Abstract

A multi-action wound dressing for accelerated wound healing by means of multi-therapeutic action is disclosed. The dressing comprises a porous sheet (101); two flexible sheets (102) having a first sheet (103) and a second sheet (104) attached to each other; multichannel conduits (105) or a plurality of single channel conduits; multichannel tubes (106), side adhesive tapes (107) and an optional wound contact layer (108). The porous sheet (101) includes a top planar surface (201), thickness (202) and a bottom uneven surface (203). The bottom uneven surface (203) lies on the surface of the woundand may have surface patterns (204). The pattern (204) may be wavy patterns and / or any other regular and / or irregular surface protrusion that allow intermediate gaps between wound surface and the bottom surface (203) of the porous sheet through which fluid can flow over the wound surface.

Description

technical field [0001] The subject matter described herein relates generally to wound healing and wound treatment therapies, and more specifically, to dressings for wound healing that are configured to evenly distribute negative pressure and fluid delivery at a wound site to enhance more favorable wound healing. A wide range of biological mechanisms. Background technique [0002] Wound healing is a natural biological process that occurs in four phases, beginning with hemostasis, followed by an inflammatory and proliferative phase, and concluding with a remodeling phase. Common chronic wound types are venous leg ulcers, ischemic wounds, diabetic foot ulcers, pressure wounds and acute wounds are traumatic wounds, postoperative wounds and burns. [0003] Wounds are classified as non-healing wounds if they do not heal in an orderly and timely manner. These wounds often do not close without intervention and sometimes resist healing interventions. A number of local and systemic...
