Medical cotton swabs are divided into sterile and non-sterile packaging. Sterile cotton swabs are cotton swabs that are sterilized after packaging or are packaged after chemical disinfection treatment; non-sterile cotton swabs are cotton swabs that have not been sterilized. After they are supplied to medical institutions, they will be sterilized and then used for treatment.
The non-sterile cotton swabs we buy from pharmacies can be used to clean the skin and ears, but not for wound treatment. Buy non-sterile cotton swabs from a pharmacy, without the disinfection equipment and conditions in the hospital, if they are directly used for wound treatment, it is very likely that the wound will be infected and never healed.
Sterile cotton swabs are "bacteria" when they are opened, and should be thrown away after 12 hours.
