Description

【0001】
【技術分野】
本発明は、内視鏡または内視鏡処置具の洗浄方法及び装置に関する。
【0002】
【従来技術およびその問題点】
内視鏡や内視鏡処置具(以下、内視鏡等という)は、衛生管理上、使用後に必ず洗浄及び殺菌処理が施される。従来では、内視鏡等の外表面をスポンジ等で洗浄すると共に、内視鏡内部に設けられた各管路の内壁を洗浄ブラシでブラッシングしているが、このような洗浄方法では以下の課題が生じている。
【0003】
すなわち、近年では内視鏡内部の各管路が小径化されているため、洗浄ブラシの挿脱が容易ではなく、ブラッシング作業を簡単且つ短時間で行なうことができない課題がある。また、送気送水ノズルが送気送水管路に固定されたタイプの内視鏡では、送気送水管路の一端部側からしか洗浄ブラシを挿入することができず、洗浄できない部分が生じてしまう。さらに内視鏡等の外表面を洗浄する際には、汚れが残らないように隅々まで隈なく洗浄しなければならず、大変な労力を要している。
【0004】
【発明の目的】
本発明は、以上の問題意識に基づき、ブラシや洗浄具を用いることなく容易に洗浄できる内視鏡または内視鏡処置具の洗浄方法及び装置を得ることを目的とする。
【0005】
【発明の概要】
本発明による内視鏡または内視鏡処置具の洗浄方法は、内視鏡または内視鏡用処置具に対し、微細洗浄粒子を含む溶液を衝突させて洗浄することを特徴としている。
【0006】
このように微細洗浄粒子を用いれば、粒子レベルで汚れを除去することができ、内視鏡または内視鏡処置具及びその管路を隅々まで容易に洗浄することができる。よって、ブラシや洗浄具を用いて洗浄作業しなくて済み、内視鏡操作者の労力を減らすことができる。また微細洗浄粒子であれば、ノズル噴出口から該微細洗浄粒子によって落ちた汚れと共に排出できるので、固定式ノズルを備えた管路に対しても洗浄が可能となる。
【0007】
具体的な態様としては、微細洗浄粒子を含む溶液中に内視鏡または内視鏡処置具を浸漬しておき、該溶液を内視鏡または内視鏡処置具の管路に循環させて該内視鏡管路を洗浄することが好ましい。
【0008】
別の態様としては、微細洗浄粒子を含む溶液中に内視鏡または内視鏡処置具を浸漬しておき、該溶液を攪拌して洗浄することも可能である。この態様では、攪拌された溶液の液流により微細洗浄粒子が内視鏡または内視鏡処置具に衝突する。
【0009】
さらに別の態様としては、微細洗浄粒子を含む溶液を、内視鏡または内視鏡処置具に対してシャワー状の噴射液として与えることが好ましい。
【0010】
微細洗浄粒子は、シリカ、アルミナ、ハイドロキシアパタイト、活性炭、チタニア、銅粉、銀粉、二硫化モリブデンの一種以上からなることが好ましい。例えば、吸着性のあるハイドロキシアパタイトや活性炭が含まれていれば、汚れを吸着して内視鏡または内視鏡処置具から取り除くことができる。また、殺菌作用のある銅粉や銀粉が含まれていれば、洗浄と同時に殺菌を行なうことができる。また、光触媒であるチタニアが含まれていれば、光照射により汚れを分解することができる。
【0011】
微細洗浄粒子の粒径は、φ0.01mm以上φ0.5mm以下であることが好ましい。この範囲であれば、内視鏡管路が小径であっても隅々まで洗浄することができ、また固定式ノズルのノズル噴射口から外方へ流出することができる。なお、微細洗浄粒子の粒径は、上記範囲内でなくても、内視鏡管路径よりも小径であればよい。
【0012】
上記溶液は、水溶液とするのが実際的である。また上記溶液の溶媒としては、水以外にも、例えばグルタラルアルデヒドなどの消毒液を用いることが可能である。
【0013】
本発明による洗浄装置は、内視鏡または内視鏡処置具と、微細洗浄粒子を含む溶液とを入れる洗浄槽;この洗浄槽から上記溶液を汲み上げる吸引ポンプ;この吸引ポンプにより吸引された溶液を濾過する濾過装置;この濾過された溶液を、上記洗浄槽内に浸漬された内視鏡または内視鏡処置具の管路に流通させる送出ポンプ;を備えたことを特徴としている。この洗浄装置には、上記洗浄槽内の溶液を攪拌させて該溶液中の微細洗浄粒子を内視鏡または内視鏡処置具に衝突させる攪拌部材を備えることができる。
【0014】
