Background
Pressure sores refer to localized damage to the skin or underlying tissue, usually occurring at the carina, a site that is in contact with medical or other devices for prolonged pressure. Presenting as an open ulcer, possibly with pain. The strong or long-term pressure or pressure and shearing force can cause pressure sores, and factors such as micro-environments, nutrition, tissue perfusion and complications can also influence the tolerance capability of local tissues to the pressure and the shearing force so as to increase the risk of pressure sores. Pressure sores are a catastrophic complication of bedridden and elderly patients and are clinically characterized by complex, difficult to heal chronic wounds. The presence of pressure sores seriously affects the health, quality of life, and consumes a significant amount of sanitary resources.
The negative pressure sealing auxiliary wound closing (VAC) technology is a new wound treatment technology developed in more than ten years, and is a novel and mature treatment method for promoting wound healing by connecting a negative pressure suction device with a special wound auxiliary material, namely open-pore polyurethane foam dressing and intermittently or continuously generating pressure lower than atmospheric pressure at the wound to continuously remove liquid and infection sources of the wound, effectively seal and reduce cross infection and protect the wound environment; promoting perfusion of blood flow and granulation tissue growth to create a moist healing environment; the edema of the tissues around the wound is relieved, the material exchange between the wound surface and the wound periphery is enhanced, and the healing of the wound surface and the wound periphery are better combined together; stimulate the expression of various healing promotion genes and repair signals, promote the proliferation and the release of various growth factors and enzymes on the surface of the wound and the periphery of the wound, and promote the regeneration of epithelium, thereby promoting the better healing of the surface of the wound.
However, the cost of professional set VAC device is high, which limits the wide application of VAC device in clinic, especially in primary hospitals to a certain extent. A simple negative pressure sealing auxiliary wound closing device which is low in price, convenient to operate, simple to use and beneficial to popularization is needed.
