A hemodialysis machine includes a main body and a door connected to the main body. The door and the main body cooperate to define a non-removable chamber. The door is openable relative to the main body of the hemodialysis machine to allow a salt to be placed into the non-removable chamber when the door is in an open position. The main body further includes a fluid inlet, a fluid outlet, and a pumping mechanism. The fluid inlet and the fluid outlet are in fluid communication with the non-removable chamber. The pumping mechanism is configured to deliver a fluid from a fluid source to the non-removable chamber through the fluid inlet to mix with salt within the non-removable chamber to form a salt solution that exits the non-removable chamber through the fluid outlet.

The present specification discloses a dialysis system having a reservoir module with a reservoir housing defining an internal space, a surface located within the internal space for supporting a container that contains dialysate, and a conductivity sensor located within the internal space, where the conductivity sensor has a coil, a capacitor in electrical communication with the coil, and an energy source in electrical communication with the circuit.

A treatment device system includes a treatment machine for generating custom peritoneal dialysis solution and including at least one fluid conveyor, the treatment machine having a controller, the controller having a first memory, configured to produce a therapeutic fluid by causing the at least one fluid conveyor to mix purified water and at least one concentrate. The system also includes a user interface and a water purifier in fluid communication with and providing the purified water to the treatment machine, the water purifier including internal central controller, the internal central controller having a second memory, to control preparation of the purified water. A server is communicatively coupled with the treatment machine and a control line provides two way communication between the controller of the treatment machine and the internal central controller of the water purifier.

Dialysis systems and methods are described which can include a number of features. The dialysis systems described can be to provide dialysis therapy to a patient in the comfort of their own home. The dialysis system can be configured to prepare purified water from a tap water source in real-time that is used for creating a dialysate solution. The dialysis systems described also include features that make it easy for a patient to self-administer therapy.

The disclosure relates to a heater made from a layer of silicone rubber or similar material having one or more embedded heating elements and a conductive plate such as an aluminum plate positioned on a side of the layer of silicone rubber. The heater can be used to heat fluids necessary to generate a peritoneal dialysis fluid or heat peritoneal dialysis fluid prior to infusion into a patient. Systems that have one or more of the heaters of the invention to generate the peritoneal dialysis fluid and to heat the generated peritoneal dialysis fluid are provided.

A thermal protection system configured for use with a dialysate container or bag in a dialysis system is disclosed. The thermal protection system being configured so that when the dialysate container is subjected to a temperature greater than a predetermined temperature such as, when the dialysate container is heated within a microwave oven, the thermal protection system is configured to (i) prevent the flow of dialysate from the bag, (ii) indicate that the dialysate container has been subjected to a temperature greater than the predetermined temperature, or (iii) a combination thereof. In one embodiment, the thermal protection system is a circular hollow ring positioned within an exit port of the bag, the ring melting upon reaching the predetermined temperature to block the flow of dialysate. Alternatively, and/or in addition, the thermal protection system may be a thermally sensitive dye configured to change color upon being subjected to the predetermined temperature.

The present invention is directed to wall box for hemodialysis interface having two isolated zones. The first zone is a clean interface zone having sources of purified water and dialysis fluids. The second zone is a waste interface zone comprising waste connectors and a waste drain.

The present invention relates to a concentrate container having a concentrate that is configured to form a dialysis solution after its dilution with a diluting agent, in particular with water, wherein the concentrate container is in communication with a first connector having a first code that contains at least one piece of information on the concentrate; and wherein the concentrate container is furthermore in communication with a second connector whose second code differs from the first code, with the second code containing at least one piece of information on the dialysis solution.

A dialysis method and system for determining an amount of total chlorine in a partially purified water sample is disclosed. The system includes a water machine that produces at least partially purified water including an at least partially purified water sample and a dialysis machine that provides a dialysis treatment to a patient. The dialysis machine receives the at least partially purified water from the water machine to prepare dialysis fluid for the dialysis treatment. The system also includes a total chlorine detector configured to receive the at least partially purified water sample, at a first time apply a source voltage to the at least partially purified water sample, and at a second time stop applying the source voltage to the at least partially purified water sample and instead monitor a sensed electrical parameter to determine an amount of total chlorine in the at least partially purified water sample.
