In daily life, we often choose to wear a mask, this is due to the increasingly serious environmental problem has been bothering us, in order to have a healthy body, to enjoy a better life and have to wear a mask.
As everybody knows, mask according to its use place is different, the use of material is different, the mask can also be divided into gauze masks, surgical masks, disposable masks, etc. , these are used as filter dust and bacteria in the air, so the filtration efficiency of surgical masks?
Here is to see together.
Complex surgical masks as important protective equipment, classification, scope and product protection performance also each are not identical, mainly including medical respirator, medical surgical masks and ordinary medical masks, etc.
In 2005 the ministry of health issued 'acute respiratory fever patients regulations require physicians in the process of accepts, with respiratory symptoms: (
A stuffy nose, cough, etc. )
, acute respiratory tract in patients with fever, should first provide a disposable surgical masks, avoid cross infection, in addition, the infectious diseases department and physician triage point to standard protective measures, all need to wear medical protective mask.
The fear is that some domestic current surgical masks because the reason such as the standard, quality process, does not have very good protection effect, and different types of surgical masks play a protective role also each are not identical, such as domestic medical non-woven masks for aerosol particles, only 20% of the protection efficiency;
Common 12 layer gauze masks the filtration efficiency is only 11% ~ 15%, completely unable to stop the artificial blood, staphylococcus aureus and escherichia coli F2 phage infiltration;
Activated carbon filter mask filtration efficiency is 11% ~ 17%, cannot stop the artificial blood seepage, but it can stop the staphylococcus aureus and escherichia coli F2 phage infiltration.
