この考案は、防水構造にした防水型内視鏡の改
良に関する。[Detailed Description of the Invention] This invention relates to an improvement of a waterproof endoscope having a waterproof structure.
この種の内視鏡としては、内視鏡を液体の侵入
から守る密閉構造にして薬液消毒、つまり内視鏡
全体を薬液に浸漬したり、内視鏡を内視鏡内外を
連通させてガス滅菌、つまり内視鏡全体を滅菌容
器に入れてガス消毒したりするために採用されて
いる。 This type of endoscope has an airtight structure that protects the endoscope from liquid intrusion, and is sterilized with chemical solutions.In other words, the entire endoscope is immersed in a chemical solution, or the endoscope is connected inside and outside the endoscope to provide gas. It is used for sterilization, that is, for putting the entire endoscope in a sterile container and disinfecting it with gas.
ところで、この種の薬液消毒、ガス滅菌に供さ
れる内視鏡にあつては、特に薬液消毒における気
密不良によつて生じる内視鏡内部への薬液の侵入
が問題になるところである。 By the way, in the case of endoscopes subjected to this type of chemical disinfection and gas sterilization, intrusion of the chemical into the endoscope caused by poor airtightness during chemical disinfection is particularly problematic.
そこで、従来では、内視鏡のたとえば操作部に
圧力注入孔を設け、この圧力注入孔に防水検査用
検査具を接続して圧力注入孔を通じて内視鏡の内
部へ空気などを注入して内視鏡の防水が保たれて
いるか、否かを検知したり、あるいは通気性を有
すが通水性を有しない部材で内視鏡の一部を構成
して、ガス滅菌と薬液消毒とを別途操作を要する
ことなく行なうことができるようにした内視鏡な
どが開発されている。 Therefore, in the past, a pressure injection hole was provided in the operating section of the endoscope, a waterproof inspection tool was connected to this pressure injection hole, and air was injected into the endoscope through the pressure injection hole. It is possible to detect whether the endoscope is waterproof or not, or to configure part of the endoscope with a material that is breathable but not water permeable, and performs gas sterilization and chemical disinfection separately. Endoscopes and the like have been developed that allow this to be done without requiring any manipulation.
しかしながら、圧力注入孔を内視鏡に設けた構
造では、通常、圧力注入孔は開口しているため、
薬液消毒の際、別途コツクなどの開閉具でその圧
力注入孔をその都度切換閉塞する必要がある。と
ころで、圧力注入孔の閉塞操作は誤りやすく、薬

それが多大である。また、内視鏡の一部を通気性

ゴム被覆に亀裂を生じた場合などその気密不良が
わからず、薬液消毒に際して、この亀裂部分から
薬液が同様に侵入して内視鏡の破損をまねくとい
つた問題がある。 However, in a structure in which a pressure injection hole is provided in an endoscope, the pressure injection hole is usually open, so
When disinfecting with a chemical solution, it is necessary to switch and close the pressure injection hole each time using a separate opening/closing device such as a pot. By the way, it is easy to make mistakes in closing the pressure injection hole, and there is a great possibility that the chemical liquid will enter the inside of the endoscope and damage the optical equipment and other equipment when performing chemical disinfection. Furthermore, if a part of the endoscope is made of a material that has air permeability but not water permeability, there is no means for detecting whether waterproofness is maintained or not. For example, if there is a crack in the curved rubber coating of the insertion tube, the airtightness of the crack cannot be detected, and when disinfecting with a chemical solution, the chemical solution can similarly enter through the crack and cause damage to the endoscope.
この考案は上記事情に着目してなされたもの
で、その目的とするところは、内視鏡に内視鏡内
外を連通する連通口を設け、この連通孔に、防水

きるとともに、防水が保たれているか否かの検査
およびガス滅菌、薬液消毒を誤操作なく容易に、

なうことができるようにした防水型内視鏡を提供
しようとするものである。 This idea was devised by focusing on the above-mentioned circumstances, and its purpose is to provide a communication port in the endoscope that communicates the inside and outside of the endoscope, and to this communication hole, a test tool for waterproof testing can be connected. In addition, by providing a porous member that is not water permeable but has breathability and is encased when the waterproof test tool is connected, gas sterilization and chemical disinfection can be performed without any special operations. , inspection to see if waterproofness is maintained, gas sterilization, and chemical disinfection can be easily performed without any mistakes.
It is also an object of the present invention to provide a waterproof endoscope that can be used safely without liquid intrusion into the endoscope.
