitalization and re-start of the function.
NPWT believed to promote wound healing through several measures including the removal of exudate from the wound to help build fluid balance, providing a moist wound environment, elimination of slough, decreasing the potential burden of wound bacteria, the reduction of edema, increase blood flow to the wound, increased growth factors, and promotions white blood cells and fibroblasts in the wound.
Negative pressure to bring the network together, pushing the network to keep it together through natural tissue adherence, which promotes healing.
Vacuum treatment is an effective alternative to conservative wound care and creates new chances for the treatment of various chronic and acute wounds.
Some of the proper application of NPWT acute wounds, partial- and full-thickness burns, surgical wounds and create surgical dehiscence, wound neuropathic or diabetic, venous or arterial insufficiency ulcers unresponsive to standard therapy, traumatic wounds, and pressure ulcers.
