DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner capable of mixing sterilizing and deodorizing gas for sterilizing and deodorizing and an infection control system for a treatment room or an autopsy room equipped with a waste liquid treatment system. is there.

[0002]

2. Description of the Related Art In an operating room where various operations of internal medicine and surgery are performed, and in a treatment room where dissection or correction of a corpse is performed (emblemming), medical personnel and staff in charge are protected from various bacteria and viruses, and It is necessary to prevent a situation in which various bacteria and viruses flow out of the facility at the time of entering and leaving these workers and through processing of clothes, etc., and a treatment room / dissection room air cleaning function is required. In addition, the operating table, surgical instruments, operating room, treatment table, treatment room, treatment instruments, etc., must be completely cleaned and disinfected and always kept clean. Since wastewater from such washing treatment and wastewater discharged from various treatments of living bodies and corpses may contain substances that are undesirable for the surrounding environment, wastewater treatment systems for treatment rooms and dissection rooms Is required.

There are various chemicals effective for sterilizing and deodorizing indoor air, and these chemicals are used as they are or in the form of a diluted solution or powder using a spray or atomizer. However, with such a method, it is difficult to sterilize and deodorize a desired space such as a room uniformly and reliably. In particular, there is a concern that the use of powerful drugs may adversely affect the human body. In addition, in an environment where medical staff and treatment staff stay for a long time, sterilization can be performed safely, easily and stably through indoor air, clothing, various tools and instruments while eliminating adverse effects on the human body. A method and an apparatus that can perform deodorization and the like are desired.

Further, in order to treat waste liquid from operating rooms, treatment rooms, dissection rooms, etc. which may contain various bacteria and viruses, the waste liquid can be reliably sterilized and discharged to the outside as sterile. It is necessary to settle and separate into a liquid and a solid and discard it. However, although the wastewater treatment method by the ordinary activated sludge method removes pollutants from ordinary wastewater,
A bactericidal effect that satisfies the viewpoint of biohazard cannot be expected.

[0005] Therefore, medical equipment, bedding, clothing,
In addition, for the sterilization and disinfection of the whole room, a solution obtained by evaporating a stabilized chlorine dioxide (ClO2) solution is widely used. It has long been known that stabilized chlorine dioxide has a bleaching action, and many methods have been used for its production. However, high-concentration chlorine dioxide produced industrially becomes a strong oxidizing agent, reacting with other substances to generate high-concentration chlorine, and the danger of explosion cannot be ruled out. Therefore, a 5% aqueous solution of a stabilized aqueous solution of chlorine dioxide, which has a low risk and is easy to handle, is commercially available and is appropriately diluted according to the intended use.

[0006] Chlorine dioxide gas obtained by vaporizing a stabilized chlorine dioxide solution has various effects such as high sterilization, deodorization, and disinfection by being brought into contact with an object despite being safe without an intense irritating odor. Demonstrate. Its effect on sterilization, deodorization, etc. against various bacteria, molds and pathogenic fungi is remarkable, and the object can be achieved in a short time. In addition, it has a remarkable deodorizing effect, has a large deodorizing effect against chemical substance odor and putrefaction odor, and further has an effect of preventing the propagation of microorganisms that are the cause of the offensive odor.

[0007] Since chlorine dioxide having such excellent characteristics is usually an aqueous solution, care must be taken in handling such as transportation, handling and replenishment, and there is a drawback that the vaporizer becomes complicated. Such a stabilized aqueous solution of chlorine dioxide may be adsorbed on a porous material such as zeolite and used as a powder or granular material.

In order to solve such a problem, the present applicant uses a gel medicine which is highly safe to handle and removes stabilized chlorine dioxide gas by heating with a heating means (Japanese Patent Application No. Hei 10-1998). No. 76467), and an air conditioner equipped with a chlorine dioxide gas generator at a hot / cold air discharge port for air conditioning (Japanese Patent Application No. 11-11). It is necessary to address the so-called biohazard berries that integrate the inventions of these applications to solve the problems related to the prior art and prevent the danger of infecting humans and animals with bacteria and viruses and spreading to the surrounding environment. Have been.

