A stationary dialysis system includes at least two separate water preparation units, preferably of the osmosis type, which can be fluidically connected and/or separated to/from at least two separate ring lines according to selectable supply variants. A plurality of fixed, unchangeable hydraulic circuits representing the supply variants can be introduced into a circuit receiving means of the dialysis system for fluidically connecting and/or separating of the water preparation units to/from the ring lines.

Devices, systems, and methods herein relate to predicting infection of a patient. These systems and methods may comprise illuminating a patient fluid in a fluid conduit from a plurality of illumination directions, measuring an optical characteristic of the illuminated patient fluid using one or more sensors, and predicting an infection state of the patient based at least in part on the measured optical characteristic.

Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for performing dialysis. In one aspect, a dialysis hub receives a request to use a dialysis machine. The dialysis hub transmits a list of available dialysis machines. The dialysis hub receives a request to reserve use of the dialysis machine, and transmits a reservation to use the dialysis machine

Dialysis systems for operating dialysis machines (e.g., peritoneal dialysis machines) for conducting dialysis treatments are disclosed. The dialysis system may include a spent dialysate container for receiving spent dialysate from a patient. In use, the spent dialysate containers are arranged and configured to provide one or more mechanical advantages to ease disposal of the spent dialysate. For example, the spent dialysate container may receive the spent dialysate from the patient and enable the patient or caregiver to dispose of the spent dialysate without requiring the patient or caregiver to lift bags of spent dialysate or incorporate lengthy drain lines. The spent dialysate container may include a reservoir to receive the spent dialysate, wheels to enable the patient or caregiver to transport the reservoir, mechanisms to facilitate disposal of the spent dialysate from the reservoir, a nozzle to dispose of the spent dialysate, and/or a disinfectant to disinfect the drain.

A dialysis system includes a dialysis machine comprising a motorized autoconnection mechanism, a fluid supply line connected to a source of dialysis fluid, and a cassette for use with the dialysis machine. The cassette includes a frame, a pump chamber within the frame, a first set of valves for routing the dialysis fluid from the fluid supply line to the pump chamber, and a second set of valves for routing the dialysis fluid from the pump chamber to a patient line. The cassette also includes a plurality of ports communicating with the first and second set of valves. Each port includes an integral spike. The motorized autoconnection mechanism is configured to move the fluid supply line and the patient line automatically so as to be spiked open respectively by the plurality of ports of the cassette.

A peritoneal dialysis (“RD”) system includes a cycler including an actuation surface having a peristaltic pump actuator; a manifold assembly including a rigid manifold having first and second chambers (110a, 110b), the rigid manifold configured and arranged to be abutted against the actuation surface for operation, a peristaltic pump tube (124gh) extending from the first chamber (110a) to the second chamber (110b) of the rigid manifold, a dialysis fluid container line (124b) extending from the first chamber (110a), and a branch line (124c) extending between the dialysis fluid container line (124b) and the second chamber (110b); and a control unit configured to cause the peristaltic pump actuator to actuate the peristaltic pump tube (124gh) to pump dialysis fluid from the branch line (124c) into the second chamber (100b) and from the second chamber (110b) into the first chamber (110a).

A sensor assembly measures characteristics of a fluid entering or exiting a patient via a catheter. The sensor assembly includes a flow tube that accepts the fluid at a first end thereof expels the fluid at a second end thereof, a plurality of sensors disposed about the flow tube, the sensors including at least one temperature sensor that measures temperature of the fluid and at least one pressure sensor that measures pressure of the fluid, and a connector that connects the sensor assembly to the catheter. The sensors may also include a clarity sensor, a conductivity sensor, a flow sensor, and/or an air detector. The sensor assembly may also include a wireless communication device that provides wireless communication. The sensor assembly may communicate with a dialysis machine via a network. The dialysis machine may be a peritoneal dialysis machine.

A dialysate mixing machine may be configured to make dialysate on demand using, among other things, a plurality of concentrates in solid tablet form. For example, a prescription may be received by the dialysate mixing machine indicating the particular chemical constituents and amounts of each chemical constituent to be included in the dialysate. Based on the prescription, the dialysate mixing machine can determine the number of tablets required for each chemical constituent (and, e.g., the required amounts of other chemical constituents that are not in tablet form). The tablets are automatically dispensed and mixed with purified water, bicarbonate, and sodium chloride in a mixing chamber to produce the dialysate according to the prescription. The dialysate mixing machine may be used with and/or coupled to a dialysis machine (e.g., a hemodialysis (HD) machine designed for home use) to provide the dialysate on demand for a dialysis treatment.

A medical treatment system, such as peritoneal dialysis system, may include control and other features to enhance patient comfort and ease of use. For example, a peritoneal dialysis system may include patient line state detector for detecting whether a patient line is primed before it is to be connected to the patient. The patient line state detector can also the ability to detect whether a patient line has been properly mounted for priming. Both patient line presence/absence and fill state can be determined using an optical system, e.g., one that employs a single optical sensor.

A dialysis system includes: (i) a source of water made suitable for a dialysis treatment; (ii) at least one concentrate for mixing with the water from the source; (iii) a dialysis fluid pump; and (iv) a disposable set operable with the dialysis fluid pump and in fluid communication with the source of water and the at least one concentrate, the disposable set including a container having a first end and a second end, the container configured to allow the water and the at least one concentrate pumped by the dialysis fluid pump to enter at the second end and exit from the first end to mix for the dialysis treatment.
