【発明の詳細な説明】
［発明の目的］
（産業上の利用分野）
本発明は、内視鏡のスコープ先端の端面に露出される対
物レンズ、ライトガイド等の光学系部材の端部を洗浄す
る内視鏡用洗浄液に関し、特に内視鏡検査時に適用され
る内視鏡用洗浄液に関する。Detailed Description of the Invention [Objective of the Invention] (Industrial Application Field) The present invention cleans the ends of optical system members such as objective lenses and light guides that are exposed at the end face of the tip of an endoscope. The present invention relates to a cleaning liquid for an endoscope, and particularly to a cleaning liquid for an endoscope that is applied during endoscopy.
（従来の技術）
従来、内？！鏡検査において、胃内の環境条件が過飽和
であるために、微妙な温度変化や圧力変化によって対物
レンズ表面が曇ってしまい観察の障害になっていた。(Conventional technology) Conventionally, within? ! During mirror examinations, because the environmental conditions within the stomach are supersaturated, the surface of the objective lens becomes cloudy due to subtle changes in temperature and pressure, impeding observation.
こうした対物レンズ表面の曇りを除く努力として、対物
レンズ表面に水を載せて対応する手技が知られており、
また内視鏡検査前にあらかじめ対物レンズ表面を浄化の
ため拭くなどするが、このとき用いるクリーナーとして
界面活性剤を含有したクリーナーを利用することもある
。In an effort to remove such cloudiness from the surface of the objective lens, a technique is known in which water is placed on the surface of the objective lens.
Furthermore, the surface of the objective lens is wiped for cleaning purposes before an endoscopy, and a cleaner containing a surfactant may be used as the cleaner used at this time.
（発明が解決しようとする課題）
しかしながら、対物レンズ表面に水を載せると、水の表
面張力が大きいので４水がレンズ状になってしまい、像
の歪みやボケを惹き起こす原因となって好ましくない。(Problem to be Solved by the Invention) However, when water is placed on the surface of the objective lens, the surface tension of the water is large, so the water becomes lens-shaped, causing distortion and blurring of the image. do not have.
更に、上記のクリーナーにおいては、現在、−般に高級
脂肪酸ナトリウム塩（化粧石けんの基剤）が用いられて
いるので、多聞には用いることができない。加えて観察
時には繰り返し対物レンズ表面を洗浄するために曇り止
めの効果が長つづきしないという不具合があった。Furthermore, in the above-mentioned cleaners, higher fatty acid sodium salts (bases of cosmetic soaps) are currently used, so they cannot be used extensively. In addition, the anti-fogging effect does not last long because the surface of the objective lens is repeatedly cleaned during observation.
本発明は、係る課題に鑑みてなされたもので、その目的
は、内視鏡検査時に、常に同じ条件で観察を行なうのに
好適な内視鏡用洗浄液を提供することにある。The present invention has been made in view of the above problems, and an object thereof is to provide an endoscope cleaning liquid suitable for always performing observation under the same conditions during endoscopic examination.
［発明の構成］
（ｉｌｌｌ！題を解決するための手段）本発明は、上記
の目的を達成するため、内視鏡洗浄液に、界面活性剤を
含有してなる内視鏡洗浄液を用いることを要旨としてい
る。[Structure of the Invention] (Means for Solving the Ill! Problem) In order to achieve the above object, the present invention provides the use of an endoscope cleaning liquid containing a surfactant. This is the summary.
（作用）
界面活性とは、周知のように存在する２相間のいずれか
に少憩の物質を溶解させることにより表面張力が大きく
低下する減少をいう。そして、一般に表面または界面に
吸着され、適当な親水基と親油基とを持った両親媒性物
質であれば界面活性剤として用いることができる。(Effect) As is well known, surface activity refers to a significant reduction in surface tension by dissolving a small amount of a substance between two existing phases. In general, any amphipathic substance that is adsorbed on a surface or interface and has appropriate hydrophilic and lipophilic groups can be used as a surfactant.
このような界面活性剤を含有してなる内視鏡洗浄液であ
れば、表面張力が小さいから、水を薄膜状に対物レンズ
面に載せる手技においては、像の歪みのない良好な画像
を与え、更に、過飽和内の観察においては温度、圧力の
微小な変化による曇りを減少させる防曇効果を奏する。An endoscope cleaning solution containing such a surfactant has a low surface tension, so it provides a good image without image distortion in a procedure in which a thin film of water is placed on the objective lens surface. Furthermore, when observing a supersaturated environment, it has an antifogging effect that reduces fogging caused by minute changes in temperature and pressure.
（実施例）
第１図は、界面活性剤を含有してなる本発明の内視鏡洗
浄液における表面張力と温度との関係を示している。(Example) FIG. 1 shows the relationship between surface tension and temperature in the endoscope cleaning liquid of the present invention containing a surfactant.
