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.

An article configured to warm and monitor a patient during a dialysis treatment, the article includes one or more heating elements. The article also includes one or more sensors configured to monitor a condition of the patient during the dialysis treatment. The article also includes a fabric portion configured to receive the one or more heating elements and the one or more sensors and position the one or more heating elements and the one or more sensors on the patient during treatment. The article also includes a transmitter configured to transmit information from the one or more sensors to a dialysis machine and an electrical connector configured to provide power to at least one of the one or more heating elements and the one or more sensors.

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 peritoneal dialysis (“PD”) system includes a housing; a dialysis fluid pump housed by the housing; a dual lumen patient line extending from the housing; a filter set including a final stage filter located along a first line, and which includes a second line in parallel with the first line, the first line in fluid communication with a first lumen of the dual lumen patient line, and the second line in fluid communication with a second lumen of the dual lumen patient line; a pressure sensor located within the housing and positioned so as to sense a static or substantially static PD fluid pressure in the second lumen while fresh PD fluid is pumped through the first lumen and the final stage filter; and a control unit configured to use the sensed static or substantially static pressure in a pressure control routine for the dialysis fluid pump.

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.

A renal therapy system is disclosed. In an example, the renal therapy system includes a user interface device, such as a tablet computer. The renal therapy system also includes a renal therapy machine configured to perform a renal therapy. The renal therapy machine includes a data transfer interface configured to communicatively couple to the user interface device, a dialysis fluid pump, and a processor that operates a connectivity agent having an activated mode and a deactivated mode. When in the activated mode, the connectivity agent enables the processor to send data related to a performance of the renal therapy to a system hub. In the deactivated mode, the processor is prevented from sending the data to or receiving any data from the system hub. The user interface device is configured to receive data from and send data to the processor regardless of a status of the connectivity agent.

A water purification unit (30) fluidly connectable to a peritoneal dialysis preparator (50/60) and a cycler. The purification unit is connectable to a water source (20) and has a pump for flow of fluid from the unit to a purified water reservoir (40), the reservoir being fluidly connectable to the preparator which has a number of solute containers for dissolution of the solutes; each container being fluidly connectable to a chamber for receiving a solution of the solutes for preparation of a peritoneal dialysis fluid and the chamber being fluidly connectable to the cycler for the delivery and drainage of the peritoneal dialysis fluid to and from a patient. Purified water delivery to the reservoir is controlled by a first pressure sensor (72), and a second pressure sensor (74) between the reservoir and preparator provides a pressure differential between the first and second sensors to control a flow generator (76).

Constraining adaptive optimizations of a state of an operation module of a medical device includes determining if a new state has at least one operational parameter that is outside a constraint that has been provided to the medical device in a non-repudiable manner, accepting the new state if no operational parameters are outside any of the constraints, and reverting the medical device to a previous valid state if at least one operational parameter is outside at least one of the constraints. The adaptive optimizations may be provided using artificial intelligence along with relevant inputs thereto. The medical device may be a dialysis system. Constraint data may be provided to the medical device along with a one-way hash value of the constraint data using, for example, a SHA 256 hash. The one-way hash value may be digitally signed using a private key that is part of a public/private key pair.

A method for operating a dialysis machine to conduct a dialysis treatment on a patient (e.g., a peritoneal dialysis machine) may include transferring dialysate from a first bag, and automatically determining the dialysate from the first bag has completely transferred. After determining the dialysate has completely transferred from the first bag, switching from the first bag to a second bag of dialysate. The method may further include transferring dialysate from the second bag in response to the detection of the completed transfer of the first bag, and automatically determining the dialysate from the second bag has completely transferred. The method may further include determining if the respective first or second bag has completely transferred by comparing a dialysate bag volume transferred to the patient to a detected volume of the respective first or second bag. Systems with dialysis machines for performing such a method are disclosed as well.
