A dialysis service box for centralized control and plumbing arrangement of a dialysis machine is disclosed. The dialysis service box includes a plumbing arrangement with a warm water inlet and a cold water inlet in fluid flow communication with a temperature mixing component. The thermostatic mixing component mixes the cold water and the warm water to produce mixed water maintained at a predetermined temperature between the temperature of the cold water and the temperature of the warm water. The dialysis service box can be universally installed to operate, control and adjust any dialysis machine that requires supply connection, waste connection, backflow preventer, thermostatic mixing component, a trap primer, or any combination of the foregoing.

A dialysis machine includes a dialyzer (1), a dialysate feed system (5) having a feed line (52), and a discharge system (6) having a discharge line (62). The machine further includes ultrafiltration control elements (UF) and back-filtration control elements (RF). The feed line is provided with a constriction (520) and with elements for measuring the pressure difference (523, 524) across the terminals of the constriction. The feed system further includes a ventricle bag (50), and pressurizer elements (70) for putting the ventricle bag (50) under pressure. The machine further includes an open/close system (C5, C5′) for opening/closing the discharge line (62) and the back-filtration control elements cause the discharge line (62) to close, and control the pressure applied to the ventricle bag (50), as a function of the pressure difference measured across the terminals of the constriction (520), so as to obtain a given flow rate of dialysate.

A disposable cartridge for use in a hemodialysis machine has a blood flow path for carrying a volume of blood to be treated in a dialyser and a dialysate flow path, isolated from the blood flow path, for delivering a flow of dialysate solution through the dialyser. The cartridge is received in an engine section of the machine. The engine section has first and second platens which close when the cartridge is inserted to retain the cartridge. Actuators and sensors arranged on the second platen control operation of the cartridge.

An apparatus for extracorporeal treatment of fluid and a process of setting up a medical apparatus for the delivery or collection of fluids are disclosed. According to the apparatus and the process, a control unit (10) is configured calculate set values of two or more of the fluid flow rates by imposing that an emptying time of containers of fresh fluid (16, 20, 21, 26) and/or a filling time of a waste container is substantially same as, or multiple of, the emptying time of one or more of the other containers of fresh fluid.

The filter system having a filter and a filter holder, wherein the filter is connected to an upper and a lower filter cap, wherein on the circumference of the filter caps a cross-sectionally T-shaped fixing aid is respectively mounted, having a laterally projecting transverse web, which are vertically aligned with each other, wherein on an outer side of the housing of the filter holder two filter fixings are mounted with grooves in which the transverse webs can be suspended, is characterized in that four hydraulic ports project laterally from the filter and/or the filter caps, which are vertically aligned with each other, and that the filter holder has four connection connectors, which can be advanced by an upper and a lower closure mechanism against spring force until they engage in an end position in which the connection connectors are tightly connected to the hydraulic connections.

Disclosed herein are systems, devices, and methods for flowing fluid for radially expanded particle distribution within a laminar flow. In some variations, a system for cultivating tissue may comprise a bioreactor comprising an inlet, a substrate arranged in the bioreactor, and a diffusion module configured to transfer fluid from the inlet to the substrate. The diffusion module may comprise a porous material having at least one tortuous conduit extending between a first surface of the porous material and a second surface of the porous material.

This disclosure relates to a blood treatment system including a blood treatment machine, a dialyzer configured to be coupled to the blood treatment machine, a blood line having a first end configured to be connected to the dialyzer and a second end configured to be connected to a needle for insertion into a patient, and one or more sensors operable to transmit, to the blood treatment machine, data related to tension along the blood line. The blood treatment machine is configured to take action in response to the data received from the one or more sensors.

An example peritoneal dialysis system is disclosed. The example peritoneal dialysis system includes an automated peritoneal dialysis (“APD”) machine configured to remove ultrafiltrate (“UF”) from a patient and record how much UF has been removed. The APD machine operates according to a prescription to remove the UF. The system also includes a server in communication with the APD machine. The server analyzes the UF data to determine if the prescription is to be modified to compensate for changes to the patient's renal function or renal transport characteristics.
