As is well known, an endoscope has a body and a flexible insertion portion extending from the body,
The insertion section is inserted into the body cavity for observation. After using the endoscope, in order to prevent bacterial infection or the like to the next patient, the insertion part or the like inserted into the body must be washed and disinfected, but this part is long and slender, so it is difficult to perform sufficient washing. Therefore, conventionally, a disinfection method such as wiping with alcohol cotton was taken after each use, but if you continue to wipe with alcohol for a long time, problems such as deterioration of the coating of the insertion part and loss of smoothness occur, A cleaning device that can effectively clean an endoscope in a short time has been desired.

As an endoscope cleaning apparatus of this type, for example, "Otolaryngology"(84:11; 1615-1623, 19).
In 91), a device as shown in FIG. 12 has already been proposed. The endoscope 1 includes a body 2, an eyepiece portion 3 formed at one end of the body 2, and an insertion portion 4 extending from the other end of the body 1.
And a tip 5 attached to the tip of the insertion section 4. In this case, particularly careful cleaning is required for the insertion section 4 and the tip 5 inserted into the body. An illumination window and an observation window are formed in the tip 5 as is well known.

The endoscope cleaning apparatus of the above document includes a cleaning tube 100 having a length capable of accommodating the entire length of the insertion section 4. The cleaning pipe 100 has a straight pipe 101, a connection cylinder 102 coaxially connected to the pipe 101 at the upper end of the pipe 101, and an elbow pipe 103 provided at the lower end of the pipe 101. The elbow tube 103 has a vertical portion 10
3a is fixed to the pipe 101, and the horizontal portion 103b extends orthogonally to the pipe 101. The pipe 101 and the connecting cylinder 102 are provided as a straight pipe portion of the cleaning pipe 100, and the horizontal portion 103b of the elbow pipe is provided as a discharge pipe portion. One end of a water conduit 110 orthogonal to the connecting tube 102 is connected to the connecting tube 102. The water conduit 110 is connected to a wash water supply source, for example, a faucet of a water supply via a water supply pipe 111.

The above-mentioned endoscope cleaning apparatus includes the above-mentioned cleaning pipe 100.
And a support 12 for supporting the water conduit 110 and the endoscope 1.
It has 0. The support tool 120 includes a plate 121.
Is equipped with. A pair of supports 122, which are vertically separated, are attached to the front surface of the plate 120. The circular arc portion 122a of the support 122 supports the connecting tube 102 of the cleaning pipe 100, and the water guiding pipe 110 is sandwiched between the supports 122 to support the cleaning pipe 100 and the water guiding pipe 110.

Further, the plate 121 is provided with another pair of supports 123 which are separated from each other on the left and right. These support 1
The space | interval of 23 is narrowing toward the downward direction. When the insertion portion 4 of the endoscope 1 is inserted into the cleaning tube 100, the body 2 of the endoscope is locked to the support 123. In this locked state, the tip of the insertion portion 4 of the endoscope 1, that is, the tip 5
Are arranged near the corners of the elbow pipe 103.

When the washing water, for example, tap water is flowed at a constant flow rate from the hose 111 and the water conduit 110 to the connecting cylinder 102 of the washing pipe 100 while the endoscope 1 and the washing pipe 100 are supported, most of the washing water is discharged. Flows downward and flows while washing the outer peripheral surface of the insertion portion 4, then the flow is refracted in the horizontal direction by the elbow pipe 103 and flows out in the horizontal direction. At this time, since turbulent flow occurs due to refraction inside the elbow tube 103,
The cleaning effect of the tip 5 at the tip of the insertion part 4 is enhanced. On the other hand, a part of the wash water that has flowed in is washed by the washing pipe 1.
00 from the upper end so that a good cleaning effect can be obtained up to near the upper end of the insertion section 4.

[0007]
