Clinical Mechanism of Negative Pressure Wound Therapy
1.All-Directional Active Drainage
All-directional active drainage leads to the removal of bacteria culture media and toxic decomposition of wound injured tissue, reducing the organism tissue’s reabsorption of toxic decomposition. It can help avoid uncontrolled systemic inflammatory response syndrome (SIRS), block the pathological reaction chain and prevent the happen of multiple organ dysfunction syndrome (MODS).
2.Safe and Effective Closure of Wound Surface
The semipermeable membrane constructs a sealed environment, preventing the bacteria from entering into the wound surface, meanwhile ensuring the moisture vapor transmission from the skin to the outside, leading the wound to closure.
3.Promote Wound Healing
The controlled all-directional negative pressure provides power for active drainage, helping accelerate topical blood circulation and promote granulation tissue formation.
