Is the waterproof band-aid really waterproof? What should I pay attention to when using waterproof band-AIDS?

Waterproof band-aid is not waterproof in all cases, and may not be waterproof in some cases, so there are some precautions when using waterproof band-aid:

1, you can't contact water for a long time with a waterproof band-aid. If the band-aid cannot be tightly attached to the skin around the wound, especially in special parts, such as fingertips, knees and elbows, it will become "waterproof".

2. When using waterproof band-aid, try to avoid contact with water, pay attention to observe and protect the wound, and replace the band-aid soaked in water in time.

3. Before using the waterproof band-aid, clean and disinfect the wound, tear the wrapping paper along the arrow direction, aim the absorbent pad at the wound, remove the left and right covering films in turn, and fix the position. When the surrounding parts are lightly pressed, the best waterproof effect has been achieved.

4. The waterproof band-aid has poor air permeability and cannot be used for a long time, so it needs to be replaced once in a while.
