A blood pump for causing blood to flow in one direction is used for a blood oxidation system that circulates blood in a body to an oxidizer so as to supply oxygen into the body from outside the body. The blood pump includes an outer wall having a gas outlet port formed through a lateral surface thereof; a blood chamber having a pouch which is inserted into the outer wall and of which opposite ends are connected to opposite ends of the outer wall, respectively; a pump injection valve fluid-communicably coupled to one end of the blood chamber and blocking blood from flowing to the blood chamber; and a pump discharge valve fluid-communicably coupled to the other end of the blood chamber and blocking blood from flowing from the blood chamber.

A system for regulating blood flow in extracorporeal circulation, and including a blood reservoir to receive blood from a patient, an oxygenator to condition the blood, a centrifugal pump to pump the blood from the blood reservoir to the oxygenator and back to the patient, an electronic remote clamp to regulate flow of the blood, and a controller to operate in a flow control mode and a speed control mode. The controller includes an operational element to set a blood flow value in the flow control mode and to set a speed of the centrifugal pump in the speed control mode. The controller to automatically switch between the flow control mode and the speed control mode in response to one or more trigger conditions and to automatically switch between the speed control mode and the flow control mode in response to opening the electronic remote clamp.

An access device may be provided that includes a hub configured to improve the flow of blood within a lumen, in order to prevent, e.g., thrombus formation, while also avoiding hemolysis. The hub may have a removably attachable second arm, protrusions/depressions with the lumens of the hub or system, and/or plugs or plug analogs may be used to prevent flow from entering certain regions of the lumens within the hub. These hubs may be used, e.g., as part of an access device, which may have a modular configuration.

A blood pump-oxygenator system comprises at least one blood pump, an oxygenator, inflow and outflow cannulas, connected to form a closed series circuit operable as a cardiopulmonary bypass system for extracorporeal processing of the patient's blood. The blood pump conveys blood through the circuit from the patient into the inflow cannula, through the oxygenator and out of the outflow cannula back into the patient. A manifold is connected between the inflow and outflow cannulas so blood passes through the manifold, wherein the manifold accommodates the blood pump and the oxygenator to form a recirculation loop configured to recirculate at least part of the blood in the circuit so the blood passes over the oxygenator multiple times. An extra blood pump is positioned at the outflow cannula to deliver a set volume to the patient, controllable independently from the blood pump that circulates the blood in the manifold including the oxygenator.
