摘要： A blood purification apparatus including an apparatus body to which a medical component for giving blood purification treatment to a patient is to be attached; a storage unit that stores treatment information regarding the blood purification treatment for the patient; a reading unit capable of reading component information of the medical component held by an information-holding unit; and a verifying unit capable of comparing the component information read by the reading unit and the treatment information stored in the storage unit and verifying whether or not the medical component is appropriate for being attached to the apparatus body. The medical component is sealed in a sterile bag before being attached to the apparatus body. Furthermore, the reading unit is capable of reading the component information in the information-holding unit from an outside of the sterile bag.

摘要： A blood purification apparatus capable of performing pre-substitution and post-substitution simultaneously is provided. A patient's blood flows through an arterial blood circuit and reaches a dialyzer. The blood purified by the dialyzer flows through a venous blood circuit and returns into the patient. A first substitution pump delivers substitution fluid through a substitution line to a branching point. A pre-substitution line connects the branching point and the arterial blood circuit to each other and is provided with a second substitution pump at a halfway position thereof. A post-substitution line connects the branching point and the venous blood circuit to each other and is provided with a check valve at a halfway position thereof. When the two pumps are activated simultaneously, the substitution fluid is supplied to the arterial blood circuit (pre-substitution). When only the first substitution pump is activated, the substitution fluid is supplied to the venous blood circuit (post-substitution). When the flow rate of the second substitution pump is set higher than the flow rate of the first substitution pump, pre-substitution and post-substitution are performed simultaneously.

摘要： A blood purification apparatus that includes a blood circuit including an arterial blood circuit and a venous blood circuit and that allows a patient's blood to extracorporeally circulate, with a blood purifier that is interposed between the arterial blood circuit and the venous blood circuit and purifies; a dialysate temporary chamber that temporarily stores dialysate received from a dialysate storage supported by a supporting unit; a substitution-fluid temporary chamber that temporarily stores substitution fluid received from a substitution-fluid storage supported by the supporting unit; a first dialysate introduction line through which the dialysate in the dialysate storage flows into the dialysate temporary chamber; and a substitution line through which the substitution fluid in the substitution-fluid storage flows into the substitution-fluid temporary chamber. The blood purification apparatus includes a dialysate transfer pump provided to the first dialysate introduction line and that transfers the dialysate in the dialysate storage to the dialysate temporary chamber, a substitution-fluid transfer pump provided to the substitution line and that transfers the substitution fluid in the substitution-fluid storage to the substitution-fluid temporary chamber, and a control unit that controls the dialysate transfer pump and the substitution-fluid transfer pump.

摘要： A blood purification apparatus including the following: a peristaltic pump that includes a stator to which a pump tube including a first portion and a second portion is detachably attached, and a rotor including a roller and a guide portion, the roller delivering liquid by squeezing the pump tube attached to the stator, the guide portion retaining the pump tube at an appropriate position where the pump tube is squeezable with the roller, the rotor being rotatable about a predetermined axis; an anchor member that anchors an attaching member to which the pump tube is attached; and a displacing portion that displaces the attaching member between a set position and an unset position by moving the anchor member with the attaching member being anchored by the anchor member. An attachable state in which the first portion of the pump tube rests at the appropriate position is established when the anchor member is moved from the unset position to the set position with the guide portion of the peristaltic pump being stopped in a specific phase.
