Description

この発明は内視鏡の水漏れ検査装置に関する。   The present invention relates to an endoscope water leak inspection apparatus.

内視鏡は、内部に水分が浸入するいわゆる水漏れが発生すると、観察、照明、湾曲等各部の機能が劣化して総分解修理を余儀なくされる場合が多く、内部の湿度が高い状態になっただけでも、各内蔵物どうしの間に塗布してある潤滑粉が湿って滑りが悪くなることにより、屈曲時に光学繊維束やチューブ類等のような内蔵物が破損する原因になる場合がある。   Endoscopes are often in a state where the internal humidity is high due to the deterioration of the functions of each part, such as observation, illumination, and bending, when the so-called water leaks that cause moisture to enter the endoscope. However, the lubrication powder applied between the built-in components may become damp and slip, which may cause damage to built-in components such as optical fiber bundles and tubes when bent. .

そこで従来は、内視鏡の内部と外部との間を連通させる通気口金に送気ポンプを接続して内視鏡の内部を陽圧にし、内視鏡の外壁部にピンホール等があればそこから空気が漏れ出して内部の圧力が下がるので、その圧力降下を検出することで水漏れ検出をおこなっていた（例えば、特許文献１）。また、内視鏡内の高湿化防止のためには、通気口金部分に乾燥剤を配置していた（例えば、特許文献２）。
特開２００１−２４５８３９ 特開２００４−７３２５８ Therefore, conventionally, if an air supply pump is connected to a vent hole that communicates between the inside and outside of the endoscope to make the inside of the endoscope positive pressure, and there is a pinhole or the like on the outer wall of the endoscope Since air leaks from there and the internal pressure drops, water leakage is detected by detecting the pressure drop (for example, Patent Document 1). Further, in order to prevent high humidity in the endoscope, a desiccant has been disposed in the vent metal part (for example, Patent Document 2).
JP 2001-245839 A JP 2004-73258 A

しかし、内視鏡の内部を陽圧にして内視鏡内部から外部への空気の漏れ出しを検出する検査方法では、内視鏡の外部から内部に水が浸入する水漏れとは流れの方向が逆なので、ピンホールの位置や形状等によっては必ずしも水漏れ発生の有無を正しく検出することができない。また、乾燥剤による高湿化防止方法では、乾燥剤がある程度以上水分を吸収してしまうと乾燥機能が低下したり無くなったりするので、持続性に乏しい。   However, in the inspection method that detects the leakage of air from the inside of the endoscope to the outside with positive pressure inside the endoscope, the water leak that enters the inside from the outside of the endoscope is the direction of flow Therefore, depending on the position and shape of the pinhole, it is not always possible to correctly detect the presence or absence of water leakage. In addition, in the method for preventing high humidity using a desiccant, if the desiccant absorbs moisture more than a certain amount, the drying function is reduced or lost, and therefore the sustainability is poor.

そこで本発明は、水漏れ発生の有無を正しく検出することができる内視鏡の水漏れ検査装置を提供することを目的とし、さらに、内視鏡内の空気を確実に乾燥させることもできる内視鏡の水漏れ検査装置を提供することを目的とする。   Therefore, an object of the present invention is to provide an endoscope water leak inspection apparatus capable of correctly detecting the presence or absence of occurrence of water leak, and further, it is possible to reliably dry the air in the endoscope. An object of the present invention is to provide a water leakage inspection apparatus for an endoscope.

上記の目的を達成するため、本発明の内視鏡の水漏れ検査装置は、外部との間が隔壁により気密に仕切られた内視鏡の内部と外部との間を連通させるように内視鏡に設けられた通気口金に着脱自在に接続される内視鏡の水漏れ検査装置であって、内視鏡の内部から空気を吸引して内視鏡の内部を負圧にするための吸引ポンプと、吸引ポンプにより負圧にされた後の内視鏡内の気圧の変動を検出するための圧力計とを備えたものである。   In order to achieve the above object, the endoscope water leakage inspection apparatus according to the present invention is configured so that the inside and the outside of the endoscope that are hermetically partitioned from each other by a partition wall are communicated with each other. Endoscope water leakage inspection device that is detachably connected to a vent hole provided in a mirror, and sucks air from the inside of the endoscope to create a negative pressure inside the endoscope A pump and a pressure gauge for detecting a change in atmospheric pressure in the endoscope after being made negative by the suction pump are provided.

