[0005] A sticky cloth portion forming a blocking portion along both sides of the wound and a reserved opening exposing the wound, a transparent biofilm adhesive layer covering and sticking both sides of the wound, the transparent biofilm adhesive layer covering the reserved opening, and the transparent biofilm adhesive layer is provided with equidistantly spaced grooves at the transverse midline position of the center of the reserved opening, limiting convex columns equidistantly distributed on both sides of the reserved opening, and a convex bead formed on the top of the convex column with a larger area than the top of the convex column, and a shrinkage seam formed on both sides of the length direction of the reserved opening. Aggregate chamfered parts;

[0006] The locking piece is in the shape of a long strip, and a plurality of expansion grooves are arranged at both ends of the locking piece in the length direction. The bottom of the locking piece has an adhesive layer connected to the transparent biofilm adhesive layer.

[0007] Furthermore, a reinforcing bonding layer is provided at the edge of the sticky cloth portion, the edge of the sticky cloth portion has a rough surface, and the sticky cloth portion is made of a textile material and has a waterproof layer.

[0008] Furthermore, the reinforced bonding layer is made of antibacterial material and has ductility.

[0009] Furthermore, the adhesive cloth part includes an anti-wrinkle base layer, an antibacterial layer arranged on the surface of the anti-wrinkle base layer, and an adhesive layer arranged below the anti-wrinkle base layer.

[0010] Furthermore, the bottom of the adhesive layer is provided with longitudinal lines and transverse lines, and the transverse lines and the longitudinal lines form a block-shaped adhesive part.

[0011] The utility model has the following beneficial effects:

[0012] The present application adopts a fitting method to cover the wound cutting path, and a plurality of locking plates for tightening are arranged above the incision perpendicular to the incision, which can cooperate with the sticky cloth parts on both sides for relative extrusion so that the incision can fit tightly together. This can ensure the healing speed and facilitate the operation without the need for suturing, which is more convenient. BRIEF DESCRIPTION OF THE DRAWINGS
