The present invention proposes a negative pressure tension reducing suture device for skin wounds, in particular a negative pressure tension reducing suture device for skin wounds in the medical field. The present invention is a negative pressure tension-reducing suture for skin wounds that is simple in construction and easy to operate, capable of draining wound exudate in a timely manner and reducing the effect of tension on skin wounds. Providing equipment. A negative pressure tension reducing suture device for a skin wound includes a negative pressure support, a sealing film, and a deformable member. The deformable member is disposed separately on both sides of the negative pressure support, and the sealing film is deformable. The member is covered to form a closed space, and the negative pressure support connects the inside and the outside of the closed space formed by the sealing membrane. In the present invention, the deformable member deforms under negative pressure to reduce the tension on the wound, while at the same time draining the wound exudate, ensuring that the wound is clean and reducing the possibility of co-infection.本発明は、皮膚創傷のための陰圧張力軽減縫合装置、特に、医療分野における皮膚創傷のための陰圧張力軽減縫合装置を提案する。本発明は、創傷の滲出液を適時に排出し、かつ皮膚創傷に対する張力の影響を低減することのできる、構造が単純でありかつ操作が容易である、皮膚創傷のための陰圧張力軽減縫合装置を提供する。皮膚創傷のための陰圧張力軽減縫合装置は陰圧支持体と密封膜と変形可能部材とを含み、変形可能部材は陰圧支持体の両側に分離して配設され、密封膜は変形可能部材を被覆して閉鎖空間を形成し、陰圧支持体は密封膜によって形成される閉鎖空間の内側と外側を接続する。本発明では、変形可能部材は陰圧下で変形して、創傷に対する張力を低減し、同時に創傷の滲出液を排出し、創傷が清潔であることを確実にし、重複感染の可能性を低下させる。
