Description

The present invention relates to an exhaled virus inactivating system capable of capturing and inactivating a virus contained in exhaled breath.

In recent years, new respiratory viral infections such as Severe Acute Respiratory Syndrome (SARS) and Coronavirus Infection (COVID-19) have become prevalent. Vaccines or antiviral drugs have been developed to prevent the spread of the infection, but it takes time to spread sufficiently. It is preferable to take prompt measures to reduce the infection so far.

In addition, the virus from an infected person is contained in the exhaled breath and is a source of infection for nosocomial infections and home medical care personnel and medical personnel. At the same time, the infected person's own breathing returns to the infected person's lungs and creates a new infected area in the lungs, causing proliferation and fear of aggravation. Therefore, there is a problem that it is necessary to eliminate the produced virus from the infected person as much as possible.

On the other hand, wearing a face mask to prevent the spread of infection is a generally accepted non-pharmacological method. For example, the breathing apparatus described in Patent Document 1 is characterized in that an LED that irradiates ultraviolet rays is incorporated in the face mask. Therefore, it is explained that the air can be disinfected by irradiating the wearer with ultraviolet rays when inhaling and exhaling.

In general, it is said that ventilation is important in the hospital room of a virus-infected person, but mere ventilation has a low effect of eliminating the exhaled virus and cannot prevent the spread of the COVID-19 virus, so many infected people are affected. It has been produced and has become a social problem.

Therefore, the present invention is intended to prevent the spread of the virus from home-based medical treatment and hospitalized infected persons, which are the main sources of virus infection in the city, and to reduce the infection in the city. That is, the main purpose is to prevent the spread of the virus, and the purpose is to reduce secondary infections.

In order to achieve the above object, the exhaled virus inactivating system of the present invention includes a virus inactivating device including a face mask covering the nose and mouth, a blower, an addition device, an enlargement part, and the face mask. It is provided with a hose that communicates the internal space of the virus with the virus inactivating device, and a virus inactivating treatment unit connected to the virus inactivating device.

As described above, the exhaled virus inactivating system of the present invention includes a face mask, a virus inactivating device, a hose, and a virus inactivating processing unit connected to the virus inactivating device. With such a configuration, it is possible to prevent the spread of the virus from the home caregiver who is the source of the virus infection and the infected person in the hospital, and to suppress the nursing infection and the nosocomial infection.

It is composed of a vessel 4 and a hose 8 which is an inactivating processing unit that forms a space having a length for ensuring virus inactivation.

The face mask 2 has a base portion 21 as an outer frame, a flap portion (cover) 22 that can be opened and closed with respect to the base portion 21, a hooking string portion 23 for attaching to the human H, and a side surface. It is composed of a ventilation hole 24 and. The base portion 21 is a frame body that constitutes the outer shape of the face mask 2, and is formed of, for example, an elliptical or rounded quadrangular frame shape by synthetic resin.

The cover 22 is a main body that covers the front surface of the face mask 2, and when an infected person coughs, it discharges more exhaled breath than normal exhaled breath, but the inside for temporarily capturing and accommodating it and guiding it to a hose. In order to form the space 20, it is formed in a trumpet shape by synthetic resin, and has ventilation holes 24 for passing air intake near the edges of the left and right base portions 21. It is also possible to use a spacer (not shown) instead of the ventilation hole 24 to slightly lift the cover 22 from the face and ventilate through the created gap.

The virus inactivating device 4 is composed of a blower 5, a surfactant mist addition device 6, and an expansion unit 7. As shown in FIGS. 2A and 2B, the virus inactivating device 4 is composed of an upper half portion 4A and a lower half portion 4B in a half-split type in order to facilitate processing and maintenance, and is coupled. It is configured to be openable and closable by being connected with. The virus inactivating device 4, the hose 3, and the virus inactivating processing unit (hose) 8 are connected via a joint. Therefore, the exhaled virus inactivating system 1 is made easy to handle by connecting the mask hose 3, the virus inactivating device 4, and the virus inactivating processing unit 8 with a joint.

The hose 3 is formed of a synthetic resin or synthetic rubber in a long cylindrical shape, and has an internal space 20 partitioned by a base portion 21 of the face mask 2 and a trumpet-shaped cover 22, a virus inactivating device 4, and the hose 3.

In addition, in the case of group correspondence described later with reference to FIG. 3, a check valve 6B with a pressure adjusting function may be connected in the middle of the hose 3.

