I believe everyone has the experience of being a volunteer and donating blood. Every time after the blood is drawn, the doctor will take out two wooden cotton swabs from a vacuum packed bag and let you press the wound. At this time, you will find that the cotton swabs given by the doctor are somewhat different from those we use daily.

In life, many small friends often buy some cotton swabs from supermarkets or pharmacies and keep them at home. They are mainly used for daily wound treatment or some liquid medicine application due to bumps or accidents. However, it is worth noting that not every kind of cotton swab can be used to wipe the wound or apply the medicine.

At present, there are two kinds of cotton swabs commonly used in the market: civilian cotton swabs and medical cotton swabs (some cotton swabs are for industrial use, and will not be described here). Because their appearance is very similar, if you do not know them well, you may "use them incorrectly" and ultimately fail to achieve the desired use effect.

In other words, only by clearly distinguishing the difference between civilian cotton swabs and medical cotton swabs can you correctly choose which type of cotton swabs you currently need. First of all, the difference and identification method is the outer packaging. There will be obvious words "medical cotton swabs" on the packaging of medical cotton swabs. While civilian cotton swabs will put the use function or material on the package, such as "makeup cotton swabs", "wooden swabs", etc.

In addition, medical cotton swabs are divided into sterile medical cotton swabs and non sterile medical cotton swabs. Sterile cotton swabs are cotton swabs that have been sterilized or chemically sterilized; Non sterile cotton swabs are cotton swabs that have not been disinfected and can only be used after professional disinfection by medical institutions.

Therefore, when you are injured due to collision or some other reasons, you should use sterile medical cotton swabs when treating the wound. Non sterile cotton swabs can only be used after professional disinfection.
