Why can't medical mask be used twice?

 

1. Because the most important non-woven fabric in medical surgical mask is the meltblown non-woven fabric in the middle layer. Meltblown non-woven fabrics block viruses and bacteria through the barrier effect of fibers and the electrostatic adsorption of fibers. The fiber barrier and electrostatic adsorption of meltblown non-woven fabrics have a certain degree of saturation. When reaching a certain level, it no longer has the function of adsorbing pathogens. Therefore, the surgical mask is generally used for four hours and must be replaced. Up.

2. If we disinfect the used masks by boiling with water, spraying with alcohol or disinfecting with ultraviolet light, theoretically speaking, we can eliminate the bacteria and viruses sticking to the mask, but high-temperature boiling and alcohol spraying will both Destroy the fibers of the meltblown non-woven fabric, so that the function of the mask is reduced.

 

3. However, for patients with respiratory infectious diseases, if they must go to the hospital for treatment and there is no new disposable mask, they can consider reusing a disposable medical mask. The purpose of reusing masks is to reduce the possibility that these patients will spread droplets due to coughing or sneezing.

 

 

The difference between surgical mask and medical mask

"Medical surgical mask" is a medical mask commonly used in operating rooms and other environments where there is a risk of body fluids and blood splashes. It can block blood and body fluids from passing through the mask and contaminate the wearer. At the same time, the filtration efficiency of bacteria is more than 70%, but the filtration efficiency of particles Limited, and mostly rectangular design, the tightness with the face is not as tight as medical protective masks. Common medical surgical masks include strap type and ear hook type.

 

Ordinary medical mask

 

Ordinary medical masks have many names. Medical masks without the words "protection" or "surgical" in the name are all ordinary medical masks. This level of masks does not require blood barrier effect, nor does it have tightness requirements. Therefore, it is only used in general medical environments. Common common medical masks are mostly ear-hooks, and their appearance is similar to ear-hook surgical masks.

note:

 

The implementation standards of disposable mask and "medical surgical mask" are completely different. The thickness and quality of the filter layer between the two are obviously poor, and the final protective effect is even more different. The medical surgical mask has three layers of filtering. You can confirm whether there is YY0469-2011 on the package before purchasing. The masks that meet the YY0469-2011 "medical surgical mask" standard are the masks we need. The ordinary disposable mask is printed with YZB/ various factory logos.
