A hemodiafiltration (HDF) system is provided for performing HDF treatment. The HDF system includes a mixing system for mixing nitric oxide (NO) with other chemicals to produce a dialysis fluid. The HDF system further includes an extracorporeal blood circuit that includes a filter for separating the dialysis fluid into a dialysate and NO spiked substitution fluid. The extracorporeal blood circuit also includes a dialyzer that receives the dialysate and a blood line connected to the dialyzer. The blood line includes admission points connected to the filter. The admission points are used to administer the NO spiked substitution fluid to the patient during the HDF treatment.

This invention relates generally to magnetic sensors and related systems and methods. In some aspects of the invention, a magnetic sensor assembly includes a housing configured to releasably hold a medical fluid tube and a sensor secured to the housing, the sensor configured to detect a change in a strength of a magnetic field when a medical fluid passes through the medical fluid tube.

It is disclosed an apparatus for extracorporeal blood treatment (1) having a control unit (15) connected to an ultrafiltration device (20) and to a fluid preparation section (30) of fresh dialysis liquid. The control unit (15) is configured to receive measured values of the change of blood volume, the amount of ultrafiltration volume, and conductivity or to the concentration for at least one substance in the blood (BV %.sub.mes(t); U.sub.Fmes(t), WL.sub.mes(t); Cb.sub.mes(t)); the control unit (15) is also configured to receive prescription values for the same parameters and to control ultrafiltration and adjust conductivity in the fresh dialysis liquid based on the difference between said measured values and said prescription values.

A hemodialysis apparatus 1 is provided with a dialyzer 2 for performing hemodialysis, a blood circuit 3 connected to the dialyzer, a dialysis solution circuit 4 connected to the dialyzer, a replacement fluid port 31 provided in the dialysis solution circuit and capable of being opened and closed by a lid member, and a replacement fluid passage 6 having its one end connected to the blood circuit and the other end connected to the replacement fluid port.

Dialysis systems comprising actuators that cooperate to perform dialysis functions and sensors that cooperate to monitor dialysis functions are disclosed. According to one aspect, such a hemodialysis system comprises a user interface model layer, a therapy layer, below the user interface model layer, and a machine layer below the therapy layer. The user interface model layer is configured to manage the state of a graphical user interface and receive inputs from a graphical user interface. The therapy layer is configured to run state machines that generate therapy commands based at least in part on the inputs from the graphical user interface. The machine layer is configured to provide commands for the actuators based on the therapy commands.

The present disclosure relates to a filter module for a medical fluid delivery system capable of removing cytokine inducing substances (CIS) from a medical fluid.

A hemodiafiltration (HDF) system is provided for performing HDF treatment. The HDF system includes a mixing system for mixing nitric oxide (NO) with other chemicals to produce a dialysis fluid. The HDF system further includes an extracorporeal blood circuit that includes a filter for separating the dialysis fluid into a dialysate and NO spiked substitution fluid. The extracorporeal blood circuit also includes a dialyzer that receives the dialysate and a blood line connected to the dialyzer. The blood line includes admission points connected to the filter. The admission points are used to administer the NO spiked substitution fluid to the patient during the HDF treatment.

A system that fills multiple containers includes a filter with an inlet port and multiple outlet ports. The outlet ports are pre-attached to containers by respective filling lines of each container. Each container has an interior and each of the respective filling lines is connected to a respective container interior. All of the respective filling lines are sealed to the outlet ports and the containers such that the container interiors are isolated from an external environment except the inlet port, via the filter, forming a combined interior volume which is sterile. The system can produce batches of multiple sterile containers with sterile medicament in the containers.

Systems, methods, and devices for preparation of water for various uses including blood treatment are described. In embodiments, fluid is passed either by pump or passively by gravity feed, through various filtration elements from a fluid source to a treatment fluid container. The latter forms a batch that may be used during treatment. Methods and systems for creating multiple-treatment batches are described. Advantages of creating a multitreatment batch include the fact that the burden of treatment preparation can be reduced and the timing of the preparation of the batch can be independent of the treatment time. As described, there are various trade-offs and concerns with this approach which are addressed by the inventive embodiments.

This disclosure relates to detecting fluid in medical tubing. In certain aspects, a method is performed by a data processing apparatus. The method includes controlling repetitive activation of the ultrasonic transmitter. The method also includes receiving a signal from the ultrasonic receiver during an activation of the ultrasonic transmitter. The method also includes determining that fluid is absent or present in a portion of the medical fluid tube based on a comparison between the signal and a threshold value.
