Abstract
Description
本発明は、解剖実習室における解剖台において、ホルマリンから発生するホルムアルデヒドガス等の有害なガスの換気を行なう解剖台換気システムに関する。 The present invention relates to a dissecting table ventilation system for ventilating harmful gases such as formaldehyde gas generated from formalin in an dissecting table in an anatomical training room.
解剖実習において、一般に、検体の腐敗を防止するため、ホルマリンを検体に注入したり検体をホルマリンに浸したりしている。検体を解剖する際、そのホルマリンからホルムアルデヒドが発生するため、解剖作業者に大変有害であることが問題になっていた。 In the anatomical training, generally, formalin is injected into the specimen or the specimen is immersed in formalin to prevent the specimen from being corrupted. When a specimen is dissected, formaldehyde is generated from the formalin, which is problematic because it is very harmful to the dissection operator.
そこで、従来、図９に示すように解剖実習室の全体換気を行ったり、解剖台の局所排気（図１０及び特許文献１〜３参照）を行ったりしている。 Therefore, conventionally, as shown in FIG. 9, the entire anatomical training room is ventilated or the anatomical table is locally ventilated (see FIG. 10 and Patent Documents 1 to 3).
しかし、解剖実習室を全体換気するだけでは、ホルムアルデヒドが解剖台上の検体から気化するため、解剖台端で作業する解剖作業者の頭部近傍でのホルムアルデヒド濃度を規定値である０．１ｐｐｍ未満まで下げられない。 However, since formaldehyde is vaporized from the specimen on the dissection table simply by ventilating the entire dissection laboratory, the formaldehyde concentration near the head of the dissection operator working on the dissection table end is less than the specified value of 0.1 ppm. It cannot be lowered.
また、図１０に示すようなプシュプル換気方式では、解剖作業者が作業する際、検体を覆っている水平層流を遮るため、検体から気化しているホルムアルデヒドが、解剖台の外へ拡散する。そのため、解剖作業者の頭部近傍でのホルムアルデヒド濃度を規定値（０．１ｐｐｍ未満）まで下げられない。 Further, in the push-pull ventilation system as shown in FIG. 10, when a dissecting operator works, the horizontal laminar flow covering the specimen is blocked, so that formaldehyde vaporized from the specimen diffuses out of the dissection table. Therefore, the formaldehyde concentration in the vicinity of the dissection operator's head cannot be lowered to a specified value (less than 0.1 ppm).
このように、解剖作業者の頭部近傍でのホルムアルデヒド濃度が規定値（０．１ｐｐｍ未満）まで下げられ、かつ作業性の良い解剖台換気システムが求められている。 Thus, there is a need for an anatomical table ventilation system in which the formaldehyde concentration in the vicinity of the dissection operator's head is lowered to a specified value (less than 0.1 ppm) and the workability is good.
本発明は、上記のような従来技術の課題を解決するもので、その目的は、解剖実習室内及び解剖台端の解剖作業者の頭部近傍でのホルムアルデヒド濃度を規定値である０．１ｐｐｍ未満まで下げることができ、かつ作業性が良い解剖台換気システムを提供することにある。 The present invention solves the problems of the prior art as described above, and its purpose is to reduce the formaldehyde concentration in the anatomy training room and in the vicinity of the anatomical operator's head near the anatomical table edge to a specified value of less than 0.1 ppm. An object of the present invention is to provide a dissecting table ventilation system that can be lowered and has good workability.
上記の目的を達成するために、請求項１の発明は、解剖台の検体載置台の上方長手方向に、多数の小孔からの空気の浸み出しにより微風流を発するソックスダクトを設置し、前記解剖台の前記検体載置台に、検体周囲の空気を吸引する排気口を設け、前記ソックスダクトの小孔から前記解剖台に向けて垂直落下方向に対して擬似層流を形成し、この層流を前記排気口より排気することを特徴とする。 In order to achieve the above object, the invention of claim 1 is provided with a sock duct that emits a micro wind flow by leaching of air from a large number of small holes in the upper longitudinal direction of the specimen mounting table of the dissection table, The specimen mounting table of the dissection table is provided with an exhaust port for sucking air around the sample, and a pseudo laminar flow is formed in the vertical drop direction from the small hole of the sock duct toward the dissection table. The flow is exhausted from the exhaust port.
