Field of the Invention [0002] An endoscope cleaning apparatus for feeding a cleaning and disinfecting solution consisting of alkaline water and acidic water, and then cleaning with water. 2. Description of the Related Art In a conventional endoscope cleaning apparatus, it is almost ascertained that the disinfecting ability of disinfecting water composed of acidic water depends on the concentration of chlorine. However, conventionally, ph is measured. . However, in the conventional endoscope cleaning device, since the chlorine concentration of the cleaning water is not measured,
[0003] The endoscope cleaning apparatus attempts to visually check the disinfecting ability of the disinfecting water composed of acidic water in the endoscope cleaning apparatus during cleaning. [Technical Means] In a cleaning and disinfecting apparatus for disinfecting an apparatus for disinfecting alkaline water and acidic water from an electrolytic cell 1 through a supply pipe 2 to a cleaning pipe 3p of a cleaning device 3 and then cleaning with water. 2 Chlorine concentration detector 1 for acidic water
0 or the overflow plate 12
An endoscope cleaning device for detecting the chlorine concentration of acidic water in an overflow section 13 before passing through. [0005] The endoscope can be cleaned while confirming the disinfecting ability of the cleaning water composed of acidic water. Embodiments of the present invention will be described below. In FIGS. 1 and 2, 1: electrolysis tank 2: acidic water / alkaline water supply switching valve: acidic water / alkaline water switching valve 2a: acidic water pipe 2b: alkaline water pipe 2c: connection pipe 3: washing machine 3p : Cleaning pipe 4: Water pipe 5: Suction box 6: Connector 7: Endoscope v1: Sample amount adjustment valve v2: Sample storage valve 8a: Sample storage tank 8b: Sample storage chamber 8b: Sample 9: Diaphragm 10: Chlorine concentration Detector 11: Flexible cable. 12: Overflow plate 13: Overflow portion 14: Insertion hole of cable 11 connected to the overflow portion 15: Chlor test paper Hereinafter, the operation will be described. The acidic water and the alkaline water generated on the + side of the electrolytic cell 1 are supplied to the inside and outside of the flexible pipe 3p of the cleaning pipe 3p of the cleaning device 3 via the supply pipe 2. The disinfecting water reaches the overflow portion 13 through the insertion hole 14, overflows the overflow plate 12, and is drained from the drain pipe 13a. And finally, the water is washed from tap water.
Sent to Air is sucked from the suction box 5 inside the pipe 3p and dried. The water in the cleaning pipe 3p is drained by the drain pipe 3pa. a: First, the alkaline water is preliminarily washed through the alkaline water pipe 2b and the connection pipe 2c.
b: Next,
Switching between acidic water and pipe 2a for acidic water via valve v1
From the cleaning pipe 3 of the cleaning device 3 by the connecting pipe 2c.
p to wash the inside and outside of the flexible cable 11. Assuming that the diaphragm 9 is present, it is assumed that the following equilibrium relationship is established on the + side. Then, by measuring the chlorine concentration on the + side or the chlorine concentration in HCLO, it is possible to estimate the effect of the disinfecting water. This is because the chlorine concentration is considered to be proportional to the amount of hypochlorous acid generated.
Usually, quantitative detection of chlorine concentration by colorimetry is performed. The supply pipe 2 is provided with a switching valve 2v, and the acidic liquid is guided to the elemental concentration detecting device 10 and its chlorine concentration is detected. However, the detection of chlorine concentration is based on the fact that the acidic water passes through the passage hole 14 and overflows into the overflow plate 1.
It may be performed in the overflow portion 13 before exceeding 2. In FIG. 2, the acidic water flowing through the supply pipe 2 is introduced into the sample storage chamber 8 in the order of alkaline water, acidic water, and water through the switching valve 2v. . The concentration of the acidic water in the sample storage chamber 8 is detected by the chlor test paper 15. The acidic water in the storage chamber 8 is supplied to the sample storage valve v
2 is released and returned to the supply pipe 2. In order to prevent the alkaline water from impairing the disinfecting power of the acidic water, the alkaline water is washed off in advance. Alternatively, the cleaning may be performed in the overflow section 13 before the acidic water passes over the overflow pipe 12. Further, the detection of the chlorine concentration may not be performed by the colorimetric method using the chlor test paper described above. For example, it can be detected by the electrode method. c: Next, water is guided from the tap water to the washing pipe 3p for washing. d: Finally, air is sucked from the suction box 5 and the inside of the flexible cable 11 is dried.
