Negative pressure tension reducing suture device for skin wound

The invention discloses a skin wound negative pressure tension reduction suture device, in particular to a skin wound negative pressure tension reduction suture device used in the field of skin wound healing. The invention provides a skin wound tension suture device with simple structure and convenient operation, which provides tension reduction while eliminating wound exudate in time, and can reduce the influence of tension stimulation on skin wounds. The tension reducing body, the pretensioning force reducing body is arranged on both sides of the negative pressure pipeline, the sealing film covers the pretensioning force reducing body to form a closed space, and the negative pressure pipeline seals the sealing film The inside of the formed closed space communicates with the outside. This application utilizes the negative pressure to deform the pre-tightening force decompression body, so that the final tension acting on the wound is reduced, and the scar restoration body is protected from tension stimulation. At the same time, the exudate in the wound passes through the negative pressure under the action of negative pressure. The tubing is drawn out, ensuring the cleanliness of the skin wound and reducing the chance of superinfection.