以上の態様では、解剖台換気システムでは、ソックスダクトの小孔から浸み出す微風速の空気により、解剖台に向けて垂直落下方向に擬似層流を形成する。そして、このソックスダクトからの擬似層流で解剖台を包み、同時に解剖台の検体載置台において、検体を包み込みながら検体に染み込んだホルマリンから発生するホルムアルデヒドを含んだ空気を、検体載置台の周囲に設けられた排気口から排出する。 In the above aspect, in the dissecting table ventilation system, a pseudo laminar flow is formed in the vertical drop direction toward the dissecting table by the air at a low wind speed that permeates from the small hole of the sock duct. Then, the anatomical table is wrapped with a pseudo laminar flow from the sock duct, and at the same time, air containing formaldehyde generated from formalin soaked in the sample while wrapping the sample is wrapped around the sample mounting table. Exhaust from the exhaust port provided.
このように、解剖作業者が作業中に部分的に擬似層流を遮っても、解剖台の検体載置台周囲の排気孔からの排気があるため、検体から発生するホルムアルデヒドが解剖台の外に拡散することがない。これにより、解剖実習室内及び解剖台端の解剖作業者の頭部近傍でのホルムアルデヒド濃度を規定値である０．１ｐｐｍ未満まで下げることができ、かつ作業性が良い解剖台換気システムを提供することが可能となる。 In this way, even if the dissection operator partially blocks the pseudo laminar flow during work, there is exhaust from the exhaust holes around the specimen mounting table of the dissection table, so that formaldehyde generated from the sample is outside the dissection table. Does not spread. Accordingly, it is possible to reduce the formaldehyde concentration in the anatomy training room and in the vicinity of the head of the dissecting table at the dissecting table end to below the specified value of 0.1 ppm, and to provide a dissecting table ventilation system with good workability. It becomes possible.
請求項２の発明は、請求項１記載の発明において、前記解剖台の前記検体載置台周囲には、前記検体載置台の上方に向かってガス拡散防止板が設けられたことを特徴とする。
以上の態様では、検体からのホルムアルデヒドが解剖台の外に拡散することを効果的に防止することができるとともに、ガス拡散防止板は柔らかく簡単に変形可能に構成することで、解剖作業者の作業性を妨げることがない。
The invention of claim 2 is characterized in that, in the invention of claim 1, a gas diffusion prevention plate is provided around the specimen mounting table of the dissecting table toward the upper side of the specimen mounting table.
In the above aspect, the formaldehyde from the specimen can be effectively prevented from diffusing out of the dissection table, and the gas diffusion prevention plate is configured to be soft and easily deformable so that the work of the dissection operator can be performed. Does not interfere with sex.
請求項３の発明は、請求項１又は２記載の発明において、前記ソックスダクトは、その断面が半円形状で、円弧部分を前記解剖台側に向けて設置されたことを特徴とする。
以上の態様では、設置する解剖室のハード的制約に対応することが可能となる。
The invention of claim 3 is the invention of claim 1 or 2, characterized in that the sock duct is semicircular in cross section and is arranged with the arc portion facing the dissecting table.
In the above aspect, it becomes possible to cope with the hardware restriction of the dissection room to be installed.

本発明を実施するための形態について、本発明の解剖台換気システムを用いた例を説明する。
［１．本実施形態］
［１−１．構成及び作用効果］
図１は、本実施形態の解剖台換気システム１の全体構成を示す側面模式図（ａ）と、正面模式図（ｂ）と、解剖台の平面図（ｃ）である。この図に示すように、本実施形態の解剖台換気システム１は、解剖台２と、この解剖台２の検体載置台４の上方に、長手方向に向かって設置されたソックスダクト５とを備える。
About the form for implementing this invention, the example using the dissecting table ventilation system of this invention is demonstrated.
[1. This embodiment]
[1-1. Configuration and effect]
FIG. 1 is a schematic side view (a), a schematic front view (b), and a plan view (c) of the dissecting table showing the overall configuration of the dissecting table ventilation system 1 of the present embodiment. As shown in this figure, the dissection table ventilation system 1 of this embodiment includes a dissection table 2 and a sock duct 5 installed in the longitudinal direction above the specimen mounting table 4 of the dissection table 2. .
