This creation is about a composite negative pressure drainage foam dressing with an anti-adhesive support structure for a negative pressure wound therapy machine. Negative pressure wound therapy uses vacuum pumping to create a negative pressure environment at the wound to extract wound pus and infectious substances, and attract tissue fluid to maintain a moist treatment environment, and promote peripheral blood microcirculation to accelerate wound healing, but In the prior art, the problem of sticking between the tissue and the dressing is often avoided in such a process. Although, in order to cooperate with negative pressure wound therapy, many negative pressure wound care devices and dressings have emerged. Of course However, most of the current negative pressure wound care devices are applied to wounds with a large area on the flat skin. The efficiency of negative pressure drainage varies with the design of the drainage, and the tissue healing will also be different, especially between the tissue and the dressing. The problem of stickiness has caused great trouble in clinical application. Therefore, one of the aims of the present invention is to provide a negative pressure drainage foam dressing, in particular to provide a composite negative pressure drainage foam dressing having an anti-adhesive support structure.

This creation provides a negative pressure drainage foam dressing for reconstruction repair. In particular, the present invention relates to a composite negative pressure drainage foam dressing having an anti-adhesive support structure. According to the above object, a composite negative pressure drainage foam dressing having an anti-adhesion support structure, wherein the composite negative pressure drainage foam dressing comprises a drainage foam structure layer and a non-functional carbon-carbon structure a mesh layer, wherein the drainage foaming structure layer comprises a plurality of pores through which the internal environment is connected to the external environment; the non-functional carbon-carbon structural network layer comprises a first one which is suitable for skin bonding in clinical use. a surface, a second surface in close contact with the drainage foam structure layer, and a plurality of perforations connecting the first surface and the second surface, and forming an anti-adhesion support structure through the perforations. Preferably, the composite negative pressure drainage foam dressing is produced by a composite foaming or continuous bonding process.

Preferably, the drainage foam structure layer is selected from the group consisting of a polyethylene foam structure, a polypropylene foam structure, a polyurethane foam structure, a polyvinyl alcohol foam structure, a natural polymer foam structure, and a synthetic polymer. A group of foamed structures and combinations thereof. Most preferably, the drainage foam structure layer is a polyurethane foam structure.

Preferably, the non-functional carbon-carbon structural network layer is selected from the group consisting of polyethylene, polypropylene, graphite, carbon fiber, and combinations thereof, which can contact the skin to prevent sticking.

Clinically, the drainage foaming structural layer does not approach or contact the lesion containing the tissue fluid, and the tissue fluid must pass through the non-functional carbon-carbon structural network layer and pass through the perforation through the first surface to enter the drainage from the second surface. The foamed structural layer is joined to the negative pressure drainage therapy machine for tissue fluid attraction in an effective negative pressure environment, and the anti-adhesion support structure is provided during the process to avoid tissue sticking.

The spirit of the present invention will be clearly described in the following drawings and detailed description, and those of ordinary skill in the art will be able to change and modify the technology disclosed by the present invention after understanding the preferred embodiment of the present invention. It does not deviate from the spirit and scope of this creation.

First Embodiment - Composite Negative Pressure Drainage Foam Dressing with Anti-Adhesive Support Structure

A preferred embodiment of the present invention for constructing a cannulated negative pressure drain structure having a flexible arc profile adjustment body will be described with reference to FIG. According to the above-mentioned purpose of the present invention, the present invention provides a negative pressure drainage foam dressing for reconstructing and repairing. In particular, the present invention relates to a composite negative pressure drainage foam dressing having an anti-adhesive support structure. According to the above object of the present invention, a composite negative pressure drainage foam dressing 3 having an anti-adhesion support structure is provided, wherein the composite negative pressure drainage foam dressing 3 comprises a drainage foam structure layer 300 and a non-functional group. a carbon-carbon structural network layer 350, wherein the drainage foam structure layer 300 includes a plurality of foaming channels 310 through which the internal environment is connected to the external environment; the non-functional carbon-carbon structural network layer 350 includes a a first surface 353 for adhering to the skin during clinical use, a second surface 357 in close contact with the drainage foam structure layer, and a plurality of perforations 370 connecting the first surface 353 and the second surface 357 And forming an anti-adhesion support structure 330 through the through hole 370. For specific implementation applications, the composite negative pressure drainage foam dressing 3 is produced by a composite foaming or continuous bonding process. For application in clinically possible requirements, the drainage foam structure layer 300 can be selected from a polyethylene foam structure, a polypropylene foam structure, a polyurethane foam structure, a polyvinyl alcohol foam structure, and a natural polymer. A group consisting of a foamed structure, a synthetic polymer foamed structure, and a combination thereof. For best practice of the present application, the drainage foam structure layer 300 is a polyurethane foam structure (PU). Applying to clinically possible needs, the non-functional carbon-carbon structural network layer 350 can be selected from the group consisting of polyethylene, polypropylene, graphite, carbon fiber, and combinations thereof in accordance with clinical requirements to contact the skin to prevent sticking. For the best implementation of the present application, the non-functional carbon-carbon structural network layer is polyethylene (PE). Clinically, the drainage foam structure layer does not approach or contact the lesion containing the tissue fluid, and the tissue fluid must pass through the non-functional carbon-carbon structure network layer and pass through the perforation 370 through the first surface 353 from the second surface 357. Entering the drainage foaming structure layer, engaging with the negative pressure drainage treatment machine for tissue fluid attraction in an effective negative pressure environment, and providing the anti-adhesion support structure during the process, can effectively provide the composite negative pressure drainage foam dressing Anti-stick function to avoid tissue stickiness.