The virus inactivating device 4 is connected to the end of the hose 3 and is a device that inactivates the exhaled virus by, for example, plasma ions, ultraviolet rays, titanium oxide, chlorine dioxide, or the like. That is, the virus inactivating device 4 is a device for completely inactivating a virus by physical means or a chemical agent. Here, as a means for the envelope to inactivate the lipid virus, a release pathway having a space for inactivating with a detergent solution mist is used.

The blower 5 generates a negative pressure so that the exhaled air containing the virus is introduced into the virus inactivating device 4, and is arranged at the upstream end of the virus inactivating device 4. The blower 5 can adjust the negative pressure so that the exhaled air can be sucked without leakage. That is, the generated pressure of the blower 5 is adapted to generate a negative pressure adjusted so as to be sucked according to the amount of exhaled breath (vital capacity) discharged by the infected person using this system, and the controller C generates the pressure. Be controlled.

(Action)
Next, the operation of the exhaled virus inactivating system 1 of this embodiment will be described with reference to FIGS. 1 and 2. In the state shown in FIG. 1, the exhaled air containing the virus is sucked from the infected person through the mask by the blower 5, introduced into the virus inactivating device 4 through the hose 3, and the exhaled air is exhaled by the virus inactivating device 4 mist shower. Is added, the virus is inactivated by the hose 8 which is the inactivating treatment part by the pressure of the blower 5, and the treated gas is released to the atmosphere from the end of the hose 8.

Further, in the exhaled virus inactivating system 1, the entire device can be integrated on one wagon 9 in order to facilitate the transportation and installation of the system itself. As shown in FIG. 4, the wagon 9 is a trolley provided with lower casters 91 and 91, and can mount and store the entire virus inactivating system 1 described above. In FIG. 4, the hose 8 as the virus inactivating treatment unit is in a folded state.

(effect)
Next, the effects of the exhaled virus inactivating system 1 of this embodiment will be listed and described.

(1) As described above, the exhaled virus inactivating system 1 includes a face mask 2, a virus inactivating device 4, a hose 3, a virus inactivating processing unit 8 connected to the virus inactivating device 4, and the virus inactivating unit 8. It has. With such a configuration, it is possible to prevent the spread of the virus from inpatients who are the source of virus infection, prevent nosocomial infections and infections of medical personnel, and reduce infections in the city.

That is, the exhaled breath containing the virus collected by the face mask 2 is introduced into the virus inactivating device 4 through the hose 3 by the negative pressure of the blower 5. Then, the exhaled breath inactivated and purified by the virus inactivating device 4 and the hose 8 is released to the external space 90. Therefore, not only the surrounding humans but also the patient himself does not inhale the air containing the virus again.

(2) Further, the face mask 2 aggregates and sucks the exhaled air of the infected person, but since the range of the exhaled air cannot be specified, the exhaled air and the surrounding air are also sucked together by the negative pressure. On the other hand, when the patient inhales air, the air is inhaled from the suction hole provided in the base portion of the face mask, and the exhaled air once discharged is not inhaled at all.

(3) Further, since the virus inactivating device 4 can be dissolved with a surfactant or a detergent solution when the virus envelope is lipid, the exhaled virus can be added by adding the surfactant solution (or detergent solution) as a mist. Can be completely inactivated.

(4) Then, it is preferable to provide a controller C in which the blower 5 can change the output according to the amount of exhaled air sucked and controls the output of the surfactant solution mist shower to be added.

(5) Further, a plurality of face masks 2, ..., a plurality of hoses 3, ..., And a plurality of hoses 3, ... Attached to the plurality of human beings H shown in FIG. By providing a virus inactivating device 4 and a blower 5 that are commonly connected to at least a part of the above, a virus contained in the exhaled breath of a group consisting of a plurality of human H, ... You will be able to collect and inactivate (described later).

Further, the exhaled virus inactivating system 1 has the following effects.

That is, the present invention prevents the exhaled virus, which is once excreted from the alveolar of a virus-infected person, to be taken into the inspiration and returned to the virus to form a new infected area in the lung, and is a medication containing a vaccine. It may be possible to assist the treatment with such means to lead to healing, or to facilitate the healing of the infected site with the immunity that the infected person originally possesses without being disturbed by the return virus.