解剖台２は、全体形状が、従来と同じく上部の開口した方形箱型の筐体３を備え、この筐体３内部に検体を載置する検体載置台４が設置されている。この筐体３は、例えば、四方に設けられた４本の脚ＬとキャスターＣとによって、移動可能に支持されている。 The dissection table 2 is provided with a rectangular box-shaped housing 3 having an open top as in the conventional case, and a sample mounting table 4 on which a sample is placed is installed inside the housing 3. The housing 3 is movably supported by, for example, four legs L and casters C provided in four directions.
また、解剖台２における筐体３の底面には、後述する排気チャンバ６に繋がる排気部７が設けられ、この排気部７は、排気チャンバ６への空気の通過量を調整する排気量調整シャッター７ａを備える。この排気量調整シャッター７ａは、例えば、方形に開口した排気口７ｂに対して、それと同大の板状体７ｃをスライド移動させ、排気口７ｂの開口量を変化させることで、排気量の調整を行なうものである。 Further, an exhaust part 7 connected to an exhaust chamber 6 described later is provided on the bottom surface of the housing 3 in the dissecting table 2, and the exhaust part 7 is an exhaust amount adjustment shutter that adjusts the amount of air passing into the exhaust chamber 6. 7a. The exhaust amount adjusting shutter 7a adjusts the exhaust amount by, for example, sliding the plate-like body 7c having the same size as the exhaust port 7b opened in a square shape and changing the opening amount of the exhaust port 7b. Is to do.
解剖台２において、検体載置台４と排気部７とは、２層構造となっており、図１に具体例を示すように、検体載置台４全体を盆状に形成し、検体載置部分４１と、この検体載置部分４１の四方に、解剖台２における筐体３の底面に隙間を設けるようにして、筐体３に対して検体載置部分４１を固定する載置台支持部４２とから構成する。また、図１（ｃ）に示すように、この載置台支持部４２には、筐体３底部の排気部７に通気するよう、排気孔４３が複数設けられている。 In the dissection table 2, the sample mounting table 4 and the exhaust unit 7 have a two-layer structure, and as shown in a specific example in FIG. 1, the entire sample mounting table 4 is formed in a tray shape, 41 and a mounting table support portion 42 for fixing the sample mounting portion 41 to the housing 3 so as to provide gaps on the bottom surface of the housing 3 of the dissecting table 2 on four sides of the sample mounting portion 41. Consists of. Further, as shown in FIG. 1C, the mounting table support portion 42 is provided with a plurality of exhaust holes 43 so as to ventilate the exhaust portion 7 at the bottom of the housing 3.
解剖台２の底部には、排気チャンバ６が取り付けられ、この排気チャンバ６は図示しない排ガス処理装置へ接続されている。すなわち、この排ガス処理装置により、吸気されることで、排気部７を通って排気チャンバ６内の空気が引かれ、さらに、排気孔４３を通して解剖台２の検体載置台４周囲の空気が引かれるように構成される。 An exhaust chamber 6 is attached to the bottom of the dissecting table 2, and the exhaust chamber 6 is connected to an exhaust gas treatment device (not shown). That is, when the exhaust gas is taken in by the exhaust gas processing apparatus, the air in the exhaust chamber 6 is drawn through the exhaust unit 7, and further, the air around the specimen mounting table 4 of the dissection table 2 is drawn through the exhaust hole 43. Configured as follows.
一方、図１（ａ）及び（ｂ）に示すように、解剖台２の上方には、断面が円形で、解剖台の長手方向に向かってソックスダクト５が設けられている。このソックスダクト５は、円筒形状を形成する布や孔開きシートから形成されるダクトで、布の網目やシートの細孔から空気が浸み出して微風速を形成するものである。 On the other hand, as shown in FIGS. 1 (a) and 1 (b), a sock duct 5 is provided above the dissecting table 2 so as to have a circular cross section and toward the longitudinal direction of the dissecting table. The sock duct 5 is a duct formed of a cloth or a perforated sheet forming a cylindrical shape, and air oozes out from the mesh of the cloth or the pores of the sheet to form a slight wind speed.
