How to choose dust-free purification cotton swabs
Nowadays, cotton swabs are used more widely. Cotton swabs are needed in various fields of use, but there are also many types of cotton swabs. Cotton swabs such as dust-free purification cotton swabs are mostly used in dust-free environments. So in the use of purification cotton swabs , how should you choose?
First of all, most cotton swabs sold in supermarkets have not been sterilized and are suitable for ordinary cleaning work such as makeup. If you are treating wounds, it is best to use sterile cotton swabs, such as those prescribed by the hospital or purchased from pharmacies. Secondly, among the sterile cotton swabs, one is wrapped in yellow paper. This kind of cotton swab has been sterilized by high temperature and high pressure. If it is unopened, it can usually be kept good for two weeks. The weather in the south is humid, so wrapping paper is susceptible to moisture and the shelf life may be shortened to about a week. The other is sterilized by ethylene oxide gas, packed in plastic bags or sealed in boxes, and has a shelf life of about 2 to 3 years.
Precautions for dust-free purification cotton swabs
1. After the sterile cotton swab is used up, the outer package needs to be sealed. Once the outer package is opened, if stored properly, it can remain sterile for 24 hours. If it exceeds 24 hours, it will no longer be sterile due to contamination by bacteria in the air. bacteria.
2. Disinfection only kills pathogenic microorganisms, while sterilization can kill all bacterial seeds, that is, spores. Cotton swabs contain bacterial spores, and disinfectant cannot do anything about them, and even the disinfectant may be contaminated. At this time, not only will the disinfection effect not be achieved, but it may cause infection, so cotton swabs that are no longer sterile must not be used on the wound.
3. Do not place cotton swabs in the ear canal. Using cotton swabs to remove earwax may cause the earwax to fall off from its original place and pile up, making it easier to penetrate into the ear canal and block the ear, causing pain, hearing problems, tinnitus or dizziness. If necessary, medication may be required to solve the problem. A cotton swab may penetrate too deeply and cause the eardrum to rupture.
