The invention relates to a water treatment system (1) for dialysis treatments, wherein the water treatment system (1) comprises a permeate circuit with a reverse osmosis system (RO) and at least one tap (ES.sub.1, 2 . . . N) for permeate, whereby the reverse osmosis system (RO) is fed by the reflux of the at least one tap (ES.sub.1, 2 . . . N) for dialysis treatments and/or a raw water inflow (RZ), whereby the water treatment system further comprises a heat exchanger (WT), whereby a primary circuit (PK) of the heat exchanger (WT) is connected with a buffer tank (PT) for storing thermal energy, whereby a second circuit (SK) of the heat exchanger (WT) is integrated into the permeate circuit, whereby heat is transferred in a controlled manner from the buffer tank (PT) via the heat exchanger (WT) to permeate in the permeate circuit.

Blood treatment/dialysis systems are disclosed. The systems include a water treatment unit, preferably of the reverse osmosis type, whose outlet has connected thereto a water supply line provided with a number of branch connections having fluidly coupled thereto blood treatment/dialysis machines in a selective manner, and a drain line through which exhausted blood treatment fluid can be discharged from fluidly coupled blood treatment/dialysis machines. Also disclosed is a machine-external heat exchanger, which is connected to the water supply line upstream of the branch connections on one side and to the drain line on the other side.

The present invention relates to a blood treatment device having a heat exchanger which has a first space and a second space, wherein the first space is flowed through by a first fluid and the second space is flowed through by a second fluid, and wherein the heat exchanger has a membrane which separates the first space from the second space, wherein the membrane forms a component of a capacitor which has two capacitor plates between which the membrane is located, and wherein monitoring means are provided which are connected to the capacitor and which are configured such that they detect an electrical property of the capacitor for the purpose of detecting a leak from the first space to the second space.

A leak may be detected in a heat exchanger of a hemodialysis device. A drain valve is opened by the controller, and then closed by the controller after a pre-selected time period. An initial pressure is determined in the spent dialysate circuit and stored in the memory. A system pressure is determined at periodic time intervals and compared to a pre-determined maximum pressure. The controller then determines whether the heat exchanger has a leak, in that in response to the system pressure exceeding a predetermined maximum pressure, a command is generated to execute an event including suspending a disinfectant operation with a disinfecting agent, and in response to the initial pressure subtracted from the system pressure being greater than a predetermined minimum pressure differential, a command is generated to execute an event including suspending the cleanse operation with the disinfecting agent.

A peritoneal dialysis (PD) system includes a housing and a dialysis fluid pump housed by the housing. The dialysis fluid pump includes a reusable pump body that accepts PD fluid for pumping and a flush flow port. The PD system also includes a dialysis fluid heater for heating PD fluid, a container configured to accept and hold PD fluid, a condenser in fluid communication with the container, a chamber in fluid communication with the condenser and a flush flow line extending from the chamber to the flush flow port. The PD system further includes a control unit programmed to cause the dialysis fluid heater to heat PD fluid in the container to form steam or water vapor. The steam or water vapor is condensed in the condenser into distilled water collected in the chamber and provided from the chamber to the flush flow port via the flush flow line.

A dialysis system includes a filtration system capable of filtering a water stream, a water purification system capable of purifying said water stream in a non-batch process, a mixing system capable of producing a stream of dialysate from mixing one or more dialysate components with the water stream in a non-batch process, and a dialyzer system.
