Description

Infectious disease protection system and antibacterial agent

The present invention relates to an antibacterial agent mainly composed of amino acids extracted from cereals, and an infectious disease prevention system sprayed with the antibacterial agent.

In recent years, we hear news such as norovirus outbreaks and spreads every year.
In fact, the infectivity of norovirus is very strong, and even a very small number of individuals (10 to 100) can infect humans.
Norovirus is said to be resistant to dryness and airborne infection (spray nucleus infection), and it is decisively different from food poisoning symptoms caused by other pathogens in that the virus spreads from person to person and is secondarily infected. For this reason, it is difficult to prevent the spread of infection by norovirus in the same way as general food poisoning countermeasures.

At present, there is no such effective vaccine against norovirus, and there is a troublesome property that even a person who has been infected once is repeatedly infected.
Norovirus also has considerable heat resistance, and is not inactivated at 60 ° C, but is finally inactivated by heating at a high temperature of 85 ° C or higher for 1 minute.
Norovirus is also highly resistant to disinfectants and will not be inactivated unless it is a high concentration (500 to 1,000 ppm) chlorinated solvent.

A further characteristic of the virus is that it does not grow in foods but “grows only in the human intestinal tract”.
After the infected person recovers from the disease (norovirus infection), norovirus is discharged in the feces for more than 2 weeks.
In addition, the virus is also discharged together with stool for those who have an innocuous infection with norovirus (infected individuals who are infected with norovirus but have no obvious manifestation of infection).

Since norovirus is discharged together with the excrement of the infected person in this way, the “infectious route when using the toilet”, which is a shared space, is considered as a problem.
As one of the grounds for suggesting such an infection route of Norovirus, it was verified by using a pseudo-defecation that mimics watery diarrheal stool. There is an experimental result (Nagano Hokushin Insurance Welfare Office).

According to the results of this experiment, it has been confirmed that a large amount of pseudo defecation scattered matter also adheres to the Japanese style toilet JT and its surroundings (peripheral floor and rear wall surface) (see FIG. 12).
For this reason, there is a possibility that the scattered matter (virus contamination VP) adheres not only to the human body / clothes of the person who defecates, but also to the human body / clothes of the toilet user after that.

In addition, according to the result of the experiment, “how much viral contaminants adhere to the human body / clothes (lower body) during defecation” has also been confirmed (see FIG. 13).
As can be seen from FIG. 13, in the Japanese style toilet, excrement (virus contamination VP of the infected person) is scattered on the footwear FW such as shoes and the trousers PT (hems and buttocks) to be virus-contaminated. Probability is high.
In both Japanese-style and Western-style toilets, scattering of excrement on the buttocks and thighs can lead to virus contamination in the underwear and pants, and there is a risk that the virus will spread by changing clothes.

Furthermore, in the above experiment, it was also confirmed that “how much viral contaminants adhere to the cuffs of hands and outerwear when excrement is treated (wiping the bottom)” (see FIG. 14).
The experimental results shown in FIG. 14 indicate that the virus contaminant VP adheres not only to the waste paper directly wiping away like the toilet paper TP, but also to the palm PM holding the paper TP and the cuffs of the clothes CL. It became a suggestion.
In addition, there are many common items that all users use, such as flush levers and doorknobs for running water in the toilets, which helps spread viral contaminants.

In particular, if a person who handles food (for example, an employee who cooks in a kitchen like a school lunch center) contains a person who does not seem to be indistinguishable from an uninfected person, the person in charge of the other kitchen The risk of being contaminated with virus in food and tableware is increased due to the virus contamination VP adhering to the employee without knowing it, and the infection easily spreads on the scale of hundreds.
If it is a norovirus adhering to food, it can be said that the defense can be easily done by heating for 1 minute at a temperature of 85 ° C. or higher. Rather, it seems that it is more difficult to prevent infections caused by contaminants on the body and clothes of the person who handles foods because they cannot be protected by simple measures such as hand washing.

In order to stop the spread of this kind of infectious disease, various technical developments for disinfecting the human body have been attempted (see, for example, Patent Document 1).
Furthermore, although it is not a technique for direct disinfection of the human body, a disinfecting and deodorizing device (Patent Document 2) that sprays an atomized disinfectant solution into a person's living space, disinfecting footwear that is an article frequently used by people A disinfection device has been devised for the purpose of preventing the spread of infectious diseases when applied (see Patent Document 3).

Japanese Patent Laid-Open No. 2015-100454 JP 2011-0667614 A JP 2005-095528 A

According to the disinfecting apparatus of Patent Document 1, when the foot pedal is depressed, the disinfecting liquid is ejected from the disinfecting liquid bottle placed on the table. Therefore, the user can spray the disinfectant without touching the top of the disinfectant bottle.
However, with the technique of the literature 1, disinfection effect is hardly obtained for viruses attached to the lower body and the vicinity of the feet.

