摘要： Dialysis systems are disclosed comprising new fluid flow circuits. Systems may include blood and dialysate flow paths, where the dialysate flow path includes balancing, mixing, and/or directing circuits. Dialysate preparation may be decoupled from patient dialysis. Circuits may be defined within one or more cassettes. The fluid circuit fluid flow paths may be isolated from electrical components. A gas supply in fluid communication with the dialysate flow path and/or the dialyzer able to urge dialysate through the dialyzer and urge blood back to the patient may be included for certain emergency situations. Fluid handling devices, such as pumps, valves, and mixers that can be actuated using a control fluid may be included. Control fluid may be delivered by an external pump or other device, which may be detachable and/or generally rigid, optionally with a diaphragm dividing the device into first and second compartments.

摘要： A method of processing blood includes receiving from a touch screen user input data for a protocol for a wash procedure. The user input data includes a numeric value. The method includes storing the protocol in a memory, receiving an identifier from a user, determining if the identifier permits the user to modify the protocol and receiving a modification of the protocol from the user. The method includes providing a plurality of authorizations, a second authorization being a default and an administrator authorization permitting the user to change a setting. The method includes comparing a password to a password stored in memory and, if there is a match, determining that the password is associated with an administrator. If a command to change the setting is received, the command is applied to change the setting. The blood is processed employing a wash procedure using the modified protocol and the changed setting.

摘要： The present invention presents a novel oxygenator of the invention provides a revolutionary engineering design and management of the flow regime in a completely different way from the existing and accepted regime in the field of oxygenators, that further lower the risk levels associated with the use of oxygenators and reduces the manufacturing cost. The revolutionary technology is aimed to divert the world of blood oxygenation from the use of technology that relies on a fiber membrane or gas bubbles and causes substantial damage to the patient's blood, towards the use of technology that allows the exchange of gases without a membrane at all and is aimed to reduces risks and improves patient outcome.

摘要： Dialyzer systems can consolidate multiple technologies and functionalities of blood treatment systems in a significantly integrated fashion. For example, this disclosure describes dialyzer systems that include a magnetically driven and magnetically levitating pump rotor integrated into the dialyzer. Such a dialyzer can be used with treatment modules that include a magnetic field-generating pump drive unit. In some embodiments, the dialyzers include pressure sensor chambers with flexible membranes with which corresponding pressure transducers of the treatment modules can interface to detect arterial and/or venous pressures.

摘要： A method of performing dialysis includes: recirculating a dialysis fluid from a patient or a dialyzer for at least two cycles, each cycle contacting the dialysis fluid first with a zirconium phosphate layer followed by at least one of a urease layer, a zirconium oxide layer, or a carbon layer; storing the recirculated dialysis fluid in a storage container; and transferring the dialysis fluid from the storage container to the patient or the dialyzer. In one example, the zirconium phosphate layer and the at least one of the urease layer, the zirconium oxide layer, or the carbon layer is provided by a sorbent cartridge.

摘要： A cell processing system includes at least one processor connectable to a source container filled with a biological fluid, the processor including a spinning membrane configured to receive and separate target cells from the biological fluid, the target cells exiting at a first outlet, first and second containers selectively connected to the first outlet; and a magnet. The system also includes a controller configured to operate the spinning membrane to receive biological fluid and to direct the target cells to the first container, to pause to permit magnetic particles to be associated with the target cells in the first container, to operate the spinning membrane to receive the contents of the first container with the magnet applied to the target cells associated with the magnetic particles, to remove or deactivate the magnet, and to transfer the target cells to the second container.
