A connection portincludes a cylindrical outer portto which downstream piping(discharge-side piping) is connected; an inner portto which upstream piping(supply-side piping) is connected, and which is provided in the outer port; and a lid memberwhich closes the inner port as well as the outer port. The inner port is provided so as to extend through the outer port from the outside of the outer port, and a heater H is provided on a portion of the inner port projecting outside the outer port. When the lid member is in a closed state, the inner port is heated with the heater to sterilize the portion of the inner port exposed to the outside, thus enabling the connection port to be cleaned at a higher level.

Connection port and dialysis apparatus having connection port

A dialysis system operates to supply dialysate to a dialyzer from a feed chamber in response to a reduction in the volume of the feed chamber, and to recover used dialysate which is flowed out from the dialyzer into a recovery chamber in response to an increase in the volume of the recovery chamber. The increase in the volume of the recovery chamber is greater in magnitude than the magnitude of a reduction in the volume of the feed chamber, with a difference therebetween being effective to control the amount of ultrafiltration. At least two sets of feed chambers and recovery chambers may be provided, and a supply of the dialysate from the other feed chamber may be initiated before the supply from one of the feed chambers is completed, thus allowing the dialysate to be continuously supplied to the dialyzer.
