  • Patent number: 10518015
    Abstract: 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.

  • Patent number: 10391221
    Abstract: This disclosure relates to making medical solutions. In certain aspects, a method is performed by a data processing apparatus. The method includes introducing liquid into a container that contains a dissolvable solid concentrate in a manner so that a layer of solution above the solid concentrate is maintained at a depth that allows the liquid introduced into the container to agitate the solution adjacent to the solid concentrate to cause mixing of the solid concentrate with the solution.
