Beschreibung
Zusammenfassung:	The invention relates to a wound surface patch which contains a metal ion antibacterial agent, is used for closed negative pressure treatment of a wound surface and has antibacterial and tissue repair promoting effects, and a preparation method for the patch. The wound surface patch comprises a sponge layer, a negative pressure suction tube which stretches into the sponge layer, and a non-woven fabric combined with the sponge layer. The invention provides the negative pressure treatment wound surface patch which contains the metal ion antibacterial agent and ensures that negative pressure drainage is effectively implemented and antibacterial and tissue healing promoting comprehensive treatment effects are achieved simultaneously so as to improve the treatment effect of chronic and refractory wound surfaces such as diabetic ulcer and the like, and the preparation method for the patch.
