An extracorporeal and drug delivery system includes a renal failure therapy machine operable with a blood filter in fluid communication with an arterial line and a venous line, the machine including an effluent pump for pumping effluent from the blood filter, and at least one of a dialysis fluid pump for pumping dialysis fluid to the blood filter at a dialysis fluid flowrate, a predilution pump for pumping replacement fluid into the arterial line at a predilution flowrate, or a postdilution pump for pumping replacement fluid into the venous line at a postdilution flowrate; an infusion pump operable to deliver an intravenous (“IV”) drug to the patient; and a coordinating logic implementor configured to determine if a formulation adjustment should be made to the IV drug when a constituent of the IV drug exists in the dialysis fluid, the predilution replacement fluid, and / or the postdilution replacement fluid.

Presented is an airway organ bioreactor apparatus, and methods of use thereof, as well as bioartificial airway organs produced using the methods, and methods of treating subjects using the bioartificial airway organs. The bioreactor comprises: an organ chamber: an ingres line connecting the organ chamber and a reservoir system and comprising an arterial line, a venous line and a tracheal line; an egress line connecting the chamber and the reservoir system, pumps in ingress and egress lines; a controller to control fluid exchange; a chamber pressure sensor connected to the organ chamber.

The present disclosure describes systems and methods for blood return in a hemodialysis machine using an adjustable valve that includes a first portion having a first port configured to be connected to a machine arterial line and a second port configured to be connected to a machine venous line, and a second portion of the adjustable valve having an arterial inlet port configured to be connected to a patient arterial access line, a venous outlet port configured to be connected to a patient venous access line, and a substitution inlet port configured to be connected to a substitution fluid line. The first portion can be movable relative to the second portion to selectively connect the first port and the second port with a selected combination of two of the arterial inlet port, the venous outlet port, or the substitution inlet port to adjust a flow of fluid therethrough.

In one aspect a medical fluid connector functions as both a recirculation connector to connect arterial and venous lines during priming of an extracorporeal blood circuit as well as a clamp to occlude a fluid tube. In one aspect, the connector includes a tubular body with luer connections and a clamping arm that extends longitudinally along a tubular body to apply clamping force.

An extracorporeal and drug delivery system includes: (i) a renal failure treatment machine operable with a blood filter in fluid communication with an arterial line and a venous line, the machine including: (a) an effluent pump for pumping effluent from the blood filter at an effluent flow rate; and at least one of: (b) a dialysis fluid pump for pumping dialysis fluid to the blood filter at a dialysis fluid flow rate; (c) a pre-dilution pump for pumping replacement fluid into the arterial line at a pre-dilution flow rate; or (d) a post-dilution pump for pumping replacement fluid into the venous line at a post-dilution flow rate; (ii) an infusion pump operable to deliver an intravenous ("IV") drug to a patient at an IV drug flow rate; and (iii) a coordination logic implementer configured to adjust the IV drug flow rate based on an amount of the IV drug removed via the effluent flow rate.

An example medical system includes a hemodialysis device configured to receive blood from vasculature of a patient via an arterial line and to deliver blood to the vasculature of the patient via a venous line. The medical system includes a hematocrit sensor configured to generate a signal indicative of a hematocrit level of blood in at least one of the arterial line or the venous line. The medical system also includes processing circuitry configured to determine a change in blood volume of the patient over time based on the signal indicative of the hematocrit level, determine a threshold blood volume reduction over time for the patient, compare the change in the blood volume of the patient over time to the threshold blood volume reduction over time, and based on the comparison, generate an indication of vascular access recirculation.
