With the prevalence of new coronavirus pneumonia in recent days, there have been cases of new coronavirus pneumonia infection in many places. With the advent of the Chinese New Year and the increase in population movements, it is more likely to cause the spread of this virus.
In the news 1 + 1 last night, Academician Zhong Nanshan has clearly pointed out that this new coronavirus pneumonia can be passed from person to person, that is, it can be spread through the respiratory tract. He also suggested that people wear medical surgical masks in crowded places to prevent infections.
So today, no matter online or outside pharmacies, masks are out of stock in many places. But there are still many people who do n’t know what kind of mask should be used. After all, there are disposable medical masks, paper masks, cotton masks, activated carbon masks, etc., which many people can’t tell.
As the subject asks, what is the difference between medical masks, nursing masks, surgical masks, and non-surgical masks?
In fact, there are not so many types of masks in hospitals, generally only disposable medical masks, medical surgical masks and medical protective masks. So, how to distinguish between disposable medical masks, medical surgical masks, and medical protective masks? What role do they each play?
1. Distinguish from the packaging
Generally, these three masks have different technical standards. The "disposable medical mask" is (YY / T0969-2013), and the "medical surgical mask" is (YY0469-2011). The "medical protective mask" is (GB19038-2010) . You can judge which type of mask the product belongs to by checking the execution standards marked on the product's outer packaging, and the respective names will be written on the packaging.
2. Different mask shapes:
Disposable medical masks and medical surgical masks are rectangular in shape, with ear-wraps and straps. The vast majority of medical protective masks are duck-billed, which is a good distinction.
3. The performance is different:
These three types of masks can filter bacteria, but they are different in water resistance and particle filtration efficiency. First of all, disposable medical masks do not have performance requirements for both water resistance and particle filtration efficiency, while medical surgical masks and medical protective masks have requirements. Secondly, the waterproof performance of medical surgical masks is higher than that of medical protective masks, which can prevent the infection of doctors caused by the splashes of blood and body fluids generated during surgery.
Finally, medical protective masks must also have the main functions of surgical masks, including bacterial filtration efficiency and the function of blocking liquid splashes with pressure, as well as respiratory protection, that is, to protect the wearer's breathing safety. Moreover, the particle filtering efficiency of medical protective masks is higher than that of medical surgical masks.
What does each of these three masks do?
First of all, disposable medical masks are only suitable for blocking contaminants exhaled by the operator's mouth and nasal cavity during general diagnosis and treatment operations, that is, when there is no invasive operation, clinical hospital staff generally wear such masks at work. Can basically meet the needs of our ordinary people.
Secondly, medical surgical masks are suitable for wearing during surgery, laser treatment, isolation and dental or other medical operations, as well as airborne or droplet-borne diseases or wearing because they have good waterproof performance and particle filtration efficiency; they are mainly used to meet hospital operating personnel use.
Medical protective masks have good particle filtration efficiency and can effectively filter viruses, so they are suitable for occupational protection when medical personnel are exposed to patients with airborne and droplet-borne diseases or when they are in contact with infectious microorganisms.
For the prevention of this new coronavirus pneumonia, which mask should I choose?
In fact, from the interview of Academician Zhong Nanshan, it has been explained that for the prevention of the new coronavirus pneumonia, only medical surgical masks need to be worn in daily life, and there is no need to wear medical protective masks. If you are in contact with a patient who has been infected with the new coronavirus pneumonia, you need to wear a medical protective mask, such as a N95 mask.
