Blood filtration systems
20210379264 · 2021-12-09 ·

A blood filtration system can reduce the amount of plasma constituents (e.g., water and/or electrolytes) in the blood of the patient, and accordingly increase the hematocrit value of the patient. The blood filtration system (e.g., a controller, or the like) can determine a hematocrit value of a patient. The blood filtration system can determine a venous pressure of vasculature of a patient. The blood filtration system can compensate for pressure head in a component of a blood circuit (e.g., a withdrawal line of a catheter), for example to improve the accuracy of the venous pressure determination. The blood filtration system can determine one or more resistance characteristics of a blood circuit for the blood filtration system. The resistance characteristics can correspond to a resistance to a flow of blood through a component of the blood circuit.

APPARATUS, SYSTEMS, AND METHODS FOR PERCUTANEOUS PNEUMATIC CARDIAC ASSISTANCE

A cardiac assist system includes a pneumatic effector which is implanted beneath a pericardial sac and over a myocardial surface overlying the patient's left ventricle. A port is implanted and receives a percutaneously introduced cannula. The port is connected to supply a driving gas received from the cannula to the pneumatic effector. An external drive unit includes a pump assembly and control circuitry which operate the pump to actuate the pneumatic effector in response to the patient's sensed heart rhythm. A connecting tube has a pump end connected to the pump and a percutaneous port-connecting end attached to the implantable port.

TUBE CONNECTOR, EXTRACORPOREAL CIRCULATION CIRCUIT, AND BLOOD PURIFICATION DEVICE
20210346669 · 2021-11-11 · ·

A tube connector is configured to connect between a main tube and a peristaltically-actuated tube. The tube connector includes a first connection part configured to be connected to the main tube; a second connection part configured to be connected to the peristaltically-actuated tube; a communication part being provided between the first connection part and the second connection part and having a communication flow path for communicating between a first flow path through which fluid flows in the first connection part and a second flow path through which the fluid flows in the second connection part; and a main body section. The first flow path and the second flow path are formed to have a constant diameter and are formed so as to extend along the axial direction of the main body section. A diameter of the first flow path is smaller than a diameter of the second flow path. The communication flow path is formed so as to gradually enlarge in diameter from a first flow path side to a second flow path side. A central axis of the first flow path and a central axis of the second flow path are shifted toward the radial direction of the main body section.
