[0002] Chronic non-healing wounds are a global health problem, and long-term non-healing wounds mean a greatly increased risk of infection, and even serious consequences such as amputation. Diabetic foot sores are a kind of chronic non-healing wounds, and when treating diabetic foot sores, in addition to controlling blood sugar, blood pressure, blood lipids and other systemic factors, attention should also be paid to the standardized treatment of local wounds, including anti-infection, debridement, use of wet dressings, closed negative pressure wound therapy, autologous platelet gel therapy, and wound biological agent (cytokine) therapy.

[0003] The band-aid can compress and stop bleeding, protect the wound, prevent infection, and promote healing, and has the advantages of small size, simple use, convenient carrying, good air permeability, reliable efficacy, and high patient compliance. However, the therapeutic effect of conventional dressings on chronic non-healing wounds is not ideal, and because the adhesive tape of the band-aid is not breathable, prolonged use can cause the wound and the skin around the wound to turn white and soft, leading to secondary bacterial infection and further worsening of the wound.

[0004] Nowadays, there are many new technologies for chronic wound healing, such as micro-current stimulation technology, which has been proven to promote cell proliferation, improve blood circulation, reduce inflammation, stimulate nerve regeneration, accelerate the epithelialization process of the wound, promote skin drug absorption, kill bacteria, promote blood accumulation, and form new blood, etc. However, the current band-aid structure is relatively simple, for example, the breathable band-aid disclosed in CN202120918661.8 has the advantages of reducing the covered area of the skin and good air permeability, but the therapeutic effect is limited, and the simple structure cannot meet the needs of promoting chronic wound healing.
