Description

本考案は、皮膚ガスや呼気ガスをオンラインにて迅速に測定する装置であり、皮膚ガスの測定感度を向上させた装置である。さらに詳しくは一酸化窒素測定用の環境空気導入に際しての効果的な乾燥剤配列を有する皮膚ガスや呼気ガスを用いたセンシング装置に関するものである。         The present invention is an apparatus for quickly measuring skin gas and exhaled gas online, and is an apparatus with improved skin gas measurement sensitivity. More specifically, the present invention relates to a sensing device using skin gas or exhalation gas having an effective desiccant array when introducing ambient air for measuring nitric oxide.

従来、皮膚ガスや呼気ガス中の微量成分をその場測定するためには、皮膚ガスや呼気ガスを採取して、濃縮して次いで簡易ガスクロマトグラフにより測定することが実施されている。
この時、室内外環境空気中に存在する永久ガス気体分子以外の水分子や大気汚染物質を吸着させるための吸着剤としてシリカゲル(特許文献1)などで行われている。また、アンモニア吸着剤としてもシリカゲル(特許文献2)が利用されている。
さらには、成分を吸着させる固相は、成分の特性に応じて適切なものを選択するものであるが、例えば、2,6-ジフェニル-p-フェニレンオキサイド樹脂などの多孔性樹脂、活性炭やカーボンモレキュラーシーブ等の多孔性炭素、グラファイトカーボンブラック等の非多孔性炭素、モレキュラーシーブ等のゼオライト、アルミナ、シリカゲル(特許文献3)等が挙げられ、利用されている。
これら文献にはシリカゲルへの水分などの吸着後の再利用に際しての考慮がされておらず日常的にメンテナンスすることの開示は示されていない。また一酸化窒素ガスの測定における大気汚染物質の除去にモレキュラシーブが有効であることが開示されていない。
皮膚ガスの多センサーを用いたセンシング装置(特許文献4)においても、室内空気を装置内に導入して測定を実施している。この際に正常化された空気を用いることが要求されている。
Conventionally, in order to measure trace components in skin gas and exhaled gas in situ, it has been practiced to collect skin gas and exhaled gas, concentrate and then measure by simple gas chromatograph.
At this time, silica gel (Patent Document 1) or the like is used as an adsorbent for adsorbing water molecules other than permanent gas molecules present in indoor and outdoor environment air and air pollutants. Silica gel (Patent Document 2) is also used as an ammonia adsorbent.
Furthermore, as the solid phase for adsorbing the components, an appropriate one is selected according to the characteristics of the components. For example, porous resins such as 2,6-diphenyl-p-phenylene oxide resin, activated carbon and carbon Porous carbon such as molecular sieve, non-porous carbon such as graphite carbon black, zeolite such as molecular sieve, alumina, silica gel (Patent Document 3) and the like are used.
These documents do not give consideration to the reuse after adsorption of moisture or the like on silica gel, and do not disclose the routine maintenance. Further, it is not disclosed that molecular sieve is effective for removing air pollutants in measurement of nitric oxide gas.
Even in a sensing device using a multi-sensor of skin gas (Patent Document 4), measurement is performed by introducing room air into the device. At this time, it is required to use normalized air.

ヒト皮膚ガスや呼気ガス中に含まれる化学成分を簡便に検出し、迅速にその場での健康状態をその場で表示できる装置に用い、該装置の測定感度および精度を高めるばかりでなく、日常的な吸着剤の脱着を容易にした皮膚ガスや呼気ガスを用いたセンシング装置を提供するものである。             It is used in a device that can easily detect chemical components contained in human skin gas and exhaled gas and quickly display the health status on the spot. It is an object of the present invention to provide a sensing device using skin gas or exhaled gas that facilitates desorption of a typical adsorbent.

