  • Publication number: 20220362446
    Abstract: A dialysis system is disclosed. An example dialysis system includes a water treatment device configured to provide purified water and a dialysis machine including a dialysate holding tank, and a dialysate mixing pump connected to a source of concentrate. The dialysis machine is configured to prepare dialysate using the purified water by receiving an indication that a batch of dialysate is needed, transmitting a first message to the water treatment device to begin providing the purified water, and causing the dialysate mixing pump to pump a concentrate from the source of concentrate for mixing with the purified water to form the dialysate for storage in the dialysate holding tank. After the batch of the dialysate has been stored to the dialysate holding tank, the dialysis machine transmits a second message to the water treatment device to stop providing the purified water.

  • Patent number: 11400193
    Abstract: A system for monitoring water quality for dialysis, dialysis fluids, and body fluids treated by dialysis fluids, is disclosed. The system uses microelectromechanical systems (MEMS) sensors for detecting impurities in input water or dialysis fluid, and in the prepared dialysate. These sensors may also be used to monitor and check the blood of the patient being treated. These sensors include ion-selective sensors, for ions such as ammonium or calcium, and also include amperometric array sensors, suitable for ions from chlorine or chloramines, e.g., chloride. These sensors assist in the monitoring of water supplies from a city water main or well. The sensors may be used in conjunction with systems for preparing dialysate solutions from water for use at home or elsewhere.