このような解剖台換気システム１では、ソックスダクト５の小孔から浸み出す微風速の空気により、解剖台２に向けて垂直落下方向に擬似層流Ｓを形成する。そして、このソックスダクト５からの擬似層流Ｓで解剖台２を包み、同時に解剖台２の検体載置台４において、検体を包み込みながらホルムアルデヒドを含んだ空気を、検体載置台４の周囲に設けられた排気孔４３に向けて排出する。排気孔４３に対しては、図示しない排ガス処理装置によって吸気されることで、排気部７を通って排気チャンバ６内の空気が引かれ、さらに、排気孔４３を通して解剖台２の検体載置台４周囲の空気が引かれ、上記のホルムアルデヒドを含んだ空気が、排気部７から排出される。 In such an anatomical table ventilation system 1, a pseudo laminar flow S is formed in the vertical drop direction toward the anatomical table 2 by air at a low wind speed that permeates from a small hole of the sock duct 5. Then, the anatomical table 2 is wrapped with the pseudo laminar flow S from the sock duct 5, and at the same time, in the sample mounting table 4 of the dissecting table 2, air containing formaldehyde is provided around the sample mounting table 4 while wrapping the sample. The air is discharged toward the exhaust hole 43. The exhaust hole 43 is inhaled by an exhaust gas processing device (not shown), whereby air in the exhaust chamber 6 is drawn through the exhaust unit 7, and further, the specimen mounting table 4 of the dissection table 2 is passed through the exhaust hole 43. Ambient air is drawn and the air containing formaldehyde is discharged from the exhaust section 7.
以上のような本実施形態の解剖台換気システム１では、解剖作業者が作業中に部分的に擬似層流Ｓを遮っても、解剖台の検体載置台周囲の排気孔４３からの排気があるため、検体から発生するホルムアルデヒドが解剖台２の外に拡散することがない。 In the dissection table ventilation system 1 of the present embodiment as described above, even if the dissection operator partially blocks the pseudo laminar flow S during the operation, there is exhaust from the exhaust holes 43 around the specimen mounting table of the dissection table. Therefore, formaldehyde generated from the specimen does not diffuse out of the dissecting table 2.
これにより、解剖実習室内及び解剖台端の解剖作業者の頭部近傍でのホルムアルデヒド濃度を規定値である０．１ｐｐｍ未満まで下げることができ、かつ作業性が良い解剖台換気システムを提供することが可能となる。 Accordingly, it is possible to reduce the formaldehyde concentration in the anatomy training room and in the vicinity of the head of the dissecting table at the dissecting table end to below the specified value of 0.1 ppm, and to provide a dissecting table ventilation system with good workability. It becomes possible.
［１−２．実施例］
［１−２−１．気流シミュレーションとフォグによる実験結果］
上記のような構成及び作用効果を奏する本実施形態の解剖台換気システム１について、気流シミュレーションを行った結果を以下に示す。まず、本気流シミュレーションは、図２（ａ）に示すように、長手方向に１１３００ｍｍ、短手方向に２２００ｍｍ、高さ方向に３０００ｍｍの長方形状の箱型の室Ｒを想定する。この仮想の室Ｒの上部に、長手方向に渡って、ソックスダクト５を設けるとともに、そのソックスダクト５に沿って、室Ｒ内の長手方向に渡って、本実施形態の解剖台換気システム１を３台縦列に並べたとする。
[1-2. Example]
[1-2-1. Experimental results by airflow simulation and fog]
The results of airflow simulation for the dissecting table ventilation system 1 of the present embodiment having the above-described configuration and operational effects are shown below. First, as shown in FIG. 2A, the air flow simulation assumes a rectangular box-shaped chamber R having a length of 11300 mm, a width of 2200 mm, and a height of 3000 mm. The sock duct 5 is provided in the upper part of the virtual room R in the longitudinal direction, and the dissecting table ventilation system 1 of the present embodiment is provided along the sock duct 5 in the longitudinal direction in the room R. Suppose that three units are arranged in a column.
