Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for cleaning an insertion portion of an endoscope used for medical purposes and the like into a body cavity.

[0002]

2. Description of the Related Art An endoscope used for medical purposes has to be cleaned each time it is used because it is inserted into the body, etc., but especially the insertion portion directly inserted into the body cavity is more complete. Must be washed. For this reason, conventionally, an endoscope is housed in a washing machine, and a cleaning liquid or a disinfecting liquid is sprayed on the entire body by a means such as a shower, or the endoscope is immersed in the cleaning liquid or the disinfecting liquid. I was trying to clean the whole mirror.

[0003]

By the way, as in the above-mentioned conventional cleaning apparatus, it takes a considerable amount of time to perform complete cleaning just by supplying the cleaning solution or the disinfecting solution. Moreover, after washing, it must be dried. Here, in the endoscope, a main body operation section is continuously provided at the proximal end portion of the insertion section, and further, a light guide soft section or the like is continuously provided at the main body operation section, and a distal end of the light guide soft section is provided. A light source connector is provided, and in the case of an electronic endoscope, an electrical connector is also provided in addition to this light source connector, but these main body operation part and light guide flexible part have complicated shapes. Therefore, wiping off the liquid with a cloth or the like is quite troublesome and time-consuming.

However, since the main body operation section and the light guide soft section are not directly inserted into the body cavity, it is not always necessary to clean or disinfect each case. Nevertheless, in the conventional cleaning device, the entire endoscope including the main body operation part and the light guide flexible part is cleaned. The operation of drying the endoscope is very time-consuming.

From the above points, in the conventional cleaning device, when the endoscope is used and stored,
Although it is suitable for cleaning the entire endoscope, it is not always suitable as a cleaning device for each case.

The present invention has been made in view of the above points, and an object thereof is to quickly and completely complete a necessary portion of an endoscope by a simple operation after use in one case. Another object of the present invention is to provide a cleaning device that can be cleaned.

[0007]

In order to achieve the above-mentioned object, the present invention has a cylindrical cleaning container into which an insertion portion of an endoscope can be inserted, and a brush is provided on an inner wall of the cleaning container. A liquid supply part is provided at the top of the plant and a liquid discharge part is provided at the bottom of the plant, and it is detachably connected to the tip of the insertion part to insert the insertion part into the cleaning container. It is characterized in that the partial retraction member is mounted.

[0008]

In summary, since the cleaning or disinfection performed for each case only needs to be performed on the insertion portion directly inserted into the body cavity, the present invention provides a cleaning container capable of cleaning only this insertion portion. I am using. Then, the cleaning liquid is supplied, but in order to perform the cleaning more quickly and completely, the surface of the insertion portion is brushed in addition to the supply of the liquid.

Then, the insertion portion retraction member is positioned above the cleaning container, and the tip of the insertion portion is connected to the insertion portion retraction member so as to be drawn into the cleaning container. Supply cleaning, disinfecting or rinsing solution from. As a result, the insertion part comes into contact with the liquid in the cleaning container, and while being brushed by sliding contact with the brush provided on the inner surface of the cleaning container, the insertion part enters the deep part of the cleaning container. It is easily and completely cleaned. Then, after inserting the insertion portion to a predetermined depth position of the cleaning container, it is pulled back, but since the rubbing with the brush is performed also at this time, the cleaning efficiency is further improved.

For example, if the disinfectant solution is supplied when the insertion part is inserted into the cleaning container and the rinse solution is supplied when the insert part is pulled out, the disinfection and the disinfectant solution can be washed out by one operation. Two types of work are performed. Also, when pulling back the insertion part, at a site outside the cleaning container,
If the insertion portion is covered with a cloth and pulled out, it is possible to remove water droplets attached to the surface of the insertion portion at the same time.
