An assembly comprises a manifold configured to couple to a medical fluid cassette and a multi-lumen tube comprising a plurality of lumens within an outer wall of the multi-lumen tube. The manifold has a plurality of fluid connection ports and can be connected to the multi-lumen tube (e.g., via an adapter).

A dialysate mixing machine may be configured to make dialysate on demand using, among other things, a plurality of concentrates in solid tablet form. For example, a prescription may be received by the dialysate mixing machine indicating the particular chemical constituents and amounts of each chemical constituent to be included in the dialysate. Based on the prescription, the dialysate mixing machine can determine the number of tablets required for each chemical constituent (and, e.g., the required amounts of other chemical constituents that are not in tablet form). The tablets are automatically dispensed and mixed with purified water, bicarbonate, and sodium chloride in a mixing chamber to produce the dialysate according to the prescription. The dialysate mixing machine may be used with and/or coupled to a dialysis machine (e.g., a hemodialysis (HD) machine designed for home use) to provide the dialysate on demand for a dialysis treatment.

A secure artificial intelligence (AI) enabled wearable medical sensor platform is used for adaptive operation according to features and techniques described herein. Operational parameters are modified based on data inputs thereto that provide feedback to the AI systems of the wearable sensor platform. The described technology can facilitate adaptive optimizations provided by AI machine learning algorithms in a manner that can beneficially assist in the monitoring and treatment of a patient. For example, the system described herein may be used for the continuous monitoring of the physiological parameters and health of a patient's vascular access point (for example, the fistula) and may provide, among other things, early warnings of possible infection at the vascular access location.

A treatment device system includes a treatment machine for generating custom peritoneal dialysis solution and including at least one fluid conveyor, the treatment machine having a controller, the controller having a first memory, configured to produce a therapeutic fluid by causing the at least one fluid conveyor to mix purified water and at least one concentrate. The system also includes a user interface and a water purifier in fluid communication with and providing the purified water to the treatment machine, the water purifier including internal central controller, the internal central controller having a second memory, to control preparation of the purified water. A server is communicatively coupled with the treatment machine and a control line provides two way communication between the controller of the treatment machine and the internal central controller of the water purifier.

A dialysis machine (e.g., a peritoneal dialysis (PD) machine) can include a control unit configured to operate in a hybrid automated mode during a PD treatment. A processor in the control unit is configured to engage a pump during a fill phase of the PD cycle. The volume of fluid (e.g., dialysate) transferred to a patient line during the fill phase is monitored. After a dwell period, the pump is disengaged at the start of a drain phase of the PD cycle. Disengaging the pump can include: configuring valves of a disposable cassette to bypass the pump chambers of a disposable cassette; activating a bypass valve to shunt the patient line to a drain line; or moving a roller assembly of a peristaltic pump. The fluid transferred from the patient line to the drain line is monitored during the drain phase of the PD cycle.

A servicing regime for a disposable set of a medical fluid therapy machine is disclosed. In an example, a medical fluid delivery system includes a medical fluid therapy machine operating with a disposable set over multiple treatments to mix for each treatment at least one concentrate with purified water to form a medical fluid. The medical fluid delivery system also includes a sensor configured to measure an accuracy of the medical fluid mixed by the medical fluid therapy machine. The sensor is configured to produce a mixing accuracy output. The medical fluid delivery system further includes a computer programmed to analyze the mixing accuracy output provided by the sensor to determine whether the disposable set needs to be replaced.

A mobile dialysis therapy cart includes a top shelf; a cycler compartment positioned below the top shelf, the cycler compartment sized and shaped to house an APD cycler; a fluid bag management compartment sized and shaped to house at least two fluid bags; a drain compartment positioned below the fluid bag management compartment; and a plurality of wheels. The cart may include a heating device associated with the fluid bag management compartment and/or a sanitizing light source for sanitizing a location of a disposable set associated with the fluid bags.

A mobile cart for a medical device is disclosed. The cart is designed to transport a medical device such as a dialysis machine (e.g., a peritoneal dialysis (PD) machine). The medical device can be connected to a power supply included in the cart, where the power supply includes one or more energy storage devices (e.g., batteries), a charging circuit, and (optionally) an inverter. The cart can also include a number of features such as automatic brakes, UV light sterilization, sensors such as object detection safety features, environmental sensors, and the like. The cart can include electronic components that enables certain functionality such as hosting a wireless local area network or communicating wirelessly with the medical device. A docking station is also disclosed that enables wireless charging of the power supply such that neither the medical device nor the cart needs to be plugged into an external power supply.

A medical treatment system, such as a peritoneal dialysis system, may include a control and other features to enhance patient comfort and ease of use. For example, a cycler device may include a heater bag receiving section and a lid mounted to cover and uncover the heater bag receiving section, potentially enabling faster heating of a dialysate. A user interface may be moveable to be received into the receiving section and covered by the lid, if desired. The system may detect anomalous conditions, such as tilting of a housing of the system, and automatically recover without terminating a treatment. The system may include noise reduction features, such as porting pneumatic outputs to a common chamber, and others. The system may also automatically detect any one of several different solution lines connected to the system, and control operation accordingly, e.g., to mix solutions provided by two or more lines and form a needed dialysate solution. A cassette control surface may be arranged to have one or more ports that can detect a presence of a liquid, e.g., to identify if a cassette is leaking or has otherwise been compromised.

Methods, device, and systems for preparing peritoneal dialysis fluid and/or administering a peritoneal dialysis treatment are disclosed. In embodiments, peritoneal dialysis fluid is prepared at a point of use automatically using a daily sterile disposable fluid circuit and one or more long-term concentrate containers that are changed only after multiple days (e.g. weekly). The daily disposable may have concentrate containers that are initially empty and are filled from the long-term concentrate containers once per day at the beginning of a treatment.
