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.

This disclosure relates to a blood treatment system including a blood treatment machine, a dialyzer configured to be coupled to the blood treatment machine, a blood line having a first end configured to be connected to the dialyzer and a second end configured to be connected to a needle for insertion into a patient, and one or more sensors operable to transmit, to the blood treatment machine, data related to tension along the blood line. The blood treatment machine is configured to take action in response to the data received from the one or more sensors.

An attaching member to be attached to a blood purification apparatus including peristaltic pumps, the attaching member holding pump tubes to be squeezed in a predetermined direction by the respective peristaltic pumps for liquid delivery. The attaching member includes a body attachable to a predetermined position of the blood purification apparatus, and a holding portion attached to the body and that holds the pump tubes. The body has openings through which flexible tubes that each allow liquid to flow through are allowed to pass, and the flexible tubes are securable by being passed through the openings.

An attaching member is provided that is capable of releasing a load occurring on a pump tube that is being attached to or detached from a peristaltic pump so that the work of attaching or detaching the pump tube to or from the peristaltic pump can be performed stably. An attaching member to be attached to a blood purification apparatus including peristaltic pumps holds pump tubes to be squeezed in a predetermined direction by the peristaltic pumps for liquid delivery. The attaching member includes a body attachable to a predetermined position of the blood purification apparatus, and holding portions attached to the body and that hold the pump tubes. The holding portions are displaceable relative to the body by rocking.

The present teachings provide an attaching member that holds a flexible tube through which liquid related to blood purification treatment is made to flow. The attaching member is attached to a blood purification apparatus and includes an anchor portion defined by a slit in such a manner as to be separated from an other portion and to be foldable, the anchor portion being capable of anchoring the flexible tube when folded to be raised from the other portion.

The present teachings provide an attaching member to be attached to a blood purification apparatus including peristaltic pumps, the attaching member holding pump tubes to be squeezed in a predetermined direction by the respective peristaltic pumps for liquid delivery. The attaching member includes a body attachable to a predetermined position of the blood purification apparatus, and holding portions attached to the body and that hold the pump tubes. The holding portions are attached to edge portions on two opposite sides of the body, and flexible tubes that each allow liquid to flow through are to be placed in a central portion of the body, the central portion being positioned between the holding portion on one of the edge portions and the holding portion on the other of the edge portions.

A tubing set for a blood processing system includes a first connector, a first tube, and a second tube. The first connector is configured to connect to a separation device within the blood processing system, and has a first inlet configured to be fluidly connected to an outlet of the separation device. The first connector also has an outlet and a second inlet. The first tube fluidly connects to the outlet and fluidly connects the separation device and a blood component storage container. The second tube is fluidly connected to the second inlet and fluidly connects the separation device and a saline storage container. The second tube may include a second connector that connects to the saline storage container.

A renal failure therapy system (10) includes a dialyzer (102); a blood circuit (100) in fluid communication with the dialyzer (102); a dialysis fluid circuit (30) in fluid communication with the dialyzer (102); and an electrically floating fluid pathway (140) comprising at least a portion of the blood circuit (100) and at least a portion of the dialysis fluid circuit (30), wherein the only electrical path to ground is via used dialysis fluid traveling through machine (12) to earth ground (28), and wherein at least one electrical component (46, 90, 82, 66, 102, 116) in the at least a portion of the dialysis fluid circuit (30) of the electrically floating fluid pathway (140) is electrically bypassed.

The present disclosure relates to a medical device with respectively at least one hard part with fluid paths for guiding a medical fluid, for example blood through the hard part. The medical device 200 also includes a converter and a device for determining a characteristic of the device 200. The converter is arranged to measure the characteristic of the fluid, while the fluid is present in one of the fluid paths. The characteristic may be geometric characteristic, for example, a fluid path.