[0010]

SUMMARY OF THE INVENTION It is an object of the present invention to provide air for blowing out temperature-regulated air containing an appropriate amount of stabilized chlorine dioxide gas into a treatment room / dissection room and / or a space adjacent to the entrance / exit side thereof. After injecting an appropriate amount of a stabilized aqueous solution of chlorine dioxide into the wastewater treatment device for treating the wastewater from the treatment room, the dissection room, and the like, sterilizing the solid-liquid separation, An infection prevention system for a treatment room, an autopsy room, or the like, provided with an infection prevention waste liquid treatment device for performing and discharging the respective solutions.

An object of the present invention is to provide a high-efficiency particulate air (High Eff.) Which is antibacterial for an outside air inlet and an outlet outside the air conditioner installed in the treatment room / dissection room.
iciency Particulate Air, abbreviated as antibacterial HEPA)
The problem can be solved more advantageously by an infection prevention system for a treatment room / dissection room or the like to which a filter is added.

An object of the present invention is to provide a treatment room / anatomy in which a vaporized component discharge port is provided at an appropriate portion such as a raw water tank and a subsequent treatment tank of the above-mentioned infection control waste liquid treatment apparatus, and an antibacterial HEPA filter is added to the discharge port. Infection control system for rooms
It is more advantageously solved.

It is an object of the present invention to provide an apparatus for treating wastewater for preventing infection, which comprises, in addition to the treatment with the stabilized chlorine dioxide solution, a strong acid treatment with sulfuric acid, a neutralization treatment with caustic soda, and a coagulated solid-liquid separation treatment. A further advantageous solution is provided by an infection control system for treatment rooms, dissection rooms, etc., having a processing step.

According to the infection control system for the treatment room / dissection room according to the present invention, the stabilized chlorine dioxide is used for the inside of the treatment room / dissection room, etc., and the space which must pass when workers enter and exit. Temperature-regulated air containing an appropriate amount of gas is discharged from the air conditioner. The stabilized chlorine dioxide gas component contained in the temperature-regulated air discharged from the air conditioner also sterilizes workers entering and exiting the space, their clothes, used equipment, and required articles and materials. Therefore, undesired situations such as infection of workers and third parties, invasion and diffusion of bacteria, viruses and other unwanted microorganisms by clothes, equipment and tools, and spread by indoor floating bacteria are eliminated. . It should be noted that invasion and diffusion of airborne bacteria through ventilation means such as a treatment room and an autopsy room are prevented by ventilation means provided with an antibacterial HEPA filter.

According to the present invention, the waste liquid discharged from the treatment room / dissection room where the risk is highest is directly added with a stabilized chlorine dioxide solution exhibiting an extremely high bactericidal activity, or sulfuric acid or other strong acid is used. Addition during processing ensures sterilization. However, the treated waste liquid up to this stage shows strong acidity, so the neutralizing solution corresponding to the strong acid solution,
For example, a neutralization treatment step of adding caustic soda is performed.
The waste liquid that has passed through each step of sterilization treatment and neutralization treatment through such a process is subjected to agglomerated solid-liquid separation by a well-known process such as sedimentation and centrifugation, and the treated liquid is discharged to the outside. The coagulated solids taken out are carried out for appropriate post-treatment such as incineration and burying similar to similar exhausts.

At appropriate portions in the waste liquid treatment process having the above structure,
Usually, a mechanism for discharging vaporized components is added. However, by disposing an antibacterial HEPA filter in such a vaporized component discharging mechanism, diffusion of floating bacteria can be prevented.

