2. Description of the Related Art Recently, the problem of nosocomial infection has been taken up in the news, etc., but there are many people who think that the countermeasures are delayed in the treatment rooms, waiting rooms, nurse centers and the like in hospitals. It is said that the cause of the infection is airborne pathogens adhering to dust of several μm to several tens of μm, and it is considered that the most effective countermeasure is to remove the dust adhering to these airborne pathogens. There is also a place where a filter with a fan is installed on the wall that constitutes the room, and the filter collects dust with airborne pathogens attached.

However, since the corners and many other parts are stagnant in the room, the above-mentioned method cannot effectively remove the dust adhered by the airborne pathogens.
It was just a rest.

Therefore, there is a long-awaited expectation that a system effective as a preventive measure against nosocomial infections will be developed among hospital personnel and inpatients.

[0005] It should be noted that such demands are not limited to those involved in hospitals, but also among the care recipients and their families who need home care.

[0006]

Therefore, it is an object of the present invention to provide a system for collecting indoor airborne pathogens, which is capable of effectively removing dust to which airborne pathogens adhere from a room (small room).

DETAILED DESCRIPTION OF THE INVENTION The present invention will be described below with reference to the drawings showing the embodiments. [Embodiment 1] FIG. 1 is a front view of a system S for collecting indoor airborne pathogens according to an embodiment of the present invention, and FIG. 2 is a swirling air flow in which a swirling flow generating means 3 flows along a side wall 21 in a small chamber 2. 9 shows the state in which 9 is raised. (Regarding Configuration of Indoor Airborne Pathogen Collection System S) This indoor airborne pathogen collection system S forms a small room 2 for performing dental treatment in a room 1 of a dental clinic, as shown in FIG. At the same time, a portion of the chamber 1 other than the small chamber 2 is used as a waiting chamber 2 ', a swirling flow generating means 3 is provided in an upper portion of the small chamber 2, and a filter 4 is provided in a lower portion thereof.

The small chamber 2 is a floor 1 of the chamber 1, as shown in FIG.
0 is installed on the side wall 21 and a ceiling plate 20 having an air inflow hole 20a and a side wall 21 and a door (not shown) is formed on the side wall 21. The small chamber 2 has a structure in which air does not flow in or out except through the air inflow hole 20a and the filter 4.

As shown in FIG. 1 and FIG. 2, the swirling flow generating means 3 is installed in the portion of the ceiling plate 20 where the air inflow hole 20a is provided, and takes in the air from the waiting chamber 2'and the small chamber 2 '. Swirling airflow 9 flowing along the side wall 21 in
(For example, a slow flow velocity of about 0.1 to 0.5 m / sec) is generated. In this embodiment, the swirl flow generating means 3 employs a rotary vane type.

The filter 4 is a so-called sterilizing filter which uses a filter paper to which silver or enzyme functioning as a sterilizing agent is attached. As shown in FIG. 1, the air suction port is at the lower part of the small chamber 2 and the air discharge port. Are arranged in the lower part of the waiting room 2 ', respectively. The filter 4 has a built-in fan for sucking and discharging air. (Regarding Function of Collection System S of Indoor Airborne Pathogenic Bacteria) In FIG. 1, pathogenic bacteria in the oral cavity are discharged from the mouth of the patient who is receiving treatment in the small chamber 2 and float in the small chamber 2 to enter the small chamber 2. It adheres to the existing minute dust (mainly floating dust).

On the other hand, the swirling flow generating means 3 generates the swirling airflow 9 so as to flow along the side wall 21, and there is no stagnant portion in the entire small chamber 2. That is, the swirling airflow 9 generated by the swirling flow generating means 3 does not allow dust adhering to pathogenic bacteria to stagnant at the corners or corners of the small chamber 2.

Therefore, the dust with the pathogenic bacteria attached thereto is collected by the filter paper to which silver or enzyme is attached when passing through the filter 4, and the air passing through the filter paper is kept in the waiting room 2'with almost no pathogenic bacteria present. It is discharged to the bottom. Then, the air discharged to the lower part of the waiting chamber 2'is blown into the small chamber 2 again by the swirling flow generating means 3 as the swirling air flow 9. In the chamber 1, the air constantly circulates in the waiting chamber 2'and the small chamber 2, and the pathogenic bacteria in the oral cavity from the mouth of the patient undergoing treatment in the small chamber 2 are always collected by the filter 4. In addition, the pathogenic bacteria collected together with the dust by the filter paper die over time due to the sterilizing power of silver or enzyme.

As described above, a patient waiting in the waiting room 2'can avoid nosocomial infection. [Embodiment 2] The system S for collecting indoor airborne pathogens of this embodiment is formed so as not to infect a family member or the like living together with the illness of the care recipient, and is intended for home care.

In this system S for collecting indoor airborne pathogens, in order to easily install the small chamber 2, as shown in FIG. 3, the ceiling which constitutes the small chamber 2 via the chain 5 on the ceiling 11 of the chamber 1. The board 20 is suspended, and a transparent vinyl curtain serving as the side wall 21 is suspended on the ceiling board 20. In addition, this small chamber 2 has an air inflow hole 2
0a and the filter 4 so that air does not enter and exit between the ceiling plate 20 and the vinyl curtain serving as the side wall 21, and the lower end of the vinyl curtain is placed on the floor 10 within a relatively long range. I'm crawling.

The swirling flow generating means 3 and the filter 4 have the same structure as in the first embodiment.

Therefore, it is clear that this indoor floating pathogen collecting system S also has the same function as that of the first embodiment. [Other Embodiments]. In the above embodiment, the small chamber 2 is formed in the chamber 1, and the swirl flow generating means 3 and the filter 4 are provided in the small chamber 2, but the present invention is not limited to this. That is, a swirling air flow 9 that flows along the side wall surface of the chamber is generated by the swirling flow generating means 3 installed in the upper region of the chamber 1, and the inside of the chamber 1 is moved by the filter 4 installed in the lower part of the chamber 1. It is possible to collect dust to which airborne pathogens adhere. The air discharged from the filter 4 may be discharged outside the chamber 1. ． Instead of the above embodiment, the present invention can be applied to hospitals other than dental clinics, treatment rooms, waiting rooms, nurse centers, and the like. ． In place of the swirl flow generating means 3 of the above embodiment, the small chamber 2
As shown in FIG. 4, an air ejector 31 connected to an air supply device 30 such as a compressor is installed in the upper four corners of the air ejector 31, and air is ejected from the air ejector 31 in a direction indicated by a thick arrow to generate a swirling air flow. 9 may be generated. The air ejector 31 may be installed at two opposing corners of the four corners of the chamber 1 (small chamber 2). ． In the above-described embodiment, the filter 4 is a so-called sterilizing filter formed by using a filter paper to which silver or enzyme that functions as a bactericide is attached, but the present invention is not limited to this, and silver or enzyme that functions as a bactericide on the filter paper is used. May not be attached. In this case, the filter paper of the filter is replaced at regular intervals and the used filter paper is incinerated.