The spraying device of Patent Document 2 is designed to atomize the sterilizing and deodorizing liquid and spray it in the air so that it can effectively eliminate sterilization and deodorization of the living space and suppress the occurrence of defects such as metal corrosion. Has been made.
However, in general, the ventilation fan is often operated for the purpose of deodorization in the toilet. Therefore, when the spraying device of the literature 2 is used in the toilet, the mist-like disinfectant sprayed in the toilet space is discharged (ventilated) from the room, and the sterilization and deodorizing effect may be diminished. is assumed.

Further, the technique disclosed in Patent Document 3 is a technique that focuses on “disinfecting footwear” as disclosed in Reference 3 and FIG.
Therefore, even if this device configuration is directly applied to norovirus infection countermeasures (human body disinfection), the feet (foot and trouser hems) are firmly disinfected, but the hands and outer cuffs are not disinfected. It is difficult to obtain an appropriate infection prevention effect when the user leaves the toilet.
Furthermore, since the article 3 assumes articles (footwear) that do not move around spontaneously as disinfection targets, the photoelectric switch is automatically turned on when the user enters the room, and the footwear is disinfected. Employees are sterilized by manually turning on the switch.
However, when the human body is sterilized by such switch control, even if the photoelectric switch is turned on when the user enters the toilet, the entrance portion can be quickly passed or the sterilizing effect can be sufficiently exerted. A case where the user does not conveniently stand at a suitable spray position can actually occur sufficiently.

The present invention has been made in view of the above-mentioned problems, and “when a user of a facility / equipment (especially a toilet) shared by a large number of people leaves the facility” is caused by a norovirus or the like. The purpose is to prevent.

[First invention]
Therefore, in order to solve the above problems, the infection prevention system according to the first invention of the present application is:
Two or more columnar sprayers are placed upright at both ends of the straight line or at each vertex of the polygonal region, and the surface with the injection holes of the columnar sprayer is set at the midpoint of the straight line or the center of gravity of the polygonal region An infectious disease prevention system that disinfects the human body by spraying antibacterial agents containing amino acids extracted from cereals simultaneously from the spray holes of each columnar sprayer,

A liquid tank for storing the antibacterial agent;
A rod-shaped hollow straw that holds the discharge port outside the liquid tank and is inserted into the liquid tank so that the suction port is immersed in the antibacterial agent;
A compressor that compresses air taken from outside and injects it from an air nozzle;
A mist generation chamber in which a closed space into which the air nozzle and the discharge port of the liquid straw are inserted, and a floating droplet nozzle that discharges the antibacterial agent suspended in a mist form in the closed space, is attached;
Two or more columnar sprayers configured to house the guide pipe with the injection hole therein;
A guide tube connecting the floating droplet nozzle of the fog generating chamber and a guide pipe inside the columnar sprayer;
A switch for controlling power supply to the compressor, and is a foot switch that is turned on when a load is applied by a user's stepping operation and turned off when released from the load;
With

When a foot switch placed on a straight line sandwiched between the columnar sprayers or in a polygonal region surrounded by the columnar sprayers is turned on by the user's stepping operation and power is supplied to the compressor,
The antibacterial agent is sucked up from the liquid straw into the mist generation chamber by the negative pressure generated in the mist generation chamber by the air being jetted from the air nozzle, and the mist-like antibacterial agent is discharged from the floating droplet nozzle. ,
The antibacterial agent discharged from the floating droplet nozzle is sprayed from the injection hole of the columnar sprayer to the user who operates the foot switch via a guide tube and a guide pipe.

As described above, it is difficult to block the virus from being taken from the toilet even if the existing techniques such as Patent Documents 1 to 3 are applied.
However, according to the present invention, norovirus contaminants attached to the human body and clothes during use of the toilet can be accurately identified simply by “stepping on the foot switch 7” without touching a container or the like containing an antibacterial agent. Can be disinfected (Fig. 4).

Further, according to the first invention, the antibacterial agent injection direction (direction of the surface having the injection holes 62) of each columnar sprayer 6 is all directed to the midpoint M of the straight line and the center of gravity G of the polygonal region, and the foot type The switch 7 is installed near the center of gravity G (see FIGS. 8A, 8B, and 8C).
By doing so, the user is inevitably positioned near the midpoint M and the center of gravity G when the foot switch 7 is depressed, so that the antibacterial agent PR is used by all the sprayers 6 to the user. The sterilization effect on virus contaminants that are sprayed intensively on the user and attached to the user is improved.

