においては感染を防ぐ意味からも、上記外表面および各
種管路を倉入りに洗浄する必要がある。Not only the outer surface of a used endoscope, but also various conduits such as air and water supply, suction, and forceps insertion channels are contaminated with dirt and mucus inside the body cavity, so there is a risk of infection after use. In order to prevent this, it is necessary to thoroughly clean the above-mentioned external surfaces and the various pipe lines.
この内視鏡の管路を洗浄する器具としては、従来、例え
ば「特開昭５８−１５８３６号公報」に示されるように
、内視鏡の操作部に設けたシリンダに専用の接続口体を
接続し、この接続口体から管路内に洗浄液を供給するも
の、あるいは「特開昭５９−１８３７２４号公報」に示
されるように、各管路にシリンジを用いて洗浄液を圧送
するものが知られている。Conventionally, as a device for cleaning the conduit of an endoscope, a dedicated connection port is attached to a cylinder provided in the operating section of the endoscope, as shown in, for example, ``Japanese Unexamined Patent Publication No. 15836/1983.'' There are known methods that connect the pipes and supply the cleaning liquid into the pipes from this connection port body, or that use a syringe to pump the washing liquid into each pipe line as shown in ``Japanese Patent Application Laid-open No. 183724/1981. It is being
ところが、内視鏡の各管路は小径で、しかも複雑に折れ
曲がっていたり、内径が部分的に変化する等して、段差
が形成されていることが多いので、この管路内に洗浄液
を単に流すだけの従来の洗浄器具では、管路内面に付告
した汚物類を簡単に洗い流すことが困難であった。However, each conduit in an endoscope has a small diameter, and is often complicatedly bent, or the inner diameter changes partially, resulting in steps. With conventional cleaning equipment that only flushes, it is difficult to easily wash away dirt deposited on the inner surface of the pipe.
したがって、洗浄液を管路内に幾度となく繰り返し流さ
なければ、充分な洗浄効果が得られず、洗浄時間に長時
間を要して、洗浄作業に手間を要するとともに、洗浄液
も多量に消費する等の問題があった。Therefore, a sufficient cleaning effect cannot be obtained unless the cleaning liquid is repeatedly flowed into the pipe, which requires a long time for cleaning, which requires time and effort for cleaning, and a large amount of cleaning liquid is consumed. There was a problem.
本発明はこのような事情にもとづいてなされたもので、
複雑に入り組んだ管路内を、短時間のうちに簡単かつ確
実に洗浄することができる内視鏡の洗浄器具の提供を目
的とする。The present invention was made based on these circumstances, and
To provide an endoscope cleaning instrument that can easily and reliably clean the inside of a complicated duct within a short time.

口を設けたことを特徴とする。Therefore, the cleaning device according to the present invention includes a gas-liquid two-phase foaming fluid made by mixing a cleaning liquid and carbon dioxide gas, and supplies jets of this foaming fluid to various pipes of an endoscope. It is characterized by having a mouth.
この構成によれば、洗浄液は二酸化炭素ガスとの混合に
より、気液二相の発泡性流体となって供給口から管路内
に流入するが、この際、発泡性流体は二酸化炭素ガスが
圧力の低下によって一度に気化する際の勢いにより、高
速な噴流となって管路内に流れ込む。したがって、管路
の内面は高速な噴流に直接さらされることになり、この
管路の内面に付着した汚物類の除去が容易に行なわれる
。According to this configuration, the cleaning liquid becomes a gas-liquid two-phase foaming fluid by mixing with carbon dioxide gas and flows into the pipe line from the supply port, but at this time, the foaming fluid has carbon dioxide gas under pressure Due to the force of vaporization at once due to the drop in water, it becomes a high-speed jet and flows into the pipe. Therefore, the inner surface of the pipe is directly exposed to the high-speed jet stream, and dirt adhering to the inner surface of the pipe can be easily removed.
しかも、管路中を発泡性流体が流れる過程においては、
この発泡性流体中に含まれる多数の気泡が破裂を繰り返
し、この破裂時の衝撃波が管路内面に伝わるので、この
衝撃によっても上記汚物類の除去効果が高められること
になり、この除去された汚物類は高速な噴流に乗じて一
気に管路外に排出される。Moreover, in the process of the foaming fluid flowing through the pipe,
A large number of bubbles contained in this foaming fluid burst repeatedly, and the shock wave at the time of bursting is transmitted to the inner surface of the pipe, so this shock also enhances the removal effect of the above-mentioned filth. The filth is taken advantage of by the high-speed jet stream and is discharged out of the pipe all at once.
したがって、管路の内面には、高速の噴流が接すること
による洗浄効果と、気泡が破裂する際の衝撃による洗浄
効果とが相乗的に作用することになり、従来に比べて迅
速かつ確実に洗浄することができる。Therefore, the cleaning effect of the high-speed jet coming into contact with the inner surface of the pipe and the cleaning effect of the impact when the bubbles burst work synergistically, resulting in faster and more reliable cleaning than before. can do.
