A medical fluid delivery system and apparatus for remote machine updating and control are disclosed. An example medical fluid delivery apparatus includes a processor and a dialysis fluid circuit including at least one dialysis fluid pump. The processor determines a dialysis treatment or a preprogrammed task is not being performed by the least one dialysis fluid pump. After determining a dialysis treatment or a preprogrammed task is not being performed, the processor activates a connectivity agent to communicatively couple to a server via a network. The processor then receives, from the server via the connectivity agent, a command message to perform a preprogrammed task. The processor next deactivates the connectivity agent to stop communication with the server and causes the at least one dialysis fluid pump to perform the preprogrammed task.

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.

A peritoneal dialysis apparatus includes a filter and a dialysis fluid circuit in fluid communication with the filter. The peritoneal dialysis apparatus also includes a pump for pumping fresh dialysis fluid to a peritoneum of a patient via the dialysis fluid circuit and pumping used dialysis fluid from the peritoneum of the patient through the dialysis fluid circuit and the filter. The peritoneal dialysis apparatus further includes a selective air access in fluid communication with the dialysis fluid circuit and a control unit configured to control the pump during a peritoneal dialysis treatment and a filter cleaning sequence. The control unit forms a fluid mixture during a filter cleaning sequence by opening the selective air access to mix air with a physiologically safe fluid. The fluid mixture is transferred across insides and/or outsides of the filter at least one time.

The invention relates to a blood treatment device, in particular a device which can perform haemodialysis and haemodifiltration procedures. This is achieved using an interconnected pump and valve arrangement which can be controlled to direct fluid across a dialysis membrane or parallel to said membrane depending on the type of processing required. This allows dynamic variation between modes of operation and treatment.

The present invention concerns an electronic safety system for an RO device which is configured to be used with at least one dialysis device (e.g., a hemodialysis or a peritoneal dialysis device). The system comprises the RO device, which is configured for the production of ultrapure water and which includes a sensor unit for collecting sensor data and whereby the RO device comprises an electronic data interface in order to send the sensor data collected by the sensor unit; and it also comprises an analysis unit which is configured to analyze a water sample with regards to safety requirements and for example with regard to contamination and to generate result data whereby the analysis unit also includes an analysis interface in order to send the generated result data in electronic form; and a network for the data exchange between the medical entities, for example between the RO device and the analysis unit.

The present invention relates to extracorporeal blood treatment devices and methods and devices for conserving extracorporeal blood treatment devices. In accordance with the present invention, an antifreeze agent in introduced only into that part of the dialysis liquid system of the blood treatment device that includes the volume lying upstream of a sterile filter with which sterile substituate is recovered from the dialysis liquid. Accordingly, that part of the dialysis liquid system that includes the volume lying downstream of the sterile filter is not filled with an antifreeze agent. The present invention makes it possible, after removal of the sterile filter, to easily and safely separate a substituate segment from the rest of the dialysis liquid system and drain off liquid located in the substituate segment.

The device for producing ultrapure water according to the reverse osmosis principle with a reverse osmosis filter which is subdivided by the RO membrane into a primary chamber and a secondary chamber, with a primary circuit through which raw water is supplied to the primary chamber and concentrate is discharged therefrom, and with a secondary circuit for supplying permeate to at least one consumer, preferably to a dialysis device, is characterized in that a means for detecting organic and/or inorganic deposits is arranged in or on the primary circuit and/or the secondary circuit and is connected to an evaluation means.

A method includes collecting used dialysis fluid in a container and combining the dialysis fluid with an acid to lower the pH value of the used dialysis fluid.

The invention relates to a device for discharging wastewater, in particular used or spent dialysate, comprising a plurality of line connections 3, 4, 5 for connecting wastewater lines, in particular wastewater lines of dialysis machines. The device according to the invention is designed as a part which can stand on the bottom of a basin. Sufficient stability can be achieved on account of the weight (gravitational force) of the device alone, without it being necessary to secure the device. Recontamination is prevented effectively in that the line connections 3, 4, 5 are in fluid connection with at least one inflow line, the lower end of which is arranged so as to be spaced apart from the bottom, such that a free-fall distance is formed. In a preferred embodiment, a casing 1 surrounds the at least one inflow line 6, 7, 8. The casing 1 forms a splash guard in the form of a hood such that the wastewater, which emerges from the inflow lines 6, 7, 8 under relatively high pressure, cannot reach the surroundings.

The blood purification system includes a plurality of monitoring devices (1) with a dialyzer (5) to perform a blood purification treatment on a patient. A dialysate supplying device (2) supplies a dialysate to each of the monitoring devices (1). The plurality of monitoring devices (1) and the dialysate supplying device (2) are connected to each other by a LAN cable . Predetermined information can be transmitted from the dialysate supplying device (2) to a specified monitoring device (1), out of the plurality of monitoring devices (1). The specified monitoring device (1) can perform an individual operation.