[Second invention]
Moreover, in order to solve said subject, the infectious disease prevention system which concerns on 2nd invention of this application is
Two or more columnar sprayers are placed upright at both ends of the straight line or at each vertex of the polygonal region, and the surface with the injection holes of the columnar sprayer is set at the midpoint of the straight line or the center of gravity of the polygonal region An infectious disease prevention system that disinfects the human body by spraying antibacterial agents containing amino acids extracted from cereals simultaneously from the spray holes of each columnar sprayer,

A liquid tank for storing the antibacterial agent;
A rod-shaped hollow straw that holds the discharge port outside the liquid tank and is inserted into the liquid tank so that the suction port is immersed in the antibacterial agent;
A compressor that compresses air taken from outside and injects it from an air nozzle;
A mist generation chamber in which a closed space into which the air nozzle and the discharge port of the liquid straw are inserted, and a floating droplet nozzle that discharges the antibacterial agent suspended in a mist form in the closed space, is attached;
Two or more columnar sprayers configured to house the guide pipe with the injection hole therein;
A guide tube connecting the floating droplet nozzle of the fog generating chamber and a guide pipe inside the columnar sprayer;
A contactless IC (Integrated Circuit) card possessed by the user of the infectious disease prevention system;
An apparatus that controls power supply to the compressor, and an IC card reader that turns on the compressor when a non-contact IC card held by a user is detected;
With

When the IC card reader placed on a straight line sandwiched between the columnar sprayers or in a polygonal region surrounded by the columnar sprayers detects a non-contact IC card held by the user, the compressor is turned on. When power is supplied to the compressor,
The antibacterial agent is sucked up from the liquid straw into the mist generation chamber by the negative pressure generated in the mist generation chamber by the air being jetted from the air nozzle, and the mist-like antibacterial agent is discharged from the floating droplet nozzle. ,
The antibacterial agent discharged from the floating droplet nozzle is sprayed from the injection hole of the columnar sprayer to the user who operates the foot switch via a guide tube and a guide pipe.

According to the infectious disease prevention system according to the second invention, although the system configuration is different from the first invention in that the IC card reader 71 is adopted as a switch (see FIG. 11), the function for spraying the antibacterial agent is the first. By having the same technical features as the invention, it is possible to achieve the “disinfection effect equivalent to that of the first invention against virus contaminants”.

[Third invention]
Moreover, in order to solve said subject, the infectious disease protection system which concerns on 3rd invention of this application is an infectious disease protection system which concerns on 1st or 2nd invention,
The columnar sprayer was configured to have a height of 1 m or more when placed upright.

According to the third aspect of the invention, by selecting a suitable height of the sprayer, it is possible to sterilize without leaking below the user's arm and lower body when returning from the toilet.
The columnar sprayer can be designed to an arbitrary height as long as it is 1 m or more. However, in order to eliminate the discomfort caused by the antibacterial agent PR applied to the face portion or the like, it should be placed below the shoulder or chest. It is desirable to select a numerical value (height) within a range that can be sprayed.

[Fourth Invention]
In order to solve the above problems, the antibacterial agent according to the fourth invention of the present application is:
An antibacterial agent comprising amino acids extracted from cereals,

An amino acid mixed solution extracted by separating a solid from a grain solution to which a flocculant has been added after heat treatment and filtration treatment, and an amino acid mixed solution containing a soybean extracted amino acid;
Purified water and special reducing alkaline ionized water having a pH value of 12,
Butylene glycol,
A cationic surfactant,
A zwitterionic surfactant,
A nonionic surfactant,
Chelating agents,
It was set as the structure containing.

According to the antibacterial agent according to the fourth invention, since the virus inactivating effect and the antibacterial effect are significantly recognized (see Table 1 and FIG. 5), the infectious disease caused by the toilet user's excrement (viral contamination) It becomes possible to prevent expansion.

In addition, the basic manufacturing method of the antibacterial agent PR (FIG. 1) used in the infection prevention system of the present application is as follows.
First, beans (for example, soybeans) are immersed in water, and then beans that have sufficiently absorbed moisture are crushed into a bowl shape. Subsequently, the bean-like bean solution is heated at around 100 ° C. for 10 to 20 minutes, and further at around 80 ° C. for 20 to 60 minutes.
Thereafter, this solution is filtered, and water (purified water and special reducing alkali ion water) and a flocculant are added to the liquid obtained by filtration. Then, the antibacterial agent PR can be obtained by heating the solution after the addition at around 100 ° C. for 20 to 60 minutes to separate the solid matter.
The final pH value of the antibacterial agent is around pH 6.0 to pH 7.5.

