そしてこの蒸発室13にはアルミニウム製で球形の粒体14が多数隙間無く詰め込まれて収容されており、上記メッシュ部材12にこの粒体14の径よりも目の細かい物を使用することで、粒体14が導入側通路7や排出側通路8には移動しないようになっている。
この粒体14は球形を有しているため、互いに隣接する粒体14と粒体14との間には空間が形成され、上記導入口6aから流入した気体はこれらの空間を通って排出口6bから排出されるようになっている。
ここで、この粒体14としては、伝熱性が高く、過酸化水素水のような腐食性の滅菌液体によって腐食しない素材であって、隣接させた時にそれらの間に空間が形成される形状を有するのが好ましい。上記アルミニウム製の球体の他にも、例えばステンレス製の球体、ガラスビーズ、砂利などを使用することができる。

そして配管17を圧縮部材19と押圧部材20との間に挟持した状態で、駆動手段21によって圧縮部材19の突起19aを容器16から蒸発器2に向けて移動させることで、配管17内の滅菌液体が蒸発器2に向けて送液されるようになっている。
Next, as shown in FIG. 1, the liquid supply means 3 includes a container 16 consisting of a bottle or bag filled with a sterilizing liquid made of hydrogen peroxide diluted to 35%, and the dripping of the container 16 and the evaporator 2. A pipe 17 communicating with the nozzle 9 and a liquid feed pump 18 provided in the middle of the pipe 17 for feeding a sterilizing liquid are provided.
The liquid feed pump 18 includes an endless compression member 19 having a plurality of protrusions 19a, a pressing member 20 that sandwiches the piping 17 between the compression member 19, and a driving unit 21 that circulates and moves the compression member 19. It is a peristaltic pump equipped with.
Then, in a state where the pipe 17 is sandwiched between the compression member 19 and the pressing member 20, the driving means 21 moves the protrusion 19 a of the compression member 19 from the container 16 toward the evaporator 2, thereby sterilizing the pipe 17. The liquid is sent toward the evaporator 2.

上記送気手段4は上記蒸発器2に向けて所定の圧力で気体を送気し、送気された気体は上記加熱手段5を通過する間に、当該加熱手段5によって所定の温度に加熱されるようになっている。
なお、これら送気手段4及び加熱手段5の詳細な構造は従来公知であるので、これ以上の説明を省略する。
The air supply means 4 supplies gas to the evaporator 2 at a predetermined pressure, and the supplied gas is heated to a predetermined temperature by the heating means 5 while passing through the heating means 5. It has become so.
In addition, since the detailed structure of these air supply means 4 and the heating means 5 is conventionally well-known, further description is abbreviate | omitted.

そして以上のような構成からなる滅菌蒸気発生装置1では、以下のようにして滅菌蒸気をアイソレータに送気するようになっている。
最初に、送気手段4より送気が開始され、送気された気体は加熱手段5によって70℃〜90℃に加熱されたのち、導入側通路7を介して蒸発器2の蒸発室13内へと供給される。
蒸発室13内では、加熱された気体が各粒体14と粒体14との間の空間を通過して排出口6bより排出され、排出側通路8を介してアイソレータへと排出される。このとき、加熱された気体が粒体14と粒体14との間を通過することによって上記粒体14が加熱され、所要の時間が経過すると全ての粒体14がこの気体と同じ温度にまで加熱される。
And in the sterilization vapor | steam generator 1 which consists of the above structures, sterilization vapor | steam is supplied to an isolator as follows.
First, air supply is started by the air supply means 4, and the supplied gas is heated to 70 ° C. to 90 ° C. by the heating means 5, and then in the evaporation chamber 13 of the evaporator 2 through the introduction side passage 7. Supplied to.
In the evaporation chamber 13, the heated gas passes through the space between each particle 14 and the particle 14, is discharged from the discharge port 6 b, and is discharged to the isolator through the discharge side passage 8. At this time, the heated gas passes between the particles 14 and the particles 14 so that the particles 14 are heated, and when the required time elapses, all the particles 14 reach the same temperature as the gas. Heated.

このようにして粒体14が加熱されると、液体供給手段3の送液ポンプ18が作動し、容器16から蒸発器2の滴下ノズル9まで所定量の滅菌液が送液され、滴下ノズル9から蒸発室13内の粒体14に滴下される。
滴下された滅菌液体は滴下ノズル9の直下に位置する粒体14に付着した後、下方の粒体14や、気体の流れによって排出口6b側の粒体14に伝いながら広がってゆく。
そして粒体14の表面に付着した滅菌液体は粒体14及び加熱された気体の熱によって蒸発し、蒸発によって得られた滅菌蒸気は送気手段4による気体の流れに乗って、各粒体14と粒体14との間を通って排出口6bからアイソレータへと排出される。
When the granule 14 is heated in this manner, the liquid feeding pump 18 of the liquid supply means 3 is operated, and a predetermined amount of sterilizing liquid is fed from the container 16 to the dropping nozzle 9 of the evaporator 2. To the particles 14 in the evaporation chamber 13.
The dropped sterilized liquid adheres to the granules 14 located immediately below the dropping nozzle 9 and then spreads while being transmitted to the granules 14 on the lower side and the granules 14 on the discharge port 6b side by the gas flow.
And the sterilization liquid adhering to the surface of the granule 14 evaporates by the heat | fever of the granule 14 and the heated gas, The sterilization vapor | steam obtained by evaporation rides on the gas flow by the air supply means 4, and each granule 14 And the particles 14 are discharged from the discharge port 6b to the isolator.

