A cartridge is provided for dialysis or other blood processing therapy. In the cartridge, fibers may be substantially uniformly distributed near a midplane, but near an end, in the inter fiber space, there may be void flow channels, which may cause fluid flow in the inter fiber space to transition within a short region to uniform flow with minimal stagnation zones. Void flow channels may be be radially oriented, introducing fluid from the outer circumference, or axially oriented, introducing fluid along the axial direction through passageways through the potting material. The fluid flow in the inter fiber space may be perpendicular to the fibers, or radial with respect to a cartridge longitudinal axis. The cartridge may have blood flow in the inter fiber space, and flow of dialysate or ultrafiltrate in the lumens of the fibers, or the opposite situation.

A dialysis system (e.g., a hemodialysis (HD) system) can be designed to operate in alternative environments, such as disaster relief settings or underdeveloped regions. The dialysis system can include a solar panel for generating electricity to power the dialysis machine and an atmospheric water generator for extracting water from ambient air. The extracted water can be used to generate dialysate and saline on-site. One or more of the components of the dialysis machine can be discrete components that are configured to facilitate fast shipping and simple on-site assembly (e.g., at a remote location). In some implementations, the discrete components may be configured to be attached to an existing dialysis system (e.g., a dialysis system designed for operation in a traditional environment) to permit the dialysis system to operate in an alternative environment.

A conductivity measurement device includes first and second conductivity measurement flow channels positioned in a fluid circuit and fluidly linked for fluid flow between the first and second conductivity measurement flow channels. A controller having a current source connected to the first and second conductivity channels applies alternating voltages at frequencies that are different, each being respective to one of the first and second conductivity cells.

Systems and methods include a heat transfer body with opposing major surfaces formed from a thermally conductive substrate in intimate thermal interaction with an alumina exterior surface that extends across the major surfaces of the body. In an illustrative example, the heat source may be a substantially planar, silicone-based heater source (P-SBHS). The heat transfer body may be configured to thermally interact, for example, heat from a heat source proximate a first of the major surfaces to a second of the major surfaces. A temperature sensor module may be located, for example, proximate to the first major surface such that a temperature sensor thermally interacts with the first major surface. The temperature sensor module may, for example, insulate the temperature sensor from the P-SBHS.

A CRRT apparatus comprising a filtration unit (2), a blood circuit (17), a blood pump (21), a dialysate line (13) and one or more lines (8; 51; 57; 58; 63; 69; 67; 74) to transfer a respective solution into blood; a fluid source for each of said one or more lines, wherein said solution comprises at least one buffer agent in the form of bicarbonate or bicarbonate precursor. A control unit (12) is configured to receive a patient prescription and to determine a parameter (J.sub.buffer_load/BW) indicative of a steady state acid-base balance in the blood of the patient who has to undergo a CRRT blood treatment, wherein said parameter is determined as a function of the concentration of said buffer agent in said fluid source and as a function of the estimated or calculated patient systemic steady state concentration of bicarbonate and/or bicarbonate precursors.

The invention pertains to a medical device: an ECMO (extracorporeal membrane oxygenation) catheter which can be used during right heart and lung failure. It pertains to a dual lumen catheter with a single port of entry which when in place bypasses the right heart and lungs while completing the veno-arterial circuit.

In one aspect, a system includes a blood treatment machine; a dialyzer configured to be coupled to the blood treatment machine, the dialyzer including a dialyzer housing defining a blood inlet and a blood outlet; a bundle of hollow fibers within an interior of the dialyzer housing; a pumping device drivable to force blood received from the blood inlet through lumens of the bundle of hollow fibers and out the blood outlet; a dialysate inlet port in fluid communication with a dialysate flow path that includes space in the interior of the dialyzer housing between the bundle of hollow fibers; and a dialysate outlet port in fluid communication with the dialysate flow path. The system further includes a fluid conditioning system configured to (i) prepare and supply fresh dialysate to the dialyzer via the dialysate inlet port, and (ii) receive spent dialysate from the dialyzer via the dialysate outlet port, recycle the spent dialysate, and supply the recycled dialysate to the dialyzer via the dialysate inlet port.

The present disclosure relates to a set, encompassing or consisting of an effluent bag for receiving effluent generated during a blood treatment having precisely one closeable opening or connection to an outside of the effluent bag, wherein the effluent opening includes a first connector of a first type, or is connected to such an adapter having a line section for guiding a fluid, whereby the line section includes a second connector of the first type and a third connector of a second type, wherein the second type is different than the first type.