Antibacterial agent PR produced according to the above manufacturing method is soybean extracted amino acid / amino acid mixed solution / surfactant (cationic surfactant, zwitterionic surfactant, nonionic surfactant), chelating agent, special reducing property It contains alkaline ionized water (pH 12) / butylene glycol (or alcohol).
Among these, the compositions characterizing the antibacterial agent PR of the present invention are “butylene glycol” and “special reducing alkaline ionized water”.

Butylene glycol originally has a high bactericidal effect, and furthermore, butylene glycol is not toxic to human skin. Therefore, when implementing disinfection (inactivation of viruses, antibacterial / sterilization against bacteria) using the antibacterial agent PR of the present application. “Ensuring user safety” can also be ensured.

Further, in the present invention, about 6% of a colorless transparent and odorless liquid “special reducing alkali ion water” is added to the total amount of the antibacterial agent PR. The alkaline ionized water is not pure water but contains minerals such as sodium and magnesium.
This special reducing alkaline ionized water has a pH (power of hydrogen) value of pH (20 ° C.) of 12 to 12.4, indicating “very strong alkalinity”, and the specific gravity (20 ° C.) is 1.002.

It has been experimentally confirmed that such strong alkaline special reducing alkaline ionized water can inactivate Norovirus and influenza virus.
If special reducing alkaline ionized water with such effects is applied to disinfection after toilet use, it is possible to "inactivate various viruses hidden in virus contaminants attached to the body and clothes of toilet users and control bacteria" It is.

The surfactant used in the antibacterial agent PR may be a general surfactant as long as it has an antibacterial action.
As an example, cationic surfactants include benzalkonium chloride that exhibits bactericidal properties by denaturing bacterial cell membrane proteins.
Examples of zwitterionic surfactants having antibacterial activity include laurylaminopropionic acid, and examples of nonionic surfactants having antibacterial activity include polyoxy-propylene glycol.
Due to the high penetrability of the surfactant, the antibacterial agent PR can efficiently penetrate into virus contaminants attached to the human body and clothes.
Furthermore, as for the chelating agent added to the antibacterial agent PR (which forms a metal ion and a complex ion by coordination bond), a general one such as ethylenediaminetetraacetic acid disodium (EDTA2Na) may be used.
The addition of disodium ethylenediaminetetraacetate (EDTA2Na) prevents precipitation of benzalkonium chloride, amino acids and the like, and also prevents their oxidation.

In addition, if spray disinfection is performed on the human body using a chlorine-based disinfectant, cloth products such as clothing worn by the user may be whitened not only due to the bactericidal and antibacterial effects but also the bleaching effect of chlorine. is there.
However, the antibacterial agent used in the infectious disease prevention system of the present application has been confirmed to be free from decolorization / discoloration as a result of spraying on a dyed textile product and performing a decoloration / discoloration test.
Therefore, even if the antibacterial agent adheres to clothes of the user of the system, it can prevent decolorization (outlined).

Hereinafter, the infection prevention system of the present invention will be described with reference to FIGS.
[Embodiment]
Embodiment of this invention is the example which comprised the infectious disease prevention system 1 (refer FIG. 1) which prevents the infectious disease spread of norovirus by spraying an antibacterial agent to a user when leaving a toilet.

The infectious disease prevention system 1 of the present application includes two or more columnar sprayers 6 at “both ends of a straight line” (FIG. 1) or “each vertex of a polygonal area” (see FIGS. 7A and 7B). Place it upright.
Further, in the system 1, the surface of the column sprayer 6 with the injection holes 62 is positioned at the midpoint M of the straight line L (FIG. 8A) or the center of gravity G of the polygonal region (FIGS. 8B and 8C). )) And disinfect the human body by simultaneously spraying the antibacterial agent PR containing amino acids extracted from the grains from the injection holes 62 of each columnar sprayer 6 (FIG. 1).

This infection prevention system 1
A liquid tank 3 for storing the antibacterial agent PR;
It is a rod-shaped hollow straw, and its discharge port 311 (FIG. 2) is held outside the liquid tank 3 and the suction port 312 (FIG. 2) is inserted into the liquid tank 3 so as to be immersed in the antibacterial agent PR. A liquid straw 31;
A compressor 2 that compresses air taken from outside and injects it from an air nozzle 28;
The mist generation chamber 4 is formed in a closed space into which the air nozzle 28 and the discharge port 311 of the liquid straw 31 are inserted, and the floating droplet nozzle 41 for discharging the antibacterial agent PR suspended in the mist state is attached to the space. And comprising.

Furthermore, the system 1 (FIG. 2)
Two or more columnar sprayers 6 each including a guide pipe 61 having an injection hole 62 therein;
A guide tube 5 connecting the floating droplet nozzle 41 of the mist generation chamber 4 and the guide pipe 61 (FIG. 2) inside the sprayer 6;
The switch controls power supply to the compressor 2 and includes a foot switch 7 that is turned on when a load is applied by a user's stepping operation and turned off when the load is released.

