Problems solved by technology

[0004] However, when hot water or diluted chemical solution is transferred through pipelines or filter devices in the endoscope cleaning and disinfection device, sometimes the temperature of the pipeline or filter device is lower than the temperature of hot water or diluted chemical solution, resulting in hot water Or the temperature of the diluted liquid drops
In addition, the temperature of hot water or diluted chemical solution may drop due to the influence of the liquid remaining in the pipeline or filter device at a temperature lower than that of hot water or diluted chemical solution.
[0005] When the temperature of hot water or diluted chemical solution drops, it is necessary to reheat the hot water or diluted chemical solution to the specified temperature range with a heater, resulting in waiting time and the time required for cleaning or disinfection of the endoscope. extend

no. 1 Embodiment approach

[0019] Hereinafter, a first embodiment of the present invention will be described. figure 1 It is a figure explaining the schematic structure of the endoscope cleaning and disinfection apparatus of 1st Embodiment. figure 2 It is a flowchart illustrating the schematic operation of the endoscope cleaning and disinfecting apparatus according to the first embodiment. image 3 is a flowchart of the diluted chemical solution generation process.

[0020] The endoscope cleaning and disinfection device 1 of the present embodiment has a cleaning tank 2, a dilution tank 3, a liquid medicine storage unit 7, a control unit 8, a plurality of pipelines, valves, etc. which will be described in detail later. Roughly speaking, the endoscope cleaning and disinfecting apparatus 1 is a device that dilutes the medicine stored in the medicine solution storage unit 7 in the dilution tank 3 with hot water supplied from a hot water supply source 9 provided outside the apparatus. solution to generate...

no. 2 Embodiment approach

[0062] Next, a second embodiment of the present invention will be described. Figure 4 It is a figure explaining the schematic structure of the endoscope cleaning and disinfection apparatus of 2nd Embodiment.

[0063] The second embodiment differs from the first embodiment in the manner in which the diluted chemical solution is transferred from the dilution tank 3 to the cleaning tank 2 . Hereinafter, only the points of difference from the first embodiment will be described, and the same reference numerals will be assigned to the same constituent elements as those in the first embodiment, and descriptions thereof will be appropriately omitted.

[0064] In this embodiment, the fourth pipeline 40 connected to the dilution tank 3 and the cleaning tank 2 is arranged, and the first pump 21 is arranged on the fourth pipeline 40 . Therefore, in the disinfection process in step S5 , by operating the first pump 21 , the diluted chemical solution stored in the dilution tank 3 is transf...

no. 3 Embodiment approach

[0066] Next, a third embodiment of the present invention will be described. Figure 5 It is a figure explaining the schematic structure of the endoscope cleaning and disinfection apparatus of 3rd Embodiment.

[0067] The third embodiment differs from the first embodiment in the manner in which the diluted chemical solution is transferred from the dilution tank 3 to the cleaning tank 2 . Hereinafter, only the points of difference from the first embodiment will be described, and the same reference numerals will be assigned to the same constituent elements as those in the first embodiment, and descriptions thereof will be appropriately omitted.

[0068] In this embodiment, a fifth pipeline 50 connected to the bottom surface of the cleaning tank 2 and the dilution tank 3 and a sixth pipeline 51 branched from the fifth pipeline 50 and connected to the second pipeline 20 are arranged. . A fourth valve 54 is disposed on the cleaning tank 2 side of the branch point of the fifth line 5...

Abstract

The invention provides a device and method for cleaning and disinfecting an endoscope. The endoscope in a cleaning tank is treated with a dilute liquid chemical obtained by diluting a liquid chemical with warm water in a dilution tank. The device is characterized in that: the warm water is introduced into the cleaning tank just before the treatment; after the temperature of the warm water being introduced into the cleaning tank becomes in a specified range, the warm water is introduced into the dilution tank to yield the dilute liquid chemical; and the dilute liquid chemical is introduced into the cleaning tank to treat an endoscope.

Description

technical field [0001] The present invention relates to an endoscope cleaning and disinfection device and an endoscope cleaning and disinfection method for sterilizing an endoscope using a diluted chemical solution diluted with hot water controlled so that the water temperature falls within a predetermined range. Background technique [0002] As an apparatus for cleaning and disinfecting an endoscope used in the medical field using a chemical solution, an endoscope cleaning and disinfecting apparatus disclosed in JP 2000-126125 A is known. [0003] Among the chemical solutions for cleaning or disinfection of endoscopes, some are preferably used within a predetermined temperature range higher than room temperature. For example, in the endoscope cleaning and disinfection apparatus described in JP 2000-126125 A, a diluted chemical solution obtained by diluting the chemical solution with hot water supplied from a hot water supply source such as a hot water supply facility can be...
