A mixing apparatus which can reliably prevent an auxiliary liquid from being unintentionally mixed into a main unit even when a failure occurs in a switching device, and which can prevent the switching device or an auxiliary flow route from being damaged even when a pressurizing device malfunctions due to the failure. The mixing apparatus includes a pipe circulating dilution water; a pipe circulating a disinfecting solution; a pressurizing pump circulating the disinfecting solution in the pipe toward the pipe; and a check valve capable of optionally turning on and off the pipe. The mixing apparatus further includes a discharge flow route which consists of a flow route branched from between the check valve and the pressurizing pump in the pipe, and which can discharge the dilution water or the disinfecting solution; and an electromagnetic valve which can control the flow route between the check valve and the pressurizing pump in the pipe to have a pressure lower than that of the pipe when not mixing the disinfecting solution with the dilution water.

In order to reduce the number of redundant sensors for measuring a property of process liquids in liquid-carrying production systems, there is proposed a measuring apparatus (100) for the online measurement of at least one property of process liquids at at least two different flow rates and during the production of a medical liquid, which measuring apparatus has a tank (4) for receiving the process liquid, a hollow accumulation vessel (7), which is arranged within the tank (4), in a side wall of the tank (4) or on a side wall of the tank (4) and through which the process liquid can flow depending on the filling level in the tank (4), said accumulation vessel having at least one lower opening (20) and at least one upper opening (30) which are fluidically connected to the interior of the tank (4) such that process liquid can flow from the hollow accumulation vessel (7) into the tank, and a sensor (6) for measuring at least one property of the process liquid, which sensor is arranged in the hollow accumulation vessel (7).

A blood purification device including: piping, a plurality of sensors, and a liquid chemical identification unit. The plurality of sensors of different detection types that are provided on the piping. The liquid chemical identification unit that identifies a type of a cleaning/disinfection liquid chemical flowing through the piping by using the plurality of sensors. The liquid chemical identification unit is configured to be able to identify types of the liquid chemicals of at least not less than a number of the plurality of sensors by using the plurality of sensors. The liquid chemical identification unit selects all or part of the plurality of sensors according to the type of the liquid chemical which should be used for cleaning/disinfection and, based on detection results from the selected all or part of sensors, identifies whether or not it is a liquid chemical which should be used for the cleaning/disinfection.

A centrally controlled multi-patient dialysis treatment system (1) as disclosed herein comprises: a dialysate preparation unit (2) configured to prepare a dialysate based on a prescription and control dialysate delivery for dialysis treatments in progress; one or more dialysate modules (3) configured to deliver the dialysate to a dialyzer (4) and control an ultrafiltration process; and one or more patient modules (5) configured to control an extracorporeal blood flow through the dialyzer (4) for the dialysis treatment, wherein the dialysate preparation unit (2), the dialysate modules (3) and the patient modules (5) are configured to be adapted to be assembled into an integrated dialysis treatment system suitable for one or more patients (6). Also an use of the centrally controlled multi-patient dialysis treatment system (1) for one or more patients' dialysis treatments is disclosed herein. For the centrally controlled multi-patient dialysis treatment system, in contrast to the conventional in-center dialysis infrastructures, in addition to cost saving, it is highly space efficient. Moreover, the centrally controlled multi-patient dialysis treatment system is robust and easy to setup.

A system includes an extracorporeal blood treatment device and a heat exchanger for heat exchange between dialysate flowing from the extracorporeal blood treatment device and permeate to be supplied to the extracorporeal blood treatment device. The extracorporeal blood treatment device and the heat exchanger are configured as separate devices.