A foot switch 7 placed on the straight line L (FIG. 1) sandwiched between the columnar sprayers 6 or in a polygonal region (FIGS. 7A and 7B) surrounded by the columnar sprayers 6 is provided. When power is supplied to the compressor 2 when turned on by the user's stepping operation,
The antibacterial agent PR is sucked up from the liquid straw 31 into the mist generation chamber 4 by the negative pressure generated in the mist generation chamber 4 by the air being jetted from the air nozzle 28 (FIG. 2), and the mist-like antibacterial agent PR is discharged from the floating droplet nozzle 41,
The antibacterial agent PR discharged from the floating droplet nozzle 41 is sprayed to the user who operates the foot switch 7 from the injection hole 62 of the columnar sprayer 6 through the guide tube 5 and the guide pipe 61. The
Hereinafter, this content will be described in detail.

As shown in FIG. 1, the infection prevention system 1 of this example includes a compressor 2, a liquid tank 3, a mist generation chamber 4, a guide tube 5, a column sprayer 6, and a foot switch 7. The
Further, in the present system 1, an antibacterial agent PR having an antibacterial action is used for disinfecting virus contaminants attached to a human body or clothes.

The antibacterial agent PR has an inhibitory effect on bacteria (antibacterial effect / bactericidal effect) and an inactivating effect on viruses, and is a liquid antibacterial agent containing amino acids sprayed on the human body.
The antibacterial agent PR contains as a main component a natural active ingredient derived from “soybean amino acid” which is a kind of vegetable amino acid.
A detailed description of the experimental results showing the effect of the antibacterial agent PR will be given later.

The liquid tank 3 shown in FIG. 1 is a container that stores the antibacterial agent PR described above.
The liquid straw 31 (FIG. 2) is a rod-shaped hollow straw that is inserted into the tank 3 so that the discharge port 311 is held outside the liquid tank 3 and the suction port 312 is immersed in the antibacterial agent PR.

The compressor 2 shown in FIG. 1 can use any compressor such as a reciprocating type (reciprocating type) or a swash plate type.
The compressor 2 in this example is a reciprocating type in which the piston 23 reciprocates in the cylinder 22 (see FIG. 3), and compresses by changing the volume of the cylinder 22 due to the reciprocating motion of the piston 23.
As shown in FIG. 3, the cylinder 22 of the compressor 2 is provided with a suction valve 25 that opens only inward and a discharge valve 26 that opens only outward.

When the piston 23 moves in a direction to increase the volume inside the cylinder 22, the suction valve 25 is opened and air is taken into the cylinder 22 from the outside.
After the air has been taken in, the air is compressed when the piston 23 moves in a direction to reduce the volume in the cylinder 22, and the compressed air is discharged to the outside of the cylinder 22 by opening the discharge valve 26.
In this example, since the discharge valve 26 is connected to the air nozzle 28 via the air tube 27, compressed air is injected from the nozzle 28. Thereby, the air compressed by the compressor 2 is sent into the mist generation chamber 4 in which the air nozzle 28 is inserted.

The mist generation chamber 4 has a hollow structure having a closed space inside, and the discharge port 311 and the air nozzle 28 of the liquid straw 31 are inserted (FIG. 2).
Furthermore, a floating droplet nozzle 41 that discharges the antibacterial agent PR suspended in a mist form in the same closed space is attached to the mist generation chamber 4.
The floating droplet nozzle 41 serves to discharge the mist-like antibacterial agent PR floating inside the mist generation chamber 4 (closed space).

The antibacterial agent PR sucked up by the liquid straw 31 is diffused in the mist generation state 4 from the discharge port 311 into the mist generation chamber 4.
Further, since the compressed air blown from the air nozzle 28 is discharged from the floating droplet nozzle 41 in the mist generation chamber 4, the mist-like antibacterial agent PR is also transferred from the floating droplet nozzle 41 to the outside of the mist generation chamber 4. To discharge.

As shown in FIG. 2, the guide tube 5 connects the floating droplet nozzle 41 attached to the mist generation chamber 4 and the guide pipe 61 stored in the columnar sprayer 6, so that the floating droplet nozzle is connected. 41 and the guide pipe 61 are made to communicate.

The columnar sprayer 6 is an apparatus configured to store the guide pipe 61 having the injection hole 62 therein (FIG. 2).
Since the size of the norovirus is 27 nm to 37 nm, the nozzle diameter of the injection hole 62 is set to “30 μm” so that the particle diameter of the sprayed antibacterial agent PR is about 20 μm to 30 μm.
In this example, the spray time of the antibacterial agent PR is “2 seconds”, and the spray amount of the antibacterial agent PR per one time is “20 ml to 40 ml”.