図に示される如く、表面張力の減少は、濃度の増加に対
し、最初の少鎖で極端に減少する傾向がある。As shown in the figure, the decrease in surface tension tends to decrease extremely in the first few chains as the concentration increases.
従って、第４図に示ず如くの内視鏡スコープ１の先端部
に露出されている対物レンズ２の表面に内視鏡用洗浄液
を一様に拡げる場合、少量の界面活性剤が混入された水
を内視鏡用洗浄液として用いれば良いことになる。なお

撮像素子３により、対物レンズ２を通した光を光電変換
して映像信号を得て、この映像信号を基に観察画像をモ
ニタ上に表示することができる。また、４は送水管であ
る。Therefore, when the endoscope cleaning liquid is uniformly spread over the surface of the objective lens 2 exposed at the tip of the endoscope 1 as shown in FIG. 4, a small amount of surfactant may be mixed in. This means that water can be used as a cleaning fluid for endoscopes. In Fig. 4, 3 is a solid-state image sensor, and the solid-state image sensor 3 photoelectrically converts the light passing through the objective lens 2 to obtain a video signal, and monitors an observed image based on this video signal. can be displayed on top. Further, 4 is a water pipe.
しかし、内視鏡検査は、被検体の体腔内で行なわれる理
由から、人体に無害でなければならないということにな
る。However, because endoscopy is performed inside the body cavity of the subject, it must be harmless to the human body.
そこで、第２図に、界面活性効果を示し、人体に無害な
物質の一例を示１゜
高級脂肪酸アルカリ塩（化粧石けん基剤）は、界面活性
効果が大きく、この点だけから見ると内視鏡用洗浄液に
含有される界面活性剤として有効である。その反面、Ｐ
Ｈが変化するなどの理由からその使用量が問題視される
。Therefore, Figure 2 shows an example of a substance that has a surfactant effect and is harmless to the human body.1゜Higher fatty acid alkali salts (toilet soap bases) have a large surfactant effect, and from this point alone, they have no internal effect. It is effective as a surfactant contained in mirror cleaning solutions. On the other hand, P
The amount used is viewed as a problem because H changes.
また、グリセリン、アミノ酸などは人体に無害であるが
、高級脂肪酸アルカリ塩に比べ界面活性効果が小さく、
内視鏡洗浄液に含有させても目標とする効果、即ち、表
面張力を大きく低下する現象を惹き起すのに不充分であ
る。In addition, although glycerin and amino acids are harmless to the human body, they have a smaller surfactant effect than higher fatty acid alkali salts.
Even if it is included in the endoscope cleaning solution, it is insufficient to bring about the desired effect, that is, the phenomenon of significantly lowering the surface tension.
そこで、本発明の実施の一例としては、第３図に示され
るような食品用乳化材のショ糖脂肪酸エステルを界面活
性剤として内視鏡用洗浄液に含有させた。Therefore, as an example of implementing the present invention, a sucrose fatty acid ester of a food emulsifier as shown in FIG. 3 was included as a surfactant in an endoscope cleaning liquid.
ショ糖脂肪酸エステルは、可食性で、目や皮膚に刺激性
が無く、優れた成分解性と安全性を持っている。更に、
界面活性効果は、他の界面活性材が水を１とした場合、
０．７〜０．８が一般であるのに対し、約０．５と非常
に優れており、内視鏡診断用の界面活性剤に適している
。Sucrose fatty acid ester is edible, non-irritating to the eyes and skin, and has excellent decomposition properties and safety. Furthermore,
The surfactant effect is when other surfactants are 1: water.
While 0.7 to 0.8 is common, it is about 0.5, which is very good and is suitable as a surfactant for endoscopic diagnosis.
この性質を利用して、ショ糖脂肪酸エステルの濃度を調
整し、内視鏡対物レンズ面（第４図参照）に薄膜を形成
し、曇り止め効果を得る条件設定を好適に行なえる。Utilizing this property, the concentration of sucrose fatty acid ester can be adjusted to form a thin film on the objective lens surface of the endoscope (see FIG. 4), and conditions can be suitably set to obtain the anti-fogging effect.
このようなことから、本発明の実施の一例によれば、内
視鏡検査時に、鮮明な画像を得るために対物レンズ面に
均一に水をのせる手技においては、像の歪みのない良好
な画像を与え、曇り防止の点において、内視鏡検査中に
劣化することのない良好な表面状態を与えることができ
た。Therefore, according to an embodiment of the present invention, in the technique of uniformly applying water on the objective lens surface in order to obtain a clear image during endoscopy, it is possible to obtain a good image without distortion. In terms of providing images and preventing fogging, it was possible to provide a good surface condition that does not deteriorate during endoscopy.
［発明の効果］
以上説明したように、本発明は、界面活性剤を含有して
