A dialysis machine (e.g., a peritoneal dialysis (PD) machine) can include a pressure sensor mounted at a proximal end of a patient line made of a distensible material that provides PD solution to a patient through a catheter. During treatment, an occlusion can occur at different locations in the patient line and/or the catheter. When an incremental volume of additional solution is provided to the patient line while the occlusion is present, a change in pressure results. The change in pressure depends on the dimensions and the distensibility of the non-occluded portion of the patient line. If the change in pressure, the incremental volume, the properties related to the distensibility of the patient line, and some of the dimensions of the patient line are known, the location of the occlusion can be inferred. The occlusion type can be inferred based on the determined location.

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.

A dialysis cassette includes a cassette housing having a plurality of channels fluidly coupled to a plurality of connectors and a plurality of valves disposed within the plurality of channels. The dialysis cassette also includes a pump assembly disposed within the cassette housing. The pump assembly includes a pump housing and a flexible rotor having a plurality of flexible vanes, where the flexible rotor is rotatable in either a clockwise direction or a counterclockwise direction to move a fluid through the plurality of channels.

A method of preserving a sorbent device of a dialysis system, the method comprising—after administering a first dialysis treatment at the dialysis system and before administering a second dialysis treatment at the dialysis system—circulating a fluid through the sorbent device to prevent matter within the sorbent device from solidifying and circulating the fluid through a filter coupled to an outlet of the sorbent device to remove contaminants from the fluid.

The present disclosure relates to a method for executing a sharing enabler of a registered medical treatment machine. The registered medical treatment machine is used in a shared medical treatment system. The method comprises the method steps: Providing a registration procedure for registering the medical treatment machine in the shared medical treatment system; Receiving an initiation request for initiating a medical treatment for a patient, being registered in the shared medical treatment system; Checking whether the received initiation request is valid by receiving a confirmation signal and if yes: Unlocking the medical treatment machine in reply to the received confirmation signal for use for the patient; Operating the medical treatment machine according to a treatment procedure in a sharing mode.

A peritoneal dialysis machine that includes a preparator as well as a cycler to form the peritoneal dialysis system. The system delivers purified water into one or more containers with different powders to create a concentrate and then moves this concentrate to a mixing bag to create the peritoneal dialysis fluid (PDF). The cycler then delivers fresh PDF to the patient and removes waste fluid via the drain outlet. A volumetric approach controls the hydraulic flow paths that introduce purified water to the powder concentrates, provide mixing of the concentrate to form the PDF and delivery of the freshly made PDF to the patient. Different configurations of hydraulic flow/pressure generators are provided in the fluid paths to provide optimization of the flow of water through the fluid system to create the correct powder concentrates and subsequent peritoneal dialysis fluid for cycling, for example being provided in a disposable cassette.

A treatment device system includes a treatment machine for performing a therapy on a patient, the treatment machine including at least one fluid conveyor and a controller, the controller having a first memory, to cause the at least one fluid conveyor to produce a therapeutic fluid by mixing purified water and at least one concentrate. The system also includes and a water purifier in fluid communication with and providing the purified water to the treatment machine. A wired or wireless control line provides two way communication between the controller of the treatment machine and the internal central controller of the water purifier, wherein the controller of the treatment machine transmits data via the control line to the internal central controller of the water purifier for control of the water purifier, the data provided based on at least one of the operator inputs received via the user interface.

A method and a system comprising an integrated water purifying apparatus with a pre-filter circuit including a particle filter and an activated carbon filter arranged to produce pre-treated water; a fluid circuit arranged to receive pre-treated water from the pre-filter circuit, the fluid circuit including an RO-pump and a Reverse Osmosis (RO) device arranged to produce purified water; a heating device arranged to heat purified water from the RO device to a temperature above 65°0 C.; the water purifying apparatus further arranged to heat disinfect the fluid circuit using the heated purified water. The system further comprises a line set connected to the purified water outlet connector at a water line connector of the line set, wherein the line set includes at least one sterile sterilizing grade filter arranged to further filter the purified water.
