Problems solved by technology

In this case, the collision ratio of the droplet to the larger dirt is larger than that of the smaller droplet, so it has the effect of being able to remove the larger dirt in a short time, but as the droplet becomes larger, the gas The flow velocity of the liquid two-phase flow, especially the flow velocity near the pipe wall is slower than the gas flow velocity, so there is a problem that the biofilm attached to the pipe wall cannot be removed

no. 1 Embodiment approach

[0036] figure 1 It is a perspective view showing the cleaning and disinfecting device of this embodiment, figure 2 It is a perspective view of the washer-disinfector showing a state in which the top cover is opened and the endoscope is freely accommodated in the washer-disinfector tank.

[0037]As shown in the figure, the cleaning and disinfecting device 1 is a device for cleaning and disinfecting a used endoscope 100. Connected top cover 3 constitutes.

[0038] Such as figure 1 As shown, in the state where the top cover 3 is closed on the device main body 2, the device main body 2 and the top cover 3 are disposed at positions where the device main body 2 and the top cover 3 face each other, such as being fixed by a locking member 8. Structure.

[0039] On the front surface (hereinafter referred to as the front surface) of the figure close to the operator of the device main body 2, for example figure 1 A detergent / alcohol tray 11 that can be freely pulled out to the fron...

no. 2 Embodiment approach

[0124] Figure 10 It is a diagram schematically showing the configuration of a cleaning and disinfecting apparatus according to a second embodiment for supplying a gas-liquid two-phase flow in which ice particles are mixed into an endoscope channel, Figure 11 It is a partial cross-sectional view schematically showing a state in which a gas-liquid two-phase flow in which ice particles are mixed in gas is supplied into an endoscope channel to remove dirt.

[0125] The structure of the cleaning and disinfecting device of the second embodiment is the same as that of the above-mentioned Figure 1 to Figure 8 The cleaning and disinfecting apparatus of the first embodiment shown is different in that instead of liquid droplets, a gas-liquid two-phase flow in which ice particles are mixed in gas is used to clean the endoscope tube. Therefore, only this point of difference will be described, and the same reference numerals will be assigned to the same configurations as those in the fi...

Abstract

The invention provides an endoscope washing and disinfecting apparatus and method of washing endoscope using endoscope washing and disinfecting apparatus. The endoscope washing and disinfecting apparatus of the present invention includes an air pump supplying a gas to an endoscope channel included by an endoscope, a faucet supplying a liquid into the endoscope channel, a channel connectable to a mouthpiece of the endoscope channel included by the endoscope and supplying at least one of a gas or a liquid to the endoscope channel, and an injector converting the liquid into a liquid droplet, mixing the liquid droplet into the gas flowing in the channel with the size of the liquid droplet changeable, and thereby supplying gas-liquid two-phase flow in which the liquid droplet is mixed at a set ratio into the gas into the endoscope channel through the channel.

Description

technical field [0001] The invention relates to an endoscope cleaning and disinfection device for automatically cleaning and disinfecting an endoscope, and an endoscope cleaning method using the endoscope cleaning and disinfection device. Background technique [0002] In recent years, endoscopes have been widely used in the medical and industrial fields. The endoscope used in the medical field can observe the internal organs in the body cavity by inserting the elongated insertion part into the body cavity, or can use the treatment that is inserted into the through channel of the treatment tool included in the endoscope as needed. Utensils for various treatments. [0003] Endoscopes in the medical field are inserted into body cavities for the purpose of examination and treatment, and therefore, after use, they need to be cleaned and disinfected for reuse. As a method of cleaning and disinfecting the used endoscope, for example, a method using an endoscope cleaning and disin...
