Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study aims to explore the differences in efficacy and cost-effectiveness between self-adhesive soft polysilicone silver ion foam dressings and traditional silver dressings in local infected wounds through a prospective randomized controlled study. The goal is to provide evidence-based medical support for clinical application, further shorten the wound healing time, and reduce the economic burden on the medical system and patients.
