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 cardiac pump is arranged to mimic triphasic operation. The pump uses a fluid line formed from flexible tubing, along with a reciprocating actuator arranged to move between a free orientation and an occluding orientation. This allows a portion of the fluid line to be selectively occluded during movement of the actuator, enabling blood or other fluids to be peristaltically forced fluid towards a fluid outlet. The direction of operation of the actuator, and the selection of appropriate occluding or free orientations, allows the pump to be operated in a triphasic manner.

摘要： Described are fluid pumping and fluid handling systems, which may be suitable for use in medical devices, such as artificial or extracorporeal blood pumping systems. The systems can include a dual housing configuration for pneumatic actuation comprising a main housing containing a pump cassette comprising a pneumatically actuated pump and pneumatically actuated valves. The pump can include a pump actuation chamber and pump pneumatic port, and the valves can each include a valve actuation chamber and valve pneumatic port. Connecting tubes can be used to fluidly connect the pump actuation ports and valve actuation ports to a tube-support housing having a first side receiving one end of each connecting tube and a second side providing a pneumatic interface arranged to connect to an array of pneumatic receptacles on a base unit of the system to facilitate easy, compact and accurate pneumatic interconnection between the pump cassette and the base unit.

摘要： An adaptor for use in a blood conduit of an extracorporeal life support system. The adaptor includes a body defining a main passageway and an auxiliary port extending from the body with a passageway of the auxiliary port converging with the main passageway. The auxiliary port includes a hemostasis valve configured to selectively seal around a medical device inserted through the auxiliary port into the main passageway. An elastomeric valve may be positioned in the passageway of the auxiliary port spaced away from the hemostasis valve such that elastomeric valve is located between the hemostasis valve and the main passageway. In some instances, the hemostasis valve may be removably couplable to the auxiliary port.

摘要： The invention relates to an arrangement having a blood pump and a gas exchanger for extracorporeal membrane oxygenation. According to the invention, the blood pump is designed as a pulsatile blood pump and is arranged with the gas exchanger in the same housing. The pulsatile blood pump and the gas exchanger are preferably connected to the same gas source so that the blood pump can be pneumatically driven. The novel ECMO system has a simple design, is flexible, and in particular can be used directly on the patient.
