Little knowledge about sterile cotton swabs

The doctor introduced that 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. If there are green spots, it is likely that you have bought a non-sterile cotton swab.

The non-sterile cotton swabs purchased from pharmacies in consumers' lives are not "medical cotton swabs", but can only be regarded as "life cotton swabs". They can be used to clean the skin and ears, but cannot be used for wound treatment. Buying 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.
