Description

Structure of protective clothing for sound pressure and protection

The present invention relates to protective clothing, and more particularly, negative pressure protective clothing or general protective clothing can be selectively used as a single protective clothing, and negative pressure and protective clothing that can be easily fixed to a seat when a patient with respiratory infectious diseases is moved to a hospital or home country It is about the structure of the protective suit.

In line with the trend of globalization, real-time information can be checked anywhere in the world, and due to the development of transportation, it is possible to visit anywhere in the world in one day. In line with this trend, infectious diseases are also spreading rapidly. It first appeared in Guangdong province in southern China in 2002 and spread worldwide after being infected by a Chinese-American business operator, resulting in more than 8,000 cases in 30 countries and 774 deaths among them. In recent years, since April 2012, Middle East Respiratory Syndrome, also known as “MERS,” which has been infected mainly in the Middle East such as Saudi Arabia, has infected more than 1,300 people in the Middle East alone, resulting in 500 deaths. In addition, at present, a corona virus infection, also known as Corona 19 (COVID-19) has occurred, which has led the World Health Organization "WHO" to declare a 'pandemic' that announces a global pandemic. Due to the infection, it is necessary to keep a certain distance if possible, and many problems arise as the medical staff must perform non-contact treatment even during treatment. In order to solve the above problems, Patent Registration No. 10-1362397 "Bacterial Prevention System of Bio Clean Room" effectively controls the air inside and outside the isolation room to prevent deterioration of the patient's condition, maintain a healthy and comfortable isolation room, and especially A prevention system that can efficiently drive the differential pressure module even with power is provided, and in order to prevent the medical staff from being transmitted to the virus during treatment, Patent Publication No. 10-2016-0004787 "Removable and combined protective clothing for preventing the spread of acute viral infectious diseases" In this case, the detachable top, bottom, and skirt-type cover body are combined with a Velcro structure, and the antibacterial pad is placed between the top, bottom, and skirt-type cover body, so that microorganisms that spread acute viral infectious diseases are introduced into the inside of the uniform. .

According to the present invention, protective clothing must be worn for disease control safety, even in cases with severe symptoms and few symptoms, but the economic burden increases and becomes ineffective, and in most countries, when symptoms are severe, Embrace and patients As the person visits a hospital or quarantine facility directly, there is a risk of secondary infection. In addition, if the nationals are abroad or if it is difficult to travel due to a relatively long distance, it is difficult to travel by plane, vehicle, or ship When moving through the system, it takes a lot of time as a separate patient is moved by wearing a protective clothing or by putting a quarantine curtain on the bed. can't be In addition, in the case of a 'pandemic' that announces a global pandemic, an unspecified number of people can be a suspect, so the control equipment owned by each country is inefficient and physically expensive.