Further, in the infectious disease prevention system 1, “two or more” columnar sprayers 6 are installed. These columnar sprayers 6 are installed and used in an upright state.
Furthermore, the present system 1 is “devised in the arrangement pattern of the plurality of columnar sprayers 6” so that virus contaminants attached to the human body and clothes of the toilet user can be disinfected accurately and efficiently. .
One columnar sprayer 6 is installed at both ends of the straight line L or at each vertex of the polygonal region (FIGS. 8A, 8B, and 8C). Further, the antibacterial agent injection direction (direction of the surface having the injection holes 62) of the columnar sprayer 6 is all “directed toward the midpoint M of the straight line L and the center of gravity G of the polygonal region”.

The foot-operated switch 7 is a momentary switch (a system that is turned on only while the button is pressed and a load is applied, and automatically returns to the off state when the button is released from the load).
In this example, when the foot switch 7 is turned on by the user's stepping operation (FIG. 4), electric power is supplied to the compressor 2.
The switch 7 is preferably installed near the midpoint M of the straight line L and the center of gravity G of the polygonal region so that the antibacterial agent PR is efficiently sprayed to the user of the system 1.
In this example, a circular foot switch 7 is used. However, the shape of the switch 7 is arbitrary and may be a “rectangular (for example, rectangular) flat plate switch”.

Next, the “effect of the antibacterial agent PR” used in the present invention will be described based on experimental results.
The antibacterial agent PR of this example uses soybean extract components as antibacterial components.
Soybean contains tryptophan, lysine, methionine, phenylalanine, threonine, valine, leucine, isoleucine, and histidine, which are essential amino acids that cannot be synthesized in the human body among the amino acids necessary for the human body.
Furthermore, soybean contains glycine, alanine, cystine, serine, asparagine, aspartic acid, glutamine, glutamic acid, arginine, tyrosine, and proline, which are classified as non-essential amino acids among amino acids necessary for the human body.

The TCID ₅₀ (TCID: median Tissue Culture Infectious Dose) in Table 1 above is a unit for measuring the virus infectivity titer, and is 50 when the virus dilution is inoculated into a test tube or the like to which cells have been cultured and attached in advance. % Concentration that infects cells.
The unit of the amount of bacteria in Table 1 is “CFU (Colony Forming Unit) / ml”, which represents the number of units capable of forming colonies (the number of bacteria present in 1 ml).

As can be seen from Table 1, this antibacterial agent PR has a significant “inactivation effect on various viruses” including feline calicivirus (substitute for norovirus with similar properties), SARS coronavirus, and influenza virus. .
Norovirus is a virus that causes non-bacterial acute gastroenteritis.
SARS (Severe Acute Respiratory Syndrome) coronavirus is a virus that is a pathogen of severe acute respiratory syndrome.
The influenza virus was tested using the H1N1 strain.

As can be seen from Table 1, antibacterial PR has various antibacterial effects on bacteria including S. cerevisiae, Staphylococcus aureus, enterohemorrhagic Escherichia coli O-157, Escherichia coli, Legionella and Salmonella. It was.
Furthermore, as can be seen from Table 1, the antibacterial agent PR of this example has been confirmed to have an “antifungal effect” that suppresses the growth of mold.

Cereus spores are bacteria that cause food poisoning and are resident bacteria in the intestinal tract.
Staphylococcus aureus is a bacterium that is resident in human skin, digestive tract (intestine), etc. and may cause epidermis infection, food poisoning, pneumonia, meningitis, sepsis, and the like.
Enterohemorrhagic Escherichia coli O-157 is a bacterium that causes hemorrhagic colitis that is often infected from foods that are not sufficiently heated.
E. coli can also be a causative agent of urinary tract infections.
Legionella is a facultative intracellular parasitic bacterium that contains many species that cause Legionella disease, including Legionella pneumonia (Military illness).
Salmonella is an enteric bacterium that includes typhoid, paratyphoid, or infectious food poisoning.

Since various viruses and bacteria including norovirus are lurking in the excrement of persons infected with norovirus, it is desirable to take measures to prevent infectious diseases for toilet users.
As described above, the antibacterial agent PR used in the infectious disease prevention system of this example has a significant virus inactivating effect and antibacterial effect, so that “infectious disease caused by toilet user excretion (viral contamination)” Contributing to the prevention of the spread of

Furthermore, the above components have not only a virus inactivating action and an antibacterial action but also a “deodorizing action”.
Rotting means that organic matter derived from living organisms (particularly, organic matter containing nitrogen such as protein) is decomposed by microorganisms such as bacteria.
Needless to say, the excreta gives off unpleasant odors (mainly odors from “ammonia” and “hydrogen sulfide”) due to the formation and decomposition of spoiled amines (indoles, ketones, etc.).
However, the antibacterial agent PR exhibits an excellent deodorizing effect on “ammonia” as shown in FIG. 5A and also on “hydrogen sulfide” as shown in FIG. 5B. This has been confirmed by experiments.

