INDEX Reasons for our Selection The related product Search Report Our future Plans Q & A I will explain the reasons for our selection, the related product, related patent, and our plans.

Reasons for our Selection Environmental problem of china One of the most obvious problems that China faces today is air pollution, in particular, fine dust. As you can see in the image above, the people of China have to wear inconvenient masks on a daily basis to avoid fine dust

Reasons for our Selection Environmental problem of china These pictures were taken in Beijing. As you can see in these pictures, even in bright daylight, due to fine dust, the day looks as if it is the evening.

Reasons for our Selection Environmental problem of china For many recent years, with the problem of air pollution, Chinese people have desired better health. The department of Chinese statistics showed that out of the 740 million laborers, 250 million laborers required to wear mask. As a result of this desire, the size of the mask market in China is expected to increase to be worth ¥ 5,300 million in 2018. In the graph, the horizontal dotted-blue line represents the amount of air pollution in a smoking area. And the blue curve represents the maximum amount of air pollution in Beijing. For many recent years, Chinese people have desired better health. The Department of Chinese Statistics showed that out of the 740 million laborers, 250 million laborers are required to wear masks. According to the EIS China, 중국 환경산업 정보망 in Korean, As a result of this desire, the size of the mask market in China is expected to increase to be worth 5,300 million yuan, 53억 위안 in Korean.

Reasons for our Selection Easy breathing particulate mask This is why we chose to combine a particulate mask with a nasal cannula.

Reasons for our Selection Why we do not select the oxygen mask Fine dust enter through the small holes in oxygen mask. In order to flush out 𝐶𝑂 2 , Oxygen mask require more than 5 LPM (Litter per minute) of air to enter. In order to carry out such a task, Oxygen masks require a big battery and oxygen-providing devices. Now I will explain why we did not simply choose oxygen masks. People commonly think that oxygen masks are better devices than the particulate masks. But, oxygen masks have limitations. First, there are small holes in oxygen mask, so fine dust enter through the small holes in oxygen mask. And CO2 remains in the oxygen mask when user breathes. In order to flush out CO2, oxygen masks require more than 5 LPM of oxygen to enter. And in order to carry out such a task, oxygen masks require a big battery and oxygen-providing device, which is inconvenient, if not impossible, to carry around.

And in order to carry out such a task, oxygen masks require a big battery and oxygen-providing device, which is inconvenient, if not impossible, to carry around. Oxygen flow at a 5 LPM.

Reasons for our Selection Why we do not select the oxygen mask In order for an oxygen mask to function properly, Oxygen masks require Humidifiers. In addition, in order for an oxygen mask to function properly, oxygen masks require humidifiers, which are devices that provide humidity to air. This is also inconvenient for people to carry around.

Reasons for our Selection Why we select the particulate mask & the nasal cannula We chose the particulate mask and the nasal cannula

Reasons for our Selection Why we select the particulate mask & the nasal cannula The particulate mask does not require the flow rate of over 5 LPM to flush out 𝐶𝑂 2 This mask provides air only when the person needs to consume oxygen. So, Nasal cannula – attached particulate mask doesn’t require a big battery, a humidifier, and a big oxygen providing device. because this mask does not require the flow rate (of over 5LPM) to flush out CO2. if you are not a patient, you don’t need 5 LPM when you breathe. We only need 1~2 LPM to breathe. And this mask provides air only when the person needs to consume oxygen. Actually, we only need small amount of air when we inhale. In this graph, the yellow rectangular represents the time that people needs to consume oxygen. So, nasal cannula - attached particulate mask doesn’t requires a big battery, a humidifiers, and a big oxygen-providing device.

The related product Portable Oxygen concentrator Name Inogen G3 Dimensions L/W/H : 22.2 / 7.6 / 18.4 (cm) Weight 2.19 kg Battery Duration Up to 4 ~ 5 hours Oxygen Concentration 90% - 3% / +6% at all settings Price $ 2,665 (약 310만원) Portable Oxygen concentrator : Provide filtered and high concentrated oxygen (for medical purpose) to nasal cannula Now I will explain some products that have functions of providing air. First, there is a market for Inogen G3, which is an oxygen concentrator which provide filtered and high concentrated oxygen to nasal cannula. Because it is light, small in size, and enough duration of battery, it is convenient for people to carry it around. We think we can use this product, for medical purpose, to connect it with the nasal cannula.

The related product Portable air pump Name Mini lung pro Dimensions L/W/H : 5.7 / 3.2 / 9.2 (cm) Weight 157.3 g Battery Duration Up to 4 / 8 / 12 hours Price ¥ 190.00 (약 34,000원) : Provide filtered air to the nasal cannula Second, this image is a mini lung pro, which is a portable air pump that provides already-filtered air. The benefit of this product is that it is light, small in size, battery duration, and cheap. Therefore, we believe we can use this product, for general user, to connect the nasal cannula as well.

search report NAME : Nasal Cannula attached Particulate mask Contents of the invention : Nasal Cannula 를 통해 산소 이외의 미세먼지가 유입되는 것을 방지하기 위해 비강 캐뉼라에 미세먼지 마스크가 결합된 형태 또는 미세먼지 마스크가 탈부착 가능하도록 한 형태를 특징으로 함 Key word : Cannula, Mask, Nasal, Filter, Dust, Last week, we searched up for a patent regarding this product, using the keywords: cannula, mask, nasal, filter, and dust.

search report A patented product similar to ours in that the product has a nasal cannula connected with filters But the product is not identical to ours. We can apply a patent on our product. We found a patent. Results show that there is a patented product similar to ours, in that the product has a nasal cannula connected with a filter, but, as you can see in the image, the product is just the combination of a nasal cannula and filters. The product is not identical to ours. So we think we can apply a patent on our product.

Our future plans Purchase various types of masks, analyze them, and choose which one fits best with our product. Investigate the method of attaching the nasal cannula to the mask. This week, we plan on purchasing various types of masks, analyze them, and choose which one fits best with our product. We will also investigate the method of attaching the nasal cannula to the mask.

Q & A That concludes our presentation. Thanks for listening to me. We will now have a Q&A session