なお、内視鏡の通気口金との接続部に、外気との間を封止するためのシール部材が設けられているとよく、内視鏡の内部が負圧になってその気圧の変動を圧力計が検出する状態のときに内視鏡の内部と吸引ポンプとの間を封止するための閉鎖弁が設けられていれば、微細なピンホールからの漏れも検出することができる。   It should be noted that a seal member for sealing between the outside air and the connection portion of the endoscope with the vent hole base is preferably provided, and the inside of the endoscope becomes a negative pressure and the fluctuation of the atmospheric pressure is reduced. If a closing valve is provided for sealing between the inside of the endoscope and the suction pump when the pressure gauge detects, leakage from a fine pinhole can also be detected.

そして、吸引ポンプと並列に送気ポンプが設けられると共に、吸引ポンプと送気ポンプのうちいずれか一方だけを選択して内視鏡の内部に連通させるように切り換え自在な切り換え弁が設けられていてもよく、その場合に、送気ポンプにより内視鏡の内部に送り込まれる空気を除湿するための除湿装置が設けられていれば、内視鏡の内部の空気を乾燥した空気と入れ換えて確実に乾燥させることができる。   In addition, an air supply pump is provided in parallel with the suction pump, and a switchable switching valve is provided so that only one of the suction pump and the air supply pump can be selected and communicated with the inside of the endoscope. In that case, if a dehumidifying device is provided to dehumidify the air sent into the endoscope by the air supply pump, the air inside the endoscope is replaced with dry air to ensure Can be dried.

本発明によれば、内視鏡の内部から空気を吸引して内視鏡の内部を負圧にするための吸引ポンプと、吸引ポンプにより負圧にされた後の内視鏡内の気圧の変動を検出するための圧力計とを備えることにより、内視鏡の外部から内部への漏れ動作に基づいて水漏れ発生の有無を正しく検出することができ、さらに、送気ポンプにより内視鏡の内部に送り込まれる空気を除湿するための除湿装置を設ければ、内視鏡内の空気を確実に乾燥させることができる。   According to the present invention, the suction pump for sucking air from the inside of the endoscope to make the inside of the endoscope have a negative pressure, and the pressure of the air pressure in the endoscope after being made negative by the suction pump By providing a pressure gauge for detecting fluctuations, it is possible to correctly detect the presence or absence of water leakage based on the leakage operation from the outside to the inside of the endoscope. If the dehumidifying device for dehumidifying the air sent into the inside of the endoscope is provided, the air in the endoscope can be reliably dried.

外部との間が隔壁により気密に仕切られた内視鏡の内部と外部との間を連通させるように内視鏡に設けられた通気口金に着脱自在に接続される内視鏡の水漏れ検査装置であって、内視鏡の内部から空気を吸引して内視鏡の内部を負圧にするための吸引ポンプと、吸引ポンプにより負圧にされた後の内視鏡内の気圧の変動を検出するための圧力計とを備えている。   Endoscope water leakage inspection that is detachably connected to a vent hole provided in the endoscope so that the inside and outside of the endoscope that is hermetically partitioned by a partition wall are communicated with each other.

図面を参照して本発明の実施例を説明する。
図２において１０は内視鏡であり、可撓性挿入部１１の先端付近には遠隔操作により屈曲する湾曲部１１ａが形成され、可撓性挿入部１１の基端に連結された操作部１２から後方に延出する連結可撓管１３の先端には、図示されていないビデオプロセッサに接続されるコネクタ部１４が連結されている。 Embodiments of the present invention will be described with reference to the drawings.
In FIG. 2, reference numeral 10 denotes an endoscope. A bending portion 11 a that is bent by remote operation is formed in the vicinity of the distal end of the flexible insertion portion 11, and the operation portion 12 connected to the proximal end of the flexible insertion portion 11. A connector portion 14 connected to a video processor (not shown) is connected to the distal end of the connecting flexible tube 13 extending rearward from the terminal.

このように構成された内視鏡１０は、内部では全体が一つながりに連通していて、外部との間が隔壁により全て気密に仕切られて水や空気が外部から内視鏡１０内に浸入しないように構成されている。そして、コネクタ部１４には、内視鏡１０の内部と外部との間を連通させるための通気口金１５が設けられている。   The endoscope 10 configured in this way is connected in a continuous manner as a whole inside, and the outside is all hermetically partitioned by a partition wall so that water and air enter the endoscope 10 from the outside. It is configured not to. The connector portion 14 is provided with a vent hole 15 for communicating between the inside and the outside of the endoscope 10.

