A system and method for controlling a renal therapy device is provided. The system comprises a controller for performing a method comprising: receiving a first power level of a first battery to determine if the first power level of the first battery is above a threshold value and receiving a second power level of a second battery to determine if the second power level of the second battery is above the threshold value. When the first power level is above the threshold value, the controller causes the renal therapy device to be powered by the first battery. When the first power level is below the threshold value, and the second power level is above the threshold value, the controller causes the renal therapy device to be powered by the second battery. The first battery is electrically isolated from the second battery.

In some examples, a connector includes a plug configured to mechanically couple with a socket to establish fluid communication from a first conduit to a second conduit. The plug is configured to mechanically engage the first conduit and the socket is configured to mechanically engage the second conduit. In examples, the plug is configured to insert into a socket well of the socket. The connector includes a clamp head configured to mechanically engage the plug when the plug mechanically couples with the socket. The clamp head is configured to mechanically engage the plug to help sustain the mechanical coupling of the plug and the socket. In some examples, the connector may include an output device configured to provide an output indicating when the plug is mechanically coupled with the socket.

A portable and wearable renal therapy system is provided. The system comprises: a purification device configured to remove toxins from process fluid and deliver a therapeutic substance to the process fluid; and a drug delivery device coupled to the purification device. The drug delivery device comprises: a reservoir for a fluid comprising a therapeutic substance; and a fluid connection coupling the drug delivery device with the purification device, the fluid connection configured for fluidly communicating the reservoir with the process fluid.

An artificial kidney and its supportive device comprising a catheter having an internal semipermeable membrane tube to act as an artificial kidney. Said catheter comprising a proximal portion having a semipermeable membrane tube, a blood/infusion lumen, a dialysate lumen and side holes, while a distal portion having a dual septa port assembly. Said supportive device comprising a device house with its cover that covers its internal cavity that includes sorbent bags with different sizes and arrangement, a screen, buttons , set knobs, two contactless conductivity cells, bidirectional rotary pumps, rotary valves, pressure sensors, a slot for memory card, a temperature sensor, scales, an IV pole and a blood leak detector.

A method comprising: inserting the catheter having an internal semipermeable membrane tube that acts as artificial kidney into a suitable vein or artery, then using the supportive device to supporting, facilitating, and controlling the operation of the artificial kidney and to managing the dialysate inflow and outflow to and from the dialysate lumen within the catheter and also to managing the blood inflow and outflow to and from the infusate/blood lumen within the catheter to be on opposite direction across the semipermeable membrane of the artificial kidney.

The invention relates to a dialysis device that provides recirculating flow dialysis in a wearable and portable format. It uses an exchangeable purification unit holding a volume of dialysate and/or a sorbent system for the in-situ regeneration of dialysate. The invented dialysis device comprises a carrier that is mounted on a replaceable cartridge. The carrier holds the electronics, user-interface, actuators and sensors. It actuates, controls and monitors the dialysis operation. The cartridge is a replaceable part that is connected to the patient via a flexible tubing. It consists of a reusable housing with a memory chip and holds a disposable inlay containing the purification unit with fluid lines, connectors, dialysate and/or sorbents in combination with a nanofilter. The cartridge is intended for use during the day, as a wearable system. The cartridge can be enlarged with an extension set to offer more capacity. The extended cartridge is intended to be used during the night as a bedside device.

The invention relates to devices, systems, and methods for conditioning a zirconium oxide sorbent module for use in dialysis after recharging. The devices, systems, and methods can provide for conditioning and recharging of zirconium oxide in a single system, or in separate systems.

The present invention relates to a method for preparing a macromolecular composition comprising indene-derivatives. The invention also relates to the macromolecular compositions per se, and to methods of using the macromolecular compositions. The macromolecular compositions are useful for undergoing subsequent reactions with small molecules.

A graphene oxide-based membrane There is provided a graphene oxide-based membrane comprising a substrate and a plurality of layers of single-layered graphene oxide formed on the substrate, each of the plurality of layers of single-layered graphene oxide is functionalised by at least one diamine functional group, wherein interlayer spacing between two adjacent layers of single-layered graphene oxide is ≤ 10 Å. The membrane may be comprised in an electrocapacitive unit. There is also provided a method of forming the membrane.

Apparatus and method for photo-chemical oxidation are disclosed herein. In one embodiment, a system for treating a dialysis fluid includes: a nanostructured photo-electrochemical anode; a source of light configured to illuminate the photo-electrochemical anode; and a cathode that is permeable to oxygen provided to the dialysis fluid and non-permeable to a liquid of the dialysis fluid. The photo-electrochemical anode is configured to remove urea from the dialysis fluid by converting the urea in the dialysis fluid into oxidation products through a photo electrochemical reaction.

A dialysis method to enable a patient to undergo both peritoneal dialysis and extracorporeal blood treatments is disclosed. The method includes determining, via a base unit controller, whether a peritoneal dialysis treatment or an extracorporeal blood treatment is to be performed. If the peritoneal dialysis treatment is to be performed, the method includes operating first software instructions that cause a base unit to use a first fluid stored in a fluid container. If the extracorporeal blood treatment is to be performed, the method includes operating second software instructions that cause the base unit to use a second, different fluid from an online source and selectively move the second, different fluid to a blood treatment unit for use in the extracorporeal blood treatment. The blood treatment unit is operable with the base unit to perform the extracorporeal blood treatment on a patient.
