Abstract

PURPOSE: To prevent the invasion of filth in a branch pipeline, by arranging not only a suction pipeline almost horizontally but also branch pipeline almost vertically in an upward direction at a branch part.
CONSTITUTION: A branch pipeline 18 is formed so as to communicate with a suction tube 14 on the way thereof and a pressure detection part 16 for detecting the pressure in the suction tube 16 is provided to the branch pipeline 18 and intracoelomic pressure is detected through the suction tube 14 and the branch pipeline 18. Among tubes, the tubes 14a, 14b, 14c arranged on the way of the suction tube are horizontally arranged and the tubes 18a, 19a forming the branch pipeline branched by T-pipes 26, 26 are arranged almost vertically in an upward direction. Therefore, when filth passes through the suction tube, almost no filth invades in the branch pipeline.