本発明の洗浄装置は、別の態様では、内視鏡または内視鏡処置具と、微細洗浄粒子を含む溶液とを入れる洗浄槽;この洗浄槽から上記溶液を汲み上げる吸引ポンプ;この吸引ポンプにより吸引された溶液を濾過する濾過装置;この濾過された溶液を上記洗浄槽に戻す送出ポンプ;及び上記洗浄槽内の溶液を攪拌させて該溶液中の微細洗浄粒子を内視鏡または内視鏡処置具に衝突させる攪拌部材;備えたことを特徴としている。
【0015】
さらに別の態様では、内視鏡または内視鏡処置具を入れる洗浄槽;この洗浄槽内の内視鏡または内視鏡処置に対し、微細洗浄粒子を含む溶液をシャワー状に噴射する送出ポンプ;上記洗浄槽内に溜まった溶液を汲み上げる吸引ポンプ;及びこの吸引された溶液を濾過し、該濾過した液体を上記送出ポンプに供給する濾過装置;を備えたことを特徴としている。
【0016】
【発明の実施形態】
図1は、本発明の第1実施形態による洗浄装置10の全体構成を示している。洗浄装置10は、洗浄液11を入れた洗浄槽12と、洗浄槽12内の洗浄液11を吸引する吸引ポンプ13と、吸引ポンプ13が吸引した洗浄液11を濾過して汚れを取り除く濾過装置14と、濾過された洗浄液11を送出する送出ポンプ15とから構成されている。
【0017】
洗浄液11は、水を溶媒とする溶液であって、硬質の微細洗浄粒子11a(図2)を溶液中に含んでいる。微細洗浄粒子11aは、例えばシリカ、アルミナ、ハイドロキシアパタイト、活性炭、チタニア、銅粉、銀粉、二硫化モリブデンの一種以上であることが好ましい。この微細洗浄粒子11aの粒径は、内視鏡または内視鏡処置具の管路よりも小径であればよく、具体的には例えばφ0.01mm以上φ0.5mm以下程度とすることができる。
【0018】
第1実施形態の特徴は、図2に示すように洗浄液11を内視鏡管路21内に流通させ、洗浄液11中の微細洗浄粒子11aを汚れ30に衝突させることで、内視鏡管路21を洗浄する点にある。図1の矢印方向は、洗浄中に洗浄液11(微細洗浄粒子11a)が流れる方向を示している。
【0019】
洗浄装置10は、例えば内視鏡20を洗浄する場合、以下のように使用する。先ず、吸引チューブ16の一端部を吸引ポンプ13に接続して他端部を洗浄槽12内にセットし、内視鏡20の内視鏡管路21の各入口部21a〜21cと送出ポンプ15の送出口を送出チューブ17により接続する。次に、内視鏡20を洗浄槽12内にセットし、内視鏡20が完全に浸漬されるまで洗浄液11を洗浄槽12に入れる。そして吸引ポンプ13、濾過装置14及び送出ポンプ15を所定時間動作させ、内視鏡20を洗浄させる。
【0020】
吸引ポンプ13、濾過装置14及び送出ポンプ15の動作中は、吸引ポンプ13により洗浄液11が汲み上げられ、この洗浄液11が濾過装置14にて濾過された後、送出ポンプ15から内視鏡管路21の各入口部21a〜21cに所定の水圧で送出される。各入口部21a〜21cに供給された洗浄液11は内視鏡管路21を流れ、このとき微細洗浄粒子11aが管路内壁に付着した汚れ30に衝突することで該汚れ30が剥がれ落ち、内視鏡管路21が洗浄される。剥がれ落ちた汚れ30は、洗浄液11と共に内視鏡管路21の出口部21dから洗浄槽12に流出され、吸引ポンプ13により汲み上げられて濾過装置14に送られる。濾過装置14では汚れ30が取り除かれ、微細洗浄粒子11aを含む洗浄液11のみが送出ポンプ15から再度送出される。
【0021】
以上により、内視鏡管路21に付着した汚れ30が完全に除去されたら、内視鏡20を洗浄槽12から取り出して水洗いし、乾燥する。
【0022】
図3は、本発明の第2実施形態による洗浄装置50の全体構成を示している。第2実施形態は、洗浄槽12内にプロペラ(攪拌部材)18を設け、このプロペラ18により洗浄液11を攪拌させて内視鏡等を洗浄することを特徴としている。図3では、第1実施形態と実質的に同一機能を有する要素に図1と同一符号を付してある。
【0023】
洗浄装置50は、例えば内視鏡20を洗浄する場合、次のように使用する。先ず、洗浄槽12と吸引ポンプ13を吸引チューブ16により接続し、送出チューブ17の一端部を送出ポンプ15に接続して他端部を洗浄槽12内にセットする。次に、内視鏡20を洗浄槽12にセットし、内視鏡20が完全に浸漬されるまで洗浄液11を洗浄槽12に入れる。そして吸引ポンプ13、濾過装置14、送出ポンプ15及びプロペラ18を所定時間動作させ、内視鏡20を洗浄させる。
