摘要： Provided is: an access port member capable of avoiding reduction in the durability of a valve caused by welding and fixing of a body to a cap part; and a method of manufacturing the access port member. The access port member includes: a body 8 internally including a flow path 8b for circulating blood and having an opening 8c communicating with the flow path 8b; a valve 9 made of an elastic member covering the opening 8c and attached to an attachment part 8d of the body 8, the valve 9 including a slit 9a that makes a transition from a closed state to an open state when pressed by a tip 11a of a syringe 11 capable of collecting blood or injecting a drug; a cap part 10 welded and fixed to the body 8 with the valve 9 interposed therebetween and the slit 9a facing outward; and a depression 8e formed at a position between a welding part Y1 and the attachment part 8d of the body 8.

摘要： To provide a dialysate extraction device and a blood purification apparatus each configured such that the scattering of dialysate that may occur when a cap member is detached from a collecting part is prevented more assuredly. A dialysate extraction device includes a dialysate extraction port 14 including a collecting part 14a to which dialysate is collectable, a cap member 15 attachable to and detachable from the collecting part 14a of the dialysate extraction port 14, and a seal member 16 configured to seal the collecting part 14a with the cap member 15 attached to the collecting part 14a. The seal member 16 includes a close-fitting part 16a configured to seal the collecting part 14a by closely fitting on an outer peripheral surface of the dialysate extraction port 14, and a projection 16b projecting toward an inside of the collecting part 14a and having an outer peripheral surface 16ba that faces an inner peripheral surface 14aa of the collecting part 14a with a gap in between. The projection 16b defines an inflow route γ into which outside air is allowed to flow when the sealing by the close-fitting part 16a is undone.

摘要： The present invention provides a blood purification apparatus to which a blood circuit that allows a patient's blood to extracorporeally circulate and a blood purifier connected to the blood circuit and that purifies the blood in extracorporeal circulation are attachable, the blood purification apparatus including a dialysate introduction line through which dialysate is introduced into the blood purifier; a dialysate drain line through which waste dialysate resulting from blood purification performed by the blood purifier is drained from the blood purifier; and a concentration-detecting unit that detects a concentration of a predetermined substance in the waste dialysate resulting from the blood purification by the blood purifier and flowing through the dialysate drain line. The blood purification apparatus includes a control unit that establishes a state of equilibrium where the concentration of the predetermined substance in the waste dialysate flowing through the dialysate drain line and a concentration of the predetermined substance in the blood flowing through the blood circuit are equal or approximate to each other; a storage unit capable of storing a value detected by the concentration-detecting unit in the state of equilibrium as an equilibrium value; and a clearance-calculating unit that calculates clearance in accordance with the value detected by the concentration-detecting unit and the equilibrium value stored in the storage unit, the clearance being a figure of merit representing a degree of solute removal by the blood purifier.
