Innovative Design of Masks And Anti-epidemic Products Under The Threat of Coronavirus
*How Does The New Coronavirus Attacks Human Body
The Covid-19 (SARs-CoV-2) virus enters the human respiratory tract in the form of particles and floats through the human nose and mouth until it passes over a long-shaped cell that has ACE2 (angiotensin converting enzyme) and serine protease TMPRSS2 receptors on the surface. The virus will immediately bind to this cell, attack its replication system, use the TMPRSS2 to activate the spike protein on the virus particle, then inserts it into the cell membrane through the Fusion Machinery of the spikes, which is open up now instead of folding up, while opening the outer layer of the cell membrane, the viral RNA and N protein inside the virus can slide into the long-shaped cell to help replicate itself until the viruses burst out and kill the cell, then start looking for other cells to invade.
Although the infected cells will send a warning to the immune system, trying to let it neutralize or eliminate pathogens, the virus can stop or intercept this warning, so that it has sufficient time to replicate before people starts showing symptoms.
*Which Cells Are Most Vulnerable to The New Coronavirus?
According to the research report that’s published in CELL magazine by the research team formed by MIT and Harvard University, the three most likely to be directly attacked by SARs-CoV-2 cells in the respiratory system and intestinal system, that has both ACE2 and TMPRSS2 cell types, including:
The above research used the single-cell RNA sequencing method to perform massive analysis of approximately 20,000 genes in human cells to find cells that express both ACE2 and TMPRSS2.
After the goblet secretory cells and ciliated cells in the nasal cavity are invaded, the virus will be replicated in large numbers, and there will be almost no symptoms within a week.
As the virus continues to replicate during this week, the infected person may spread a large number of viruses, and the symptoms can be just fever, dry cough, sore throat, headache or muscle pain. The second type of alveolar cells in the lungs are invaded, usually because the immune system of the infected person fails to fight the new coronavirus in the initial stage, causing the virus to travel along the trachea through the bronchus to the alveoli that’s rich in ACE2 receptor protein.
Type Ⅱ alveolar cell, also known as septal cell, can secrete surfactant, and the function of this compound is to prevent alveolar collapse, also to increase secretion during deep breathing, increase lung compliance and make lung expand easier. If the virus invades the type Ⅱ alveolar cells and cause the death of a large number of alveolar cells, but does not cause the immune system to respond, usually the symptoms are just poor compliance of the lungs. Before the patient finds out the abnormality, the virus can still proliferate in large numbers, and the patient can infect the surrounding area.
Even if the immune system is activated and begins to fight the virus at this time, it will produce a large amount of dead cells and mucus, which will destroy the blood oxygen exchange mechanism, and cause symptoms such as respiratory distress, severe cough and fever, and soon the patient will quickly enter a severe stage of infection. After the absorptive intestinal epithelial cells are invaded, it will cause various intestinal pathological symptoms. The new coronavirus has affected the micro-ecological environment of the human intestine, including constipation, diarrhea, flatulence, and various symptoms of impaired intestinal mucosal immune protection. The virus can also be spread through urine, feces, etc.
In addition to the above three cells that are susceptible to the invasion of the new coronavirus, there are other research units that have successively found cells with ACE2 receptors in the eyes, brain, nasal nerves, kidney, cardiovascular, and liver, and confirmed these cells have been attacked by the new coronavirus under the conditions of this epidemic. The symptoms include loss of the sense of smell and taste, conjunctivitis, epilepsy, brain inflammation, kidney metabolism problems, disseminated intravascular coagulation (DIC), myocardial damage, and elevated GPT/GOT liver index.
*The Public Health Crisis Around You
The possibility of community infection without specific symptoms is happening. Based on the above information, we can find that a wide range of symptoms may all be a warning of the infection with the new coronavirus. Most people lose their guard with mild symptoms, diseases that cannot be related to the new coronavirus, or even the possibility of infection without symptoms. Public health and the risk of large-scale infections are rapidly increasing, thus, wearing masks has become a normal scene when people cannot predict the infection. At least, the masks can protect people from being infected by the ubiquitous virus in the environment, and also prevent the infected person from spreading the virus to the surrounding environment.
*What Kind of Mask Is Actually Effective?
The flat medical masks that everyone wears in daily life are only been tested the barrier of the materials, but they didn’t realize that the frontal obstruction creates the risk of air flowing into the mask from both sides and up and down instead. In response to the current problems of the masks, ACTife has developed a long-lasting fabric material that can be recycled for many times. It uses an integrated weaving technique to innovate in mask technology, which is the fundamental solution to the public health problems that are mentioned above.
*For masks to be antibacterial, the virus must be eliminated within the very start.
Let’s think about the problems we are currently facing:
Let's take a look at the current flat medical masks on the market, which simply cannot meet the risk of potential community infections for three reasons:
The Mask Designed by ACTife Has Antiviral And Structural Protection
Antibacterial design: ACTife uses mask woven of ACT sputtering fibers to kill viruses and bacteria on the mask. There are two benefits:
Structural Protection Design of The Mask: ACTife Beautify Mask Adopts The Following Three Structural Designs:
Reusability And Long-term Effectiveness of Masks
The physical antibacterial technology makes the ACT sputtering has a high fastness, and will not be lost due to chemical reactions. At the same time, because the surface of the mask is free of bacteria, it is easy to maintain and will not cause cross contamination. ACTife beatify masks are free of living bacteria and viruses, so there is no waste disposal problem. You can use clean water or ACTife filter to wash and dry, and the product can be used for at least half a year.
ACTife Anti-epidemic Daily Necessities
ACTife also provides a series of daily necessities for epidemic prevention to remove possible viruses in the daily environment. These necessities include multi-size towels, phone pouch, gloves, socks, baby hat, utensil bags, air filters, water filters, and various antibacterial products that will be launched in the future.
