It may have a branch passage 51b and a second branch passage 51c branched from the communication passage 51a and communicating with the suction pipe 40 . For example, the communication passage 51a may be formed on the upper part of the housing 51, the first branch passage 51b may be formed on one side of the lower part of the housing 51, and the second branch passage 51c May be formed on the other lower side of the housing 51.

The first valve 52 is installed in the first branch passage 51b, and the first valve 52 is moved to a first position to open the supply pipe 30 or to a second position to close the supply pipe 30. can be moved to a location.

For example, referring to FIGS. 11A and 11B , when the first valve 52 is moved to the first position, the communication passage 51a may have a first passage 52a communicating with the supply pipe 30. Specifically, one side of the first flow path 52a communicates with the communication path 51a and the other side of the second flow path 53a communicates with the supply pipe 30. Therefore, when the first valve 52 is moved to the first position, the washing water flowing from the supply pipe 30 passes through the first flow passage 52a and the communication passage 51a to the suction washing pipes 10a, 10b, and 10c. can be supplied with

Conversely, referring to FIGS. 12A and 12B , when the first valve 52 is moved to the second position, communication between the communication passage 51a and the supply pipe 30 by the first flow passage 52a is released. . Specifically, when the first valve 52 is moved to the second position, the body of the first valve 52 closes the end of the supply pipe 30, thereby opening the communication passage 51a by the first flow passage 52a. And the communication between the supply pipe 30 can be released.

The second valve 53 is installed in the second branch passage 51c, and the second valve 53 is moved to a third position for opening the suction pipe 40 or a fourth position for closing the suction pipe 40. can be moved to a location.

Specifically, one side of the second flow path 53a communicates with the communication path 51a and the other side of the second flow path 53a communicates with the suction pipe 40 . Therefore, when the second valve 53 is moved to the third position, the negative pressure of the suction pipe 40 is transmitted to the suction and washing pipes 10a, 10b and 10c via the second flow passage 53a and the communication passage 51a. It can be.

Conversely, referring to FIGS. 11A and 11B , when the second valve 53 is moved to the fourth position, communication between the suction pipe 40 and the communication passage 51a by the second flow passage 53a is released. . Specifically, when the first valve 52 is moved to the second position, the body of the first valve 52 closes the end of the supply pipe 30, thereby opening the communication path 51a by the second flow path 53a. Communication with the suction pipe 40 can be released.

Meanwhile, the first valve 52 may be moved to a first position by pressing the first button 54 or moved to a second position by releasing the pressing of the first button 54 .

The first button 54 pressurizes the first valve 52 to move the first valve 52 to the first position, or pressurizes the first valve 52 to release the first valve 52. It serves to move to position 2. For example, the first button 54 may pressurize the first valve 52 and move it to the first position by a user's push. As such, when the first button 54 is moved to the first position, the washing water flowing in the supply pipe 30 flows out through the suction washing pipes 10a, 10b, and 10c.

The second button 55 pressurizes the second valve 53 to move the second valve 53 to the third position, or pressurizes the second valve 53 to release the second valve 53. It serves to move to position 4. For example, the second button 55 may pressurize the second valve 53 and move it to the second position by a user's push. In this way, when the second button 55 is moved to the third position, the negative pressure formed in the suction tube 40 is transferred to the suction washer tubes 10a, 10b, and 10c, and thus the suction washer tubes 10a, 10b, and 10c contaminated water is sucked into

That is, when the first button 54 is pressed, the washing water flows out through the suction washing tubes 10a, 10b, and 10c, and when the second button 55 is pressed, the negative pressure of the suction tube 40 10a, 10b, 10c) and the contaminated water is sucked into the suction washing tubes 10a, 10b, 10c. However, if the user confuses the first button 54 and the second button 55 and presses the second button 55 when the first button 54 needs to be pressed, a medical accident may occur.

Therefore, a first identification portion 54a capable of recognizing the outflow of washing water from the suction washing tubes 10a, 10b, and 10c is formed on the outer surface of the first button 54 when the first button 54 is pressed. On the outer surface of the second button 55, when the second button 55 is pressed, a second identification portion 55a capable of recognizing the suction of contaminated water from the suction washing tubes 10a, 10b, and 10c is formed. can

For example, the first identification part 54a may have an intaglio or embossed shape, and may be formed in an I shape. In addition, the second identification part 55a may have an intaglio or embossed shape, and may be formed in an S shape.

According to the present invention, the suction washing tube and the suction washing device including the same according to an embodiment of the present invention can prevent a part of the organ of the treatment site from being sucked when polluted water is sucked from the treatment site.
