Abstract: The disclosure relates to a dialysis machine that comprises a dialyzer, a fluid source, a first line connected to the fluid source, and a container containing bicarbonate. The container connects to the first line and the fluid flows from the fluid source, through the first line, to the container. The dialysis machine further includes a second line connected to the container, a flow rate sensor connected to at least one of the lines, a pressure sensor configured for detecting fluid pressure of the container, a display, and a data processing apparatus. The data processing apparatus is configured to receive signals from the flow rate sensor and the pressure sensor. The data processing apparatus is configured to calculate a size of the container based on the received signals.

Abstract: The disclosure relates to a method including determining a treatment time of a dialysis treatment for a patient, receiving, from at least a sensor of a dialysis machine, a dialysate flow rate, the dialysate comprising bicarbonate pumped out of a bicarbonate source, wherein the bicarbonate source has an initial amount of bicarbonate, and predicting that by end of the dialysis treatment no more than a threshold amount of bicarbonate will be left in the bicarbonate source, and in response, determining that a clearance value during the treatment is or will be higher than the threshold clearance value, and sending, to a balancing system, an instruction to reduce the dialysate flow rate to a reduced rate, wherein the reduced rate results in reducing a rate of bicarbonate pumped out of the bicarbonate source while maintaining a clearance value of the treatment at no less than the threshold clearance value.

Abstract: A dialysis system is provided that includes a dialysis machine and a potassium sensing device that is configured to measure the concentration of potassium in the patient's blood, in spent dialysate resulting from treating the patient, or in both. The potassium sensing device can be configured to generate a sensed value of the concentration of potassium. A control and computing unit, including a processor and a memory, is configured to receive the sensed value, compare the value with one or more values stored in the memory, and generate a control signal based on the comparison. A potassium infusion circuit uses the control signal to infuse supplemental potassium solution into the treatment dialysate, a replacement fluid, or both. The memory can include stored patient-historical and population data.

Abstract: Medical devices and peripheral devices can be configured to wirelessly communicate with each other and other devices through a connection between the devices. Peripheral devices may include weight scales, blood pressure monitors and/or other medical components that may be used in connection with measuring patient information related to a medical treatment by a medical device, such as a dialysis treatment performed by a dialysis machine. A medical function/data transfer device according to the system described herein may include multi-function capabilities to provide for a medical monitoring or treatment function as well as a data transfer function for transferring data between interconnected medical devices.

Abstract: A dialysis system (e.g., a hemodialysis (HD) system) can be designed to operate in alternative environments, such as disaster relief settings or underdeveloped regions. The dialysis system can include a solar panel for generating electricity to power the dialysis machine and an atmospheric water generator for extracting water from ambient air. The extracted water can be used to generate dialysate and saline on-site. One or more of the components of the dialysis machine can be discrete components that are configured to facilitate fast shipping and simple on-site assembly (e.g., at a remote location). In some implementations, the discrete components may be configured to be attached to an existing dialysis system (e.g., a dialysis system designed for operation in a traditional environment) to permit the dialysis system to operate in an alternative environment.

Abstract: Systems and methods for estimating the post-treatment ultrafiltration rate of a patient are provided. A medical device can be configured to determine an estimated post-treatment ultrafiltration rate based on one or more values associated with a patient prepared to undergo treatment with the medical device. The medical device can also be configured to compare the estimated post-treatment ultrafiltration rate with one or more threshold values. The medical device can be configured to have an alert module, which can be activated when the estimated post-treatment ultrafiltration rate exceeds the one or more threshold values.

Abstract: A leak may be detected in a heat exchanger of a hemodialysis device. A drain valve is opened by the controller, and then closed by the controller after a pre-selected time period. An initial pressure is determined in the spent dialysate circuit and stored in the memory. A system pressure is determined at periodic time intervals and compared to a pre-determined maximum pressure. The controller then determines whether the heat exchanger has a leak, in that in response to the system pressure exceeding a predetermined maximum pressure, a command is generated to execute an event including suspending a disinfectant operation with a disinfecting agent, and in response to the initial pressure subtracted from the system pressure being greater than a predetermined minimum pressure differential, a command is generated to execute an event including suspending the cleanse operation with the disinfecting agent.