このように、本実施例の滅菌蒸気発生装置1によれば、蒸発室13内に表面積の大きい粒体14を収納しているので、付着した滅菌液体はこの粒体14上に薄く広がり、加熱された粒体14および加熱された気体によって速やかに蒸発し、効率的に滅菌蒸気を得ることができる。
また上記粒体14に伝熱性の高いアルミニウムを用いているので、これらの粒体14は速やかに加熱された気体と同じ温度まで過熱され、滅菌蒸気発生装置1の作動後、早期に滅菌蒸気を得ることができる。
さらに、滴下ノズル9の位置をハウジング6の上方であって、なおかつ導入口6aの近傍としているため、滴下された滅菌液体が気体の流れによって排出口6b側に移動しても、排出口6bに達するまでの間に全ての滅菌液体を蒸発させることができ、蒸発しなかった滅菌液体がアイソレータに流入してしまうような事はない。
しかも、本実施例の蒸発器2は円筒状のハウジング6の両端に導入側通路7及び排出側通路8を配しているだけであるため、構成が容易で部品点数が少なく、低コストに滅菌蒸気発生装置1を得ることができ、また配管の自由度も高いという利点がある。
Thus, according to the sterilization steam generator 1 of the present embodiment, the particles 14 having a large surface area are accommodated in the evaporation chamber 13, so that the attached sterilized liquid spreads thinly on the particles 14 and is heated. The evaporated particles 14 and the heated gas quickly evaporate, and sterilized vapor can be efficiently obtained.
Moreover, since aluminum with high heat conductivity is used for the granule 14, the granule 14 is quickly heated to the same temperature as the heated gas, and sterilization steam is quickly generated after the operation of the sterilization steam generator 1. Can be obtained.
Furthermore, since the position of the dropping nozzle 9 is above the housing 6 and in the vicinity of the inlet 6a, even if the dropped sterilized liquid moves to the outlet 6b due to the flow of gas, All the sterilizing liquid can be evaporated until it reaches, and the sterilizing liquid that has not evaporated does not flow into the isolator.
In addition, since the evaporator 2 of this embodiment is merely provided with the introduction side passage 7 and the discharge side passage 8 at both ends of the cylindrical housing 6, the structure is easy, the number of parts is small, and the sterilization is low. There is an advantage that the steam generator 1 can be obtained and the degree of freedom of piping is high.

また、本実施例の滅菌蒸気発生装置1は少量の滅菌蒸気で滅菌可能な比較的容量の小さいアイソレータを滅菌するのに好適となっている。
すなわち、本実施例の滅菌蒸気発生装置1であれば、従来備えていた蒸発器2を直接加熱するための加熱器を省略した構成であっても、少量の滅菌液体、具体的には1.0g/分以下の滴下量であれば十分に蒸発させることができる。
従って、少量の滅菌液体を蒸発させるのであれば、加熱器によって蒸発器を加熱する必要がなく、加熱器を設けない分だけ装置自体のコストが低減し、それに伴って蒸発器2を加熱するためのランニングコストも削減することが可能となる。
換言すると、大容量のアイソレータのように多量の滅菌蒸気を必要とする場合には、本実施例の滅菌蒸気発生装置1に対し、上記蒸発器2に粒体14を加熱するための加熱器を付加して設ければよく、この加熱器によって粒体14を加熱すれば、大量の滅菌液体であっても本実施例の滅菌蒸気発生装置1と同様、効率的に蒸発させることが可能となる。
In addition, the sterilization steam generator 1 of this embodiment is suitable for sterilizing an isolator with a relatively small capacity that can be sterilized with a small amount of sterilization steam.
That is, in the case of the sterilization steam generator 1 of the present embodiment, a small amount of sterilizing liquid, specifically 1. A dripping amount of 0 g / min or less can be sufficiently evaporated.
Therefore, if a small amount of sterilizing liquid is evaporated, it is not necessary to heat the evaporator with a heater, and the cost of the apparatus itself is reduced by the amount not provided with the heater, and accordingly the evaporator 2 is heated. The running cost can be reduced.
In other words, when a large amount of sterilization steam is required, such as a large-capacity isolator, a heater for heating the particles 14 to the evaporator 2 is provided to the sterilization steam generator 1 of this embodiment. If the granule 14 is heated by this heater, even a large amount of sterilized liquid can be efficiently evaporated as in the case of the sterilization vapor generator 1 of the present embodiment. .
