[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cleaning adapter for an endoscope, and more particularly, a connector portion is connected to an inlet portion of an air / water feeding pipe line and a suction pipe line which are arranged in parallel at a hand operation portion of the endoscope. The present invention relates to a cleaning adapter for an endoscope cleaning device that supplies cleaning liquid.

[0002]

2. Description of the Related Art An endoscope used for observing, inspecting, and diagnosing a living body cavity is used not only on its outer surface but also on an air / water supply pipe line and a suction pipe every time it is used after being detected for hygiene. The insides of various pipes such as a passage are also cleaned and disinfected by using the cleaning device 1 shown in FIG. The washer 1 includes connectors 3A and 3B attached to the distal end of a tube 2 and an inlet / portion 5A of an air / water supply pipe line and a suction pipe line that are arranged in parallel with the endoscope hand operation unit 4.
5B, respectively, and a cleaning liquid or a disinfecting liquid is supplied from the syringe 6 to simultaneously clean and disinfect the pipe lines.

Recently, the connectors 3A and 3B have been used.
There has been proposed a cleaning adapter 8 in which the connectors 3A and 3B are fixedly integrated with the space holding plate 7 shown in FIG. 5 so that the space therebetween becomes equal to the space between the inlet portions 5A and 5B. If this cleaning adapter 8 is used, the connectors 3A and 3B can be connected to the inlet portions 5A and 5B in one operation, so that the efficiency of the operation can be improved.

[0004]

However, in the conventional cleaning adapter 8, the connectors 3A and 3B and the inlet portion 5 are used.
If the gap between A and 5B is large, the connector 3
There is a drawback that A and 3B cannot be connected to the inlet portions 5A and 5B. From such a viewpoint, the connectors 3A, 3B are
It has been proposed that the connector 3A, 3B be provided with a play that absorbs the gap error. However, if the connector 3A, 3B is provided with a play, the watertightness of the connector 3A, 3B becomes insufficient, and water leaks from the connection portion during cleaning. There is a drawback that.

Further, if the connectors 3A and 3B are provided with play, the connection becomes loose. Therefore, a belt 9 (see FIG. 4) for fixing the cleaning adapter 8 to the endoscope hand operation section 4 is required. Further, when the belt 9 is used, there is a risk that the inlets 5A and 5B, and hence the inside of the conduit, may become dirty due to the contamination of the belt 9. The present invention has been made in view of the above circumstances, and provides a cleaning adapter for an endoscope that can absorb a gap in the connection interval between the inlets of various conduits and the connector without allowing the connector to have play. The purpose is to provide.

[0006]

In order to achieve the above-mentioned object, the present invention provides a plurality of connector parts connected to the inlet parts of a plurality of conduits arranged in parallel at the hand operation part of an endoscope. Have,
In a cleaning adapter for an endoscope held by a spacing member such that the spacing between these connector portions is substantially the same as the spacing between the inlet portions of the plurality of conduits, the spacing member is replaced by an elastic member. And a notch is formed between the plurality of connector portions, and the distance between the connector portions is adjustable.

[0007]

According to the present invention, even if the connection intervals between the plurality of inlet portions of the various pipelines and the plurality of connector portions are deviated,
When attempting to connect the connector part to each of the inlet parts, the portions of which the rigidity is reduced by the notch of the spacing member are elastically deformed in the direction in which the connector part is connected, so that the connector part is connected without play. Can absorb gaps in the intervals.

Further, since the connector portion is firmly connected to the inlet portion by the restoring force of the spacing member, the cleaning adapter can be fixed to the endoscope hand operation portion without using a belt or the like.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of an endoscope cleaning adapter according to the present invention will be described in detail below with reference to the accompanying drawings. In Figure 1,
1 shows the situation in which the endoscope cleaning adapter 10 according to the first embodiment of the present invention is connected to a hand operation portion of an endoscope, and is the same as or similar to that in the conventional example shown in FIG. Will be described with reference numerals.

The cleaning adapter 10 has a spacing plate 12 which will be described later, and the spacing plate 12 has connectors 3A,
The upper end of 3B is fixed. The connectors 3A, 3
B is connected by pushing the cleaning adapter 10 into the inlet portions 5A and 5B arranged side by side on the upper flat portion 4A of the endoscope hand operation portion 4, respectively. The inlet portion 5A is
The inlet 5B communicates with an air / water supply conduit (not shown) and the inlet 5B communicates with a suction conduit (not shown). The tips of the connectors 3A and 3B are designed to be easily fitted.

The spacing plate 12 is formed of an elastic member such as elastomer. In addition, the spacing plate 1
As shown in FIG. 2, holes 12A and 12B into which the connectors 3A and 3B are fitted are opened on the surface of 2, and a notch groove 14 is formed between the holes 12A and 12B.
As a result, the spacing plate 12 is easily elastically deformed in the three-dimensional direction with the portion 12C having a lower rigidity than the other portions due to the cut groove 14 as a base point.

According to the cleaning adapter 10 thus constructed, even if the distance l between the connectors 3A and 3B deviates from the distance L between the inlet portions 5A and 5B, the connector 3A,
When connecting 3B to the inlets 5A and 5B respectively, the spacing plate 12 elastically deforms in the direction of connecting the connectors 3A and 3B from the portion 12C with reduced rigidity as a base point, so that the connectors 3A and 3B are connected to the inlets 5A and 5B. 5A,
5B can be connected in one operation.

Therefore, by using the cleaning adapter 10 of the present embodiment, it is possible to absorb the gap in the connection interval without providing the connectors 3A and 3B with play. Further, since the connectors 3A and 3B are firmly connected to the inlet portions 5A and 5B by the restoring force of the spacing plate 12, the cleaning adapter 1 can be used without using the belt 9 (see FIG. 4) or the like as in the conventional case.

FIG. 3 shows a situation in which the endoscope cleaning adapter 16 according to the second embodiment of the present invention is connected to the hand operation unit 4. The spacing plate 18 of the cleaning adapter 16 is made of an elastic member such as elastomer and is formed into a substantially rectangular shape.
Further, on the surface of the spacing plate 18, a cutout hole 20 is opened between the connectors 3A and 3B, and the cutout hole 20 is formed in a direction orthogonal to the longitudinal direction of the spacing plate 18. As a result, the spacing plate 18 is easily elastically deformed in the three-dimensional direction with the bases of the portions 20C and 20C whose rigidity is lower than that of the other portions due to the cut holes 20.

As with the cleaning adapter 10 described in the first embodiment, the cleaning adapter 16 having the above-described structure has a gap 1 between the connectors 3A and 3B with respect to a gap L between the inlet portions 5A and 5B. , Connector 3A, 3B to the inlet portion 5
When trying to connect to A and 5B respectively, the spacing plate 1
Since 8 is elastically deformed in the directions in which the connectors 3A and 3B are connected with the portions 20C and 20C having reduced rigidity as base points, the connectors 3A and 3B can be connected to the inlet portions 5A and 5B by one operation.

Therefore, even the cleaning adapter 16 of the second embodiment can absorb the deviation of the connection interval without providing the connectors 3A and 3B with play. In the present embodiment, the spacing plates 12 and 18 are made of elastomer, but the material is not limited to this, and any material can be used as long as it can be elastically deformed by the force of pushing the cleaning adapters 10 and 16. But good.

[0017]