本考案は、皮膚ガスや呼気ガス中の一酸化窒素を簡便に検出するための迅速測定装置への環境空気を導入に際しての乾燥管配列に関するものであり、水分や低級炭化水素などの吸着後の乾燥管の日常的交換を容易にしたものであり、ガスセル中の発光測定に良好に清浄化された環境空気を提供する。         The present invention relates to a drying tube arrangement for introducing environmental air into a rapid measurement device for simply detecting nitric oxide in skin gas and exhaled gas, and after adsorption of moisture, lower hydrocarbons, etc. It facilitates routine replacement of the drying tube and provides well-cleaned ambient air for luminescence measurements in gas cells.

以上説明から明らかなように本考案は、シリカゲル乾燥管の日常的な交換により常に乾燥ガスが得られるようになり、またシリカゲル乾燥管で取り切れなかったプロパン、ブタン等の低分子ガスをモレキュラーシープにより除去することができ、一酸化窒素発光を安定化することができる。     As can be seen from the above description, the present invention makes it possible to always obtain dry gas by routine replacement of the silica gel drying tube, and low molecular gases such as propane and butane that could not be removed by the silica gel drying tube. Therefore, the emission of nitric oxide can be stabilized.

本考案は特許文献4に開示されている皮膚ガスを試料とし多センサーを用いて迅速にセンシング装置に適用したところ非常に安定したベースが得られ高い測定感度が得られる。
In the present invention, when skin gas disclosed in Patent Document 4 is used as a sample and is quickly applied to a sensing device using multiple sensors, a very stable base can be obtained and high measurement sensitivity can be obtained.

以下、本考案の実施の形態を図に基づいて説明する。     Hereinafter, embodiments of the present invention will be described with reference to the drawings.

実施例を図面に従って説明すると、図1は、皮膚ガスを用いたセンシング装置の一例を示す構成図であり、第2図は、乾燥管の配列を示す実施例である。         An embodiment will be described with reference to the drawings. FIG. 1 is a configuration diagram showing an example of a sensing device using skin gas, and FIG. 2 is an embodiment showing an arrangement of drying tubes.

A skin gas sampling unit 26, an ozone generation unit 28, a gas cell unit 29 for obtaining light emission by ozone reaction of nitrogen monoxide in the skin gas, and a photomultiplier tube 30 for measuring light emission. .

実施例をより詳しく説明すると図2のイとロの組み合わせがある。乾燥剤を充填した乾燥管の配列は、交換用シリカゲルからなる交換部21と22、常時用シリカゲルからなる常時部23、さらに後方にモレキュラーシープを充填した乾燥管24からなる乾燥剤列から構成されている。交換用シリカゲル乾燥管は、単数イと複数ロのいずれかを用いることができる。         The embodiment will be described in more detail. The arrangement of the drying tubes filled with the desiccant is made up of a desiccant column composed of replacement parts 21 and 22 made of silica gel for replacement, a constant part 23 made of silica gel for regular use, and a drying tube 24 filled with molecular sheep behind. ing. As the silica gel drying tube for replacement, either single or double rods can be used.

乾燥管交換部21と22は容易に取り換え可能であり、予備の未吸着交換部と簡単に交換するとともに、常時部23の乾燥にも寄与するものである。さらにモレキュラーシープの乾燥部24は、交換部21と22および常時部23で取り切れなかったプロパンやブタン等の低分子ガスを吸着除去し、一酸化窒素発光を安定化するのに寄与している。
複数のシリカゲル充填乾燥管の使用は、シリカゲルの乾燥剤としての能力を示すコバルトを添加した青色のシリカゲルを使用すると交換のインジケーターをして有効であり、日常の管理に優れている。
The drying tube replacement sections 21 and 22 can be easily replaced, and can be easily replaced with a spare unadsorbed replacement section and contribute to the drying of the constant section 23. Further, the molecular sheep drying section 24 adsorbs and removes low-molecular gases such as propane and butane that cannot be removed by the exchange sections 21 and 22 and the constant section 23, and contributes to stabilizing nitric oxide emission. .
The use of a plurality of silica gel-filled drying tubes is effective as a replacement indicator when blue silica gel added with cobalt, which shows the ability of silica gel as a desiccant, is effective in daily management.
