Band-Aid is a kind of surgical medicine commonly used in our daily life. It is basically used by every family in our life. We can see that some of them are waterproof band-aids when you buy them . Are these waterproof band-aids really waterproof ? For this problem, many people will have a misunderstanding that it is possible to directly touch the surface of the water. This is wrong.
Is it waterproof for waterproof band-aids :
Waterproof bandages do not use waterproof band-aids for long periods of contact with water. If the band-aid is not tightly adhered to the skin around the wound, especially in special parts such as fingertips, knees and elbows, the waterproofing will not become "waterproof". The correct way should be to use water-resistant band-aids as little as possible in contact with water. Pay attention to observe and protect the wounds, and replace the water-soaked band-aids in time.
The outer layer of the band-aid is a plastic film coated with adhesive on one side, with pinhole-shaped holes on the top, and the inner layer is an island-type composite pad with strong absorption and non-stick wound, and two sheets of single-sided coated silicon paper; The sheet is sealed in a wrapper. It is a topical dressing that has hemostasis and protection. The plastic film is densely covered with small holes for good air permeability. It is used for small wounds, abrasions and other affected areas to help prevent the invasion of bacteria and foreign bodies and accelerate wound healing.
Precautions: Use waterproof plaster to minimize contact with water. Pay attention to observe the protection of the wound and replace the water-soaked plaster. Before using the waterproof plaster, clean and disinfect the wound. Follow the arrow to the broken wrapping paper. The cover film is removed from the fixed position and lightly pressed to the surrounding area to achieve good waterproof effect; the waterproof creation is poorly breathable and can be replaced during use.
In short, the idea that waterproof band-aids are really waterproof is not right, so don't think that sticking a band-aid can touch the water.