【0024】
プロペラ18が回転すると、該回転により洗浄液11が攪拌され、洗浄液11の液流により微細洗浄粒子11aが洗浄槽12内を移動する。この移動中、微細洗浄粒子11aが内視鏡20に衝突すると、内視鏡20の外表面に付着した汚れが微細洗浄粒子11aにより落とされ、内視鏡20の外表面が洗浄される。洗浄液11は、吸引ポンプ13により上記汚れと共に汲み上げられ、濾過装置14で汚れ30が取り除かれた後、送出ポンプ15から洗浄槽12内に再度送出される。
【0025】
以上により、内視鏡20の外表面に付着した汚れが完全に除去されたら、内視鏡20を洗浄槽12から取り出して水洗いし、乾燥する。
【0026】
図4は、本発明の第3実施形態による洗浄装置60の全体構成を示している。第3実施形態は、送出ポンプ15に接続する送出チューブ17の先端部に複数の噴射口19aを有するシャワーヘッド19を設け、各噴射口19aから洗浄液11を噴射して内視鏡等を洗浄することを特徴としている。図4では、第1実施形態と実質的に同一機能を有する要素に図1と同一符号を付してある。
【0027】
洗浄装置60は、例えば内視鏡20を洗浄する場合、以下のように使用する。先ず、洗浄槽12と吸引ポンプ13を吸引チューブ16により接続し、送出チューブ17の後端部を送出ポンプ15に接続する。次に、内視鏡20を洗浄槽12内にセットし、洗浄液11を洗浄槽12内に適量入れる。そして吸引ポンプ13、濾過装置14及び送出ポンプ15を動作させ、内視鏡20の洗浄を開始させる。
【0028】
吸引ポンプ13、濾過装置14及び送出ポンプ15の動作中は、洗浄液11が吸引ポンプ13、濾過装置14、送出ポンプ15及び送出チューブ17を介してシャワーヘッド19に供給され、シャワーヘッド19の各噴射口19aから所定の水圧で内視鏡20に向かって噴射される。この噴射力により洗浄液11中の微細洗浄粒子11aは、図5に示すように内視鏡20に当て付けられ、この衝突により汚れ30を内視鏡20の外表面から落としていく。洗浄液11(微細洗浄粒子11a)は、吸引ポンプ13により上記汚れ30と共に汲み上げられ、濾過装置14で汚れ30が取り除かれた後、送出ポンプ15から再度送出される。以上により、内視鏡20の外表面に付着した汚れ30が完全に除去されたら、内視鏡20を洗浄槽12から取り出して水洗いし、乾燥する。
【0029】
以上のように各実施形態では、洗浄液11中の微細洗浄粒子11aを衝突させることで、内視鏡管路21の内壁または内視鏡20の外表面に付着した汚れを物理的に落としている。この微細洗浄粒子11aによれば、内視鏡20及び内視鏡管路21を隅々まで容易に洗浄することができ、ブラシやスポンジ等の洗浄具を用いずに済む。また微細洗浄粒子11aであれば、ノズル噴射口から汚れと共に排出できるため、固定式ノズルを備えた内視鏡管路に対しても洗浄可能となる。
【0030】
上記各実施形態では、内視鏡20を洗浄する場合について説明したが、内視鏡用処置具を洗浄する場合についても同様である。
【0031】
また上記各実施形態では、洗浄液11の溶媒として水を用いているが、該溶媒は水に限定されず、例えばグルタラルアルデヒド等の消毒液や弱度の洗浄液を用いることも可能である。また洗浄液11中に含まれる微細洗浄粒子としては、衝突時に内視鏡外表面や内視鏡管路が傷つけないように、より軟性の粒子を選択してもよい。
【0032】
以上、図示実施形態を参照して本発明を説明したが、本発明の洗浄装置は図示実施形態に限定されず、種々の変形が可能である。例えば、第1実施形態における洗浄装置(図1)にも洗浄液を攪拌させる攪拌部材を設ければ、内視鏡外表面と内視鏡管路の洗浄を同時に行なうことが可能となる。
【0033】
【発明の効果】
本発明によれば、内視鏡または内視鏡処置具をブラシや洗浄具を用いることなく容易に洗浄することができる。

The arrow direction in FIG. 1 indicates the direction in which the cleaning liquid 11 (fine cleaning particles 11a) flows during cleaning.
