The system is configured to allow convenient and safe use in a home environment or a critical care environment as well as others affording safety, reliability, and a compact form factor.

The invention relates to a system for treating blood, which includes a single cassette capable of carrying out the various CRRT treatments.

The document describes a system which is easy to move in order to allow travelling anywhere in the world. The document provides different potential features and embodiments such as the container support, the loading system, the shape of the housing, . . .

Dialysis systems are disclosed comprising new fluid flow circuits. Systems may include blood and dialysate flow paths, where the dialysate flow path includes balancing, mixing, and/or directing circuits. Dialysate preparation may be decoupled from patient dialysis. Circuits may be defined within one or more cassettes. The fluid circuit fluid flow paths may be isolated from electrical components. A gas supply in fluid communication with the dialysate flow path and/or the dialyzer able to urge dialysate through the dialyzer and urge blood back to the patient may be included for certain emergency situations. Fluid handling devices, such as pumps, valves, and mixers that can be actuated using a control fluid may be included. Control fluid may be delivered by an external pump or other device, which may be detachable and/or generally rigid, optionally with a diaphragm dividing the device into first and second compartments.

In one aspect, a dialysis fluid cassette includes an inlet fluid line, multiple outlet fluid lines, and a valve including an actuation feature by which the valve can be rotated to fluidly communicate the inlet fluid line with a selected fluid line of the multiple outlet fluid lines.

Aspects of the present disclosure relate to systems and methods for injection and retraction of a fluid. The system includes a switch configured to be activated, wherein activation of the switch activates an electrical control system. The system further includes a linear actuator that interfaces with the electrical control system. The electrical control system causes the linear actuator to depress a plunger, keep the plunger depressed for a predetermined time, and retract the plunger after the predetermined time. The system further includes a fluid reservoir engageable with the plunger, wherein the depression of the plunger causes fluid to be injected from the fluid reservoir into a connector and the retraction of the plunger causes fluid to be retracted into the fluid reservoir and out of the connector.

A peritoneal dialysis (“PD”) system includes a cycler having a micropump actuator, a pressure transducer, and at least one valve actuator; a disposable set including a micropump head sized and shaped for mating with and being driven by the micropump actuator, a pressure sensor configured to operably communicate with the pressure transducer, and at least one fluid valve portion or a portion of at least one fluid line for interfacing with the at least one valve actuator; and a control unit, wherein the disposable set may be arranged to allow, and the control unit may be programmed to operate the micropump actuator and the at least one valve actuator, so that fresh and used dialysis fluid flows through the micropump head in a same direction. The system may also dampen pressure fluctuations via pressure pods, and may analyze the outputs from the pressure pods for patient empty and occlusion detection.

Pressure sensors, including pressure sensors for automated peritoneal dialysis (APD) systems, and associated systems, devices, and methods are disclosed herein. In one embodiment, an APD system includes a diaphragm positioned over an opening in a disposable set that includes one or more fluid lines. The diaphragm is affixed to the disposable set about a periphery of the opening. The APD system further includes a pressure sensor configured to measure a pressure of fluid flowing through the disposable set. The pressure sensor includes a load cell and an indenter. The indenter can be moveable along an axis such that, when the diaphragm is aligned with the axis, a convexly curved surface of the indenter can be positioned against the diaphragm. When the indenter is contacting the diaphragm, the load cell can measure a force applied to the load cell by the diaphragm and/or by the fluid flowing through the disposable set.

A system and method are disclosed for the automated collection of dialysis data. An example method includes receiving and aggregating dialysis data comprising a fill volume amount and a drain volume amount for at least one continuous ambulatory peritoneal dialysis (“CAPD”) cycle. The method also includes calculating an amount of ultrafiltration removed for each CAPD cycle by subtracting the fill volume amount from the drain volume amount for the respective CAPD cycle, and storing ultrafiltration data that is indicative of the amount of ultrafiltration removed as part of the aggregated dialysis data. The method further includes determining or receiving an indication that a dialysis machine is connected. After the dialysis machine is connected, the method includes transmitting the aggregated dialysis data to the dialysis machine to enable the aggregated dialysis data to be combined with additional dialysis data generated by the dialysis machine for determining total dialysis data.

A personalized chronic care system including (i) a sensor; (ii) a data receiving device separate from the sensor and configured to receive data directly or indirectly from the sensor; (iii) a data analytics device separate from the sensor and including at least one algorithm configured to analyze the sensor data and provide an analyzed data outcome; and (iv) at least one output device separate from the sensor and in communication with the data analytics device, the at least one output device configured to receive and communicate the analyzed data outcome to a health care provider.
