The classification of medical masks that medical staff must see
Due to the COVID-19 epidemic, we can be said to be "forced" to learn about various types of masks. In the past, we non-medical staff hardly wore masks, and even thought it was weird to wear masks on daily trips. Now we are accustomed to wearing them every day. The epidemic in China is basically under control, but daily protection is still needed. As medical staff who often serve patients, there are three categories of medical masks they wear.
Standard classification of medical masks, what are the classifications of medical masks? A medical mask is composed of a mask body and a tension band. The mask body is divided into three layers: inner, middle and outer. The inner layer is made of skin-friendly material, the middle layer is the isolation filter layer, and the outer layer is a special material antibacterial layer. This high-efficiency medical mask has strong hydrophobic and air permeability, has a significant filtering effect on small virus-carrying aerosols or harmful dust, has a good overall filtering effect, and the materials used are non-toxic, harmless and comfortable to wear.
There are nice medical masks in our company, such as bandage surgical face mask, protective 3 ply IIR surgical disposable medical face masks, EU EC medical masks and so on. Now, i'd like to introduce the types for you.
Common medical masks are disposable non-woven masks, gauze masks, and special anti-virus masks
1. Disposable non-woven mask
Disposable non-woven masks have more than three layers to isolate bacteria and dust, and they are safe and reliable for one-time use without the risk of secondary infection.
If you are one of the manufacturers who need to wear masks, such as wall paint glitter powder manufacturer, workshop workers use double sensors conveyor needle metal detector detecting metal impurities, workers make bulk yellow automotive masking tapes, cut the bevelled surface subway tile etc. You may need a disposable non-woven mask to prevent micro-particles from entering the body.
2. Gauze mask
The most commonly used type of mask, gauze masks are widely used in the fields of medical care and scientific research. For example, biodegradable packaging adhesive and other fields of biological environmental protection or other scientific research.
3. Anti-virus mask
It is mainly made of special materials with a filter layer in the middle. Generally, the filter layer is made of activated carbon felt or melt blown cloth. It has the effect of sterilization and sterilization.
According to performance characteristics and scope of application
1. Disposable medical masks
The structure of ordinary medical masks is rectangular, which is mainly used in ordinary diagnosis and treatment environments or scenes with low population density;
Comply with the relevant registered product standards (YZB), generally lack the filtration efficiency requirements for particles and bacteria, or the filtration efficiency requirements for particles and bacteria are lower than medical surgical masks and medical protective masks.
2. Medical surgical masks
Medical surgical masks, similar in structure to disposable medical masks, have the function of preventing blood and liquid, and are mainly worn by medical staff in invasive operating environments;
(1) Purification productivity: Under the condition of air circulation (30 ± 2 )L/min, the filtration productivity of sodium chloride aerosol with wind resistant average size (0.24 ± 0.06 )μm is not lower than 30%;
(2) Bacterial purification efficiency: Under specified ailments, the filtering performance of Staphylococcus aureus spray along with an average particle dimension of (3 ± 0.3) μm is actually certainly not lower than 95%;
(3) Respiratory protection: Under the health condition of filtration performance and also circulation speed, the inhalation resistance does not exceed 49Pa, and the breath resistance performs not go beyond 29.4 Pa.
3. Medical protective masks
Medical protective masks always with a higher level of protection are mainly worn by medical staff in special areas of isolation wards, isolation intensive care, and fever clinics.
(1) Filtration efficiency: Under the ailment of air circulation (85 ± 2 )L/min, the purification performance of sodium chloride aerosol with wind resistant average diameter (0.24 ± 0.06) μm is actually not less than 95%, which remains in line with N95 (Or FFP2) as well as above.
(2) Inhalation protection: Under the above flow ailments, the breathing resistance performs not go over 343.2 Pa (35mmH2O).
We passed EU EC standard test, we have majorly exported them to North America, Europe and other countries. You can wholesale EU EC Medical masks from our company without any worry.
To sum up
In general, medical masks are usually divided into three types: disposable general medical masks, medical surgical masks and medical protective masks. The simplest and lowest level is the disposable ordinary medical mask, which is used in ordinary medical environments, such as when nurses give patients infusions or perform general medical operations. Medical surgical masks and medical protective masks generally have three layers, which have been specially treated. The outer layer can prevent the penetration and splashing of blood, body fluids, and microorganisms, and the inner layer that contacts the body surface can prevent penetration and waterproofing. The layer is used to filter viruses and microorganisms.
Consumers should proceed from their own actual situation when purchasing, and choose a mask that is suitable for them and at the same time can effectively protect against bacterial dust.
As a mask manufacturer, we suggest that the best use time is 4 hours, and you need to replace it after 4 hours. If there is contamination, such as splashing on the outer surface or staining or wetting of the inner surface during operation by an invasive operator The next will be discarded. When used by the general public, it is recommended to carry out ordinary drying to extend the use time according to the use time and use scene, to avoid our excessive use and excessive protection, and avoid white pollution.
It is recommended that you need to wear a disposable mask when you travel now, although it is only 20 minutes from your starting point to your destination by riding a lithium electric bike. If the air is not good, it is best to wear it.
