Claim:
1. A dialysate extraction apparatus comprising: a dialysate extraction device having an inlet and an outlet which are connected to a flow route of a liquid and which circulates the liquid, and having a collection port which collects the liquid that is circulated; and an on-off device which is attachable to and detachable from the collection port of the dialysate extraction device and which turns on and off the collection port, wherein in a state where the on-off device is attached, the collection port defines a guide route which guides the liquid introduced from the inlet to a tip side of the collection port, and a discharge route which discharges the liquid guided by the guide route back through the collection port to the outlet; wherein the dialysate extraction device has a cylindrical outer peripheral wall which covers an outer periphery of the collection port, and wherein the on-off device includes a sealing device which seals between the on-off device and an outer peripheral surface of the outer peripheral wall or between the on-off device and a tip surface of the outer peripheral wall; and wherein the collection port is connected to a connection line for circulating an extracted liquid via a connection device, and wherein the connection line is connected to the collection port by fitting an inner peripheral surface of the connection device into the outer peripheral surface of the collection port and by engaging an outer peripheral surface of the connection device with an inner peripheral surface of the outer peripheral wall.
