Abstract: A medicament preparation system includes a water purification module and a medicament proportioning module that is interoperable with a replaceable fluid circuit. The fluid circuit includes a purified water inlet, a product medicament outlet, and a plurality of pumping tube segments. At least a first concentrate container is connected by at least a portion of the fluid circuit to the product medicament output and a first concentration measurement sensor station is positioned in a flow path. A controller is programmed to calculate iteratively a concentration of a first concentrate from the first concentrate container and the purified water from a signal generated by the first concentration measurement sensor station and to regulate one or both of a first pumping actuator engaged with the first pumping tube segment and a second pumping actuator engaged with the second pumping tube segment, responsively to the concentration of the first concentrate and water.

Abstract: A peritoneal dialysis system includes a cycler comprising a control unit and a pump actuator. The peritoneal dialysis system also includes a disposable set operable with the cycler and in fluid communication with a source of water made suitable for peritoneal dialysis (“WFPD”) and a source of concentrate. The disposable set includes a pumping cassette comprising a pump chamber configured to be actuated by the pump actuator and a mixing container. The control unit is programmed to cause (i) the pump actuator to operate the pump chamber to pump a first amount of the WFPD to the mixing container, (ii) the pump actuator to operate the pump chamber to pump a prescribed amount of concentrate from the concentrate source to the mixing container, and (iii) the pump actuator to operate the pump chamber to pump a second amount of the WFPD to the mixing container.

Abstract: A personalized chronic care apparatus is disclosed herein. An example apparatus includes a server operating over a network, software stored on the server, and a compliance entry feature configured to receive compliance information related to a patient. The software includes an automated learning method for creating an overall kidney maintenance plan that specifies one or more controllable variables as actions performed by the patient to prevent or reduce complications associated with chronic kidney disease (“CKD”). The automated learning method is configured to perform an evaluation to determine whether a selected controllable variable is to be included in the overall kidney maintenance plan by confirming when (i) a worsening of kidney function is not determined between first evaluation data and second evaluation data over a testing period, and (ii) the compliance information provides a confirmation that the selected controllable variable was modified over the testing period.

Abstract: A dialysis machine (e.g., a peritoneal dialysis (PD) machine) can include a safety feature that enables the dialysis machine to automatically identify the connections made by a user in preparation for treatment. A smart connector is disclosed that uses a split RFID device that is operational when a first portion of the connector is mated to a second portion of the connector, and is not operational when the first portion is disconnected from the second portion. In an embodiment, the split RFID device incorporates an RFID chip in the first portion of the connector and an antenna in the second portion of the connector. In an embodiment, the RFID chip can store a tag that encodes information that indicates a formulation or a volume of a dialysis bag connected to the ports of a disposable cassette such that the dialysis machine can automatically discover the configuration of the dialysis setup.