Further, as shown in FIG. 3, the exhaled virus inactivating system 1 of the present invention can be designed according to the scale of the ward, and can be treated alone or connected to a plurality of infected persons at the same time. is there. In a ward that accommodates a large number of infected people, a centralized virus inactivating device that collectively inactivates the exhaled viruses of multiple infected people can be constructed, and a suction tube connected to the centralized suction virus inactivating device is provided. We will build a system that connects people through joints provided in branch suction pipes.

Specifically, as shown in FIG. 3, the exhaled virus inactivating system 1 has a plurality of face masks 2, ... And a plurality of hoses 3 connected to a plurality of humans H, .... In addition to being provided with, a virus inactivating device 4 and a blower 5 are provided as common equipment that is commonly connected to at least a part of a plurality of hoses 3. Therefore, the virus can be inactivated with efficient equipment. In this case, in order to prevent the spread of infection, it is preferable that each human H is provided with a check valve 6B with a pressure adjusting function that provides a necessary negative pressure for opening and closing the flap portion (cover) 22 of the mask. That is, it is preferable that the check valve with a pressure adjusting function is arranged not in the central trunk pipe 3A but in the individual hoses 3 connected to each person H.

In addition, the exhaled virus inactivating system 1 has the following effects.

1) Dosing support The system of the present invention can be used alone to prevent the attack of the exhaled virus, but its effect can be enhanced when used in combination with the current treatment with medication. That is, there is a possibility that the treatment period can be shortened.

2) Reduction of aggravation By following the aggravation-suppressing effect of forced ventilation in Vietnam, there is a possibility that the effect of preventing medical collapse can be obtained by suppressing the aggravation of primary and secondary infected persons.

3) Since this system does not invade the body of infected people, side effects, allergies and pollution caused by applying this system do not occur. Furthermore, since this method captures and inactivates the entire virus, it is not affected by mutations, and it is expected to develop a method for use in combination with the vaccine currently being developed.

4) The system of the present invention may be applicable not only to COVID-19 but also to the treatment of colds, MERS and SARS, which are coronavirus infections, and influenza.

(Reason for reaching the present invention and future development)

1) Since ancient times, the symptomatic treatment for colds in Japan has been to close the room to prevent cold winds, boil water with a kettle, and humidify the air in the room.
Initially, COVID-19 is a coronavirus and is the same species as the coronavirus, which is the causative agent of the common cold, so it was thought that humidification, which is a symptomatic treatment for the common cold, is the remedy.
A COVID-19 infection occurred on the cruise ship Diamond Princess, which was anchored at Yokohama Port in March 2020, and passengers and crew members were quarantined and stayed among the passengers who left the ship with a negative PCR test after that period. It is said that there was a person who escaped the infection by hanging the medium laundry in the room and drying it and humidifying the air in the room. This method is considered to be one of the applicable coronavirus countermeasures if there is no other method.

2) Vietnam's achievements When SARS (Severe Acute Respiratory Syndrome) became epidemic in 2002/3, a Vietnamese hospital succeeded in recovering a patient by expelling the air in the hospital room from the back to the window with a powerful fan and ventilating. Therefore, there is a report that strong ventilation is very important (Dr. Kuniaki Neji, Director of the Institute of Biological Resources). As of February 9, 2021, in Vietnam with a population of 96 million, the current COVID-19 infectious disease was 2001 with 2001 infections and 35 dead, which are 4/1000 and 1/1000 of Japan, respectively. 7.
The death toll of 35 means that no one is aggravated, that is, healed before it becomes aggravated, because there is no reinfection with the return virus and the aggravation can be prevented. I have to think about it. Therefore, the method of the present invention could be found.
Here, the importance of ventilation is considered, and it is not just ventilation, but strong ventilation that blows the exhaled virus from the mouth is required. Based on this result, the present invention was devised for the purpose of eliminating the exhaled virus. In Japan, it is rare that the treated gas can be released into a wide free space, so we had to take a method of collecting and inactivating exhaled breath.

3) Future developments Japan is showing a pandemic appearance despite the efforts of medical personnel and the implementation of various measures, and COVID-19 is rampant in Europe, the United States, South America and Africa, including the United States. There are many places where the swords are shaken. It would be greatly appreciated if the system of the present invention could reduce the number of victims as much as possible.

Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and design changes to the extent that the gist of the present invention is not deviated are included in the present invention. included.
