Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an endoscope fluid control device in which a liquid delivery control conduit is detachably attached to an endoscope.

[0002]

[Prior Art]

 In recent years, endoscopes have been widely used in the medical field and industrial field. Since the endoscope has an objective lens at the tip of the insertion portion and is used by inserting it into the body or the like, the surface of the objective lens may be obstructed by the adherence of body fluid or the like. For this reason, air supply and water supply means are provided so that body fluids and the like can be removed. In addition, a treatment tool can be inserted to perform a procedure such as a biopsy, and a suction conduit or the like for sucking and removing unnecessary body fluid is provided.

As a conventional fluid control device, for example, as shown in Japanese Patent Publication No. 63-29538, there is known a technique in which a suction pipe line is detachable and replaceable. However, the air supply and water supply pipes and their control units were fixed inside the fluid control device, and even attachment / detachment and replacement were not provided.

[0004]

[Problems to be solved by the device]

 Needless to say, it is very dirty because low liquid, mucus, dirt, etc. in body fluids are sucked into the suction pipe line. The aspiration channel in the endoscope is especially the insertion part side, which is also an insertion passage for treatment tools, etc., and there is a risk of infection if it is not thoroughly cleaned and disinfected. However, since the fluid flows from the distal end side to the fluid control device side in the suction pipe line, if the suction pipe line inside the endoscope is thoroughly cleaned and disinfected, the inside of the suction pipe line inside the fluid control device becomes contaminated. However, the risk of infection is very low.

On the other hand, in the air supply and water supply pipelines, conversely, if intervening bacteria of tap water, fungi or pathogenic bacteria intervening in the hospital enter the device for some reason and the device is contaminated, The wash water that has passed through the closed conduit will enter the body cavity. In other words, the pollution source is on the upstream side, which is extremely dangerous. In particular, the water supply pipeline that allows water to pass through is prone to fungal growth in water and is extremely dangerous. In this way, in the conventional fluid control device, when the air supply pipe and the water supply pipe system are contaminated, it is necessary to disassemble the fluid control device and replace or disinfect the above-mentioned pipe system, which causes contamination. I had to send it out for repair every time.

The present invention has been made in view of the above points, and an object of the present invention is to provide an endoscope fluid control device capable of easily performing cleaning and disinfection operations.

[0007]

[Means and actions for solving problems]

 In the present invention, an air supply control means for controlling the supply of gas, an air supply control conduit for introducing gas into the conduit in the endoscope via the air supply control means, and a water supply control for controlling the supply of liquid. In an endoscope fluid control device having a liquid supply control conduit for introducing a liquid into a conduit provided in the endoscope via the water supply control means, at least the liquid supply control conduit is detachable. By making it possible to facilitate the cleaning work by removing the liquid transfer control conduit, or to replace it regularly, it is possible to always use it in a hygienic condition.
