Abstract
The utility model provides a negative pressure drainage sponge dressing and surface of a wound device thereof, including main part sponge and sponge dressing strip, sponge dressing strip is the right angle triangular prism, sponge dressing strip centers on the main part sponge completely, the utility model discloses a negative pressure drainage sponge dressing can make adhesive film can laminate dressing and sponge completely, avoids causing the skin uplift phenomenon that contains the water liquid that dressing edge epidermis exposed and arouses.
Description
Technical Field
The utility model belongs to the technical field of the dressing and specifically relates to a negative pressure drainage sponge dressing and surface of a wound device thereof.
Background
Negative Pressure Drainage Wound Therapy (NPWT) is also called Vacuum Assisted Closure Therapy (VAC), and Negative Pressure Sealing Drainage (VSD). The application method comprises covering a layer of dressing on the wound surface, embedding drainage catheter in the dressing, sealing the dressing and the wound surface with adhesive film, sucking out gas in the dressing by mechanical means to form certain negative pressure on the wound surface, and sucking wound exudate from the drainage catheter into a drainage bottle outside the body. The negative pressure drainage can timely discharge the seepage, the necrotic cells, the tissues and the hemorrhage out of the body, destroy harmful biomembranes generated by bacteria, and the surface negative pressure can stimulate the growth of granulation tissues and promote the healing of wound surfaces. Negative pressure drainage wound treatment techniques are currently widely used on a variety of acute and chronic wounds, for example: fracture, burn, skin grafting, chronic ulcer, pressure ulcer (pressure sore, bedsore), diabetic foot, surgery, etc. The negative pressure drainage wound surface treatment technology can promote wound surface healing, especially many difficult-to-heal wound surfaces, shorten hospitalization time, relieve the pain of patients, improve the life quality of the patients, generally reduce treatment cost, and has obvious social and economic values.
The dressing used for the negative pressure wound treatment at present is mainly made of polyvinyl alcohol PVA and polyurethane PU materials, and the dressing is more commonly used at home. The dressing has a certain thickness and rigidity, and is rectangular in cross section and vertical in edge. Therefore, when the dressing is sealed by the adhesive film, the edge of the sponge is provided with a triangular gap because the adhesive film cannot be attached to the vertical edge, and the skin is exposed in the gap. The skin of the part is in a negative pressure environment outside the corium, the pressure is reduced, the pressure difference exists between the inside and the outside of the corium, and the exposed part forms a skin bulge containing water liquid after a long time. The swollen skin containing water can break, causing infection or leaving scars.
