AI Technical Summary

Technical Problem

Existing wound patches are prone to squeeze the wound when applied to the wound, causing secondary pain and are not conducive to the breathability and healing of the wound.

Method used

A three-layer three-dimensional structure of the wound patch is adopted, including wound protection part, connection part, adhesive part and release paper. The wound protection part is woven with warp knitted three-dimensional structure fabric, with a hydrophobic outer surface layer, a hydrophilic inner surface layer and a spacer wire to form a buffered and breathable area.

Benefits of technology

While ensuring waterproof and breathable, the wound patch can form a good buffer protection space around the wound, avoid squeezing the wound, and provide a good breathable environment for wound healing.
