A dialysis monitor with a treatment fluid path configured to provide treatment fluid to a dialyzer when dialysis treatment is performed by the dialysis monitor is provided. A battery unit is connected to a controller and at least a portion of the functional elements of the dialysis monitor in order to provide back-up power should the supply of external power be discontinued. Energy of the battery unit is used to provide energy to the heater in preparation for and/or at least partly during thermal disinfection of the treatment fluid path or when starting up the preparation of treatment fluid thereby shortening the time required for the thermal disinfection and the starting up of the preparation of treatment fluid, respectively.

A blood treatment device includes a heat exchanger having a first space and a second space, with a first fluid flowing through the first space and a second fluid flowing through the second space. The heat exchanger has a membrane which separates the first space from the second space, with the membrane forming a component of a capacitor having two capacitor plates, between which the membrane is located. A monitoring means is connected to the capacitor, and is configured to detect an electrical property of the capacitor, for the purpose of detecting a fluid leak from the first space to the second space.

Dialysis machines comprising a feed arrangement to supply a dialysis fluid to a dialyzer during dialysis treatment and a return arrangement to remove the dialysis fluid from the dialyzer during dialysis treatment and forward it to an exit; a feed recirculation circuit to allow a fluid of the feed arrangement to be re-circulated in a fluid loop path comprising, at least a portion of, the feed arrangement and the feed recirculation circuit and a return recirculation circuit to allow a fluid of the return arrangement to re-circulate in an auxiliary fluid loop path comprising, at least a portion of, the return arrangement and the return recirculation circuit. A controller configured to perform disinfection by re-circulating a disinfectant and/or a heated fluid through said fluid loop path and/or through said auxiliary fluid loop path. The dialysis machine further comprises a feed forward arrangement connected to the fluid loop path and arranged to enable a fluid of the feed arrangement to be forwarded to the exit by-passing the auxiliary fluid loop path.

An integrated on-line monitoring and thermostatic heating apparatus for a bioartificial liver device, the apparatus including a blood inlet, a blood pump, an arterial drip chamber, a bioreactor module, a venous drip chamber, and a blood reinfusion port which are connected in sequence. The bioreactor module includes a thermostatic water tank and a bioreactor disposed in the thermostatic water tank. The bioreactor includes a container, and a first partition and a second partition which are disposed in the container. The first partition and the second partition separate the container into three independent parts, that is, a plasma separator, an oxygenator, and a reactor. The plasma separator and the oxygenator are connected through an external connection pipe. The external connection pipe is equipped with a separation pump. The second partition includes a communication hole, and the reactor and the oxygenator are connected through the communication hole.

A blood purification apparatus includes a line section, a duplex pump, and a control unit. The line section includes a dialysate introduction line and a drain-liquid discharge line. The control unit is configured to execute a blood purification treatment process and a defatting washing process. The blood purification treatment process is executed when blood purification treatment is performed in which dialysate is delivered to a dialyzer. The dialysate is prepared by mixing an A-drug solution and a B-drug solution introduced into the line section and diluting the A-drug solution and the B-drug solution to predetermined concentrations. The defatting washing process is executed when defatting washing is performed in which oil and fat in the line section is removed by causing a sodium carbonate solution to flow through the line section. The sodium carbonate solution is obtained by heating the B-drug solution introduced into the line section.

The control unit uses a heating unit and a deaerator when executing a bicarbonate-solution-generating process where the sodium carbonate solution is generated by a predetermined amount while carbon dioxide is discharged.

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 system includes a housing; a dialysis fluid pump housed by the housing; a patient line extendable from the housing; and a hose reel located within the housing, the hose reel configured to coil the patient line when disconnected from a patient. The patient line may be a dual lumen patient line, wherein the dual lumen patient line is coiled about the hose reel during a disinfection sequence for disinfecting the dual lumen patient line and the dialysis fluid pump.
