A blood purification device for blood purification therapy performed through a blood purifier, the blood purification device includes piping; a plurality of sensors of different detection types that are provided on the piping; and a liquid chemical identification unit that identifies a type of a cleaning/disinfection liquid chemical flowing through the piping by using the plurality of sensors. The liquid chemical identification unit is configured to be able to identify types of the liquid chemicals of at least not less than the number of the plurality of sensors by using the plurality of sensors.

An electromagnetic radiation (EMR) delivery system for delivering EMR at wavelengths, intensities, exposures, and durations to locations inside and/or outside a patient's body in, on, and surrounding a catheter and/or a catheter extension to prevent, reduce, and/or eliminate infectious agents in, on, or surrounding the catheter and/or catheter extension. A smart light engine box generates the therapeutic EMR, controls treatments, and monitors the health of the system. A fiber optic disposable makes at-home use of the EMR delivery system possible. Specific embodiments of the EMR delivery system for use with peritoneal dialysis catheters, dialysis accesses, and hemodialysis accesses are also disclosed.

A hemodialysis system is disclosed. The hemodialysis system includes a disposable set including a blood pumping tube, a fresh dialysate pumping tube, and a spent dialysate pumping tube. The hemodialysis system also includes a dialysis instrument including a blood pump head, a fresh dialysate pump head, a spent dialysate pump head, a first motor positioned and arranged to operate the blood pump head, a second motor positioned and arranged to operate the fresh dialysate pump head, and a third motor positioned and arranged to operate the spent dialysate pump head. When the disposable set is loaded into the dialysis instrument, the blood pumping tube comes into registry with the blood pump head, the fresh dialysate pumping tube comes into registry with the fresh dialysate pump head, and spent dialysate pumping tube comes into registry with the spent dialysate pump head.

The present disclosure relates to a disposable, which comprises a fluid line and a connector having a connector lumen, for fluidically connecting the fluid line to a first lumen of a first fluid guide of a port, which further comprises a second lumen. It further relates to a system with a disposable according to the present disclosure and with a port for establishing a fluid communication between at least one fluid line of the treatment apparatus, which fluid line is assigned to the interior of a blood treatment apparatus, and a connector of a fluid line of a disposable, which fluid line is assigned to the exterior of the treatment apparatus.

The present application relates to a method for disinfection of a temperature control device for human body temperature control during extracorporeal circulation which temperature control is conducted by use of a heat exchanger and a temperature control liquid circulating through the heat exchanger and the temperature control device. According to the present application, the temperature control device is connected to a temperature control liquid supply and, during operation of the temperature control device for human body temperature control, a disinfectant is selectively added to the temperature control liquid supply upstream of the temperature control device.

Dialysis systems for operating dialysis machines (e.g., peritoneal dialysis machines) for conducting dialysis treatments are disclosed. The dialysis system may include a spent dialysate container for receiving spent dialysate from a patient. In use, the spent dialysate containers are arranged and configured to provide one or more mechanical advantages to ease disposal of the spent dialysate. For example, the spent dialysate container may receive the spent dialysate from the patient and enable the patient or caregiver to dispose of the spent dialysate without requiring the patient or caregiver to lift bags of spent dialysate or incorporate lengthy drain lines. The spent dialysate container may include a reservoir to receive the spent dialysate, wheels to enable the patient or caregiver to transport the reservoir, mechanisms to facilitate disposal of the spent dialysate from the reservoir, a nozzle to dispose of the spent dialysate, and/or a disinfectant to disinfect the drain.

A medical fluid generation system is disclosed. In an example, a peritoneal dialysis fluid generation system includes water purification equipment configured to provide purified water; a presterilized tubing set including a container for storing peritoneal dialysis fluid; at least one glucose or buffer concentrate; and a hemodialysis machine in fluid communication with the water purification equipment. The hemodialysis machine includes at least one mixing pump for mixing the at least one glucose or buffer concentrate with the purified water to form peritoneal dialysis fluid, a dialysis fluid pump for delivering the peritoneal dialysis fluid to the container, and a control unit configured to control the at least one mixing pump to form the peritoneal dialysis fluid and the dialysis fluid pump to deliver the peritoneal dialysis fluid to the container.

A peritoneal dialysis system includes a housing; a dialysis fluid pump housed by the housing; a patient line extendable from the housing; and a hose reel located within the housing, the hose reel configured to coil the patient line when disconnected from a patient. The patient line may be a dual lumen patient line, wherein the dual lumen patient line is coiled about the hose reel during a disinfection sequence for disinfecting the dual lumen patient line and the dialysis fluid pump.

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.

Disclosed herein are devices and methods related to UV disinfection of a transfer catheter during peritoneal dialysis. The transfer catheter comprises a first and second end, the second end comprising a transfer valve. The transfer valve body comprises an inlet, outlet, and a flush hole. The valve core comprises a notch configured to allow fluid flow between the various flow paths. The valve core and body are positioned off axis with respect to the fluid flow path. The transfer catheter can allow for a small volume kill zone, which can minimize the amount of UV required to disinfect the catheter.
