no. 1 approach

[0018] Next, an example of the embodiment of the present invention will be described. figure 1 The endoscope washer-disinfector 1 shown is a device for regenerating an endoscope. The regeneration treatment mentioned here is not particularly limited, and may be rinsing treatment with water, cleaning treatment to wash away dirt such as organic matter, disinfection treatment to inactivate specified microorganisms, sterilization treatment to remove or kill all microorganisms, and these treatments any of the combinations.

[0019] In addition, in the following description, an upper part means a position farther from the ground than a comparison object, and a lower part means a position closer to the ground than a comparison object. In addition, height in the following description shows the height relationship along the gravity direction.

[0020] The endoscope washer-disinfector 1 includes a control unit 5 , a power supply unit 6 , a treatment tank 2 , a tank 20 , a density mete...

[0115] Next, a second embodiment of the present invention will be described. Hereinafter, only the points of difference from the first embodiment will be described, and the same reference numerals will be assigned to the same components as those in the first embodiment, and descriptions thereof will be appropriately omitted.

[0116] Figure 5 It is a figure showing the structure of the endoscope washer-disinfector 1 of this embodiment. In this embodiment, the structure of the second adjustment unit 92 for adjusting the pressure Po of the liquid to be measured 100 stored in the tank 20 is different from that of the first embodiment.

[0117] Such as Figure 5 As shown, the pump 92 a of the second adjustment unit 92 in this embodiment also serves as the air pump 35 . The pump 92a is connected to the vent hole 20c of the tank 20 via the suction line 92b. A release valve 92c as a solenoid valve is provided on the suction line 92b. The release valve 92c releases the inside of...

no. 3 approach

[0122] Next, a third embodiment of the present invention will be described. Hereinafter, only differences from the first embodiment and the second embodiment will be described, and the same reference numerals will be assigned to the same constituent elements as those in the first embodiment and the second embodiment, and descriptions thereof will be appropriately omitted.

[0123] Image 6 It is a figure showing the structure of the endoscope washer-disinfector 1 of this embodiment. This embodiment differs from the first and second embodiments in that the tank 20 in which the densitometer 80 is arranged and the measurement target liquid recovery unit 29 are provided as separate containers.

[0124] The amount of the measurement object liquid 100 stored in the measurement object liquid recovery unit 29 is larger than the minimum amount of the measurement object liquid 100 required for the endoscope washer-disinfector 1 to execute the regeneration process. The measurement targ...

Abstract

An endoscope reprocessor of the present invention includes: a concentration meter including a housing including a hollow, an osmosis membrane covering the hollow, and internal liquid stored in the hollow; a tank configured to store measurement target liquid and holding the concentration meter so that the osmosis membrane is in contact with the measurement target liquid; a first adjusting portion configured to adjust a pressure of the internal liquid; a second adjusting portion configured to adjust a pressure of the measurement target liquid; a controlling portion configured to control the first adjusting portion and the second adjusting portion to enter a first state in which the pressure of the internal liquid is a first pressure, and the pressure of the measurement target liquid is a second pressure, and a second state in which the pressure of the internal liquid is a third pressure lower than the first pressure, and the pressure of the measurement target liquid is a fourth pressure lower than the second pressure; and a maintaining portion configured to maintain the second state for a predetermined time period.

Description

technical field [0001] The present invention relates to an endoscope washer-disinfector equipped with a densitometer using a permeable membrane. Background technique [0002] Endoscopes used in the medical field are regenerated using chemical solutions such as cleaning and disinfection after use. In addition, there is known an endoscope washer-disinfector that automatically regenerates an endoscope. For example, Japanese Patent Application Laid-Open No. 2010-57792 discloses an endoscope washer-disinfector equipped with a densitometer for measuring the concentration of a liquid to be measured, which is a chemical liquid used in regeneration processing. [0003] As a densitometer, there is known a densitometer using a permeable membrane through which a specific substance in a liquid to be measured permeates. When measuring the concentration of the liquid to be measured using the densitometer of this type, the liquid to be measured is brought into contact with the measurement...
