【従来技術】従来の自動内視鏡洗浄消毒方法の多くは、
消毒装置内にグルタールアルデハイド系の薬剤使用する
ため、この中に所定時間内視鏡を浸潰させた後に水道水

されたとは考えにくい。2. Description of the Related Art Many of the conventional automatic endoscope cleaning and disinfecting methods include:
In order to use glutar aldehyde-based chemicals in the disinfection device, the endoscope is immersed in this for a predetermined time and then washed with tap water. Remains and it is unlikely that it has been completely washed away.
【０００３】グルタールアルデハイドの人体に対する毒
性を考えた場合、内視鏡の消毒は完全であっても完全に
安全とは思われない。[0003] Considering the toxicity of glutaraldehyde to the human body, disinfection of an endoscope is not completely safe even if it is complete.
【０００４】また、内視鏡の洗浄消毒を行なう従事者は
臭気により、気分が悪くなったり、グルタールアルデハ
イドに対するアレルギーにより気管支炎や皮膚炎を起こ
す場合がある。[0004] In addition, a worker who cleans and disinfects an endoscope may feel bad due to odor, or may cause bronchitis or dermatitis due to allergy to glutaraldehyde.
【０００５】さらに、使用済みのグルタールアルデハイ

が及ぶと考えられる。[0005] Furthermore, if used glutar aldehyde is allowed to flow from a drain, it is considered that the toxicity affects the natural environment.
【０００６】数年前から強酸性水の消毒力が注目されて
おり、医療施設や食品を扱う施設で多く使用され始めた
が、強酸性水は有機物と接触すると急激に消毒力を失う
といった欠点がある。The disinfecting power of strongly acidic water has been attracting attention for several years, and it has begun to be widely used in medical facilities and facilities handling food. However, strong acid water rapidly loses its disinfecting power when it comes into contact with organic substances. There is.
【０００７】しかし、強酸性水は人体毒性も無くわずか
に塩素臭を伴うが、アレルギーの治療などにも使用さ
れ、消毒効果が優れ安全でかつ自然環境の破壊を伴わな
い。[0007] However, although strongly acidic water has no human toxicity and has a slight chlorine odor, it is also used for treatment of allergies, etc., and has an excellent disinfecting effect, is safe and does not involve destruction of the natural environment.

いもので、操作部の洗浄消毒までを考慮した機種はグル
タールアルデハイドを使用する数機種に限られている。[0008] Recently, an endoscope cleaning and disinfecting apparatus using strongly acidic water has been put on the market. However, this is a cleaning and disinfecting apparatus that re-filters and regenerates the strongly acidic water used for cleaning and disinfecting the endoscope. However, only the washing and disinfection of the intubation part of the endoscope to the patient can be performed, and only a few models that use glutar aldehyde are limited to the washing and disinfection of the operation unit.

という欠点が解決されておらず、内視鏡洗浄消毒装置と
しては、一抹の不安が残るし、内視鏡の操作部分までを
含めた洗浄消毒は考慮されていない限り、患者への二次
感染の可能性を否定できない。However, this does not solve the disadvantage that the disinfecting effect is lost due to the incorporation of organic substances, particularly mucus and blood, which are characteristic of strongly acidic water. Unless cleaning and disinfection including the operation part of the endoscope is considered, the possibility of secondary infection to the patient cannot be ruled out.

The strong alkaline water overflows the overflow section 7 to clean the cable assembly 9. Drainage is through the communication hole 8 in the overflow section 7
Drained from At this time, the upper end of the cable 9b is set slightly lower than the upper end of the overflow plate 4.

予め、送水口金９ｄ、通気管９ｈを洗浄しておく。In the process of cleaning and disinfecting the first alkaline water, the suction cap 9c of the endoscope is connected to the suction forceps port cleaning device 11 as shown in FIGS. 6 and 7, and the suction passage 9b and the U of the forceps insertion port 9f are connected. Washing with alkaline water stored in the pipe washing pipe 3a is performed. When the cleaning of the gas supply pipe 9g is completed, the endoscope is pulled up from the alkaline water U-shaped pipe cleaning pipe 3a within 30 seconds. At this time, the water supply mouthpiece 9d and the ventilation pipe 9h are cleaned in advance by the gas supply / liquid supply port cleaning device 10.