[0019]
The cleaning device 10 is used as follows, for example, when cleaning the endoscope 20. First, one end of the suction tube 16 is connected to the suction pump 13, and the other end is set in the washing tank 12, and each of the inlets 21 a to 21 c of the endoscope channel 21 of the endoscope 20 and the delivery pump 15. Are connected by a delivery tube 17. Next, the endoscope 20 is set in the cleaning tank 12, and the cleaning liquid 11 is put into the cleaning tank 12 until the endoscope 20 is completely immersed. Then, the suction pump 13, the filtering device 14, and the delivery pump 15 are operated for a predetermined time to clean the endoscope 20.
[0020]
During operation of the suction pump 13, the filtration device 14 and the delivery pump 15, the cleaning liquid 11 is pumped up by the suction pump 13, and after the cleaning solution 11 is filtered by the filtration device 14, the endoscope conduit 21 is sent from the delivery pump 15. Is sent out at a predetermined water pressure to each of the inlet portions 21a to 21c. The cleaning liquid 11 supplied to each of the inlets 21a to 21c flows through the endoscope conduit 21. At this time, the fine cleaning particles 11a collide with the dirt 30 attached to the inner wall of the conduit, and the dirt 30 is peeled off. The endoscope channel 21 is cleaned. The peeled dirt 30 flows out together with the cleaning liquid 11 from the outlet 21 d of the endoscope channel 21 to the cleaning tank 12, is pumped up by the suction pump 13, and is sent to the filtration device 14. The dirt 30 is removed in the filtration device 14, and only the cleaning liquid 11 containing the fine cleaning particles 11 a is sent out again from the sending pump 15.

During this movement, when the fine cleaning particles 11a collide with the endoscope 20, dirt attached to the outer surface of the endoscope 20 is removed by the fine cleaning particles 11a, and the outer surface of the endoscope 20 is cleaned. The cleaning liquid 11 is pumped together with the dirt by the suction pump 13, and after the dirt 30 is removed by the filtering device 14, the cleaning liquid 11 is sent out again from the sending pump 15 into the washing tank 12.
[0025]
As described above, when the dirt attached to the outer surface of the endoscope 20 is completely removed, the endoscope 20 is taken out of the cleaning tank 12, washed with water, and dried.
[0026]
FIG. 4 shows the overall configuration of a cleaning device 60 according to a third embodiment of the present invention. In the third embodiment, a shower head 19 having a plurality of injection ports 19a is provided at a distal end portion of a delivery tube 17 connected to a delivery pump 15, and the endoscope and the like are washed by ejecting the cleaning liquid 11 from each of the ejection ports 19a. It is characterized by: In FIG. 4, elements having substantially the same functions as in the first embodiment are denoted by the same reference numerals as in FIG.
[0027]

The water is sprayed from the mouth 19a toward the endoscope 20 at a predetermined water pressure. The fine cleaning particles 11a in the cleaning liquid 11 are applied to the endoscope 20 as shown in FIG. 5 by the spraying force, and the collision causes the dirt 30 to fall off the outer surface of the endoscope 20. The cleaning liquid 11 (fine cleaning particles 11 a) is pumped up together with the dirt 30 by the suction pump 13, and after the dirt 30 is removed by the filtering device 14, the cleaning liquid 11 is sent out again from the sending pump 15. As described above, when the dirt 30 attached to the outer surface of the endoscope 20 is completely removed, the endoscope 20 is taken out of the cleaning tank 12, washed with water, and dried.
[0029]
As described above, in each embodiment, the dirt attached to the inner wall of the endoscope channel 21 or the outer surface of the endoscope 20 is physically removed by colliding the fine cleaning particles 11a in the cleaning liquid 11. . According to the fine cleaning particles 11a, the endoscope 20 and the endoscope channel 21 can be easily cleaned to all corners, without using a cleaning tool such as a brush or a sponge. In addition, since the fine cleaning particles 11a can be discharged together with dirt from the nozzle injection port, it is possible to clean even an endoscope channel having a fixed nozzle.
[0030]
In the above embodiments, the case where the endoscope 20 is cleaned has been described. However, the same applies to the case where the endoscope treatment tool is cleaned.
[0031]
In each of the above embodiments, water is used as the solvent of the cleaning liquid 11, but the solvent is not limited to water. For example, a disinfecting liquid such as glutaralaldehyde or a weak cleaning liquid can be used. As the fine cleaning particles contained in the cleaning liquid 11, softer particles may be selected so as not to damage the outer surface of the endoscope or the endoscope channel at the time of collision.
[0032]
As described above, the present invention has been described with reference to the illustrated embodiments. However, the cleaning device of the present invention is not limited to the illustrated embodiments, and various modifications are possible. For example, if the cleaning device (FIG. 1) of the first embodiment is also provided with a stirring member for stirring the cleaning liquid, it is possible to simultaneously clean the outer surface of the endoscope and the endoscope conduit.
[0033]
【The invention's effect】
According to the present invention, an endoscope or an endoscope treatment tool can be easily cleaned without using a brush or a cleaning tool.