通気口金１５は例えば特許文献２に記載されているように公知のものであり、通気口金１５の内部には、外部と内部との間を閉塞する可動栓１６がコイルスプリング１７により内方から外方に向かって付勢されて配置されており、コイルスプリング１７の付勢力に抗して可動栓１６を押し込んで内方に退避させれば、内視鏡１０の内外が連通する状態になる。   The vent 15 is known as described in, for example, Patent Document 2, and a movable plug 16 that closes between the outside and the inside is provided from the inside by a coil spring 17 inside the vent 15. If the movable stopper 16 is pushed against the urging force of the coil spring 17 and retracted inward, the inside and outside of the endoscope 10 are in communication with each other.

１は本発明の内視鏡の水漏れ検査装置であり、水漏れ検査装置１から延出する連通管２の先端に取り付けられた接続口金３を通気口金１５に接続することにより、可動栓１６が内方に退避されて連通管２が内視鏡１０内と連通する状態になり、接続口金３を通気口金１５から取り外せば再び通気口金１５が閉じた状態になる。   Reference numeral 1 denotes an endoscope water leak inspection apparatus according to the present invention. A movable cap 16 is connected to a vent base 15 by connecting a connection base 3 attached to the tip of a communication pipe 2 extending from the water leak inspection apparatus 1. Is retracted inward and the communication tube 2 communicates with the endoscope 10, and when the connection base 3 is removed from the vent base 15, the vent base 15 is closed again.

図１は、そのような接続口金３が通気口金１５に取り付けられた状態を示しており、接続口金３に形成されたカム溝３ａを、通気口金１５から側方に突出して設けられた係合ピン１８に係合させることにより、接続口金３が通気口金１５に取り付けられた状態が維持される。そして、接続口金３の内面部分に設けられたＯリング状のシール部材３ｂにより、外気と連通管２内及び内視鏡１０内との間が封止される。   FIG. 1 shows a state in which such a connection base 3 is attached to the vent base 15, and the cam groove 3 a formed in the connection base 3 is provided to protrude from the vent base 15 to the side. By engaging with the pin 18, the state in which the connection base 3 is attached to the vent base 15 is maintained. The space between the outside air and the inside of the communication pipe 2 and the endoscope 10 is sealed by an O-ring-shaped seal member 3 b provided on the inner surface portion of the connection base 3.

水漏れ検査装置１内には、吸引ポンプ４と送気ポンプ５が並列に配置されていて、吸引ポンプ４の吸気口と送気ポンプ５の送気口とが三方切り換え弁６を介して連通管２と接続されている。   A suction pump 4 and an air supply pump 5 are arranged in parallel in the water leak inspection apparatus 1, and the intake port of the suction pump 4 and the air supply port of the air supply pump 5 communicate with each other via a three-way switching valve 6. Connected to the tube 2.

したがって、三方切り換え弁６を切り換えることにより、吸引ポンプ４と送気ポンプ５のいずれか一方又は双方が連通管２に接続された状態、及びどちらも連通管２に接続されない状態を任意に選択することができる。   Therefore, by switching the three-way switching valve 6, a state where one or both of the suction pump 4 and the air supply pump 5 are connected to the communication pipe 2 and a state where neither of them is connected to the communication pipe 2 is arbitrarily selected. be able to.

また、三方切り換え弁６と連通管２との間には連通管２に対して常時連通する位置に圧力計７が配置され、送気ポンプ５の空気取り入れ口側には除湿装置８が接続されている。除湿装置８は、例えば空調用の冷凍サイクルを用いた装置を用いることができ、除湿装置８を通って除湿された空気が送気ポンプ５によって送り出される。   A pressure gauge 7 is disposed between the three-way switching valve 6 and the communication pipe 2 at a position that always communicates with the communication pipe 2, and a dehumidifier 8 is connected to the air intake side of the air supply pump 5. ing. As the dehumidifying device 8, for example, a device using a refrigeration cycle for air conditioning can be used, and air dehumidified through the dehumidifying device 8 is sent out by the air supply pump 5.

このように構成された実施例の内視鏡の水漏れ検査装置１により内視鏡１０の水漏れ検査を行う場合には、図３に黒三角で示されるように、三方切り換え弁６を送気ポンプ５に対して閉塞して、連通管２に対して吸引ポンプ４だけが連通する状態に切り換え、吸引ポンプ４を動作させる。   When the endoscope water leak inspection apparatus 1 of the embodiment configured as described above performs the water leak inspection of the endoscope 10, the three-way switching valve 6 is sent as shown by a black triangle in FIG. The suction pump 4 is operated by closing the air pump 5 and switching to a state where only the suction pump 4 communicates with the communication pipe 2.