In the present invention, the treatment room
The treatment room and the air conditioner and the ventilation device in the dissection room
Not only the dissection room itself, but also workers and third parties, their clothing, direct transmission of bacteria, viruses, and the like via tools, tools, materials, etc., and the spread of floating fungi are prevented. In addition, sterilization treatment with a stabilized chlorine dioxide solution is carried out prior to and / or simultaneously with treatment with a strong acid liquid, especially for waste liquids with a high risk of leakage such as bacteria and viruses.
Unwanted diffusion is prevented. In addition, airborne bacteria which may be diffused by being mixed into the vaporized components are collected by the antibacterial HEPA filter installed in the vaporized component discharge mechanism, and are prevented from being diffused into the atmosphere. These effects combine to form an excellent biohazard system, thereby preventing infections to workers and others and adverse effects associated with the spread to the surrounding environment.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Prior to specifically disclosing an infection prevention system for a treatment room, an anatomical room, and the like according to the present invention, drugs used in the present invention will be described. In the present invention, the stabilized chlorine dioxide gas and the aqueous solution are applied as agents having a sterilizing property, a sterilizing property, a disinfecting property, a deodorizing property and the like. In addition, other conventionally used germicides and the like can be used together, and are not particularly excluded.

Therefore, stabilized chlorine dioxide as a main component will be described. There is no particular problem with the stabilized chlorine dioxide aqueous solution since it is stored in a tank and an appropriate amount may be discharged and added as needed. However, with regard to the generation of stabilized chlorine dioxide gas mixed when releasing temperature-controlled air into a room, it is more advantageous to evaporate the aqueous solution as a gel than to evaporate an aqueous solution in terms of stability and sustainability. It is possible that As a chemical property of chlorine dioxide, it reacts strongly with the double bond part and the benzene nucleus,
In addition, it is known that it also reacts with cyanide, hydrogen sulfide, protein, etc., but hardly reacts with saturated fatty acids or unsaturated fatty acids. Utilizing such a property, a stabilized chlorine dioxide aqueous solution is prepared by using a gelling agent obtained by mixing a saturated fatty acid such as stearic acid and palmitic acid with an unsaturated fatty acid such as oleic acid and linoleic acid, and gelatin, and gelatin. Can be gelled.

The rate of vaporization from the gel-stabilized chlorine dioxide can be adjusted by the amount of ethyl alcohol contained in the gelling agent and the evaporation area of the vessel, but naturally has a significant effect on the rate of the vaporization reaction. It also depends on the amount of UV irradiation and the heating temperature. In addition, stabilized chlorine dioxide is pH
Although the pH varies depending on the degree, the pH 9 is most stable.
It is desirable to keep to the extent.

The gelled stabilized chlorine dioxide is advantageous for storage, transportation, handling, etc., as compared with an aqueous solution.
It can be used safely in small containers. In the application to the air conditioner of the present invention, it is preferable that the stabilized chlorine dioxide gelled in this way is used by filling it in a cartridge type container rather than the stabilized chlorine dioxide aqueous solution.

Next, embodiments of the present invention will be described with reference to the accompanying drawings. FIG. 1 shows an example of the basic configuration of an infection prevention system for a windowless treatment room / dissection room or the like according to the present invention. Reference numeral 10 denotes a treatment room / dissection room, in which other equipment and fixtures installed on the floor, an operating table (treatment table), and the like are omitted. In the treatment room / dissection room 10, an adjacent space (biohazard room) 20 connected to the entrance 12 is formed. Treatment room / dissection room 10
Anyone who enters or exits is configured to pass. If other doorways are formed on different surfaces,
Each requires an adjacent space (biohazard room) 20.

An air conditioner 22 is installed in the adjacent space (biohazard chamber) 20. Stabilized chlorine dioxide (ClO 2) is provided in the air passage near the air outlet.
₂ ) The ClO ₂ gas is supplied from the gas generating unit 24 and is mixed in an appropriate amount in the discharge air. This air conditioner 22
Is blown out from the outlet 26 into the biohazard chamber 20. The temperature-controlled air mixed with the ClO ₂ gas is supplied to the treatment room / dissection room 1 similarly.
The air is also discharged through the outlet 28 so that the atmosphere in these rooms is suitable for sterilization, deodorization, and the like. The installation location of the air conditioner 22, the outlets 26, 2
The installation position and number of 8 etc. are merely examples.

