Mechanism of action of iNPWT
副标题
● Continuous removal of wound exudate, Creating a moist wound environment
●  Sealing the wound, Isolating the wound from infection of externalorigin
● Reduction of interstitial oedema
● Consecutive improvement of microcirculation, stimulation of blood flow and oxygenation.
● Wound retraction, Stimulation of granulation tissue formation
● Removal of small tissue debris by suction,reduce wound infection.
Effect on the wound
● Reduction of the wound area due to negative pressure acting on the foam, pulls together the edges of the wound (wound retraction)
● Stimulation of granulation tissue formation in an optimally moist wound environment; in several situations even over bradytrophic tissue such as tendons and bone NPWT was able to stimulate granulation tissue formation
● Continuation of effective mechanical wound cleansing (removal of small tissue debris by suction)
● Effective biochemical reduction of the fluid concentration of wound healing-impairing proteases (such as elastase)—in the first days
● Reliable, continuous removal of wound exudate (and, consequently, fewer dressing changes) within a closed system
● Pressure-related reduction of interstitial oedema with consecutive improvement of microcirculation, stimulation of blood flow and oxygenation.

Handling
● Hygienic wound closure—bacteria proof wound dressing for sealing the wound so no external bacteria can enter the wound and the patient’s own wound bacteria are not spread. This is particularly important in the event of contamination with problematic bacteria, as in patients with meticillin-resistant Staphylococcus aureus (MRSA)-infected wounds. Thus, italso reduces the risk of cross-infections and development of resistance within the hospital
● Transparent dressing permits continuous clinical monitoring of the surrounding skin through the film with which the wound has been sealed
● Odourless and hygienic dressing technique; constant seeping through the dressing onto the patient’s clothing and bedding can be avoided, reducing demands on the nursing staff
● Reduction in the number of required dressing changes (only necessary every two to three days), which reduces nursing time requirements, particularly in patients with exudating wounds.