In addition, the antibacterial agent PR is also effective against “isovaleric acid” (FIG. 5 (c)) and “normal butyric acid” (FIG. 5 (d)), which are representative components of livestock unpleasant odor among lower fatty acids. Excellent deodorant effect.
Of the two types of lower fatty acids mentioned above, isovaleric acid has a relevance to the human body as a odor of the sole portion, and normal butyric acid has a cause of bad breath.

Furthermore, the deodorizing effect of this antibacterial agent PR is not only due to odor components derived from humans, but also to trimethylamine (which is an osmotic pressure regulating component / trimethylamine-N-oxide contained in fish) that is a rotting odor of fish. The effectiveness was also shown (refer FIG.5 (e)).
Ammonia, hydrogen sulfide, isovaleric acid, normal butyric acid, and trimethylamine used in the experiment are all listed as substances subject to the Odor Control Law.

In addition, when preparing a virus inactivating active ingredient derived from soybean amino acid or a surfactant, a solution containing active water alone or a mixture of butylene glycol (or 2.7% alcohol) in active water is used as a diluent. Good.
By doing in this way, the permeability of the antibacterial agent PR is enhanced, and the virus inactivating effect, the antibacterial effect, and the deodorizing effect can be efficiently exhibited.

Next, operation | movement of the infectious disease prevention system 1 provided with the said structure is demonstrated.
As shown in FIG. 6, when a stepping operation is performed on the foot switch 7, the switch 7 is turned on and electric power for operation is supplied to the compressor 2 (step S1).

Then, the motor 21 (FIG. 3) of the compressor 2 operates.
In the compressor 2, when the piston 23 in the cylinder 22 moves in a direction to increase the volume inside the cylinder 22, the suction valve 25 opens inward and external air is taken into the cylinder 22 (step S2 in FIG. 6). ).

After the air is taken in, if the volume in the cylinder 22 is reduced by the piston 23, the air in the cylinder 22 is compressed, and the discharge valve 26 opens outward to discharge the compressed air to the outside of the cylinder 22. The
In this example, since the discharge valve 26 is connected to the air nozzle 28 through the air tube 27 (FIG. 2), compressed air is injected from the nozzle 28 (step S3 in FIG. 6). Then, the air compressed by the compressor 2 is sent into the mist generation chamber 4 in which the air nozzle 28 is inserted.

At this time, the antibacterial agent PR in the liquid tank 3 is sucked up from the suction port 312 of the straw 31 toward the discharge port 311 by the negative pressure action generated between the air nozzle 28 and the liquid straw 31 (step S4). .
The sucked-up antibacterial agent PR diffuses in the form of mist (in the form of minute droplets) from the discharge port 311 into the mist generation chamber 4.

Further, in the fog generating chamber 4, the compressed air blown from the air nozzle 28 is discharged from the floating droplet nozzle 41.
Therefore, the mist-shaped antibacterial agent PR is also discharged from the floating droplet nozzle 41 to the outside of the mist generation chamber 4 together with the compressed air (step S5).

Then, the mist-like antibacterial agent PR is sprayed to the user from the injection hole 62 of the columnar sprayer 6 through the guide tube 5 and the guide pipe 61 (step S6).
The antibacterial agent PR is also sprayed on footwear such as cuffs, apron / front apron, trouser hem and shoes worn by the user (FIG. 4).
Thus, when the user leaves the toilet, the antibacterial agent PR is sprayed to complete a series of operations for effectively disinfecting norovirus contaminants attached to the user.

As described above, according to the infection prevention system according to the present embodiment, the antibacterial agent PR is sprayed from the columnar sprayer 6 disposed so as to surround the foot switch 7 so that the antibacterial agent PR is It penetrates efficiently into the lower body, arms and hands of users who have left the toilet.
This makes it possible to “effectively prevent infectious diseases” caused by norovirus and the like when “users of facilities / equipment (especially toilets) shared by many people leave the facility”.

[Modification: Arrangement pattern of columnar sprayer]
In the infectious disease prevention system according to the above embodiment, as the arrangement pattern of the columnar sprayers 6, it is possible to install one columnar sprayer 6 at each vertex of the polygonal region.
In the example of FIG. 7A, one columnar sprayer 6 is arranged at three vertices of a triangular area (broken line portion of FIG. 7A), and in the example of FIG. One columnar sprayer 6 is disposed at each of the four apexes of the broken line portion (b).