The treatment room / dissection room 10 is provided with an outside air intake port 14, an exhaust port 16 and the like as necessary.
A filter).

The treatment room / dissection room 10 generally refers to an operating room, a dissection room, a corpse rehabilitation room, or the like in a medical institution. Waste liquid from this room is sent to the outside through a waste liquid discharge port 18. .

In this embodiment, the treatment room
The dissection room 10 is provided with a waste liquid treatment device 30, which is configured to process the waste liquid sent from the waste liquid discharge port 18 of the treatment room / dissection room 10.

An embodiment of such a waste liquid treatment apparatus 30 is as follows.
It comprises a raw water tank 32, a waste liquid treatment tank 34, and a stabilized chlorine dioxide aqueous solution tank 36. The waste liquid treatment tank 34 is also used with a conventional waste liquid treatment means 38 for adding a strong acid treatment liquid, a neutralizing agent, and the like, which are conventional waste liquid treatment means. In this embodiment, sulfuric acid and caustic soda are used as these means, but other means used for waste liquid treatment may be used.

In this case, means for releasing the vaporized components of the waste liquid into the atmosphere are provided at appropriate places in the waste liquid treatment device 30. These discharge means are respectively provided with a HEPA filter 40.
It is desirable to arrange. In this embodiment, the raw water tank 32

The operation and action of the infection prevention system for the treatment room / dissection room and the like formed as described above will be disclosed below.
In this system, when performing various treatments such as surgery, anatomy, corpse correction, etc.
It is intended to appropriately treat bacteria, viruses, and other microorganisms that may have a bad influence on workers, third parties, or the surrounding environment by separating them from liquids and solids. Therefore, the target treatment room / dissection room or the like is configured not to be discharged or diffused as it is outside the room.

Workers who enter or leave the treatment room or dissection room or the like pass through the biohazard room, which is an adjacent space, every time they enter or exit. In this biohazard chamber, temperature-regulated air mixed with an appropriate amount of stabilized chlorine dioxide gas that is effective for sterilization and deodorization is constantly discharged. Therefore, the indoor atmosphere has extremely reduced the presence of bacteria and viruses, and is in a state where at least no floating bacteria and the like exist. In addition, since a hand-washing device, a shower device, and the like, which are not particularly disclosed because they are not the subject of the present invention, are usually provided outside the biohazard room, they are combined with these facilities for workers or for workers. Thus, infection to third parties and other inconvenient situations are avoided.

Further, similarly to the biohazard chamber, the treatment room, the dissection room and the like are constantly discharged with temperature-controlled air containing an appropriate amount of stabilized chlorine dioxide gas, so that the atmosphere is similarly maintained. Therefore, the presence of floating bacteria and the like is reduced as much as possible. In some cases, it is necessary to take in outside air into the treatment room, dissection room, etc. and exhaust indoor air.
Equipped with a filter to prevent inhalation of bacteria and fungi from outside and discharge and diffusion from inside the room.

The discharge of liquids, fluids, etc. from the treatment room, dissection room, etc. is performed only through the discharge port leading to an external waste liquid treatment device. In this waste liquid treatment apparatus, in addition to the usual waste liquid treatment using a strong acid or a neutralizing agent, a sterilization treatment in which a stabilized chlorine dioxide aqueous solution is mixed is performed. Therefore, the presence of undesired bacteria and viruses is extremely reduced. Thereafter, conventional solid matter such as precipitation, centrifugation, filtration, etc.
The liquid is separated into a clear processed liquid and a solid by a liquid separating means.

The separated liquid thus separated no longer contains any harmful components to humans and animals, and does not adversely affect the surrounding environment. Further, the separated solid matter is incinerated in the same manner as in the same waste treatment. In addition,
An HEPA filter for collecting undesired components in the vaporized components is disposed at an appropriate place in the waste liquid treatment device, and prevents diffusion into the atmosphere.
