How to Use Band-Aids and Important Precautions


As its name suggests, a bandage is applied whenever there is a wound. It is one of the most commonly used topical medications in daily life, also known as a “hemostatic plaster,” and serves to stop bleeding and protect the wound. It consists of an elongated adhesive strip with a small medicated gauze pad embedded in the center. Due to its structural limitations, a bandage is suitable only for emergency treatment of minor wounds, providing temporary hemostasis and protection of the wound surface. However, it should be noted that prolonged use is not advisable; if left on for too long, the non‑breathable outer layer can cause the wound and the surrounding skin to turn pale and soften, increasing the risk of secondary bacterial infection and further complicating the healing process.
In general, for minor superficial abrasions, there’s no need to use a bandage; simply disinfect the wound with iodine or ethanol to help prevent infection. If you’re still concerned, you can apply a thin layer of gentian violet. After two to three days, the wound should form a scab and dry out. If the skin injury is relatively deep and you don’t have access to proper treatment, rinse the wound gently with clean water, then apply a bandage for basic protection—but keep it on for no more than one to two days. At the same time, seek prompt medical attention at a nearby hospital for professional disinfection to avoid unnecessary infection.
