[0002] An infected wound refers to a pathological condition in which pathogenic microorganisms invade and multiply the damaged part of the skin or mucous membrane, causing inflammation and damage to the local tissue. The recovery of an infected wound refers to the process of gradually restoring the normal structure and function of the wound that has been invaded by pathogenic microorganisms and caused an inflammatory response through a series of medical intervention measures.

[0003] Existing infected wound recovery is usually achieved through negative pressure wound treatment technology, which uses porous foam dressings and sealing films to cover the wound, and then uses negative pressure suction to drain to promote wound healing. However, the current method can only achieve drainage. For complex or large-area wounds, it is impossible to flush and drain different parts of the wound at the same time, which can easily lead to blind spots in treatment, causing some areas to be untreated and cause infection, affecting the drainage effect and the recovery process, and is inconvenient to use.

[0004] Therefore, it is necessary to design an infectious wound recovery auxiliary device that can adjust the angle of the rotating ring to flush and drain different positions of the wound, increase the range of flushing and drainage, prevent infection caused by untreated areas, improve the efficiency of flushing and drainage effects, and be flexible and convenient to use.
