Reusable instrumentation, such as a medical instrument or tool, is decontaminated by applying pressure waves from multiple shockwave applicators and/or reflectors.

A drain cassette for a dialysis unit has a fluid channel between venous and arterial connection ports, and a valve may controllably open and close fluid communication between a drain outlet port and the venous connection port or the arterial connection port. A blood circuit assembly and drain cassette may be removable from the dialysis unit, e.g., by hand and without the use of tools. A blood circuit assembly may include a single, unitary member that defines portions of a pair of blood pumps, control valves, channels to accurately position flexible tubing for an occluder, an air trap support, and/or other portions of the assembly. A blood circuit assembly engagement device may assist with retaining a blood circuit assembly on the dialysis unit, and/or with removal of the assembly. An actuator may operate a retainer element and an ejector element that interact with the assembly.

The invention relates to an apparatus for preparing ready-to-use solutions for peritoneal dialysis that has a sterilization compartment; a filling line leading to the sterilization compartment and having a connector arranged at its end at the compartment side for connecting a disposable; a water treatment system arranged in the filling line; and a sealing system. The invention further relates to a disposable for preparing ready-to-use solutions for peritoneal dialysis in such an apparatus and to a method of preparing ready-to-use solutions for peritoneal dialysis using such an apparatus and such a disposable.

The invention relates to a dialysis treatment unit in which the connecting line to the central concentrate supply is also rinsed in the rinsing or cleaning process in order to prevent deposits therein.

In some embodiments, a medical system includes a dialysis machine having at least one outer surface to be disinfected at a given location, at least one disinfection sensor connected to the dialysis machine at the given location, the disinfection sensor including two or more electrode in fluid contact with the outside surface of the dialysis machine, and a conductivity sensor component in electrical contact with the two or more electrodes, the conductivity sensor component configured to send an electrical signal indicating a conductivity of a liquid on an outside surface of the dialysis machine and in contact with the two or more electrodes, a processor configured to receive the electrical signal and thereby determine a disinfection status of the given location, and a user interface configured to indicate the disinfection status of the given location.

Described herein are systems and methods for performing peritoneal dialysis. According to one aspect, the disclosure provides a sterile interface connection for connecting a water purification system to a disposable source of dialysate concentrates. The sterile interface connection can include a chamber comprising an inlet adapted to be connected to the water purification system on a proximal end and a valve on a distal end. The sterile interface connection can also include spring-loaded needle disposed in the chamber. The spring-loaded needle can move between a retracted configuration in which the spring-loaded needle is fully retracted into the chamber and the valve is closed and sealed, and an extended configuration in which the spring-loaded needle extends through the valve into the disposable source of dialysate concentrates.

A renal therapy apparatus includes a blood filter, a blood pump, a treatment fluid pump, and a control unit configured to control at least one of the blood pump or the treatment fluid pump during a filter cleaning sequence. In a first phase of the filter cleaning sequence, a first fluid including a blood-compatible and physiologically safe fluid is transferred back and forth across the insides and/or outsides of the blood filter. After the first phase, a second fluid is formed by mixing the first fluid with air. In a second phase of the filter cleaning sequence, the second fluid is transferred across the insides and/or outsides of the blood filter at least one time.

The present invention relates to a method for controlling a blood treatment apparatus, with the conveying of blood using a blood pump, with the patient venous tubing clamp closed, until a predetermined volume of fluid has passed out of the blood tubing set through the membrane and into the dialysis fluid chamber. It also relates to a control and regulating apparatus and a treatment apparatus. It further relates to a computer program, a computer program product and a digital storage medium.

A hybrid hemodialysis (HD)/peritoneal dialysis (PD) system includes: a reservoir; a weigh scale operably coupled with the reservoir; and at least one controller programmed to run (i) an HD treatment in which blood is pumped to a blood compartment of a dialyzer, fresh HD dialysis fluid is pumped to a dialysis fluid compartment of the dialyzer, and used HD dialysis fluid is pumped from the dialysis fluid compartment of the dialyzer to the reservoir, and at a different time (ii) a PD treatment in which fresh PD dialysis fluid is pumped to a patient and used PD dialysis fluid is pumped from the patient to the reservoir.
