摘要： 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.

摘要： The present disclosure relates to a system, method, and apparatus for electronic patient care. In the process of providing comprehensive care to patients including ordering and delivering medical treatments, such as medications, there is great potential for critical information to be not properly communicated, or treatment decisions to be made without ready access to complete information. Medication errors may be responsible for hundreds of deaths and may injure thousands or even millions of people each year in the United States alone. Sources of medication errors include administering the wrong medication, administering the wrong concentration of medication, delivering the medication at the wrong rate, or delivering the medication through the wrong route. A method implemented by an operative set of processor executable instructions configured for execution by a processor is disclosed. The method includes the acts of: communicating data between a monitoring client and a base as long as a link quality value is above a predetermined threshold; entering into a headless state if the link quality value falls below the predetermined threshold, wherein in the headless state, communications between the monitoring client and the base are suspended, and a message is displayed on a user interface to move the monitoring client and the base closer together; and remaining in the headless state as long as the link quality value remains below the predetermined threshold. The method also includes the acts of determining if the link quality value returns above the predetermined threshold; and exiting the headless state if the link quality value has returned to above the predetermined threshold.

摘要： There is disclosed herein dialysis systems, including a variety of systems and methods that would make hemodialysis more efficient, easier, and/or more affordable. One aspect of the invention is generally directed to new fluid circuits for fluid flow. In one set of embodiments, a hemodialysis system may include a blood flow path and a dialysate flow path, where the dialysate flow path includes one or more of a balancing circuit, a mixing circuit, and/or a directing circuit. Preparation of dialysate by the preparation circuit, in some instances, may be decoupled from patient dialysis. In some cases, the circuits are defined, at least partially, within one or more cassettes, optionally interconnected with conduits, pumps, or the like. In one embodiment, the fluid circuit and/or the various fluid flow paths may be at least partially isolated, spatially and/or thermally, from electrical components of the hemodialysis system. In some cases, a gas supply may be provided in fluid communication with the dialysate flow path and/or the dialyzer that, when activated, is able to urge dialysate to pass through the dialyzer and urge blood in the blood flow path back to the patient. Such a system may be useful, for example, in certain emergency situations (e.g., a power failure) where it is desirable to return as much blood to the patient as possible. The hemodialysis system may also include, in another aspect of the invention, one or more fluid handling devices, such as pumps, valves, mixers, or the like, which can be actuated using a control fluid, such as air. In some cases, the control fluid may be delivered to the fluid handling devices using an external pump or other device, which may be detachable in certain instances. In one embodiment, one or more of the fluid handling devices may be generally rigid (e.g., having a spheroid shape), optionally with a diaphragm contained within the device, dividing it into first and second compartments.

摘要： The present invention generally relates to hemodialysis and similar dialysis systems, including a variety of systems and methods that would make hemodialysis more efficient, easier, and/or more affordable. One aspect of the invention is generally directed to new fluid circuits for fluid flow. According to one aspect, a blood pump is configured to pump blood to a dialyzer of a hemodialysis apparatus, the blood pump comprising a pneumatically actuated or controlled reciprocating diaphragm pump. In an embodiment, the diaphragm of the pump comprises a flexible membrane formed or molded to generally conform to a curved inner wall of a pumping chamber or control chamber of the pump, wherein the diaphragm is pre-formed or molded to have a control side taking a convex shape, so that any elastic tension on the diaphragm is minimized when fully extended into a control chamber of the pump. In another aspect, a system for monitoring the adequacy of blood flow in a blood line of the hemodialysis apparatus allows a controller to suspend dialysate pumping operations if the adequacy of blood flow in the blood line is sub-optimal, and to present information on a display on the quality of blood flow in the blood line.

摘要： The present disclosure provides hemodialysis and similar dialysis systems, e.g., systems able to treat blood or other bodily fluids extracorporeally. In certain aspects, the system includes a variety of systems and methods that would make hemodialysis more efficient, easier, and/or more affordable. In one aspect, the system includes four fluid paths: blood; inner dialysate; outer dialysate and dialysate mixing. In some embodiments, these four paths are combined ina single cassette. In other embodiments, these four paths are each in a respective cassette. In still other embodiments, two or more fluid paths are included on one cassette.
