  • Patent number: 12611494
    Abstract: A thermal disinfection system and a method to perform a thermal disinfection procedure of fluid lines of a medical apparatus are disclosed herein. In an example, the thermal disinfection procedure comprises at least the steps of receiving a temperature signal from a temperature sensor, determining a measured temperature value of a fluid within a hydraulic circuit, receiving a pressure signal from a pressure sensor, determining a measured local atmospheric pressure value, and driving a heating unit to heat the fluid based on the measured temperature value and the measured local atmospheric pressure value.
    Type: Grant

  • Patent number: 11135346
    Abstract: In an embodiment, a dialysis machine includes a dialyser, a fluid line in fluid communication with the dialyser, an inlet valve enabling fluid to flow into the fluid line towards the dialyser during a dialysis treatment, a disinfectant line connected to the fluid line via a disinfectant valve upstream of the dialyser, the disinfectant valve enabling a disinfectant fluid to be provided to at least part of the fluid line during a disinfection procedure, and a controller programmed to open the inlet valve, while the disinfectant line is connected to a source of disinfectant fluid, to create a positive pressure gradient across the disinfectant valve as fluid flows into the fluid line towards the dialyser, the positive pressure gradient ensuring that the disinfectant fluid from the source of disinfectant fluid does not leak into the fluid line during the dialysis treatment.

  • Patent number: 10092686
    Abstract: A dialysis machine comprising a fluid circuit for providing a dialysis fluid to a dialyzer is disclosed. The fluid circuit comprises a tube with a first valve for providing a disinfectant fluid for disinfecting at least a part of the fluid circuit at disinfection of the dialysis machine. The tube with the first valve is arranged to provide the disinfectant fluid upstream the dialyzer and at a position in the fluid circuit where pressure is, during treatment, such that a pressure gradient between ports of the first valve is provided, the ports comprising at least a disinfectant fluid port and a fluid circuit port, such that the disinfectant fluid port of the first valve is enabled to be safely connected to a source of disinfectant also during treatment. A method of controlling such a dialysis machine and a computer program for controlling are also disclosed.
