Description

AIRBORNE PATHOGENS REDUCTION DEVICE

This application relates to an air treatment device that will reduce the spread of airborne health hazardous matter like pathogens, viruses, bacterium and etc. More specifically, the present application is directed to apparatuses and methods designed to reduce airborne pathogens transmission by exhalation or inhalation from one person or living being to another.

Toward the end of year 2019, China was hit with a corona virus outbreak. This virus was later named by the World Health Organization as COVID-19. By December 2020, the COVID-19 infection has spread worldwide to become a pandemic. Globally, about sixty five million victims were infected with about one million five hundred thousand deaths. Many nations implemented partial or full lock down and closed their border to international travel. Many business activities grounded to a near halt. As the number of infection goes down, nations started to re-open their economic activities. As soon as this happen, the infection rate rebound and nations have to implement the lock down again. As a result, many businesses are facing tremendous pressure of closure. Without the presence of an effective vaccine, it would be difficult to restart business activities.

To reduce the rate of infection, most health authorities typically promote hand washing and covering the mouth with mask to restrict the airborne or aerosolized transmission of the COVID-19 virus. With aerosolized transmission, the viruses linger in the air like a fine mist long after an infected person has departed the area. When the virus is spread by aerosolized transmission, it is extremely difficult to prevent transmission to additional persons exposed to infected air.

The use of masks will help to reduce the spread of the viruses, but this is fraught with practical difficulties. Masks are physically uncomfortable, they impair breathing (which is already impaired for many patients), and they disrupt speaking. To be effective at all, it would probably be necessary for the masks to be worn not just by the patients, but also by infected individuals who does not exhibit the common symptoms of the infection. While the use of the mask can reduce the spread of virus, it is still not ideal.

Another approach to reducing the transmission of the pathogens is the use of filtration or sanitization systems. US3757495 ("Portable air purifier", 11 September 1973, ), US5997619 ("Air purification system", 10 July 1998, ) and US6783578 ("Air purification unit", 31 August 2004, ) are some of the prior art systems using this approach. These systems are usually placed within an interior area. Interior air is directed into the system and goes through a filtration or sanitization process (example, HEPA or high efficiency particulate air filter, ultra violet light treatment and etc.) that remove or destroy the airborne pathogen. The main problem is that it required a considerable amount of time before the pathogens are removed from the interior air. If there is any infected but asymptomatic patient within the area, airborne pathogens are quickly transmitted to most people within its vicinity before the filtration system can effectively clean the interior air. Furthermore, there will usually be some blind spot regions of the enclosed environment that the system will fail to sanitize.

As an improvement over the filtration or sanitization systems mentioned above, portable version of these systems was invented. Some examples are US7008469 ("Portable air filtration system utilizing a conductive costing and a filter for use therein", 7 March 2006, ) and WO2018/178231 ("Personalized air cleaning device", 30 March 2017, ). These improved systems can be placed near infected patients and provide an improvement in term of pathogens spread. The problem is that there is still a considerable gap between the infected patient's mouth or nose and the portable sanitization system. There is still a high probability of having a large portion of the airborne pathogens emitting from the patient's mouth or nose being transmitted to individuals nearby.

WO2011/006509 ("Device and method for reducing spread of microorganisms and airborne health hazardous matters and/or for protection from microorganisms and airborne health hazardous materials", 17 July 2009) in shows a filtration or ventilation device for reducing the transmission of the airborne pathogens. The filtration device is mounted on furniture (example, the head region of a bed). Air exhalation from a person is directed into the filtration device and cleansed. Like the previous filtration system mentioned above, there is still a considerable gap between the infected patient's mouth or nose and the filtration device. There is a considerable risk of airborne pathogens transmission.

Another method to reduce pathogens spread is the use of a modified ventilation system. The theory is that dilution of infectious air with clean air will reduce the concentration of pathogens and hence the likelihood of transmission of the disease. US4035018 ("Device for distributing conditioned air", 17 Oct 1975, in ), US6318113 ("Personalized air conditioned system",12 June 2000 in ), US6910961 ("Indoor ventilation system with personalized ventilation device and its method of usage", 17 September 2003 in ), US7892306 ("Multi-use personal ventilation filtration system", 25 September 2008, ) and US9050382 ("Close proximity airborne influenza/pathogen mitigator",6 March 2014, ) are some examples. Clean air from a ventilation system is released around the facial zone of a person. This method of operation reduces the person from airborne pathogens infection. The problem is that it also accelerates the spread the airborne pathogens from an infected person to other uninfected individuals around the enclosed environment who are not cover by the system.

Many medical experts and scientists have expressed their opinion that a pandemic like COVID-19 can only be solved with an effective vaccine. Unfortunately, the applications of an effective vaccination program are filled with many obstacles. First, the development of vaccine is usually a very long process. By cutting short this process, the long term side effects of the vaccination cannot be determined. Second, even if the vaccine is safe, there is not enough data to determine the effective duration of protection. Third, the storage, transportation and distribution of vaccine required enormous resources. Forth, it may be difficult to convince the majority of the general population that the vaccine is safe and effective. For the short to medium term, it may not be wise to rely solely on the development of vaccine.

The wearing of mask, social distancing, frequent hand washing and current air sanitization or filtration systems helps to reduce the spread of the virus, but it is still not enough. It is the objective of this application to provide a method of reducing the spread of pathogens or viruses outbreak while allowing a safe re-opening of business activities.

In accordance with one embodiment, an airborne pathogen reduction device creates a suction force at an air inlet that is placed around the mouth or nose region of a living being or person. Airborne pathogens or droplets exhaled from the person are being sucked into the airborne pathogen reduction device through the air inlet. These pathogens go through a sanitization process before it is released back to the environment.

shows a typical office meeting room 1202 where pathogen transmission can occur between office workers. A first office worker 1208 is talking actively, emitting a mist of airborne exhalation droplets 1214 within the meeting room. A second office worker 1210 is not talking but is also emitting a smaller mist of airborne exhalation droplets 1212 due to breathing. An air conditioner 1206 is pushing out cool air in order to maintain the room temperature at a comfortable level. The effect of the air conditioner 1206 causes air circulation within the meeting room 1202 and accelerates the spread of airborne droplets from different office workers. If any of the officer workers are active carrier of an infectious pathogen, all the office workers within the meeting room 1202 will be infected within a short period of time. An air purifier 1204 helps to remove some of the airborne pathogen within the meeting room 1202. Unfortunately, the effect of the air purifier 1204 is not enough to prevent the spread of an infectious pathogen.

One embodiment of an airborne pathogen reduction device 1302 is shown in . A number of the airborne pathogen reduction device 1302 are placed on a meeting room table 1308 in front of each of the office workers.
