PROBLEM TO BE SOLVED: To provide an irrigator with a valve combined with an aspiration tube capable of manipulating both irrigation and aspiration with one hand or used together with the aspiration tube, the method of the use of the irrigator and the method for manufacturing the same. SOLUTION: A irrigator with a valve 10 provided with an aspiration tube 11 comprises a thin funnel 12 having an axis line penetrating an expanded entrance opening 15 made of a freely bendable elastomer, an out let extending tube 16 facing to the entrance opening. A flow path way 17 penetrating through the thin funnel 12 enables liquid communication by connecting the entrance and the out let. A web 19 crossing the entrance in the vicinity of the expanded entrance 15 tightly seals and separates the entrance from the out let. A gate 20 in the web 19 penetrates the web along the axis line and is made to be circular form to surround and liquid-tightly seal the aspiration tube 11. A lid 28 having a path way penetrating the entrance for irrigation and the aspiration tube closes the expanded entrance 15 to form a room 31 between the web 19 and the lid 28. A slit inside the web 19 forms a closed opening of a pair of seal tips. |
