体液流出管３は、腹水中に完全に浸っているので、体液
流出管３の開口４と腹水の接触面積が大きく、濃縮され
た腹水は弱いポンプの陰圧でも容易に導出することがで
きる。Since the body fluid outflow pipe 3 is completely immersed in the ascites, the contact area between the opening 4 of the body fluid outflow pipe 3 and the ascitic fluid is large, and the concentrated ascites can be easily discharged even with a negative pressure of a weak pump.
開口４は、メッシュ状フィルター６で覆われているの
