[0061] figure 1 The shown endoscope cleaning and disinfection device (hereinafter simply referred to as device) 10 has a box-shaped device body 11 . The upper surface of the device main body 11 is provided with an endoscope 12 for accommodating use (refer to figure 2 ) of the cleaning tank 13. The cleaning tank 13 is a water tank with an open upper part, and is formed of a metal plate excellent in heat resistance, corrosion resistance, etc., such as stainless steel, for example.

[0062] A top cover 16 covering the upper portion of the cleaning tank 13 is provided on the upper portion of the apparatus main body 11 . The top cover 16 is, for example, a substantially rectangular plate-shaped body made of transparent plastic, and one side is pivotally supported by a hinge 17 provided on the upper surface of the device main body 11 so as to be freely openable and closable. A packing 16 a for sealing the inside of the cleaning tank 13 is provided on the inner periphery of the t...

[0147] Such as Figure 8 As shown, the replacement work of the disinfectant solution 97 takes a corresponding amount of time. When it is necessary to urgently clean and disinfect the endoscope 12 and the time for replacing the disinfectant solution 97 is reached, if the disinfectant solution is replaced, cleaning and disinfection followed by endoscopic examination will delay the time for disinfectant solution replacement. Therefore, a mechanism for additionally supplying the stock solution of the disinfectant solution 97 to the disinfectant solution tank 37 is provided, and cleaning and disinfection can be performed several times in an emergency without performing replacement work. In addition, components having the same structure and function as those of the above-mentioned embodiments are assigned the same reference numerals, and description thereof will be omitted.

[0148] exist Figure 10 Among them, the device 200 has a sub-tank 202 storing a stock solution 201 of the ...

Abstract

The invention provides a disinfection device. The disinfection liquid is recovered from a cleaning slot to a disinfection tank after the completion of the cleaning disinfection processing of the endoscope in the cleaning slot. After the recovery of the disinfection liquid, a concentration measurement control portion (157) measures the concentration of the disinfection liquid at the concentration sensor (132). The concentration measured by the concentration sensor (132) is inputted into a determination portion (158), and it is determined whether it is suitable for performing disinfection for the endoscope within the range of the concentration value. An input control portion (161) outputs the cleaning information including the determination result to each output target. The cleaning controlportion (155) removes the locking mechanism (23) of the top cover of the cleaning slot when the determination result is appropriate. When the determination result is not appropriate, the locking stateof the locking mechanism is maintained before the further disinfection of the endoscope by the novel disinfection liquid. In another embodiment, when the determination result is not appropriate, rawliquid is supplied to the disinfection liquid into the disinfection liquid tank.

Description

technical field [0001] The invention relates to a disinfection device for disinfecting used medical instruments. Background technique [0002] Endoscope washer-disinfectors for cleaning and disinfecting used endoscopes are widely known. The disinfectant solution used in the endoscope cleaning and disinfecting device is prepared by diluting a stock solution such as peracetic acid (also referred to as a concentrated solution) with a diluent such as water to a predetermined concentration (a concentration that can withstand repeated use). The disinfectant is stored in a disinfectant tank installed in the device, and a predetermined amount is supplied from the disinfectant tank to the cleaning tank in which the endoscope is accommodated during the disinfection process. In the disinfection process, the endoscope is soaked in a disinfectant solution to remove pathogenic bacteria or viruses, or eliminate their pathogenicity. [0003] Since the disinfectant is adjusted to a concent...
