Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a skin-fitting device for wound healing that is easy to fix. Background Art

[0002] In the prior art, in order to evenly and symmetrically adhere the patch to the skin on both sides of the wound or scar, the spines on the patch are usually adjusted to gradually reduce the gap in the middle and the excess exposed spines are cut off.

[0003] Among the many existing technologies, Chinese patent CN208065220U discloses a zipper-type needle-free suture device, including a double-sided adhesive layer, a fixing component and a locking component. The double-sided adhesive layer is separated and arranged in parallel on the left and right and is in the shape of a long strip. The double-sided adhesive layer on the left is provided with a plurality of fixing components arranged at equal intervals, and the double-sided adhesive layer on the right is provided with a plurality of locking components arranged at equal intervals. The locking component includes one upper and one lower locking components connected to each other. The fixing component includes a fixing seat and a drawbar strip. Two horizontally parallel drawbar strips are provided on the fixing seat. One end of the drawbar strip is fixedly connected to the fixing seat, and the other end passes through the locking component and extends from the locking component. The tail end of the extended part is provided with a handle ring for pulling the drawbar strip.

[0004] However, the patent application requires too many drawstring strips to be pulled, and the degree of wound compression varies and is difficult to control. After the suture is pulled, no medicine is applied on the surface, resulting in insufficient wound recovery.
