Science-mindedness means not knowing how much information science has, or not being able to do a few lines of complex arithmetic. Science means rational thinking, trying to understand and understand the unknown, and social and moral responsibilities come in its own way.
With the help of newspapers, the Internet or TV, we all now know that hospitals, hospitals and nursing homes are under Benazir’s pressure due to the global Corona virus. There is an urgent need to diagnose and cure a large number of dying patients on the one hand, and to ensure that the health workers who are in charge of this work are not affected. But there is a lack of masks and other personal protective equipment. When hospitals and health workers are in dire need, everyone is panicking over the lack of personal protective equipment. Each of us has a relative, or a friend working on the front-line, and we can’t just sit idly by. So, from scientists immersed in the complex theory of the mysteries of the creation of the world right now to designing smart phones to more comfortable engineers, housewives, or small business owners, everyone has jumped on the bandwagon – to help as much as they can. With this concerted scientific effort, it is possible to find many simple solutions to many difficult crises. And that is a reflection of true science.
The result of such a concerted effort is very easy to make a mask holder. Mask holder means to keep the mask seamlessly in the face. Many of us are now using protective masks to protect against airborne diseases. The American Society for Testing and Materials (ASTM), the National Institute of Occupational Safety and Health (NIOSH), and the Centers for Disease Control and Prevention (CDC) say that a special mask of the genus N95 is needed to protect against corona virus (COVID-19). The specialty of this mask is not only the ability to filter out 95% of the airborne particles. This mask sticks so well to the nose and mouth that there are no gaps and no germs or particles can enter the nose or mouth. Many homemade masks or simple surgical masks can filter out most of the airborne particles, but the gaps in the mask with the nose cannot close the pores. So while they are effective for common colds or dust or smoke, they are not as effective for deadly infectious diseases as the corona virus.
Some of the former engineers and designers of the world famous phone and computer company Apple were present at the event. Passing from reputed institutes like MIT, Cornell University, these technologists have come up with the idea of how to easily close the gaps in the mask with the nose and how to make it available to the general public. They showed that this problem can be solved by using three little rubber bands. Not only this, with the help of available masks like Surgical Masks, quality leak proof masks can be made close to N95 masks.
3 rubber bands
1 ASTM level surgical mask, or any home-made thick mask for general use, or two / three folded thick knitted handkerchief for Niden. If you don’t have a mask, you can start with an old vest or T-shirt. Look at the very last section.
Step 1:create a rubber band chain
Step 2:apply your surgecal mask.extend your mask verticaly.press in nose band.
Step 3:apply rubber band chain.check assembly for fit with finger feel test.
Use of masks and later versions
Dr. Biswajit Ghosh and his wife Shraddha Yadav of Salisbury, Maryland, on the recommendation of Science magazine, tested the mask holder made in this manner (see picture below). Although these rubber band masks are very effective in sealing gaps, we can learn two disadvantages from their response.
1) If this rubber band is worn for a long time, there is a lot of pressure on the back of the ear and the ear starts to ache; Oh
2) There is still a possibility of some leakage in the upper part of the nose. Mrs. Yadav suggested a solution to the first problem. He fastened the rubber band to the back of the head with two buttons, not behind the two ears. As a result, there is no pressure behind the ears.
If that is not possible in any case, then the members of the science journal suggest another alternative. According to this proposal we can work with five rubber bands instead of three rubber bands. In that case two rubber bands on the back of the head can be attached with a James clip or any other clip.
The second problem is the possibility of a leak at the top of the nose. This can be solved by tightening the mask with the nose with something like a small hairpin on the upper part of the nose. Usually the N95 type mask has a soft metal sheet, much like the soft metal sheet used to hold three leaking paper in a file folder . After wearing the mask, the metal sheet is chipped with two fingers and stuck to the nose.
One thing to keep in mind here. This simple mask is not only for corona virus, but can also be used at other times. For example, when going to school or college or going somewhere by bus, there is a lot of dust and smoke, or a cold or a cough, and you do not want to spread germs on someone else’s body. In that case, you can quickly take out a handkerchief and three rubber bands from your pocket and immediately make your own mask. In that case, just as other contagious germs will not be able to enter your nose or mouth, so someone other than you will be protected from getting unwanted gifts.
Making masks from scratch
There was talk of holding the mask for so long. If you want to make a mask from scratch, this is how it can be made. (This part is collected from COVID Gyan)
Take a vest or t-shirt. You can make two masks from one.
Cut a rectangular cloth measuring 11 inches x 9 inches, with two ropes to tie.
Fold the cloth in the middle like a rectangle.
Fold the top and bottom a little more and cut a little cloth to insert the rope at the four corners.
Insert the ropes in one direction and take them out in the other.
Pull the mask a little like yourself and fix it.
Wear the mask as shown in the picture. First tie the upper rope, then the lower one.
Wear the mask in such a way that there are no gaps around.
Here are a few rules to keep in mind:
(1) Once the mask is used, do not wash it and do not disinfect it. We will say to make more than one mask, the only advantage is that you can wear one when you wash and dry the other. If the mask gets wet, change it and wear another clean mask.
(2) Never touch the outside of the mask. First untie the lower rope and then the upper one.
(3) After removing the mask and washing your hands with soap, wash the mask well in hot soapy water and dry it in the sun or iron it hot before use.
