  • Suction device with irrigation
    Patent number: 6932788
    Abstract: A suction device with an irrigation function exhibits reduced occurrence of jamming and can be easily manipulated. A flexible tube 21 is removably connected to a flexible tube connection 22 of a suction device body 20. A suction path 25 is substantially straightly aligned with the flexible tube connection 22. An irrigation path 27 is formed as a branch path of the suction path 25. When a rotation lever 31 is not pressed, the suction path 25 communicates with the flexible tube 21. As the lever 31 is pressed, the communication is disconnected and the irrigation path 27 begins to communicate with the flexible tube 21 through a zero point state.