このような領域モデルにおける気流シミュレーションの結果を図２（ｃ）〜（ｇ）として示す。なお、図２（ｃ）〜（ｇ）は、図２（ｂ）における断面（ｃ）〜（ｇ）を表したものであり、図中の矢印は、空気の流れを示すものである。 The results of the airflow simulation in such a region model are shown in FIGS. 2 (c) to 2 (g) show the cross sections (c) to (g) in FIG. 2 (b), and the arrows in the figure indicate the flow of air.
上記の気流シミュレーションによれば、図２（ｃ）〜（ｇ）に示すとおり、いずれの断面においても、ソックスダクト５からの擬似層流は渦を巻くことなく、また解剖台２から逆流することなく、解剖台２へ吸込まれ、解剖台２の排気口よりスムースに排気されていることが分かった。 According to the above airflow simulation, as shown in FIGS. 2C to 2G, the pseudo laminar flow from the sock duct 5 flows backward from the dissecting table 2 without any vortex in any cross section. It was found that the air was sucked into the dissecting table 2 and was smoothly exhausted from the exhaust port of the dissecting table 2.
また、本実施形態の解剖台２に対して、その周辺における気流を、フォグ（微細ミスト）で可視化した結果を図３に示す。この図３によれば、検体頭部直上における気流（図３（ａ））、解剖台２の外枠を構成する筐体３周辺の気流（図３（ｂ））、検体足下直上の気流（図３（ｃ））、解剖作業者の周辺の気流（図３（ｄ））のいずれの箇所においても、気流が解剖台２からその外へ逆流していないことを確認した。 Moreover, the result of having visualized the airflow in the periphery with respect to the dissecting table 2 of this embodiment by fog (fine mist) is shown in FIG. According to FIG. 3, the airflow just above the head of the specimen (FIG. 3A), the airflow around the casing 3 constituting the outer frame of the dissection table 2 (FIG. 3B), the airflow just above the specimen foot ( It was confirmed that the airflow did not flow backward from the dissecting table 2 to any part of the airflow around the dissection operator (FIG. 3C) and the airflow around the dissection operator (FIG. 3D).
［１−２−２．解剖台換気システムの実施例の概要と解剖実習室の実施例］
次に、本実施形態の解剖台換気システム１の実施例の概要と、解剖実習室ＰＲの平面図をそれぞれ図４及び図５に示す。空気調和機ＡＨＵ−１により外気ＯＡを温調して解剖実習室ＰＲヘソックスダクト５（図５の上から下に伸びた５本のソックスダクト５ａ〜５ｅ）から供給し、その分を床下取付吸込口Ｖ１（図５では図示せず）と吸気ガラリＶ２から排気用送風機ＥＦ−１により排気することで解剖実習室ＰＲ内を換気する。
[1-2-2. Outline of the example of the dissection table ventilation system and the example of the dissection laboratory]
Next, the outline | summary of the Example of the dissection table ventilation system 1 of this embodiment and the top view of the dissection training room PR are shown in FIG.4 and FIG.5, respectively. The outside air OA is temperature-controlled by the air conditioner AHU-1 and supplied from the dissection training room PR hexox duct 5 (five socks ducts 5a to 5e extending from the top to the bottom of FIG. 5), and the part is attached under the floor. The inside of the anatomy training room PR is ventilated by exhausting air from the suction port V1 (not shown in FIG. 5) and the intake gallery V2 by the exhaust fan EF-1.
同時に、給気用送風機ＳＦ−１により外気を解剖台２上方のソックスダクト５（図５の下から上に伸びた１０本のソックスダクト５ｆ〜５ｏ）から擬似層流として供給する。擬似層流として供給された空気は解剖台２の排気口からホルムアルデヒドと共に排気され、解剖台２から解剖実習室ＰＲ内へのホルムアルデヒドの拡散を防止する。ホルムアルデヒドを含んだ空気は、排ガス処理装置ＴＲＳ−Ｆ３００とＴＲＳ−Ｆ４００で処理された後、大気中に放出される。 At the same time, outside air is supplied as a pseudo laminar flow from the sock duct 5 above the dissecting table 2 (ten sock ducts 5f to 5o extending upward from the bottom of FIG. 5) by the air supply fan SF-1. The air supplied as the pseudo laminar flow is exhausted together with formaldehyde from the exhaust port of the dissecting table 2 to prevent the diffusion of formaldehyde from the dissecting table 2 into the dissection training room PR. The air containing formaldehyde is discharged into the atmosphere after being treated by the exhaust gas treatment apparatuses TRS-F300 and TRS-F400.
