PROBLEM TO BE SOLVED: To provide a dialysis fluid extractor capable of making cleansing and sterilization inside a collection port be reliably performed, without extending a separate flow channel from opening/closing means.SOLUTION: A dialysis fluid extractor comprises: dialysis fluid extraction means 9 in which an introduction port 9a and a lead-out port 9b capable of circulating liquid are formed and a collection port 9c capable of collecting the circulated liquid is formed; and a cap 10 which is detachably attached to the collection port 9c of the dialysis fluid extraction means 9 and is capable of opening/closing the collection port 9c. The cap 10 includes: seal means 11 for performing sealing between the cap 10 and an outer peripheral surface of the collection port 9c; and defining means 12 for forming a guide passage α which defines the inside of the collection port 9c in a state of being fitted to the collection port 9c and guides liquid introduced from the introduction port 9a into the collection port 9c and an exhaust passage &bgr; for making liquid guided by the guide passage α be discharged into the lead-out port 9b side. |
