When sucking a fluid within a body cavity, foreign matter included in the fluid which exceeds the filtering diameter of a filtering apparatus may cause clogging of the filtering apparatus. Another concern is that a body cavity membrane getting stuck to a suction port of a suction tube may lead to the suction port being closed off. In response to such problems as these, provided is a suction apparatus (14), comprising a suction tube (24), and a filter member (26). The suction tube (24) has side holes (23) formed in a tube wall on a body cavity-side tail end part. The filter member (26) has a tubular cap shape and covers a tail end aperture (28) of the suction tube (24) and the side holes (23), is formed from a foam body with an average aperture opening of 500-1000 m, and has a thickness of 7.5 mm or more.

Provided is a blood purification apparatus that is capable of performing a liquid spill prevention operation and uniformizing the amount of air introduced through an opened portion. The blood purification apparatus includes a dialysate introduction line L1 that allows dialysate to be introduced into a dialyzer 9; a dialysate discharge line L2 that allows the dialysate introduced through the dialysate introduction line L1 to be discharged from the dialyzer 9; coupling tools C1, C2 that allow free switching between a connected state which causes the dialysate introduction line L1 and the dialysate discharge line L2 to form a closed circuit, and an opened state which causes the closed circuit to be opened to form an opened portion; and a control means 30 that performs a liquid spill prevention operation in which external air is introduced through the opened portion. An air detection means, by which air introduced through the opened portion is detectable, is provided in the vicinity of the coupling tools C1, C2, and the control means 30 stops the liquid spill prevention operation when air is detected by the air detection means.
