In daily life, it is inevitable to encounter accidents such as scratches and scratches on the skin. In addition to disinfecting the wound, bandages will also be chosen for sterilization, hemostasis, and other protection of the wound. A small wound, paired with a small band-aid, can stop bleeding in a timely manner, accelerate healing, and once applied to the hand, gives people a full sense of security! So, does a small band-aid contain medication? How often does it need to be replaced with a new one? Is it really possible to apply any kind of wound? Let's take a look at the common misconceptions when using band-aids. Myth 1: Band-Aids=Wound Healing Medicine Band-Aids generally consist of three parts: a pad, a back patch, and a protective layer that come into contact with the wound. The protective layer is removed when used, with a rubber paste adhesive on the back for fixation. The pad is made of elastic fabric and generally does not contain drugs or other ingredients. It is used to stop bleeding by applying pressure. There are two types of medicated bandages: Yunnan Baiyao bandages, which contain confidential pharmaceutical ingredients and have hemostatic, anti-inflammatory, and wound healing effects; Benzalkonium chloride patch, containing benzalkonium chloride as a cationic surfactant broad-spectrum fungicide. All others are drug free bandages. Band-aids are mainly used for the care of shallow wounds such as small wounds, abrasions, cuts, etc. with neat and clean incisions, minimal bleeding, and no need for suturing. When choosing band-aids with medication, it is important to pay attention to whether you have any drug allergies and choose according to your needs. Myth 2: Bandaids are something that needs to be noted before, during, and after use. It's not just about simply using them. Before use: 1. It is recommended to purchase medical band-aids with a formal approval number; 2. Choose a bandage with an outer layer made of fabric, which has poor breathability and is not conducive to wound healing; 3. If there is dirt such as mud inside the wound, clean and disinfect it before use. When using: 1. After opening the seal, avoid touching the middle pad with your hands to prevent infection; 2. The bandage should not be too tight, as it may cause poor blood flow at the wound and slow healing; 3. After applying, avoid getting wet. Waterproof bandages are not absolutely waterproof. After use: 1. It cannot be used for a long time, and should be replaced at least once a day. If it gets wet or contaminated, it should be replaced in a timely manner; 2. If there is a burning sensation in the area of use, it should be stopped immediately. If the symptoms are severe, it is necessary to seek medical treatment in a timely manner; 3. Avoid squeezing the wound with your hands to prevent it from cracking. Myth 3: Bandaids=Universal patches. Bandaids are not universal patches and can be applied in any situation. Bandaids should not be used in these six situations: 1. Small and deep wounds are prone to infection with tetanus and form pus, which is not conducive to the discharge of secretions; 2. Injuries caused by animal bites or insect stings, where venom and bacteria are prone to accumulate or spread within the wound; 3. Burns and scalds can easily rupture the skin, exacerbating infection; 4. Wounds with skin boils and swelling are prone to bacterial growth and reproduction, which is not conducive to pus drainage; 5. Large, dirty, and bleeding wounds should be promptly treated at the hospital; 6. Individuals who are allergic to medication on adhesive tape and pads. It seems that as a "star product" in the family medicine box, the small band-aid is not a "universal patch". It is recommended that everyone strictly grasp the indications when using it, observe the wound situation in a timely manner during use, and do not apply it casually or for a long time. Only when used correctly can the wound heal faster. Beijing Harmony Home
