The closed circulation system test apparatus includes: a blood sending line for sending blood from the blood bag to the blood purification device via a blood pump; a blood returning line for sending blood exiting from the blood purification device to the blood bag via a resistance imparting means; a filtrate line for sending the filtrate exiting from a dialysate outlet of the blood purification device to the replacement fluid container via a filtrate pump; and a dialysate line for sending, via a dialysate pump, dialysate or replacement fluid from the replacement fluid container to a dialysate inlet of the blood purification device.

A blood-purification-treatment support system is capable of making an accurate judgement of whether or not any treatment conditions for blood purification treatment should be changed. The blood-purification-treatment support system is capable of supporting blood purification treatment. The system includes a storage device that stores patient-specific patient data that are acquired on a plurality of days including at least no-treatment days on which blood purification treatment is not conducted, an estimating device that compares the patient data for the plurality of days stored in the storage device with one another and estimates a pre-treatment patient state regarding blood purification treatment, and a judging device that judges from the pre-treatment patient state estimated by the estimating device whether or not any treatment conditions for blood purification treatment should be changed.

A method comprising: establishing a wireless connection between a first medical device and a second medical device, comprising: receiving, by the first medical device, via a short-range wireless technology protocol, connection information related to the second medical device; and establishing, by the first medical device, a wireless connection with the second medical device based on the connection information.

Systems, methods, and/or apparatuses may be operative to perform a dialysis process that includes a displacer infusion process. The dialysis machine may include at least one processor and a memory coupled to the at least one processor, the memory comprising instructions that, when executed by the processor, may cause the at least one processor to access dialysis information for a dialysis process performed by a dialysis machine, the dialysis information indicating a target substance to be displaced from a binding compound by a displacer, and determine an infusion profile for infusing the displacer into a patient during a displacer infusion process of the dialysis process, the infusion profile determined based on the dialysis information and an infusion constraint. Other embodiments are described.

A computer-implemented method comprises providing a fluid circuit comprising fluid pathways configured to mount and associate with a durable processing device comprising a pressure sensor in communication with a controller and a fluid pathway. A container is connected to the pressure sensor and may receive a volume of fluid. A change in pressure values between a first and second time is measured from when the volume of fluid is not in communication with the pressure sensor to when the volume of fluid is in communication with the pressure sensor, the volume of fluid within the container or a presence or absence of a fluid connection to the fluid pathway based on the change in pressure values is determined, and a response action is executed if the volume of fluid within the container is not within an authorized volume range for the time period, or if a fluid connection is unauthorized.

A hemodiafiltration system with a disposable pumping unit is disclosed. An example system includes a medical fluid pump actuator, a medical fluid heater, a blood filter and a disposable unit. The example disposable unit includes a medical fluid cassette portion including a medical fluid cassette housing configured to be operatively connected to the medical fluid pump actuator to pump medical fluid through the medical fluid cassette portion when the medical fluid cassette portion is in fluid communication with a medical fluid source. The example medical fluid cassette portion is also configured to be placed in fluid communication with the blood filter and with an extracorporeal circuit communicating with the blood filter, the fluid communication enabling hemodiafiltration to be performed. The example disposable unit also includes a heater bag configured to be placed in operable communication with the medical fluid heater and in fluid communication with the medical fluid cassette portion.

The invention relates to a blood treatment device, having the following:

a fluid line system (10) for guiding a fluid flow comprising a line portion (14), wherein the line portion (14) can be formed as a closed fluid system, and comprising at least one first concentrate supply line (26) for supplying a first concentrate solution; a fluid pump (11) for conveying the fluid in the fluid line system (10); a determining means (13; 23; 33; 29) for capturing a state of the fluid line system (10); a control unit for controlling the fluid flow; characterized in that the control unit is configured in such a way that the line portion (14) only forms a closed fluid system when the state captured by the determining means (13; 23; 33; 29) meets a predetermined condition.

A dialysis system includes a dialysis apparatus, a measurement apparatus, and a control apparatus. The dialysis apparatus performs hemodialysis on a dialysis subject. The measurement apparatus measures a cerebral regional oxygen saturation of the dialysis subject. The control apparatus adjusts a hemodialysis operating condition by the dialysis apparatus so as to suppress decrease in the cerebral rSO2 based on the cerebral rSO2 of the dialysis subject measured by the measurement apparatus during operation of the hemodialysis by the dialysis apparatus.

A system and method for controlling a renal therapy device is provided. The system comprises a controller for performing a method comprising: receiving a first power level of a first battery to determine if the first power level of the first battery is above a threshold value and receiving a second power level of a second battery to determine if the second power level of the second battery is above the threshold value. When the first power level is above the threshold value, the controller causes the renal therapy device to be powered by the first battery. When the first power level is below the threshold value, and the second power level is above the threshold value, the controller causes the renal therapy device to be powered by the second battery. The first battery is electrically isolated from the second battery.

The present disclosure relates to a calculation device for determining an interdialytic sodium intake of a patient and/or for determining a non-osmotically triggered interdialytic liquid intake, including a storage device and/or an input device configured for storing or for entering parameter values of the patient; a computing device, configured for calculating the interdialytic sodium intake of the patient and/or for calculating his non-osmotically triggered interdialytic liquid intake; and an output device for outputting a signal for controlling or closed-loop controlling a communication device and/or a medical blood treatment apparatus.
