MEDICAL SUCTION REGULATOR

摘要

PROBLEM TO BE SOLVED: To make it possible to smoothly execute the regulation of the suction pressure in a medical suction regulator. SOLUTION: A suction regulator body 1 is provided with a transverse hole 5 penetrating through this body. A valve rod 6 is mounted at this transverse hole 5. The suction regulator is provided with a flow passage communicating the transverse hole 5 and a discharge port and is provided with a flow passage through which a suction port and a piston chamber 11 formed on the inner side of a regulator cover 2 communicate with each other. The valve rod 6 is provided with a flow passage through which its front end face communicates with the discharge port side. A piston 12 is inserted to one side of the transverse hole 5 and a valve is constituted of the front end face of the piston 12 and the front end of the valve rod 6. The valve is opened and closed and the suction pressure is regulated by regulating the position of the valve rod 6, by which the medical suction regulator is constituted.
