Negative pressure wound therapy is considered to be an effective treatment for promoting wound healing. Negative Pressure Wound Therapy (NPWT) technology is an advanced wound therapy technology developed in recent years, which promotes wound healing mainly by a low negative pressure (typically-55 mmHg to 175 mmHg). When the negative pressure suction acts on the cell membrane and expands and twists the cell membrane, the cells can immediately transmit a 'damage of the cell membrane' signal to the cell nucleus, so that a large amount of pre-healing growth factors including vascular proliferation factors are secreted by the cell nucleus to stimulate tissues of a wound surface to generate more new blood vessels and accelerate the healing of the wound surface.
Negative pressure wound therapy is to place the wound bed of the wound surface in a closed and low oxygen environment, which is easy to cause secondary wound anaerobic bacteria infection, thus providing the viewpoint of oxygen supply negative pressure therapy.