Are a suction box 11a, a vacuum pump 11b, a backflow prevention tube 11c, a suction base 9c, a vinyl tube 11
During the operation of the vacuum pump 11b, the backflow prevention tube 11c is operated, and the cleaning liquid flows into the suction box 11a from the suction base 9c. When the operation of the vacuum pump 11a is completed, the vinyl tube 1 is pulled from the suction base 9c.
1d, or when the vacuum pump 11b is turned off, the backflow prevention tube 1 is pressed by the water pressure in the suction box 11a.
The backflow prevention action of 1b is automatically released and drained.

る。[Development of Overflow Type Endoscope Cleaning / Disinfecting Apparatus Using Strongly Acidic Water] Next, the development process of the present invention will be described. Strong acid water is characterized by a strong disinfecting effect and if it is drained after use, it is returned to nature as water. In addition, the safety of the human body is high, and the endoscope can be completely and completely disinfected safely and in a short time by recognizing only the disadvantages of strong acid water.

である。According to the present invention, an endoscope cleaning / disinfecting apparatus which eliminates the disadvantage that the disinfecting effect rapidly disappears when strongly acidic water comes into contact with mucus, blood, or the like is created, and the disinfecting effect is improved.

置ＥＷ−２０をセットした場合の奥行きに相当する。The endoscope cleaning / disinfecting apparatus of the present invention employs an overflow system so that the endoscope being disinfected always comes in contact with fresh strongly acidic water. In order to make the size of the device as compact as possible in the United States, a curve is provided along the flexibility of the endoscope,
The height was set to 950 mm to adapt the entire size to the length of the colonoscope, and 800 mm for the medium length. The depth is 730 mm, which is equivalent to the depth when the Olympus automatic cleaning device EW-20 is set.

Further, in order to avoid the metal corrosive action due to the oxidation of the strongly acidic water, the apparatus uses a vinyl chloride plate and a vinyl chloride pipe and does not use any metals.

約６〜７分であった。Practical washing: After the endoscope examination, the washing is performed by brushing the suction forceps port and easily washing out mucus and the like adhering around the endoscope. Next, it was set in an endoscope washer (EW-2) manufactured by Olympus Corporation, and washed with running water for 3 minutes as shown in FIG. , 30 seconds of strong acidic water and 30 seconds of tap water were used as washing standards. As a result, the time from the start of cleaning of the endoscope to the wiping was about 6 to 7 minutes even when the cleaning time with EW-2 was added for 3 minutes.

The culture test materials are liquid at the end of endoscopy, EW-2
The liquid 3 minutes after washing with water and the three materials after washing with the washing device developed by us were respectively performed on 33 cases.

養結果As a result, it was determined that the disinfecting effect of the strongly acidic water was insufficient and that it could not be used for disinfection after endoscopic examination. Since the disinfecting effect of the strongly acidic water greatly depends on the chlorine concentration, the concentration was increased to a pH of 2.5 and the chlorine concentration was increased to 50 ppm, and the bacteria were further cultured in 30 cases after washing.

なくとも挿入部、操作部までの消毒が必要と考える。In order to use strongly acidic water for cleaning and disinfecting an endoscope, the pH must be 2.5 or less, and the chlorine concentration must be 50 ppm or more.
It may be necessary to wash with as much strong acid water as possible. In addition, in order to cover the weakness of strongly acidic water, which is said to be ineffective due to contact with organic substances such as mucus and blood, there is a question about the disinfecting effect in the case of washing and disinfecting with stored water, but that overflows In this method, the endoscope is always in contact with fresh strongly acidic water. It is desirable to clean and disinfect the endoscope by disinfecting the entire endoscope, but it is necessary to disinfect at least the insertion section and the operation section.