It should be noted that the antibacterial agent injection direction (direction of the injection hole 62) of each columnar sprayer 6 is all directed toward the center of gravity G of the polygonal region, and the foot switch 7 is preferably installed near the center of gravity G (FIG. 8 ( b), see FIG. 8C).
By adopting such a configuration, the user is inevitably positioned in the vicinity of the above-mentioned center of gravity G when the foot switch 7 is depressed, so that the antibacterial agent PR from all the columnar sprayers 6 is used. This is because the spray is concentrated on the user and the disinfection effect on the virus contaminants attached to the user is improved.

[Modification: Enclosure of column sprayer]
In this infectious disease prevention system, you may comprise an enclosure by standing a board member between adjacent columnar sprayers 6 (FIG. 9 (a), FIG.9 (b)).
Thereby, it is possible to prevent the antibacterial agent PR sprayed on the human body / clothes from being scattered around the columnar sprayer 6.
Moreover, since the antibacterial agent PR stays in the enclosure by providing the enclosure, it can be expected that the antibacterial agent PR spreads throughout the whole body of the user of the system and the disinfection effect is enhanced.

[Modification: Column shape of column sprayer]
In the present infection prevention system, the overall shape of the columnar sprayer 6 is not limited to a linear shape, and any shape for enhancing the disinfection effect such as an L shape (see FIG. 10) or a U shape may be adopted.

[Modification: Columnar sprayer with wheels]
Furthermore, in this infection prevention system, you may provide a wheel (what is called a caster) in the bottom face part of the columnar sprayer 6. FIG.
In this way, when changing the installation location of the system, the burden of transportation work is greatly reduced.
In addition, since this system is intended for use in facilities that are shared by many people, such as toilets, the system itself, as well as the location where the system is installed (for example, the floor, etc.) can be relatively dirty. Conceivable.
If the columnar sprayer 6 is provided with wheels even when periodic (for example, daily level) cleaning is performed as such a countermeasure, the columnar sprayer 6 is moved once at the start of cleaning, and then the columnar sprayer 6 is moved after the cleaning is completed. The effort can be reduced when returning to the original position.

[Modification: Switch system for controlling power supply to the compressor]
In this infectious disease prevention system, it is possible to employ any type of switch as a switch that controls power supply to the compressor 2.
However, in consideration of the risk of spreading norovirus infection, it is desirable for the users of this system to be able to “switch on / off without touching directly”.
The switches that can be turned on and off by the user in a non-contact manner are not limited to the foot switch 7 illustrated in the above embodiment, but an “IC (Integrated Circuit) card reader 71 and a non-contact IC card 72”. It is also possible to adopt (FIG. 11).

When power supply control to the compressor 2 is performed using the IC card reader 71, when the user holds the non-contact type IC card 72 close to the IC card reader 71, the IC card reader 71 and the non-contact type are controlled. Short-distance wireless communication is performed between the IC cards 72.
When the IC card reader 71 detects the non-contact type IC card 72 by the wireless communication, the IC card reader 71 turns on the switch of the compressor 2.

When the system configuration shown in FIG. 11 is adopted, the switch portion is different from the configuration shown in FIG. 1 (the foot switch 7), but the configuration portion for spraying the antibacterial agent PR has the same configuration as FIG. Follow it.

In addition, when the introduction destination of the system 1A shown in FIG. 11 is a company or the like, “employee ID is composed of a non-contact type IC card 72” can be used to identify each employee individually. .
In this way, based on the reading history of the non-contact type IC card 72 by the IC card reader 71, “history of whether or not the employee has performed disinfection by the infectious disease prevention system 1A when using the toilet” is converted into electronic data. It is also possible to record.
For this reason, it can be expected that employees will be able to further promote thorough awareness of disinfection.

[Modification: Antibacterial component]
The antibacterial active ingredient of the antibacterial agent PR of this example is not limited to amino acids derived from soybeans, but is not virus-free, such as glycine cysteine, which is an amino acid that constitutes a protein component, or glycylglycine in which two molecules of glycine are peptide-bonded. Any plant- or animal-derived amino acid having an activating effect may be employed.
The antibacterial agent PR itself is prepared by blending a surfactant with this antibacterial active ingredient.
Glycine, cysteine, and glycylglycine also have a strong deodorizing effect, so even if the toilet user is attached with filth (feces or vomit) mixed with norovirus, the odor emitted from these filth Can be suppressed.

The present invention has been described above with reference to the embodiments, but the present invention is not limited to the above embodiments. Various modifications that can be understood by those skilled in the art can be made to the configuration and details of the present invention without departing from the gist of the present invention.