この実施例において、実際にホルムアルデヒド濃度を測定した測定点と結果をそれぞれ図５と図６に示す。図６のＡ測定点の値は、床上１２００ｍｍ（作業者の頭部を想定）におけるホルムアルデヒドの値を示している。Ｂ測定点の値は、解剖台２端上４００ｍｍ（作業者の頭部を想定）におけるホルムアルデヒドの濃度を示している。Ａ、Ｂ何れの値も規定値の０．１ｐｐｍ未満であることが分かる。なお、ホルムアルデヒド濃度の測定は、２，４−ＤＮＰＨ含浸シリカゲルで捕集して高速液体クロマトグラフ（島津製作所製 ＬＣ−１０ＡＤ）で行った。 In this example, the measurement points and results obtained by actually measuring the formaldehyde concentration are shown in FIGS. 5 and 6, respectively. The value of the measurement point A in FIG. 6 indicates the value of formaldehyde at 1200 mm (assuming the operator's head) on the floor. The value of the B measurement point indicates the concentration of formaldehyde at 400 mm (assuming the operator's head) on the end of the dissecting table 2. It can be seen that both values A and B are less than the specified value of 0.1 ppm. The formaldehyde concentration was measured with a high performance liquid chromatograph (LC-10AD manufactured by Shimadzu Corporation) after being collected with 2,4-DNPH impregnated silica gel.
このように、本実施形態の解剖台換気システム１を用いた実施例により、解剖実習室ＰＲ内及び解剖台端の解剖作業者の頭部近傍でのホルムアルデヒド濃度を規定値（０．１ｐｐｍ未満）まで下げることができることを確認した。 Thus, according to the example using the dissecting table ventilation system 1 of the present embodiment, the formaldehyde concentration in the dissection training room PR and in the vicinity of the dissecting operator's head at the dissecting table end to the specified value (less than 0.1 ppm). Confirmed that it can be lowered.
［２．他の実施形態］
本発明は、上記の実施形態に限定されるものではなく、以下のような態様も包含するものである。例えば、図７に示すように、解剖台の検体載置台周囲に、検体載置台の上方に向かってガス拡散防止板が設けることが可能である。より具体的には、このガス拡散防止板は、解剖台の周囲に、例えば、ビニール製の高さ２０ｃｍのガス拡散防止板を設けることにより実現する。これにより、検体からのホルムアルデヒドが解剖台の外に拡散することを効果的に防止することができるとともに、ガス拡散防止板は柔らかく簡単に変形可能に構成することで、解剖作業者の作業性を妨げることがない。
[2. Other Embodiments]
The present invention is not limited to the above embodiment, and includes the following aspects. For example, as shown in FIG. 7, a gas diffusion prevention plate can be provided around the specimen mounting table on the dissecting table toward the upper side of the sample mounting table. More specifically, this gas diffusion prevention plate is realized by providing, for example, a vinyl gas diffusion prevention plate having a height of 20 cm around the dissection table. This effectively prevents formaldehyde from the specimen from diffusing out of the dissection table, and the gas diffusion prevention plate is configured to be soft and easily deformable, thereby improving the workability of the dissection operator. There is no hindrance.
また、上記実施形態において、ソックスダクト５として断面円形のものを用いたが、本発明はこのような態様に限らず、解剖台上方で擬似層流が形成できるものであれば、例えば、図８に示すように断面が半円状のものを用いることも可能である。このような態様では、設置する解剖室のハード的制約に対応して、その解剖室にあった解剖台換気システムを提供することが可能となる。 Further, in the above embodiment, the sock duct 5 having a circular cross section is used. However, the present invention is not limited to such a mode, and any type of pseudo laminar flow can be formed above the dissection table, for example, FIG. It is also possible to use a semicircular cross section as shown in FIG. In such an aspect, it is possible to provide an anatomical table ventilation system suitable for the dissection room corresponding to the hardware restrictions of the dissection room to be installed.
