HY-FYJ-01 is a small, lightweight, ultra-convenient notch negative pressure management system consisting of a dressing and a small negative pressure source (powered by 2 AA batteries). The system is single-use and the negative pressure source can last 35 days. The system can produce a continuous negative pressure of -60 MMHG, which acts on the incision, and the negative pressure causes the incision to heal. The system is intended for patients with incisions and wounds with low fluid seepage without the need for a large NPWT system. The semi-permeable "breathable" membrane in the dressing enhances its ability to manage seepage, thus eliminating the need for liquid storage tanks, and the portability of the system makes it ideal for patients transferred to community health care centers after surgery. The system can also be used in combination with filling dressings (specialty dressings) to treat slightly deeper wounds.

Medical grade PU material can cause ultrastructural strain in the tissue, stimulate fibroblasts to crawl and reach into contact with the wound, initiate negative pressure, and reduce the wound area. The strong permeability of PU material ensures that the exudate or necrotic tissue is sucked out smoothly and assembled freely. The self-equipped irrigation system can be used to accurately rinse the wound and administer medicine.

V.A.K. The latest generation of polymer composite PU+PVA, the perfect combination of polyurethane + polyvinyl alcohol, give full play to the advantages of the two materials, applied to various clinical wounds, greatly shorten the treatment cycle, improve the quality of treatment. Widely used in clinical trauma surgery, its honeycomb mesh of three-dimensional interworking structure can make the granulation tissue grow evenly and synchronously, so that the drainage is more smooth. Polyurethane: More reasonable mesh design, better permeability, can be shortened by 50% on the basis of PVA (polyvinyl alcohol) treatment time, because of its good permeability, so that the granulation tissue in a very short time to grow rapidly, in order to avoid granulation and material adhesion, add a layer of PVA between the polyurethane and the wound (polyvinyl alcohol) material, play its characteristics of not adhering to the tissue, the combination of the two play their own characteristics, so that the wound healing quickly. In addition, due to good permeability, in the case of the use of the same area of material, such as the use of PVA material requires two suction cups, in the use of PU material is only one suction cup can be used to ensure smooth drainage.
