I believe that all of you have experience in volunteering and donating blood. Every time you draw blood, the doctor will take out two wooden cotton swabs from a evacuated packaging bag and let you press the wound. At this time, you will find carefully that the cotton swab given by the doctor seems to be different from the cotton swab we use everyday.

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

At present, there are two common types of cotton swabs in the market: civilian cotton swabs and Medical cotton swab (There are also some cotton swabs used for industrial purposes, so I will not repeat them here.) Because their appearance is very similar, if you do not understand them well, you are likely to use them "incorrectly", and ultimately fail to achieve the desired use effect.

That is to say, only by clearly distinguishing the difference between civilian cotton swabs and medical cotton swabs can you correctly select the type of cotton swab you currently need. First of all, their difference and identification method is external packaging. The packaging of medical cotton swabs will have obvious words "medical cotton swabs". The civilian cotton swab will put the use function or material on the package, such as "cosmetic cotton swab", "stick cotton swab", 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 undergone disinfection or chemical disinfection; Non sterile cotton swabs are cotton swabs that have not undergone disinfection treatment and need professional disinfection by medical institutions before use.

Therefore, when you are injured due to bumping or some other reasons, the wound should be treated with sterile medical cotton swabs. Non sterile cotton swabs can only be used after professional disinfection by doctors.