すると、連通管２と接続口金３とを経由して内視鏡１０内の空気が吸引排出されて、内視鏡１０内が外部に対して負圧になる。その結果、内視鏡１０の隔壁のどこかに孔があいていれば、圧力計７に表示される内視鏡１０内の圧力が低下しないので、水漏れが発生する状態であることを検出することができる。   Then, the air in the endoscope 10 is sucked and discharged through the communication pipe 2 and the connection base 3, and the inside of the endoscope 10 becomes a negative pressure with respect to the outside. As a result, if there is a hole somewhere in the partition wall of the endoscope 10, the pressure in the endoscope 10 displayed on the pressure gauge 7 does not decrease, so it is detected that water leaks. can do.

内視鏡１０の隔壁に微細ではあるが水漏れの原因になるようなピンホールがある場合には、吸引ポンプ４の運転に伴って、圧力計７に表示される内視鏡１０内の圧力が次第に低下する。   When the partition wall of the endoscope 10 has a pinhole that is fine but causes water leakage, the pressure in the endoscope 10 displayed on the pressure gauge 7 as the suction pump 4 is operated. Gradually decreases.

その場合、図４に黒三角で示されるように、連通管２に対し吸引ポンプ４と送気ポンプ５のどちらもが接続されていない状態に三方切り換え弁６を切り換えて、連通管２が三方切り換え弁６（閉鎖弁）で塞がれた状態にすれば、その後、圧力計７に表示される内視鏡１０内の圧力が徐々に上昇するので、微細なピンホールの存在でも検出することができる。   In that case, as shown by a black triangle in FIG. 4, the three-way switching valve 6 is switched to a state where neither the suction pump 4 nor the air supply pump 5 is connected to the communication pipe 2, so that the communication pipe 2 is three-way. If the switch valve 6 (closed valve) is closed, then the pressure in the endoscope 10 displayed on the pressure gauge 7 gradually increases, so that even the presence of fine pinholes can be detected. Can do.

このようにして、本発明によれば内視鏡１０の外部から内部への漏れ動作に基づいて水漏れ検査を行うことができる。そして、水漏れが発生しない状態であることが確認されたら、図５に黒三角で示されるように、三方切り換え弁６（切り換え弁）を、吸引ポンプ４に対し閉塞して、連通管２に対して送気ポンプ５だけが連通する状態に切り換え、送気ポンプ５と除湿装置８を動作させる。   Thus, according to the present invention, it is possible to perform a water leak inspection based on the leakage operation from the outside to the inside of the endoscope 10. When it is confirmed that no water leakage occurs, the three-way switching valve 6 (switching valve) is closed with respect to the suction pump 4 as shown by a black triangle in FIG. On the other hand, the air supply pump 5 and the dehumidifier 8 are operated by switching to the state where only the air supply pump 5 is in communication.

そのようにすることによって、除湿装置８で除湿された空気が連通管２と接続口金３を経由して内視鏡１０内に充填され、内視鏡１０内を外部と同じ圧力に戻すことができるだけでなく、内視鏡１０内の空気を乾燥した空気と入れ換えることができる。   By doing so, the air dehumidified by the dehumidifying device 8 is filled into the endoscope 10 via the communication pipe 2 and the connection base 3, and the inside of the endoscope 10 is returned to the same pressure as the outside. Not only can the air in the endoscope 10 be replaced with dry air.

その際に、内視鏡１０内が外部より高圧の状態になるまで送気をすれば、特許文献１に記載されているような従来の水漏れ検査方法も実施することができ、その場合には、最後に図１に示されるように連通管２に対して吸引ポンプ４と送気ポンプ５の双方が連通する状態に三方切り換え弁６を切り換えて、吸引ポンプ４も送気ポンプ５も停止させれば、内視鏡１０内が外部と同じ圧力に戻る。   At that time, if air is supplied until the inside of the endoscope 10 is in a state of high pressure from the outside, a conventional water leak inspection method as described in Patent Document 1 can also be performed. Finally, as shown in FIG. 1, the three-way switching valve 6 is switched to a state where both the suction pump 4 and the air supply pump 5 communicate with the communication pipe 2, and the suction pump 4 and the air supply pump 5 are stopped. Then, the inside of the endoscope 10 returns to the same pressure as the outside.
