A conveying device for conveying a medical fluid that is guided into a hose includes a rotor and a stator. The stator includes a stator base, an area for receiving the hose in the conveying device, and a hose bed providing a counter bearing for occlusion devices. The rotor includes a rotor axis and at least two occlusion devices that are attached radially to the rotor axis and that compress the hose intermittently against the hose bed during use of the conveying device. The rotor encompasses an axial guiding element that is arranged to rotate about its own longitudinal axis for aligning the hose in the stator. The longitudinal axis of the axial guiding element extends parallel to the longitudinal axis of the rotor axis. The axial guiding element includes a middle section and a first lateral section protruding radially over the middle section.

The present disclosure relates to a motor for an extracorporeal blood pump, an extracorporeal blood pump, and an extracorporeal blood pump system. The motor for an extracorporeal blood pump comprises: a housing; an actuator located in the housing and used for driving an impeller in a pump head of the extracorporeal blood pump; at least one sensor located in the housing; and a motor driving-control assembly located in the housing and used to control operation of the motor. Integrating the motor driving-control assembly into the housing of the motor can significantly reduce the dependence of the motor on the control host of the extracorporeal blood pump, the risk of communication failure between the motor and the control host, and the risk of malfunction of the motor driving-control assembly, thereby greatly improving the safety and reliability of the extracorporeal blood pump.

The disclosed subject matter relates to extracorporeal blood processing or other processing of fluids. Volumetric fluid balance, a required element of many such processes, may be achieved with multiple pumps or other proportioning or balancing devices which are to some extent independent of each other. This need may arise in treatments that involve multiple fluids. Safe and secure mechanisms to ensure fluid balance in such systems are described.

A pump for mimicking physiological blood flow in a patient is disclosed. The pump works via compression and decompression of a tube, inducing a peristaltic flow within the tube. The compression may be effected by a linear actuator, or alternatively by a pivoting compression member. A one-way check valve ensures flow in a single direction.

Embodiments of the present invention include a portable medical device with an integrated web server. The portable medical device is configured to establish a communication session with a user device. The integrated web server is configured to load software onto the user computing device for exchanging data with the portable medical device.

An aspiration system includes a plurality of catheters located at least partially within the lumen of an outer sheath. The outer sheath and the catheters are configured to slide relative to each other between a first state in which the distal ends of the catheters are located within the lumen of the outer sheath, and a second state in which the distal end and an end length section of each catheter is extended through the distal end of the outer sheath and outside of the lumen of the outer sheath. The end length section of each catheter is configured to spring or flare outward relative to the first state, when the outer sheath and the plurality of catheters are in the second state. The distal end of the outer sheath may be placed in an inferior vena cava or iliac vein in a transplant kidney patient, adjacent at least one renal vein, with the outer sheath and the plurality of catheters in the first state. Then, the system may be transitioned to the second state to cause the end length sections of the catheters to spring or flare outward adjacent the renal vein. The catheters are connected to a suction source for aspiration through the catheter end length sections.
